Laser engraver water pump is a circulation water pump that driven by a brushless dc motor, it also named laser machine pump or laser chiller pump. It is one of the core component of the laser engraver cooling system.

As a small circulation water pump, it’s main function is to circulate the water and cooling the laser generator of the laser equipment. And controls the work temperature of the laser generator to keep it normally working for a long term. The laser generator will continuously generate high temperature, during the long-term operation of the laser equipment. It will affect the normal operation of the laser generator, if the temperature is too high. Therefore, people usually use a laser chiller pump to circulate water to control the laser machine temperature .

What is the working principle of the laser engraver water pump?

The working principle of the laser engraver is to inject a certain amount of water into the stainless steel water tank in the chiller machine. And cool the water through the refrigeration system of the chiller. Then use the water booster pump transfer the low-temperature cooling water to cool the laser engraver equipment. The chilled water will take away the heat in the laser machine. Then, the water flows back into the water tank. It will achieve the cooling effect through water circulation.

How to choose the water lift for the laser engraver water pump?

People always focus on the cooling capacity of laser chillers, when people purchase laser chillers. However, most of them ignore the important factors such as its water head and water flow. The cooling capacity of the chiller represents the compressor’s ability to generate refrigeration. While the water flow represents the ability of the chiller to remove heat.

The speed of the water flow reflects the water head of the laser engraver water pump. The water flow rate will very slow, if the water head of the pump is very low. This leads to the cooled water in the water tank can not be flow to the laser in time. So that, the heat in the laser engraving machine equipment can not be taken away in time. Then this will result in a phenomenon.  That is, the chiller shows the temperature is 25°C, when people connect a nominal 1600W laser chiller to a 75W semiconductor engraver machine. While the laser engraver machine is very hot, it illustrates that the laser chiller does not play cooling affect.

What are the consequences of the low water head of the chiller pump?

It is very easy to cause the laser module and Q head to have poor heat dissipation. If the water head of the laser chiller pump is too low. It is also very easy to cause dirty plugging. Which will directly affects the performance and service life of the laser. A chiller water pump with low water head are basically without water filter. That will leads to a more smaller water flow or even the water chiller can not operate normally. Since the filter has a certain resistance.

Motorcycle electric water pump is a kind of automotive electric water pump. It built by a brushless dc motor and powered by battery in motorcycle. Its main function is to circulate the coolant to cool the motorcycle's engine or batteries in electric motorcycle.

Motorcycle electric water pump has the advantages of long in life, high in efficiency and precise in control, etc. Therefore, its widely used in high power fuel motorcycle for engine cooling and in electric motorcycle for battery cooling. As a electric coolant pump, its controller can precisely control the work speed of the pump and effectively reduces the loss of output power. The control system can adjust the circulation speed of the coolant through control the pump work speed at any time. Depending on the operation of the motorcycle engine. The pump circulates the coolant inside the engine itself in a low speed, when the engine temperature is low. While it fast circulates the coolant between the engine and the radiator, when the motorcycle engine temperature is high.

Electric Coolant Pump

What hazard are there to the engine caused by the damage of the engine coolant pump?

To put it simply, the automobile mainly relies on the small electric water pump to circulate the water to cool the system, when it is running.  However, the main water pump will stop working, after the vehicle stopped. If there is a problem with the auxiliary electric coolant pump, the turbocharger will not be cooled. It will lead to the reducing in the life of the turbocharger. In addition, the water vapor in the auxiliary coolant pump may cause a short circuit in its control circuit. This will cause too high temperature of the engine coolant pump and erode the related parts. In severe cases, the engine compartment may be ignited or spontaneously ignited, exist a certain security risk.

How to judge the automotive coolant pump is damaged or not?

1. 1. Idle speed is unstable: the failure of the electric coolant pump can lead to the rotation resistance increased. Since the coolant pump connects with the timing belt, the increase of the rotation resistance of the coolant pump can directly affect the rotation of the engine. It manifests the pulsation of the speed after starting, when in idling. Which is more obvious in winter and can even cause the engine flameout.
   3. Noise of the engine area: This sound is a rotating friction sound, similar to the sound of buzzing sound. This kind of sound will accelerate with the rotation of the engine. The changes in the volume of the sound happens, this noise is more and more obvious along with the fault increased.
   5. The engine water temperature is unstable: It manifested, the engine water temperature indicator needle fluctuates within a certain range. The reason is that the water temperature in the small cycle is inconsistent due to lacking of circulation. On the one hand, it lead to the open temperature of the thermostat rose. On the other hand, the low temperature water quickly flows to the thermostat, after the high temperature water flows out. So that close the thermostat quickly.

In general, the engine-assisted electric coolant pump can effectively reduce the temperature after the turbocharged engine is stopped. It is a good protection for the engine. Suggest deal with it in time to avoid bigger problems, when you find a problem with the vehicle cooling system.

The invention of the dishwasher has a long history, it liberates the user’s hands from the housework of washing dishes. With the improvement of people’s living standards, more and more families have demand for dishwashers, especially in recent years, dishwashers have quietly emerged in the world market. Dishwasher water pump, as well as dishwasher drain pump, are indispensable as a core function in the dishwasher.

So, what is a dishwasher water pump?

Dishwasher water pump is a centrifugal water pump that uses the centrifugal water pressure generated by the high-speed rotating impeller, to spray the water which in the tank through the spray arm hole to clean the bowl and the dish. It usually install at the bottom of the dishwasher tank. And people divide it into AC dishwasher pump and DC dishwasher water pump according to the motor supply voltage form.

How to choose a right dishwasher pump?

A good dishwasher needs to use a good dishwasher pump to achieve a satisfactory dishwashing effect. So, what kind of pump is better for applying in the dishwasher ? and how to choose a most suitable dishwasher water pump for your dishwasher ? You can follow the below suggestions:

1. Work Voltage

3.  

   The dishwasher is a machine that washes the dishes with water, the voltage safety of the dishwasher should be considered. It may cause a high safe issue to user once the voltage is leaking, if use high AC voltage to drive the dishwasher pump. So, it is recommend to use DC voltage that is lower than the human body safety to driven the DC dishwasher pump motor. Generally speaking, it is usually use not more than DC 24V voltage to drive the DC low-voltage pumps. Thus , it does not harm to personal safety even if voltage leaking happens. So there is no safety hazard with the dishwasher .

5. Pump Material

   It need use food grade materials to produce the parts of the dishwasher pump which direct contact with water.So, a dishwasher pump should be a food grade pump. Its materials must meet certain food safety requirements to ensure that they are not harmful to the user’s health.

7. Dishwasher water pump Water head

   Dishwashing requires not only moderate flow, but also a certain water flow impact. Therefore, it requires a high water head pump that spray out water with large impact force. So that, it can rinse clean the tableware. Recommend people use dishwasher water pumps with water head more than 5 meter.

9. Water flow

   It need to choose a dishwasher pump with a large flow rate not less than 55L/min. The more large water flow is, the more big rocker arm of the dishwasher can be chose. And large amount water can flow out from the dishwasher , So that, dishwasher can wash the dishes more at a time.

11. Pump Power

    Recommend people to choose a dishwasher pump with power lower not more than 40w. Since, the more smaller the pump motor power is, the more smaller power consumption is. And the more energy-saving the dishwasher is.

13. Work Noise

    Recommend to choose a quiet water pump with a noise not higher than 45 dB. The smaller work sound of the pump is, the less noise will be produced when the dishwasher is working, else it may bring the user with a bad experience. Therefore, the noise level of the dishwasher pump is a key indicator for measuring the performance of the dishwasher.

15. Stability performance

    Recommend to select a the pump with constant power.  So that, the dishwasher water pump can run at full capacity , regardless of no matter what voltage is input. Thus the performance of the dishwasher is stable.

17. Life span

    The dishwasher is a machine that people turn on frequently. Usually operate dishwasher water pump for two times for three meals a day. So, there are four times for the pump starting and stopping. In general, the pump will generate a large current to impact the motor during start-stop. Which will undoubtedly reduce the service life of the pump, resulting in a decline in the quality of the dishwasher. There will be no such problem, if you choose a soft start pump . The soft start pump current is a gradually increasing process, and there is basically no damage to the motor itself. In addition, brushed DC pump generally use a life of only a few thousand hours a year. While brushless dc pump can use more than 15,000 hours, so it is recommended to choose a brushless DC motor dishwasher water pump.

As we all know, CPU generates a lot of heat during work. The “electron migration phenomenon” will destroy the chip internal organization of the CPU. And cause permanent damage to the CPU, if the heat cannot be dissipated in time. Therefore, the computer needs to dissipate heat. Common computer cooling method includes air-cooled, and water-cooled, oil cooling, liquid nitrogen etc. Among of which water circulation heat dissipation by using a PC water cooling pump is the main form of water-cooled.

So, what is a PC water cooling pump ?

PC water cooling pump also named pc water pump. It usually refers to a centrifugal pump that use centrifugal force generated by the rotation of it’s impeller to circulate the water and cool the CPU. Therefore, you can also call it cpu water cooling pump, cpu water pump. The computer water pump is a quiet water pump mainly composed of control circuit, pump chamber, rotor, pump cover, and pump casing. It has characteristics of high stability, long life and low noise etc.

How to choose a pc water cooling pump ?

People should take below lists performance into consideration when choose a pc water pump for their PC water-cooled system.

1. Stability

   As a small circulation water pump, computer water pump is the heart of the computer water cooling system. Its stability determines whether the water cooling system can run normally or not. Congratulations, if the water pump damaged when runs, your hardware like boiling water soup , you can boil the eggs for breakfast 10 minutes later. Therefore, the stability of the pump is the most important to a pc water pump.

3. Life span

   Generally speaking, the life span for a PC water cooling pump should be more than 15,000 hours in general market. Since pump is an electronic product, there will always be aging phenomenon. It will cost a lot of money if it’s life span is too short, which is not worth the loss for a water-cooled player. Here, suggest you choose a quiet brushless dc pump as a computer water pump serve for your computer water cooling system, since a pump driven by a brushless dc pump motor usually with life span more than 20,000 hours.

5. PC water pump Water Head

   The water head refers to how height the pump can lift the water. The waterways in the water cooling system are not all straight lines, there are other angles. These angles brings certain resistance for the water flow. So, water pressure loses happens when the water flows to these angles. It will cause the water unable to flow if the pump’s head is too low. In other words, like a car climbs the slope, it will make the car squat if the throttle is not enough. So the water head is a key performance requirement in the water cooling system. In the conventional computer water cooling system, the requirements for the water head of a PC cooling water pump are between 2 meters and 6 meters.

7. Water Flow

9.  

   Water flow refers to the total amount of water delivered by the PC water cooling pump in a unit of time. The general statement is how many liters of water a pump can transport in an hour. The water in the water pipe will not be able to fully occupy the inner diameter of the entire water pipe,if the flow rate is insufficient. In this case, the liquid that can supply the main part such as the cold head is insufficient, and the heat of the CPU cannot be quickly taken away. Not to mention it can cool the CPU and the graphics card. So,the flow rate requirement in a conventional PC pump water cooling system, should be within the range of 300L/hour~1000L/hour.

11. Noise value

12.  

    It is better to use a wind-cooled rather than a water-cooled if the latter cool way is not so quiet. Work noise is another important parameter for a PC water cooling pump. We should take noise  into consideration when use water-cooled. Generally speaking, it is a a quiet water pump if its work noise is below 25dB. And it is very hard for people to hear the pump work noise if he stay half a meter away from the computer.

Quiet water pump refers to a 12v or 24v circulation water pump with very low noise, we can also call them silent water pump. The noise of silent water pump generally reaches below 30dB, and some ultra quiet water pumps even reach below 23dB. Pump noise is not only the noise generated by the work of the motor, but also the noise generated by the water flow friction between the water and the pipe wall. However, all of the above 2 kinds of noise is basically can be negligible for a silent water pump .

Therefore, quiet water pump usually can be seen in the environmental protection medical industry and in the research laboratory. They are small in size, low in noise, and low in power consumption, is a green and environmentally friendly machine. Silent water pump are widely used in medical, indoor, aquarium, shower, hot water mattress, aquarium, fountain, as well as home, kitchen, bathroom appliances’s water booster, water circulation.

Why should people use quiet water pump?

The biggest characteristic of pump noise pollution is sensory pollution, which affects people's work, rest and sleep, and thus endangers human health. At the same time, the pump noise has a strong penetrating power. Like the ordinary load-bearing wall of a general building, the pump noise can easily penetrate. Therefore, the impact of pump noise on the human body is very large, such as the insomnia, increased blood pressure, and corresponding neurological diseases etc. For fish tank, fish lovers should use a quiet aquarium water pump for heir beloved fish to have a quiet and clean aquarium environment. Otherwise, it will impact the fishes life span a lot if let them live in a big noise environment for a long term period.

It can be seen that the noise of the pump is likely to seriously affect people's physical and mental health and quality of life. It is easy to get irritated, inattention, memory loss, insomnia and other neurological diseases, which need to attract enough attention from the people.

Therefore, people must consider a quiet pump with very low noise when they are buying and using pumps in indoor, kitchen, sanitary, industrial places, etc. Such as: plumbing mattress, coffee machine, PC water cooling pump, kitchen and intelligent toilet water pump, aquarium pumps, quiet shower pump, etc.

What reasons cause a silent pump to generate big noise after operating for a period of time?

Not everyone knows what reasons cause it, if a big noise generated when we run a quiet water pump. Now we can help you carefully analyze the following possible factors:

• 1. The bearing clearance becomes larger and the noise increases a lot after the pump using for a period of time.
• 2. The shaft inside the pump is not pressed into place.
• 3. Noise caused by loose ceramic gaskets.
• 4. The air in the pump is not completely discharged that causing the rotor do not closely match with the pump head, and the impact of the jump the gasket  then the noise is generated.
• 5. The pump impeller is unbalanced and the noise is increased.due to cavitation or scale。
• 6. There is foreign matter entering the inside of the pump body,  resulting in unbalanced pump operation and increased noise.
• 7. The noise generated by the vibration of the pump itself during operation;
• 8. The pump is damaged, and the parts on the rotor are rubbed against the pump body;
• 9. The noise generated by the water flow of the pump increases the sound level of the noise ,if it deviates from the design condition.

How to solve the big noise problem ?

• 1. The internal problem of quiet water pump, take the pump in the hand and hang it in the fish tank water then run it. Disassemble the pump and reinstall the rotor and impeller if the sound is still big.
• 2. Move the pump or pipe so that it is not in direct contact to solve the cylinder wall formed by the pump or pipe hits the resonance.
• 3.The external problem of the pump, put a cotton on the bottom of the pump or put filter cotton on the base cabinet can reduce noise.
• 4. Install a vibration isolator on the water pump to isolate vibration and solid sound propagation to improve vibration isolation efficiency;
• 5. In order to prevent the heat pump from dissipating a large amount and causing a malfunction add a soundproof cover to the water pump. The exhaust fan in the cover is used as a forced ventilation, and installs an in-and-out silencer at the same time;
• 6. Check the bearing of the water pump and the rotor of the water pump. Replace them if the bearing and the pump blade are worn out.
• 7. Run the silent water pump under design conditions.

People pay more and more attention to food safety, with the improvement of people’s living standards. That, makes food grade pumps are widely used in kitchen beverage appliances, as well as food, medicine and other manufacturing industries.

So, what is a food grade pump?

Food grade pump also named food safe pump. It is a type of circulation water pump whose components that direct contact with working fluid such as food, beverages, drinking water, are made by food grade materials. Its materials must meet certain food safety requirements to ensure that they are not harmful to consumer health. Food grade water pump is suitable for transferring food, beverages, and drinking water for coffer maker, water dispenser, beverage machine, brewing equipment, etc. It is an indispensable conveying equipment for food, chemical, pharmaceutical and other industries.

How to clean a food grade pump ?

Cleaning project

1. Scrape off the scale and rust accumulated in the inner and outer surfaces of the impeller,seal ring and bearings, and then clean it with water.
2. Clean the grease and rust accumulated on the joint surfaces of the casing.
3. Clean the water seal tube and then check to see whether it is blocked or not.
4. Remove the grease, cean the bearing bush and bearings, then clean the oil ring and oil level gauge. Ball bearings should be cleaned by gasoline.
5. Components of the food grade water pump that are not assembled for the time being, should be oiled after cleaning.

Cleaning Principle

1. For sprayed, plated, bonded workpiece surfaces, the cleaning requirements are high. Different cleaning agents and cleaning method must be used according to different requirements during cleaning to guarantee the required cleaning quality.
2. Prevent corrosion of components and any degree of corrosion on precision parts is not allowed. Consider the anti-rust ability of the cleaning solution or consider other anti-rust measures, when the parts need to be parked for a period of time after cleaning.
3. Ensure safe operation,prevent fire harm the human body and pollute the environment.
