What is water pump?

Published:2019-07-18

Water pump is a machine that circulates or boosts liquid,the technical parameters to measure the performance of water pump are flow, suction, head, shaft power, water power, efficiency and so on. According to different working principles, it can be divided into volume water pump, vane water pump and so on. Volume water pump uses the change of studio volume to transfer energy. Vane pump uses the interaction between rotating vane and water to transfer energy, including centrifugal pump, axial flow pump and mixed flow pump and so on. According to the control principle, centrifugal pump can be divided into AC pump, brush DC pump, brushless DC motor pump and brushless DC magnetic isolation water pump.

 

Water pump field of application:

Shenpeng provide dc mini water pumps, which can be used for computer cooling system, coffee machine, water purifier, soilless culture, water heater, warm mattress, chiller machine, dishwasher, Intelligent toilet, new energy vehicle cooling system, and so on.

Installation method of water pump


1. The water pump shall be close to the water source as far as possible to reduce the length of the suction pipe under the conditions of geographical environment. The foundation at the pump installation site shall be firm, and the fixed pump station shall be built with special foundation.


2. The water inlet pipe shall be sealed reliably and must have special support. It cannot be hung on the water pump. The inlet pipe with bottom valve shall be installed vertically with its axis and horizontal plane as far as possible, and the included angle between its axis and horizontal plane shall not be less than 45 °. When the water source is a channel, the bottom valve should be more than 0.50 meters above the bottom of the water, and the screen should be added to prevent sundries from entering the pump.


3. The base of the machine and pump shall be horizontal and firmly connected with the foundation. When the machine and pump are driven by belt, the tight side of the belt is lower, so the transmission efficiency is high. The direction of the pump impeller should be consistent with the direction indicated by the arrow; When coupling transmission is adopted, the machine and pump must be coaxial.


4. The installation position of the water pump shall meet the requirements of the allowable vacuum suction height, and the foundation must be horizontal and stable to ensure that the rotating direction of the power machinery is consistent with that of the water pump.


5. If there are multiple units in the same machine room, there should be a distance of more than 800mm between the units and between the units and the wall.


6. The suction pipe of the water pump must be well sealed, and the elbows and gate valves should be minimized. When filling water, the air should be exhausted. During operation, the air should not be accumulated in the pipe. The suction pipe is required to be connected with the water inlet of the water pump in a slightly upward slope, and the water inlet should have a certain submergence depth.



Precautions for water pump


1. If the water pump has any small fault, remember not to let it work. If the packing of the water pump shaft is worn, it should be added in time. If the water pump continues to be used, it will leak. The direct impact of this is that the energy consumption of the motor will increase and the impeller will be damaged.


2. If the pump vibrates strongly during use, stop to check the cause, otherwise it will also cause damage to the pump.


3. When the bottom valve of the water pump leaks, some people will fill the inlet pipe of the water pump with dry soil and flush the bottom valve with water, which is really not advisable. Because when the dry soil is put into the inlet pipe, when the pump starts to work, the dry soil will enter the pump, and then the pump impeller and bearing will be damaged, which shortens the service life of the pump. When the bottom valve leaks, it must be repaired. If it is serious, it needs to be replaced.


4. Pay attention to the maintenance of the water pump after use. For example, when the water pump is used up, the water in the water pump should be cleaned. It is better to remove the water pipe and wash it with clean water.


5. The adhesive tape on the water pump should also be removed, and then washed with water and dried in the light place. Do not put the adhesive tape in a dark and wet place. The adhesive tape of the water pump must not be stained with oil, let alone some sticky things on the adhesive tape.


6. Carefully check whether there are cracks on the impeller and whether the impeller is loose on the bearing. If there are cracks and looseness, repair it in time. If there is mud on the pump impeller, clean it up.
