There are two reasons why the pump can not supply water:

1

The centrifugal speed of metering diaphragm pump is too low

5. There are several reasons why the water pump does not supply water.
first, there is air in the water inlet pipe and pump body of the pump.
(1) before the pump starts, it is not filled with enough water, sometimes it seems that the water has overflowed from the vent hole, but the air is completely discharged without rotating the pump shaft, resulting in a little air remaining in the water inlet pipe or pump body
(2) the horizontal section of the water inlet pipe in contact with the water pump should have a descending slope of more than 0.5% in the reverse flow direction, and the end connecting the water pump inlet should be the highest, not completely horizontal. If it is tilted upward, air will remain in the water inlet pipe, which reces the vacuum degree in the water pipe and water pump and affects the water absorption
(3) e to long-term use, the packing of the pump has been worn or the packing has been pressed too loose, resulting in a large amount of water ejecting from the gap between the packing and the pump shaft sleeve. As a result, the external air enters into the pump from these gaps, affecting the water lifting. The mechanical seal of the pump with mechanical seal is damaged and leaked
(4) e to the long-term potential underwater corrosion, the water surface of the water inlet pipe decreases continuously after the pump works. When these holes come out of the water, the air enters into the water inlet pipe through the holes
(5) cracks at the elbow of the water inlet pipe and tiny gaps at the connection between the water inlet pipe and the water pump may cause air to enter the water inlet pipe< (1) human factors. Due to the damage of the original motor, some users randomly equipped with another motor to drive, resulting in small flow, low lift and even no water supply
(2) mechanical failure of the pump itself. If the fastening nut of impeller and pump shaft is loose or the pump shaft is deformed and bent, the impeller will move more, directly rub with the pump body, or the bearing will be damaged, which may rece the speed of the pump
(3) the maintenance of the power machine is not effective. The motor loses excitation e to the winding burn out. The change of winding turns, wire diameter and wiring method in maintenance, or the failure not completely eliminated in maintenance, will also change the speed of water pump
thirdly, the suction head of the water pump is too large
some water sources are deep, and some water sources have flat terrain, while the allowable suction head of the water pump is ignored, resulting in less or no water absorption. We should know that there is a limit to the degree of vacuum that can be established at the water inlet of the pump. The suction head of the absolute vacuum is about 10 meters water column high, while the pump cannot establish the absolute vacuum. And the vacuum is too large, easy to make the water in the pump vaporization, adverse to the work of the pump. Therefore, self-priming centrifugal pump has its maximum allowable suction, generally between 3-8.5 meters. The installation of water pump should not be simple and convenient
the suction head of the pump is also related to the inlet and outlet pressure of the pump, and the rection of the pressure will also lead to the self-priming effect of the pump, in which the variable diameter pipe is used at the inlet, and the elbow at the inlet is dense, which will lead to the typical wrong installation< (4) the resistance loss in the water inlet and outlet pipes is too large.
some users have measured that although the vertical distance from the reservoir or water tower to the water surface of the water source is slightly less than the pump head, the water volume is still small or unable to be lifted. The reason is often that the pipe is too long, there are many bends in the pipe, and the resistance loss of water flow in the pipe is too large. The reason is often that the pipe is too long, there are many bends in the pipe, and the resistance loss of water flow in the pipe is too large. In general, the resistance of 90 degree elbow is greater than that of 120 degree elbow. The head loss of each 90 degree elbow is about 0.5-1 m, and the head loss of every 20 m pipe is about 11 M. In addition, some users also arbitrarily pump in and out of the pipe diameter, which also has a certain impact on the head< (1) the filter net of bottom valve is blocked; Or the bottom valve may block the filter screen in the sludge layer in the water
(2) the impeller is seriously worn. The impeller blade is worn after long-term use, which affects the performance of the pump
(3) the failure or blockage of the gate valve and check valve will rece the flow rate or even fail to pump water
(4) the leakage of the outlet pipe will also affect the water extraction
(5) the bottom valve cannot be opened. Usually e to the pump shelving time is too long, the bottom valve gasket is stuck, no gasket bottom valve may rust
(6) the water inlet pipe of the pool and the water inlet pipe of the pump interact with each other to proce cavitation. The water in the water inlet pipe of the pool enters the pool to proce bubbles, which are inhaled by the water inlet pipe of the pump to proce cavitation.

How to solve the problem that the dosing pump can't pump the liquid medicine? Meibao teaches you three tips:

(1) the bottom valve of the dosing pump is blocked by sundries. This is the most common situation. It's also very simple to encounter this problem. As long as the bottom valve is cleaned, you can pump the liquid medicine

(2) there is air at the inlet end of the dosing pump, which may be caused by the blockage of foreign matters in the bottom valve, so that the liquid medicine can not be sucked in and the air runs in. It may also be caused by the poor air tightness of the inlet. If it is the first case, after cleaning the bottom valve, it may be necessary to fill the pipe and dosing pump with water and liquid at the inlet of dosing metering pump before it can be used again. In the second case, it is necessary to check the air tightness of each interface position at the water inlet end and re seal and tighten it

(3) when the liquid level of the dosing pump is reced to a certain extent, it can not absorb water. This problem needs to consider whether the pipe installation at the inlet end of the dosing pump is too long and the suction head of the dosing pump is not enough; Or the air tightness of the inlet is not good, resulting in the drop of the liquid level, the liquid medicine in the pipe at the inlet end also drops with the liquid level, and finally cannot absorb water. If it is caused by the suction head, it is necessary to change the installation position of the dosing pump or replace the dosing pump with high suction head; If it is because of poor air tightness, it is necessary to tighten all parts of the water inlet end of the dosing pump, and check whether the bottom valve is normal

A good pump has no suction. The possible problems are as follows:

1. The pump is not full of water and there is air

The water inlet or water inlet pipe is blocked

3. Air leakage of water inlet pipe or instrument

4. The pump bottom valve is not opened or stuck, and the water can't come in

The pumping height is higher than the pump down head

5. The motor reverses and the impeller reverses

6

The impeller was damaged

8, the impeller does not rotate, and the impeller loses power (the impeller falls off, the impeller connecting shaft is broken, etc.)

9, the water inlet was not put into the water or the immersion depth of the water absorption part was not enough

extended data:

winter maintenance of water pump:

1. After the water pump is stopped, the remaining water in the water pump and pipeline should be drained, and the external soil should be cleaned, so as to prevent the pump body and water pipe from cracking e to water accumulation and freezing after freezing

2. Iron castings such as bottom valve, bottom valve and elbow of water pump should be cleaned with steel wire brush, and then coated with antirust paint first, and then with paint. After drying, they should be stored in a ventilated and dry place in the machine room or storage room

3. If the belt is driven by belt, the belt shall be cleaned and dried with warm water after unloading, and then hung in a dry place without direct sunlight, and shall not be stored in the place with oil, corrosion and smoke. In any case, Sanchang pump reminds you not to stain the belt with oil substances such as engine oil, diesel or gasoline, and not to apply rosin and other viscous substances

Check the ball bearing, if the inner sleeve is worn, loose, the ball is worn or there are spots on the surface, replace it. The bearings that do not need to be replaced can be cleaned with gasoline or kerosene, coated with butter and reassembled

After the vehicle leaves the scene, the insurance company will no longer claim for the vehicle. The insurance terms provided by the insurance company have blacked out the terms of abandoning the vehicle and leaving the scene, and the corresponding terms are clearly prohibited by law. The above terms have legal effect after the insurance company performs the obligation of prompt

according to Article 70 of the road traffic safety law, if a traffic accident occurs on the road, the vehicle driver shall stop immediately to protect the scene. In the case of having the ability and conditions to inform the insurer without notice, the cause and responsibility of the accident can not be found out, and the insurance company should not bear the compensation liability
