Q:Attention should be paid to the use of pumps?
1, pump shaft packing completely worn, it is necessary to add in time, if you continue to use the water pump will leak. The direct effect of this is the increased energy consumption of the motor, which will damage the impeller. 2, the use of pumps in the course of a strong vibration, then must stop to check the reasons, or the same will cause damage to the water pump. 3 gear pump valve Water Leakage, some will use the soil into the water pump inlet tube, the water washed in the end valve, this is indeed undesirable. Because when the dry soil into the inlet pipe, when the pump started working, these dry soil will enter the pump, which will damage the pump impeller and bearings, which shorten the service life of the pump. When the valve Water Leakage must take to repair, if it is serious that it is necessary to replace the new. 4 after the use of pumps must pay attention to maintenance, for example, when the pump is exhausted, we should put the water pump who put clean, it is best to remove the water pipe, and then rinse with water. 5 water pump on the tape should also be written down, and then always flush, and then light out to dry, do not put the tape in the dark damp place. Water pump tape must not be stained with oil, not to tape coated with some sticky things.
Q:What are the failures and causes of the replacement of the fuel pump assembly?
Gasoline pump is the gasoline from the gasoline tank suction and the gasoline tank has a certain pressure, thereby, it overcome the resistance of the pipeline, pipeline and fuel filter into the carburetor float chamber or electronically controlled injection engine in the guide frame.
Q:What is the series of pumps? What's the difference between a unipolar and a multistage?
Each impeller is of the first stage. (two impellers share only one level, and exit is only level one)
Q:What does the impeller on the centrifugal pump mean by the first cutting?
I used to do this job before. After the impeller is cut, the flow and lift will decrease. Sometimes, the same pump will be cut according to the needs of the impeller, so as to meet the actual needs, at this time, with the power of the motor will also be reduced
Q:Is the flow meter in front of the pump or after the pump?
After the flowmeter is placed in the pump, it is better to add a pressure tank or a buffer tank, so that the flow meter will work better
Q:The working principle of magnetic pump
Control of cooling fluid flowThe pump is running, you must use a small amount of liquid in the magnetic separation between the rotor and the casing annulus area and sliding friction bearings for flushing cooling. The cooling liquid flow pump design flow is usually 2%-3%, the annular area between the magnetic rotor and sleeve of eddy current generated because of high heat. When the cooling and lubrication the liquid is not enough or poor flushing holes to plug, will result in permanent magnet medium temperature is higher than the operating temperature of the inner magnetic rotor gradually loses magnetism, the magnetic actuator failure. When the medium is water or water-based liquid, can make the annulus area temperature maintained at 3-5 DEG C; when the medium or hydrocarbon oil that can make the annulus area temperature maintained at 5-8 degrees.
Q:Centrifugal pumps for normal operation, is it reasonable to install valves on their inlet lines?
Unreasonable, easy to produce throttling loss, pressure loss, pressure reduction, easy to cause cavitation
Q:How to calculate the motor power of metering pump?
The motor power of the metering pump is divided into two parts1. mechanical power, this part of the power metering pump design part will be some data, mainly to control the mechanical structure of the metering pump required power
Q:What is the distance between the pump and the wall?
What do you mean by that? If your pump is parallel to the wall! Then, the wall of the pump near the wall is usually 500mm. This is an empirical data, considering the import pipe length, pump maintenance and motor heat dissipation and other aspects of the situation to determine. Dozens of pumps installed in our company are placed in this size! Hope to be of help to you.
Q:Know flow and lift how to calculate the pump power?
P: the density of refrigerant, when the working fluid is water, P =1ETA - pump efficiency, can not find desirable value =0.8N=30x (200/3600) x9.81x1/0.8=20.44 = 20 (kW)(that is, 20kW motors)
