Q: What are the uses and precautions of magnetic pumps?: Installation and use of magnetic pumps:1, the magnetic pump should be installed horizontally, should not be erected, the plastic pump body can not bear the weight of the pipeline, for the special requirements of vertical installation occasions, the motor must be facing up;

Q: What does "anti pump" mean in pump operation?: The working process of the main oil cylinder pushing back and forth against the pump when the S valve (C valve or valve or gate valve skirt) reverse swing, so the piston suction concrete cylinder is in the ash conveying pipe is exactly opposite is the pump suction pump (hopper is concrete and push into the hopper, the desizing)

Q: The difference between diaphragm pumps, vacuum pumps and centrifugal pumps: The function of vacuum pump is to make vacuum, which has many kinds of structure, such as centrifugal, diaphragm (diaphragm), piston, liquid ring, rotary plate, jet type...................

Q: Why does the centrifugal pump start and close first when the outlet valve is closed?: The operation rules of centrifugal pump strictly required to close the outlet valve before the shutdown, boot and then slowly open the outlet valve, regulating pipeline pressure and current range. The reason is: the centrifugal pump in the startup process in order to avoid large starting current caused by electrical faults, such as circuit breaker tripping,

Q: Is vane pump good or gear pump good?: 1) the reversible design of gear pumps can also usually reverse, but reverse after the suction port change, and the pump safety valve does not work; leaf pump is generally not allowed to reverse. 3) the single acting vane pump can be designed to change the eccentric distance by moving the stator at the constant speed, so as to achieve the purpose of variable direction.

Q: What are the problems that should be paid attention to when using vacuum pumps?: (14) vacuum pump used in the winter season, after stopping the pump body, lower drain plug unscrew medium on the net. To prevent cracking.(15) the vacuum pump has been disabled for a long time. All the pumps should be taken apart and dried. The rotating parts and the joint should be coated with grease and properly preserved.

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: Which nuclear submarines use the shaftless pump technology?: The team led by academician Ma Weiming of China is now carrying out the research on this technology and has achieved initial success.. This technology is expected to be applied to the next generation of domestic submarines.

Q: Do you have a suction pump higher than 9 meters?: Since the atmospheric pressure has been basically determined, the theoretical suction degree of the pump is more than 10 meters.

Q: What is the difference between an air pump and a water pump?: Pump performance of technical parameters are flow, suction, lift, shaft power, water power, efficiency, etc.; according to the different principles of work can be divided into volume pumps, vane pumps and other types. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.
