Q: Rotary vacuum pump does not meet the requirements of vacuum, what are the reasons?: 1) oil rotary vane vacuum pump is too low, no effect on the oil seal exhaust valve, rotary plug to refuel after large exhaust sound, and oil mist, that the level is too low, the gas can be eliminated.(2) the vacuum caused by the condensable steam pollution of oil should be changed, and new vacuum pump oil should be replaced.

Q: What are the general water pump failure, how to repair?: (4) because of the long latent water and the corrosion of the pipe wall, the water inlet of the water inlet is constantly dropping. When the holes appear above the water, the air enters the water inlet pipe from the hole.(5) there is a crack at the bend of the inlet pipe, and there is a small gap between the inlet pipe and the water pump, which may cause the air to enter the inlet pipe.

Q: What is a solution pump?: 2.1 advantages of canned pumps(1) fully enclosed. There is no dynamic seal in the structure. Only the static seal in the outer shell of the pump can be made without leakage. It is especially suitable for transporting flammable, explosive, precious liquids and toxic, corrosive and radioactive liquids(2) high safety. The rotor and stator each have a shielding sleeve, so that the rotor and stator of the motor are not in contact with the material, even if the shield is broken, it will not produce the risk of leakage and leakage(3) compact structure and small footprint, the pump and motor is a whole, disassembly and assembly do not need to find the center. The base and foundation requirements are low, and the daily maintenance workload is low, and the maintenance cost is low

Q: What are the advantages and disadvantages of the pump control system and valve control system in the hydraulic system? How to choose in the project?: Valve control system is generally used for open systems, through the proportional valve or servo valve flow changes to control the motor or cylinder actuator action. The advantages of the system are energy saving, heat generation, and control accuracy. The disadvantage is that the system is complex and the cost is higher.

Q: What are the ways of hydraulic pumps?: Check valves, such as single piston pumps, three piston pumps, etc.;The port of the valve arrangement, such as the radial piston pump.

Q: Rules for operation of centrifugal pumps: 3, start the pump, wait until the speed reaches the normal speed, slowly open the outlet valve, observe the ammeter at the same time, and control the current in the rated current range of the motor.4, the operation requires smooth operation of water pumps, no abnormal noise, no pressure fluctuations. The abnormal situation should be stopped in time.

Q: Direct connection pump What is straight pump and non direct pump? What's the difference in structure?: What is straight pump and non direct pump? Direct coupled pump shaft and the motor shaft is directly coupled with the coupling and non direct coupled pump: pump shaft and motor shaft through the belt pulley, V-belt connection or other forms of transmission. What is the difference in the structure: the direct coupled pump has the advantages of compact structure, simple installation, but the relatively small power; non direct coupled pump: pump and motor is independent, the two transfer torque through the belt, the structure is relatively large, complex installation, general power is relatively large.

Q: What is the nominal pressure of the hydraulic pump and hydraulic motor?: Related concepts of hydraulic motorsFlow theoretical volume refers to the volume of oil inhaled in unit time without leakage.

Q: Which nuclear submarines use the shaftless pump technology?: Shaftless pumping technology and Simulation of shark skin technology are all the next generation of submarine propulsion technology. At present, there is no submarine in the world.

Q: What is the difference between centrifugal pump and self suction pump? Which is better?: In order to prevent the filling liquid into the pump shell because of gravity flow in the low groove, in the pump suction pipe at the entrance of a non-return valve (valve); if the location of the pump below the liquid level in the tank, then start without irrigation pump.Self-priming pump is a self-priming centrifugal pump, centrifugal pump is a kind of.Specific choice of a pump, depending on your specific parameters and conditions of use.
