Q: How about the depreciation of vacuum pumps?: (a) housing and buildings for 20 years;(two) aircraft, trains, ships, machinery, machinery and other production equipment for 10 years;

Q: Is the vacuum pump air compressor?: No, both work in the opposite way. Air compressor, referred to as an air compressor, is a machine that produces compressed air (positive pressure). The vacuum pump is just the opposite.

Q: Why can't the inlet of centrifugal pump be negative pressure?: Can be negative pressure ah, the negative pressure here refers to the pressure is less than the atmospheric pressure, but the pressure can not be too low, to prevent water vapor below the saturated vapor pressure, so that water vaporization, cavitation phenomenon, the centrifugal pump will be considered.

Q: Why can the centrifugal pump hold down the pressure?: Centrifugal pumps are vertical, horizontal, single-stage, multi-stage, single suction, double suction, self suction and other forms. Vertical centrifugal pump is referred to as submerged pump, molten salt pump and submerged pump. Centrifugal pumps use the impeller to rotate and cause centrifugal motion of the water to work.

Q: Brief description of centrifugal pump on / off operation: (3) check whether the turning rotor is easy and flexible, check the pump body is clang or friction sound.(4) the protective cover is installed, and the shield contact.(5) clean the pump frame and do a good job of sanitation.(6) open the inlet valve, make the liquid full of pump body, open the vent valve, clean the air and close it. If the hot oil pump, it is not allowed to open the air valve exhaust, to prevent hot oil channeling spontaneous combustion, if there is a dedicated vent pipes and tanks, you can vent the pipe line air and cold oil.(7) the hot oil pump should be preheated slowly before starting. Especially in winter, the pump body and the pipe should be preheated at the same time, so that the temperature difference between the pump body and the conveying medium is below 50 centigrade.(8) the oil must be sufficiently dehydrated before being introduced into the oil pump.

Q: The main factors affecting the performance of centrifugal pumps: The specific speed is deduced by the law of hydraulic similarity, and the similarity between the hydraulic characteristics of centrifugal pumps is similar. In centrifugal pumps, the specific speed is often interpreted as: the pump works at the highest efficiency, generating a lift of LM, a flow rate of 0.075m, and the power consumed by the /s at 0. 735kW

Q: How many kilograms of water pump are there in the automatic washing machine on the market?: Longer service life. Automatic switch water pump, car wash automatically open and stop, easy to operate, not easy to bad, repair rate is low!!!

Q: What is the difference between centrifugal pump and rotary vane pump? What are the distinctive characteristics or principles of rotary and centrifugal? O (a _ U) O thank you!: This is a classification problem.Rotary is classified by movement, vane pumps are rotary, volumetric pumps are mostly rotary, piston pumps, etc., is reciprocating.

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: 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
