Q:What is the pump lift voltage? And how to suppress the pumping voltage rise?
The reverse voltage and torque electric torque instead, and the motor has strong braking torque, forcing the rotor quickly stopped, but usually AC-DC-AC converter is the main power AC/DC rectifier circuit is irreversible, and therefore can not return to the power grid, resulting in the main circuit of the capacitor voltage increases two that is called the pump voltage.
Q:What is an industrial water pump?
Industrial water pump, water pump for industrial production.A pump is a machine that transports liquids or pumps liquids. It will be the prime mover of the mechanical energy or other external energy transfer to the liquid, the liquid energy increase, mainly used to transport liquids including water, oil, alkali liquid, emulsion, suspension emulsion and liquid metal, but also transport liquid, gas mixtures and liquids containing suspended solids. 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.
Q:How do vacuum pumps and pumps work together?
The role of the check valve:"[the water pump impeller is not closed" refers to the pump suction pump before the water without water inlet pipe and water outlet pipe gas should be connected] is a connector, a connector, still can make the level surface, in order to prevent the water flow along the pipe, until it reaches the level of the flush, then increased check valve.
Q:Does vacuum pump oil belong to dangerous goods?
Is the grease inside? How could it be dangerous goods? Absolutely not!
Q:What is the displacement of the pump? Flow? What is the volume efficiency and mechanical efficiency of the pump?
Displacement of a pump: the volume of the discharged liquid calculated by the change in the size of the sealing geometry for each revolution of the hydraulic pump
Q:Household automatic booster pump, how much pressure can you work automatically?
With the pressure does not matter, because the pressure is small, it is necessary to boost the pump, the water pressure with the pipe flow and the size of the booster pump related
Q:The suction pump has a nominal suction range of 30 metersHow deep can a well be sucked?Well, sixteen meters,
Vacuum pump plus form must not reach a standard atmospheric pressure vacuum, so the general can absorb 8 meters is very good, and the self suction pump itself and loss, the horizontal self-priming pump can suck on basic 4~6 meters is very good, self-priming pump. Suction lift of 30 meters is purely in the Mongolian people, does not comply with the laws of nature, obvious anti science.
Q:Water pump does not produce water, what are the reasons?
The reason why centrifugal pump does not produce water:1. pump inlet or sink, water tank water shortage.2. water pump pipe blocked or valve not open.
Q:What are the problems that should be paid attention to when using vacuum pumps?
(1) check the vacuum pump line and the joint site regularly to see if there is any looseness. Turn the vacuum pump by hand and see if the vacuum pump is flexible.(2) add lubricating oil to the bearing body, observe the oil level at the center line of the oil mark, and the lubricant shall be replaced or supplemented in time.(3) plug screw vacuum pump of the water screw, filling water (or lead paste). (4) turn off the gate valve of the water outlet pipe and the outlet pressure gauge and the vacuum gauge. (5) point motor, and see if motor steering is correct.(6) start the motor. When the vacuum pump is in normal operation, open the outlet pressure gauge and the inlet vacuum pump. As soon as the proper pressure is shown, the gate valve is gradually opened, and the motor load is checked.
Q:What is the Rhodes pump?
Work principle editorRoots-type pump is a vacuum pump without internal compression, usually compression ratio is very low, so high and medium vacuum pumps need pre pump.A vacuum pump for pumping air by pumping a gas by the simultaneous rotation of a pair of lobed rotors in a pump cavity and a reverse rotation.Roots vacuum pump is a mechanical vacuum pump with a pair of synchronous and high-speed rotating sole shaped rotors. The pump can not be drawn out separately. The front stage needs to be equipped with an oil seal and a water ring, etc. it can be discharged directly into the atmosphere.
