How a Pump Works
The pump is driven by an AC or DC motor
In front of the motor is a valve assembly containing two to five valve pump chambers. Each valve chamber has a diaphragm behind it in the lower pump housing. As the motor shaft turns, an internal cam positioned behind the diaphragms causes the diaphragms to be pushed forward, then back in a continuous sequence creating a suction. As this suction builds, fluid is pulled hrough the inlet, through the various valve chamber check valves to the outlet he volume of flow is determined by several factors including: the number and size of the pump chambers,cam offset, operating pressure, fluid viscosity.
- Q: Rotary vacuum pump does not meet the requirements of vacuum, what are the reasons?
- (1) pump connected outside pipes, containers, pipes, joints and other leakage test instrument, large leakage, rotary gas plug exhaust sound big, and the gas and oil mist discharge, should find leakage cancellation.(2) the assembly of rubber of intake pipe is not proper, damage or aging should be adjusted or replaced.(3) plug hole, the vacuum degree can be decreased, put the oil, remove the tank, loosen the nozzle plate, pull out the oil inlet nozzle, dredge oil hole, try not to use cotton wipe parts.(4) the vacuum system has serious pollution, including containers, pipes and so on. It should be cleaned.(5) the spring of the vane is broken and should be adjusted.
- Q: Why should the pump be closed when the centrifugal pump is started?
- Centrifugal pump has an important characteristic: when the pressure (head) is very low, the flow will be great, which can be seen from the characteristics of the pump curve. While the pump power is directly proportional to the flow rate, pump start, no pressure in the pipeline, caused by the pump flow, high power pump, and the pump motor, the rotating part from rest to high-speed operation, need a lot of acceleration, it will cause a great starting current
- Q: What is a gear pump for?
- Gear oil pump is through a pair of parameters and the same structure of the involute gear of each other rolling meshing, the tank of low pressure oil to work can do the important parts of high pressure oil. A power unit that converts the mechanical energy of an engine into hydraulic energy. The engine is prone to the following faults during its use.
- Q: The function of centrifugal pump
- The basic structure of the centrifugal pump is composed of six parts, namely: impeller, pump body, pump shaft, bearing, sealing ring, stuffing box.1, the impeller is the core part of the centrifugal pump, it is high speed, large output, the impeller blade and play a major role in the impeller before assembly, through the static equilibrium experiment. The inside and outside surfaces of the impeller are required to be smooth, so as to reduce the friction loss of the water flow.
- Q: Why can't the inlet of centrifugal pump be negative pressure?
- Therefore, the centrifugal pump inlet pressure can be negative, and negative number, should be used to pump cavitation margin and liquid saturated steam pressure parameters to specific calculation. Sometimes, the liquid saturated steam conveying pressure is very high, such as the 9 m water column, then the minimum pressure of the pump inlet should be equal to 4+9=13 meters, the atmospheric pressure is higher than 3 meters, not only for negative pressure, even higher than the atmospheric pressure to work properly.
- Q: Why should I pump the pump before starting the centrifugal pump?
- 1., if it is backward flow, it is not pumping;2., if the pump is installed underwater (such as submersible sewage pump), it is not pumping;3. pump is for installation in the form of suction. If no diversion irrigation pump, then the pump is full of air quality, air density is less than water, the pump will not be inside the gas out, the pump pressure will not be far less than the atmospheric pressure, the water will not be pressed into the pump to pump through irrigation formed inside the closed environment, the pump will start water out will cause local vacuum, entrance external water pressure into the pump is in inside and outside differential pressure, complete water movement. (vacuum water diversion is directly through the vacuum pump pumping the air in the pump, resulting in internal and external pressure difference, the external water pressure in the internal and external pressure is press into the inlet of the pump. The principle is the same as the pump. A standard atmosphere of =10m water column.)
- Q: Shielding pump is the main drawback of electricity? How much does it cost more than an ordinary centrifugal pump? Is there any noise in the running of the canned pump? How much is it lower than the noise of the common centrifugal pump?
- The ordinary centrifugal pump is driven by coupling the pump impeller shaft is connected with the motor shaft, the impeller and the motor rotates while working and shielding pump is a kind of non seal pumps, pump and motor is sealed in a medium filled by pumping the pressure vessel, the pressure vessel only static seal and, by a group of wires to provide a rotating magnetic field and rotor drive. The structure eliminates the rotary shaft sealing device of the traditional centrifugal pump, so the utility model can be completely free from leakage.
- Q: Suction stroke and lift of water pump
- Lift pump lift pump can lift refers to the height, usually expressed in H, the unit is m. centrifugal pump lift to the impeller center line, divided by two parts. The vertical height from the pump impeller centerline to the water surface, the water pump to suck water up to the height, called water head, referred to as suction pump impeller; from the center line to the vertical height of the water tank, the water pump can put pressure on the height, called water pressure head, referred to as the pressure. The pump head = + suction head pressure water head should be pointed out that the nameplate marked head refers to the pump itself can produce lift, it is not with the pipe flow friction resistance caused by the loss of lift. In the selection of water pump, attention can not be ignored. Otherwise, will be pumping Sheung Shui.
- Q: No negative pressure water supply equipment, both the main pump and auxiliary pump, power is not the same, how to choose the control cabinet?
- 1) microcomputer frequency conversion control cabinet2) water pump unit3) current stabilizing compensator4) vacuum suppressor5) all kinds of pipe fittings, valves and so on
- Q: How long does the fine stone pump need maintenance? What should I pay attention to?
- Check the line from the relief valve to the cylinder inlet to ensure that there is no external drainage or deformation due to impact and wear and that the connections are complete and fully tightened. - replace any damaged pipe immediately. - change the original settings strictly: all adjustments and calibrations can only be done by professionals. - no fucks hydraulic components, otherwise manufacturers on product warranties and liability shall not be responsible for. A warning because the hydraulic oil can reach very high temperature, there is the danger of burns, so open pipe fittings should take appropriate protective measures. Any replacement parts must conform to the level specified by the manufacturer. 8.2 check lubrication grease pump in oil at any time to ensure adequate and clean the lubrication pipeline joints without overflow phenomenon. Check the lubrication of the running parts at any time, and find the parts which lack oil, and check them immediately to prevent accidents. - check that the centralized lubrication system is effective daily. When the grease pump is empty, the grease added is often not easy to pump out because of the bubble. In this case, open the outlet of the pump, run the grease pump until the grease is re flowing, and then connect the pipe
