- Q: Troubleshooting of diaphragm pump
- The ratio of flow to water weight at a specific weight of --68F. 68F water has a specific gravity of 1Static suction head - the vertical distance from the liquid level to the central line of the pump. The pump shall be above the level of the liquid.Vapor pressure the pressure of all the steam on the free surface of the liquid. In any pump operating system, the operating pressure shall not be lower than the vapor pressure, otherwise the steam will be partially or completely cut off into the pump fluid. Viscosity - because of the presence of friction in the fluid, the property of viscosity gives the fluid resistance to flow.Water hammer action -Water hammer is a sudden power failure, or in the valve closed too fast, due to pressure, flow of inertia, produce water shock waves, like hammer hammer, so called water hammer. The force produced by the flow of water shock waves can sometimes be very large, thereby damaging the valves and pumps. Water hammer effect refers to the inside of the water pipe, the pipe wall is smooth, flow freely. When the opening of the valve suddenly closes, the flow of water to the valve and the tube wall, mainly the valve, will produce a pressure. As the pipe wall is smooth, the subsequent water flow in the role of inertia, the fastest reach the maximum and damage, which is the water conservancy "water hammer effect", that is, "positive water hammer.". This factor should be taken into consideration in the construction of water conservancy pipelines. On the contrary, the valve closed in a sudden opening, it will produce water hammer, called negative water hammer, but also a certain destructive power, but not the former big.. Causes and treatment methods of common failures of diaphragm pumps:
- Q: How does the centrifugal pump pump and cut the pump?
- Check the motor, pump and fasteners in good condition; whether the lubricant is added or not;Disc dynamic coupling, whether or not stuck phenomenon;Open the inlet valve, remove the gas in the pump or pump the gas out of the pump;
- Q: What are the important parameters of the pump?
- The head is the unit weight of liquid pump pumping from the inlet of the pump (pump inlet flange) to the outlet of the pump (pump outlet flange) energy value. Effective energy is a Newtonian liquid through the pump unit is obtained. The N m/N=m, the height of liquid column pumping liquid used, referred to as meters.Speed nThe speed is the number of revolutions per unit time of the pump shaft. It is indicated by the symbol n. The unit is r/min.Cavitation allowance NPSHCavitation margin, also called net positive suction head, is the main parameter to indicate the cavitation performance. The cavitation margin has been expressed by delta H at homePower and efficiencyThe power of water pump usually refers to the input power, that is, the power transferred by the prime mover to the pump shaft, so it is also called shaft power. It is expressed by P;The effective power of the pump, also known as the output power, is expressed in Pe. It is the effective energy obtained by pumping the liquid out of the pump in unit time
- Q: Water pump can not be pumped out, how to maintain water?
- Severe vibration of water pumpIt is possible that the rotor is unbalanced, or the coupling is not good, the bearing is worn and bent, and some parts may be loosened and broken. They can be adjusted, repaired, strengthened or replaced separately.
- Q: Double floor sewage pump circuit diagram of a small problem
- Question 3 when the water level is low, when the 1KA is connected, the pump will run depending on where your SS selector switch is located. Its left and right position, running pump and standby pump definition is different, left position is 1#, running 2# standby, right position is 2# running, 1# standby. Only inIn case the high level switch 2KA is connected, the standby pump may work at the same time.
- Q: What are the starting and stopping procedures for centrifugal pumps?
- Operation method and operation procedure of self-priming centrifugal pumpClick number: 440 release time: 2011-7-24Centrifugal pump method, centrifugal pump operation steps, centrifugal pump use steps
- Q: Why can the centrifugal pump hold down the pressure?
- The pump before starting to pump shell and the water pipe filled with water, and then start the motor, the pump shaft to drive the impeller and water do high-speed rotation, centrifugal water movement, was thrown to the outer edge of the impeller, the pressure water pipeline flow through the volute pump into the pump shell.
- Q: Why is the flow of the pump too small will occur cavitation phenomenon?
- This is because the impeller of the centrifugal pump rotating speed under the drive of the prime mover, when the valve opening decreases, flow rate is too low, can not be taken away by the friction heat generated by the impeller and the liquid completely, make the temperature of the liquid inside the pump. Thus causing liquid vaporization, forming cavitation. Especially in the power plant, the boiler feed pump is more remarkable. Therefore, when throttling regulation, we should set up recirculation system, increase the output flow of the pump to prevent cavitation. When the feed water rate is reduced to 1/3 of the maximum flow rate, the recirculating gate shall be opened so that the flow of the feed pump will be increased properly to ensure that the liquid temperature in the feed pump does not rise.
- Q: What is an industrial water pump?
- The pump has the different uses, conveying different liquid medium, different flow rate, different lift range, therefore, its structure of course is not the same, the material is different, in general, can be divided into:1, urban water supply 2, sewage system 3, civil and construction systems 4, agricultural water conservancy system 5, power station system6. Chemical system 7, petroleum industry system 8, mine metallurgy system 9, light industry system 10, ship system
- Q: Attention should be paid to the use of pumps?
- 7 water pump and pipe interface must be sealed, because if there is debris access, then the pump will cause damage to the interior. 8 for the water pump bearing is also the focus of inspection, use up to check whether the bearings wear,
