- 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: The suction pump has a nominal suction range of 30 metersHow deep can a well be sucked?Well, sixteen meters,
- That is impossible. The suction height of the pump is caused by the centrifugal force of the vacuum. The water is sucked into the vacuum
- 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: There are 6 pumps, two indoor fire hydrant pumps, two spray pumps, two outdoor pumps, three units, one master and one spare control cabinet. From the control room to the control cabinet, is there only 3 lines or 9 lines?... How do I get it? Where does the hydrant line come from?
- You said the three line refers to the control room, the control cabinet, the main pump directly start the straight line of water pump. Each pump should be equipped with single straight line Kai, reported that the cabinet Jinglian dynamic multi line linkage control board has three buttons corresponding to a remote spray pump, fire hydrant pump, pump start outdoor fire hydrant. This requires three straight lines, from the cabinet to the three pump control cabinet, which is the 9 line you call. The water pump control cabinet is provided with a terminal for supplying a remote pump. By looking at the wiring diagram of the water pump control box, you can find the technical personnel of the control cabinet manufacturer if you can't find them.
- Q: What's the pump? Where can I use it?
- Working principleIt transfers mechanical energy or other external energy of the prime mover to the liquid, increasing the energy of the liquid. Before the pump starts, the pump shell is filled with the liquid to be transported; after starting, the impeller is driven by the shaft to rotate at high speed, and the liquid between the blades must also rotate. Under the influence of centrifugal force, the liquid is thrown from the center of the impeller to the outer edge and obtains energy, and leaves the outer edge of the impeller at high speed to enter the volute pump shell. In the spiral case, the liquid slows down due to the gradual enlargement of the flow passage, and the part of kinetic energy is converted to static pressure, and finally flows into the exhaust pipe at higher pressure and is sent to the required place. When the liquid flows from the center of the impeller to the outer edge, a vacuum is formed at the center of the impeller. As the pressure at the upper level of the tank is greater than the pressure at the pump inlet, the liquid is continuously pressed into the impeller. Visible, as long as the impeller continues to rotate, the liquid will continue to be inhaled and discharged.
- Q: What is cavitation, centrifugal pump cavitation phenomenon how to solve?
- In order to make the pump full of liquid, usually in the valve installed at the bottom of the filter screen along the suction pipe, the valve until the end against the valve, strainer prevents the solid material into the normal operation of the pump impeller damage or hinder the pump.
- Q: Water pump outlet valve sequence
- In order to prevent the generation of water hammer when the pump stops the damage to the rubber head, should be immediately set rubber head pump outlet, the gate valve and the check valve is not a very convincing reason to decide the order of habits in our hospital order rubber head, check valve, gate valve1. Check valve located in front of the pump, I do not know what the significance is too great to think of.2. The actual installation sequence shall be: soft fittings, check valves, gate valves. The pressure gauge is best installed on the water outlet of the pump, but it must be in front of the check valve.Reason: 1) the soft joint is used to reduce vibration. The connection between the pump and the piping system, of course.2) normal work, the gate valve is not operating, and the check valve is frequent action, so the probability of maintenance is larger, when the maintenance of the pump closed, the water outlet valve can be maintained without affecting the normal operation of the system.3) the pressure gauge is installed in the check valve, which can prevent the impact and damage of water hammer on the pressure gauge.
- Q: What is the "variable" of a variable pump? Is the displacement change or the flow change? Thank you
- These two don't mean the same thing? That is, the pump outlet can be changed
- Q: How to distinguish the flow and displacement in the hydraulic pump? What's the difference between the two?
- If you're allowed to spend a minute, you can do it 20 times a minute, and that is, the amount of water you sprinkle at a time (1000) is *20.1000 (ML) *20=20000 ml =20 liters, this is the flow,Here is a formula for you to see,Pump displacement * pump speed = flow,
- Q: Please give me professionals to calculate, the cylinder bore is 100 and the rate of 20m/s, the leakage can be ignored, but to the large flow pump!
- 2. displacement and flowDisplacement refers to the pump (or motor) every turn a week, by the size of the sealing chamber geometry variable discharge (or enter) the volume of liquid, commonly used unit is ml/r (ml / rev). Displacement can be changed as a variable pump (or variable motor), and the displacement can not be changed into a quantitative pump (or a quantitative motor).Actual flow is the amount of flow at the outlet (or inlet) when the pump (or motor) is operating. As the pump itself leaks, the actual flow is less than the theoretical flow. As the motor itself has an internal leakage, to achieve the specified speed, in order to compensate the leakage, the actual flow of input must be greater than the theoretical flow.
