- Q: How can the submersible pump level meter be connected?
- Installation of submersible pumps dedicated liquid level float, connected to the submersible pump power line (some submersible pumps bought with), or received submersible pump control circuit, high starting, low stop.
- Q: What are the advantages and disadvantages of the pump control system and valve control system in the hydraulic system? How to choose in the project?
- Large pump control valve controlled energy consumption at least 30% reason is that there are serious throttling loss of a throttle valve control system of severe fever but simple structure and low cost which is why now valve control system still occupy the main market reasons.Pump control system with complicated structure especially when serious nonlinear control unsymmetrical cylinder control effect is not ideal, but the biggest advantage is energy-saving and low fever America professor Monika points out that using the pump control system of hydraulic excavator energy efficiency compared with the valve control system can be improved by over 46% but costs are high. But in control, the three pump invented by Professor Quan LONG of China is a good solution. LZ can find the invention patent or find his paper on sage. It seems that there are three or four SCI about this pump
- 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: What is the relationship between the minimum suction vacuum of a pump and the required cavitation?
- Suction is allowed to pump the vacuum from the distance from the inlet, which is part of the field installation.The manufacturer of cavitation allowance is closely related to the design and process of pump. Estimation formula: cavitation allowance =10.33 meters - allow suction of -0.5 meters (safety).
- Q: What kind of motor does the hydraulic pump need?
- Calculation of actual oil pump power:First count the flow: Q=dn L / minD displacement / revN RPM / minThen calculate the actual power: N=QP/ (60K) kwQ flow L / minP MPa MPaK total efficiency (usually 0.85)I do not know what the landlord said, 2.5L is the displacement or flow at the end, the concept must not be confused
- 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.
- Q: Working principle and structure of external gear pump
- When the meshing teeth on one side of the suction chamber are gradually separated, the volume of the suction chamber is increased, and the pressure is lowered, and the liquid in the suction pipe is sucked into the pump; the suction liquid is divided into two parts to be pushed into the discharge chamber by the gear in the alveolus. When the liquid enters the exhaust chamber, the liquid is squeezed and discharged from the exhaust chamber into the discharge pipe because the teeth of the two gears are continuously engaged. The driving gear and the driven gear keep rotating, and the pump can continuously inhale and discharge the liquid. The pump body is equipped with a safety valve, when the discharge pressure exceeds the required pressure, the delivery liquid can automatically open the safety valve, so that the high-pressure liquid returns to the suction pipe.
- Q: Why is the flow of the pump too small will occur cavitation phenomenon?
- Throttling regulation is to change the opening of the valve to change the flow of the pump, that is to say, to change the characteristic curve of the pipeline. The commonly used to regulate the flow of exports, because the entrance throttle makes reduce the inlet pressure caused by cavitation danger.
- Q: What is the difference between the ground pump and the pump in the commercial concrete?
- Move back and forth; pour concrete into a certain area. After the filling is finished, the whole pump truck can be moved to another position quickly
- Q: Do you have a suction pump higher than 9 meters?
- This screw self-priming pump suction process can be more than ten meters or more, my family is using this
