Q:What are the advantages and disadvantages of the pump control system and valve control system in the hydraulic system?
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: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:What is the pumping property of concrete?
Pumping capacity means that fresh concrete can be transported by concrete pump, and concrete construction can be carried out with high efficiency. 'pumping' is a qualitative statement
Q:Is vane pump good or gear pump good?
1) the reversible design of gear pumps can also usually reverse, but reverse after the suction port change, and the pump safety valve does not work; leaf pump is generally not allowed to reverse. 3) the single acting vane pump can be designed to change the eccentric distance by moving the stator at the constant speed, so as to achieve the purpose of variable direction.
Q:How to calculate the motor power of metering pump?
Two Hydraulic power, metering pump rated flow (L/H) X, maximum pressure (Barg) / 36000 = kw
Q:Fire pump and shower pump flow head selection, high resolution.
2, the volume is greater than 10000 is less than 25000, the minimum water consumption of indoor fire hydrant is 15L/s
Q:Excuse me, what is the water pump from the lotus root?
The utility model relates to a self coupling sewage pump, which is composed of a base, a self coupling frame, a guide rod, a guide rod, a support seat, etc., and the utility model does not need bolt connection
Q:The difference between submersible pumps and centrifugal pumpsWhat's the difference between the two? What is applicable and what?
Difference:The installation position is different: one can discharge water, one is on the ground.The work principle is different: the principle of submersible pump is similar to the electric fan, centrifugal pump through centrifugal force to make the water throw out. According to the principle of centrifugal force design,
Q:What are the main performance parameters of hydraulic pumps?
speedOperating speed is the actual rotation speed of a pump (or motor) at work.Rated speed is the maximum speed that can operate normally for a long time under rated pressure. If the pump exceeds the rated speed, the work will cause insufficient oil absorption, vibration and noise, the parts will suffer cavitation damage, life expectancy.Minimum steady speed is the minimum speed allowed for normal motor operation. At this speed, the motor does not appear crawling phenomenon.
Q:What is pump suction work?
In the ventilation process, pump suction is formed. The ventilation process is the whole process from opening to closing of the exhaust port. Pump Qigong refers to the cylinder gas on the piston in the forced exhaust stroke and suction stroke done by the work
