What causes the hydraulic system, the motor suddenly can't carry the hydraulic pump.
Use the anti-foam good oil solution, or add the antifoaming agent in the oil. The noise and control of hydraulic pump are made from the structure of hydraulic pump. (5) the vibration avoidance of the oil discharge line and mechanical system: (1) connect pumps and valves with hoses. (2) to prevent the resonance and standing waves from occurring when the pipes are configured. The support of the piping should be set up on the solid platform.
Adjust the overflow valve, check system pressure from small to large, to normal working pressure, overflow valve to adjust, 2, the system does not work, the system should be a pressure relief, if this period of time (light) also stop the pump and motor doesn't work, could valve jam, check, try again after cleaning there should be no problem. 3, the motor self-overload sets too low to cause tripping, stop pump, this may also have, some element quality is bad to cause. 4, the system other valve or the flow oil does not smooth the pressure overloading system overload stop pump 5, the wiring problem, in order to become overloaded These are the basic reasons, but one or two are likely to be large, and others are not to be excluded from the work

The hydraulic pump suction line is tightly sealed to prevent entering the air. (2) to design the tank properly, the return tubing should be made to the box wall at a 45-degree Angle and to be inserted into the oil in the wall of the box. The speed should not be too high to prevent the oil from being poured into the tank while the air is mixed in. The board should be set in the tank. Make the bubble float in the oil without going into the suction tube. (3) the fuel tank of the oil to add to the oil line is shown in the height of the suction pipe must be immersed in the tank, two-thirds of the depth of hydraulic pump oil absorption liquid to the distance as short as possible, in order to reduce oil absorption resistance. If the fluid viscosity is too high, low oil fluid should be replaced. The filter is blocked to remove the dirt in time. This effectively prevents excessive air immersion. (4) use the anti-foam good oil solution, or add the antifoaming agent in the oil.
Hydraulic pump suction empty refers primarily to the pumped into oil mixed with air, this phenomenon is not only easy to cause cavitation, adding noise, but also influence the volumetric efficiency of hydraulic pump, the working oil metamorphism, so it is not allowed phenomenon in the hydraulic system. Main reason: the fuel tank design and tubing arrangement is unreasonable, lack of the oil tank: suction tubing in oil tank is too shallow, hydraulic pump oil absorption position is too high, the oil viscosity is too big: hydraulic pump flow area of oil suction mouth is too small, make oil absorption confusing: oil filter surface is dirt blocking: pipeline leaks or return pipe not immersed and cause a lot of air into the oil in the tank.
