Solve the problem of insufficient pressure of the vertical filter press
The reason for the insufficient pressure of the vertical filter press is that the hydraulic pump motor of the vertical vertical filter press is out of phase, the regulator is not in place, or the adjustment fails. Because of these three reasons, everyone can take corresponding measures to solve them, please study together.
First check whether the motor of the vertical vertical filter press is in good condition and not overheated. If the motor is damaged, check the wiring and components of the motor terminals, cables, thermal relays, contactors, etc. one by one along the motor load circuit until the cause of the fault is found. The fault is to eliminate and repair the damage. engine. If no motor problems are found, please consider whether the regulator is in good condition.
The reason for this failure is due to the failure of the pressure regulating valve: 1. The rated pressure of the pressure regulating valve is improperly adjusted; 2. The adjusting bolt is tightened too tightly or the vent is blocked by foreign matter or the product is improperly selected; 3. The seal is damaged and sealed. Strict, or there is foreign matter in the valve port and valve.
Solve the insufficient pressure caused by the failure of the pressure regulating valve: 1. Adjust the adjusting bolt of the pressure adjusting valve (tighten the bolt down to increase the working pressure); 2. Check whether the bolt adjustment is too tight and dredge the valve body. Oil drain hole; 3. Replace the seal ring of the drain valve or remove and replace the inlet valve and outlet valve disc.
How to solve the problem that the oil pressure of the vertical vertical filter press is too low or no pressure
Low pressure or no pressure is a problem often encountered in the working process of vertical vertical filter press. In order to avoid affecting the efficiency of the vertical vertical filter press, some solutions should be known in advance. The pressure drop of the vertical vertical filter press is described below. Or some stress-free solution
1. The pressure of the pressure reducing valve is low, loosen the locking nut of the pressure reducing valve, and turn the handle of the relief valve (turn inward to increase the oil pressure, and turn outward to decrease the oil pressure) to adjust the oil pressure, and adjust the normal pressure gauge model to work at rated Under pressure, the model of the electric contact pressure gauge is adjusted to be slightly higher than the rated working pressure.
2. After years of vertical vertical filter press (3 years-5 years or more), the sealing ring installed on the cylinder piston is worn out, and there is still a phenomenon that the pressure does not rise.
3. If the oil filter leaks, the pressure will not rise.
4. There is no oil in the fuel filter tank. Considering transportation and other issues, when a new machine leaves the factory, the hydraulic oil in the oil tank should be drained. If there is no oil, how can there be pressure?
5, the hydraulic oil is not filled enough, causing the suction to fail to be oiled, the hydraulic oil should be added at the position indicated by the liquid level gauge.
6. Lower the upper limit of the electric contact pressure gauge, adjust it to a proper position, and adjust the valve to reach the proper pressure.
In the future, when the pressure of the vertical vertical filter press is too low or there is no pressure, you can start from the above methods to find a suitable solution.
