Chamber Filter Press pump shaft and motor are not concentric and need to be adjusted as required

Jan. 10, 2020

Chamber Filter Press hydraulic oil temperature is too high: severe oil leakage caused excessive volume loss, repair the leaking place, and ensure sealing. The relative frictional force of the moving parts is too large, and the parts are processed and assembled according to the requirements of the assembly; oil leakage in the system: the seal is damaged or reversed, replace the seal or correct the installation. The pipe joint is loose and needs to be tightened. Check valve cone valve and valve seat are not strict, or the valve seat is damaged, repair or replace the valve seat. The gap between the moving parts' opposite surfaces is too large. Replace parts to reduce the fitting clearance. The pressure is adjusted too high, and the working pressure is appropriately reduced.

The hydraulic system of the box filter press generates vibration and noise: hydraulic pump: the pump shaft is not concentric with the motor and needs to be adjusted again according to requirements; the coupling is loose and should be tightened; the hydraulic pump parts are severely worn and need to be replaced; the oil quantity is insufficient and the oil is absorbed Insufficient sealing of the tube causes suction, or the oil filter is blocked and the oil absorption is not smooth. Add oil, handle the seal, and clean the oil filter.

Overflow valve: the gap between the valve core and the valve body is too large, or there are burrs or debris, replace the valve core, adjust the clearance, clear burrs and debris; the box filter spring or valve seat is damaged, replace the spring, repair Valve seat; damping hole is blocked, clean the damping hole. Reversing valve: The solenoid is not well sucked and needs to be repaired; the spool is stuck, cleaned or refurbished; the spring is damaged or too hard and needs to be replaced. The hydraulic cylinder seal of the box filter press is too tight or the processing and assembly errors cause too much motion resistance. Adjust the seal tightness appropriately, replace or repair the unqualified parts, and reassemble.

As a Chamber Filter Press Factory, I would like to share with you the problem of improper placement of the filter cloth of the filter will cause the filter room to be unable to seal.

The filter plate and filter cloth under pressure of the filter press must be under strong pressure to achieve a closed filter chamber structure. When this pressure is insufficient, the pressure applied to the filter plate is less than the pressure of the filter liquid, and the filter liquid is naturally filtered. Can take it for granted.

When the edge of the filter press is damaged, even if it is slightly raised, even if one side is often worn, it is also in contact with other filter plates. No matter what the pressure is, the formed filter room will penetrate. This point we judge according to the situation of the leakage point, the penetration caused by the damage of the filter plate is generally relatively large, and may even spray.

The filter cloth of the filter press is incorrectly placed. There are many reasons why the filter room cannot be sealed. We need to start by simply surrounding the filter room to see if the filter cloth is wrinkled or the edge of the filter cloth is defective. Because the structure of the filter room is formed by the filter plate and filter cloth being inserted into each other and subjected to strong pressure, the general filter plate is not prone to problems, and the rest is the filter cloth. It is necessary to form a seal between the hard filter plates, which plays a key role in the filter cloth. The wrinkles or incompleteness of the natural filter cloth easily cause gaps between the filter plates, and the natural filter room will not form a seal. Our company also has Automatic Pressure Filter Press on sale, welcome to consult.
