Causes of insufficient pressure in diaphragm filter press

In the production and operation of diaphragm filter press, the filtering work of the equipment is mainly completed by pressure. Sufficient pressure can better meet the operation of diaphragm filter press and ensure the operation efficiency of diaphragm filter press. Therefore, when using diaphragm filter press, it is necessary to ensure that the equipment has sufficient pressure to avoid affecting the production efficiency of diaphragm filter press due to insufficient pressure.

First, the seal is not tight. The filter plate and filter cloth together constitute the filter chamber of diaphragm filter press. The sealing of the filter chamber directly affects the pressure supply of diaphragm filter press. When oil overflows from the telescopic rod of diaphragm filter press, or in the oil circuit reversing valve, the closed steel ball cannot function normally, it may cause the filter chamber of diaphragm filter press to be poorly sealed, affecting the pressure supply of diaphragm filter press.

Second, the hydraulic oil is insufficient. When diaphragm filter press works in a long-term and high-intensity environment, the hydraulic oil will slowly decrease. When the hydraulic oil inside the diaphragm filter press is reduced to the designed low point, the diaphragm filter press oil pump cannot pump enough oil, nor can it be delivered to the diaphragm filter press oil pipe in time. The pressure generated by the hydraulic pressure is naturally insufficient, and the pressure of the filter plate of the diaphragm filter press will naturally decrease.

Finally, this is an inevitable problem in the operation of the diaphragm filter press. In the long-term operation of the diaphragm filter press, the hydraulic pressure retracts and retracts tens of thousands of times, and the friction between the piston seal and the wall in the middle is very frequent, and the diaphragm filter press seal is damaged too quickly. This will cause the oil entering the hydraulic chamber of the diaphragm filter press to flow out from another hydraulic chamber, resulting in no power for the piston, thereby reducing the pressure of the filter plate of the diaphragm filter press.

The above are the reasons for the insufficient pressure of the diaphragm filter press. Through analysis, it can be seen that hydraulic oil plays a very important role in the operation of the diaphragm filter press. Therefore, during the use of the diaphragm filter press, it is necessary to do a good job of maintaining the hydraulic oil, replace the hydraulic oil in time, ensure the normal pressure supply of the diaphragm filter press, and ensure the operation quality of the diaphragm filter press.
