In the plate and frame filter press dewatering effect is not HERSHEY′S, we should be how to solve? Here we explain.
The first step: to be the pressing pressure filter before operation: check cloth has no discount or overlap, the power supply is normal. Check can be carried out after pressing operation, first click on the "start" button, the pump starts to work, and then click the "pressing" button, the piston pushes the pressing plate clamping, clamping force arrived when setting high pressure hydraulic systems, automatic shutdown.
The second step: when filter feeding after pressing, can feed operation: open the feed pump, and slowly open the inlet valve, inlet pressure increased gradually to normal pressure. Then observe the leakage of liquid and filter plate of filter press, filter after a period of time to press the liquid outlet hole liquid gradually reduced, then explain the filter chamber filter residue is gradually filled with a liquid outlet, when no liquid or only a small amount of liquid that the filter chamber, filter residue is completely full cake formation. Such as the need to wash the filter cake or dried operation, can be subsequently, such as do not need washing or drying operation can be carried out for cake discharging operation.
The third step washing or drying: the filter cake is filled, shutting down the feed pump and the inlet valve. Open the washing pump or compressor, slowly open the inlet fluid or air valve, washing the filter cake or dried. After the completion of the operation, close the lotion pump or compressor and valve, cake discharging operation can be carried out.
The fourth step: first off the cake unloading feed pump and the inlet valve, inlet fluid or air intake device and a valve, and then hold down the operation panel on the "release" button, the piston rod drives the pressing plate back, back to the appropriate position, let go hold "release" button, manual block by block to pull the filter plate unloading cake, clean up the stick on the sealing surface of the filter residue, prevent the filter slag entrapment in the sealing surface of sealing performance, leakage phenomenon, thus a cycle of top.
