The hydraulic system of the plate and frame filter press is mainly to provide pressure, when the oil chamber A oil pressure increases when the piston to the left movement, Filter Plate the pressure plate to make it sealed. When the oil chamber B oil increases when the piston to the right movement, filter press release. As a result of manufacturing precision, filter press hydraulic system failure less, as long as attention to routine maintenance on it. As a result of wear and tear, every year or so there will be oil leakage phenomenon, Filter Plate then we must repair the replacement O-ring.
Common pressure filter hydraulic failure and pressure can not hold and hydraulic cylinder propulsion is not appropriate. The main reason for this is to remove and check the valve, replace the O-ring, clean check the solenoid valve or replace the solenoid valve. The main reason is to remove the valve, Filter Plate replace the O-ring, clean the solenoid valve or replace the solenoid valve. Filter press the hydraulic cylinder to promote the inappropriate is obviously the air was sealed inside, then as long as the system can be pumping, and can be quickly resolved.
Filter press filter plate this situation may be the guide rod on the grease, Filter Plate too much stains, making the guide rod and the contact part of the friction is too large, the hydraulic cylinder fuel tank is not normal. Deal with similar problems, to promptly clean the guide rod, and coated with butter to ensure its lubrication, with particular attention to the point is strictly prohibited in the guide rod wiping the oil, Filter Plate because the thin oil easy to make the bottom is slippery, the staff operation overhaul Easy to fall, Filter Plate to pay more attention. The other is to check whether the oil circuit has squeezed or blocked areas, so that oil flow.
Van filter press the general thickness of the filter between 60 ~ 85mm, each filter plate are square, in the filter plate on both sides of the reduced about 40mm to the internal concave down, the general depression down to the depth of about 25mm, The point is also dissatisfied with a high about 8mm protrusion, Filter Plate can be round, you can make the bar. This is the role of the filter plate in the process of re-filtration of the filter cake produced a good contact, so as to support the role of cake.
Van filter press in the middle of the filter plate, also with a hole through the hole, which feed the pipe, generally in the diameter of 100mm. And in the recess below or around, with a drainage hole, Filter Plate connected with the drainage pipe, the filtered liquid discharged from the equipment. Both sides are the same. Between the filter plate and filter cloth, the general filter cloth for a set of two, Filter Plate through the middle of the filter plate through a small number of filter cloth cylinder connected, so that you can well include the filter plate.
Van filter press filter structure there are different, it has two kinds of filter plate structure: the general filter plate and the border of the filter plate. Border filter plate is used to insert the filter plate of the square half of the phase made. These two kinds of filter plate staggered into the frame filter press filter room.
