The filter presses widely used in the metallurgical industry, which is a commonly used solid-liquid separation equipment. It uses a special filter medium to exert a certain pressure on the load to make the liquid dialysis out. It is mainly composed of a frame, a pressing mechanism, and a filter mechanism. The pressing mechanism, which occupies the core position, can be divided into three types: manual, mechanical, and hydraulic pressing. In the hydraulic pressing mechanism, the hydraulic cylinder is an important executive component, and needs to have excellent performance to ensure high-intensity cyclic operation.
The main pressure cylinder provided by Hengli can fully meet the requirements of the equipment. The tailor-made sealing design can ensure excellent sealing performance to meet the high-pressure working conditions of the cylinder. Considering the hydraulic cylinder will receive lateral force during the filter press process, a copper alloy with excellent wear resistance is used as the plunger guide, which can withstand the lateral force, make the hydraulic cylinder more durable and reduce the cost of operation and maintenance for a filter press.
