High pressure piston hydraulic seals

Update:2019-01-08

Modern high-efficiency reciprocating seals, DSH Seals share with you that, to a large extent, due to the development of pistons and piston rod seals for hydraulic cylinders (to a lesser extent due to cylinders), it can be very high Keep the leak to a minimum under system pressure. Many of the patented constructions for pistons in the form of basic seals, namely U-rings and V-rings, as well as U-ring piston rod seals, have greatly improved sealing performance.

The compact seal construction replaces the seal assembly or can be used as a replacement for heavy duty applications. Many double-acting seal configurations can be used to replace the back-to-back piston seal missed opportunity. The small friction is characteristic of many patented pressure-loaded seals, which are often equipped with wear-reducing seal rings to extend seal life.

Industrial hydraulic sealing systems may operate from 100 bar (1500 lb/in2) to 140 bar (2000 lb/in2) or even higher pressures. Aircraft hydraulic seal systems may operate at 210 bar (3000 lb/in2) and even up to 350 bar (5000 lb/in2). In heavy-duty hydraulic machines (such as music machines), it is possible to use more independent pressures up to 700 bar (10000 lb/in2). The basic requirement of a hydraulic seal is that it must be a high pressure hydraulic seal. At the same time, it must not have excessive friction, although there is a favorable factor that the liquid to be sealed is usually a lubricant (ie hydraulic oil).
