Description
Consolidations rubber on hydraulic cylinders, cuffs, consolidations of the directing rod and the piston Due to growth of ecological requirements to modern equipment obliges the increasing attention to pay domestic producers of hydraulic cylinders to such indicators as tightness, efficiency, smoothness, noiselessness of the movement, and also to consider indicators of non-failure operation and durability. Subject fast wear needs to subject hydraulic cylinders with consolidations to the long and laborious work demanding operations with greasy details, and also special equipment.

The available literature, reference books on consolidations and catalogs of producers do not contain justifications of an optimality of the offered designs neither from a technical aspect, nor from economic. On working surfaces of rods and sleeves of a hydraulic cylinder it is difficult to provide and support the high frequency and lack of microdefects in the form of a time, sinks, risok, zaboin, traces of corrosion and demolitions of a chromic covering. The frictional stream of the molecules of working liquid which stuck to a rod of a hydraulic cylinder demands installation before consolidation of antisplash elements, the slowing-down wear of consolidations and hit of dirt in the working planes of a hydraulic cylinder.

The factors influencing the choice of type and the sizes of section of consolidations:

  • Admissible side plays in support of a rod and the piston
  • Limitation of locations of consolidation with a small difference in the diameters of the piston and a rod.
  • Degree of impurity and type of working liquid
  • Temperature range of operability of hydraulic cylinders
  • Working and maximum speeds of a rod
  • Hydraulic cylinder operating modes on the frequency of frequency of the courses.

It is more difficult to exclude hydrodynamic leaks in the form of drops from a fast-moving rod. For excavators peretechka on consolidation of the piston in volume to several cm ³ / mines are usually allowed that allows to use the most wearproof firm cutting consolidations like piston rings.

Characteristics of mobile consolidations of a hydraulic cylinder are defined by the materials applied in them. Traditionally — rubber which belongs to cheap and technological materials. If pressure more than 10 MPas rubber consolidations demand anti-extrusive protection by means of protective rings from more rigid materials that complicates and raises the price of a design. Polyurethane consolidations possess bigger wear resistance and anti-extrusive firmness, the lowered friction coefficient. The working resource of polyurethane consolidations is 3-4 times higher than rubber.

A number of semifixed plastic in comparison with the previous materials have the high module of elasticity, they are efficient with a pressure up to 40 MPas without additional protection. Working edges Haytrel allow to reach the highest tightness, however they are sensitive to microdefects of a surface of a rod, as a rule, they are supplied with podzhimny rings from rubber or steel.
