Bosch axial piston device

Bosch is an axial piston hydraulic system is important. It relies on the piston in the cylinder reciprocating motion, so that the volume of the cavity seal work to achieve a change in the suction pressure oil.

Bosch axial piston device for a reciprocating motion in the cylinder, so it's great exercise, in the course of their work needs to withstand enormous friction, therefore, the plunger require high hardness, wear resistance and service life and high accuracy and so on. Through research, the use of quenching can meet the technical requirements of the plunger.

Hardened steel is heated to the critical temperature Ac3 (Asia eutectoid steel) or Ac1 (eutectoid steel) over temperature, holding time, so that all or part of austenitizing and then cooling rate greater than the critical cooling rate faster Ms cold to the following (or Ms near isothermal) were martensite (or bainite) transformation heat treatment process. Quenching process in modern machinery manufacturing industry has been widely used. Important mechanical parts, especially in the automotive, aircraft, rockets application of steel almost have been quenched.

structure type

Bosch is divided into axial piston axial piston pumps and radial piston pump in the form of two representative structures; piston-cylinder radial piston due belongs to a new type of high-tech and efficient pump, with the accelerating the localization of the radial piston pump piston pump applications is bound to become an important part; see the specific radial piston Encyclopedia; the following example only axial piston pumps explanation.

Bosch is the use of axial piston shaft parallel with the plunger bore, the volume change produced by the reciprocating motion in to work. Since the plunger, and the holes are circular parts, processing can be achieved with high accuracy, and therefore has a high volumetric efficiency, smooth operation, flow uniformity, low noise, the advantages of higher working pressure, but the hydraulic oil more sensitive to pollution, the structure is more complex, higher cost.
