Abstract

The invention discloses a duplex metal cylinder body applicable to a hydraulic pump or a motor. The duplex metal cylinder body comprises a steel substrate, wherein a copper alloy layer is arranged on a plunger hole and an oil distribution disk surface of the steel substrate in a melting and casting mode; the copper alloy layer is composed of copper, tin, lead, nickel and zinc, wherein the lead content is controlled to be 10.5%. The duplex metal cylinder body enables a friction pair of the cylinder body to have the optimal lubricating property when the hydraulic pump or the motor works.

Description

A kind of bimetallic cylinder that applies to oil hydraulic pump or motor
Technical field
The present invention relates to a kind of bimetallic cylinder, particularly a kind of bimetallic cylinder that applies to oil hydraulic pump or motor.
Background technique
Cylinder body is the vital part of hydraulic pump/motor.In hydraulic pump/motor working procedure, cylinder body end face and oil distribution casing fit tightly, and plunger high speed to-and-fro motion in cylinder body plunger hole, completes suction/oil extraction work jointly simultaneously.In this process, the matching problem of above two friction pairs is most important.
The material that the cylinder body of most domestic hydraulic pump/motor adopts is at present single magnesium iron or bimetallic cylinder.Long-term test discovery, if solved the greasy property problem of friction pair, the performance of so whole friction pair will get a new look.But still relevant producer or R&D institution are studied causing the material of change friction lubricating performance at present.
Summary of the invention
The object of the invention is to, a kind of bimetallic cylinder that applies to oil hydraulic pump or motor is provided.The invention enables hydraulic pump/motor when work, the friction pair of cylinder body can have best greasy property.
Technological scheme of the present invention: a kind of bimetallic cylinder that applies to oil hydraulic pump or motor, is characterized in that: comprise steel base, founding copper alloy layer on the plunger hole of steel base and oil distribution casing face; Copper alloy layer is comprised of copper, tin, lead, nickel and zinc, and wherein lead content is controlled at 10.5%.
In aforesaid bimetallic cylinder, described tin content is controlled at 9%-11%.
In aforesaid bimetallic cylinder, described tin content is controlled at 10%.
In aforesaid bimetallic cylinder, described nickel content is controlled at 2%-4%.
In aforesaid bimetallic cylinder, described nickel content is controlled at 3%.
In aforesaid bimetallic cylinder, described zinc content is controlled at 2%-4%.
In aforesaid bimetallic cylinder, described zinc content is controlled at 3%.
In aforesaid bimetallic cylinder, described steel base is made by middle-carbon steel.
Compared with prior art, the present invention is by cylinder body is comprised of steel and Cuprum alloy, and controls the lead content (being controlled at 10.5%) in Cuprum alloy, and while making cylinder body work, the greasy property of friction pair is in Best Point, thereby reduces energy consumption, improves operational efficiency.The present invention also controls other constituent contents (tin, nickel and zinc), makes to use reliable and stable.The present invention also by middle-carbon steel as steel base, and in steel base founding copper alloy layer, make better effects if.
The present invention has passed through 1000 hours life tests of hydraulic pump product of 21MPa, can form batch production.
