Abstract
The invention discloses a power steering pump and a pump body surface treatment process of the power steering pump. The pump body surface of the power steering pump adopts a zinc plating surface. The pump body surface treatment process of the power steering pump is characterized by comprising the following steps that: a, a pump body is finely processed; b, the pump body is cleaned at high pressure; c, a process oil passage is sealed and blocked through a steel ball; d, the pump body is subjected to deoiling treatment; e, the pump body is subjected to derusting treatment; f, the pump body is subjected to acid activation treatment; g, the pump body is soaked into electrolyte for electroplating zinc; h, glaring treatment is carried out; j, passivation treatment is carried out; and k, baking is carried out. The power steering pump and the pump body surface treatment process of the power steering pump have the advantages that on the principle of not changing the basic structure and the appearance installation dimension of the existing power steering pump, the improvement and the enhancement are carried out by aiming the defects and the weakness of the existing power steering pump, and the service life of the power steering pump is prolonged through optimizing the existing structure, the materials and the surface treatment process.
Description
Technical field
The present invention relates to a kind of power assistance pump for steering and power assistance pump for steering pump housing process of surface treatment.
Background technique
Automobile steering system is used hydraulic booster and is started from the 1950's, and its working principle is to draw power from motor, drives hydraulic-pressure pump and produces pressure; Act on the oil cylinder of automobile steering machine, assist the driver steering wheel rotation, at present; Almost 90% passenger car and 100% commercial car all adopt hydraulic booster system, and in recent years, the development of the truck of China rapidly; Along with motor manufacturers such as Weihe River bavin, heavy vapour, Xi Chai, Yuchai constantly introduce powerful motor kind, the tractive force and the carrying capacity of the truck of China continue to increase, and increase sharply to 400 Thomas's power from 200 Thomas's power several years ago; And horsepower also in continuous increase, yet big variation does not take place in the situation of power assistance pump for steering and structure, has the phenomenon of high load with small power; Especially truck is used in the mine, basis on the large-tonnage vehicle, often overload transportation; And often be in the limited conditions state that the original place heavy duty turns to, at present, the manufacturer of power assistance pump for steering just merely increases the pressure and the flow of pump; Come increase to the reply capacity; Make power assistance pump for steering often be in the limiting operationg condition of big pressure, significantly reduce working life, and the main problem that occurs is: the wearing and tearing of rotor and blade; The stator abrasion deformation; Join oily side plate serious wear; High temperature worsens oil; High temperature lost efficacy the oil sealing class.
Summary of the invention
The purpose of this invention is to provide a kind of power assistance pump for steering that can increase the service life greatly.
The present invention for realizing the technological scheme that above-mentioned purpose adopted is: a kind of power assistance pump for steering, galvanizing surface is adopted on said power assistance pump for steering pump housing surface.
Another object of the present invention provides a kind of power assistance pump for steering pump housing process of surface treatment.
The present invention for realizing the technological scheme that above-mentioned purpose adopted is: a kind of power assistance pump for steering pump housing process of surface treatment may further comprise the steps:
Step a carries out fine finishing to the pump housing;
Step b carries out the high-pressure wash pump housing;
Step c is with steel ball plugging technology oil duct;
Steps d is with the pump housing processing of deoiling;
Step e, through acid solution to the pump housing processing of derusting;
Step f carries out acid activation to the pump housing and handles;
Step g is washed the back with the pump housing and is invaded the electrolytic solution electrogalvanizing;
Step h carries out bright dipping to the pump housing and handles;
Step j carries out passivation to the pump housing;
Step k is dried the pump housing.
Power assistance pump for steering of the present invention and power assistance pump for steering pump housing process of surface treatment in the basic structure that does not change existing power assistance pump for steering and profile installation dimension in principle, improve and strengthen to the defective of present power assistance pump for steering existence and weakness; Through optimizing existing structure and material and process of surface treatment, realize the power assistance pump for steering prolongation in working life, produce high temperature during owing to oil pump work; The working hydraulic pressure oil viscosity is reduced, cause the oil film protective function of the mechanical friction part of the pump heart to descend the wearing and tearing aggravation; In addition, the too high rubber oil sea that also can make of oil temperature is aging, and existing power assistance pump for steering all is a lacquered surface; The radiating efficiency of paint is far below metal; And be that the metallic surface heat diffusion area reduces greatly after spraying paint, so the present invention changes painted surface into galvanizing surface, be intended to strengthen the radiating efficiency on pump housing surface; Guarantee the hydraulic oil oil quality, prolong the life-span of rubber oil sea class.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is the process flow diagram of power assistance pump for steering of the present invention and power assistance pump for steering pump housing process of surface treatment.
Embodiment
As shown in Figure 1; Power assistance pump for steering of the present invention; Change the painted surface of the pump housing into galvanizing surface; Strengthened the radiating efficiency on pump housing surface like this; Guarantee the quality of hydraulic oil oil product, prolong the life-span of rubber oil sea class, the technological process of power assistance pump for steering pump housing process of surface treatment of the present invention is: on the pump housing fine finishing-high-pressure wash pump housing-technology oil duct steel ball shutoff-pump housing extensions-intrusion organic solvent deoil-hot water injection-chemical deoiling and degreasing-washing-acid solution derusts-washes-acid activation-washing intrusion electrolytic solution electrogalvanizing-washing-bright dipping-washing-passivation-washing-oven dry; The present invention in the basic structure that does not change existing power assistance pump for steering and profile installation dimension in principle; The defective that exists to present power assistance pump for steering is improved with weakness and is strengthened, through optimizing existing structure and material and process of surface treatment, and the prolongation in realization power assistance pump for steering working life.
