Repair of common sense

 

Gear pump repair knowledge with the use of time to improve, gear pump will show a lack of oil, or even not out of the oil and other problems, the first reason is the relevant parts wear too much. The first gear pump wear parts are automatic shaft and bushing, passive gear hole and shaft pin, pump shell cavity and gear, gear face and pump cover. When the primary technical target of the worn smooth oil pump fails to meet the requirements, it shall be disassembled and differentiated to find out the worn part and level and accept the response method to repair.

What should I pay attention to when buying solenoid valves? ZF HYDRAULIC remind you:

 

1. If it is bulk purchase of solenoid valve, must choose the regular solenoid valve manufacturers! (for example: ZF hydraulic)

 

2 buy solenoid valve must sign a formal contract with the manufacturer!

 

3. Before bulk purchase of solenoid valve, be sure to let the manufacturer make prenatal sample confirmation!

Reduce the noise

 

In order to reduce noise, it is necessary to carry out an actual survey of the noise source, measure and analyze the sound pressure level of the hydraulic system, and carry out frequency analysis, so as to grasp the size and frequency characteristics of the noise source. The corresponding measures are listed as follows:

Use low noise motor; Elastic coupling is used to reduce vibration and noise caused by the link.

(2) in the motor, hydraulic pump and hydraulic valve installation surface should be set up anti-vibration rubber pad;

Try to use hydraulic manifold instead of pipe, in order to reduce vibration;

(4) use accumulator and rubber hose to reduce the vibration caused by pressure pulsation,

The accumulator can absorb noise up to 10 Hz, while high frequency noise is very effective with hydraulic hoses. (5) with a sound insulation cover with sound absorption material, the hydraulic pump cover can also effectively reduce the noise;

6 system should be set up in the air relief device.

Hydraulic parts surface requirements and processing

As the main parts of oil cylinder, single pillar for mining, hydraulic support, gun tube and other products, the processing quality directly affects the life and reliability of the whole product. Cylinder processing requirements, its inner surface roughness requirements for Ra0.4 ~ 0.8µ M, strict requirements for coaxiality and wear resistance. The basic feature of cylinder is deep hole machining, which has been troubling the machining staff.

By rolling machining, the residual compressive stress left on the surface layer is helpful to close up the micro-cracks on the surface and hinder the expansion of erosion. Thus, the anti-corrosion ability of the surface can be improved, and the generation or expansion of fatigue crack can be delayed, thus the fatigue strength of the cylinder can be improved. Through rolling forming, a layer of cold work hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of grinding pair, thus improving the wear resistance of the inner wall of the cylinder and avoiding the burn caused by grinding. After rolling, the surface roughness value decreases, which can improve the matching property.

Hydraulic valve as the control hub of the hydraulic system, the movement is frequent, the components of the precision requirements, sealing, reliability requirements are very high, most of the foreign enterprises have adopted rolling to improve the precision with.
