The existence of leakage to the hydraulic system and mechanical work is harmful!

The existence of leakage is harmful to the work of the hydraulic system and machinery. For example, the pressure regulation of the hydraulic system is not high, the working ability is reduced, the actuator's motion speed is unstable, the working efficiency of the hydraulic system is reduced, and the oil temperature rises high, resulting in the waste of oil and other materials, which may lead to the failure of the hydraulic system and even the whole mechanical control. It can also pollute the environment and even cause fires.

Thus it can be seen that the leakage of hydraulic system not only affects the safety of the system, increases the machine's downtime, reduces productivity, but also increases the production cost and damages the products.

Therefore, the leakage of the hydraulic system must be controlled. Before controlling a leak in a hydraulic system, understand the cause of the leak.

The main causes of hydraulic system leakage are as follows: the design of hydraulic system has defects; Hydraulic system processing and manufacturing problems; There are errors in the assembling mode of hydraulic system; Lack of maintenance in the use of hydraulic system equipment.

The main factors

(1) Design factors

Design factors include selection of hydraulic components, hydraulic accessories, sealing components, pipe joints and hydraulic oils; Hydraulic system schematic diagram, anti-vibration, anti-impact link, eliminate side load on piston rod and drive shaft seals, system heat dissipation and oil pollution control design.

(2) Processing, manufacturing, storage and transportation factors

The processing, manufacturing, storage and transportation factors include the processing of the valve block throttle, the processing of the valve block jack, the processing of the sealing parts of the groove, groove, surface processing size and precision, roughness, static surface roughness and other aspects of the processing quality, sealing ring, hydraulic oil storage and transportation, and so on.

The seal ring is a self-tightening extrusion seal. Its basic working principle is that the seal elastic deformation, in the sealing contact surface to produce contact pressure. If the contact pressure is greater than the internal pressure of the sealing medium, leakage will not occur, otherwise leakage will occur.

(3) Assembly and debugging factors

Assembly and debugging factors include the selection of assembly screws, the loading of screw tightening moments, assembly methods, bolt anti-loosening measures, valve block inspection before assembly and cleaning of contaminants, pipe installation and sealing of static joint surfaces, etc.

(4) Later maintenance factors

Later maintenance factors include regular inspection of the pollutant content and oil temperature of hydraulic oil, replacement of seals, control of dust and moisture in the air into the hydraulic system and so on.

Through the mechanical and electrical hydraulic system manufacturers xiaobian sharing, in the understanding of the above points, in case of hydraulic leakage, there will be no fuss!
