Mobile portable concrete batching plant Hydraulic System Maintenance

Daily maintenance can not only reduce the mobile portable concrete batching plant failure, increase the production efficiency, but also extend the service life. This requires the user to maintain the hydraulic cylinders. The avoidance of cavitation problems in hydraulic cylinders is an important maintenance item. Cavitation will cause the appearance to become black, and even the appearance of the support ring and the seal ring, and then constitute a hydraulic cylinder to cause internal leakage. When cavitation acts together with other types of corrosion, it will accelerate the corrosion rate of the hydraulic cylinder's primary parts several times, and then seriously affect the normal operation of the mobile concrete batching plant. How to maintain the hydraulic system of portable concrete batching plant?

1, Strictly choose the hydraulic oil
The use of good quality hydraulic oil can effectively prevent the hydraulic system from appearing bubbles during the working process. When selecting the hydraulic oil , it should be selected according to the lowest temperature in different areas, and the hydraulic oil should be filled according to the specification of the dipstick. The hydraulic system should also be kept clean. (When filling the hydraulic oil, the moisture and other impurities should be avoided), often check the oil level and oil color, assuming that the blisters, foam, or oil became milky are founded, you should carefully find the origin of the air in the oil, and promptly eliminate it. Reasonably planning the heat dissipation system of the mobile concrete batching plant and avoid excessive oil temperature are the key to maintaining the normal temperature of hydraulic oil. Assuming that the presentation is abnormal, you should find the elements and clean them in time. In the operation of the hydraulic operating lever and the distribution valve, we must strive for stability, not too fast, too fierce, it should not be repeated to increase the engine throttle to minimize the impact of hydraulic oil hydraulic components.
2. Maintain the normal clearance of each component
When manufacturing or repairing the main parts of hydraulic cylinders (such as cylinders, piston rods, etc.) in portable concrete batching plant, they should be assembled in accordance with the lower limits of the tolerances of assembly dimensions. Practice has proved that this can well reduce the occurrence of cavitation. If cavitation has already occurred in the hydraulic components, the pitting and surface area char of cavitation can only be removed by the metallographic sandpaper polishing technique, and the general sandpaper can not be used for grinding.
3. Pay attention to exhaust when servicing
After the hydraulic cylinders of mobile portable concrete batching plant are repaired, the hydraulic system should be allowed to run smoothly for a certain period of time, so that the hydraulic oil in the hydraulic system can be fully circulated; if necessary, the hydraulic cylinder inlet pipe (or return pipe) can be disassembled to make the hydraulic oil overflow. In order to achieve the effect of a single hydraulic cylinder exhaust.
