Problems needing attention in maintenance of milling machine
When the milling machine breaks down, the relevant maintenance personnel should observe and pay attention to the following items when maintaining the machine:
1. When the milling machine system is working, it should be shut down first. When the pressure is not released or the control power is not cut off, it is forbidden to repair the milling machine to prevent personal injury.
2. The maintenance site must be kept clean, and the surface dirt should be removed before removing the components or loose pipe fittings. During the maintenance process, all exposed passageways should be sealed with clean covers in time to prevent pollutants from entering the milling machine system. Grinding, construction or welding operations are not allowed on the maintenance site.
3. Maintenance or replacement of components must be kept clean, no sand, dirt, welding slag, etc. can be rinsed before installation.
4. When replacing seals, sharp tools are not allowed, and the seal or working surface shall not be damaged.
5. When disassembling and decomposing hydraulic components, attention should be paid to the direction and sequence of parts during disassembly, and the parts should be properly stored, and should not be lost, and the finishing surface should not be damaged. When assembling components, all parts must be clear and clean.
6. When installing the milling machine components, the tightening force should be uniform and appropriate to prevent the valve body deformation, valve core sticking or joint leakage.
7. When replacing or replenishing the working oil, the oil must be injected into the oil tank through the high-precision oil filter truck. The grade of working fluid must meet the requirements. In order to ensure the normal operation of the hydraulic system, it is necessary to change the hydraulic oil regularly. The time limit for changing the oil should be different according to the type of oil, working environment and operating conditions. Generally speaking, in places with continuous operation, high temperature, high humidity and dust, it is necessary to shorten the oil change cycle.
8. After maintenance, the maintenance parts of milling machine need to be confirmed. After no error, adjust according to the content of the hydraulic system debugging procedures. And observe the maintenance parts, and confirm that they are normal before they can be put into operation
