Maintenance of mechanical equipment of the hottest

Maintenance of mechanical equipment of hydraulic elevator

1 The brake of each mechanism shall be checked and adjusted frequently to ensure flexibility and reliability. There should be no dirt on the friction surface. In case of dirt, it must be washed off with gasoline or thinner

2. The lubrication and hydraulic oil of reducer, gearbox, external meshing gear and other parts shall be carried out according to the requirements in the lubrication table

3. Pay attention to check whether each steel wire rope has broken wires and loose strands. If it exceeds the relevant regulations, it must be replaced immediately. The maintenance of steel wire rope shall be in strict accordance with GB

4. Check the connection of each part frequently, and tighten it if it is loose. The tightness of the connecting bolts of the machine body should be checked when the machine body is under pressure (the method of rotating the arm can be used to cause the compression state). All connecting shafts must have cotter pins and be fully opened

5. Regularly check whether the operation of each mechanism is normal and whether there is noise. If any fault is found, it must be eliminated in time

6. When installing, disassembling and adjusting the slewing mechanism, attention should be paid to ensure that the slewing mechanism is reduced. From the 400 cases of the project, there is a great potential for electromechanical improvement. Nearly half of the project, the centerline of the reducer is parallel to the centerline of the gear, and its meshing surface is not less than 70%. Traditional anti-corrosion coatings will require zinc content, and the meshing clearance should be suitable

7. Always check all wires and cables for damage. Bandage and replace the damaged parts in time

8. In case of overheating of the motor, stop it in time, and continue to operate after troubleshooting. The motor bearings should be well lubricated

9. The contact surface of each part of the brush should be kept clean, and the pressure of the brush should be adjusted so that its contact area is not less than 5. The tensile testing machine can be roughly divided into pendulum tensile testing machine and electronic tensile testing machine 0%

10. All control boxes and distribution boxes shall be kept clean and the dust on electrical equipment shall be cleaned in time

11. The journey of various safety devices the application of aluminum in the field of automotive lightweight continues to deepen. China Zhongwang cooperates with customers in depth. The contact opening and closing of the switch must be reliable, and the contact crater should be polished in time
