In the use of screw jack convenient at the same time, its regular inspection and maintenance, it can not only extend the service life of the screw jack, but also make the use of more safe and reliable, to play the most effective inspection and maintenance role, can be carried out from the following:
1, the transmission part should have sufficient lubricating oil, wearing parts must be frequently inspected, repaired and replaced. The bolts of the machine, especially the parts that often vibrate, such as slewing bearings and lifting arms, should be checked for looseness. If there is loose, the bolts must be tightened or replaced.
2、After 1500 hours of work of the screw jack, the electromechanical system should be repaired.
3、After 5000 hours of work of the screw jack. Screw jack engineering, electromechanical system repair.
4、After 10,000 hours of work of the screw jack. Screw jack engineering, electromechanical system repair.
5, the brake of each body should be regularly inspected and adjusted, brake shoes and brake wheel clearance should be adjusted to ensure flexibility and reliability. In the friction surface, there should be no dirt, dirt must be cleaned with gasoline or thinner.
6, reducer, gearbox, external gear and other parts of the lubrication and hydraulic oil are in line with the requirements of the lubrication table.
7、Be careful to check whether there are broken and loose strands in each department. If it exceeds the relevant regulations, it must be updated immediately. The maintenance of steel wire rope should be carried out in strict accordance with the national standard.
8. often check the connection of each department, if there is loose, should be tightened. Bolts should be under tight pressure (check the method available to cause compression of the rotating arm), a small shaft all connections must have openings and need to be completely open.
9, often check the normal operation of the institutions, whether there is noise, if found fault, must be promptly eliminated.
10、When installing, dismantling and adjusting the rotary mechanism, care should be taken to ensure that the centerline of the reducer is parallel to the centerline of the gear, the meshing surface is not less than 70%, and the meshing gap should be appropriate.
11、Check all wires and cables regularly for damage. Wrap and replace damaged parts in time.
12、When the motor overheats, it should stop in time and continue to run after troubleshooting. Motor bearing lubrication should be good.
