Maintenance and maintenance of workover rig

The workover rig is a relatively complex large-scale equipment. If failure occurs during use, it will certainly affect the progress of the construction. Therefore, it is very important to maintain the workover rig. The maintenance of the workover rig is mainly divided into the following sections:

1, the maintenance of the transmission part

Mainly check the wear of each part of the chain to roller, bearing, to ensure that the lubricant surface of the chain case. It is necessary to check whether the position of the dead end and the live end of the brake is accurate. If any change is made, it must be changed in time. Pay attention to the degree of wear between each bearing and transmission, and grease in time. For example, the lubrication oil surface of the transmission case, whether there is abnormal noise, the abrasion of the crown pulley bearing, the wear degree of the traveling hook bearing of the big hook pulley. It is worth noting that the height of the brake lever is adjusted. If it is improperly adjusted, there is a possibility that the brake lever cannot be stopped or the empty vehicle cannot be put down. The correct adjustment height is 3-5 mm. Finally, remember to check each part of the connecting bolt regularly for looseness.

2, the maintenance of the liquid part

If the hydraulic equipment of workover rigs fails, it will affect the normal operation of the entire equipment. Therefore, the maintenance of hydraulic equipment is very important for workover rigs.

It must be kept in mind that the pressure of the hydraulic system cannot be easily adjusted in the field because it has been adjusted before leaving the factory. Also, when replacing hydraulic oil, remember not to open the manhole cover. If the working environment is poor and the dust is heavy, clean and replace the filter element regularly. Also check the level of lubricating oil on the inside of the car. Hydraulic system pressure gauges are easier to ignore during maintenance, but this is an important source of data. Therefore, it is found that pressure gauges must be promptly replaced when they are damaged or fail. In addition, pay attention to the temperature of the hydraulic oil, the normal temperature is 35-65 degrees. Once it is found that the temperature exceeds the maximum specified temperature, it is necessary to stop and check, and the trouble can be continued only after the trouble is eliminated.

3, maintenance of gas system

Compared with the above two parts, the maintenance of the pneumatic system is relatively simple. Mainly check the drain valve and dryer to see if there is any air leakage and the working condition is good. Check whether the air pump belt tension is appropriate. Pay attention to check the rubber pipeline of the air system to see if there is any aging phenomenon or cracks, and repair it in time. Also pay attention to the air system sender, pipelines and joints to see if there is loose gas leakage. Finally remind everyone that if it is winter, you must remember to add a little alcohol to the anti-freezer.

Because the workover rig is a relatively complicated device, once it fails to repair it is very troublesome, so the usual maintenance work to be done in place, in addition to maintenance, whether the staff is operating according to regulations is also very important.
