Intelligent centralized dry oil lubrication system suitable for drilling machine crown block

Abstract

The invention discloses an intelligent centralized dry oil lubrication system suitable for a drilling machine crown block. The system involves a PLC, a plunger pump, an oil feeder, sensors, a displayer and the like, the PLC controls the plunger pump to convey oil in an oil tank to the oil feeder through oil pipes, and the oil feeder evenly conveys the oil to bearings on the drilling machine crownblock through the oil pipes. According to to the system, the sensors are arranged in the oil pipes to detect the pressure and the oil amount of the oil pipes, once a problem occurs, the problem is immediately fed back to the PLC and displayed on the displayer in real time, and the PLC is connected with the displayer through a network cable, so that remote monitoring on the high-altitude drilling machine crane bearing oil feeder and intelligent oiling / greasing are achieved on the ground.

Description

technical field [0001] The invention proposes an intelligent centralized dry oil lubricating system suitable for an oil drilling rig crane, which belongs to the field of automatic mechanical control of oil drilling rigs. Background technique [0002] There are currently thousands of land drilling rigs and offshore drilling platforms in the oil fields of China's petrochemical industry. Among these drilling equipment, the key equipment that needs to be lubricated are crown block, drawworks, traveling block and top drive. And the lubricating grease of these equipment all needs to add manually manually. Especially the crane, 40-60 meters high. Weekly or monthly lubrication requires the staff to climb up with tens of kilograms of lubricating grease on their backs, and then climb down after completing the work. The workload is extremely heavy and there are certain safety issues. Manual refueling has the following disadvantages: [0003] 1. Manual lubrication (manual oil gun lu...

AI Technical Summary

Problems solved by technology

[0003] 1. Manual lubrication (manual oil gun lubrication), high labor intensity and low efficiency;

[0004] 2. Manual lubrication, the control of the amount of lubrication can not meet the equipment lubrication design requirements;

[0005] 3. Manual lubrication has a large error in time, so that the lubrication points that should be lubricated by the time cannot be lubricated in time;

[0006] 4. The disadvantage of manual lubrication is that the amount of oil added is not enough, or it is overfilled: the former is insufficiently lubricated; the latter is usually filled too much, and the excess grease splashes into the ground or the sea, causing serious pollution;

[0007] 5. Manual lubrication increases the safety hazards of construction personnel, the position of the lubrication point is high, the load is heavy, and injury accidents are prone to occur;

[0008] 6. Manual filling causes waste of production cost and waste of grease;

[0009] 7. Manual lubrication will cause potential safety hazards if the equipment is running, but it needs to be stopped for the safety of personnel, which reduces the drilling efficiency

[0010] In addition to the above-mentioned problems of artificial greasing, the current drilling rig equipment is also pursuing unattended
