Description

Pneumatically controlled shaft chain lubricator

technical field

The utility model relates to an air-controlled well drilling machine in the petroleum industry, in particular to a chain lubricator for the air-controlled well drilling machine. Life, avoid equipment failure due to lubrication problems. the

Background technique

In the production process of downhole operations, the drilling machine is the most commonly used equipment for the operation team at present. The performance of the drilling machine is directly related to whether the production is going on normally. Therefore, ensuring the normal operation of the equipment is a necessary condition to ensure the smooth progress of production. In the use of equipment, due to the special position of the double-row chain and sprocket of the drum gearbox of the hoisting machine, maintenance is difficult, and it has become a blind spot in equipment maintenance. As a result, the chain cannot be maintained in time. After a long period of dry grinding, the chain and the sprocket that lack lubrication are severely worn. What is more serious is that once this happens, the two sprockets will be out of alignment. As time goes by, the hoist drum gearbox will be damaged to varying degrees. If this happens, chain and sprocket replacement or even roller gearbox repair work will be required. And this work is very loaded down with trivial details. During maintenance, it is necessary to remove the drum guard, and the drum and the drum gearbox can only be carried out by hanging the drum and the drum gearbox with a crane. It takes one to two days to simply replace the sprockets and chains. And if the internal parts of the gearbox are damaged, it is necessary to disassemble the gearbox and replace the damaged parts, which requires external repair personnel to complete. The cost of external repairs ranges from a few thousand yuan to tens of thousands of yuan, and the construction period is at least three to four days. Due to the equipment damage caused by poor lubrication of the sprocket and chain, the maintenance time is long and the workload is heavy, which not only increases the labor intensity of the workers, but also wastes a lot of production costs, and at the same time affects the normal workover process. Delayed the normal production of oil wells. the

Contents of the invention

The purpose of this utility model is to make full use of the characteristics of the gas storage tank of the well drilling machine itself, to provide an air-controlled chain lubricator for the well drilling machine, so that it has a certain automatic lubrication function, and eliminates major defects in the lubrication of sprocket wheels and chains . Ensure the normal operation of the hoisting machine, prolong the service life of the sprockets and chains, and avoid equipment failures caused by lubrication problems. the

The technical scheme of the utility model is: the chain lubricator of the air-controlled well drilling machine includes a fuel tank, an air intake part and an oil injection part, the air intake part and the oil injection part are fixed on the top of the oil tank, and the oil outlet pipe of the oil injection part is placed in the fuel tank. By artificially controlling the air intake control valve of the air intake part to make it enter the gas, the oil in the oil tank is sprayed on the sprocket and chain of the well drilling machine. the

Compared with the prior art, the utility model has the following beneficial effects and obvious progress: the lubricator uses the gas pressure of the gas storage tank of the well drive machine to push the lubricating oil to be sprayed out from the lubricating oil nozzle, and the operator does not need to remove the variable speed The box cover is filled with lubricating oil, which completely eliminates the phenomenon of sprocket and chain dry grinding caused by inconvenient maintenance in the past, ensures the effective cooperation of sprocket and chain, greatly prolongs the service life of sprocket and chain, and avoids equipment Damage, greatly reducing the number of equipment maintenance. It ensures the timely lubrication of the sprocket and chain of the hoisting machine, prolongs the maintenance cycle of the hoisting machine to a large extent, ensures the smooth progress of production, reduces the cost of maintenance equipment, reduces production costs, and relieves workers labor intensity. The device is practical and convenient, simple to manufacture, and low in cost. The sprocket and chain are lubricated by the gas pressure of the gas storage tank of the well dredging machine, and waste engine oil is used, so there is no use cost, only processing cost. It can not only realize the reuse of waste engine oil, but also greatly prolong the service life of the sprocket and chain of the drilling machine, effectively ensuring the normal production. the
