Description

Observation structure of reciprocating pump gear guard shield

Technical Field

The invention relates to the field of petroleum engineering equipment, in particular to an observation structure of a reciprocating pump gear shield.

Background

Two reciprocating pumps with very similar structures, namely a drilling pump and a fracturing pump, appear in the field of petroleum engineering equipment. The most similar point is that the belt transmission stage of the two-stage transmission of the belt transmission and gear transmission from the original main motor to the crankshaft is cancelled, and the small gears are directly arranged at the two ends outside the supporting bearing of the motor shaft to drive the big gear on the crankshaft. Because the big and small gears are arranged at two ends of the reciprocating pump, the original structure that the gears are lubricated by splashing lubricating oil in an oil pool in the inner cavity of the frame cannot be adopted, and the gears must have a sufficient lubricating structure for forced lubrication. The crankshaft bearing and the connecting rod bearing of the two reciprocating pumps are changed from original splash lubrication as the main part and forced lubrication as the auxiliary part into all forced lubrication; in order to prevent dust, rainwater and the like from polluting lubricating oil and polluting the surface of a gear, in order to protect personal safety and reliability, a large gear and a small gear pair must be of a large gear and small gear protection cover fully-closed protection structure made of steel plates, and after the large gear and the small gear are fully closed by the large gear and the small gear, three places which need to be observed at any time are arranged: the first step is that whether the rotary joint for lubricating the crankshaft bearing and the connecting rod bearing is damaged or not is performed, if the rotary joint is damaged, lubricating oil can not completely enter the inner cavity of the crankshaft to lubricate a main bearing and a connecting rod bearing of the crankshaft, and the crankshaft and the connecting rod are quickly damaged; 2, whether the rotation direction of the large gear pair and the small gear pair is correct or not is observed, and the drilling pump and the fracturing pump which are two reciprocating pumps are unidirectional compressed liquid and directional, so that if the rotation direction is reversed, the rack can be damaged; 3, whether the lubricating oil of the large gear pair and the small gear pair is not interrupted or not, if the lubricating oil is interrupted, the gear pair is damaged quickly; therefore, the three places need to be observed all the time, and abnormal conditions are handled timely. Originally, there is not design and observes the window of the rotary joint which lubricates crankshaft bearing and connecting rod bearing at all, cause the rotary joint to have a problem, the lubricating oil leaks outside the crankshaft hole in large amount, not merely lose the expensive lubricating oil, has polluted the environment, must clear up the lubricating oil that leaks outside the gear guard shield in large amount, the more serious consequence is not dealt with in time, the reciprocating pump continues to operate, will cause the connecting rod bearing to lack the lubricating oil, destroy crankshaft and connecting rod, cause the major accident of the reciprocating pump to take place, although originally design an observation window at the pinion terminal surface, observe the rotation direction of the big pinion and small gear and the lubricated situation of the big pinion, but now the pinion terminal surface has designed a very good disc pump structure, can't observe at this place; therefore, there is a need to solve the existing problems, and an observation structure for a gear shield of a reciprocating pump is designed to become a problem to be solved.

Disclosure of Invention

The invention aims to provide an observation structure of a gear shield of a reciprocating pump.

The technical scheme of the invention is as follows:

the observation structures are arranged on the left gear shield and the right gear shield, the specified identification direction of the right gear shield is different from the specified identification direction of the left gear shield, the positions of the lubrication windows of the observation gears on the left gear shield and the right gear shield are different, faults do not necessarily occur on two sides simultaneously, and the specific change of each position can be observed.

Lubricating oil sign is that the suggestion observes lubricating oil, plays the warning effect, and organic glass is convenient for observe, observes whether gear lubricating oil pipe is erupting the lubricating oil that has certain pressure.

The method comprises the following steps of observing whether the rotation direction of a crankshaft is correct or not, attaching a reference mark to the end part of the crankshaft, and observing whether the rotation direction of a part with the fixed relative position of the reference mark is consistent with the specified mark direction of the rotation direction of a gear shield or not; the second function is to observe whether the rotary joint leaks oil, if the oil leaks, the quantity of the lubricating oil of the crankshaft bearing and the connecting rod bearing is insufficient; the organic glass is convenient for observation.

Four observation windows on two gear shields observe 6 functions, and the operator can the on-the-spot observation, also can be through the remote observation of video, can also report to the police through control system at every observation window installation sensor, diagnoses which position breaks down and needs in time to handle, and the prevention accident enlarges, has improved monitoring personnel's promptness and security in the monitoring process.
