Abstract
The utility model discloses a motor belt regulator which is suitable for various oil pumping units in a production field for pumping oil for oil industry and motors in other production fields. The utility model leads a motor belt to keep the suitable rate of tension. The utility model comprises a tensioning mechanism and an adjusting mechanism, wherein the adjusting mechanism and the tensioning mechanism are connected to be arranged. Through the adjustment of the adjusting mechanism, the tensioning mechanism is abutted on the belt and a proper tensioning degree is obtained. The utility model has the advantages of compact structure, low cost, simple and safe adjustment and labor saving. Because the tensioning degree of the belt is proper, the service life of the belt is extended, and the accident that because a belt is broken, a well is stopped can be avoided. The efficiency for producing crude oil is improved, the material consumption is lowered, and workmen's intensity of work is lowered.
Description
Technical field
The utility model belongs to the supplementary equipment of motor, and particularly the motor belt tensioning device is applicable to the motor of all kinds of pumping units on the petroleum industry oil recovery well and the various motor of other production scene.
Background technique
In petroleum industry, pumping unit is the most frequently used oil recovery mode of production, accounts for 60% of the whole oil recovery mode of production.It is to rely on power to drive motor to carry out high-speed motion that pumping unit extracts underground crude oil, is connected by belt by motor and goes up speed reducer, and the high-speed motion of motor is converted into the low-speed motion of gearbox, and the oil well pump that drives the down-hole is produced continuously.Therefore, belt is must use material in the pumping unit production.Because belt is a rubber product, constantly bear tension force and frictional force aborning again, so belt belongs to the production easily-consumed products.From the on-the-spot applicable cases of recovering the oil, run into rain, snow weather the average life of belt about 1 first quarter moon, and belt frequently takes place especially owing to skidding problems such as causing fracture.If can not in time change, can cause the stopping production of pumping unit, bring harmful effect to crude oil production.According to field statistics, a bite well year consumes nearly 10 of belt.Therefore, the consumption of belt is undoubtedly a major issue of recovering the oil in producing.But the tight belt of motor jackscrew is used exactly to the main means of belt adjustment in the scene at present, makes belt remain higher rate of tension.Because belt is in the state of constant tension all the time, cause shorten the working life of belt, change frequent.Therefore, on-the-spot being starved of of recovering the oil a kind ofly can effectively be regulated the instrument of belt tension degree, to prolong the working life of belt, saves consumptive material, reduces cost.
Summary of the invention
The purpose of this utility model provides reliable, the quick and simple and direct motor belt tensioning device of a cover, overcome defective of the prior art, make the motor belt remain suitable rate of tension, reduce the consumption of belt, reduce production costs, alleviate on-the-spot worker's labor intensity.
Use the present technique solution can reach above-mentioned purpose: the motor belt tensioning device comprises tensioning mechanism and regulating mechanism, regulating mechanism and tensioning mechanism connection, and the adjusting by regulating mechanism makes tensioning mechanism lean belt, reaches suitable tensioning degree.
Compare with existing motor belt adjustment mode, this tools structure compactness, low cost of manufacture, easy to adjust, safety labor-saving.Because the tensioning degree of belt is moderate, in the working life of having improved belt, avoided the generation that stops the well accident that causes because of the belt fracture.Thereby improved the efficient of crude oil production, reduced materials consumption, also reduced working strength of workers, had economic benefit and social benefit.
