Abstract
The present invention discloses method of avoiding oil leak of beam pumping unit speed reducer box, it is characterized in that the bearing in beam pumping unit speed reducer box and gear driving part are separated by sealing partition, the lubrication of gear driving part still adopts lubricating oil, while the lubrication of bearing is changed from lubricating oil to lubricating grease, the lubricating grease uses lithium-base lubricating grease. The leakless rate of the present invention can be 100%.
Description
The present invention relates to solve the method for gearbox leakage of oil problem, belong to a kind of method of avoiding oil leak of pumping unit speed reduction box that is used on the oil field.
At present, each oil field ubiquity the oil leak of pumping unit speed reduction box phenomenon, and the speed reducer leakage of oil has brought very big difficulty to the oil field management, influence normalization, befouling environment.After spilling, lubricant oil covers in the machine oil watch window, and can't the checking machine oil mass whether enough, if check untimelyly, certainly will cause scarce machine oil, cause that burn bearing, retarder beat accident such as tooth and take place, cause economic loss.In recent years, tried out the method for many solution speed reduceres leakage of oil on the oil field, as using metal o-ring, used still to occur oil leakage phenomenon after several days, reason is the wearing and tearing of having quickened in operation process spindle nose; Another kind method is to put additive in machine oil, strengthens engine oil viscosity, can only play a little effects to the casing junction, to serious not the working of axial plane seepage.Up to the present, yet there are no a kind of method of desirable solution oil leak of pumping unit speed reduction box.
Purpose of the present invention is exactly to provide a kind of method of avoiding oil leak of pumping unit speed reduction box in order to overcome above-mentioned the deficiencies in the prior art.
Purpose of the present invention can be achieved through the following technical solutions: this kind avoided the method for oil leak of pumping unit speed reduction box, be characterized in: bearing in the oil pumping unit reduction gearbox and gear transmission part are separated with seal diaphragm, oil lubrication is still adopted in gear transmission, and bearing changes grease lubrication into from oil lubrication; Lubricating grease adopts lithium grease; The antifriction-bearing grease loading can calculate with following formula:
G＝d
2.5/k(g)
G in the formula: lubricating grease loading (g);
D: bearing bore diameter (mm);
K: bearing module, ball bearing k=900, roller bearing k=350.
The present invention compared with prior art can have following advantage: owing to adopt seal diaphragm that gear lubrication and bearing lubrication are separated, like this, machine oil can not be splashed to the spindle nose place, the spindle nose place just engine oil leakage can not occur, and grease lubrication is adopted in bearing lubrication, lubricating grease again can seepage, so just fundamentally avoided oil leak of pumping unit speed reduction box.Adopt the method to reequip more than 100 oil pumping unit reduction gearbox altogether, leak rate is not 100%.
