Variable speed fluid coupling and hydraulic coupler transmission device occupy critical role in the variable speed energy saving application market of China's blower fan, pump class, because its application constantly enlarges, the production kind is on the increase with batch, and its development is particularly swift and violent in recent years.
Current; The high rotating speed of forming by motor, fluid coupling, blower fan or water pump, in, powerful unit; All adopt sliding bearing; Adopt the unit of sliding bearing need dispose top petrol tank, guarantee that the sliding bearing to the inertia operation provides lubricated under the burst power-off condition, stop operating up to unit.Otherwise just cause sliding bearing easily because of lacking the lubricated bearing shell that burns out in short-term.When unit normally moves; The oil pump station that carries on the coupler is through motor, fluid coupling, blower fan or water pump and the top petrol tank while fuel feeding of oil feed pump in unit; Make top petrol tank be in oil-filled state all the time, and be back to the fluid coupling oil pump station through the exhaust oil return apparatus of being located at top petrol tank top.The structure of the exhaust oil return apparatus of existing technology is: the top petrol tank oil outlet tube is connected with the return tube vertical fixing; And on oil outlet tube, be provided with a Rectifier plate through adpting flange; The structure of Rectifier plate is in the middle of a plectane, to be drilled with aperture; Said return tube upper end bending after-opening is used for exhaust, and the lower end is connected to the oil pump station that carries on the coupler through flange and pipeline.This exhaust oil return apparatus is generally adopted because of simple and practical; But there is following shortcoming: when unit operation, get into the oil in the top petrol tank, be directly injected on the vertical return tube inwall in opposite through Rectifier plate under pressure; Splashing of producing on the return tube inwall and mist of oil can be through return tube the elbow water clock to the ground of top petrol tank outside; Not only produce greasy dirt, befouling environment, and cause the lubricant oil waste.
The model utility content
The utility model is directed against the deficiency that the exhaust oil return apparatus that has top petrol tank now is easy to generate oil leaking pollution, and a kind of novel top petrol tank exhaust oil return apparatus is provided.It has avoided exhaust oil return apparatus oil leaking pollution in the original performance of assurance equipment.
The technological scheme that the utility model solves the problems of the technologies described above is following: a kind of top petrol tank exhaust oil return apparatus; Comprise the oil outlet tube that top petrol tank, return tube and an end are connected with said fuel tank top; The other end of said oil outlet tube is connected with said return tube, is provided with a Rectifier plate in said oil outlet tube inside, and its characteristics are; Said Rectifier plate is rounded; Side at said Rectifier plate is provided with the axial fuel inlet hole, is provided with the radially oil outlet that is connected with said oil inlet hole at opposite side, and the outside diameter of said Rectifier plate oil inlet hole one side is greater than the outside diameter of said oil outlet one side.
The beneficial effect of the utility model is: owing to adopted the AND DEWATERING FOR ORIFICE STRUCTURE of the utility model; The oil that make to get into orifice plate sprays to the tube wall of oil outlet tube through oil outlet radially, rather than directly sprays to the return tube tube wall, has avoided in return tube, producing the mist of oil that splashes; Also just avoided oil to overflow from relief opening; Thereby thoroughly solved the leakage of oil problem, not only avoided environmental pollution, also reduced the oil plant waste simultaneously.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, the top of said return tube is provided with blind plate, and on the tube wall of the top of said return tube, is provided with vent.The diameter of said vent is 4 to 6 millimeters.
Adopt the beneficial effect of above-mentioned further scheme to be; Through the blind plate sealing return tube mouth of pipe, and on the tube wall of the top of said return tube, establish vent, can satisfy at the tonifying Qi needs of top petrol tank during to the unit equipment fuel feeding; Freely open the state ratio with the mouth of pipe of existing technology, more can prevent the mist of oil effusion; And the diameter of vent better effects if between 4 to 6 millimeters.
Further, said Rectifier plate is installed in the inside of return tube through flange.
Adopt the beneficial effect of above-mentioned further scheme to be, utilize the more convenient orifice plate of flange installation and change.
