Description
Technical field
The utility model relates to a kind of oil return aspirator, belongs to the function basic components in the lubrication technical field.
Background technique
In the thin oil enclosed centralized lubrication circulatory system, the thin oil of each lubricating point of injection device, finish lubricated after, all need oil return to return lubrication station, again through purifying after by the lubricant pump suction, refill the equipment lubrication position by distributor.The equipment oil return generally all accumulates in the oil sump of body foot, the pasta position is lower, and the return opening of lubrication station is arranged on fuel tank panel top usually, for with the fuel tank of oil return drainage to lubrication station, need lubrication station is placed melt pit, it is poor that the return opening that makes it the return opening of lubrication station and equipment oil sump forms certain altitude, and oil return relies on flow by gravity to return the fuel tank of lubrication station.But this design proposal can increase a large amount of civilwork engineering quantities, especially for large-scale lubrication station, maintaining is very inconvenience also, so in many occasions, adopt service pump that oil return in the equipment oil sump is pumped to the high-order return opening of lubrication station, to finish the circulation oil return, can effectively simplify the ground civil engineering, and regular maintenance is also convenient, and in the known technology of this allocation plan, the service pump that adopts is selected hydraulic gear pump or rotor pump and so on volumetric oil pump usually for use, by its usage requirement, generally can not be inferior to 100 μ to the oil suction precision, thus must install the oil suction oil purifier additional, otherwise can aggravate the wearing and tearing of oil pump and cause oil pump to damage in early days.Because the dustiness of lubrication system oil return is higher; contain many metallic dusts and nonmetal dirt (comprising dust, fiber etc.); so the filter core of oil suction oil purifier can very fast obstruction during the drawback of this kind configuration mode was to use, and must often shut down and unpick and wash, maintenance workload is very big.Simultaneously, start and the shutdown to auxiliary oil pump is difficult to control automatically.In case auxiliary oil pump is in the oil suction disconnection state, then can cause oil pump to damage.Return the lubrication station fuel tank if the equipment oil return can not in time circulate, can cause the lubricant pump oil starvation and influence lubrication system and normally move.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of oil return aspirator, to overcome the above-mentioned defective that prior art exists.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of oil return aspirator, comprise motor centrifugal oil pump group, the regulating valve that is communicated with the outlet of motor centrifugal oil pump group and the oil return casing that is provided with cover plate, be provided with first deflection plate in the described oil return casing, second deflection plate and vertically be installed in first deflection plate and the oil return cabinet wall between the magnetic filter at runner place, one side lower part of oil return casing is provided with first valve that is communicated with equipment oil sump return opening, and the opposite side bottom is provided with second valve that is communicated with motor centrifugal pump group suction port.
The beneficial effects of the utility model, adopt technique scheme, can effectively solve pollution and the blockage problem of oil purifier, prolong the operating life of the auxiliary oil pump that is used for the oil return suction, reduce maintaining man-hour, can control simultaneously the operation of oil return suction automatically, and obviously improve the lubrication system reliability of operation.
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
