Description
Technical field
The invention belongs to mechanical equipment technical field, specifically relate to a kind of positive displacement distributor with de-compression functions.
Background technique
Positive displacement distributor, mainly refers to the positive displacement distributor for automobile mechanical lubrication, is a kind of to connect lubrication delivery side of pump, is fitted on multiple pipeline with the oil content exported by lubricant pump, then by each Pipeline transport to the equipment of automobile lubricant housings required for each.Positive displacement distributor not only can make this position obtain lubrication to ensure, outside running swimmingly, simultaneously also can avoid laying between this position and lubricant pump too complicated pipeline.
Existing positive displacement Lubricators generally comprises positive displacement distributor and decompressing mechanism (with reference to Fig. 1), and its working principle is:
The motor driving gear pump of positive displacement Lubricators exports grease, decompressing mechanism is entered into through decompressing mechanism filler opening 10, after umbrella shape in decompressing mechanism de-pressure rubber 8 seals up decompressing mechanism oil outlet 9, umbrella shape is drawn in, makes grease enter conveying grease lines 7 from decompressing mechanism.Grease in conveying grease lines is after the first filler opening 1 enters into positive displacement distributor body, after umbrella shape in positive displacement distributor body de-pressure rubber 2 seals up the first oil outlet 3, umbrella shape is drawn in, grease is made to enter into oil storage cavity 4, now store oil clot 5 descending, store oily spring 6 and compress until oil storage cavity 4 stores full oil.
Motor stalls, umbrella shape in decompressing mechanism takes off the effect of pressure rubber 8 by grease pressure in conveying grease lines, umbrella shape is opened and descending, grease in conveying grease lines flows out from decompressing mechanism oil outlet 9, pressure in conveying grease lines declines gradually, when the first filler opening 1 pressure drop to a certain extent time, the action of oily spring 6 is stored in positive displacement distributor, store oil clot 5 up, simultaneously umbrella shape de-pressure rubber 2 umbrella shape is opened and descending, expose the first oil outlet 3, grease is exported from the first oil outlet 3.
Existing positive displacement distributor Problems existing is: longer at the pipeline running into conveying grease, when grease viscosity is higher, because the mobility of grease in pipeline is poor, when after motor stalls, although decompressing mechanism oil outlet 9 pressure reduces to zero, the pressure that oil delivery pipe road is 7 li is still increasing progressively, at the first filler opening 1 place pressure still in increase, cause store oily spring 6 slowly be unwilling to action, the first oil outlet 3 is slowly fuel-displaced.
Summary of the invention
In order to overcome the deficiency that prior art exists, the invention provides a kind of can adaptation compared with long pipe runs, higher, the fuel-displaced positive displacement distributor rapidly with de-compression functions of grease viscosity.
A kind of positive displacement distributor with de-compression functions, comprise distributor body, conveying grease lines, the first filler opening and the first oil outlet, described positive displacement distributor also comprises plunger type decompressing mechanism, described plunger type decompressing mechanism comprises oil suction chamber and go out oil pocket, the de-hydraulic plunger, piston spring and the chock plug that are provided with the second filler opening in described oil suction chamber successively, are slidably matched with oil suction chamber; Described go out oil pocket one end be provided with the second oil outlet, the other end close; Described oil suction chamber and go out between oil pocket to be provided with connecting pipe; Described second oil outlet is communicated with the first filler opening, the second filler opening and conveying grease pipeline connection;
