The gear oil pump of the two-way oil return off-load of the two-way repairing of above-mentioned a kind of internal drainage type is characterized in that: said protecgulum is provided with two oil outlets.
The gear oil pump of the two-way oil return off-load of the two-way repairing of above-mentioned a kind of internal drainage type is characterized in that: also comprise the draining hole, said draining hole is communicated with filler opening and chamber, gullet.
The beneficial effect that the utlity model has: under the conditional situation of some working condition requirement system bulk, be fit to supporting use; Reduced the volume of system; And built-in two one-way valves that play two-way repairing effect on bonnet, outside draining change the logical inlet port of inner draining, have improved the efficient of pump.
Description of drawings
Fig. 1 is the top plan view of the utility model.
Fig. 2 is the side cutaway view of the utility model.
Embodiment
For making structure characteristic of the utility model and the effect of being reached there are further understanding and understanding, cooperate detailed explanation, explain as follows in order to preferred embodiment and accompanying drawing:
Referring to Fig. 1; The gear oil pump of the two-way oil return off-load of the two-way repairing of a kind of internal drainage type comprises the pump housing 100 and pump cover 200, and pump cover 200 is provided with filler opening 221 and oil outlet 211; Pump cover 200 comprises protecgulum 210 and bonnet 220; Protecgulum 210 and bonnet 220 are arranged at the front end and back end of the pump housing 100 respectively, and oil outlet 211 is arranged on the protecgulum 210, and filler opening 221 is arranged on the bonnet 220.
Be provided with chamber, gullet 110 in the pump housing 100; Be provided with driving gear 120 and bearing support in the chamber, gullet 110, driving gear 120 plays the function of carrying liquid, and filler opening 221 is communicated with the pump housing 100 interior chambeies, gullet 110 with oil outlet 211; When using; Liquid gets in the pump housing from filler opening 221, through the transmitting effect of driving gear 120, liquid is exported from oil outlet 211 then.Filler opening 221 is communicated with through two one-way valves 222 with the pump housing 100 interior chambeies, gullet 110; The both sides of filler opening 221 also are provided with two hydraulic push rods 223; The push rod of hydraulic push rod 223 connects the spool of one-way valve 222, and hydraulic push rod 223 can back down the spool of one-way valve 222.
Referring to Fig. 2; This product also comprises two draining holes 224; Draining hole 224 is communicated with filler opening 221 and chamber, gullet 110; Cause towards oil sealing when oil in the axis hole in chamber, gullet 110 and the oil sealing hole is full of, pressure is very big and generate heat when serious, liquid can be back to filler opening 221 from draining hole 224, and once more again through in the chamber, one-way valve 222 entering gullet 110.When this pump is used in the system of two-way cylinder; During one chamber oil-feed, one chamber oil return; The hydraulic push rod 223 of oil return direction can back down the spool of one-way valve 222, makes liquid better to get in the filler opening 221 through one-way valve 222, has improved the speed of backhaul; Eliminated inner back pressure, one-way valve 222 has played the function of oil suction and pressurize simultaneously.
This product is fit to supporting use under the conditional situation of some working condition requirement system bulk, reduced the volume of system, and on bonnet built-in two one-way valves that play two-way repairing effect, outside draining changes inner draining and leads to inlet port, has improved the efficient of pump.
In sum; Be merely the preferred embodiment of the utility model; Be not to be used for limiting the scope that the utility model is implemented; All equalizations of doing according to the described shape of the utility model claim scope, structure, characteristic and spirit change and modify, and all should be included in the claim scope of the utility model.
