Abstract
The utility model relates to an oil pumping device, particularly a manual oil pumping device of a diesel oil pump. The utility model is characterized in that a double lip-shaped sealing ring which is formed by a smooth inner ring and two outer rings of a ring protruding rib is arranged between a saw-tooth ring of a piston and the inner surface of a manual pump body, and an enclasping ring is arranged on the double lip-shaped sealing ring; a manual pump seal gasket is arranged between the left end surface of the manual pump body and the handle end surface of the piston. Furthermore, a spiral spring is arranged in a piston joint, and one end of the spiral spring is supported on the left end surface of a lower seat. Consequently, the oil sealing performance in a manual pump is raised, and meanwhile, the requirements of the machining precision and the assembly precision to parts can be decreased.
Description
The utility model relates to a kind of pump oil device, especially refers to the manual oil pumping device of oil transmitting pump of diesel engine.
As everyone knows, before the diesel engine starting, need with hand pump the diesel oil in the fuel tank to be pumped in oil pump and the oil circuit earlier, simultaneously the gas in the oil circuit is discharged; At present, the sealing of sliding between the hand pump inner carrier and the pump housing is that strict quality of fit own guarantees, but still is prone to leakage of oil, gas leakage.
In view of this, the purpose of this utility model provides a kind of manual oil pumping device of oil transmitting pump of diesel engine, between piston and hand pump body seal ring is set, and tightly prevents leakage of oil, gas leakage.
The purpose of this utility model is achieved in that a kind of manual oil pumping device of oil transmitting pump of diesel engine comprises hand pump body, piston, following, piston joint, helical spring, it is characterized in that: between the saw-tooth ring of piston and hand pump body internal surface, be provided with the double-lipped seal ring that the outer ring of smooth inner ring and the prominent muscle of two rings forms, on the double-lipped seal ring, also be provided with a hold-fast ring; Pump packing on the other hand is set between the handle end face of hand pump body left side and piston, and helical spring places in the piston joint and the one end is supported in down the seat left side, and in addition, the piston joint left end connects the right-hand member of piston.
Above-mentioned double-lipped seal ring is an elastic rubber sealing ring.
Above-mentioned piston joint is fixedlyed connected with being connected to of piston or is made an integral body.
Owing to adopt such scheme: improved the oil seal in the hand pump, simultaneously, can reduce requirement to other part processing and assembly precision.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 the utility model exemplary embodiments sectional view.
Among the figure: 1. 3. times seats of hand pump body 11. hand pump sealing gasket 12.O RunddichtringO 2. pistons, 21. piston handle 22. saw-tooth rings, 23. jump rings, 4. piston joints, 5. helical springs, 6. double-lipped seal rings, 61. hold-fast rings
The external cylindrical surface of the inner cylindrical surface of hand pump body 1 and piston 2 is slidingly matched, piston joint 4 left ends are fixedly connected on piston 2 right-hand members (or making an integral body), and the outside thread of piston joint 4 is connected with following 3 internal thread, following seat 3 is fixed on hand pump body 1 right-hand member, and an O RunddichtringO 12 is set in the termination, helical spring 5 is arranged in the piston joint 4, and an end is supported in down on seat 3 left sides, this helical spring 5 is in closed state, not only be difficult for getting rusty but also reducing axial position, because common helical spring 5 is to be between hand pump body 1 and the piston handle 21 not only to be exposed to outer but also strengthen the axial position (not shown).
Double-lipped seal ring 6 is that oil resistant rubber or PTFE stuffing materials are made, its inner ring is smooth cylndrical surface, and the outer ring is the end face of the prominent muscle of two rings separately, contact the internal surface (saw-tooth ring 22 can strengthen the combination force with double-lipped seal ring 6 inner rings) of hand pump body 1 with the outer ring with saw-tooth ring 22 positions of its inner ring contact piston 2, again with hold-fast ring 61 bandings and supporting double-lipped seal ring 6 on piston 2, rely on the resiliently deformable of double-lipped seal ring 6, play the double-layer seal effect, prevent the hand pump body 1 of slide relative and the oil leakage between the piston 2.
Hand pump sealing gasket 11 is to be made by rubber material, be between piston handle 21 end faces of hand pump body 1 left side and piston 2, the other annular groove that is provided with in hand pump sealing gasket 11 left sides, and a jump ring 23 places above-mentioned annular groove and its internal diameter less than hand pump body 1 internal diameter, moves (being moved to the left) with limited piston 2 relative to hand pump body 1 and can not throw off.After pump oil finished, when piston joint 4 and following 3 screw threads screwed, this hand pump sealing gasket 11 plays sealing effect for the second time, and was more reliable to reach sealing.
The use operating process of present embodiment:
When rotary-piston handle 21, make piston joint 4 with following 3 scyewed joint disengagement and under helical spring 5 effects, piston 2 slides left, and oil enters in the hand pump body 1 (oiling valve of oil transfer pump is in unlatching, outlet valve is in and cuts out) by following 3 oily passage, promptly finishes oil-absorbing process.
Promote piston handle 21 when to the right, make piston 2 overcome the elastic force of helical spring 5, move right until piston joint 4 is contacted with following 3 threaded ends, oil in the hand pump body 1, deliver to dump pump and the gas in the oil circuit is discharged (oiling valve of oil transfer pump cuts out, and outlet valve is in opening state) through following 3 oily passage with certain pressure.Then screw piston handle 21, piston joint 4 is connected with following 3, hand pump sealing gasket 11 is compacted simultaneously.
