Description
What the utility model oil transfer pump hand pump oil device related to is a kind of hand pump oil device that is applicable to oil transmitting pump of diesel engine or other oil transfer pumps.
Diesel engine is at prestart, if entrained air in the oil-feed oil circuit generally adopts hand pump oil device that the air in oil circuit and the oil pump is discharged.The sealing of common hand pump oil its piston of device and the matching gap of cylinder body and hand pump joint and fuel supply pump housing is not good, causes leakage of oil, gas leakage.
The purpose of this utility model is to provide a kind of oil transfer pump hand pump oil device at above-mentioned deficiency, in the cooperating of cylinder body and hand pump body, be provided with the lip seal circle, hand pump body lower device has following of hand pump, sets up seal ring between following of hand pump and the hand pump body, to reach the purpose that prevents leakage of oil, gas leakage.
Oil transfer pump hand pump oil device takes following scheme to realize: oil transfer pump hand pump oil device comprises cylinder body, the hand pump body, fixed cover, one-way valve, between cylinder body and hand pump body, be provided with the lip seal circle, at inferior part of the cylinder block back-up ring is housed, in the hand pump body, one-way valve is housed, helical spring, between cylinder body and hand pump body, be provided with spring, and on the hand pump body, fixed cover is housed, be used for supported spring and be used for the guiding that cylinder body moves up and down, hand pump body lower device has following of hand pump, between following of hand pump and hand pump body, be provided with seal ring, adopt between following of hand pump and the hand pump body to be threaded, hexagonal base circle diameter (BCD) that hand pump is following or body diameter and other polygonal base circle diameter (BCD) are bigger than the interior circular diameter of back-up ring.
Oil transfer pump hand pump oil device is owing to be provided with seal ring between cylinder body and hand pump, good sealing effect, it is combined again the hand pump bottom to be changed into the following two-part of hand pump body and hand pump, make the base circle diameter (BCD) of the following hexagonal of its hand pump or body diameter and other polygonal base circle diameter (BCD) bigger than the interior circular diameter of back-up ring, be convenient to adopt elastic sealing structure between the seated connection head and fuel supply pump housing under the hand pump, simultaneously between following of hand pump and hand pump body, be provided with seal ring, can prevent leakage of oil, gas leakage.Reasonable in design, the good sealing effect of oil transfer pump hand pump oil device, the oil suction of hand pump oil device, oil extraction efficient height, installation, easy to use is convenient to and oil transmitting pump of diesel engine or the supporting use of other oil transfer pumps.
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is an oil transfer pump hand pump oil device structural representation.
With reference to accompanying drawing, oil transfer pump hand pump oil device main structure has cylinder body 1, hand pump body 8, fixed cover 4, one-way valve 3, between cylinder body 1 and hand pump body 8, be provided with lip seal circle 5, lip seal circle 5 is for the centre has skeleton, inner ring is that full circle column sleeve, outer ring are the elastic caoutchouc of two prominent anchor rings separately, be pressed between hand pump body and the cylinder body by its elasticity, play seal action.Between cylinder body 1 bottom and hand pump body 8, adorn a back-up ring 6, rely on the boss of hand pump body 8 spacing.In hand pump body 8, adorn an one-way valve 3, helical spring 7 is equipped with in the one-way valve bottom, helical spring is supported on the interior step of following 10 of hand pump body.Between cylinder body 1 and hand pump body 8, be provided with spring 2, and fixed cover 4 is housed on hand pump body 8, be used for supported spring 2 and be used for the guide sleeve that cylinder body 1 moves up and down, hand pump body 8 lower devices have following 10 of hand pump, between following 10 of hand pump and hand pump body 8, be provided with O-ring seals 9 or other form seal rings, adopt between following 10 of hand pump and the hand pump body 8 to be threaded, hexagonal base circle diameter (BCD) that hand pump is following 10 or body diameter and other polygonal base circle diameter (BCD) are bigger than the interior circular diameter of back-up ring 6.
Owing in the hand pump body 8 of oil transfer pump hand pump oil device, one-way valve 3 is housed, when hand pump oil device in the raw the time hand pump stop 8 seat surface and the sealing surface of one-way valve 3 tightly sticks together, diesel oil in the oil transfer pump can not be entered in the cylinder body 1 of hand pump oil device, when compression cylinder 1, cylinder body 1 backs down one-way valve 3, thereby makes hand pump oil device finish the process of oil suction, oil extraction.
Claims (5)
1, a kind of oil transfer pump hand pump oil device, have cylinder body, hand pump body, fixed cover, one-way valve, between cylinder body and hand pump body, be provided with the lip seal circle, at inferior part of the cylinder block back-up ring is housed, one-way valve, helical spring are housed in the hand pump body, between cylinder body and hand pump body, are provided with spring, and on the hand pump body, fixed cover are housed, it is characterized in that hand pump body lower device has following of hand pump, is provided with seal ring between following of hand pump and hand pump body.
2, oil transfer pump hand pump according to claim 1 oil device is characterized in that the hexagonal base circle diameter (BCD) of following of hand pump or body diameter and other polygonal base circle diameter (BCD) are bigger than the interior circular diameter of back-up ring.
