Description
Technical field
The utility model relates to the reciprocating receipts oil pump of a kind of mechanical type, and especially a kind of mixture by the sump oil in oilfield sump oil pond and mud exhausts voluntarily and loads the pump of fuel tank.
Background technique
Along with the time limit of oil field development increases, when particularly development late stage crude output declines, general employing edge pumping unit extracts crude oil, but the power consumption of edge pumping unit is very large, to the lower well site of output in order to reduce energy consumption, changing and adopting the operation of bailing mode to obtain crude oil, but in bailing process, keep away unavoidable by the periphery farmland of crude oil pollution to operation area, crops are polluted.In order to address this problem, the method that have employed oil storage of digging pit reduces the pollution to farmland, when crude oil stores up some, oil refinery transported to by fuel tank of just must being reloaded by ground crude oil in time, usually the crude oil loading of landing has been come as feeding liquid pump to fuel tank by latent oil ground pump, but adopt pump operated complexity oilyly of diving, and cost is higher.
Model utility content
It is simple, simple to operate that the utility model object is to provide a kind of structure, sump oil collecting pump ground crude oil being evacuated to from oil sump to fuel tank that cost is low.
Goal of the invention of the present utility model is achieved in that
A kind of greasy dirt collecting pump, comprises the pump housing, bushing, plunger, feed liquor assembly, discharge opeing assembly.The described pump housing is provided with cavity; Described cavity comprises the piston reciprocation chamber of interpenetrating, discharge opeing valve pocket, feed liquor valve pocket and active chamber; Described bushing be tubulose, coordinate with described piston reciprocation chamber fixing, and be sealed and matched fixing by letter body and the described pump housing; Described plunger bushingly to coordinate with described, moves reciprocatingly in described piston reciprocation chamber; And be connected with drive unit; Described feed liquor assembly is positioned at feed liquor valve pocket, and described feed liquor assembly comprises feed liquor one-way valve; Described feed liquor one-way valve connects liquid entering hole; Described discharge opeing assembly is positioned at discharge opeing valve pocket, and described discharge opeing assembly comprises discharge opeing one-way valve; Described discharge opeing one-way valve connected drainage mouth; The volume sum of described feed liquor valve pocket and feed pathway is less than the volume sum in described active chamber and piston reciprocation chamber.
Further, the diameter of described feed liquor valve pocket is less than the diameter of described active chamber.
Further, described plunger is hollow structure of mosaic.
The utility model has the following advantages:
1, the utility model is owing to eliminating edge pumping unit, greatly reduces energy consumption.
2, general reciprocating pump must have malleation to work, and self does not have suction capacity.And the utility model adopts the volume sum of feed liquor valve pocket and feed pathway to be less than the volume sum in described active chamber and piston reciprocation chamber, piston reciprocation is made to form self-priming.
3 and the utility model structure is simple, simple to operate, cost is low.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described further, following examples are only preference, scope of the present utility model is limited, on the contrary, its objective is and wish contain in the category being arranged in the scope of the claims of the utility model institute wish application of various change and tool equality.
Below in conjunction with figure, the utility model is described further:
A kind of greasy dirt collecting pump, comprises the pump housing 1, bushing 3, plunger 2, feed liquor one-way valve 4, discharge opeing one-way valve 5.
The pump housing 1 is provided with the piston reciprocation chamber 11 of interpenetrating, discharge opeing valve pocket 12, feed liquor valve pocket 13 and active chamber 14.
Bushing 3 of tubulose coordinates fixing with piston reciprocation chamber 11, and is sealed and matched fixing by letter body 6 and the pump housing 1.
Plunger 2 coordinates with bushing 3, and plunger 2 can relatively bushing 3 to move reciprocatingly, and plunger 2 moves reciprocatingly simultaneously in piston reciprocation chamber 11; And be connected with drive unit.
Feed liquor one-way valve 4 is positioned at feed liquor valve pocket 13, and feed liquor one-way valve 4 connects liquid entering hole (not marking in figure); Discharge opeing one-way valve 5 is positioned at discharge opeing valve pocket 12, discharge opeing one-way valve 12 connected drainage mouth (not marking in figure); The volume sum of feed liquor valve pocket 12 and feed pathway 45 is less than the volume sum in active chamber 14 and piston reciprocation chamber 11, thus creates suction, makes the crude oil in oil-stored hole enter active chamber 14 smoothly.
The diameter R1 of feed liquor valve pocket is less than the diameter R2 of active chamber.
During work, plunger 2 is outwards taken out, and the feed liquor spring 43 between feed liquor pressure cap 46 and feed liquor spool 42 is compressed, and feed liquor spool 42 is opened, and ground crude oil enters feed liquor valve pocket 13 from feed pathway 45, flows to active chamber 14 by the feed liquor spool 42 opened.Plunger 2 inwardly pushes away, feed liquor spool 42 is closed, discharge opeing spring 53 between discharge opeing pressure cap 54 and discharge opeing valve seat 51 is compressed, discharge opeing spool 52 is opened, ground crude oil is that discharge opeing spool 52 enters discharge opeing valve pocket 12 from active chamber 14 by opening, and is transferred to fuel tank by Drainage pipe by liquid port.
