Abstract
The utility model relates to a reciprocating type water injection pump oil check head, which overcomes the defects that the existing reciprocating type water injection pump oil check head has poor sealing effect of a crankshaft to cause the oil leakage, shorten the service life of the water injection pump and reduce the efficiency of the pump. The reciprocating type water injection pump oil check head, comprises a crankshaft (4), an oil check head body (1), a framework oil seal (2) and a pressing cap (5), wherein the oil check head body (1) is fixedly arranged on the box body; and the framework oil seal (2), a gasket (3), the framework oil seal (2) and the pressing cap (5) are sequentially arranged from inside to outside on the inner hole of the oil check head body (1) and the excircle of the shaft head of the crankshaft (4). The utility model has the beneficial effects that the structure is reasonable, the reliability and service life of the oil seal structure can be improved, and the non-fault operating time of the pump set can be prolonged.
Description
Affiliated technical field
The utility model relates to the reciprocating type water injection pump of a kind of petroleum production, especially relates to a kind of reciprocating type water injection pump and keeps off oily head.
Background technique
The reciprocating type water injection pump of plunger is the capital equipment of oilfield exploitation water filling operation, the retaining oil head of conventional reciprocating formula water injection pump, bent axle are single oil sealing sealing, promptly it is sealed by one outside framework oil seal, sealing effect is undesirable, thereby cause occurring oil leakage phenomenon, shorten the working life of water injection pump, reduce pump efficiency.
The model utility content
In order to overcome retaining oil head, the crankshaft seal weak effect of existing reciprocating type water injection pump, cause occurring oil leakage phenomenon, shorten the working life of water injection pump, reduce the deficiency of pump efficiency, the utility model provides a kind of reciprocating type water injection pump to keep off oily head.
The technological scheme that its technical problem that solves the utility model adopts is: reciprocating type water injection pump keeps off oily head, comprise bent axle, a retaining oil body, outside framework oil seal, pressure cap, a retaining oil body is fixedly mounted on the casing, on a retaining oil body endoporus, the bent axle spindle nose cylindrical outside framework oil seal, packing ring, outside framework oil seal, pressure cap is installed successively axially from inside to outside.Outside framework oil seal is a lips formula outside framework oil seal.
The beneficial effects of the utility model are, and are rational in infrastructure, the reliability and the life-span of having improved oil seal structure, prolonged the Mean time to failure of pump group.
Description of drawings
Fig. 1 is that the reciprocating type water injection pump of the utility model keeps off oily header structure schematic representation.
Among the figure: 1. keep off oil a body, 2. outside framework oil seal, 3. packing ring, 4. bent axle, 5. pressure cap.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
The reciprocating type water injection pump of the utility model keeps off oily head, comprises bent axle 4, a retaining oil body 1, outside framework oil seal 2, pressure cap 5, and a retaining oil body 1 is fixedly mounted on the casing.On a retaining oil body 1 endoporus, the bent axle 4 spindle nose cylindricals outside framework oil seal 2, packing ring 3, outside framework oil seal 2, pressure cap 5 are installed successively axially from inside to outside, pressure cap 5 adopts thread connecting mode to fixedly connected with a retaining oil body 1 with a retaining oil body 1.Outside framework oil seal 2 is a lips formula outside framework oil seal.
The reciprocating type water injection pump of the utility model keeps off oily head, rational in infrastructure, the oil circuit that the lubricant oil that leaks out by the first road outside framework oil seal is made up of a packing ring and a retaining oil body is back in the crankcase, avoided lubricant oil overheap between the twice oil sealing, the reliability and the life-span of oil seal structure have been improved, prolong the Mean time to failure of pump group, reduced the labor intensity of pump group maintaining, improved pump group water filling efficiency of operation.
Claims (2)
1. a reciprocating type water injection pump keeps off oily head, comprise bent axle, a retaining oil body, outside framework oil seal, pressure cap, a retaining oil body is fixedly mounted on the casing, it is characterized in that: on a retaining oil body (1) endoporus, bent axle (4) the spindle nose cylindrical outside framework oil seal (2), packing ring (3), outside framework oil seal (2), pressure cap (5) are installed successively axially from inside to outside.
2. reciprocating type water injection pump according to claim 1 keeps off oily head, it is characterized in that: described outside framework oil seal (2) is a lips formula outside framework oil seal.
