Abstract

The utility model relates to booster pumps of oil exploitation, in particular to a novel oil leakage preventive booster pump. The novel oil leakage preventive booster pump comprises a booster pump body. A shaft hole is formed in the booster pump body, a connecting rod is arranged on the booster pump body through the shaft hole, an annular groove surrounding the connecting rod is formed in the outer surface of the booster pump body, the annular groove is provided with inner threads, a sealing ring is arranged in the annular groove, and an annular pressing cap is arranged in the annular groove through the threads. The novel oil leakage preventive booster pump is characterized in that a spring is arranged between the pressing cap and the sealing ring, a plurality of concave grooves are formed in the periphery of the pressing cap, and a locating bolt is arranged in a threaded hole in the booster pump body and is clamped in the concave groove. The novel oil leakage preventive booster pump is simple in structure and convenient to operate. Due to the fact that the spring tightly presses the sealing ring, the number of screwing times of the pressing cap is reduced, sealing effects are good, the service life of the sealing ring can be further prolonged, and production cost is reduced.

Description

A kind of novel anti-leakage oil suction booster
Technical field
The utility model relates to the suction booster of petroleum production, particularly relates to a kind of novel anti-leakage oil suction booster.
Background technique
Suction booster is feedwater supercharging equipment important in petroleum production.Fill machine oil in the suction booster casing, it is a major reason that causes suction booster to damage that machine oil is revealed from connecting rod.At present, the sealing of the connecting rod of suction booster is to adopt the axis hole periphery outside the suction booster casing to be provided with annular groove, is equipped with seal ring in annular groove, and seal ring is equipped with cover plate outward; What also have is designed to: annular groove is provided with internal thread, and packing is housed in annular groove, and the ring pressure cap is arranged in annular groove by screw thread.There are many defectives in such design: sealing effect is poor, and the seal ring replacement cycle is short, and seal ring is is easily worn and torn by connecting rod, between seal ring and connecting rod, the gap is arranged, and causes oil leakage.
Summary of the invention
The purpose of this utility model is the technological scheme that a kind of novel anti-leakage oil suction booster is provided for the deficiencies in the prior art, and this technological scheme good sealing effect, sealing material replacement cycle are long, reaches the purpose of safety in production.
the utility model is achieved in that a kind of novel anti-leakage oil suction booster, it has the suction booster body, on the suction booster body, axis hole is arranged, connecting rod is arranged on the suction booster body by axis hole, this external surface of suction booster pressed on ring is provided with annular groove around connecting rod, annular groove is provided with internal thread, seal ring is housed in annular groove, the ring pressure cap is contained in annular groove by screw thread, it is characterized in that, between pressure cap and seal ring, spring is housed, the periphery of described pressure cap is provided with several Baltimore grooves, holding down bolt is installed in screw on the suction booster body and is stuck in Baltimore groove.
The beneficial effects of the utility model: the utility model is simple in structure, and is easy to operate, and spring compresses seal ring, reduces the number of times that turns to pressure cap, and good sealing effect, can extend again the service time of seal ring, reduced cost of production.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of pressure cap in Fig. 1.
Wherein, 1-connecting rod, 2-pressure cap, 3-annular groove, 4-seal ring, 5-axis hole, 6-suction booster body, 7-screw, 8-holding down bolt, 9-spring, 10-Baltimore groove.
Embodiment
Below in conjunction with accompanying drawing, concrete structure of the present utility model and principle are described further.
as shown in the figure, novel anti-leakage oil suction booster of the present utility model, it has suction booster body 6, axis hole 5 is arranged on suction booster body 6, connecting rod 1 is arranged on suction booster body 6 by axis hole 5, be provided with annular groove 3 around connecting rod 1 on suction booster body 6 outer surfaces, annular groove 3 is provided with internal thread, seal ring 4 is housed in annular groove 3, ring pressure cap 2 is contained in annular groove 3 by screw thread, it is characterized in that, between pressure cap 2 and seal ring 4, spring 9 is housed, the periphery of described pressure cap 2 is provided with several Baltimore grooves 10, holding down bolt 8 is installed in screw 7 on suction booster body 6 and is stuck in Baltimore groove 10.
Working principle of the present utility model is such: seal ring 4 is housed in annular groove 3, ring pressure cap 2 is arranged in annular groove 3 by screw thread, between ring pressure cap 2 and seal ring 4, spring 9 is housed, seal ring 4 gets up the gap sealing between connecting rod 1 and axis hole 5.Suction booster is in running, and seal ring 4 can be worn, but the pressure of spring 9 continues to be pressed on seal ring 4, makes to continue sealing between seal ring 4 and connecting rod 1.When the pressure of spring 9 becomes very little, turn the further holddown spring 9 of pressure cap 2 with spanner.Because suction booster can vibrate in running, if do not carry out spacing to ring pressure cap 2, ring pressure cap 2 will oneself become flexible, in order to change this deficiency, design overcomes like this: the periphery of ring pressure cap 2 is provided with several Baltimore grooves 10, and holding down bolt 8 is installed in screw 7 on suction booster body 6 and is stuck in Baltimore groove 10.

Claims (1)

1. novel anti-leakage oil suction booster, it has the suction booster body, on the suction booster body, axis hole is arranged, connecting rod is arranged on the suction booster body by axis hole, this external surface of suction booster pressed on ring is provided with annular groove around connecting rod, annular groove is provided with internal thread, seal ring is housed in annular groove, the ring pressure cap is contained in annular groove by screw thread, it is characterized in that, between pressure cap and seal ring, spring is housed, the periphery of described pressure cap is provided with several Baltimore grooves, and holding down bolt is installed in screw on the suction booster body and is stuck in Baltimore groove.
