Abstract
The utility model discloses a recycling device of a high-pressure plunger piston water pump, which comprises a pump body; a return water inlet connector is arranged on a water inlet pipeline of the pump body; a return water outlet connector is arranged on the pump body, on one side of which a plunger piston is mounted; and the return water inlet connector is communicated with the return water outlet connector through a connecting pipe. By virtue of the external return conduit arranged outside the pump body of the traditional high-pressure plunger piston water pump, the utility model has simple and reasonable structure and low manufacturing cost, and can effectively avoid the phenomenon that water flows into a low-pressure area due to the descending of the leak tightness in the continuous use process of the water pump; while overflowing the high-pressure area, water can flow into the water inlet pipeline along the external return conduit, so as to be thoroughly prevented from flowing into an oil tank; moreover, the reliability of the water pump is remarkably improved, and the service life of the water pump is prolonged.
Description
Technical field
The utility model relates to a kind of plunger pump, specifically belongs to a kind of high-pressure plunger water pump reflux.
Background technique
At present, usually being equipped with pressure in the spark-erosion perforating machine is the high-pressure plunger water pump of 6-9MPa, external its inside of this high-pressure plunger water pump of using is provided with the return line that connects zone of high pressure and low pressure area, reliability and serviceability are good in the plunger to-and-fro motion, but this pump body structure complexity, the cost of production costliness is unfavorable for penetration and promotion.With abroad compare, domestic this high-pressure plunger water pump commonly used does not generally possess backflow functionality, plunger to-and-fro motion when pump working, along with the Sealings such as high pressure water seal in the prolongation water pump of service time can wear and tear gradually, cause the sealing of water pump to reduce, the water in the pump housing can be under the high pressure effect flows and progresses into fuel tank to low pressure area more or less, of long duration after water in the fuel tank can get more and more, finally cause fault to take place, water pump can't proper functioning.
Summary of the invention
The utility model purpose is: a kind of high-pressure plunger water pump reflux is provided, it is simple and reasonable, cost of production is low, can effectively solve in the continuous using process of water pump because the water that sealing decline occurs flows into the problem of low pressure area, significantly improve the reliability of water pump, prolong the working life of water pump.
The technical solution of the utility model is: a kind of high-pressure plunger water pump reflux, comprise the pump housing, the intake pipe of the described pump housing is provided with backwater and goes into water swivel, the pump housing that plunger one side is housed is provided with the backwater water output connector, and described backwater is gone between water swivel and the backwater water output connector and is connected by connecting tube.
The utility model has the advantages that:
The utility model is outside equipped with the exteenal reflux pipeline at the pump housing of conventional high-tension plunger water pump, it is simple and reasonable, cost of production is low, can effectively avoid in the continuous using process of water pump because the water that sealing decline occurs flows into the phenomenon of low pressure area, water can flow back in the intake pipe along the exteenal reflux pipeline when water overflows the zone of high pressure, can avoid water to enter in the fuel tank so fully, significantly improve the reliability of water pump, prolong the working life of water pump.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a perspective view of the present utility model;
Fig. 2 is a plan view of the present utility model;
Fig. 3 is a left view of the present utility model.
Wherein: 1 is the pump housing; 2 is intake pipe; 3 go into water swivel for backwater; 4 is the backwater water output connector; 5 is connecting tube.
Embodiment
Embodiment: a kind of high-pressure plunger water pump reflux, as Fig. 1, as 2, shown in Figure 3, a kind of high-pressure plunger water pump reflux comprises the pump housing 1, and the intake pipe 2 of the described pump housing 1 is provided with backwater and goes into water swivel 3, the pump housing 1 that plunger one side is housed is provided with backwater water output connector 4, and described backwater is gone between water swivel 3 and the backwater water output connector 4 and is connected by connecting tube 5.
The utility model is outside equipped with the exteenal reflux pipeline at the pump housing 1 of conventional high-tension plunger water pump, and it is simple and reasonable, and cost of production is low, can effectively avoid in the continuous using process of water pump because the water that sealing decline occurs flows into the phenomenon of low pressure area.When overflowing the zone of high pressure, water can flow in the connecting tube 5 by backwater water output connector 4, going into water swivel 3 by backwater then gets back in the intake pipe 2, can avoid water to enter in the fuel tank so fully, significantly improve the reliability of water pump, make prolong greatly the working life of high-pressure plunger water pump.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other mode of execution.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
