Abstract

The utility model discloses a plunger which is installed in a high pressure cleaning machine and used for producing of high pressure water flow. The plunger comprises a plunger main body which is in a hollow structure. As a common sense, for parts in the same size, the mass of the hollow structure can be decreased in a certain extent relative to the mass of a solid structure. So, according to the plunger, the mass of the plunger is lightened so that the plunger can be conveniently held through machinery in the process of machining. Due to the separated design of the plunger main body and a plunger cover, a prior handmade and single processing method is changed into a processing method of completely automatic machinery production, and therefore processing efficiency is greatly improved and processing difficulty is decreased. Besides, due to the fact that the hollow structure is adopted, the needed materials of manufacture are decreased, and manufacturing cost is reduced. In conclusion, due to the fact that the hollow structure is adopted through the plunger, the problems that the machining operation of the plunger is difficult and manufacturing cost is high can be solved.

Description

A kind of plunger

Technical field

The utility model relates to the jetting machine equipment technical field, more particularly, and particularly a kind of plunger.

Background technique

Jetting machine is to make high-pressure plunger pump produce the machine that high pressure water washes body surface by power plant.It can be peeled off dirt, washes away, and reaches the purpose on cleaning of objects surface.Because be to use water jets under high pressure cleaning dirt, so high-pressure wash also is one of cleaning mode of universally acknowledged most scientific, economy, environmental protection.

One of of paramount importance parts are exactly plunger in the jetting machine, and plunger is the critical piece that produces high-pressure water flow.In the prior art, the production of plunger is to adopt the embryo spare of solid integral body to process, and its quality of processing is larger, has caused comparatively difficulty of plunger processing, causes work efficiency lower.And, adopting solid construction, manufacture cost also can be corresponding higher.

In sum, how to solve comparatively difficulty of plunger machining operation, the problem that manufacture cost is higher becomes those skilled in the art's problem demanding prompt solution.

The model utility content

The technical problems to be solved in the utility model is for providing a kind of plunger, and this plunger can solve comparatively difficulty of plunger machining operation, the problem that manufacture cost is higher by its structural design.

For solving the problems of the technologies described above, the utility model provides a kind of plunger, is installed in the jetting machine, for generation of high-pressure water flow, comprises piston body, and described piston body is hollow-core construction.

Preferably, an end of described piston body removably is provided with cover of plunger.

Preferably, an end of described piston body offers mounting hole, and described cover of plunger is inserted in the described mounting hole.

The utility model provides a kind of plunger, is installed in the jetting machine, for generation of high-pressure water flow, comprises piston body.In the utility model, piston body has adopted hollow-core construction.As a kind of general knowledge as can be known, for measure-alike parts, its hollow-core construction is for solid construction, and quality can descend on certain degree to some extent.So, in the utility model, the plunger quality lightens, being convenient to mechanical adding when machining holds, because piston body and cover of plunger split design, processing mode changes full-automatic machinery production into by the manual single processing of original needs, thereby greatly improves work efficiency.Thereby reduce its difficulty of processing, improve work efficiency.And owing to adopting hollow-core construction, it is made required material and reduces the manufacture cost reduction.In sum, the utility model can solve comparatively difficulty of plunger machining operation, the problem that manufacture cost is higher owing to having adopted hollow-core construction.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to the accompanying drawing that provides other accompanying drawing.

Embodiment

Core of the present utility model is for providing a kind of plunger, and the piston body of this plunger adopts the hollow-core construction design, by this structure, can solve comparatively difficulty of plunger machining operation, the problem that manufacture cost is higher.

In order to make those skilled in the art understand better the technical solution of the utility model, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Please refer to Fig. 1, Fig. 1 is the structural representation of plunger among a kind of embodiment of the utility model.

The utility model provides a kind of plunger, is installed in the jetting machine, for generation of high-pressure water flow, comprises piston body 1.In the utility model, piston body 1 has adopted hollow-core construction.As a kind of general knowledge as can be known, for measure-alike parts, its hollow-core construction is for solid construction, and quality can descend on certain degree to some extent.So, in the utility model, the plunger quality lightens, and is convenient to mechanical adding and holds when machining, thereby reduce its difficulty of processing, improves work efficiency.And owing to adopting hollow-core construction, it is made required material and reduces the manufacture cost reduction.In sum, the utility model can solve comparatively difficulty of plunger machining operation, the problem that manufacture cost is higher owing to having adopted hollow-core construction.

Particularly, an end of piston body 1 removably is provided with cover of plunger 2.

In the above-described embodiments, adopt socket connection between piston body 1 and the cover of plunger 2, particularly, an end of piston body 1 offers mounting hole, and cover of plunger 2 is inserted in the mounting hole.In order to improve the connection reliability between piston body 1 and the cover of plunger 2, preferably, adopt between cover of plunger 2 and the piston body 1 to be threaded.
