Description

A new water sealing device for plunger pump

Technical Field

The utility model is a novel water sealing device for a plunger pump, and relates to the technical field of plunger pumps.

Background Art

The plunger pump is an important device in the hydraulic system. It relies on the reciprocating motion of the plunger in the cylinder to change the volume of the sealed working chamber to achieve oil suction and oil pressure. The plunger pump has the advantages of high rated pressure, compact structure, high efficiency and convenient flow regulation. The plunger pump includes many types. The ceramic plunger of the ceramic plunger pump will generate heat when it moves up and down during operation, so circulating cooling water is required to cool the ceramic plunger throughout the process. The cooling water cools the ceramic plunger during the pressurized water. However, due to the up and down movement trajectory of the ceramic plunger, a large amount of cooling water will overflow when cooling the ceramic plunger, and the sealing effect needs to be improved. In order to solve the problem of cooling water overflow, it is necessary to propose a new water sealing device for the plunger pump for improvement.

As a further improvement, a coolant inlet and a coolant outlet for cooling water circulation are respectively provided on both sides of the transition sleeve.

As a further improvement, connection holes are provided at the bottom of the transition sleeve and the upper side of the pump body, and are fastened by bolts.

A further improvement is that a sealing ring is provided on the transition sleeve and in close contact with the upper side of the pump body.

A further improvement is that a mounting groove is provided inside the connection opening between the upper side of the pump body and the ceramic plunger, and a rubber waterproof gasket is installed inside the mounting groove, and the top of the rubber waterproof gasket fits with the bottom of the water pressure ring.

Compared with the prior art, the utility model has the following advantages:

The utility model has a simple and ingenious structure. A transition sleeve is arranged on the upper side of the water pressure ring. A certain closed space is arranged inside the transition sleeve, which can effectively prevent the cooling water from overflowing. A sealing ring is connected to the transition sleeve and a rubber waterproof gasket is arranged at the opening on the upper side of the pump body, which can achieve a double connection sealing effect. The installation of the transition sleeve is also relatively simple and convenient, and it has a more positive and beneficial use effect than the prior art.

DETAILED DESCRIPTION

In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

Please refer to Figure 1. The utility model provides a technical solution for a new water sealing device for a plunger pump: it includes a pump body 1 and a ceramic plunger 2 movably arranged on the pump body 1. The ceramic plunger 2 is provided with a water pressure ring 3 and a transition sleeve 4, and the water pressure ring 3 and the transition sleeve 4 are both installed at the connection between the upper side of the pump body 1 and the ceramic plunger 2. The water pressure ring 3 is adapted to be arranged inside the transition sleeve 4, so that the transition sleeve 4 is installed above the water pressure ring 3 to make it a closed space. In this way, when the ceramic plunger 2 moves up and down, the cooling water can directly cool the ceramic plunger 2, and the cooling water is not easy to overflow.

In the above technical solution, a coolant inlet 5 and a coolant outlet 6 for cooling water to flow are respectively provided on both sides of the transition sleeve 4 to facilitate the circulation of cooling water.

In order to facilitate the disassembly, assembly and replacement of the transition sleeve 4, connecting holes 8 are opened at the bottom of the transition sleeve 4 and the upper side of the pump body 1, and are fastened by bolts.

In order to improve the airtightness between the transition sleeve 4 and the pump body 1, a sealing ring 9 is fitted between the transition sleeve 4 and the pump body 1, and a mounting groove 7 is provided on the inner side of the connection opening between the upper side of the pump body 1 and the ceramic plunger 2, and a rubber waterproof gasket 10 is installed on the inner side of the mounting groove 7. The top of the rubber waterproof gasket 10 is fitted with the bottom of the water pressure ring 3, and the overall airtightness is improved through the double connection of the sealing ring 9 and the rubber waterproof gasket 10.

It should be noted that the utility model is a new type of water sealing device for a plunger pump, which mainly improves the above-mentioned structure.
