Description

The utility model relates to the accessory equipment of vacuum pumps, in particular to the head design.

The proposed head is designed to ensure the tightness of the working chamber of the vacuum pump and create a vacuum.

Currently, it is known that when creating a vacuum in a vacuum toilet during operation, corrosion of the inner surfaces of the head body and the cover of the vacuum pump occurs due to an aggressive working environment, which subsequently leads to their non-maintainability.

The closest technical solution to the proposed head is a head for a vacuum pump, consisting of a body and a cover, in which threaded through holes are made, for connecting the vacuum and exhaust pipes. (https://ulvac.org/standartnye-membrannye-nasosy/232-da-120s-membrannyj-nasos.html DA-120S diaphragm pump).

In the known design, all parts of the head are made of aluminum alloy.

The disadvantage of the known head for a vacuum pump is weak corrosion resistance when working as part of the vacuum equipment of a vacuum toilet.

The technical result solved by the proposed utility model is the creation of a head design for a vacuum pump, which has increased corrosion resistance, thereby ensuring long-term operation of the vacuum equipment.

The technical result in the proposed utility model is achieved by creating a head for a vacuum pump, consisting of a body with threaded through holes for connecting the vacuum and exhaust pipes, and a cover, in which, according to the utility model, the body and the cover are made as a single piece of Corrosion-resistant synthetic material, the head is equipped with a plate made of stainless steel, located at the bottom of the body and having mounting positions for suction and discharge valves.

The proposed utility model, while maintaining its technical characteristics, is not subject to corrosive wear due to the aggressive working vacuum toilet during operation.

The proposed utility model also has a number of additional advantages, namely:

- reduction of technological complexity;

- reduction of labor intensity and duration of the head production, which is aimed at increasing reliability and durability;

The essence of the proposed utility model is illustrated by the description below and drawings, where

FIG. 1 shows a proposed vacuum pump head;

FIG. 2 shows a top view of FIG. one;

FIG. 3 section a-a of FIG. 1 In Fig. 4, bottom view of the head head The head for the vacuum pump consists of a housing 1 with through-threaded holes 2 for connecting the vacuum and exhaust lines, a cover 3 and a plate 4 having mounting locations 5 for the suction and discharge valves.

Body 1 and cover 3 are made in the form of a single piece of corrosion-resistant synthetic material, and plate 4 is made of stainless steel and is installed on the bottom of body 1

Moreover, depending on technological capabilities, a monolithic fluoroplastic processed by milling and drilling or a material with similar properties can be used as a corrosion-resistant synthetic material.

To connect the vacuum and exhaust lines to the housing 1, screw the threaded fittings (not shown in the drawing).

Also, threaded nipples can be used depending on technological tasks and for connection to the second head of the vacuum pump.

Suction and discharge valves (not shown in the drawing) are installed in the mounting locations 5 on plate 4, and plate 4 is attached to the body 1 with hardware made of stainless steel.

The prototype of the proposed head for the vacuum pump was tested on the Ulvac DA-120S vacuum pump and it was proved that the product can be reused, due to the elimination of the need for disassembly or complete dismantling and replacement of head parts due to corrosive wear.

Claims (1)

A head for a vacuum pump, consisting of a body with through threaded holes designed to connect the vacuum and exhaust lines, and a cover, characterized in that the body and the cover are made in the form of a single piece of corrosion-resistant synthetic material, and the head is equipped with a plate having fittings for suction and discharge valves and made of stainless steel.
