Problems solved by technology

[0005] As a result, not only the suction system of the sewage suction truck becomes extremely large and occupies a large space, but once the oil-gas separator is used and maintained improperly, it will cause the sewage suction pump to spray oil, which will cause harm to the health of users and the environment

Embodiment 1

[0039] Such as Figure 1-3 As shown, the four-way valve 6 includes four valve ports, with the upper valve port being the first valve port, and the second valve port, the third valve port and the fourth valve port in turn clockwise.

[0040] The air inlet of the dry vacuum pump 8 communicates with the second valve port through the second pipe 7, and the air outlet communicates with the fourth valve port through the third pipe 5. The third valve port of the four-way valve 6 communicates with the atmosphere through a safety pipeline. The first valve port of the four-way valve 6 communicates with the sewage suction tank 2 through the first pipe 3. The first pipe 3 is provided with a safety valve 9, and the second pipe 7 is provided with a water vapor separator 10.

[0041] The upper part of the sewage suction tank 2 is provided with an anti-overflow valve, and the anti-overflow valve is in communication with the first pipe 3. The sewage suction tank 2 and the sewage suction pipe 1 ar...

Embodiment 2

[0046] A dry vacuum pump working system, reference figure 1 , No sewage suction tank 2, sewage suction pipe 1 and sewage pipe 4 are provided. The working end of the first pipe 3 is used to charge and exhaust air cushions, air cushion amusement parks, hovercraft, etc.

Embodiment 3

[0048] A suction working system. According to Embodiment 2, the working end of the first pipe 3 is connected to the valve port of a three-way valve. The other two valve ports of the three-way valve are respectively connected to two suction tanks. By switching the state of the three-way valve, the first pipe 3 can be connected to different suction tanks respectively.

[0049] The structure of the suction tank is similar to that of the sewage suction tank, but it is much smaller than the volume of the sewage suction tank. The upper part of the suction tank is connected with a suction pipe for suction, and the lower part of the suction tank is connected with a discharge pipe for discharging. The discharge pipe is equipped with a ball valve, which is closed during suction and opened during discharge.

[0050] It is also possible to provide multiple rows of solenoid valves, the first pipe 3 is connected to one end of the solenoid valve, and the other end of the solenoid valve is respec...

Abstract

The invention relates to a dry vacuum pump work system. The dry vacuum pump work system comprises a dry vacuum pump and a four-way valve. When the four-way valve is in a first work state, a first valve opening and a second valve opening communicate, and a third valve opening and a fourth valve opening communicate. When the four-way valve is in a second work state, the first valve opening communicates with the fourth valve opening, and the second valve opening communicates with the third valve opening. A first pipeline communicates with the first valve opening, and the other end of the first pipeline is a work end. A second pipeline communicates with the second valve opening, and the other end of the second pipeline communicates with an air inlet of the dry vacuum pump. A third pipeline communicates with the fourth valve opening, and the other end of the third pipeline communicates with an air outlet of the dry vacuum pump. A safety pipeline communicates with the third valve opening, and the other end of the safety pipeline communicates with the air. According to the dry vacuum pump work system, the dry vacuum pump is adopted, no oil exists in a cavity, the expense and space of arranging an oil-gas separator are saved, and the hidden danger that oil and other medium react with sewage and dirt, and the system performance is influenced is avoided; and the dry vacuum pump is simplein structure and convenient to repair, and the maintenance and repairing difficulty is reduced.

Description

Technical field [0001] The invention relates to the field of fluid pipeline pumping, in particular to a dry vacuum pump working system. [0002] The invention also relates to a dirt suction working system and a material suction working system. Background technique [0003] At present, the sewage suction truck is a new type of sanitation vehicle that is used to collect, transfer, clean and transport sludge or liquid to avoid secondary pollution. Among them, the vacuum sewage suction truck can not only self-suction and discharge, but also has a fast working speed and a high capacity. Large and easy to transport, so it is mainly suitable for collecting and transporting liquid substances such as feces, mud or crude oil. [0004] In practical applications, due to the harsh working environment of the vacuum sewage suction truck, and the level of vacuum has a greater impact on the overall performance of the sewage suction truck, the sewage suction truck is often assembled in the suction di...
