High pressure water jet flow multiway switch control method and multiple work station automatic cleaner

Abstract

The invention discloses a high-pressure water jet multi-channel switching control method and a high-pressure water jet multi-station automatic cleaning device. It is characterized in that an electric control overflow valve capable of releasing the pressure in the pipeline is connected in series between the output pipeline of the high-pressure water pump and the high-pressure multi-way valve block. Under the condition that the high-pressure water pump does not have to stop working, the automatic on-off switching between the branches is realized through the mutual cooperation of the electric control overflow valve and the electric control stop valve. An unloading link is added before each action of the electric control globe valve, that is, the electric control overflow valve must first return to the overflow state, so that the electric control globe valve operates under low pressure, realizes anti-high pressure impact protection, and improves the service life of the equipment. It has the advantages of simple structure, complete functions, stable performance, reliable control and wide applicable pressure range. It has good promotion and use value. It is mainly used in high-pressure water jet cleaning and operation in coking, metallurgy, chemical industry, mining and other fields.

Description

technical field [0001] The invention discloses a high-pressure water jet multi-channel switching control method and a high-pressure water jet multi-station automatic cleaning device, belonging to the technical field of high-pressure water jet operation and cleaning of industrial equipment. Background technique [0002] High-pressure water jet cleaning technology has been well applied in various fields of industrial production, and its main use method is manual single-station operation or multi-station simultaneous operation. For ultra-high pressure water jet cleaning and operations with a pressure range of 50MPa-100MPa and above, it is quite difficult to realize automatic on-off switching between multiple branches, thereby realizing program control. The reason is that when the high-pressure water pump does not stop working, the on-off switching between multiple high-pressure water branches is realized. The high-pressure water pump and control valve working under high pressur...

Problems solved by technology

For ultra-high pressure water jet cleaning and operations with a pressure range of 50MPa-100MPa and above, it is quite difficult to realize automatic on-off switching between multiple branches, thereby realizing program control.

The reason is that when the high-pressure water pump does not stop working, the on-off switching between multiple high-pressure water branches is realized. The high-pressure water pump and control valve working under high pressure are subjected to high-pressure impact, which will cause system damage.

In addition, for users who use high-pressure water jet operations in the north, the freezing problem of the working medium in winter also restricts the normal use of the equipment

None of the above problems have a good solution
