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

Abstract

The present invention, high pressure water jet multiplex switching control method and multiple position automatic cleaner, features the electrically controlled overflow valve connected serially between the high pressure water pump output pipeline and the high pressure multiway valve for relieving pressure of the pipeline. The electrically controlled overflow valve and the electrically controlled cut-off valve are matched to realize the automatic on-off switching of the pipe branches without need of stopping the high pressure water pump. The present invention realizes protection against high pressure impact to increase the service life of the equipment, has the advantages of simple structure, comprehensive functions, stable performance, reliable control, wide application range, etc, and may be used widely in high pressure water jet cleaning job in coke chemical, metallurgical, chemical 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...
