Dual-core super-pressure pump with spare supercharger

Abstract

The invention relates to a dual-core super-pressure pump with a spare supercharger. The dual-core super-pressure pump with the spare supercharger comprises a first supercharger, a second supercharger,a first hydraulic control valve, a second hydraulic control valve, a hydraulic switching valve and a water circuit switching valve. An opening A pipeline of the hydraulic switching valve is connectedto one end of the first hydraulic control valve, and the other end pipeline of the first hydraulic control valve is connected with a hydraulic opening of the first supercharger. A water outlet pipeline of the first supercharger is connected with an opening A of the water circuit switching valve, and an outlet pipeline of the water circuit switching valve is connected with an inlet of an energy accumulator. An opening B pipeline of the hydraulic switching valve is connected with the one end of the second hydraulic control valve, and the other end pipeline of the second hydraulic control valveis connected with a hydraulic opening of the second supercharger. A water outlet pipeline of the second supercharger is connected to an opening B of the water circuit switching valve. When one of theturbochargers is detected to be in trouble, a hydraulic circuit valve and a water circuit valve operate simultaneously, and the hydraulic circuit and the water circuit are switched to another turbocharger simultaneously. At the same time, the hydraulic circuit and the water circuit of the fault turbocharger are shut down for maintenance or replacement, and the use is convenient.

Description

technical field [0001] The invention belongs to the field of ultra-high pressure water cutting of high-pressure water jet technology, and in particular relates to a dual-core ultra-high pressure pump with a spare supercharger, which is an ultra-high pressure generator device capable of completing online uninterrupted automatic switching. Background technique [0002] At present, the ultra-high pressure generator products on the market generally use a single supercharger, that is, only one supercharger is used in the entire system, which basically consists of a motor, a hydraulic pump set, a hydraulic reversing valve, a single supercharger, and an energy storage unit. It is the most common type of ultra-high pressure generator in ultra-high pressure waterjet cutting machines, and it has the characteristics of small size and low price. The supercharger in the ultra-high pressure generator product is the core component, but due to various reasons, the supercharger often has fai...
