Embodiment Construction

[0025] 1. High-pressure water jet derusting production line for trucks:

[0026] Including ultra-high pressure pump unit and its power and control system, water pool, ultra-high pressure pump unit includes motor, reducer, frequency converter and ultra-high pressure pump, frequency converter is used to control the motor speed, and then control the ultra-high pressure pump, ultra-high pressure pump The front centrifugal pump and precision filter are installed before the import; the ultra-high pressure pump is connected with high-pressure water jet cleaning equipment through ultra-high pressure hose and control valve. Install without / with a cover, the cover is installed on the outside of the spray rod of the rotary nozzle, and the edge of the cover is fixed with an elastic ring. The casing is connected to the vacuum recovery system. The vacuum recovery system consists of a vacuum pump unit, a vacuum tank, valves and pipelines, and a control system. The vacuum pump and sewage pump...

Abstract

The invention discloses a freight car high pressure water jet derusting production line and a process thereof, comprising high-pressure pump units, the power and control system, a water container and a prepositive centrifugal pump as well as a precise filter positioned in front of the high-pressure pump inlet; the high-pressure pump is connected with high pressure water jet cleaning devices through a high-pressure hose and a control valve. The high pressure water jet cleaning devices refers to the high pressure water rotating nozzle or spray gun. The high pressure water rotating nozzle is provided with a cover or without a cover outside. The cover is communicated with a vacuum recovery system. The sewage in the vacuum tin and the sewage collected are all sent to the water filter recovery system. The production line has the advantages of high derusting efficiency, good effect and dryness on derusting.

Description

technical field [0001] The invention relates to the technical field of high-pressure water jets, in particular to a high-pressure water jet rust removal production line for trucks and a high-pressure water jet rust removal process for trucks. Background technique [0002] The traditional process of surface pretreatment (rust removal) of railway wagons is shot blasting, that is, in a huge sealed space, electric centrifugal impellers are used to throw steel shots and hit the surface to be derusted to achieve the purpose of surface pretreatment. This process has been widely used in locomotive and rolling stock manufacturing plants, and it is precisely this process that has always been troubled by steel shot splash pollution and steel shot treatment. Moreover, because the shot blasting process relies on splash strikes, the quality of derusting is poor, which cannot meet the requirements of the standard for derusting the whole vehicle. The large-area splash pollution of steel sh...
