Problems solved by technology

[0009] Although the existing high-pressure water descaling system can choose a high-pressure pump with a smaller flow rate, the investment is less; but the disadvantages are more obvious, requiring a larger workshop, heavy equipment weight, low automation, and requiring special personnel to operate, and the storage tank 9 Water and gas accidents are prone to occur, the system pressure fluctuates greatly, and the system pressure cannot be adjusted adaptively according to the material and temperature of the slab. Control the number of opening and closing nozzles according to the width of the rolled piece, resulting in waste of energy

Abstract

The present invention relates to a high-pressure water scale-removing system. It includes cleaning filter and minimum flow valve group. After the described self-cleaning filter successively are set diaphragm type water storage tank and descaling pump group, and after the described minimum flow valve group successively are set low-pressure precharging valve group, on-machine descaling sprays, on-maching descaling manifold, high-effective descaling nozzle, descaling tank descaling spray valve group, descaling tank descaling manifold and descaling tank high-effective nozzle. Said invention adopts high-pressure variable frequency speed-regulating technique to raise descaling efficiency.

Description

【Technical field】 [0001] The invention relates to a high-pressure water descaling system adopting frequency conversion technology, wide and narrow descaling control, large-flow SDS type double-shell impeller symmetrically arranged descaling pump, diaphragm type potential storage tank for buffering and vibration reduction, and automatic descaling operation control. 【Background technique】 [0002] Glossary explanation: L1, L2 control system: that is, basic automation level (L1) and process control computer level (L2). The basic automation level includes electrical automation and instrument automation, using PLC system to complete sequence control, sampling of related instruments, and control of actuators. The process control computer level realizes the long-term continuous memory function of various parameters of the unit equipment, and has the ability to respond quickly to the disturbance of the dynamic process. On the one hand, it uses process specifications and mathematica...
