High-pressure cleaning machine for hot water pump

Abstract

The invention relates to a high-pressure cleaning machine for a hot water pump. The cleaning machine comprises a low-pressure end hot water supply device, a high-pressure end hot water supply device, a high-pressure hot water application object and a residual liquid collecting device, wherein the water outlet of the low-pressure end hot water supply device is communicated with the water inlet of the high-pressure end hot water supply device; the water outlet of the high-pressure end hot water supply device is communicated with the high-pressure hot water application object through a high-pressure hot water pipeline; residual liquid which passes through the high-pressure hot water application object is communicated with the residual liquid collecting device through a residual liquid collecting pipeline; and the residual liquid collecting device is communicated with the water inlet of the low-pressure end hot water supply device through a residual liquid circulating pipeline. A low-pressure part is heated, the selectable range of a heater is wide, the heater can be freely selected according to raw material supply and safety and economy achieving conditions, and operability is high; and a low-pressure end heats liquid, and the pressure, flow and temperature of the liquid are easy to control.

Description

technical field [0001] The invention relates to a washing machine, in particular to a hot water pump high-pressure washing machine. Background technique [0002] At present, the existing cleaning machines all adopt the treatment method of pressurizing first and then heating, that is, heating at the high-pressure end, and the optional range of heating modes is very small. It is very difficult to realize the controllability of the pressure, temperature and flow of the liquid at the high temperature and high pressure end; the original cost of the equipment and the cost of later use and maintenance are high, the economy is poor, and the overall safety is poor; [0003] Heating at the high-pressure end, the pipeline and valve at the connection between the heater and the hot liquid pipeline are under high pressure and frequently change cold and hot alternately, where the failure rate of the pipeline and valve is high, and the cost of use and maintenance is high; The cost of liqui...
