Implementation of a utility model

The device operates as follows. At the beginning of the cycle, the electromagnetic valve (6) is open, the low-pressure water pump (2) from the water treatment (1) through the low-pressure check valve (4) pumps clean water into the 1st chamber of the 1st hydraulic accumulator (5) to a certain pressure (about 4 bar), which is measured by the low-pressure sensor (3) and the pump is switched off. The electromagnetic valve (6) closes, the high-pressure oil pump (8) is switched on and from the hydraulic fluid tank (7) pumps oil under pressure (up to 80 bar) into the 2nd chamber of the 1st hydraulic accumulator (5), displacing water from the 1st chamber of the 1st hydraulic accumulator (5), the pressure is measured by the high-pressure sensor (11). Water enters the 1st chamber of the 2nd hydraulic accumulator (10) through the high-pressure check valve (9), in the 2nd chamber of which there is compressed gas, and enters the spray nozzles (12). The high-pressure pump is switched off. Then the cycle is repeated, maintaining the required pressure of ultra-pure water in the 2nd hydraulic accumulator and spray nozzles.

Thus, reduced wear (increased reliability) of the high-pressure pump and low noise level of the high-pressure water pump are achieved by using oil as the working fluid of the high-pressure pump.
