Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] As shown in Fig. 1 and Fig. 2, the present invention comprises engine 2, high-pressure pump 1, throttle control valve and spray gun 12, and the first liquid outlet of the high-pressure pump 1 driven by engine 2 enters through high-pressure pipeline 5 and overflow valve. The liquid port is connected, the liquid inlet of the high pressure pump 1 and the overflow valve are connected through the unloading pipe 6 and then connected to the water source 4 through the water inlet pipe 3, and the throttle control valve is connected with the engine throttle 10 through a steel wire rope 9. The overflow valve is an overflow unloading valve 7, the liquid outlet of the overflow unloading valve 7 is connected to the spray gun 12 through the liquid outlet pipeline 11, and the second liquid outlet of the high pressure pump 1 is equipped with a throttle c...

Abstract

The invention discloses a throttle control system for a hi-pressure cleaner. The hi-pressure pump of the system is driven by an engine, the outlet of the hi-pressure pump is connected with the inlet of an overflow downloading valve through a high-pressure pipe; the hi-pressure pipe and the hi-pressure pump are connected by an unloading pipe; the outlet of the overflow unloading valve is connected with a spray gun through a fluid-out pipeline; another outlet of the hi-pressure pump is provided with a throttle control valve, which is connected with the throttle of an engine through a steel wire. When the spray gun is off, the outlet pressure of the pump unloads rapidly, meanwhile the throttle is adjusted so that the engine speed rapidly drops to idle speed; when the spray gun is on, the outlet pressure of the pump increases rapidly to operation pressure, meanwhile the engine speed rises to hi-speed state. And when an operator adjusts the cleaning pressure, the throttle of the engine can be automatically adjusted to a position corresponding to the cleaning pressure.

Description

technical field [0001] The invention relates to a cleaning device, in particular to a throttle control system of a high-pressure cleaning machine. Background technique [0002] During the cleaning process, no matter whether the spray gun is turned on or not, the engine is always running at high speed, and the pump outlet is always kept at high pressure, which not only wastes energy, but also greatly reduces the service life of the pump because the pressure at the pump outlet cannot be unloaded. Therefore, it is necessary to develop a high-pressure cleaner throttle control system, so that the high-pressure cleaner can automatically adjust the speed of the engine and the pump outlet pressure according to the work needs. [0003] The US patent discloses a throttle control system for a high-pressure washer (patent No. 5,174,723), the schematic diagrams of which are shown in FIGS. 3 and 4 . The high-pressure pump 30 is driven by an engine 31 , and the water inlet of the high-pre...
