Sanitation vehicle low-pressure water path with adjustable flushing width

Abstract

The invention discloses a sanitation vehicle low-pressure water path with an adjustable flushing width. The sanitation vehicle low-pressure water path comprises a water tank, a water pump, a sprinklerand a bypass water path. The water tank is connected with a water inlet of the water pump through a connecting pipeline, and a water outlet of the water pump is connected with one or more sprinklersthrough connecting pipelines. The bypass water path capable of controlling opening and closing is arranged between the water pump water outlet and the water tank. The bypass water path is additionallyarranged at the water outlet of the water pump of the low-pressure water path; when the low-pressure water path normally operates, the bypass water path is closed, the water pump normally supplies water to the sprinklers through the pipelines, and when the water spraying pressure needs to be changed, the bypass water path can be controlled to be opened, so that the pressure of the sprinklers is changed, the real-time adjustment of the flushing width of the low-pressure water path of the sanitation vehicle is realized, and the application scene is expanded.

Description

technical field [0001] The invention relates to the field of sanitation vehicles, in particular to a low-pressure waterway system for sanitation vehicles. Background technique [0002] In the existing low-pressure water system scheme of sanitation vehicles, a centrifugal water pump is used to extract clean water from the vehicle-mounted water tank, the water outlet of the water pump is directly connected to the sprinkler through a cut-off valve, and the water pump is driven by the chassis power take-off mechanism. When the sanitation vehicle with this structure is in operation, the flushing width of the sprinkler is only determined by the rotation speed of the water pump, and since the water pump is driven by the chassis power take-off mechanism, subject to the requirements of chassis driving, the chassis engine and gearbox need to be properly operated. RPM operation, so the flush width of the sprinkler cannot be adjusted effectively. When the sanitation vehicle encounters ...

AI Technical Summary

Problems solved by technology

When the sanitation vehicle with this structure is working, the flushing width of the sprinkler is only determined by the speed of the water pump, and since the water pump is driven by the power take-off mechanism of the chassis, it is limited by the driving requirements of the chassis. RPM operation, so the flushing width of the sprinkler cannot be effectively adjusted

When the sanitation vehicle encounters pedestrians on the side of the road or other working conditions that need to adjust the flushing width, it cannot meet the use requirements
