Vacuum assistance self-sucking pump truck

Abstract

The invention relates to the field of draining devices and especially relates to a vacuum assistance self-sucking pump truck. The device comprises an axle and a vacuum assistance self-sucking pump setmounted on the axle; the vacuum assistance self-sucking pump set comprises a chassis and a vacuum assistance system fixedly mounted on the chassis; an air-cooled diesel engine and a water pump; the vacuum assistance system comprises a vacuum pump and a vacuum pump fuel tank, and the vacuum pump is driven by the air-cooled diesel engine; a suction port of the vacuum pump is connected to a steam-water separation device located at the upper part of a water pump through a wire hose; the air-cooled diesel engine is connected to the water pump through a toothed connecting plate, wherein the toothedconnecting plate comprises an inner disk and an outer disk; the outer wall of the outer disk meshes with the diesel engine flywheel; the inner wall of the outer disk is provided with internal teeth,and the outer disk is provided with the inner disk; the outer wall of the inner disk is provided with external teeth, the external teeth and the inner teeth are in mesh with each other, and the innerwall of the inner disk is connected to the pump shaft through a coupling. The device provided by the invention has convenient installation and maintenance and high drainage efficiency.

Description

technical field [0001] The invention relates to the field of drainage equipment, in particular to a vacuum-assisted self-priming pump truck. Background technique [0002] Drainage equipment is used for water accumulation on urban roads or drainage during flood seasons, and pump trucks are generally used for drainage equipment. Traditional pump trucks are driven by diesel engines to pump water. A coupling is used between the diesel engine and the water pump. Connection, and the coupling has a relatively high requirement for matching accuracy, otherwise the phenomenon of shaft jumping may occur, which is very inconvenient for installation and maintenance, and relying on the suction of the water pump itself, the water discharge is slow, which affects the drainage efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a vacuum-assisted self-priming pump vehicle with convenient installation and maintenance and hi...
