Automatic water diverting device of water pump

Abstract

An automatic water diverting device of a water pump comprises a three-way pipe (3), a ball valve switch (4), a self-sucking device (14), and a self-sucking device tee joint (5), wherein the three-way pipe (3) is fixedly connected with an exhaust funnel (2) of an engine (1), an upper opening is provided with the ball valve switch (4), a lower opening is provided with the self-sucking device (14) and connected with the self-sucking device tee joint (5), and a solenoid connection opening (R) of an inclined pipe is sleeved by an air suction pipe (6) and communicated with a valve switch (Y) of a water inlet end of a water pump (8). A thin inner hole (V) of the bottom end of a self-sucking middle hole (U) of the self-sucking device (14) is through a taper pipe opening (J). When an engine (1) is started, the valve switch (Y) is opened, the ball valve switch (4) is closed, negative pressure is formed in the self-sucking device tee joint (5), and air in the water inlet end of the water pump (8) is sucked into the self-sucking device tee joint (5) and outwards discharged through an exhaust pipe (Q); a water sucking pipe (10) sucks water (S) into an inner cavity of the water pump (8), the ball valve switch (4) is opened, the valve switch (Y) is closed, and the water pump (8) normally works. The automatic water diverting device is convenient to install and use, good in self-sucking effect, and capable of reducing labor intensity and improving efficiency.

Description

technical field [0001] The invention relates to a water pump for pumping water, in particular to a matching device for water diversion. Background technique [0002] Before the water pump starts to run, it needs to divert water into the water pump, discharge the air in the water pump cavity, and then start pumping water. At present, the water diversion device of the water pump generally adopts the hand pressure well piston type and the impeller volute self-suction water method. Recently, the intake system (such as the air filter) of the diesel engine or gasoline engine is also used for water diversion. Although these methods can achieve the water diversion effect, they are generally used. There are problems of relatively high labor intensity of operators and relatively long water diversion time. Water entering the air filter of gasoline or diesel engines may easily cause damage to the main engine, affect the use effect of the water pump, and work efficiency is not high. Co...
