Problems solved by technology

Feedback through the position signal at the end of the stroke is a solution. The position signal can be realized through an external travel switch or proximity switch, but the external travel switch or proximity switch needs to be processed by the electrical system, which complicates the pump system. , and many water pumps for field work drive power, but the use of external travel switches or proximity switches requires signal conversion through the electrical system, which makes the water pump system complicated, and many water pumps are used for field work and cannot provide drive for the electrical system power supply

Abstract

The invention discloses an automatic reversing water pump. The automatic reversing water pump comprises a water pump body and a hydraulic drive system, wherein the hydraulic drive system communicates with the water pump body, and a signal valve is arranged between the hydraulic drive system and the water pump body. According to the automatic reversing water pump disclosed by the invention, a speed reduction device and unnecessary drive mechanisms and signal feedback mechanisms are not arranged, and thus a light weight is achieved; an output flow can be completely adjusted as needed; a power direction is the same as an action direction of the water pump, and thus low power consumption and high efficiency are achieved; the piston-type water pump is high in anti-pollution capacity and capable of easily adapting to poor water quality; straight reciprocating motion is adopted, a piston of the water pump is free from an eccentric load, and the service life is prolonged; and acquisition manners for a hydraulic signal are various at the tail end of a stroke of an oil cylinder, and are simple to realize.

Description

technical field [0001] The invention relates to a water pump, in particular to an automatic reversing water pump. [0002] technical background [0003] A technical implementation route of the current traditional water pump is: using the principle of the crank slider or piston mechanism, the rotation of the crank is converted into the reciprocating linear motion of the slider or piston, in order to meet the appropriate flow requirements and adapt to the movement speed of the piston Requirements, it is often necessary to add a deceleration device between the power and the crank. The existing deceleration device is generally a reduction box, and the weight is relatively large. Another type of plunger water pump is to convert the crank rotation into the reciprocating motion of three plungers. This type of water pump plunger allows a faster reciprocating speed, but has poor anti-pollution ability and is not suitable for water quality containing impurities and particles. . In t...
