Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] Such as figure 1 As shown, a bolt chain control method of a high-pressure water gun pumping station is characterized in that it comprises the following steps:

[0021] A. A one-way valve 4 is set on the water supply pipeline 3 connecting the high-pressure water gun 1 and the high-pressure water pump 2, and a pressure switch 5 is respectively set on both sides of the one-way valve 4, and the output ends of the two pressure switches 5 are connected to the controller 6, The output relay of the controller 6 is connected to the high-pressure water pump 2, and sets different pressure setting values ​​for the two pressure switches 5;

[0022] B. Set the control logic of the controller 6 as follows: when the two pressure switches 5 detect no pressure signal at the same time, that is, when the logic value is 0, the logic value of the o...

Abstract

The invention belongs to the technical field of washing device control and relates to a high pressure water gun pump station gunlock interlocking control method. The method includes the following steps that A. a one-way valve is arranged on a water supply pipeline connected with a high pressure water gun and a high pressure water pump, a pressure switch is arranged on each side of the one-way valve, the output ends of the two pressure switches are connected with a controller, and an output relay of the controller is connected with the high pressure water pump; B. the control logic of the controller is arranged to be that when the two pressure switches detect a non-pressure signal simultaneously, namely the logic value is 0, the logic value of the output relay of the controller is 1, and the high pressure water pump is operated; when any of the two pressure switches has state change, namely the logic value is from 0 to 1 or from 1 to 0, the logic value of the controller changes from 1 to 0, the controller outputs a stopping signal to the high pressure water pump in a delaying mode, and the high pressure water pump can stop in a delaying mode. The high pressure water gun controls the high pressure water pump and achieves the effects of saving energy and being safe and wide in adaptability.

Description

technical field [0001] The invention belongs to the technical field of cleaning equipment control, and relates to a gun lock chain control method of a high-pressure water gun pumping station. Background technique [0002] In real life, the configuration of high-pressure water guns used for car washing or cleaning equipment is: high-pressure water pumps, water pipes, and water guns. That is, the water pump and the water gun are directly connected, and the water gun can only function after the water pump is turned on. In actual use, people need to turn on the water pump first, and then go to the position to be cleaned for operation. After cleaning, they need to go back to turn off the water pump, which is very inconvenient. In addition, there is also a problem of safety. When people's operations cause the water gun to drop due to an accident, the water gun is turned off, and the water pump cannot be shut down in time, which may cause danger. Therefore, the mode of controllin...
