Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] In order to realize the reliability loading and unloading solenoid valve and ensure the working reliability of the pumping station, this embodiment relates to a control method for the loading and unloading solenoid valve of the pumping station. For details, see figure 1 A description is made as follows.

[0029] S1: Determine whether the maximum two pressure sensors used to detect the pressure on the main pipeline are overpressured, if so, enable the overpressure fault flag, unload the solenoid valve and return to S1, if not, proceed to S2.

[0030] The pump liquid output by the pump station will enter the main pipeline through the solenoid valve, and a pump head pressure sensor will be installed near the solenoid valve to detect the pressur...

Abstract

The invention discloses a control method for loading and unloading solenoid valves in pumping stations, including: S1: judging whether at most two pressure sensors are overpressured, if yes, enabling the overpressure fault flag, unloading the solenoid valves and returning to S1, if not, performing Go to S2; S2: judge whether to receive the overvoltage fault reset signal, if so, clear the overvoltage fault flag and proceed to S3, if not, proceed to S3; S3: read the overvoltage fault flag, judge according to the overvoltage fault flag Whether the pumping station has a system overpressure failure, if so, unload the solenoid valve and return to S1, if not, proceed to S4; S4: judge whether the valve control enable signal is enabled, if not, unload the solenoid valve and return to S1, if so, automatically control Solenoid valve and proceed to S5. The invention is used to solve the problem of single control and low reliability of the loading and unloading electromagnetic valve of the pump station in the prior art.

Description

technical field [0001] The invention relates to the technical field of mine control, in particular to a control method for a loading and unloading electromagnetic valve of a pump station. Background technique [0002] The pump station used in coal mines provides hydraulic pressure, and provides support and moving power for the fully mechanized mining face through hydraulic supports, etc. The output pump fluid (such as emulsion) of the pump station enters the main pipeline through the solenoid valve and provides pressurization power for the equipment on the fully mechanized mining face. When the solenoid valve is loaded, the pump fluid enters the main pipeline through the solenoid valve, and the When unloaded, the pump fluid returns to the liquid tank and does not provide pressurization power for the equipment on the fully mechanized mining face. Therefore, the solenoid valve is a key component of the hydraulic control of the pumping station. [0003] At present, the tradit...
