Embodiment

[0043] Such as figure 1 , image 3 As shown, a control method for automatically starting and shutting down a water delivery pump set includes the following steps:

[0044] 1. The sub-method for starting the water pump control;

[0045] 2. The sub-method for shutting down the water delivery pump.

[0046] Said step 1 water delivery pump startup control sub-method includes the following steps:

[0047] Step 101, PLC1 detects the status information of the water delivery pump 2, and judges whether the condition for turning on the pump is satisfied, if yes, execute step 102, if no, execute step 112;

[0048] Step 102, PLC1 waits for the command to turn on the pump, and judges in real time whether the command to turn on the pump is received, if yes, execute step 103, if not, return to step 101;

[0049] Step 103, PLC1 controls to open the vacuum forming device 4;

[0050] Step 104, judge whether the vacuum is formed, if yes, execute step 106, if no, execute step 105;

[0051] ...

Description

technical field [0001] The invention relates to a water pump control method, in particular to a one-step control method for automatic startup and shutdown of a water delivery pump group. Background technique [0002] The outlet pump of the water plant is an important equipment produced by the water plant. The outlet pump unit of the water plant is composed of a water pump, an electric valve, and a vacuum system. The start and stop of the outlet pump unit are completed by a series of action combinations. Usually, the sequence action of the outlet pump group is observed by the operator, and the whole process is completed one by one. This method is neither convenient nor reliable, and is often prone to misuse. Contents of the invention [0003] The purpose of the present invention is to provide a one-step control method for automatically starting and shutting down the water pump group with high reliability, simplified and standardized water pump operation steps, and the syst...
