step B2: extracting a horizontal basic value S0, a horizontal deviation range value Sf and a water flow speed deviation active value L0, generating an amplitude image according to a time image of a first amplitude value Z1 and a second amplitude value Z2, acquiring an amplitude period T1 and a deviation maximum value D1 of the first amplitude value Z1, and acquiring an amplitude period T2 and a deviation maximum value D2 of the second amplitude value Z2;
step B3: judging whether the pump body (11) is in a normal operation state in the operation process of the pump, wherein the specific mode is that when the absolute value of S-S0 is less than or equal to Sf, the operation of the pump belongs to a normal state, and when the absolute value of S-S0 is more than Sf, the operation of the pump belongs to an abnormal state I;
judging whether the efficiency of the pump is in a normal operation state or not in the operation process of the pump, wherein the specific mode is that when | Lc | < L0, the efficiency of the pump belongs to a normal state, and when | Lc | > L0, the efficiency of the pump belongs to an abnormal state II;
judging whether the vibration on two sides of the pump body (11) is in a resonance state or not in the operation process of the pump, specifically, when T1 is equal to T2, and the time point of the first amplitude value Z1 deviating from the maximum value D1 and the time point of the second amplitude value Z2 deviating from the maximum value D2 in the same period are coincident, the pump body (11) is in a third abnormal operation state.
9. The industrial pump with the safety protection mechanism as claimed in claim 6, wherein the processing module is used for acquiring abnormal states in the judgment result of the processing module and processing and prompting the maintainers, and the specific steps are as follows: when the abnormal state I and the abnormal state II are obtained, informing a worker to carry out maintenance and inspection treatment; and when the abnormal state III is acquired, the operation of the pump body (11) is immediately stopped, and then a worker is informed to carry out maintenance and inspection processing.
