Abstract
The invention discloses a method for controlling a marine pump and relates to the technical field of electrical control equipment manufacturing. The implement method comprises the following steps that 1 a first pump serves as a working pump, a second pump serves as a standby pump, and a manual/automatic toggle switch is shifted to the automatic transmission; 2 if the pressure of the outlet of a pipeline is too low, a pressure relay makes a signal circuit to transmit a signal, and after being delayed by a third time relay, a first relay controls the circuit action; 3 the first relay makes the first pump control electric action of the circuit automatically, and a first pump automatic control circuit controls the first pump to start for entering a working state; 4 if the first pump is broken down, after being delayed by a second time relay, the second pump controls the electric action of the circuit automatically, and a second pump automatic control circuit controls the second pump to start for entering the workings state; 5 when a machine needs to be stopped, the manual/automatic toggle switch is shifted to the zero transmission, and the water pump stops working. By means of the method, the problem that the service life of the pump is shortened due to the fact that the pump is shifted frequently can be solved.
