Abstract

The invention relates to the technical field of control, and discloses a start-stop control method and system for a jacking oil pump and an overflow electromagnetic valve. The method comprises the following steps that the instruction type of a start-stop instruction is judged when the start-stop instruction is received; when it is judged that the instruction type is a start instruction, a first delay signal is generated, and a logic and a module are triggered to generate a first pulse signal; the overflow electromagnetic valve is controlled to be powered off after being powered on for a firstpreset duration according to the first pulse signal, and the jacking oil pump is controlled to be started in a delayed mode according to the first delay signal; when it is judged that the instructiontype is a stop instruction, a second delay signal is generated, and a logic and a module are triggered to generate a second pulse signal; the overflow electromagnetic valve is controlled to be poweredoff after being powered on for a second preset duration according to the second pulse signal, and the jacking oil pump is controlled to be stopped in a delayed mode according to the second delay signal so as to ensure that the jacking oil pump and the overflow electromagnetic valve are in a no-load state during start and stop, so that the pressure value in the jacking oil pump is reduced to a safety level, and adverse effects on the system caused by sudden oil pressure rise are prevented.

Description

technical field [0001] The invention relates to the field of control technology, in particular to a start-stop control method and system for a jacking oil pump and an overflow solenoid valve. Background technique [0002] With the development of the jacking oil pump control technology, only controlling the start and stop of the jacking oil pump can no longer meet the production needs. In industrial production, the stability of the jacking oil pump is even more required. The sudden increase of the oil pump pressure has a great impact on the system. The impact caused is immeasurable, and the economic loss caused is also something that no enterprise wants to bear. The overflow solenoid valve is of great help to the stability of the start and stop of the oil pump. Therefore, the jacking shaft oil pump can be started and stopped by combining the overflow solenoid valve. It is in a no-load state when it stops, so that the pressure value in the jacking shaft oil pump drops to a saf...
