Abstract

The invention provides a high-pressure plunger pump interlock protection control method and system based on PID adjustment. The control method comprises an inlet pressure control method, a pump head vibration control method, a filler water leakage control method, a crankcase oil temperature control method and an outlet pressure control method. The control system comprises an interlock protection controller, a frequency converter, an outlet pressure transmitter, an inlet pressure transmitter and an inlet flow transmitter, wherein the frequency converter, the outlet pressure transmitter, the inlet pressure transmitter and the inlet flow transmitter are connected with the interlock protection controller. The outlet pressure transmitter is installed on an outlet pipeline and connected with a pressure adjuster. The pressure adjuster is connected with the frequency converter. The high-pressure plunger pump interlock protection control method and system based on PID adjustment adopt an automatic control system, the safety class of the control system is high, the effect that the control system operates safely, reliably and stably can be ensured, the program logic is designed precisely, the safety interlock protection function is perfect, and the whole process of water flooding production is covered.

Description

technical field [0001] The invention belongs to the technical field of high-pressure plunger pump equipment, and in particular relates to a high-pressure plunger pump interlock protection control method and system based on PID adjustment. Background technique [0002] Most of the plunger pumps used in the production process of the oil field are manually controlled, and there are few safety protections. There are potential safety hazards during the operation of the pump, which will cause the water in the oil tank of the equipment to emulsify and the crankshaft to burn. The inlet flow rate is low, resulting in safety accidents such as dry piston and damage to the piston. Therefore, each detection point is used to alarm the temperature, pressure, flow, water volume and vibration and interlock the parking. Contents of the invention [0003] In view of this, the present invention aims to propose a high-pressure plunger pump interlock protection control method and system based ...
