Problems solved by technology

[0003] (2) The existing control method of the engine for the mobile pipeline pump unit--PID adjustment, as shown in Figure 1, that is, when the parameter is greater than or less than the set value, enter the proportional + integral + differential (PI) adjustment; the existing problem is in The fixed value is easy to cause frequent adjustments. The closed delivery mode of the pipeline "pump-pump" makes the whole line a unified hydraulic system. Frequent adjustments of the pump unit will easily lead to system oscillation and instability, which will eventually lead to paralysis of oil transportation.
However, because the fuzzy control only takes a limited control level, the improvement of precision is limited, and there is a static error

Embodiment Construction

[0147] The control method of the engine used in the mobile pipeline pump unit of the present invention is as follows: the automatic protection control of the pump unit is mainly used, and the automatic adjustment of the oil delivery working condition is supplemented; SSB protection adjustment is supplemented;

[0148] The automatic protection control of the pump unit is mainly based on the automatic adjustment of the oil delivery working condition, which means that when the working condition parameters of the unit exceed the safe working limit, the automatic control device of the pump station unconditionally enters the protection control, namely: alarm, reduce idle speed, and take off the pump , or even an emergency stop; when the parameters of the working condition of the unit are normal, it enters the adjustment of the oil delivery condition, and the adjustment adopts the double-position fixed-value band adjustment of the inlet pressure, and the single-side belt protection ad...

Abstract

This invention relates to one mobile tube pump set motor control method, which uses pump set automatic protection control as main part and output work automatic adjusting as aid for inlet pressure double level band adjusting for main part and exit pressure single band protection adjusting as aid, wherein, the set work parameters is over safety work limit for entering alarm, reducing speed and removing from pump to rapid protection control ; when the work is in safety status, entering inlet pressure double position band adjusting method, exit pressure single band protection adjust as aid automatically adjust output work.

Description

field of invention [0001] The invention relates to a method for controlling and adjusting the engine of a mobile pipeline pump unit in a "pump-pump" sealed delivery mode. Background technique [0002] (1) Existing control technology for fixed pipelines - SCADA system, centralized monitoring of the entire line. Centralized control of the entire line is inseparable from communication, and communication in wartime is one of the main targets of the enemy. Therefore, the mobile oil pipeline system must be based on the local control of the pump unit. [0003] (2) The existing control method of the engine for the mobile pipeline pump unit--PID adjustment, as shown in Figure 1, that is, when the parameter is greater than or less than the set value, enter the proportional + integral + differential (PI) adjustment; the existing problem is in The fixed value is easy to cause frequent adjustments. The closed delivery mode of the pipeline "pump-pump" makes the whole line a unified hydra...
