Pump truck power matching control method and system

Abstract

The invention discloses a pump truck power matching control method. The method includes the steps that current pump truck working condition environment parameters are detected; a database is inquired for obtaining pump truck optimal power parameters matched with the current pump truck working condition environment parameters; and according to the pump truck optimal power parameters, the working state of an engine and the working state of an oil pump are adjusted. By the adoption of the method, a full-working-condition pumping test can be conducted on a pump truck in a plateau region in advance, plateau demarcation of the engine is finished, and corresponding parameters are recorded to establish the database. In the actual operation process, the current pump truck working condition environment parameters including the altitude height, the gear and the oil way pressure are detected firstly, then the database is inquired for obtaining the matched pump truck optimal power parameters according to the current pump truck working condition environment parameters, and then the working states including the engine rotation speed and the engine power coefficient of the engine and the oil pump control current of the oil pump are adjusted to guarantee that the pump truck has the high work efficiency when the engine works stably. The invention further discloses a pump truck power matching control system. The beneficial effects of the pump truck power matching control system are mentioned above.

Description

technical field [0001] The invention relates to the technical fields of vehicle engineering and automatic control, in particular to a power matching control method for pump trucks. The invention also relates to a pump truck power matching control system. Background technique [0002] With the development of China's machinery industry, the automobile industry has made great progress. [0003] There are many types of cars, such as engineering vehicles and special vehicles, and pump trucks are a common engineering vehicle. In the plateau area, due to the thin air and low air pressure in the plateau area, it has a great influence on the power and torque of the engine of the pump truck. At the same time, because the current pump truck does not have measures and methods to adjust the power of the pumping system for high altitude areas, if the power of the pumping system on the top is not adjusted, it is very likely that the engine will fail due to insufficient engine power durin...

Problems solved by technology

At the same time, because the current pump truck does not have measures and methods to adjust the power of the pumping system for high altitude areas, if the power of the pumping system on the top is not adjusted, it is very likely that the engine will fail due to insufficient engine power during the construction of the pump truck. Rapid or even flameout

[0004] In the prior art, the power of the oil pump is often reduced by further limiting the opening of the oil pump to prevent the engine from stalling. However, this control method blindly reduces the power of the oil pump without making adjustments according to the actual situation of the engine of the pump truck. It cannot fundamentally solve the problem of insufficient engine power and black smoke due to low atmospheric pressure and insufficient fuel combustion. The method of power usage has greatly reduced the working efficiency of the pump truck, and the gain outweighs the gain
