Abstract

Embodiments of the present invention provide an excavator control method, device and excavator, and relate to the field of engineering control. The method includes obtaining the temperature of the hydraulic oil of the excavator and the oil return pressure of the breaker; when the temperature is greater than a preset temperature value, increasing the control current of the cooling pump; , reduce the control current of the main pump. Increasing the control current of the cooling pump can increase the output power of the cooling pump and improve the cooling efficiency of the hydraulic oil, thereby rapidly reducing the temperature of the hydraulic oil, thus ensuring the normal operation of the breaker and avoiding the decrease in the efficiency of the hydraulic system of the excavator. Reducing the control current of the main pump can reduce the output power of the main pump and the oil inlet flow of the breaker, thereby reducing the oil return pressure of the breaker, thus avoiding damage to the filter element of the breaker due to excessive oil return pressure and prolonging the excavator. The service life of the breaker.

Description

technical field [0001] The invention relates to the field of engineering control, in particular to an excavator control method, device and excavator. Background technique [0002] In the process of engineering construction, excavators equipped with breaker hammers are used more and more frequently, and large breaker hammers are more efficient and economically beneficial. Therefore, developers and construction personnel are more inclined to use large breaker hammers for operations . [0003] At present, due to the large power of the large breaker, the efficiency of the hydraulic system of the excavator may be reduced when the large breaker is used, which will lead to a decrease in the strike frequency of the large breaker, and even damage the breaker, which is not conducive to the development and construction personnel's high efficiency. Operation. Contents of the invention [0004] The purpose of the present invention includes, for example, providing an excavator control...
