[0002] During the working process of the crusher, if it always uses the same stable crushing speed or acceleration for crushing, when encountering various complicated crushed materials, it will easily rotate forward-reverse-rotate forward and repeat the work repeatedly, resulting in actual production The efficiency is low. In order to improve the adaptability of complex crushed materials, different crushing speeds and acceleration crushing controls are carried out for materials with different stable working pressures, which can greatly improve the actual operating efficiency of the crusher.

The invention discloses an optimization control method for improving the crushing efficiency of a hydraulic crusher. The hydraulic crusher comprises a control unit, an engine and an oil pump driven bythe engine. The oil pump is connected with motors through a hydraulic pipeline. Motor drive shafts are connected with a speed changing box drive shaft. The speed changing box drive shaft is connectedwith and drives tool box tool shafts to rotate. The engine is connected with the control unit and controlled by the control unit. According to the method, linkage control is mainly conducted on the crushing speed and the work pressure actually needed for the crushed materials, when the crushing pressure is in different load pressures, different crushing speed (oil pump displacement control) control modes are selected, the material crushing and pulling acceleration is increased, the crushing pressure overpressure is reduced, the reverse rotation frequency is reduced, the material crushing adaptability is improved, and the work efficiency is improved.
Description
technical field [0001] The invention relates to an optimization control method, in particular to an optimization control method for improving the crushing efficiency of a hydraulic crusher. Background technique [0002] During the working process of the crusher, if it always uses the same stable crushing speed or acceleration for crushing, when encountering various complicated crushed materials, it will easily rotate forward-reverse-rotate forward and repeat the work repeatedly, resulting in actual production The efficiency is low. In order to improve the adaptability of complex crushed materials, different crushing speeds and acceleration crushing controls are carried out for materials with different stable working pressures, which can greatly improve the actual operating efficiency of the crusher. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides an optimal control method for improving the crushing e...
