Hybrid transmission slurry pump gearbox system and control method thereof

Abstract

The invention provides a hybrid transmission slurry pump gearbox system and a control method thereof.The system comprises a control unit, a motor operation unit, a clutch transmission unit, a slurry pump working unit and a diesel engine power unit, and the motor operation unit, the clutch transmission unit, the slurry pump working unit and the diesel engine power unit are in control connection with the control unit; instruction information sent by the upper computer is received, operation information of the motor operation unit, the clutch transmission unit, the slurry pump working unit and the diesel engine power unit is returned, and the motor operation unit, the clutch transmission unit, the slurry pump working unit and the diesel engine power unit are connected through gear meshing. After the diesel engine power unit operates, the clutch transmission unit controls the slurry pump working unit to work, and meanwhile the motor operation unit provides electric energy or stores electric energy according to the operation conditions of the slurry pump working unit and the diesel engine power unit. The output power of the system can be flexibly adjusted, and energy consumption in the operation process of the slurry pump is reduced.

Description

technical field [0001] The invention relates to the technical field of application of dredging mud pumps, in particular to a gear box system of a mixed transmission mud pump and a control method thereof. Background technique [0002] Dredgers include cutter suction dredgers, trailing suction dredgers, etc. They are responsible for clearing silt in waterways and rivers so that other ships can pass smoothly. The task of the dredger is to carry out the construction of underwater earthwork, specifically: dig deep, widen and clear existing waterways and ports; excavate new waterways, ports and canals; dredging docks, docks, locks and other waterways. The foundation trenches of construction and buildings, and the excavated sediments are thrown into the deep sea or filled in land depressions to create fields, etc. [0003] Because there are mud sand, silt, stones and even wood and other debris under the water, the working conditions of the mud pump of the dredger are very differen...

AI Technical Summary

Problems solved by technology

[0003] Since there are sundries such as mud, silt, stones and even wood under the water, the working conditions of the mud pump of the dredger vary greatly, and the vibration of the mud pump is relatively large during operation, so the matching diesel engine must be 15% larger than the rated power of the mud pump. to cover, so the waste of diesel engine power is relatively large, that is, 15% of the power is wasted
