Abstract

The invention discloses a hydraulic drive system for a crusher and the crusher applying the hydraulic drive system. The hydraulic drive system comprises an oil tank, a hydraulic main pump and main motors, wherein an oil supplementing opening of the hydraulic main pump communicates with the oil tank; and an oil outlet of the hydraulic main pump communicates with oil inlets of the main motors, and an oil inlet of the hydraulic main pump communicates with oil return ports of the main motors, so that a closed oil way is formed between the hydraulic main pump and the main motors, and the main motors can be connected to external crushing shafts. In this way, hydraulic oil is circulated, so that the closed oil way is formed between the hydraulic main pump and the main motors. The oil return portsof the main motors directly discharge the hydraulic oil back to the oil inlet of the hydraulic main pump without passing through the oil tank, so that a closed system is formed to benefit the improvement of the sealing performance of the oil way, the air infiltration or impurity mixing is avoided while the stability of the oil way at work is improved, and the overall system is more energy-savingand efficient.

Description

technical field [0001] The invention relates to the field of crushers, in particular to a hydraulic drive system of a crusher and a crusher using the same. Background technique [0002] With the development of biomass power generation technology, biomass power generation has the advantages of environmental protection and cleanness due to the use of renewable fuels, so it is gradually popularized. Biomass power generation needs to crush biomass materials, so the demand for the development of crushers is becoming stronger and stronger. [0003] Since the processed materials put into the crusher include a variety of substances, the physical properties such as hardness and toughness are different among the substances, and even mixed with hard substances such as iron blocks, the load of the drive system fluctuates greatly, and it is easy to be overloaded. In the working state, if the motor or engine is directly driven, it is easy to cause damage to the drive system. Therefore, ...
