Medium-thickness coal seam series coal mining machine

Product Advantages and Features:

Highly reliable hydraulic system

1. Duplex pump. The large displacement pump is used for height adjustment system and the small displacement pump is used for brake system to reduce the system power loss.

2. The oil return pipeline is installed with fin-type cooler to guarantee that the oil temperature is below 50. 

System level based gear micro-modification technology

The gears are micro-modified based on the housing deformation condition to prevent the partial offset load of tooth face.

 High-reliability electric system

1. The harness design within electric cabinet realizes the stratified layout for cables and fluid pipes within the machine body.

2. The high integrated and modularized design is taken for the main control cabinet and inspection cabinet to ensure integral replacement and easy maintenances.

3. Shock test and inspection for electric components.

 High machining accuracy of housing

1. The housing is finish machined by imported machining center to guarantee perfect dimensional tolerances and roughness for the housing and thus ensure the good functioning of whole drive system.

2. The imported constant-temperature coordinates inspection center is used to inspect the housing and guarantee 100% tolerance conformance.

 Advanced electric control system

1. The black box data storage system can record all data during the running of coal mining machine, with failure memory and inquiry function.

2. The complete intelligent self-diagnostic system provides the failure locating and warning functions. 

Multi-sensor shock test analytic technology

The shocks of all shafts in engagement direction are effectively controlled to improve the drive stability. 

Modularity

The medium-thickness coal seam series coal mining machine features high modularity and interchangeable main components and parts so that the mine owner can change the performance of coal mining machine at a really low cost to adapt to diversified mining needs. 

Quadrant control by highly reliable frequency converter

By simulating the site working conditions, we made a lot of tests and analysis to finally obtain the quadrant electric control strategy of frequency converter suitable for high inclination working conditions.
