MECHANICAL COAL MINER'S HYDRAULIC SYSTEM

摘要

1. The hydraulic assembly of a coal shearer is equipped with hydraulic engines, located in two driving units, and connected to the main pump. Unique characteristics: The main pump (1) is connected, through the feed direction separator (2) and the pipes (3) and (4) to the sliding separators (5) and (9). The latter are connected to the hydraulic engines (8) and (12) with the pipes (6), (7), (10) and (11). The sliding separators (5) and (9) are controlled through the electro-hydraulic separators (14) and (15) by the pressure produced by the auxiliary pump (13).
