Hydraulic assembly for mining system

A hydraulic assembly (10) for a mining system (100) comprises at least one control valve (2) for controlling a supply of hydraulic fluid to a hydraulic actuator (9, 11) of the mining system. At least one temperature sensor (12) is associated with the at least one control valve (2) and detects a temp...

Beschreibung
Zusammenfassung:	A hydraulic assembly (10) for a mining system (100) comprises at least one control valve (2) for controlling a supply of hydraulic fluid to a hydraulic actuator (9, 11) of the mining system. At least one temperature sensor (12) is associated with the at least one control valve (2) and detects a temperature of the at least one control valve (2). A control unit (6) receives the temperature measured by the at least one temperature sensor (12) and an ambient temperature, and determines that a leakage has occurred in at least one control valve (2) when a temperature difference exceeds a predetermined threshold. 种用于开采系统(100)的液压组件(10)包括用于控制液压流体向开采系统的液压致动器(9、11)的供应的至少个控制阀(2)。至少个温度传感器(12)与所述至少个控制阀(2)相关联，并且探测所述至少个控制阀(2)的温度。控制单元(6)接收环境温度和由所述至少个温度传感器(12)测量的温度，并且在温差超过预定的阈值时，判定在至少个控制阀(2)中已经发生渗漏。
