Title:

AUTOMATIC SUPPLYING PRESSURE COMPENSATION SYSTEM AND CONTROL METHOD THEREOF

Document Type and Number:

WIPO Patent Application WO/2016/082356

Kind Code:

A1

Abstract:

Disclosed is an automatic supplying pressure compensation system, comprising a switch control device (1), an oil supply device (2), a pressure compensation device (3) capable of real-time detection of the variation of inner cavity pressure thereof, and a power unit (4) associated with the pressure compensation device (3), the pressure compensation device (3) supplying oil to the power unit (4). The switch control device (1) refers to the detection result of the pressure compensation device (3), and if the inner cavity pressure is smaller than the pre-set first threshold value, the oil supply device (2) is triggered to supply oil to the pressure compensation device (3); if the inner cavity pressure is larger than the pre-set first threshold value, the oil supply device (2) is triggered to stop supplying oil to the pressure compensation device (3). The automatic supplying pressure compensation system is able to detect in real time the inner cavity pressure of the pressure compensation device (3) and automatically supply oil, and thus can effectively provide pressure compensation to the power unit (4).
