Product Introduction
Developed in accordance with GB/T 25974 - 2010 Hydraulic Supports for Coal Mines (Part 2: Technical Specifications for Columns and Jacks; Part 3: Control Systems and Valves), a national standard, this test bench is mainly used for the factory tests and loading tests of columns and jacks of hydraulic supports. It can also conduct factory performance tests on various valves for hydraulic supports, such as safety valves, pilot - operated check valves, stop valves, directional valves, and high - pressure hoses.
The test bench meets the inspection requirements of the latest national standards. It adopts sensors for data collection and digital instruments for display, and supports two operation modes: computer operation and electrical button operation. The display accuracy reaches 0.01 MPa. It has many characteristics, including safety and reliability, high testing accuracy, and ease of use.
