- Product Introduction
Product Introduction
Pneumatic Gear Pump Type Anchor Cable Tensioning is suitable for prestressed anchoring projects such as mines, tunnels, and bridges. It is characterized by large tensioning force, reliable operation, good sealing performance, long service life, simple operation, and convenient maintenance. This product has the advantages of high efficiency, compact structure, small size, light weight, stable operation, and small pressure fluctuation. It is an ideal equipment for anchor cable installation and testing in the coal mining industry.
Working Principle
The mining anchor cable tensioning machine is powered by a pneumatic oil pump, which is transmitted through pipelines and the jack is used as an actuator to tension the anchor cable. The pneumatic gear oil pump works with compressed air as the power, controls the gear motor through the intake valve, and drives the first-stage gear oil pump and the oil suction valve to work. The high-pressure power hydraulic oil is output through the reversing valve to enter the actuator tensioning jack. The high-pressure oil acts on the outer cylinder and the core shaft. The claw locks the anchor cable while the jack presses the anchor to achieve the anchor cable pre-tightening operation.
Performance Characteristics
- HISCORE independently designs and develops pneumatic gear hydraulic pump station
- The efficiency of pneumatic gear hydraulic pump station is increased by more than 3 times
- Can deliver oil in both directions and operate with dual oil circuits
- More reliable and durable
- Mining product safety standard certification
- The whole series uses top-grade bearings
- Direct sales from the manufacturer, worry-free
Specifications
Example:
MQ22-300/60 means: a mining anchor cable tensioning machine with a rated tension force of 300kN and a jack rated pressure of 60MPa.
