Pneumatic hydraulic pumps are widely used in metallurgy, mining, marine machinery, petrochemical and other fields. Particularly suitable for coal mine explosion proof requirements of the occasion. Pneumatic hydraulic pump will be lower air pressure into high-pressure oil, QYB-55-type pneumatic hydraulic pump is a double oil structure, with a manual valve, hydraulic valve can be achieved through the manual into the commutation. Instead of manual or electric hydraulic pumps and anchor tensioning equipment, anchoring machines, bolt tension meter or other hydraulic tools supporting the use of significantly reduce labor intensity, improve efficiency and become the ideal power source. Pneumatic hydraulic pump safe, reliable, high output pressure, easy to operate, easy to carry and so on.
