DEFINITION:

Air hydraulic pump will be lower air pressure into high-pressure oil, that is, the use of a large area of low-pressure piston end to produce a small area of high-hydraulic piston end. The utility model can replace manual or electric hydraulic pump and be matched with anchor cable tensioning tools, anchor releasing machines, anchor rod tension meters or other hydraulic tools.

air hydraulic pumps

How it works:

1

Air hydraulic pump can flush water, oil or filled with chemical media. The gas driving pressure ranges from 1 to 10 bar. It works like a reciprocating supercharger. The bottom piston is controlled by a two-way four-way pilot valve.

2

Pneumatic hydraulic pump for self-filling pump, in general, without the use of air line lubricants. When the drive piston runs upward, the liquid will be sucked into the pump, at this time the one-way valve at the entrance to open, the one-way valve to close the export. When the piston runs down, the liquid side will form a certain pressure, the pressure will be the entrance of the one-way valve closed, the one-way valve opened at the exit.

3

Air hydraulic pump can achieve automatic circulation. When the outlet pressure increases, the pneumatic hydraulic pump will slow down, and the differential piston has a certain resistance, when the force balance, air hydraulic pump automatically stop running. When the outlet pressure decreases or the gas-driven pressure increases, the air hydraulic pump will automatically start operation.

Features:

Air hydraulic pump with safety valve oil filler

safe and reliable, high output pressure, easy to operate, easy to carry and so on.

Purpose:

Air hydraulic pump is widely used in metallurgy, mining, shipping, machinery, petrochemical and other fields. The utility model is especially suitable for the occasions with explosion-proof requirements in coal mines.

Purpose:

can be maintained at any preset pressure, no more energy consumption and heat generation

no heat generation, no spark and flame hazards;

pressure linear output, easy manual control;

up to 7000 PA supercharging capacity, meet most high pressure requirements;

easy to use in automatic control systems;

continuous start and stop, no restrictions, no adverse effects;

pneumatic piston rings and other pneumatic components in working state without the need to add lubricating oil, the utility model can save the running cost, prevent the environment from being polluted by oil and gas, and is portable,

reliable, easy to maintain and durable.

use Compressed air as power source, do not need to use power supply,

running oil-free lubrication
