The pneumatic hydraulic pump is to convert the relatively low air pressure into high pressure oil, that is, to use the low pressure at the piston end of a large area to produce a small area of high hydraulic pressure. It can replace the traditional manual or electric hydraulic pump with the anchor cable tension equipment, anchor withdrawal device and anchor rod tension meter and other hydraulic tools. So, how is the working principle of the pneumatic hydraulic pump? Here is a simple analysis for you.
First, the pneumatic hydraulic pump can flush water, oil or other types of chemical media. The gas driving pressure of the pneumatic hydraulic pump should be controlled in the range of 1-10bar, its working principle is similar to the reciprocating cycle of the supercharger, its bottom piston has two four-way valves to control.
Second, the pneumatic hydraulic pump is a type of automatic filling, under normal circumstances, it is not necessary to use the air line lubricator. When the piston is driven upward, the liquid will be sucked into the pneumatic hydraulic pump, at this time, the valve at the entrance will be opened, and the valve at the exit will be closed. When the piston moves down, the liquid in the pump will create a certain pressure on one side, and the resulting pressure will close the valve at the entrance and open the valve at the exit.
Third, the pneumatic hydraulic pump can achieve automatic circulation, when the pressure at the outlet increases, the pneumatic hydraulic pump will slow down, and produce a certain resistance to the differential piston, when the two forces balance, the pneumatic hydraulic pump will automatically stop running. When the pressure at the outlet decreases or the driving pressure of the gas increases, the pneumatic hydraulic pump will begin to operate automatically.
Fourth, when the pneumatic hydraulic pump is used, it is safe and reliable, the pressure output energy rate is large enough, the operation is also very simple, and it is widely used in heavy industry fields such as metallurgy, mining, shipbuilding, etc., and has good explosion-proof effect in coal mine production.
Fifth, the pneumatic hydraulic pump can be in a certain pre-booked pressure, will not consume energy, will not produce heat, do not produce heat will not occur sparks and flames, greatly reducing the probability of safety hazards in production; The pressure of the pneumatic hydraulic pump can reach 7000 pa, which can meet the requirements of most high-pressure operations.
