A turbocharger is essentially a hydraulic amplifier. In a hydraulic system, if the entire system requires low pressure and a local or specific branch requires high pressure, a turbocharger can be used to provide high-pressure oil to the local oil circuit or a certain actuator of the system, which is several times higher than the working pressure of the hydraulic pump, to meet the needs of the local working mechanism. There is no need to separately set up expensive high-pressure oil pumps, and the system still operates at a lower pressure. This can reduce energy consumption, reduce equipment, and simplify the system.
      Commonly used superchargers are generally divided into single acting and double acting types. Single acting superchargers can only intermittently output high-pressure oil, while double acting superchargers can continuously output high-pressure oil. Their common characteristics are composed of a low-pressure cylinder, a high-pressure cylinder, large and small pistons, an electromagnetic reversing valve, and a signaling device for controlling the electromagnetic reversing valve; The large piston end inputs low-pressure oil, while the small piston end outputs high-pressure oil. The direction change of the turbocharger is achieved through frequent switching of the electromagnetic directional valve. Frequent switching of the solenoid valve can cause overheating of the solenoid coil over long working hours, which not only affects the performance of the valve, but also leads to an increase in oil temperature. In severe cases, the machine needs to be shut down to cool down. In addition, a separate circuit needs to be set up for the turbocharger even when it is far away from the power source.
How to simplify the system and explore new ways of reversing the turbocharger has always been a new topic of concern for people.
Composition of hydraulic control double acting supercharger
      The hydraulic control double acting supercharger is a self reversing double acting supercharger that eliminates the traditional supercharger's electromagnetic directional valve and the signaling device that controls the electromagnetic directional valve. It uses a plug-in valve as the main directional valve and a small flow two position four-way hydraulic directional valve as the pilot valve. There are two small holes on the cylinder body of the low-pressure cylinder, and the position relationship between the large piston and the small holes is used to change the position of the pilot valve to control the action of the main valve and achieve the direction change of the supercharger.
        The form of the high-pressure cylinder piston (piston type or plunger type) and sealing method, as well as the type of sealing components, the diameter and number of pull rods, and the reinforcement sleeve of the high-pressure cylinder, all need to be determined according to the output pressure and boost ratio of the turbocharger.
The purpose and characteristics of hydraulic dual acting supercharger;       Hydraulic dual acting boosters are widely used in brakes, clutches, high-pressure test benches, high-pressure jets, high-pressure cutting, oil well water injection boosting, as well as in equipment such as engineering metallurgy and mining.
        The hydraulic control double acting supercharger simplifies the system and expands its range of use by eliminating the electromagnetic directional valve. It adopts a plug-in valve, which makes the structure simple, stable and reliable, reduces processing costs, and increases flow rate. Therefore, this type of supercharger can be used as a high-pressure pump. Using compressed air as a power source to obtain high pressure oil makes it easy to achieve gas-liquid conversion.
