Hydraulic unit in use can choose water, oil or other working medium, belongs to a complete unit of work, demand connection components. Hydraulic units are used to drive the bolt stretcher, remove the interference fit of shaft parts, wheel, Marine stern rudder and so on. According to the different work requirements, the unit can choose pneumatic hydraulic pump as the core, or in electric hydraulic pump as the core.
The former operation more safe and reliable, the pressure of up to 7000 bar; While the latter is the pressure of up to 5000 bar; With manual hydraulic pump as the core pressure of up to 2800 bar hydraulic unit. Need to compressed air driven pressure pump. Compressed air pump connected to the existing pipeline system can, do not need to connect the power supply can be stressful.
In practice, a hydraulic unit need to configure the corresponding components, mainly including the air control unit, including combined filter and water separator, pressure regulating valve, pressure gauge and manual shutoff valve. In practical applications, the mobile and portable hydraulic unit can be used for any need to hydraulic pressure. Widely used in steel construction, boiler manufacturing, construction of the tank and the reactor engineering, as well as in refinery, smelting factory, fitter plant and machinery.
Hydraulic unit can be driven hydraulic punching machine and punching system, thus can be used for the plane's lifting, large equipment fixture device, pressure vessel and pressure piping systems. In hydraulic tool, it can also be used in hydraulic connection and installation and removal of large gear equipment. In addition, can also be used to need long time pressure maintaining equipment such as hydraulic fixture, such as tyre vulcanizing machine and fixture overload protection.
In order to achieve such a request, in the hydraulic system, power unit can provide one side or both sides enter the clamp circuit device. Compressed air directly back to connect a fast loop. Therefore, the hydraulic unit has a wider range of application in practice, and can effectively improve the efficiency.
