Hydraulic power unit (HPU) as oil installations

Hydraulic power unit (HPU) as oil installations , it is through external piping system is connected with a number of hydraulic cylinders to control multiple valve action . Tanks, pumps and accumulators to form an independent power oil closed source system . Petrol stations can be equipped with PLC control system , which controls all internal hydraulic functions and generate signals and the control room (DCS) exchange . Control components such as hydraulic servo valve mounted directly on the hydraulic cylinder , through the valve into the high-pressure hydraulic cylinders, or from which the release of high pressure oil. In the normal state , pump oil to the system to automatically maintain system rated pressure , through the control valve atresia, to achieve the valve in any position to secure his position under the function ; in working condition , hydraulic actuator controlled by the solenoid valve , the system command signal the solenoid valve action, control pressure and the accumulator energy release , and then control slide valve cylinder , valve driven by mechanical transmission mechanism , the implementation of rapid closure of the normal opening and closing , and test control . hose fittings Pressure cylinder can be fixed on the stem can also be used directly as the executing agency . Returns excess hydraulic oil hydraulic oil stations, such piping systems with an inlet pipe a return pipe can control several parallel connection of the valve. This has a special hydraulic drive technology is used to control the main steam turbine bypass valve and actuator system action .
Changsha QIANRUN power unit technology-related technology products
Power unit is designed for all applications optimized design, for example, can be used in harsh environments trucks running or heavy hauler condition for a long time , and other products that require high performance and high quality of the occasion . We will also anticipate greater application flexibility and more cost requirements. Thereby to produce an extremely diverse universal platform , using standard components, able to respond to market demand for most application conditions , the hydraulic components of the customer inventory levels to a minimum , china hydraulic hose but also greatly reduce the workload of the non-standard design . Power unit also makes special reference to cost advantage . For example HE power unit , built on a multi- universal platform, allowing the use of motor sizes from 80 to 132mm (0.3 ~ 4.5kw), the pump displacement from 0.24 to 5.7cc. A power unit can control up to four cylinders . The core component is the adapter . There are two different specifications. With a variety of shapes and installation.
