What components do hydraulic power units components includeHPU Hydraulic power units are a hydraulic system with hydraulic actuators hydraulic cylinders, hydraulic motors connected to the control valve operation to achieve the operation of the equipment for the adopted oil pressure apparatus. Hydraulic power units come complete with a power section electric motor, hydraulic pump, the control section pressure valves, directional control valves, flow control valves, and the auxiliary section couplings, manifold block, suction pipe, return pipe, tank, air breather, etc. First, the Power Section     1 Motor hydraulic power unit power source. The motor hydraulic power units main role is to convert electrical energy into mechanical energy. Generating a driving torque, hydraulic power units function as a power source. Hydraulic power units are commonly classified according to the power supply of the motor, and can be divided into DC motors and AC motors. Where in the AC motor and the DC motor include 2 poles and 4 poles. Electric motor common parameters. Rated power is the motors maximum working power recommended operating conditions. POWER RATING is motor power. Rated voltage or operating voltage. Since the motor can generally operate at different voltages, the voltage is directly related to the speed, and other parameters have to change accordingly, so that the voltage is only a suggestion. No load speed. The unit is RPM, meaning revolutions per minute. Since there is no load speed reverse torque, the output power and the stall situation is different, the effect parameters only provide maximum speed of the motor at a predetermined voltage. Stall torque is an important parameter to take a lot of the load of the motor. That is, when the motor is reversed by an external force to stop the rotation torque. If the motor stall phenomenon occurs often, it will damage the motor, or burned driver chips, so when you choose the motor, which, in addition to speed, is the first parameter to be considered. Usually the relationship values and the operating voltage is not very close. Note that, however, stalled over time, the motor temperature rises rapidly, the motors value will decline rapidly. No load current is closely related to current and torque. There is certainly no load current, because voltage and energy formed is divided into potential energy and heat energy consumption. Heat is related to the motor coil, the better the motor, at no load, the smaller the value. Buddhadeb Basu Books more. Starting current. This parameter is also important. For a good motor, under the same acceleration, the starting current will be small. Hydraulic pump the heart of the hydraulic power unit. Hydraulic pump means a hydraulic power unit capable of converting mechanical energy into hydraulic pressure. Driven by the motor, providing flow and pressure of the hydraulic actuator action desired. Thus, it can be said that the hydraulic pump is the heart. There are several types of hydraulic pumps gear pumps, vane pumps, and piston pumps. Gear pumps. Compact hydraulic power units normally work with hydraulic gear pumps. At present, the industrys leading manufacturer in Italy is Marzocchi pumps High Pressure Gear Pump Company. Gear pump advantages are simple structure, easy fabrication, low cost, small size, light weight, self priming performance, not sensitive to pollution of the oil, reliable, and high speed range. How Hydraulic gear pump work. As shown capstan clockwise, then seal the suction chamber at T, because the tooth is disengaged children volume increases, the formation of a vacuum, atmospheric pressure hydraulic oil tank into the suction chamber T, the room filled with alveolar, this is the pump suction process with the rotation of the gear, with oil constantly being brought into pressure oil chamber P, teeth into engagement on that side, the volume decreases, forcing oil output, this is the process of pumping oil. And syringe injection medicine procedure is very similar. Gear pumps common parameters. Pressure rating refers to the maximum under the premise volumetric efficiency of the pump, and the life of the rated speed, continuous operation of the pump allows the use of pressure to ensure that more than this value is overloaded. Rated pressure and maximum working pressure of the pump pressure is not actually at work. Displacement refers to the pump shaft rotation, excluded volume of oil. Here we must distinguish between displacement and rated flow. Rated flow at rated pressure and speed conditions, the output of a predetermined flow rate. Speed dependent, but no relationship between displacement and speed. Efficiency, broken down into mechanical efficiency and volumetric efficiency, showed losses in torque and pump flow. Second, the control section As with the development of the hydraulic power unit cartridge valve in the increased range, a wide range of hydraulic power units are also increasing. The main production base for the current international cartridge valves in the United States include Hydraforce Hydraulics Cartridge Valves, Sun Hydraulics, Eaton vickers Eaton, Parker Hannifin Parker, and Fluid Control. Sterling Hydraulics and Integrated Hydraulics are companies in the UK. In Germany there are Bosch Rexroth, HYDAC, and Fluid Team. Wandfluh, and Bucher Frutigen are from Switzerland. In Italy there are Comatrol and Oil Control. In Sweden, and Denmark Sauer Danfoss. Keta Hydraulics and Haihong Hydraulics are from China. And Target Hydraulics company from Ningbo Hydraulics. Pressure control valves Pressure control valves on the hydraulic power units with pressure relief valve, sequence valve, relief valve, are pressure relay based. Almost each hydraulic power unit comes complete with a relief valve. Sequence valves, relief valves, and pressure switches on some special hydraulic power units have a sequence of actions, and the same system has different working pressures used, such as dock leveler hydraulic power units for logistics equipment and paper cutter production line hydraulic power units. Relief Valve umbrella of hydraulic power unit Pressure relief valves on the hydraulic power unit have primarily a security role, they limit the maximum pressure to avoid other hydraulic components, and pipe damage.
