Basic Conditions Of Hydraulic Pump

Hydraulic machine principle: the use of hydraulic oil to pass the pressure of the equipment. Hydraulic oil in the closed container is the pressure to follow the Pascal law hydraulic press system by the power mechanism, control agencies, implementing agencies, auxiliary agencies and working medium components. Power mechanism is usually used as a power pump, usually for the displacement pump. In order to meet the requirements of the speed of the implementing agencies, use a pump or a number of pumps. Low pressure (oil pressure less than 2.5MP) with a pump; medium pressure (oil pressure less than 6.3MP) with a high pressure pump (oil pressure less than 32.0MP) with a piston pump.Hydraulic Pump

The hydraulic pump is the power source of the hydraulic system. Constitute the basic conditions of the hydraulic pump is: a variable sealed volume, coordinated oil distribution mechanism, and high and low pressure chamber isolated structure. The main performance parameters of the hydraulic pump and the hydraulic motor are: displacement, flow, pressure, power and efficiency; the displacement is the geometric parameter, and the flow is the product of the displacement and the speed; the actual working pressure depends on the external load; the hydraulic power is Pump output flow and working pressure of the product; volumetric efficiency and mechanical efficiency, respectively, reflects the hydraulic pump and motor volume loss and mechanical losses. Hydraulic pump and hydraulic motor according to the different forms of structure, mainly divided into gear type, blade type, plunger type three categories, to master all kinds of pumps, motor working principle, displacement and flow calculation method to understand its structural characteristics The Hydraulic Pump

Hydraulic presses usually refer to hydraulic pumps and hydraulic motors, hydraulic and hydraulic motors are energy conversion devices in the hydraulic system, the difference is that the hydraulic pump to drive the mechanical energy of the motor into the oil pressure energy, hydraulic system is the power plant, and Hydraulic motor is the oil pressure can be converted into mechanical energy, hydraulic system is the implementation of the device. Hydraulic system commonly used in hydraulic pumps and motor hydraulic press are volumetric, and its working principle is the use of sealed volume changes in oil and oil pressure.Hydraulic Pump
