The hydraulic pump station of small goods lift is the power source of the hydraulic system. It provides certain pressure, flow and clean working medium to the system, and is an important part of the hydraulic system. The hydraulic pump station is suitable for various hydraulic machinery that can be separated from the hydraulic device, such as freight elevators, scissor lifts, etc.
There are three types of hydraulic pump stations according to the arrangement of their pump sets: top type, cabinet type and non-top type. Among them, the upper type includes vertical type and horizontal type. The non-top-mounted type includes integral type and separate type. The top-mounted hydraulic pump station with the pump group arranged above the oil tank is called a vertical hydraulic pump station when the motor is installed vertically and the hydraulic pump is placed in the oil tank. The hydraulic system of the freight elevator uses this kind of pump station as the power source. It has the characteristics of compact structure, small footprint, and is widely used in small and medium power hydraulic systems.
The hydraulic pump station of the freight elevator is usually composed of the following five relatively independent units, which are the pump set, the fuel tank component, the temperature control component, the accumulator component, and the filter component, which can be selected according to different requirements in practical applications. .
The pump set of the lifting platform is composed of hydraulic pump, prime mover, coupling, transmission base, pipeline accessories, etc.
The freight elevator fuel tank is used to store enough oil required by the system, dissipate the heat generated by the system, and separate the gas precipitation pollutants in the oil.
The temperature control component of the freight elevator consists of two components: heating and cooling. When the heat balance of the hydraulic system cannot keep the working medium within a suitable temperature range, a temperature control component should be installed in the hydraulic system of the freight elevator lift to keep the medium temperature at a reasonable temperature. within the control range.
The accumulator assembly is usually composed of accumulator, control device, support stand and other components.
The function of the filter assembly of the hydraulic lifting platform is to separate insoluble solid particles from the liquid, prevent the friction of the particle pollutants on the hydraulic components and block the small cross-section flow passage, and prevent the deterioration of the oil itself.
