Abstract A horizontal spiral discharge filtering centrifuge is a solid-liquid separation equipment which is to use the principle of filtering to separate suspension。 It is widely used in chemical, food, chemical fiber, metallurgy, pharmaceutical, light industry and other industries for suspension and solid-liquid separation and dehydration。 Hydraulic system is an important part of the centrifuge。 The hydraulic system of the horizontal spiral unloading filtering centrifugal machine includes (1) drum hydraulic system, (2) spiral hydraulic system, (3) the hydraulic cooling system and (4) hydraulic tank。 The main content of this research is to improve the performance of the hydraulic system of the horizontal screw discharging and filtering centrifuge。 Optimize the transformation on the basis of the original hydraulic system。
This paper introduces the working principle and the function of each component of the horizontal screw centrifuge。 The theoretical method of reforming hydraulic system is analyzed。 Then optimize the hydraulic system of the filter, and attache the optimized hydraulic principle diagram。Then use a software called AMESim to simulate hydraulic system before and after optimization。 Compare and analyze the performance of the components before and after optimization, including the flow and speed of the drum motor and screw motor and the displacement of plunger cylinder。 The simulation results show that, when the load is changed, the variable pump's response is more sensitive after optimization。 The efficiency of the whole hydraulic system is also improved。 The optimized hydraulic system is reasonable in design, compact in structure and strict in structure。
