Wuxi Van filter works Hebei Van filter works Yuzhou Charming Chemical Machinery Co., Ltd. Van filter press works hydraulic filter press filter press hydraulic press mechanism composition of hydraulic stations, fuel tanks the structure and composition of the piston, the piston rod connected to the piston rod pressing plate havran card hydraulic station motor, oil pump, relief valve (the adjustment pressure) valve, pressure gauge, fuel lines, tanks. Hydraulic compression mechanical compression when hydraulic station for the high-pressure oil cylinder and piston constitute component cavity full of fluid when the pressure is greater than the frictional resistance of the compression plate running, the slow compression plate to compress the filter plate, when pressing force of the pressure relief valve setting value (displayed by the gauge pointer), filter plates, filter box (plate and frame) or filter plate (van) is pressed, the relief valve start unloading, which when the cut off electrical power, the clamping action is completed, returned, reversing valve, pressure oil into the cylinder rod chamber when the hydraulic overcome the frictional resistance of the pressing plate, clamping plate withdrawal begins. Hydraulic compression for automatic packing, pressing force is controlled by the electric contact pressure gauge, maximum pressure gauge pointer and the lower limit of the pointer is set at the value of the process requirements, limit when the pressing force of the pressure gauge on the power cut off, oil pump to stop power supply, due to the pressing force may arise within the hydraulic system leakage and leakage caused decline, down to a pressure gauge lower limit pointer, the power is turned on, the oil pump to start oil pressure reaches the upper limit, the power cut off , oil pump to stop oil supply to reach the filter material in the process, so that the cycle to ensure that the effect of the clamping force. Filtering way: the filtrate outflow distinct flow filter and undercurrent filter. Each filter plate below the liquid hole filled with water Tsui Ming-flow filtration, the filtrate outflow from the water Tsui intuitive. Undercurrent filtered, each filter plate is provided below a liquid passage hole, the liquid out of the several blocks Plates Kong Liancheng a liquid passage out liquid from the bottom of the thrust plate hole is connected to the discharge pipe. Washing method: cake need to be washed, sometimes flow check washing and bi-washing undercurrent of one-way the washed and bi-washing. The flow unidirectional washing, turn into lotion lotion into the hole from the thrust plate through the filter cloth and then through the filter cake, never well filter plate outflow, then the orifice plate out of liquid water Tsui is off, The orifice plate out liquid water Tsui is turned on. Flow bidirectional washing lotion twice washing lotion into the hole from the thrust plate on both sides of the party that the lotion to start again from the other side of the wash wash, lotion exports with imports diagonal direction, so called two-way cross-washing. The undercurrent unidirectional flow Polyester lotion in order from the lotion into the hole of the thrust plate into the orifice, through the filter cloth and then through the filter cake, from no outflow of well filter plate. Undercurrent bi-washing lotion twice washed two lotion into the hole from the stop board on both sides of the party, and that the washing first side of the wash, and then the other side washing lotion export the diagonal direction, so called undercurrent two-way cross-washing.
