The difference between the automatic pressure filter and the ordinary filter press is that the automatic drawing board system, the automatic liquid turning plate, the automatic cleaning filter and so on are many. Make the operation of the equipment more intelligent and automated. The structural design of the whole machine is scientific and reasonable, the mechanical strength is high, the structure is stable, the durability is durable and it is easy to operate and maintain.
The automatic pressure filter detects the oil pressure of the current pull plate hydraulic system through the pressure transmitter, and transforms the perceived pressure signal into the analog quantity recognized by PLC, so as to control the advance and retreat of the pull plate. The photoelectric switch can make the pull plate system achieve immediate pause / recovery in the drawing process or the whole system operation process, so that the operation process is more humane.
Automatic filter press hydraulic system for the vertical structure, two basic movements can automatic compacting pressure and loosen cylinder complete hydraulic system, improves the safety and reliability of the whole hydraulic system, maintenance and convenient for users, the key elements of the whole hydraulic station: joint venture Wuxi hydraulic components factory by German oil cylinder products, a one-way valve, reversing valve, relief valve and other hydraulic components of the Taiwan and Shanghai Huadao hydraulic parts factory products, so that the entire hydraulic system more safe and reliable, to ensure that users of the whole filtering process completed successfully.
The hydraulic system is composed of three parts: power system, control system and executive element. The control system is composed of high pressure relief valve, pressure gauge, one-way valve, electromagnetic reversing valve, hydraulic check valve, low pressure relief valve, electric contact pressure gauge and so on. Cylinder compression pressure by the pressure relief valve setting pressure, pull plate by low pressure relief valve set pressure maintaining system, the one-way valve and the valve control, the realization of the two basic movements through the electromagnetic valve oil cylinder clamping loosen; electric contact pressure gauge cylinder cavity (high pressure chamber) auto fill pressure, the pressure stable in a range, to ensure the smooth completion of the filtration process.
The hydraulic system of the oil motor pull plate and take off plate is composed of three parts: the power system (low flow plunger pump 10r/min), the control system (hydraulic component) and the executive element (oil motor). The control system is composed of the low pressure relief valve and the electromagnetic reversing valve. The pressure of the oil motor pulling plate is adjusted by the relief valve (3-4Mpa), and the pull plate speed is kept within a suitable range. The two basic actions of the oil motor pull plate and plate removal are achieved through the electromagnetic reversing valve.
