压滤机是将砂浆中的水分挤压过滤的设备,其工艺过程包括以下步骤(如图1)。原用Z80单板机对其工艺过程进行自动控制,由于该单板机没有采用有效的抗干扰和提高可靠性的措施,使该设备在运行过程中故障率高,可靠性差,因此该设备在我公司没能得到有效使用。可编程序控制器(PLC)工作 Filter press is the water squeezed mortar filter equipment, the process includes the following steps (Figure 1). The original Z80 single-board machine for its process of automatic control, the board as the machine does not use effective anti-jamming and improve the reliability of the measures to make the device in the operation of the high failure rate, poor reliability, so the device in the My company did not get effective use.
