Electro-hydraulic valve is composed of a main valve and two solenoid valves. The main valve response speed control device consists of two small ball valves installed between each solenoid valve and the corresponding inlet or outlet valve. These controls (small ball valves) are adjusted to control the flow into and out of the medium above the diaphragm so that the opening/closing speed of the main valve can be adjusted based on the viscosity and pressure of the medium used. According to the statistics of the team members, most failures of the electro-hydraulic valve are caused by the inlet or outlet solenoid valve not charged.
(4) Bad communication cable contact, loose power supply insurance
In the analysis meeting of the team, the engineer proposed that there were two problems with the touch screen. First, after the system started, the PT touch screen could not control or input or output, and the field was displayed as The reason was that there was a problem in the communication between the touch screen and PLC, and the cable was not in good contact. Secondly, after the system started, the PT touch screen was not bright. After on-site processing and analysis by Lu Yan, the 24VDC power supply of the touch screen was not supplied, and the power supply insurance was loose.
