Working principle and troubleshooting of hydraulic system of disc heat disperser
(l) Working principle of hydraulic system of disc heat disperser
The hydraulic transmission system of disc heat disperser is shown in Figure v. The hydraulic system is supplied by the hydraulic pump, the pump inlet is equipped with an oil filter, and the outlet is connected with the hydraulic system. The working oil passes through the precision filter 5. The solenoid directional valve 7 supplies oil to the feed hydraulic cylinder 10 and the body maintenance hydraulic cylinder 11. The operator controls the action of electromagnetic directional valve 7 through the circuit on the control panel, and then controls the hydraulic cylinder to drag the moving grinding plate for axial displacement to change the grinding plate clearance, so as to realize the accurate positioning control of the moving grinding plate.
(2) Fault analysis and elimination of hydraulic system
g. The oil return port of cooler is blocked.
⑤ There are several reasons for system noise and noise.
