Embodiment Construction
[0020] refer to figure 1 As shown, the operation method of double-pump operation of coal mill thin oil station to prevent skipping grinding includes the following steps:
[0021] 1) DCS gas station start command 1;
[0022] 2) The oil pump in the control cabinet selects the first oil pump to work, and the second oil pump is standby 2;
[0023] 3) The first oil pump contactor excitation 3, DCS oil pump operation feedback 4;
[0024] 4) The first oil pump runs 5;
[0025] 5) The oil pressure of the system is abnormal 6;
[0026] 6) The second oil pump of the hydraulic joint starts to run 7;
[0027] 7) DCS double pump operation alarm 8, switch the forced start switch 9;
[0028] 8) Eliminate the fault 11, the system oil pressure is normal 10, and the forced switch is released 12;
[0029] 9) The system is running normally13.
[0030] In the step 2) the control cabinet can also control the second oil pump to work, and the first oil pump is in standby 14 .
