Mining the normal operating procedures of the fan:
(A), to launch the operation:
A. Accurate closed and open throttle, axial mine fan shall be open throttle launch, should be leading to the underground into the throttle open ground into the throttle open, and to support solid, to prevent the suction surface wind take the initiative to pull open.
Two. Centrifugal mine fan shall be open throttle launch is about to throttle and ground leading to the underground into the throttle of all open.
3. Initiative adopted by magnetic station, half take the initiative to launch the device, should be envisaged in manual operation.
4. , The electrical effect of the slip ring wound rotor induction electric effect of the adoption of the rheostat to manually launch hand in the launch position, the resistance of all access, launch control handle in the \"stop\" position. DC at the end of fall to be launched gradually toggle handle slowly removal of resistance, as well as removal of all, Turning short circuit, electric effect into deformity speed running form.
5 Squirrel-cage asynchronous electric effect of th e adoption of internal resistance to launch, launched before the electrical effect of the rotor should be access to all internal resistance. After launch, to be launched DC back to the outdated, manually (or active) excision of all the internal resistance of the electrical effect into the malformation run.
6. Synchronous effect of asynchronous launch excitation pulling into synchronization, it is premature. Impedance compound muffler excitation transferred to the extreme, the current pressure, DC, to meet the used excitation device task straight line. Synchronous electric effect agreed to successively launch twice. For stagnation launched three after the two can not be launched before the survey must be required to reason and condition of the facilities before deciding whether to launch.
(B), the launch of the mine fan damper operation:
A. Axial mine fan: Open the damper leading to the underground, at the same time opening up the ground into
Throttle.
Two. Centrifugal mine fan: Open the damper leading to the underground.
(C), it is important mine fan abnormal shutdown operation:
A. Receipt of the competent subordinates down notice.
Two. Drying downtime.
3. Stop notice, decided to spare mine whether to open the line of fans, For the CDB backup fan, according to the above-mentioned malformations operation application stagnation.
4. Not open backup fan should be open to the wellhead explosion-proof door and damper, to make full use of artificial ventilation.
(D), the main mine exhaust fan fan stagnant class tour review:
A. Tour to review the work is generally once per hour.
Two. Circuit review of an important form of:
(1) each rotary position should be no abnormal noise and abnormal shock;
(2) bearing measure may not be overrun;
(3) electrical effect of temperature rise does not go beyond the provisions to apply;
(4) measuring instructions deformity;
(5) The generator DC, not to exceed the additional value prohibited ultra-laden line;
(6) The voltage should be consistent with the generator malformations run the application, should not lecture the mine in charge of skilled personnel, to determine whether to continue running.
3. Attention to the review of negative pressure changes at any time, to find strange circumstances shall promptly report to the nominal Ministry.
(4) the problems found in the tour review and engaged by the running diary must be promptly filled.
(E), it is important mine fan driver routine forms of protection:
An axis lubrication:
(1) sliding bearings should be required to apply for current oil to fuel the daily operation, from time to time to maintain the required oil level;
(2) mobile bearing oil lubrication, fuel compliant ahu units;
(3) to curb the contrary oil confusing to use.
2 spare mine fans mu st always keep a complete form:
(1) 1 to 3 months stagnation time replace the run, the longest not to exceed six months;
(2) replacement to exceed one month standby mine use the fan should have a monthly stagnation empty run once, at least one previous hour, in order to protect the spare mine fan deformity complete, enter the run within 10 seconds.
