9 days of continuous fighting，Days ago，Hanjiawan Coal Company 2-2Coal glue transport alley transportation system、Two sets of frequency converters for the main belt inclined shaft transportation system are officially put into operation，marks the successful completion of the company’s main transportation system frequency conversion transformation project，Creating favorable conditions for achieving a “good start” in the first quarter。
"The main transportation system is changed from CST drive to inverter drive，will be used in practice、Maintenance、Shows many advantages in management and other M88 appaspects。" said Zhao Li, the head of the Mechanical and Electrical Materials Management Center who participated in the entire project transformation。
The frequency converter can realize stepless speed regulation，The transportation speed can be adjusted according to the coal transportation volume，Reduce equipment wear，Reduce operating costs；The low-speed operation of the inverter is stable，It satisfies the tape inspection very well、Maintenance、Maintenance work；The variable frequency drive tape machine is very convenient during the equipment debugging stage，If there is deviation in the initial stage，Can adjust deviation at a slow speed；From frequency converter、Parking is convenient，Can well meet the operation of the tape machine、Maintenance work；High frequency converter control accuracy，Can control speed and torque accurately and quickly；The frequency converter can reduce the impact of large current on the power grid at the moment of starting of high-voltage and high-power motors；Inverter parking includes free parking and variable frequency parking，Soft parking in the true sense，And feed excess energy back to the grid；The inverter M88 loginrequires less maintenance，Increased running time。
Frequency conversion transformation through the main transportation system，Not only realizes remote centralized control of the main coal flow，Effectively improves equipment operating efficiency，Greatly meets the needs of safe production，And greatly reduces equipment maintenance、Repair costs，The direct and indirect economic benefits are very significant。
It is reported，This renovation project makes full use of the mine shutdown for maintenance during the Spring Festival，People participating in the project She Xiaojia、For everyone，Voluntarily give up going home for the New Year，Work overtime、Working day and night at the construction site，And overcome many difficulties，Finally, the project was successfully completed according to the estimated construction period，Another “weight” for the company to build a new sample of high-end first-class intelligent mines of the same scale with all coal。（Li Huigang）
