Yishan DLGF electric two-stage PM VSD mining screw compressors — Shaanxi Yishan Compressor — Xianyang

Datasheet

Product overview

Power: 110 / 280 kW motor — examples · Pressure: 0.8 MPa — two table examples · Flow: 23 / 50 m³/min — basis to confirm

Yishan's DLGF mining series is an electric, two-stage permanent-magnet variable-speed screw compressor family. It is not a diesel portable compressor. The official table lists DLGF23/8-110B at 23 m³/min, 0.8 MPa and 110 kW motor power, and DLGF50/8-280B at 50 m³/min, 0.8 MPa and 280 kW. Both rows specify two-stage compression, direct drive and 1480 r/min. The flow reference and gauge/absolute pressure basis need confirmation; the listed motor rating is not measured total electrical package input.

The literature describes PM drive, variable-frequency PLC control, two-stage compression and filtration. Its KA discussion concerns non-coal underground and metal/non-metal mining equipment. A small certificate collage is not enough to verify the current certificate numbers, validity or exact ordered model coverage. Obtain current approval documents matched to the machine and intended site, and the destination mine's acceptance requirements. A KA logo, mobile arrangement or general tunnel use does not establish coal-mine explosion-proof suitability.

For a mine air-supply enquiry, identify the mine type and installation location, environment and hazardous-area classification, electrical supply/protection, required use-point pressure and simultaneous tool airflow, cooling and ventilation, altitude, access/transport and condensate/oil handling. Establish the actual selected motor/controller, controls and shutdowns, receiver/piping scope, maintenance clearances, commissioning and inspection records. Energy-saving claims need an agreed load profile and measured package performance rather than a generic percentage.
