Dongyue · Jinan Compressor Factory

Jinan Compressor Factory Co., Ltd. (济南压缩机厂有限公司) dates its manufacturing history to 1974. Its current range separates mine equipment, industrial two-stage screw and mobile air supply, with receivers, air treatment, vacuum and station-control routes.

Company material describes design/production responsibility and key-parts provision. The national standards platform also names the company among drafting participants for plan 20250138-T-604, a revision concerning general-purpose oil-injected single-screw compressors. This participation is distinct from an individual product certificate or the architecture of every machine.

Match the working environment first

Mine screw, coal-mine protection and chemical protection are separate routes

DLGF · metal/non-metal mines

The DLGF12/8-75 page describes this application and belongs to the supplier's KA-labelled catalogue route. Select the actual mine duty and required qualification documents.

MLGF · coal-mine mobile route

The manufacturer groups mobile explosion-protected MLGF equipment under its separate MA-labelled route. Do not substitute a DLGF name for that complete model and application.

Gas/dust · chemical route

The chemical explosion-protected range is listed separately again. The operating environment, exact equipment marking and applicable model documents belong in the review.

The catalogue describes PM variable-speed motor/control and two-stage compression. Those terms do not establish a universal savings percentage for a new installation.

Confirm the current delivery conditions and engine make/model, declared rating, emissions and ambient/altitude derating for the destination. The smaller LGFY-10/8-C reference's 75 kW power must not be assigned to this model.

Specify air pressure at the tool after hose losses, simultaneous demand, transport/lifting and service access. Wheels or a tow arrangement alone do not establish road approval or underground/hazardous-area suitability.

Station configuration

Published project records include mine stations with 6000 V/10000 V configurations and air/water-cooled equipment, alongside construction applications. Review electrical and cooling scope for the selected installation.

Define receiver, dryer, filters, downstream losses, station controls and the pressure/air quality needed at the user. A catalogue's 380 V unit and a high-voltage station are separate offered configurations.

Inspection and ongoing support

The company describes maintenance/parts provision and rotor repair or exchange. Obtain current parts/overhaul scope, model/serial traceability, factory test procedures and installation/commissioning terms.

For remote monitoring, specify included functions, network and permissions, alarm response and offline protection. Agree the responsible support provider and destination service arrangements.

Dongyue procurement questions

Is DLGF the same as the coal-mine MLGF route?

The current supplier catalogue separates them. DLGF12/8-75 describes metal/non-metal mining; MLGF mobile explosion-protected coal-mine equipment has a different route. Match the exact offered model and required environment documents.

Can I compare two-stage machines using motor power alone?

Use delivery and complete-package input at the same pressure/reference conditions, with the actual demand profile and usable control range. Motor kW and broad savings headlines do not establish installed-system energy use.

Can the LGFY-10/8-C power be used for LGFY-26/21-C?

They are separate models. Obtain the actual engine make/model, declared rating and site derating for LGFY-26/21-C, together with its current delivery record.

What does drafting participation prove?

The standards platform records company participation in a revision plan. It is separate from an individual product performance test, safety approval or the architecture of every compressor.

Specification pages

All spec pages
DutyWrite on the RFQ
22 kW VSD screw compressor 22 kW VSD is a flow band, not a single nameplate FAD. The plant needs min/max flow at the working pressure, or it will quote a fixed-speed machine with an inverter sticker.
Compressor for mining Site air at altitude is not a 7 bar catalogue FAD. Diesel vs electric, hose length and ambient change the machine.
13 bar rotary screw compressor 13 bar(g) is a laser and textile pressure, not a general 8 bar plant. Write FAD at 13 bar and the kW the site can feed.
50 Hz 380 V screw compressor Chinese plants build 50 Hz 380 V packages every day. They cannot retag a 60 Hz 460 V nameplate in the quotation without a motor change. Write the supply first.
