Overview

I. Main Uses and Applicable Scope

The FQ series mine pneumatic axial flow local ventilation fan (hereinafter referred to as the fan) is a widely used new product with features such as compact structure, small size, light weight, simple operation, easy maintenance, and good safety performance. The blades and corresponding housings of the fan have undergone friction spark safety performance testing and can be used in environments with flammable gases such as methane and oil gas.

Main uses of mine pneumatic extraction axial flow local ventilation fan: Local ventilation extraction in coal mines; Scope of use: Workplaces required in coal mines with the risk of methane gas explosion.

Main uses of mine pneumatic pressure axial flow local ventilation fan and mine pneumatic counter-rotating axial flow local ventilation fan: Pressure local ventilation in coal mines; Scope of use: Workplaces required in coal mines with the risk of methane gas explosion.

II. Normal Applicable Environment

(1) Altitude not exceeding 2000m;

(2) Relative humidity of ambient air not exceeding 95%RH (+25℃);

(3) Ambient air temperature: +4℃～+40℃;

Structural Features

The FFQ series mine pneumatic axial flow (counter-rotating) local ventilation fan consists of a housing, pneumatic motor (primary and secondary), impeller (primary and secondary), filter, and protective ring. The fan structure is shown in the figure:

Working Principle

High-pressure air is supplied from the lower air pipe. After connecting with the fan intake with a hose and opening the valve, the high-pressure air drives the pneumatic motor to rotate, driving the impeller to rotate. The impeller works on the air, giving the air energy and discharging it from the fan at a certain speed, guided by the air duct or discharged directly.

The company's main business is the design, research and development, and manufacturing of various ventilators and their supporting products for mines, non-coal mines, and rail transit. Products involve 38 series of fan products, more than 3,000 specifications, including FB(D) series, FBC(D)Z series, FKZ series, rail transit SDS series, tunnel SDF series, etc.; supporting products include shaft, inclined shaft self-resetting explosion-proof doors, louver-type automatic regulating air doors, side-opening (vertical) automatic regulating air doors, butterfly valves, silencers, main ventilator online detection and fault diagnosis systems, non-stop fan reverse systems and intelligent oil injection systems, which can fully meet the ventilation needs of mines and are sold to various domestic fields and international markets such as Russia and Canada.

In recent years, the company has successively won the honorary titles of "Yuncheng Enterprise Technology Center", "Yuncheng Excellent Enterprise", "Yuncheng Intellectual Property Demonstration Enterprise", and "Innovative Small and Medium-sized Enterprise".
