JSF-S-5.6-Ex Explosion proof BT4 Pipeline Axial Flow Fan

Overview of HTF Axial Flow Fire Exhaust Fan Products

The HTF series axial flow fire exhaust fan is a product of the "Spark" project, which has excellent performance, good high temperature resistance, occupies less space than centrifugal fans, and is easy to install.

2. Excellent high temperature resistance: The fan test meets the requirements of the GBJ45-82 fire protection standard, and an enterprise internal control assurance system higher than this standard is established. It can operate continuously for more than 30 minutes under high temperature conditions of 280 ℃

Continuous operation for more than 20 hours/time at a temperature of 100 ℃, widely used in high-end civil buildings, ovens, underground garages, tunnels and other occasions.

3. Wide applicability: Depending on the different requirements of high-end civil buildings, variable speed or multi speed drive can be used to achieve the purpose of dual-use (i.e. ventilation during normal times and high-temperature smoke exhaust during firefighting). If the user

When high noise requirements are required, it can be made into a silencing fan.

4. Easy to install and occupies less space than centrifugal fans: The basic form of this fan is an axial flow fan, which can be directly connected to the air duct or installed on the wall. The installation form can be vertical or horizontal. Greatly saving floor space.

JSF-S-5.6-Ex Explosion proof BT4 Pipeline Axial Flow FanUse, maintenance, and upkeep

1. Before installation, carefully check whether the fan blades and casing are damaged or deformed due to transportation, otherwise they should be repaired before installation;

2. Check if the connecting bolts are loose. Before starting the fan, first check if there are any obstacles to rotation in the fan duct;

3. Check whether the insulation performance of the motor is good, and after connecting the power, check for friction, collision, and abnormal vibration;

There are many reasons for fan vibration, which can be checked from the following aspects:

a. The impeller rubs against the air duct and produces abnormal sounds and vibrations;

b. The bracket foot bolts are not tightened, which can also cause significant vibration;

c. The connecting bolts between the impeller and the shaft sleeve are loose;

d. Loose bolts connecting the bracket to the motor cause imbalance of the impeller and damage to the bearings, resulting in intense vibration.

If the motor temperature rises too high when running at room temperature, it may be caused by the following reasons:

a. The motor bearing is damaged and the fit clearance is small, which does not meet the requirements;

b. The installation of the shaft and bearings is skewed, and the two bearings have different axial degrees;

c. Low power supply voltage or three-phase motor running in phase failure;
