Product Description

9-19 9-26 series centrifugal blower fan Application

9-19 and 9-26 centrifugal fans are generally used for forging furnaces and high-pressure forced ventilation, and can be widely used for conveying materials, conveying air, and gases that are non-corrosive, non-spontaneous, and non-viscous. The temperature of the medium generally does not exceed 50°C (maximum 80°C). The dust and hard particles contained in the medium do not exceed N150mg/m3.

Type

This ventilator is of single suction type. There are NO.4, 4.5, 5, 5.6, 6.3, 7.1, 8, 9, 10, 11.2.

Structure

No.4-6.3 is mainly composed of impeller, casing, air inlet, bracket, etc.; No.7.1-16 is mainly composed of impeller, casing, air inlet, transmission group, etc.

① Impeller 9-19 type fan has 12 blades, 9-26 type fan has 16 blades. All belong to the forward curved leaf type. The maximum peripheral speed of the outer edge of the impeller diffuser does not exceed 140m/s. After the impeller is formed, the static and dynamic balance are corrected, so it runs smoothly.

②The casing is welded with ordinary steel plate to form the whole volute casing.

③The air inlet is made into a convergent streamlined overall structure, which is fixed on the front cover plate group with screws.

④The transmission group is composed of main shaft, bearing tube and bearing device. The main shaft is made of high-quality steel. The overall structure of the bearing box adopts rolling bearings and is lubricated with bearing grease.

Utilization of fan

Operation is permitted only when the fan is in perfectly normal condition.

It is required to check each part of the fan for normality in case of startup of the fan upon maintenance.

The fan shall be cleaned regularly and the dust, dirt and other impurities inside conveying pipeline shall be removed at regular interval to prevent rust.

It is not allowable to repair the fan when it is in operation.

A throttling device may be used for adjustment in case of excessive flow which not in compliance with operating requirements or smaller flow required in a short time.

The fan shall be immediately stopped for inspection in case of abnormality during its startup, shutdown or operation.
