1) before selecting fans, it is necessary to know the production and product quality of domestic fans, such as the types and specifications of fans produced, the special uses of various products, the development and promotion of new products, etc., and fully consider the requirements of environmental protection, so as to select the best fans....

1. Before installation, check all parts of the fan. Whether the parts are complete, whether the rotation direction of impeller and casing is consistent, whether the parts are closely connected, whether the main parts such as impeller, main shaft and bearing are damaged, whether the transmission group is flexible, etc. If any problem is found, it shall be repaired and adjusted immediately....

Normal shutdown: the normal shutdown of the unit shall be operated according to the following procedures....

When we operate the FRP fan, there will be a phenomenon - the fan itself has vibration, and what causes the vibration of the distance?...

The problem that the FRP fan is afraid of in the process of use is that the equipment trips. After the trip, the equipment cannot operate, which will seriously affect the work efficiency. It is also necessary to spend time to find out the cause and maintenance, which will bring great losses to the enterprise. So what are the factors that cause the FRP fan to trip? In fact, this is mainly caused by the lack of understanding of the equipment. The main factors causing the trip of FRP fan are as follows:...

FRP roof fan is a new type of ventilation equipment made of anti-corrosion FRP material, which belongs to axial flow fan. Because the outer frame of the fan is made of anti-corrosion FRP material, the working principle is to use negative pressure to exchange air, achieve the purpose of air circulation, ventilation and cooling, so it is called FRP negative pressure fan. FRP roof fan has the characteristics of corrosion resistance, large air volume, low energy consumption, low speed, low noise and so on....

FRP fan is mainly used for ventilation in industrial and civil buildings. There are two types of FRP fan: centrifugal type and axial-flow type. The vertical installation structure of direct connection of motor can be divided into general type, explosion-proof type, temperature resistant type, humidity resistant type, corrosion-resistant type and other types according to different use conditions. The shell and impeller can be made of different materials according to actual conditions, while the hood can be made of different materials Light weight, corrosion-resistant FRP material....

The FRP fan shell is made of composite FRP material, and the blades are made of excellent aluminum alloy or PP material. The series of fans use the steel design principle to rapidly exhaust the sultry and high temperature gas around the fans. The effect of axial extraction of axial flow fan is effectively divided. This series of fans have the advantages of light weight, stable operation, low mechanical noise, not easy to aging, good corrosion resistance, simple installation, etc....

(1) single unit heat supply is large, and the number of terminal equipment used is small under the same heat load; (2) the small-scale heater can be hung without occupying the building area. The large-scale heater can be installed on the ground with limited floor area;...

Industrial heater is a kind of electric heating product which needs to be fixed on the wall or ceiling. It is suitable for workshop, garage, shop, drying room and other places. Forced air circulation by fan is conducive to air heating and temperature balance, which is suitable for intermittent heating places....
