What are easily overlooked when using centrifugal fans

The fan is a mechanical device that boosts the air pressure and sends gas in parallel with the input of mechanical kinetic energy. It is a driven power machine. If you want to better control the centrifugal fan, you must understand the problems and some common problems of the centrifugal fan. Let's learn about it in detail below.

Wuxi Lida Fan Factory was founded in 1993, covering an area of ​​18,000 square meters and a building area of ​​9,300 square meters Modern standard workshop, with strong production and testing equipment, strong technical force. Over the years, we have cooperated closely with scientific research units and fan designers to develop and produce WZF series forward-inclining multi-blade belt-driven air-conditioning centrifugal fans.

Today, the editor of Lida Fan will tell you carefully: what are easily overlooked when the centrifugal fan is used:

The temperature of the piston pin of the centrifugal fan should not exceed 65°C. If the temperature exceeds 70°C, the machine should be turned off immediately to check whether the surface of the piston pin is damaged, and it should be ground. The point contact on the surface of the piston pin should reach 2-6 points/cm2. The pump oil temperature of the rolling bearing of the centrifugal fan is controlled at 50-60°C. If it exceeds 65°C, the temperature of the piston pin may be overheated; if it is less than 40°C, the gap of the piston pin may be too large. The pressure of the oil cooler should be lower than the steam pressure, so as to prevent the cooling circulating water from leaking into the lubricating grease and causing the oil to become moldy. Regularly check whether there are oil stars in the cooling circulating water of the centrifugal fan. If there are oil stars, they should be checked quickly Convert to a reserved cooling tower and replace leaking oil cooler elements.
