What are the precautions for daily inspection before starting Roots blower?

What are the precautions for daily inspection before starting Roots blower? Roots Blower Manufacturing Co., Ltd. is a nationally famous company focusing on Roots blower and three leaf Roots blower. Today, the small editor of the company came to have a look at the daily inspection items of Roots blower.

First of all, the bearing, lubricating oil temperature and current indication values must be frequently checked during operation. When cooling water is used for fans, check whether the cooling water volume meets the specified requirements. When sealing the fan packing, check the sealing leakage. When the leakage is serious, replace the seal immediately to avoid safety accidents caused by dangerous gas leakage, and corrosion gas leakage will also damage the bearing.

In addition, the Roots blower must be depressurized before shutdown. In case of shutdown with load or sudden power failure, the high-pressure gas in the system at the outlet side of the fan will quickly flow to the inlet side of the low fan (that is, generally speaking, backflow), thus causing the high pressure gas to drive the fan impeller to accelerate and reflect the rotation speed of the fan impeller to become higher and higher. When the speed of the impeller reaches its limit speed, it will cause a vicious accident of collision and smashing between the impeller and the casing. Especially for users transporting flammable and explosive gases such as fertilizer plants, they should operate strictly.

Next, let's share with you the daily inspection items of Roots blower: check the oil level, too much or too little lubricating oil will damage the bearing; Check the temperature of main and auxiliary oil and bearing parts; Check the suction and discharge pressure to confirm whether the fan operates normally; Check the motor load. If the motor load increases, it indicates that there is some abnormal condition. Find out the reason; Check the sealing effect of packing.

Well, that's all. If you are interested in our products, please call us for consultation.
