What is the reason for the loose belt of Roots blower? How to solve

During the use of Roots blower, it is necessary to maintain the drive belt. After 24 hours of use of the new blower, adjust the belt tension. After one week of continuous use, it is necessary to adjust the belt tension again. Generally, a new belt can be replaced in about one year. This is the routine maintenance of Roots blower belt. Then, let's find out what causes the loose belt of Roots blower. What should we do if the belt is loose.

The reasons for the looseness of Roots blower belt are generally as follows: belt aging, high temperature, model inconsistency and production and installation problems. Follow the small editor to find out.

One reason: The belt is a consumable for Roots blower. The belt will be stretched and loose during the operation of Roots blower, which is normal. Adjust the tension in time. When the V-belt is used for a longer time, aging will occur, and the leather belt will slowly wear out and become loose, cracked or even broken, Replace the belt with a new one.

The second reason is that when the roots blower is running, the belt is running at high speed, and the friction between the belt and the pulley will generate heat; Conversely, overheating of Roots blower will also lead to belt heating, especially in summer. In addition, in case of Roots blower failure, such as pipe blockage, pressure increase, excessive lubricating oil, friction between impeller wallboard casings, etc., these failures will lead to overheating of Roots blower, which will transfer heat to the belt and further cause belt relaxation. In this case, it is necessary to solve the overheating problem of Roots blower first. During the patrol inspection, it is necessary to eliminate the pipe blockage, pressure increase, excessive lubricating oil, and friction between the impeller wallboard and casing. The belt friction heat and the heat generated by the operation of Roots blower will aggravate the belt loss and make it easier for the belt to relax.

Cause 3: The belt of Roots blower may also be loose because the belt is inconsistent with the pulley. Especially when replacing a new belt, if the belt model is inconsistent, such as the groove type or length is inconsistent, the belt will be loose. In this case, the belt with the same model needs to be replaced.

Cause 4: Roots blower has quality problems. If the fan manufacturer has problems in production, the fan production and installation accuracy cannot be reached, the two pulleys are not on the same horizontal plane or the spacing is not appropriate, the belt of Roots blower is easy to relax during operation, and the fan head and motor need to be adjusted in this case, Adjust the pulley of the head and motor to the proper position, then replace the belt, and then adjust the belt.

The condition that causes belt slack Confirm submission There are no more than the above four types, and the more common one is the aging of the belt. So, what should we do if the belt is slack.

Looseness of roots blower belt will directly lead to belt slipping. When the belt slips, it means that the rotation speed of roots blower is affected and reduced, and the output air volume of roots blower is naturally insufficient, so it is necessary to timely adjust the belt tension and replace a new belt; In addition, the belt slipping will cause the temperature of the fan to rise, the friction between the belt and the pulley will increase, the temperature will rise, and the loss will increase. Therefore, if it is found that the belt is loose during use, the tension should be adjusted in time. If there is insufficient air flow and temperature rise, it should also consider whether the belt is a problem and check the belt; Loose belt is also easy to fall off. The loose belt, coupled with the vibration during the operation of Roots blower, is easy to fall off the belt, causing accidents or failures, and even impeding the normal operation of the whole system. Therefore, it is very necessary to install a belt protective cover.
