When the roots blower is used, it is necessary to maintain the transmission belt. After 24 hours of use, the belt tension is adjusted. After a week's use, the belt tension needs to be adjusted again. Under normal circumstances, the new belt can be replaced in about a year. This is the routine maintenance of Roots blower belt. So, let's find out what causes the loose belt of Roots blower. What happens to the loose belt and how to do it.

羅茨風機皮帶會出現(xiàn)松動的原因，一般如下，皮帶老化、溫度過高、型號不符以及生產(chǎn)安裝問題，跟著小編來了解一下吧。

The reasons for looseness of Roots blower belt are generally as follows: belt aging, high temperature, inconsistent model and production and installation problems. Follow Xiaobian to understand.

原因之一：皮帶對于羅茨鼓風機來說是消耗品，羅茨鼓風機運行中皮帶會被拉伸，出現(xiàn)變松的現(xiàn)象，這種情況屬于正常，及時調(diào)整張緊度即可，當三角帶使用時間更長時，會出現(xiàn)老化的情況，皮帶會慢慢的損耗，出現(xiàn)邊變松、破裂甚斷裂的現(xiàn)象，則需要進行更換上新的皮帶。

One of the reasons: the belt is a consumable for the roots blower. During the operation of the roots blower, the belt will be stretched and become loose. This is normal. Adjust the tension in time. When the triangular belt is used for a longer time, it will be aged, and the leather belt will be slowly worn out. If the edge becomes loose, broken or even broken, it needs to be replaced with a new belt.

原因之二：羅茨鼓風機運行中，皮帶在高速運轉(zhuǎn)，皮帶與皮帶輪之間的摩擦會發(fā)熱；反過來，羅茨風機過熱也會導致皮帶熱上加熱，尤其是夏天溫度較高。還有，如遇到羅茨風機故障，比如，管道阻塞、壓力增加、潤滑油過多、葉輪墻板機殼間摩擦等，這些故障都會導致羅茨風機過熱，會將熱量傳遞到皮帶，讓皮帶變得更加的松。這種情況下需要先解決羅茨風機過熱的情況，在巡檢過程中，排除管道阻塞、壓力增加、潤滑油過多、葉輪墻板機殼間摩擦的情況。皮帶摩擦熱加上羅茨風機運轉(zhuǎn)本身產(chǎn)生的熱量，造成皮帶損耗加劇，更容易出現(xiàn)皮帶變松。

The second reason: during the operation of Roots blower, when the belt is running at high speed, the friction between the belt and the pulley will heat up; Conversely, overheating of Roots blower will also lead to belt heating, especially in summer. In addition, in case of Roots blower faults, such as pipeline blockage, pressure increase, excessive lubricating oil, friction between impeller wallboard and casing, these faults will lead to overheating of Roots blower and transfer heat to the belt, making the belt more loose. In this case, the overheating of Roots blower needs to be solved first. In the process of patrol inspection, the situations of pipeline blockage, pressure increase, excessive lubricating oil and friction between impeller wallboard and casing need to be eliminated. The friction heat of the belt and the heat generated by the operation of Roots blower aggravate the loss of the belt and make it easier for the belt to become loose.

原因之三：羅茨鼓風機皮帶變松的原因還可能是皮帶與皮帶輪不符，尤其是更換上新的皮帶時，如果更換皮帶型號不符，如槽型不對或者長度不符，都會造成出現(xiàn)變松的情況，遇到這種問題，需要更換型號相符的皮帶。

Reason 3: the loose belt of Roots blower may also be due to the inconsistency between the belt and the pulley, especially when replacing a new belt. If the replacement belt model is inconsistent, such as the wrong groove type or length, it will lead to looseness. In case of this problem, it is necessary to replace the belt with the same model.

原因之四：羅茨鼓風機質(zhì)量問題，如果風機廠家生產(chǎn)中出現(xiàn)問題，風機生產(chǎn)和安裝精度達不到，兩皮帶輪不在同一水平面上或者間距不合適，羅茨風機在運轉(zhuǎn)中皮帶很容易變松，這種情況需要對風機機頭和電機進行調(diào)整，將機頭與電機的帶輪調(diào)整到合適的位置，然后更換皮帶，再對皮帶進行調(diào)整即可。

Reason 4: the roots blower has quality problems. If there are problems in the production of the fan manufacturer, the fan production and installation accuracy cannot be reached, the two pulleys are not on the same horizontal plane or the spacing is inappropriate, and the belt of the roots blower is easy to become loose during operation. In this case, it is necessary to adjust the fan head and motor, adjust the pulley of the head and motor to the appropriate position, and then replace the belt, Then adjust the belt.
