　　羅茨鼓風機的軸承拆除有以下5鐘方法

　　1.敲擊法。是一種*簡單、*常見的軸承拆卸方法。借助錘擊的力量使相互配合的零件產生位移而相互脫離，實現拆卸。采用敲擊法拆卸軸承時，敲擊力不應施加在軸承的滾動體和保持架上，一般應施加在軸承內圈，這種拆卸方法簡單易行，但常會損壞零件,甚至達不到拆卸的目的。

　　⒉.拉出法。利用2爪或3爪拉馬等工具拆卸軸承，采用拉出法軸承受力均勻，拆卸力的大小和方向容易控制，適用于軸承與軸配合過盈量較大的情況。這種方法損壞零部件的概率較小。

　　3.推壓法。利用壓力機將軸承推出，優點是工作可靠，對機器和軸承的損傷小。拆卸時壓力機的著力點應保持在軸的中心，墊塊抵住軸承內圈。

　　4.熱拆法。用熱拆法拆卸軸承時，首先應將拉具安裝在準備拆卸的軸承上，并提供一定的預拉力。用高溫機油(100°℃左右)反復淋澆在軸承上，軸承圈受熱膨脹后改變與軸的配合過盈量。如需拆卸軸承較少或沒有大量機油，可以采用噴槍烘烤的方式，但要注意軸承加熱時溫度不能太高且火焰不能對著軸，防止軸受熱后材料組織結構變化。

　　5.液壓法。適用于尺寸較大且配合很緊的軸承，使用液壓拆卸時軸上應有預制孔。液壓拆卸工具主要有液壓泵、液壓管、壓力表及接頭等，并需要配合拉馬使用。操作時壓力應緩慢升高，聽到軸承與軸分離的聲音后，使用拉馬等工具拆卸。如在打壓過程中壓力已升的很高，但始終沒有分離，應首先泄壓，避免壓力過高出現設備損壞、人員受傷等情況。

　　羅茨鼓風機更換油封的方法

　　三葉羅茨風機更換軸承，在拆卸過程中，難免會傷害到油封!即使傷害不大，但經理了拆卸與長期運轉后的油封，密封效果與壽命會大打折扣!因此，更換三葉羅茨風機軸承時，也要更換相應的油封!

　　羅茨鼓風機的油封組通常由3~4個骨架油封組合而成，其中兩個油封背靠背地裝在與被輸氣體接觸的內側，另一個(或兩個)裝在外側。全部元件裝在一個密封座中，成為一個密封組，中間可注脂潤滑。骨架油封組屬于接觸型密封，容易造成軸(與油封唇口接觸部位)的磨損。但由于結構簡單，裝拆方便，成本低廉，密封效果比較好，以及對工作環境和維護保養要求不高,實際中一直具有較廣的應用。

　　請定時查看機油以及黃油，并及時補給，機油新風機運轉一周后應**次替換新油，一個月后第2次替換新油，今后每半年替換一次，夏天降臨前必換(220#中負荷工業齒輪油)。黃油每兩周加一次(組成鋰基潤滑脂ZL-3H)。

　　一般羅茨鼓風機只要一個油封，安在孔蓋里。高壓氧化風機有6個油封。四個軸承各一個(相當于密封圈)，壓蓋上兩個。三葉直聯氧化風機開機前:開機前留意油位，機油注入量請到達油窗指示紅點方位。

　　羅茨鼓風機的油封安裝方法

　　1.如果羅茨鼓風機一個油封座里同時安裝有兩個油封時，不能將其疊在一起一次性壓入;應先把其中一個油封壓裝到指定位置，然后裝另一個油封;

　　2.油封安裝時，主要不要弄錯油封的安裝方向，應將油封工作面指向需要密封的一側;

　　3.當羅茨鼓風機油封安裝時，唇口通過鍵槽、螺紋及軸肩等刃口部位時，應使用金屬導套或薄綱片卷筒予以保護;

　　A: as a fan equipment with high load operation, the bearing damage of the three leaf roots blower is inevitable! If the fan is purchased from our company, you can call 400-155-8689 to contact our customer service, and report the damage of Roots fan. The customer service will arrange the corresponding after-sales master to communicate with you according to your fan model, and decide whether to repair it on site or return to the factory! Of course, if you have relevant mechanical maintenance personnel in your factory, you can also purchase corresponding bearing accessories through us! Then disassemble and repair the three leaf roots blower by yourself! Next, I will share with you the disassembly methods and parts replacement methods of the bearings of the three blade roots blower!

　　What if the bearing of the three leaf roots blower breaks down

　　The bearing removal of Roots blower has the following 5-hour methods

　　1. Percussion method. It is the simplest and most common bearing disassembly method. With the help of the force of hammering, the matched parts are displaced and separated from each other to realize disassembly. When using the knocking method to disassemble the bearing, the knocking force should not be applied to the rolling element and cage of the bearing, but should generally be applied to the inner ring of the bearing. This kind of disassembly method is simple and easy, but it will often damage the parts and even fail to achieve the purpose of disassembly.

　　⒉. Pull out method. Use 2-jaw or 3-jaw puller and other tools to disassemble the bearing. The pull-out method is adopted. The bearing bearing force is uniform, and the size and direction of the disassembly force are easy to control. It is suitable for the case of large interference between the bearing and the shaft. This method has a low probability of damaging parts.

　　3. Push method. Using the press to push out the bearing has the advantages of reliable operation and little damage to the machine and bearing. During disassembly, the force point of the press should be kept in the center of the shaft, and the cushion block should be against the inner ring of the bearing.

　　4. Hot disassembly method. When disassembling the bearing with the hot disassembly method, first install the puller on the bearing to be disassembled and provide a certain pre tension. Pour high-temperature engine oil (about 100 ° ℃) on the bearing repeatedly, and change the fit interference with the shaft after the bearing ring is heated and expanded. If the bearing needs to be disassembled with little or no large amount of oil, it can be baked with a spray gun, but it should be noted that the temperature of the bearing should not be too high and the flame should not face the shaft when it is heated, so as to prevent changes in the material structure after the shaft is heated.

　　5. Hydraulic method. It is applicable to bearings with large size and tight fit. Prefabricated holes shall be provided on the shaft when hydraulic disassembly is used. Hydraulic disassembly tools mainly include hydraulic pumps, hydraulic pipes, pressure gauges and connectors, which need to be used with pullers. The pressure should rise slowly during operation. After hearing the sound of separation between the bearing and the shaft, use puller and other tools to disassemble. If the pressure has risen very high but has not been separated, the pressure should be relieved first to avoid equipment damage and personal injury caused by excessive pressure.

　　Method of replacing oil seal of Roots blower

　　When replacing the bearing of the three blade roots blower, it is inevitable to damage the oil seal during the disassembly process! Even if the damage is not great, the seal effect and service life will be greatly reduced if the oil seal is disassembled and operated for a long time! Therefore, when replacing the bearings of the three blade roots blower, it is also necessary to replace the corresponding oil seal!

　　The oil seal group of Roots blower is usually composed of 3-4 skeleton oil seals, of which two oil seals are installed back-to-back on the inner side in contact with the transmitted gas, and the other (or two) is installed on the outer side. All components are installed in a sealing seat to form a sealing group, and the middle can be greased and lubricated. The framework oil seal group is a contact seal, which is easy to cause the wear of the shaft (the part in contact with the oil seal lip). However, due to its simple structure, convenient assembly and disassembly, low cost, good sealing effect, and low requirements for working environment and maintenance, it has been widely used in practice.

　　Please check the oil and butter regularly and replenish them in time. The new oil should be replaced for the first time after the oil fresh air fan runs for a week, and for the second time after a month. In the future, it should be replaced every half a year. It must be replaced before summer comes (220 × medium load industrial gear oil). Add butter every two weeks (form lithium grease zl-3h).

　　Generally, roots blower only needs an oil seal, which is installed in the hole cover. High pressure oxidation fan has 6 oil seals. One for each of the four bearings (equivalent to a sealing ring) and two on the gland. Before starting up the three leaf direct connected oxidation fan: pay attention to the oil level before starting up, and the oil injection volume should reach the direction of the red dot on the oil window.

　　Installation method of oil seal of Roots blower

　　1. If two oil seals are installed in one oil seal seat of Roots blower at the same time, they cannot be stacked together and pressed in at one time; Press one oil seal to the specified position first, and then install the other oil seal;

　　2. When installing the oil seal, do not make a mistake about the installation direction of the oil seal, and point the working surface of the oil seal to the side that needs to be sealed;

　　3. When the roots blower oil seal is installed, when the lip passes through the key slot, thread, shaft shoulder and other cutting edge parts, it should be protected with a metal guide sleeve or thin steel sheet drum;
