Shanghai water ring vacuum pump bearing and coupling assembly

Shanghai water ring vacuum pump is used to extract underground biogas vacuum pump. It is usually used in the mine of high negative pressure. Is one of the most important equipment of rolling bearing and coupling of the two components. Both have complementary effect, need to be assembled at the same time, the assembly method introduces below:

1, coupling, coupling assembly to the drive shaft and driven shaft connected device. It is divided into the coupling of the motor and pump coupling.

2, during installation, the two 200 - 1 must be concentric, and both ends must be kept between the equal axial clearance. Otherwise it will seriously affect the operation of the machine and longevity. Therefore, find the coupling is an important part of assembly work. Ring.

3, coupling of axial clearance requirements:

two coupling between uniform axial clearance shall be maintained. This is to prevent the two coupling in the collision in the process of operation, and can pass feeler check clearance size, usually 4 - may be used 6 mm feeler.

4, coaxial to not require coupling:

1) the pump shaft and motor shaft axis should be in a straight line. If there is a certain slope, the machine will run, vibration and noise, result in bearing wear and affect the service life of the machine.

2. When installing a two and a half coupling, as a result of two and a half coupling cylindrical are equal in size, so you need to use different axis direction, so you can check different axis direction by cylindrical.

3. So, check on, under, left and right four position, until they are tightly closed and no gaps. Not the coaxial degree of the coupling is not more than 0. 5 mm.

(4) inspection method is in two and a half coupling put a ruler on the cylindrical, observe whether ruler is close to the two cylindrical shaft coupling.

5. Two coupling is not concentric, because a coupling firmly fixed, but another coupling have clearance, suggesting that need to be adjusted

2, rolling bearing assembly method 1, water ring vacuum pump assembly depends on the rolling bearing of rolling bearing and the interference of the journal or bearing hole. When the disturbance is small, use force fit method.

2, when using thermal filling method, bearing in oil heating, oil temperature should be lower than 100 ℃, and removed from the oil shall be immediately after put it in a journal.

3, when using pressure into the method for assembly, you can use the copper bar and the inner ring hammer symmetrically in a certain order impact, or you can use the soft metal sleeve will be pushed to or use of the news.

Shanghai water ring vacuum pump running without help of the internal components. Among them, the equipment is very important two rolling bearings and couplings. Both are mobile. Please strictly carry out the following steps to avoid improper installation.
