Question:

What is the clearance between the sleeve and the bearing of the shield pump?

What is the clearance between the sleeve and the bearing of the shield pump?

Answer:

Generally, when leaving the factory, bushings and bearings clearance of about 0.1 millimeters, clearance wear more than 1 millimeters, you need to change.
That is to say, the shield pump shaft sleeve and bearing clearance 0.1-1 mm range can be used normally.
Bearing: bearing bearing, used to determine the relative position of the rotating shaft with other parts, and to support or guide the parts. Its main function is to support the mechanical rotating body, in order to reduce the equipment in the transmission process of mechanical load, friction coefficient. According to the friction properties of moving elements, the bearings can be divided into two types: rolling bearings and sliding bearings.
Generally, when leaving the factory, bushings and bearings clearance of about 0.1 millimeters, clearance wear more than 1 millimeters, you need to change.That is to say, the shield pump shaft sleeve and bearing clearance 0.1-1 mm range can be used normally.Of course, according to the power of motor, the value is slightly different, the motor power is large, the normal gap allows a slightly larger range
