Pump before the start, it is necessary to make the pump casing and suction tube filled with water, and then start the motor, make and water pump shaft to drive the impeller for high speed rotation, water centrifugal motion, be left to the impeller outer edge and the volute pump shell of the water flow into the pump pressure.
If no, for system failure, it is recommended that the replacement IC or returned to the factory maintenance;
If the connection is line fault, and the system has a shift control signal output, we need to check the connection line whether there is open circuit or poor contact, check dc relay or ac contactor whether there is damage;
If the spindle motor damage or short circuit, we check the spindle motor can be directly;
(4) if the because of mechanical shift, not hang up the gears can be directly.
Current corrosion caused the main reason is that the potential difference between the outer and inner ring and electrostatic effect, the solution: in setting circuit, current is not through the bearing, bearing for insulation, electrostatic grounding.
Excessive axial thermal elongation (
Axial additional load bearing is statically indeterminate)
;
And on the ball or roller pressure pit (
Installed with a hammer bearing caused by)
；
, hole of the shoulder is too big,
Send the bearing seal touch misrepresenting)
；
, the shaft is too coarse to make actual fit too tight (
Cause the bearing temperature too high or noise)
；
。
Sauvy repair technology is not used by the emergency response, is a set of mature and perfect, fast, and repair technology, after the repair, use the unit in accordance with the normal process lubrication bearing, don't appear such as bearing damage, holding in death of the improper use of cases, the service life of the repaired axis can even more than the service life of the shaft itself.
Bearing ring and the shaft or small bearing shell is the transition or interference, directly with mechanical or hydraulic way, pressure into the shaft or housing, as long as the power works on interference fit of the bearing ring, be careful not to use the hammer hammer directly, through a socket to hammer the sleeve, the method of tapping the sleeve bearing is put into place.
Outer ring is truncated spherical outside surface, and the concave spherical surface of the bearing to match automatically self-aligning, arrange ushering bearing structure is compact, convenient loading and unloading, seal is perfect, suitable for simple support, are often used to.
When choosing Angle belt, should pay attention to its quality, such as thickness, width, flexible to, & amp;
emsp;
When the feed work slow moving crawl vibration will be formed.
Bearing installation install bearing, have to clean the bearing, however, clearance is too large will change the dynamic characteristics of bearings, rotor caused by unstable operation.
Cause premature fatigue;
In extreme cases, countermeasures: below the oil level should be slightly below the center of the roller, bearing grease filling about/to/space in the box.
Some motor factory in recent years on the adoption of two ball bearing pole motor using large clearance ball bearing, bearing heat makes it is ease for runtime clearance measures of reducing incur bearing damage.
Countermeasures: change meets the design requirements of aperture bearing box, if that is the catastrophic damage, LTD bearing to determine the root cause of the problem, because may be outside lubrication factor.
