The single-stage dust collector is installed in the vicinity of the dust-generating mechanical equipment, and the user can configure the metal or plastic dust-collecting pipe and the dust-absorbing cover according to the size of the air inlet on the dust collector.
1. The electric control box cover of the single-machine dust collector should not be opened at will during work. If it is necessary to adjust the cleaning time, or when the circuit needs to be checked, the power should be cut off after the machine is stopped.
Second, the single-machine dust collector should be vibrated and cleaned according to the nature of the dust and the capacity. In general, the vibration is repeated three to four times per shift to ensure the normal operation of the dust collector.
3. The single-machine dust collector removes dust regularly according to actual needs. When the dust in the dust collector is removed, it is only necessary to open the sealed ash door and pull out the drawer when the fan and the cleaning mechanism are stopped.
Fourth, in order to ensure that the dust removal equipment is in the best working condition, it should be as close as possible to the origin of the dust, generally 1.5 meters to 2.0 meters, the connection pipe should be as short as possible, and the elbow should be reduced as much as possible to avoid increasing the resistance loss.
5. The dust hood is the key component to ensure that the single-stage dust collector unit is in the best condition. The unit should be made according to the nature of the dust of the outer dimensions of the machined parts, in accordance with the principle of passing, near, smoothing, sealing and designing the dust cover. The ideal vacuum hood.
Sixth, the single-machine dust collector should check the inspection door, the ash door, and the air duct connection system before work to avoid leakage and reduce the vacuuming effect.
7. The voltage of the single-stage precipitator is 380 volts for three-phase AC. After the external wires on the single-stage precipitator are connected to the power supply, they can be used. When the initial rotation, attention should be paid to whether the fan is rotating forward (such as reverse rotation, air volume). Very small, need to change the power wiring).

Thrust Spherical Roller Bearing
A spherical roller thrust bearing is a rolling-element bearing of thrust type that permits rotation with low friction, and permits angular misalignment. The bearing is designed to take radial loads, and heavy axial loads in one direction.
Spherical roller thrust bearings are of separable construction, The shaft washer is assembled with the cage and a number of asymmetrical spherical rollers and has to be used along with a housing washer having sphered raceway. During mounting, the rings are to be fixed on to their respective seats – shaft washer on the shaft and housing washer on to the housing and then they have to be put together carefully They are manufactured in multiple series.
The raceway of the housing washer is at an angle with it`s ais of rotation, so as to be able to allow the rollers to remain in touch with it. As a result, a spherical roller thrust bearing is capable of carrying both a radial as well as an axial load. Spherical roller thrust bearings – because of their internal geometry – are capable of accommodating certain amount of misalignment. However, they can take axial loads only from one direction, and may need to be used in pairs in Back-to-Back or Face-to-Face arrangement, if thrust load from both the directions are to be carried.
Spherical roller thrust bearings are capable of compensating misalignment and shaft deflection.
The bearings are manufactured in normal accuracy. However, bearings with higher running accuracy can also be supplied.
