Before the hot oil pump is started, the pump casing is filled with the liquid being transported; after the start, after the start, the impeller is driven by the shaft to rotate at a high speed, and the liquid between the blades must also rotate. Under the action of centrifugal force, the liquid is thrown from the center of the impeller Get energy from the outer edge, leave the outer edge of the impeller at high speed and enter the volute pump casing.
The assembly sequence of the Thermal oil pump:
One, install the bearings on the bearing box and the bearing seat respectively.
Second, install the felt ring on the bearing end cover A, C and the bearing box.
Three, install the bearing end covers B and C on the bearing seat and tighten them with bolts.
Fourth, put the bearing box with the bearing on the shaft, screw on the round nut, and fasten the bearing end cap to the bearing box.
5. Install the shaft into the bearing seat, fix it with bolts, screw on the adjusting screw, install the bearing seat on the bearing seat, and place the water retaining ring in the appropriate position at the lower bearing.
6. Fix the connecting pipe on the bearing seat, install the pump cover under the connecting pipe, install the impeller on the lower part of the shaft and tighten it, install the front cover of the pump body in turn, and fix it with bolts, and adjust with the adjusting screw at the bearing box The gap between the impeller and the front cover (control within 1~1.5mm) is adjusted with nuts and bolts.
Seven, the motor support is installed on the bearing seat with bolts, the coupling part is installed on the upper end of the shaft, and the motor coupling is fastened to the motor shaft head with fastening screws, and the motor is installed on the motor support and used Bolts and nuts are tightened.
