, PM running a series of vertical foam pump. The following steps should be checked before starting the pump motor starter group ⑴ pump shall be installed on a solid foundation, and tighten all the bolt to bear the full weight of the pump to eliminate vibration. ⑵ pipeline using a separate support, and should be concentric with the pump flange. ⑶ by hand when the pump shaft rotation direction, shaft driven impeller movement, there should be no friction foam pump manufacturers, or should adjust the impeller clearance. ⑷ breaking connection between the pump and motor, check motor steering, to ensure that the pump rotates in the direction of the arrow marked on the pump. Note that the pump does not allow reverse rotation, otherwise screw impeller trip, causing damage to the pump. Foam pump supply belt to be applied to the belt drive ⑸ certain preload; shaft should be parallel with the motor shaft, so that is consistent with the direction of the V-belt pulley end face, so as not to cause severe vibration and wear. When Direct drive: shaft and motor shaft to be precise alignment may cause vibration or cause damage to the bearings. Impeller adjustment in order to ensure efficient operation of the pump must be timely adjustment of clearance between the impeller and the guard plate. Proceed as follows: stop the pump, loosen bolt bearing body; between the bearing body and bin junction plus adjusting pads, the bearing assembly will move up, while the direction of rotation by hand operated pump shaft until the impeller and minor fender rubbing up; tighten clamping screw, re-check the impeller rotation is normal. For metal-lined pump foam pump model, impeller and fender gap of 0.5-1 mm. Rubber lined pump, the bearing assembly is moved downwardly into contact with the sheath of the impeller, based on the total amount of movement of the bearing assembly, taken as half of this gap between the impeller and the sheath of the foam pump stops pumping method; as far as possible before the pump stops so pumped for a water, to clean the slurry flows through the pump, and then click Close incoming valve, pump outlet valve.
