1. units are usually equipped with three phase motors when they are pumped out of the factory. The users are connected to the 380V power supply, and they can be used correctly. (if a single phase motor is needed, it should be explained at the time of order that the single phase motor can only be used with 220V power supply.)
2. before the first use of the pump, the pump body must be filled with the solution from the exhaust rob. Tighten Rosie and press the steering mark to start the motor. According to the difference of suction range, it usually takes 2~4 minutes to automatically discharge air and transport liquid. Next time, no irrigation is needed. When the pump is not used for a long time, we should first open the water and check whether there is a liquid in the pump body. If it is not enough, please fill it up.
3. no liquid in the body of the pump, starting motor, in order to prevent mechanical seal friction, fever and burn.
Before the 4. pump starts, it is applied to the rotating coupling to check whether the rotation is flexible. If the resistance is large, the reason should be found out and the switch can be started after treatment.
5. after operation, observe whether there is leakage in the sealing part. If there is a slight leakage, it can let it run for 10~20 minutes. When the end surface of the ring is running smoothly, it can generally be solved, otherwise it should be disassembled and checked one by one for reinstallation.
6., transport acid concentrated slurry. After parking, rinse with water, so as to reduce the corrosion of accumulating acid and alkali liquids to pump and pipeline, especially avoid depositing on the sealing ring.
7. spindle pump and rotating parts should be kept clean, every year to add 2~3 bearing body butter, butter to fill the room number 40%.
8. motor on the pump, please pay attention to moisture-proof, corrosion prevention, replacement of motor, the capacity of the new motor and the speed must be consistent with the original.
JMZ, FMZ self suction pump - self-priming chemical pump installation and disassembly:
1. pump by “ pump dimensions ” for the foundation and determine the position of the foot bolt. But when the best pump is transported to the site, it is carried out according to the base size.
Construction.
2. pump is installed on the basis of available iron pad adjustment unit level, with level instrument to check the pump and motor shaft, to check and adjust the pump and motor shaft with the axis of knife edge ruler and the feeler to check the pump coupling and the outer circle and the upper and lower, left and right margins are not more than 0.15 mm. The deviation of the end gap of the two coupling does not exceed 0.2 mm.
3. do not apply the pump to bear the weight of the pipeline, the weight of the pipeline should be supported by the pipeline support equipment.
4. it is easy and flexible to rotate the coupling by the end of the installation, and there is no stagnation.
The disassembly of the pump:
1. screw down the four screws connecting the bearing body to the pump body, and the mechanical seal and the pump cover are loosened in the old time.
Unscrew the 2. screw impeller Tom (right hand) remove key and impeller, pump cover, and then the mechanical seal cover is removed from the pump discharge.
3. with Lazila coupling under and remove the key bearing shaft and the bearing will overflow, finally opened.
The assembly order of the 4. pump is carried out on the contrary.
5. when the inlet of the self-priming pump is reloaded, please note that the water resistance valve should be directed to the front to ensure the white suction effect with the front of the water resistance valve (see right below).
Mechanical seal installation:
1. change the mechanical seal, should pay attention to the specifications, the model should be consistent with the original.
2. in the process of installation of mechanical seals, it should be kept clean, not allowed to knock seal original parts, in order to prevent damage and damage.
3. the shaft surface should be coated with clean oil and transparent oil on the shaft surface.
4. put the static ring and large rubber ring into the pump cover, and then together - mounted on the shaft (notice: the ring pin must be aligned with the drive hole of the impeller).
5. the spring seat, a spring and a push ring, one end point as to the spring seat, push it on the spindle, the thrust to spring compression 2— 4mm on the shaft sliding is appropriate. If the spring has not yet been compressed, it can slide. It means that the dynamic ring and spindle match loosely, and the friction force is too small. If the spring compression is more than 6mm, the moving ring and the sealing ring can not slide on the shaft.
