Installation and disassembly of JMZ stainless steel self-priming pump
install
1. The pump can be laid on the foundation and the position of the foot bolts can be determined according to the 'Pump Appearance Installation Dimension Table'. But it is best to wait until the pump is delivered and proceed with construction according to the size of the base.
2. The pump is installed on the foundation, and the level of the unit can be adjusted using shims. The level should also be checked with a spirit level, and the concentricity between the pump axis and the motor axis should be rechecked and adjusted. The difference between the outer circle, upper, lower, left, and right of the coupling should not exceed 0.15 millimeters when checked with a knife edge ruler and a feeler gauge. The deviation between the end faces of the two couplings shall not exceed 0.2 millimeters.
3. Pumps should not bear the weight of pipelines, and the amount of pipelines should be supported by pipeline support equipment.
4. After installation, manually rotate the coupling to see if it is easy and flexible, and if there is any jamming phenomenon.
Disassembly and assembly
1. Unscrew the four screws connecting the bearing body and pump body, and loosen the mechanical seal and pump cover at the same time.
2. Unscrew the impeller nut (turn right) to remove the impeller, key, and pump cover, and then remove the mechanical seal from the pump cover.
3. Use a slider to pull down the coupling, then remove the key, bearing end cover, and finally disassemble the shaft and bearing.
4. The assembly sequence of the pump should be reversed as described above.
When reinstalling the inlet coupling of the suction pump, please note that the water blocking valve should be facing forward to ensure a proper fit with the front of the water blocking valve and ensure self-priming effect (see the bottom right figure).
Installation of mechanical seals
When replacing mechanical seals, attention should be paid to the specifications and models that match the original ones.
During the installation of mechanical seals, cleanliness should be maintained and the sealing components should not be knocked To prevent damage and destruction.
When installing small and large sealing valves and dynamic and static rings, the surface should be coated with a layer of clean engine oil and transparent oil.
4. Install the static ring and large rubber ring into the pump cover, and then install them together on the shaft (note: the dynamic ring pin must be aligned with the drive hole of the impeller).
5. Push the ammunition seat and spring together to form a damaged assembly Using the spring seat surface as the force point, push it onto the main shaft, and the thrust should be compressed by the spring by 2-4mm before sliding on the shaft. If the spring is not yet compressed and can slide, it indicates that the fit between the dynamic ring and the main shaft is loose and the friction force is small. If the spring shrinks by more than 6mm and the dynamic and sealing rings still cannot slide on the shaft, it indicates that the fit is tight It should be checked whether the mechanical seal matches the original one.
Malfunctions and Troubleshooting of JMZ Stainless Steel Self priming Pump
|

|
Insufficient head |
1. Severe corrosion of the impeller 2. Incorrect motor configuration 3. The gap between the impeller and the pump cover is too large |
1. Replace the impeller with a new one 2. Replace the motor 3. Reduce the gap by 8 |
|
Bearing overheating |
1. Insufficient or excessive lubricating oil 2. The pump shaft and motor shaft are not concentric 3. Bearing damage 4. The bearing quality does not match |
1. Lubricating oil should be applied to 30-40% of the sealing chamber 2. Adjustment Make the pump shaft concentric with the motor shaft 3. Replace the bearings with new ones 4. Replace the low-noise bearing |
|
vibrate serious |
1. The pump shaft and motor shaft are not concentric 2. Bending of pump shaft |
1. Adjust to align the pump shaft with the motor shaft 2. Replace the shaft again |
|
seal leakage |
1. Insufficient spring pressure 2. Corrosion, wear, or scratches on the end of the moving or stationary ring 3. Corrosion and deformation of the damaged sealing ring 4. Foreign objects or crystallization of the medium affect the axial movement of the moving ring |
1. Adjust the compression amount of the spring or replace the spring 2. Repair or replace the dynamic or static ring 3. Replace the sealing ring with a new one 4. Remove crystals of foreign objects or media |
|
motor overheating |
1. The liquid has a high specific gravity and the temperature is too high 2. The mechanical seal spring is adjusted too tightly 3. Low voltage 4. Poor assembly quality, some parts experience friction, or the motor and pump are not concentric |
1. Increase the motor size 2. Adjust the compression amount of the spring again 3. Increase the voltage 4. Check the assembly quality and eliminate assembly faults |
Please provide as much as possible for ordering: 1. Model 2. Diameter 3. Head (m) 4. Flow rate 5. Motor power (KW) 6. Speed (R/min) 7. Material with accessories 8. Voltage (V)
