2. Install a mechanical seal on the motor shaft, add a small amount of clean turbine oil or 20 oil on the surface of the mechanical seal with static and dynamic fit.
3. Install impeller, fasten with impeller nut.
4. Install "0" ring, the pump body and the motor cover bolted words. Note that the gap between the impeller front cover and the pump body is 2 × 0.5 mm, and the impeller inlet outer ring and the pump body ensure a certain running clearance.
5. Disassembly order is the opposite.
Installation and use 1. Use rubber gaskets and bolts to connect the flanges on both ends of the pump body to the flanges of the pipelines. In order to facilitate the use and maintenance, the pump inlet and outlet pipelines should be equipped with a control valve.
2. Open the inlet regulator , allowing water to enter the pump to keep the sealed chamber full of liquid (otherwise it will damage the seal) and close the outlet valve.
3. Turn on the power, jog to determine the correct steering.
4. Turn to determine, the pump starts, run.
5. Adjust the outlet valve opening so that the pump runs around the design point, depending on the pump's rated flow and near the head. For this purpose, it is best to install a pressure gauge near the outlet flange. Note: The pump is strictly prohibited running water, so as not to damage the seal.
Troubleshooting Remedy 1. Insulation pump water injection Insulation pump water is not enough, the rotation direction is wrong, the impeller flow blockage.
Go to the insulation pump water, transfer impeller runner, adjust the rotation direction.
Insulation pump flow Insufficient insulation pump part of the block, the number of revolutions is too low, the total lift above the pump rating, impeller damage.
Cleaning insulation pumps and pipes, replace the impeller, increase the number of insulation pump shaft rotation, adjust the outlet valve.
3. Outlet pressure in the liquid air, speed is too low, impeller damage, the outlet valve opening too large.
Exclude the liquid air, increase pump speed, replace the impeller, adjust the small outlet valve.
4. pump power consumption is too large (motor fever) Mechanical defects such as running clearance is too small, the motor shaft bending, bolts loose, the pump is too much work flow under the pump that is far below the rated head work.
Check hiss? Block branded Barium Barium è°ƒ ??? Adjust the outlet valve so that the pump at rated flow and lift near the work.
5. Insulation pump vibration piping system is not good support, impeller blockage caused by an imbalance, resulting in cavitation, the liquid in the air.
Check? Suck Mi С Norway? Tighten the nut, the impeller through the transmission to balance, remove the air.
6. Insulation pump leakage mechanical seal damage, 0-ring damage, pump leakage.
Replace the mechanical seal and 0 ring, welding pump body leakage.
7. Insulation pump bass noise overweight bearings overheating, insulation pump overload.
Bearing Department refueling, according to 4 excluded.
