First, the insulation pump installation Assembly and disassembly 1. All parts to be installed scrub clean. 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, in the pump inlet and outlet piping should be installed 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. Second, the cause of the insulation pump Troubleshooting 1 Insulation pump is not water Insulation pump into the water is not enough, the rotation direction is not, 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 the mechanical part of the timely adjustment process, adjust the outlet valve so that the pump in the vicinity of the rated flow and lift 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 the pump support sector, tighten the nut, impeller impeller to balance, to exclude air traffic. 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.
Deep Groove Ball Bearing
Deep groove Ball Bearing is the most representative structure in rolling bearing, which is widely used. In addition to radial load, this kind of bearing can also be loaded with bidirectional axial load. The friction torque is small, and it is most suitable for adjusting rotation, low noise and low vibration. Bearings are widely used in automobile, electrical, instrumentation, construction machinery, agricultural machinery and various professional machinery. This kind of bearing has open and closed deformation structure. 
Deep groove ball bearings consist of an inner and outer ring with a cage containing a complement of precision balls. The standard Conrad-type bearing has a deep-groove construction capable of handling radial and axial loads from either direction in versatile designs that permit relatively high-speed operation.
