First, the 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 on the pipelines to complete the installation. 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.
Second , SG-type pipe pump troubleshooting methods:
malfunction | the reason | Method of exclusion |
No water pump | Injected into the water pump is not enough, the rotation of the wrong direction, the impeller flow blockage. | Fill the water pump again, the transmission impeller runner, adjust the rotation direction. |
2. The pump flow is insufficient | Partial pump blockage, the number of revolutions is too low, the total lift above the pump rating, impeller damage. | Clean the pump and pipe, replace the impeller, increase the pump shaft rotation, adjust the outlet valve. |
3. Outlet pressure is not enough | Liquid in the air, the 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 and so on, the pump is working under too much flow that the pump 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. |
Pump vibration | Pipeline system support is not good, part of the impeller blockage caused by 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. |
Pump leaks | Damaged mechanical seal, 0-ring damage, pump body leakage. | Replace the mechanical seal and 0 ring, welding pump body leakage. |
7. Pump miso tone is too heavy | Bearing overheating lack of oil, pump overload. | Bearing Department refueling, according to 4 excluded. |
malfunction
the reason
Method of exclusion
No water pump
Injected into the water pump is not enough, the rotation direction is wrong, the impeller flow blockage.
Fill the water pump again, the transmission impeller runner, adjust the rotation direction.
2. The pump flow is insufficient
Partial pump blockage, the number of revolutions is too low, the total lift above the pump rating, impeller damage.
Clean the pump and pipe, replace the impeller, increase the pump shaft rotation, adjust the outlet valve.
3. Outlet pressure is not enough
Liquid in the air, the 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 and so on, the pump is working under too much flow that the pump 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.
Pump vibration
Pipeline system support is not good, part of the impeller blockage caused by 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.
Pump leaks
Damaged mechanical seal, 0-ring damage, pump body leakage.
Replace the mechanical seal and 0 ring, welding pump body leakage.
7. Pump miso tone is too heavy
Bearing overheating lack of oil, pump overload.
Bearing Department refueling, according to 4 excluded.
Temperature Water Sprinkling Dust Reducing
Dust control is needed during many activities at the Site for health and safety purposes and to prevent contaminant dispersal via atmospheric transport. Spraying of water is the baseline approach at the Site for dust control in most applications, including use during excavation activities, on roadways and disturbed areas, for facility demolition, and during construction activities. Use of water at or near waste sites may introduce infiltration to the subsurface. As such, the recharge rate ( hydraulic driving force) through the vadose zone and to the groundwater may be increased by an extent related to the duration and amount of water applied. An increased recharge rate can increase contaminant fluxes toward the groundwater and potentially induce lateral movement depending on the magnitude of the recharge rate. Thus, dust suppression via water spray is of potential concern for contaminants in the vadose zone.
