The vertical turbine pump is circulating water pump, located in the circulating water system, and the over-flow medium is sea water. The function is to provide flushing water for the drum-type rotating filter to ensure that impurities and sea creatures are washed away in time, thus bringing clean seawater downstream. The vertical turbine deep well pump is installed in the seawater water intake platform outside the circulating water pump room, and the seawater is sucked from the drum filter pool. The water outlet is equipped with a backwash filter and a globe valve, and external industrial water supplies cooling water to the packing of the pump when the pump is started.
The vertical turbine deep well pump is mostly a vertical single-suction multistage centrifugal pump. The impeller is installed below the moving water level in the well. The power machine is placed on the well. The impeller is driven by the long shaft to rotate in the diversion shell. The water flows along with the diversion shell and the impeller. The flow path between them is lifted up to the ground via the water pipe. When the head is high, a multistage centrifugal pump with multiple impellers in series can be used.
Vertical turbine deep well pump faults and corresponding treatment measures:
First. The main pump is a water pump. When the pump is running, it will inevitably cause malfunction and damage, resulting in failure to pump water normally. Therefore, When it is found that the pump is pumping poorly, it must be repaired and adjusted in time.
Second. non-absorbent or water drainage at the end of the causes for the stuck valve, part of the blockage of water, high water or water leakage is too high. It may also be caused by improper steering, blocked impeller flow path, e After checking through them one by one, can be taken at the end of valve repair, clear the blockage and to correct steering, cleaning and other measures to deal with the impeller.
Third. Pipe leakage or leakage that may be installed when the nut is not screwed tight. If the leakage is not serious, may leak or leaks in the local smear cement, asphalt or coated with oil mixing the cement slurry. The temporary repairs can be more wet mud or soft soap. If the joint leaks, then tighten the nut wrench can be used, must be serious leakage disassembly.
Fourth, Fill more than overheating due to tight packing weight, less than the cooling water into the filler, or damaged shaft surface. Can be relaxed to take appropriate fill tube plug seal clearance. Fill the wear and tear must be replaced with new ones. With pre-installed in the oil soaked, turn-by-turn into the incision to be staggered, so that leakage can be reduced. Fill the last lap after installed, loading pressed to cover operation for further adjustment of tightness.
Fifth. Rattling electric pump rotor may be uneven, or combination of bad coupling, bearings wear bending; also cause loose or break some parts, also because of other reasons that pipe support is not strong. Can be taken adjustment, repair, strengthening, alignment, such as approach to the replacement.
Sixth. Teardown and repair of the impeller. The impeller blades are damaged or affected by cavitation, etc., should be replaced or plated with hard alloy. Little wear and tear, it can be poured up. When disassembling, to fix the impeller and the pump shaft first, loosen the nut or turn the head screw, and then turn the ejector screw to gradually pull out the transmission. Then remove the shaft from the pump casing, And then removed the pump shaft shell removed send impeller repair shop repair.
Seventh. Shaft repair defects due to the impact of multi-shaft bending load, belt pull too tight or causing incorrect installation. If the bend is not much that can be used to manually screw appliance to correct, but not too hard. If the cracks or split off shaft can take when welding, welding or CALCINED access, and then by tempering, to grinding turning.
The vertical turbine pump has been improved in hydraulic design and has been developed for various industries such as fire-fighting equipment. Efficient, reliable and sturdy are the main advantages of this series. The VT series has motors, which are linked to the internal combustion engine through gearboxes. Various types of pumps are available to meet customer needs. Follow us, learn more information.
