GERMANY KAYSEN PUMP CO .,LTD
The long-axis deep well pump is mostly a vertical single-suction multi-stage 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 the diversion shell and the impeller. The flow path between them is lifted up to the ground via the water pipe. The pump has a long service life and maintenance period, is widely used, and can be used in harsh environments, and is also extremely convenient for maintenance.
●The transmission parts and lubrication parts are reliably protected by the protective tube
The protective tube structure is adopted to make the conveying medium flow outside the protective tube, and is not in contact with the transmission component and the lubricating component, and does not affect the transmission component and the lubricating component of the pump due to the foreign matter contained in the pump conveying medium containing mud sand, iron oxide scale and oil stain.
●Special lubrication method and bearing structure ensure long-term stable operation of the pump
In addition to the conventional rubber guide bearing, the pump bearing also uses graphite bearings and hard alloy bearings according to special needs to improve the wear resistance and temperature resistance of the pump.
The lubrication method of the pump can be used to lubricate the lower bearing of the pump with 2~3kg/cm2 tap water (clean water) depending on the environmental conditions. In the special environment without running water (clean water), the pump adopts self-lubricating method: one is lubricated with calcium-based grease, which is completely advanced technology. The pump can be used in any special environment. Normal long-term use. Another way of lubrication is to use the pump to transport the medium for self-lubrication when the pump is clean.
●Use high strength material, pump has good stability
The impeller and shaft of the pump are made of wear-resistant high-strength stainless steel. The pipe and the protective pipe are made of seamless steel pipe or stainless steel pipe with high strength and good stability.
●The pump can operate normally for a long time in a special harsh environment
●The pump is compact, easy to install, debug and maintain.
Long-axis deep well pump operation notes:
1. The pump body bolts must be checked for each shift.
2. Check whether the long shaft deep well pump packing has excessive water leakage. If there is water leakage, add packing or replace it all. (Long shaft deep well pump is in normal state)
3. High-speed motors are prone to heat during operation. When the motor end cover is touched by hand, if it feels too hot for a short time and cannot be touched, the machine should stop running. Cool down and replace another machine.
4. If the motor is in operation, it will sound “bone and bones”, indicating that the bearing is short of oil and must be refueled; if the sound of “stalk” is issued, it means that the inner and outer steel rings or balls are damaged, and should be replaced by stop. More: LC type vertical long axis pump.
5. After a sudden stop or automatic shutdown during operation, the motor will “beep”. This may be due to the lack of phase of the power supply or the main circuit is not completely disconnected. It should be pulled immediately (the main gate is also available), otherwise the motor will be burned and device. After the machine is stopped, the cause must be ascertained, and the operation should be started after the fault is eliminated.
6. The pointer of the water pressure gauge falls during operation, or the pointer of the water pressure gauge does not go. (less than 8kg) At this time, there may be air in the inlet pipe and the pump. If it is found that the rubber short pipe in the inlet pipe has a subsidence phenomenon, it is determined that the inlet pipe filter is blocked, and the machine should be stopped immediately to eliminate the chores on the filter network before starting the operation.
7, pay attention to the sewage well, the water level is too high, must start the sewage pump to eliminate. (stop pump in time)
8. Record the operating machinery and instrument readings and monitor their changes, such as the current meter reading is too high. You must stop the machine to find the cause, and then start the operation after troubleshooting.
9. When operating the air switch and checking the power distribution cabinet, pay attention to safety and avoid electric shock. (preferably power outage check)
10. Do not perform maintenance on the running machine. If maintenance is required, stop the machine first and hang the warning sign.
11. Start the running machinery before eating out of the post. Care must be taken to observe the conditions of water pressure, voltage, current and mechanical operation. If there is no abnormality, you can leave. (Within half an hour) More: TDLC long shaft pump.
12. The staff of the pump factory must do it. They are not late for work, do not leave early after work, do not leave the job in the middle, and have a leave in advance.
13. If the automatic running gear position cannot be started or stopped after a few minutes of running, the automatic signal line may be in poor contact. Must be shut down for maintenance (if not after repair, use the manual button to operate, and replace the automatic line accessories.)
14. The rubber band of the coupling of the pump must be checked every shift, and the problem is found and replaced.
15. Safety of the duty and maintenance personnel of the pump factory: It is necessary to operate the electrical switch without water and moisture on the hand. In order to ensure the safe operation of the pump house, water supply on time, the water pump factory on duty, must be safe to operate. This safety operation procedure is specially formulated.
