Where there is no clean water or where the cost of clean water is high, a special structure can be added, and the guide bearing can be cooled and lubricated by the medium pumped through filtration or precipitation separation. Check the impeller of vertical axial flow pump whether there are cracks or holes, whether the impeller nut is loose, if damaged should be repaired or replaced. If the impeller is worn too much or has been damaged, new impeller should normally be replaced. Local damage can be welded or repaired with epoxy resin mortar impeller, after the repair of the impeller should generally be static balance test. Check the clearance of impeller wear ring, if it exceeds the specified value, repair or replace it. The major axis
The motor adopts triple sealing structure, which solves the problem of water leakage of submersible motor, improves the market competitiveness and wins more market for submersible axial flow pump. The motor is equipped with leak detection and temperature measuring device, which improves the safety and reliability of submersible axial flow pump, and ensures that the motor will not be burned out because of leakage and overheating. The unloaded screws are soaked in diesel oil and cleaned with steel wire brush, coated with oil or butter, re-installed or wrapped in plastic cloth and put away (also can be soaked in diesel oil to save), so as not to rust or lose.
Lubricating water system is equipped with flow and pressure relays and other control elements. When the water supply before starting is lower than the rated water supply, the pump can not start. When the water is short due to some reason (pipeline blockage), the relay sends an alarm signal, the buzzer in the control room sounds, the red light alarms, and then the bypass can be turned on. The system's valve water supply, to ensure adequate water supply, while the fault can be repaired, this control system can achieve remote control.
After the vertical axial flow pump is shut down, the remaining water in the pump and pipeline should be drained out, and the external soil should be cleaned, so as to avoid the pump body and water pipe cracking after freezing. Belt-driven, belts unloaded with warm water after cleaning and drying hanging in dry, no direct sunlight, also do not store in the oil, corrosion and smoke place. Under no circumstances should belts be stained with oils such as engine oil, diesel or gasoline, or with rosin or other sticky substances.

Previous:What if we do not dismantle the straight optical axis according to the specifications?
Next:Linear optical axis is one of the necessary devices to realize linear motion, and we have more chances to contact this kind of products in our daily work.
