The wear and tear between the three pairs of friction pairs (hydrostatic bearing relationship) in the relative motion of the deep well long shaft pump in operation makes the gap between the parts enlarged, the leakage of the deep well long shaft pump increases, and the oil temperature rises correspondingly. The soft life of pump is from initial running-in period to stable service period and then to fatigue spalling period (severe wear stage). The length of the three stages depends mainly on the cleanliness of the liquid medium used. Another decisive factor affecting the soft life of deep well long shaft pump is the bearing life of deep well long shaft pump.
Long shaft submerged pump is a motor and centrifugal pump together into the bottom of the oil tank, driven impeller to pressurize the oil, the oil will be pushed to the target storage, compared with other structures, start without self-priming, oil separator on the surface of the oil, so as to solve the shaft is too long, different center problem, theoretically the shaft can be unlimited lengthening.
The water flowing from the suction pool passes through the suction horn tube, because the impeller blades in the impeller chamber force the water to rotate, so that the water enters the guide vane body, and the energy transfer occurs in the head, which flows through the pump cylinder body and is discharged from the drainage bend. The pump is combined with the central shaft through the coupling (rigid). The bearing below the motor supports the downward axial force of the rotor. The central shaft is combined with the motor shaft with an elastic coupling.
The long shaft submerged pump adopts a unique single blade or double blade impeller structure, which greatly improves the dirt transport capacity. It can pass through 5 times the diameter of the pump and about 50% of the diameter of the pump solid particles. The mechanical seal of the submerged sewage pump adopts a new type of hard seal. The tungsten carbide material with high quality and corrosion resistance, and the seal is improved to double face seal, so that it can run in oil chamber for a long time, so that the pump can run safely and continuously.
