structural characteristics

The QJB-P submersible jet aerator consists of a submersible motor, a hard toothed reducer, a wide propeller blade, a well pump impeller, a space guide vane, an intake pipe, a muffler, an installation float, and an electronic control.

Submersible motor: three-phase squirrel cage induction motor, installed in an inflatable waterproof casing, with stator insulation level of H (180 ℃), protection level of IP68, vacuum impregnation, direct cooling of working medium, power supply of 380V/3-phase/50HZ;

Main shaft: The rotor shaft and the output shaft of the impeller are both made of stainless steel ASTM420 (2Cr13), which has sufficient strength;

Bearings: The main bearings of the submersible motor are double row angular contact, the supporting bearings are deep groove balls, and the reducer bearings are in the form of automatic self-aligning rollers and deep groove balls. The whole machine has eight imported bearings, which can withstand the radial and axial loads caused by the three-phase flow of solid, liquid, and gas.

Shaft seal: It adopts independent three series connected rubber corrugated tube mechanical seals, and the friction pair material is tungsten carbide tungsten carbide;

Impeller: The impeller of the propeller adopts a swept back anti winding airfoil and is made of glass reinforced polyurethane material; The impeller of the self-priming aeration device adopts a patented design of a large channel well pump, with auxiliary three-dimensional guide vanes for high efficiency and large air intake;

Sealed cable: The cable sealing head is sealed by special vulcanization treatment or by pouring environmentally friendly resin as required;

Motor protection: The motor has overload and overheating protection, and three sets of thermal switches are embedded in the winding coil;

Hard tooth helical gear: professionally customized submersible gears can efficiently transmit torque and operate stably and reliably;

Motor hanger: Made of stainless steel, it can avoid any electrochemical corrosion, is easy to lift, and runs stably;

Leakage sensor: using electrode type copper rod, with sensitive and reliable response, to prevent the submersible motor from leaking and burning.

Anti corrosion: The shell adopts marine anti-corrosion coating, which can be used in sewage medium for a long time.

Advantages

1. It is designed with patented technology, with high hydraulic efficiency, large air intake, high oxygen charging efficiency, small power of single unit, obvious energy-saving effect, and wide service range, which is very suitable for natural Rivers and Lakes treatment;

2. There are few operating attachments, and as long as the power is turned on, aeration and flow pushing can be carried out simultaneously, abandoning the traditional dual speed motor design of products - one motor with different speed and power is responsible for flow pushing and stirring, while the other motor with different speed and power is responsible for aeration, which means that aeration cannot be carried out during agitation and flow pushing;

3. Wide range of application technology, due to the use of large propeller blades and low-speed airfoil design, the thrust working components generate transverse tangential water flow, which is uniform and not chaotic, with high efficiency, low loss, long thrust distance, and large jet suction area, ensuring that the water body always maintains a spiral circulation motion. Suitable for water restoration, ecological engineering, and various biochemical treatment stages such as anaerobic, aerobic, and facultative.
