QJB Series Submersible Mixer

Quantity:

Introduction

QJB type Submersible Mixer, a key equipment used in the water treatment technology, can meet the technological requirement for homogeneity and fluidity of solid-liquid two-phase flow and solid-liquid-gas three phase flow in biochemical course of the water treatment process. It is composed of the submersible motor, impeller, and installation system etc.. The submersible mixer is in direct connection structure. Comparing with the traditional high-power electric motor that retards speed by a speed reducer, it is highlighted by compact structure, low energy consumption, facile maintenance. The impeller shaped by finishing casting or punching, which has high precision, forceful thrust as well as simple, nice-looking and streamlined profiling. The series of products are applicable to the places that requires for solid- liquid agitating or mixing. 


Use Conditions

QJB type multi-functional swirling submersible mixer in the following conditions can be normal run continuously

l.the highest temperature of the medium no more than 40℃;

2.medium PH value in between five to nine;

3.medium density of not more than 1150 kg/m³;

4.the long-term diving operation, diving depth in general not more than 20 m.


Characteristics

1.QJB type multi-functional spin in streaming submersible mixer compact structure, small volume, light weight, easy operation and Maintenance, easy installation and maintenance and long service life.

2.Impeller water conservancy has the best design structure, high efficiency, sweptback blade with consecrated the mselves function can prevent sundry winding, jam.

3.and aeration system can be used together to reduce energy consumption, oxygen filling improved obviously, effectively prevent Precipitation.

4.unique cable seal design, ruled out cable slack hidden trouble.

5.motor winding for class F insulation, protection grade for IP68, choose a lubrication free maintenance high quality bearing, has the Oil leak detection room and motor winding overheating protection function, make electricity Machine work more safety and reliable.

6.Two way independent mechanical seal, mechanical seal of the friction material for corrosion resistance of pay and tungsten carbide. All fasteners for stainless steel material .

7.Standard components are electrolytic separation technology, which can help to prevent corrosion.


Structure Introduction

QJB type multi-functional swirling submersible mixer mainly by the equipment installation and the electric control system, the host of equipment.

QJB type multi-functional swirling submersible mixer according to their function forms can be divided into mixed submersible mixer and low speed push flow pattern submersible mixer. Mixed according to the structure characteristics of submersible mixer and points For straight league stamping type and the submersible mixer straight association-like submersible mixer. Low speed push flow pattern is a submersible mixer straight association-like submersible mixer.

Mix series QJB type multi-functional swirling submersible mixer blade way according to the forming and divided into casting mixer and stamping mixer. Casting mixer blade (impeller) for casting process, machine Body shell material generally for cast iron. Stamping mixer blade for stamping, The body shell material for stainless steel.

Straight league stamping type structure of the submersible mixer multipole motor, the hydraulic parts stamping forming, good accuracy, high efficiency, impeller blades have different Angle. The hydraulic balance No blocked after pulling design, compact structure, small volume, light weight, easy operation and maintenance, installation is convenient and fast, long service life. Cases all adopt the stainless steel manufacturing, appearance beautiful View fluent. Approved by the national environmental protection bureau that, ate home and abroad in the submersible mixer is first selection product.

Mixed submersible mixer made to increase the general diversion cover axial flow and reduce the radial flow, reduce vibration, increase operation of the impeller smoothness. And low speed push flow pattern submersible mixer not preparation Diversion hood.

As shown in figure 1 shows, the straight association-like submersible mixer mainly by the impeller, submersible motors two main components, directly into the motor shaft impeller.
