This rotation flow formula is one of the types of cartridges. High current speed is created during relatively short running hours, which is an efficient mix in a medium with high non-solsoluble solid content. However, it must be noted that heavier matter may be deposited in the middle of the bottom of the pool.

The depth of liquid in the pool should be between 0.3 and 1 times that of Diameter in the pool.

The diagonal staggered. Avoid short circuits.

If the size of the pool is less than 5-8 times the length of the wheel, the above chart can be used to install it

In larger pools, blenders can be installed as top-map

Consider Outlet

Retrospect the pool wall.

Crosses the current.

Recommended for multiple mixers

Market-like products

1. High development starting point and high level of autonomous intellectual property rights

To improve domestic equipment capacity and replace Inlet, the task is to create independent innovation in the development of a series of products that meet market-specific requirements.

1. Technically backward and highly dysfunctional

Similar products, which are not very innovative, continue to be replicated in the last century using leaf wheel structures, moving structures, guidance coupling structures, sealing structures, etc., and equipment performance is severely lagging behind the requirements of sewage treatment processes, not only without technological advances, but also with high failure rates.

2. Overcoming market failures of the same product and eliminating market failures of the same product

1) to resolve technical difficulties of short-lived, frequent maintenance and replacement;

2) to address technical difficulties of high noise and high vibration;

3) The technical difficulties of unreliability of seals due to the presence of a mechanical seal in sewage;

4) The technical difficulties of the size of the slow-moving vehicle, the weight of the Weight, the length of the axis, and the vulnerability of the moving vehicle to damage were resolved;

5) The technical difficulties of lifting the capacitors are resolved by being inflexible and easily clogged;

6) The technical difficulties of unsettled and loose sub-water installation and condensed land bases, which make underwater maintenance difficult;

7) The technical difficulties of achieving automatic and tight equipment in underwater co-locations are resolved;

(8) The resolution of a range of technical difficulties, such as leaf wheel balance, preservation, geometric error, stress balance, etc.;

9) The technical difficulties of leaking water from the cable feeder seals due to pull;

10. The technical difficulties of re-empowering sewage treatment plants with water installation have been resolved.

2. Disparities persist, with no improvement, and failures remain high and difficult to remove

For many years, the market has had short life expectancy, low-speed institutions that are vulnerable to damage, unstable operations, high noise vibrations, leaks of moving seals, death of ups and downs, inflexibility, poor push-through effects, and high energy consumption.

3. Product characteristics and technological advantages

1) Fiberglass leaf wheels, high-intensity composite materials, integrated formation, strong corrosion resistance, small water resistance, Weight light, high Efficity, high geometrical centre symmetrical and dynamically balanced, first in the country and internationally;

2) Micro-diving lift boxes with compact structures, smoothing, small volume, Weight light, Efficacy high, low failure and long life.

3) an internal cavity lubricating sealing system, which is secure and permanently free from sewage contamination;

4) Base-seat force, which is sustained by the gravity of the equipment from the base, and which is stable in operation, avoiding the shaking and vibrations caused by the traditional conductor force;

5) Bed-bed V-cray condensation, V-cone structure, which enables the equipment to be automatically neutral, stationary and compact; side-side deviation pads to absorb vibrations, and to adapt to the state of the natural adaptation equipment; whole bed-bed layout, like the baby's lying in the cradle, stable and secure;

6) The guidance base support structure, which is both a lifting-oriented body and a stowing-coated bearing support, increases the smoothing stability, supports the simplicity and reliability of the receptivity and resists the impact loads caused by side-directional bias;

7) The cable sets up a tractor protection device consisting of two parts: a auxiliary protection unit in the underwater entry seal to protect the entry seal from being pulled out; and a waterproof cable removal unit to protect the cable from falling and frowning;

8) A modular card-deficit slider to upgrade the institutional design set-positioned double-axis dust-proofer to ensure that the wheel itself is flexible and does not cause a gravitational friction of two-sided support; and that the moderate mobile slider group is designed on the tail of the equipment so that it does not have a self-locking phenomenon with the track to ensure smooth slide;

9) Water-laying installation, first created in the country and abroad, developed at the request of market users, and directly fitted to water.

10. Help users to select science and rationalize their configuration to Power;

11. General and excellent configurations, appropriate to user needs

3. Status of technology for the same product

1) Conventional material wheels, or Weight large, or resistant to corrosion, or rigidity, disfigured or less resilient leaves, are vulnerable to uneven shocks. In particular, blades are combined with rotor rims, threaded, not only complex and large, but also with great difficulty in ensuring the geometry of the two leaf centres, making it more difficult to ensure that the threads of long-term work are not loose. Moreover, the leaves are made in a wide range of shapes, many unsound designs and scientific arguments, and are used to a high degree by poor hydrodynamic properties, low push-flowing capacity and high energy;

2) General deceleration Rotation Agency, which is not sufficiently capable of adapting to the dive conditions and is not structured in a sufficiently large and dispersed manner to allow for low-motion Efficity, high failure rate and short life;

3) the mechanical sealing of open sewage lubricants, which are de-scalated by sewage and are exposed to the water force, fibres, and suspended particles and damage;

4) A conductor bearing structure, which is supported by underwater guidance, long guidance, medium and lower stress, and rigidity, which can easily form a shake and vibration.

5) Underwater co-opts use tablet or stool-type stools, which do not allow for automatic fixation and tightening of the equipment, and the vibration is inevitable. The equipment operates on a tablet or stool-type stool, with a stabilizing effect that is far removed from the bed-bed V-cone suction convection.

6) A cable-free tractor protection device, with no aided protection in the seal of cable-line entry, which can affect the sealing effect by pulling.

7) The lifting of the slide combination and the flow path to self-lock and carcass, affecting the ease and flexibility of operation.
