Submerged flow mixer MA0.85/8-260/3-740/S

Submerged flow mixer MA0.85/8-260/3-740/S

The MA0.85/8-260/3-740/S underwater push flow mixer system mainly consists of a pressurization system, a water supply system, a pressurization and constant pressure system, a nozzle pipeline system, a CNC worktable system, a water collection system, and a water circulation treatment system. If it is an abrasive jet machining device, there is also a mixing system of abrasive and water.

Application of submersible mixer:

1. Cutting and processing:

The application of submersible mixer technology in cutting is, in a sense, a revolution in the cutting field. With the maturity of technology and the overcoming of certain limitations, submersible mixer cutting is a perfect supplement to other cutting processes.

There are many types of materials processed by submersible mixers, mainly non-metallic or metallic materials that are difficult or impossible to process by general cutting methods, especially for the processing of some new and synthetic materials.

2. Deburring:

The removal of burrs such as cross holes, internal threads, narrow grooves, blind holes, etc. on various small precision parts is very difficult or even impossible to complete using other general processing methods. However, the use of submersible mixer processing technology is very convenient and of good quality, with unique effects.

3. Punching:

Submersible mixers can be used to drill holes on various materials instead of drill bits, not only with good quality, but also with fast processing speed.

The characteristics of the submersible mixer processing are that it does not generate heat and does not damage the material of the workpiece. It is used to clean the back of the welded joints of heat sensitive metals and remove defects such as cracks in the weld seam.

MA0.85/8-260/3-740/S Submersible Mixer Usage and Applicable Conditions

Suitable for aeration tanks and anaerobic tanks in industrial and urban sewage treatment plants, it can be used to create water flow during water circulation, nitrification, denitrification, and phosphorus removal stages.

The mixed mixing series products use multi pole motors and adopt a direct connection structure, which has low energy consumption and high efficiency; The impeller is formed by precision casting or stamping, with high precision, large thrust, beautiful and smooth appearance, and compact structure.

The low-speed thrust series products adopt cycloidal pinwheel reducers, equipped with low power, low speed, large impeller diameter, and wide service area. The impeller is made of polyurethane material and aluminum alloy, with high strength and strong corrosion resistance. In addition to its stirring function, it also has the functions of pushing and creating water flow.

The motor winding of the submersible mixer is F-class insulated and has a protection level of IP68. When used in conjunction with the aeration system in sewage treatment plants, it can greatly reduce energy consumption and significantly increase oxygen filling, effectively preventing sedimentation. According to the process requirements, the direct coupled submersible mixer can be equipped with a guide cover.

The mixing and stirring series submersible mixer is suitable for various water treatment processes and industrial processes that require uniform mixing and reaction of solid and liquid two-phase or solid, liquid, and gas three-phase media.

The submersible mixer series products use multi-stage motors, and the motor winding of the submersible mixer is F-class insulated with a protection level of IP68.

1. Performance of submersible mixer motor malfunction: Before disassembling the motor, we conducted an idle run to identify the problem. Unexpectedly, the motor made abnormal noise and experienced significant vibration; The submersible mixer emits a hissing sound at the shaft sleeve of the motor shaft, as if a certain component is "spinning" and cannot synchronize; The shaft extension temperature of the motor reaches over 60 degrees Celsius in less than 2 minutes of idle operation, giving a hot feeling.

2. Structural diagram of submersible mixer: The following figure is the assembly diagram of the impeller pump side bearing, with the bearing model being SKF

6309. The outer ring of the bearing is positioned with retaining ring 5, and the inner ring is positioned with shaft sleeve 4. The submersible mixer is fixed with spring retaining rings 2 and 3; The specification of skeleton oil seal 11 is 55x80x8, installed between retaining ring 5 and shaft sleeve 4, and slides on shaft sleeve 4; The fixing of the other end of the bearing relies on the shoulder of the 45 shaft section and the step of the bearing seat; The fit between the 55 shaft segment and the bearing seat is H8/f7, which is equivalent to a sliding bearing; The helical gear 7 is embedded in the right end of the submersible mixer shaft 8 through interference fit; 1 is the oil slinger, which prevents the oil from the gearbox from entering the skeleton oil seal.
