Pneumatic mixer is an important machine mainly used in petroleum industry, chemical industry and medical industry. Its function is to stir various materials. The use of pneumatic mixer greatly improves people's work efficiency and facilitates people's production and life. So what are the advantages and disadvantages of tools and accessories such as pneumatic mixers?
1. What are the ways to use the pneumatic mixer?
1. How to use the pneumatic mixer: turn on the lifting switch, put the bucket into the bucket and drop the lifting switch, start stirring and mixing is completed, turn on the lifting switch, take out the bucket
2. Matters needing attention: The matters to be noticed in the cylinder lifting method are: the switch must first rise, stop after, and then fall down to avoid the idling mixer as much as possible. When testing the machine, try to bring materials to test, so as to ensure the balance effect and not hurt When the air horse air motor is used, it must be lubricated.
2. What are the advantages and disadvantages of tools and accessories such as pneumatic mixers?
1. Pneumatic mixer can be adjusted steplessly. As long as the opening of the intake valve or exhaust valve is controlled, that is, the flow of compressed air, the output power and speed of the motor can be adjusted. You can achieve the purpose of adjusting the speed and power.
2. Pneumatic mixer can rotate forward or reverse. As long as the control valve is simply used to change the air motor inlet and exhaust directions, the forward and reverse rotation of the air motor output shaft can be achieved, and instantaneous commutation is possible.
3. The working environment of pneumatic mixer is not affected by vibration, high temperature, electromagnetic, radiation, etc. It is suitable for harsh working environment and can work normally under adverse conditions such as flammable, explosive, high temperature, vibration, humidity, dust, etc.
4. The pneumatic motor supporting the pneumatic mixer has an overload protection function and will not fail due to overload. When overloaded, the air motor only reduces or stops the speed. When the overload is removed, it can immediately resume normal operation, and does not cause damage to the pneumatic motor, such as damage to the mechanical parts. It can run continuously at full load for a long time, and the temperature rise of the air motor is small.
5. Pneumatic mixer has high starting torque and can be started directly with load. Both start and stop are quick and can be started with load. It will not burn the machine and affect the use like the electric mixer.
6. Pneumatic mixer is easy to operate and easy to maintain and repair. The air motor has a simple structure, small size, light weight and high horsepower. Using air as a medium makes it easy to operate and easy to maintain.
3. What is the working principle of pneumatic mixer?
In essence, the stirring process is a single momentum transfer in the fluid field or a process including momentum, heat, mass transfer and chemical reaction, and the agitator is to input mechanical energy to the stirring medium by obtaining a suitable flow field. installation. The stirring process is as follows: the motor drives the stirrer to rotate at a certain speed after changing the speed through the reducer. According to the different stirring speed, the fluid at different speeds is discharged from the impeller. The static flow or low-speed flow is involved, thereby synthesizing a complex motion flow of the air motor. This synthetic motion flow has both horizontal circulation flow and vertical circulation flow along the wall surface and the stirring shaft. This circulation flow can involve a large range in the stirring tank and plays a role of volume circulation. The liquid discharged from the impeller transfers the energy from the impeller to the medium in the tank, and at the same time circulates the liquid in the tank sequentially to the vicinity of the impeller with stirring effect. Due to the instantaneous velocity fluctuations, irregular movements such as turbulence and vortices will gradually disintegrate and mix with the surrounding fluid. As a result, the fluid itself and the heat, mass, and energy contained also move to the surroundings, thereby promoting Mixing, interfacial renewal between phases, etc. cause homogenization of mass flow and heat transfer reactions in the overall flow.
