What are the precautions when using a large agitator?

The use environment, whether the stirring material is corrosive, whether the rated power voltage meets the requirements, safety, etc., need to be paid attention to.

Everyone should have a certain understanding of the application of side-entry agitator, after all, side-entry agitator is not a novel equipment now, and it is used in many industries. However, there are not many users who can fully explain the working principle of the side-entry mixer, and everyone pays more attention to its operation when using it. Stirring can cause two or more different substances to be dispersed among each other.

There are two types of paddle agitators: flat paddle type and oblique paddle type. The flat paddle agitator consists of two straight paddle blades. The ratio of the diameter of the propeller to the height is 4 10 and the circumferential velocity is , resulting in a smaller radial flow velocity.

The two blades of the slobly paddle agitator are reversed by 45° or 60°, resulting in an axial flow. Paddle agitators are simple in structure and are often used for the mixing of low-viscosity liquids and the dissolution and suspension of solid particles.

As for the large agitator, I think it will be fine to follow the instructions for use. In fact, no, if you want to get a good use effect, it is best to master some skills when using the mixer, so as to avoid many problems and failures, and make the mixer work better.

Assembly and disassembly of the mechanical seal of the mixer: The assembly must be carried out in very clean environmental conditions and the assembly medium is pure lubricating oil. First of all, all parts of the mechanical seal must be cleaned, and then the static ring device of the mechanical seal at both ends is evenly and smoothly pressed into the positioning hole, pay attention to protect the static ring sealing surface, and must not damage the sealing surface, and then use the guide sleeve to load the moving ring into the shaft, close the end cover of the oil chamber, pay attention not to collide with the sealing surface of the mechanical seal, and the disassembly of the mechanical seal can be carried out in reverse order above.

Mixers are mainly used in anaerobic tanks, anoxic tanks, conditioning tanks, selection tanks and sludge tanks in sewage treatment plants. After the mixer is put into operation, regular maintenance and maintenance can better play its role.

Choosing a first-class blender is very important, related to daily use? What are the precautions for choosing a blender? PChouse will take you to find out.

First, pay attention to the power of the blender. If you need to stir some hard food, such as ice cubes, you need to add it to the juice and stir it together, then it is recommended to choose a high-power blender as much as possible, the power of high-power mixing will be stronger and more powerful, and it will be easier and less laborious to stir hard food. Therefore, it is recommended that it is best to choose a mixer with a power of more than 700w, which will be more powerful.

Second, look at the blender's blades. Looking at the blade of the mixer, it is an important small detail to buy a mixer, whether the blender crushes well or not, all on the blade. Therefore, it is recommended to choose a blender with 4 or more blades than 5 petals as much as possible, so that the mixing force is large, and the crushing effect will be better.

Finally, pay attention to the speed of the blender. If you like to drink a variety of fruit juice drinks, then it is recommended to choose a blender with adjustable speed as much as possible, so that you can freely adjust the speed of the blender, and some fruit juice drinks do not need to be stirred too much to taste better. Therefore, you can choose a mixer with a speed control function.

When it comes to electric mixers, most people may ask: what is an electric mixer? What are its features?

How does it work? It's not surprising that electric mixers are used in areas that are usually difficult to access, and are operated by specialized technicians. However, I will introduce you to the role of electric mixers and some points to note when using them.

I hope that through my explanation, you can have a general idea of it.

First, the role of the electric mixer:

The electric stirrer is suitable for biological, physical and chemical, cosmetics, health care products, food, reagents and other experimental fields. It is an experimental equipment for liquid mixing and stirring. The product concept has novel design, advanced manufacturing technology, large torque output for low-speed operation, and good continuous use performance.

The drive motor adopts a series excitation micro motor with high power and compact structure, which is safe and reliable in operation; The operation state control adopts CNC touch type stepless governor, which is convenient for speed regulation; The digital display of the running speed status is correct, and the collected data is correct; The output force booster mechanism adopts multi-stage non-metallic gears to transmit force increase, the torque is simply multiplied, the operating state is stable, and the noise is low; The special rolling head for the stirring rod has the characteristics of easy and flexible unloading and installation. It is an ideal equipment for factories, scientific research institutions, colleges and universities, and medical units for scientific research, product development, quality control and production applications.

The general magnetic stirrer has two functions: stirring and heating. Specifically: the first function is to mix the reactants evenly and make the temperature uniform, the second is to heat in a closed container, which needs to prevent overboiling, for example, in the distillation process, you can add zeolite, you can also use a magnetic stirrer, and the third function is to speed up the reaction speed, or evaporation rate, shorten the time.

2. Precautions for use:

1. Be sure to connect the ground wire when using.

2. If you find that the stirring rod is not concentric and the stirring is unstable during work, please turn off the power supply and adjust the support chuck to make the stirring rod concentric.

3. Medium-speed stirring can reduce vibration and prolong service life.

4. The instrument should be kept dry.

5. Ambient temperature: 0-50, no corrosive gas.

6. Relative humidity: 35%-85% (no condensation).

7.Do not overload.

8. In order to ensure the safe use, please use the grounding wire.

9. Fuse tube 5 20 15a.

10. When not in use for a long time, please store it in a dry and non-corrosive gas place.

The above summarized information is some basic knowledge related to electric mixers. Through the above text explanation, do you already have a general understanding of electric mixers? Although the electric mixer is difficult to come into contact with in our daily life, and we don't need to know so much about it, but the knowledge will become our own, whether it will be used in the future or not, it will not be too much to learn a little more and understand a little more.

1. The mixer should be set in a flat position, and the front and rear axles should be padded with square wood, so that the tires can be raised and overhead, so as to avoid walking when driving.

2. The mixer should implement two-level leakage protection, and after the power supply is turned on before going to work, it must be carefully inspected, and it can be used only after the empty car test transfer is qualified. During the trial operation, the speed of the mixing drum should be checked whether it is appropriate, under normal circumstances, the empty speed is slightly faster than the heavy car (after loading) 2 3 turns, if the difference is more, the ratio of the moving wheel and the transmission wheel should be adjusted.

3. The rotation direction of the mixing drum should be in line with the direction indicated by the arrow, if it does not match the truth, the motor wiring should be corrected.

4. Check whether the transmission clutch and brake are flexible and reliable, whether the wire rope is damaged, whether the track pulley is good, and whether there are obstacles around and the lubrication of various parts.

5. After starting the machine, always pay attention to whether the operation of each part of the mixer is normal. When the machine is stopped, always check whether the blades of the mixer are bent and whether the screws have fallen off or loosened.

6. When the concrete is mixed or is expected to stop for more than 1 hour, in addition to the remaining materials are cleaned, stones and water should be poured into the shaker, the machine should be turned on, and the mortar stuck to the barrel should be washed clean and all discharged. There should be no stagnant water in the barrel to avoid rust on the barrel and blades. At the same time, the dust accumulation outside the mixing drum should be cleaned to keep the machinery clean and intact.

7. After work and when the shutdown is not in use, the power should be turned off and the switch box should be locked to ensure safety.
