The working temperature of electric drum is relatively high. The demand for chemical lining fabric is usually carried out at a certain temperature, so the reaction tank is not only pressure resistant but also temperature resistant. This requires the application of refined methods. Below, the editor will briefly introduce the blasting method of electric drum.
1. Electric cannon refining: Wrap the internal resistance wire of the electric drum around the insulation layer of the reaction tank body, or install it on a special insulator far away from the reaction tank. Therefore, a small spatial gap is formed between the internal resistance wire and the reaction tank.
2. Steam refining: When the refining temperature is below 100 ℃, a steam with a pressure below the majestic pressure can be used for refining; Use full steam within the range of 100~180 ℃. When the air temperature is high, high-pressure superheated steam can be used.
3. Heating: It can be used when the temperature is not high, and there are two types of refining systems: open and closed. The open type is relatively simple, consisting of a circulation pump, a water tank, pipelines, and a regulator for operating valves. When using high-pressure water, it is required that the electric drum has high strength, the outer layer of the reaction tank is welded with a serpentine tube, and there is a gap between it and the kettle wall to increase thermal resistance and reduce heat transfer efficiency.
4. Refining with other media: It is processed by other media, and if high-temperature operation is required for processing, or if the high-pressure processing system is exempted, it can use other media instead of water and steam. Such as mineral oil production (275-300 ℃), diphenyl ether mixture (boiling point 258 ℃), molten salt (140-540 ℃), liquid lead (melting point 327 ℃), etc.
After understanding the firing method of electric drum, it can help us effectively ensure its quality in the following production work, thereby reducing the occurrence of faults. We hope that the content described in this article will be helpful for everyone's operation and use. In the future operation and use, we will pay more attention to this requirement.
The electric drum is mainly composed of a motor and a reducer, which are placed inside the drum as a whole. There is also a drum body inside, which is used to support the transmission belt and make it move. It is necessary to connect the end cover, pressure cover, bearings and other components to the drum body itself, and use brackets and front and rear shafts to support the equipment as a whole. Undoubtedly, components such as motors and transmission mechanisms constitute an indispensable part of drum equipment.
The electric drum works very well and has good effects in many aspects. However, when people use a device, they cannot solely focus on that device for production. The premise is to understand the structure of such equipment and fully utilize its functions and effects to avoid equipment production failures, without knowing how to solve them.
The above is the blasting method of electric drum. It is a new type of driving device that combines a motor and a reducer in a drum. It is mainly used for fixed and mobiles belt conveyors, replacing traditional motors.
