The reaction kettle is suitable for chemical reactions involving high temperature, high pressure, high vacuum, flammable and explosive media. It is a precision experimental instrument used in many laboratories, universities, and research institutes, and is widely used in laboratories or research institutions. It is also mainly used in fields such as chemical engineering and scientific research. The control of temperature, pressure, and speed inside the reaction vessel is crucial for ensuring product quality and production safety.
What are the key points to pay attention to when installing a reactor? Below, the editor will briefly introduce to you:
1. Reactor controller: The controller should be placed on the operating platform, with a working environment temperature of 10-40 ℃ and a relative humidity of less than 85%. The surrounding medium should not contain conductive dust and corrosive gases.
2. Equipment environment: It should be placed in a high-voltage operating room that meets explosion-proof requirements. When there are multiple devices, they should be placed separately. There should be a sturdy explosion-proof high wall separating the two groups, and each operating room should have an exit or passage leading directly to the outside. When there is an explosive medium, the equipment address and good ventilation should be ensured.
3. Fixed contact inspection: Check whether the moving parts and fixed contacts on the panel and back panel are normal, pull down the upper cover, and check whether the connector contacts are loose, damaged or corroded due to improper transportation and storage.
4. Application of valves: Needle valves use line seals, which can prevent excessive force and damage to the sealing surface by quietly rolling the needle and tightly pressing the cover. This can achieve good sealing effect.
5. Connection of positive and negative nuts: Only positive and negative nuts can rotate correctly at the connection of positive and negative nuts, and the two sides of the circular arc surface must not flip relative to each other. When all threaded joints are installed, oil or oil coordinated graphite should be coated to prevent seizure.
6. Cauldron cover equipment and sealing: The kettle body and kettle cover are sealed with conical and curved surfaces, and the main bolts are tightened to ensure a tight seal and good sealing effect. When tightening the main bolt, the tightening torque should not exceed 80-120nm to avoid compression and overload damage to the sealing surface. The sealing surface should be maintained separately. When installing the pot lid, it should be slowly started up and down to prevent the sealing surface between the pot body and the lid from colliding. The main nut should be tightened symmetrically and gradually multiple times, with even tightening force to achieve good sealing effect.
