1When transporting and installing the kettle body in place, it should be avoided to damage the upper part of the kettle coverReactor magnetic stirrerThe operating room of the reaction kettle requires good ventilation and meets explosion-proof requirements. Install the equipment on the bracket, level it with diagonal iron on the four supports, and keep the equipment perpendicular to the ground. Anti static grounding devices should be installed for equipment with flammable and explosive reaction media to eliminate static hazards.

2Select sealing gaskets that match the reaction vessel medium, design pressure, and design temperature. Sealing gaskets should be installed between the kettle body and kettle cover, magnetic stirrer and kettle cover, and each pipe flange, and the bolts should be tightened again. When tightening bolts, they should be tightened evenly according to the principle of diagonal distribution, and should be divided into sections2~3Tighten the bolt to prevent it from tilting upwards and damaging the sealing gasket, which may affect the sealing effect.

3Add oil tank to the gearbox13Compressor oil or46Mechanical oil should be added to the designated mark and the lubricating oil should be replaced regularly. If the temperature is low in winter, the appropriate mechanical oil should be replaced according to the local actual situation.

4If it is a high-temperature, high-speed magnetic stirrer, lubricating oil should be added to the bearing oil injection port before use. In the future, lubricating oil should be regularly added from the oil injection hole, and the screw plug should be tightened after injection.

5Before turning on the equipment, cooling water should be introduced into the outer water jacket of the magnetic stirrer, with the lower end as the inlet and the upper end as the outlet. A separate cooling water system should be used, and it is not allowed for cooling water to enter the cooling water jacket of the magnetic stirrer through the cooling coil in the kettle. When turning on the stirrer, adjust the water pressure to slightly overflow from the upper outlet of the upper outlet. Do not adjust the water pressure to the maximum to avoid water pressure entering the gearbox inside the reducer due to high water pressure.

In order to ensure the service life of the bearings installed inside the kettle, a cooling water jacket is installed outside the supporting mixing shaft inside the kettle. If the equipment is used at a high temperature, cooling water should be circulated to reduce the temperature, and the inlet and outlet should not be installed upside down.

6The equipment supporting control cabinet and frequency converter should be placed in a separate electrical control workshop that is dry and well ventilated.

7Before starting the mixer, first confirm whether the corresponding mechanical oil has been added to the reducer, then fold down the motor cap, manually rotate the motor fan blades, confirm whether the mixing shaft in the kettle is rotating in the forward direction, and continue to rotate the fan blades until the mixing shaft in the kettle rotates once. During the rotation process, carefully listen for any abnormal sounds inside the magnetic mixer. If there are no abnormalities, then jog the motor and observe the forward and reverse rotation of the mixing shaft in the kettle. If it is a reverse rotation, adjust the motor wiring or adjust the frequency converter.

8The stirring speed of the equipment is greater than80r/minAt this time, the motor should not be started directly at the working speed, and the stirring speed should be slowly increased through a frequency converter. Otherwise, excessive resistance of the agitator may cause overload of the magnetic agitator, resulting in damage to the agitator or burning of the motor.

9After the above work is completed, a sealing test shall be conducted according to the working pressure, and inert gas shall be introduced to maintain pressure15~30Check the overall equipment for leaks in minutes. If there are no leaks, the material can be put into production.

10When using all valves, they should not be closed too forcefully to avoid damaging the sealing surface.

11After feeding, the pressure rise must be carried out slowly. Similarly, the pressure inside the kettle should be gradually reduced.

12Due to the harsh working environment of the reaction vessel, it will seriously affect the service life of the bearings and shaft sleeves. If abnormal friction or vibration sounds occur during normal operation of the equipment, it indicates that the friction clearance between the bearings or shaft sleeves is too large and needs to be replaced immediately.

13. The explosive release device should be tested to ensure its accurate and reliable operation, and the working environment of the equipment should comply with safety technical specifications.

14. During installation, connect the blasting vent directly to the outside through a pipeline!

15. When the kettle is not in use for a long time, the inside and outside of the kettle should be cleaned and wiped clean, and there should be no water or other materials, especially in colder areas where the equipment is not used in winter, all water must be drained.
