Precautions for the use of explosion-proof single fluid refrigeration heating temperature control de
There are many types of reactors, and laboratory reactors are one of them. What is the point of attention of LNEYA reactor temperature control system-explosion-proof single-fluid refrigeration heating temperature control device?
The temperature measuring device, as the name suggests, is a device for measuring the internal temperature of the reactor. The temperature range is from -120°C to 350°C. It uses a magnetic drive pump and high temperature cooling technology. It can directly cool down from 300°C because only the heat conduction in the expansion cavity The medium only comes into contact with oxygen in the air (and the temperature of the expansion tank is between normal temperature and 60°C), which can reduce the risk of heat transfer medium being oxidized and absorbing moisture in the air.
Explosion-proof single-fluid refrigeration, heating and temperature control device supporting the reactor should pay attention to excessive heating or rapid cooling during the working process to prevent excessive temperature changes from causing cracks in the reactor body. If the reactor supporting the single-fluid refrigeration, heating and temperature control device is equipped with a magnetic stirrer, when the temperature reaches 100 degrees or more during the reaction, cooling water must be introduced into the stirrer to avoid excessive temperature damage to the stirrer.
After the reaction kettle of the explosion-proof single-fluid refrigeration heating and temperature control device is completed, the reactor is cooled down first, and then the high-pressure gas in the laboratory reactor is released to reduce the pressure to normal pressure, and then the main bolts are symmetrically and evenly loosened.
When the reactor supporting the explosion-proof single-fluid refrigeration heating temperature control device heats up slowly, when the reactor supporting the explosion-proof single-fluid refrigeration heating temperature control device operates, strictly avoid the metal or block hard objects falling into the stainless steel reactor. Prevent damage to the tank wall; make the stirring operation after turning on the power, and observe whether the transmission parts such as the reducer and stirring are abnormal.
The pressure and temperature rise and fall of the jacket or inner tank of the explosion-proof single-fluid refrigeration, heating and temperature control device must be slow to prevent the stainless steel reaction kettle from being impacted by cold and heat, resulting in bulging of the inner wall, and it is strictly forbidden to approach or exceed the equipment's high allowable The working pressure is prohibited to approach or exceed the high allowable working temperature of the equipment.
There are many manufacturers of explosion-proof single-fluid refrigeration, heating and temperature control devices, and users must be cautious when choosing.
February 6, 2021If you need equipment to distill CBD, you need to scrutinize your choices, as the equipment can vary in its features and design. When you use equipment that produces a CBD distillate, you want to seek out a system made by a manufacturer that provides proven and reliable products. You should also work with a business that can train you on the use of the equipment you buy.view
