1.實驗室嚴禁煙火并需配備滅火設備。
Fire is strictly prohibited in the laboratory and fire-fighting equipment must be provided.
In case flammable and explosive gas is produced during the test, all electrical appliances in the laboratory must be explosion-proof. The test staff shall not wear leather shoes with nails in order to prevent sparks. Rubber or cloth shoes are recommended.
3.請仔細了解用戶應承擔的義務和責任。
Please fully understand the obligations and responsibilities of users.
Any test staff using high pressure reactor can only operate after reading this manual carefully and shall not leave without permission during the test. Closely monitor the temperature and pressure changes during the operation so as to prevent the accident by means of power cut and pressure relief in time before the occurrence of over temperature or overpressure. Please note that if the temperature is within 100 ℃, the pressure in the reactor is close to one atmospheric pressure. After 100 ℃ or above is reached, the pressure will rise slowly. The pressure in the reactor is a cubic function of the temperature. After it reaches 200 ℃ or above, the pressure will rise very quickly. If no one is available, it is very easy to cause the accident.
The user is willing to add pressurized gas into the reactor, it is recommended to raise the pressure after heating. However, the pressure of the air pressure source shall exceed the pressure in the reactor; otherwise the pressure in the reactor will recoil at the air pressure source. In order to avoid recoil, it is recommended to add a one-way valve in the supply line. If the user wants to heat up after pressurization, it shall be considered that the pressure of this part of gas will be multiplied during the heating, and it may rise 10 times at 300℃. In addition, the saturated vapor pressure in the reactor can easily cause overpressure. If no one is available at this time, it is easy to cause the overpressure accident.
Neither the max. working temperature nor the max. working pressure of the reactor shall not exceed the value specified in the contract. The user has the responsibility to carry out the research on the temperature, pressure, physical and chemical properties of the chemical reaction system so as to ensure that the selected reaction conditions are within the safe operating conditions of the purchased reactor.
User shall select the correct working medium and the nature of chemical reaction during the test, make sure not to damage the equipment or cause personal injury. Yansheng is not responsible for that, because it does not know what test the user is going to do. If corrosive media are to be used, the user must provide corrosion-proof reactor. It is forbidden to use explosive medium or choose the chemical test with explosive reaction. Please note that in case of explosive reaction, the reactor will be damaged before the rupture disk bursts in time.
Please note that the maximum working pressure shall be less than 70% of the burst pressure of the rupture disk, not greater than or equal to the burst pressure of the rupture disk. Yanzheng selects the burst pressure according to the working pressure required by the user. When the pressure of the reactor exceeds such working pressure, the rupture disk will burst.

10.在開始使用高壓容器前必需考慮到以下問題:
User must consider the following questions before using the high pressure reactor:
Is the chemical reaction you are doing in is exothermic? If a large amount of heat is generated during the reaction, the pressure in the reactor will be suddenly and violently increased to damage the reactor.
你從事的化學反應會有什么副產品產生?它們有什么特性(易燃,易爆,有毒等等)?
What by-products will be produced during the reaction? What are their characteristics (flammable, explosive, toxic, etc)?
過程中會產生多大的溫度和壓力?
What is the maximum temperature and pressure produced during the reaction?
你從事的化學反應在什么條件下(什么樣的溫度,壓力,催化劑作用下)會產生失控現象?
Under what conditions (temperature, pressure or catalyst) will the chemical reaction be out of control?
Special care must be taken to deal with highly active compounds such as acetylene, butadiene, dioxane, ethylene oxide, oxygen and other strong oxidants.
對任何會突然釋放大量熱量的試驗,對會產生爆炸性副產品或終產品的試驗也要特別小心。
Special care must be taken for any test that will suddenly release a large amount of heat and which may produce explosive by-products/final products.
If you use new or unclear materials for the test, it is recommended to conduct the preliminary test with a small amount of reagent to understand their properties and possible problems during the test.
The laboratory must be well ventilated and the reactor shall be placed near the exhaust hood or air outlet. When necessary, especially when it is possible to produce flammable or toxic gas, more ventilation devices shall be provided to remove the gas outside. If necessary, the protective wall shall be used to ensure the safety of the test. Please note that reinforced cement, rather than glass or reinforced glass, shall be used for the protective wall.
The laboratory shall not be close to the top of the reactor, because a large amount of superheated steam, flammable or toxic gas will be released when the rupture disk bursts, which will also produce huge noise to harm human body and damage hearing. In that case, the outlet of the rupture disk shall be connected to the outdoor or take measures to protect the eardrum.
If flammable and explosive gas is produced during the test, explosion-proof measures must be taken for all electrical appliances. The explosion-proof main switch shall be placed outdoors.
Generally, the amount of test materials shall not exceed 2/3 of the reactor volume, because some media (e.g. water) will expand more than three times at high temperature to suddenly raise the pressure and exceed the permitted pressure limit. It is recommended to carry out the test with a small amount.
It is recommended not to use the maximum working temperature/pressure for the test, because the temperature and pressure of the reactor will further increase to an unacceptable level due to chemical reaction.
16.不要用砂紙打磨、清理容器。這會降低容器的承壓能力。
Do not use sandpaper to polish or clean the reactor as it will reduce the pressure bearing capacity of the reactor.
It is necessary to tighten the sealing nuts of the reactor evenly and gradually with the specified torque, so that all bolts bear the same stress. Do not tighten some nuts at first and then others. In that case, the stress of the bolts tightened first will be much higher than that of others. It will cause deformation of the thread. Do not over tighten or loosen the nuts. Too loose will lead to insufficient sealing pressure and leakage while over tightening will overload or damage the bolts.
When new reactor is used, the distilled water (50%) can be heated to 150℃ to check the sealing of the reactor and the operation of each control system.
19.實驗前,檢查墊圈的狀態,如損壞,需及時更換;如發現起了毛邊,用小刀輕輕刮去。
Check the washer before the test. Replace in time if it is damaged. If burr occurs, remove it gently with a knife.
