 產(chǎn)品經(jīng)第三方機(jī)構(gòu)測(cè)試,抗干擾性能符合工業(yè)條件下電磁兼容的要求。

The product has been tested by the third party agency and its anti-interference performance meets the electromagnetic compatibility requirements under industrial conditions.

 

 1.實(shí)驗(yàn)室嚴(yán)禁煙火并需配備滅火設(shè)備。

Fire is strictly prohibited in the laboratory and fire-fighting equipment must be provided.

 2.實(shí)驗(yàn)過程中若有易燃易爆氣體產(chǎn)生,實(shí)驗(yàn)室中所有電器必須是防爆的,實(shí)驗(yàn)工作人員不可穿帶釘皮鞋,以防止打火花,建議穿膠鞋或布鞋。

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(qǐng)仔細(xì)了解用戶應(yīng)承擔(dān)的義務(wù)和責(zé)任。

Please fully understand the obligations and responsibilities of users.

 4.任何使用高壓反應(yīng)釜的實(shí)驗(yàn)人員,需在仔細(xì)閱讀使用手冊(cè)后,方可允許上崗位操作,并在實(shí)驗(yàn)過程中,不得擅自離崗。應(yīng)嚴(yán)密監(jiān)視操作過程中的溫度和壓力變化,以便在發(fā)生超 溫或超壓情況之前,及時(shí)采取斷電和卸壓等應(yīng)急措施,防止事故發(fā)生。注意溫度在攝氏100度之內(nèi),容器內(nèi)的壓力接近 一個(gè)大氣壓,攝氏100以后開始?jí)毫ι仙^慢,但此時(shí)容器的壓力為溫度的3次方函數(shù),到攝氏200度以后,壓力上升會(huì)非常快,若無人值守,極易造成事故。

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.

 5.若果用戶要在容器中加入有壓力的氣體,建議先加溫,后加壓。但氣壓源的壓力應(yīng)超過此時(shí)容器中的壓力,否則容器中的壓力會(huì)反沖向氣壓源,為避免反沖發(fā)生,建議充氣 管路中加一個(gè)單向閥,如果用戶要先加壓后加溫,則應(yīng)考慮到在加溫時(shí)這部分氣體的壓力會(huì)成倍上升,在攝氏300度時(shí)有可能上升10倍。再加上容器內(nèi)液體的飽和蒸汽壓,極易 造成容器超壓。此時(shí)若無人值守,極易造成超壓事故。

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.

 

6.容器的工作溫度和工作壓力中任何一項(xiàng)都不得超過合同上規(guī)定的指標(biāo)。用戶有責(zé)任對(duì)其將進(jìn)行的化學(xué)反應(yīng)體系的溫度、壓力、物理和化學(xué)性質(zhì)進(jìn)行全面的調(diào)研,以保證所選擇的反應(yīng)條件是在購(gòu)置的反應(yīng)釜的安全限定操作條件內(nèi)。

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

 7.用戶有責(zé)任正確選擇工作介質(zhì)和試驗(yàn)過程中化學(xué)反應(yīng)的性質(zhì),保證不損壞設(shè)備或造成人身事故,巖征對(duì)此不負(fù)任何責(zé)任,因?yàn)樗麄儾⒉恢烙脩粢鍪裁丛囼?yàn)。如果要使用腐蝕性介質(zhì),用戶必需能抗腐蝕的供應(yīng)容器。嚴(yán)禁使用具有爆炸性的試驗(yàn)介質(zhì)或選擇具有爆炸反應(yīng)的化學(xué)反應(yīng)試驗(yàn)。注意,爆炸性的反應(yīng),防爆片可能來不及破裂,容器就被破壞了。

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.

 8.請(qǐng)注意,允許的工作壓力應(yīng)低于70%的防爆片的爆破壓力,而不要大于或等于防爆片的爆破壓力。巖征是根據(jù)用戶要求的工作壓力選擇防爆片的爆破壓力的。當(dāng)容器壓力 超過用戶要求的工作壓力時(shí)防爆片就會(huì)破裂。

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.

 9.有18中基團(tuán)會(huì)引起爆炸反應(yīng):

9. There are 18 chemical groups to cause the explosive reaction:

·乙炔化物-Acetylide

·氧化銨-Amine Qxide

·疊氮化物-Azide

·氯酸鹽-Chlorate

·重氨基-Diazo

·重鹽-Diazonium

·次石鹽-Hypohalite

·硝酸鹽-Nitrate

·亞硝酸鹽-Nitrite

·含硝基的化合物-Nitro

·Nitrozo

·臭氧化物-Qzonide

·雷酸鹽-Fuiminate

·高酸-Peracid

·N-胺鹵化物N-Haloamine

·過氯酸鹽-Per chlorate

·過氧化氫物-Hydroperoxide

·過氧化氫-peroxide

 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:

 你從事的化學(xué)反應(yīng)是否為放熱反應(yīng)?反應(yīng)過程中如果產(chǎn)生大量的熱則會(huì)突然劇烈的升高容器內(nèi)的壓力,使容器發(fā)生破壞。

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(xué)反應(yīng)會(huì)有什么副產(chǎn)品產(chǎn)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(huì)產(chǎn)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(xué)反應(yīng)在什么條件下(什么樣的溫度,壓力,催化劑作用下)會(huì)產(chǎn)生失控現(xiàn)象?

Under what conditions (temperature, pressure or catalyst) will the chemical reaction be out of control?

對(duì)于具有高度活性的化合物,如乙炔-acetylene,丁二烯-butadiene,二氧雜環(huán)乙烷-dioxane,乙烯氧化物-ethylene oxide,氧氣-oxygen和其他一切強(qiáng)氧化劑,操作時(shí)必需特別小心。

Special care must be taken to deal with highly active compounds such as acetylene, butadiene, dioxane, ethylene oxide, oxygen and other strong oxidants.

對(duì)任何會(huì)突然釋放大量熱量的試驗(yàn),對(duì)會(huì)產(chǎn)生爆炸性副產(chǎn)品或終產(chǎn)品的試驗(yàn)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.

如果你用新的或性能不清楚的材料做試驗(yàn),建議你先用少量的試驗(yàn)劑做初步試驗(yàn),以了解其性能和試驗(yàn)過程中可能產(chǎn)生的問題。

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.

 11.實(shí)驗(yàn)室必需通風(fēng)良好,反應(yīng)容器要放在實(shí)驗(yàn)室的排風(fēng)罩或排風(fēng)口附近。必要時(shí),尤其是有可燃或有毒氣體產(chǎn)生的可能時(shí),要增加裝置將排出的氣體導(dǎo)室外。必要時(shí)要使用 防護(hù)墻以保證試驗(yàn)的安全,此時(shí)注意到應(yīng)該使用鋼筋水泥做防護(hù)墻,不能用玻璃或鋼化玻璃做防護(hù)墻。

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.

 12.試驗(yàn)室請(qǐng)不要靠近容器的頂部,因?yàn)樵诜辣屏褧r(shí)會(huì)釋放出大量的過熱蒸汽,易燃或有毒氣體,產(chǎn)生巨大的噪聲,傷害人體和破壞聽覺。如有這種現(xiàn)象產(chǎn)生的可能時(shí),則 要用管子將防爆片的出口連到室外,并采取保護(hù)耳膜的措施。

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.

 13.試驗(yàn)中如有可能產(chǎn)生易燃,易爆氣體,所有的電器裝備必需采取防爆措施。應(yīng)將防爆的電器總閘設(shè)在室外。

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.

 14.一般試驗(yàn)材料的裝載量不得超過容器體積的三分之二,因?yàn)橛行┙橘|(zhì)(譬如水)在高溫下體積會(huì)膨脹三倍以上,是壓力突然升高,超過允許的壓力極限。建議盡量用小的裝 載量進(jìn)行試驗(yàn)。

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.

 15.建議不要使用很高的工作溫度或壓力進(jìn)行試驗(yàn),因?yàn)樵趯?shí)驗(yàn)過程中由于化學(xué)反應(yīng),容器的溫度和壓力都會(huì)進(jìn)一步升高,大到不能允許的程度。

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(huì)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.

 17.應(yīng)該均勻地,逐步地用規(guī)定的力矩?cái)Q緊容器的密封螺帽,使各個(gè)螺栓達(dá)到一樣的應(yīng)力狀態(tài)。不要一下子擰緊某些螺帽,然后再擰緊其他螺帽。這樣被先擰緊的螺栓中的應(yīng) 力會(huì)大大高于其他螺栓,是螺紋產(chǎn)生變形。螺帽不要擰得過緊或過松。過松會(huì)導(dǎo)致密封壓力不夠,產(chǎn)生漏氣。過緊會(huì)使螺栓過載,甚損壞。

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.

 18.新容器做試驗(yàn)時(shí)可用50%裝載量的蒸餾水,加溫到150,以檢驗(yàn)容器的密封情況和各控制系統(tǒng)的運(yùn)行情況。

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(shí)驗(yàn)前,檢查墊圈的狀態(tài),如損壞,需及時(shí)更換;如發(fā)現(xiàn)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.
