6维护编辑
（1）装置地：反应釜应安装在符合防爆要求的高压操作室内，在装备多台反应釜时，应分开放置，每两台之间应用安全的防爆墙隔开，每间操作室均应有通向室外的通道和出口，当存在易爆介质时应保证设备地通风良好。
（2）打开包装后检查设备有无损坏，根据设备型号按结构图将设备安装起来，所配备件按照装箱单查清。加热方式如果是导热油电加热，请按照使用温度购买相应型号的导热油（注意：导热油绝对不允许含有水分）加入，加入时将夹套上部的加油口打开并将夹套中上部的油位口打开。通过加油口往里加油，待油位口流油时即可；后将油位口拧死，勿将加油口拧死以免产生压力。
（3）釜体、釜盖的安装及密封：釜体和釜盖采用垫片或锥面与圆弧面的线接触，通过拧紧主螺母使它们相互压紧，达到良好的密封效果。拧紧螺母时，必须对角对称，多次逐步加力拧紧，用力均匀，不允许釜盖向一边倾斜，以达到良好的密封效果。在拧紧主螺母时，不得超过规定的拧紧力矩40~120n.m范围，以防密封面挤坏或超负荷磨损。对密封面应特别加以爱护，每次安装之前用比较柔软的纸或布将上下密封面擦拭干净，特别注意不要将釜体、釜盖密封面碰出疤痕。若合理操作，可使用上万次以上。密封面破坏后，需重新加工修复方可达到良好的密封性能。拆卸釜盖时应将釜盖上下缓慢抬起，防止釜体与釜盖之间的密封面相互碰撞。如果密封是采用垫片（四氟、铝垫、铜垫、石棉垫等）密封，通过拧紧主螺母便能达到良好的密封效果。
（4）阀门、压力表、安全阀的安装通过拧紧正反螺母，即达到密封的效果，联接两头的圆弧密封面不得相对旋转，对所有螺丝联接件在装配时，均须涂抹润滑剂或油料调和的石墨，以免咬死。阀门的使用：针形阀系线密封，仅需轻轻转动阀针，压紧密封面即能达到良好的密封性能，禁止用力过大，以免损坏密封面。
（5）设备安装好后，通入一定量的氮气保压30分钟，检查有无泄漏，如发现有泄漏请用肥皂沫查找管路、管口泄漏点，找出后放掉气体拧紧，再次通入氮气保压试验，确保无泄漏后开始正常工作。
（6）当降温冷却时，可用水经冷却盘管进行内冷却，禁止速冷，以防过大的温差应力，造成冷却盘管、釜体产生裂纹。工作时当釜内温度超过100℃时，磁力搅拌器与釜盖间的水套应通冷却水，保证水温小于35℃，以免磁钢退磁。
（7）安全装置：采用正拱型金属爆破片，材质为不锈钢，按国家标准gb567-89《拱型金属爆破技术条件》制造，出厂时已试验好，不得随意调整。如果已爆破，需重新更换，更换期限由使用单位根据本单位的实际情况确定，对于超过爆破片标定爆破压力而未爆破的应更换，经常使用最好不超过爆破片的下限压力的80%，更换时应注意爆破片凸面向上。
（8）反应完毕后，先进行冷却降温，再将釜内的气体通过管路泄放到室外，使釜内压力降至常压，严禁带压拆卸，再将主螺栓、螺母对称地松开卸下，然后小心的取下釜盖（或升起釜盖）置于支架上，卸盖过程中应特别注意保护密封面。
（9）釜内的清冼：每次操作完毕用清洗液（使用清洗液应注意避免对主体材料产生腐蚀）清除釜体及密封面的残留物，应经常清洗并保持干净，不允许用硬物质或表面粗糙的物品进行清洗。

device (1) : in the high pressure reaction kettle should be installed in accordance with the requirements of the explosion-proof operation indoor, when equipped with many sets of the reaction kettle, should be placed separately, each application security blast walls between two, and each operation room is due to the outdoor channel and exports, should guarantee the equipment when there is a explosive medium well ventilated.
(2) inspection equipment is damaged after open the packing, according to the equipment model according to the chart to equipment installation, equipped with a according to the packing list to find out. if is heat conduction oil heating heating mode, please according to use to purchase the corresponding models of heat conduction oil temperature (note: the heat conduction oil contains water) should never be allowed to join, join the jacketed refueling upper opening and will be jacketed upper oil level in the mouth open. by refueling refueling, mouth flow of oil to oil level; after oil level screw die, not filler will twist death so as not to create pressure.
(3) the installation of the kettle body, the pot cover and the sealing: kettle body and kettle cover use gaskets or cone and circular arc line contact below, by mutual compression, tighten the nuts to make them achieve good sealing effect. tighten the nut, it must be diagonal symmetry, gradually tighten the tension for many times, forcibly even, do not allow the kettle lid tilted to one side, in order to achieve good sealing effect. when tighten the nut, shall not exceed the prescribed tightening torque 40 ~ 120 n. m range, in case of sealing surface collapse or overload wear. on sealing surface should be special care, every time before you install the upper and lower sealing face with more soft paper or cloth to wipe clean, pay special attention to don't put the kettle body, kettle lid sealing surface touch the scar. if the reasonable operation, can use more than tens of thousands of times. after the sealing surface damage, need to be reprocessed repair good sealing performance. remove the kettle cover slowly raise kettle cover should be up and down, to prevent the body between the kettle lid and seal face collide with each other. if the seal is to use gasket (four fluorine, aluminum pad, copper gasket, asbestos pad, etc.) seal, by tighten the nut can achieve good sealing effect.
(4) the installation of the valve, pressure gauge and relief valve through the positive and negative nut tighten seal effect, the circular arc of the connection at both ends not relative rotating sealing surface, for all parts in the assembly, screw connection shall be blotted out graphite lubricant or fuel to reconcile, lest bite dead. the use of the valve, needle valve series wire seal, just gently turn the needle valve, pressure tight cover which can achieve good sealing performance, greatly too forcibly prohibited, so as not to damage the sealing surface.
(5) after installation of equipment, access to a certain amount of nitrogen pressure maintaining 30 minutes, check for leaks, if found to have leakage please use expanded pipe, pipe leakage point search, find out after draining gas tight, again into the nitrogen pressure maintaining test, ensure no leakage after start to work normally.
(6) when the temperature and cooling, can be in cooling water through the cooling coil, rapid cooling is forbidden, in case of excessive temperature stress caused by the cooling coil, kettle body crack. at work when the kettle temperature over 100 ℃, magnetic stirrer and the kettle cover jacket should be between cooling water, ensure that the water temperature is less than 35 ℃, in order to avoid magnetic steel demagnetization.
(7) safety device: using is arched metal rupture discs, material is stainless steel, according to the national standard gb567-89 "arched metal blasting technical conditions", the factory has good test, shall not be adjusted freely. if the blasting, need to replace, change period by using the unit according to the actual situation of the unit, with more than blasting blasting pressure calibration and blasting should be replaced, not often use no more than 80% of the lower limit of rupture disc pressure, blasting should be paid attention to when changing convex upward.
(8) after the reaction, first for cooling, and then the gas through the pipeline leakage within the kettle to outdoors, makes the pressure inside the kettle fell to atmospheric pressure, it is strictly prohibited to bring pressure to remove, then the main bolt, nut symmetrically to loosen, then carefully remove the kettle lid (or rising kettle lid) on the bracket, should pay special attention to in the process of unloading cover sealing surface protection.
(9) inside the kettle erase: after each operation with a cleaning fluid (using the cleaning fluid should be paid attention to avoid to produce the main corrosion) to remove the remains of the kettle body and sealing surface, should often clean and clean, items are not allowed to use hard material or rough surface cleaning.
