Micro reactor（www.gfanyingfu.com） in use is the most commonproblem is a leak, once leak the whole experiment is white, so that beforedoing the experiment to check the leak (leak check method, pressure to thekettle filled, standing for a period of time, observe the pressure gaugepressure is decreased, if not explain does not leak; if there is a decrease inthe requires with foam water droplets to suspicious place, the leak willbubble). General leakage of the place where the kettle cover and the kettlebody sealing valve leakage, leakage of joints. If the kettle cover and thekettle body seal leakage, you need to replace the sealing ring, and some of thekettle is hard seal no seal, this is the most difficult to repair, once theleak must be sealed surface damaged, it is to return to the factory for repair.If the valve is leaking, only need to use a wrench on the line, it is notnecessary to replace the valve.
The sealing ring of the maintenance, closeto the body before the careful inspection of the kettle cover in the gasket toensure that it is intact. After many times experiments, gasket inside andoutside diameter edge may outward extrusion thin irregular edges. This does notmean that washer needs to be replaced, only to the flange is removed with thesharp knife. The joint surface of the kettle cover and the kettle body ischecked to ensure that they are smooth and without convex marks, and the kettlecover is put on the kettle body.
Needle valve maintenance, after long timeuse needle may will need to adjust the seal, such as long time no (2 days) tomaintain the open state. The kettle on all valves are dual card sleeve seal, inorder to prolong the service life, please try to reduce the needle head sleevenut disassembly, if too frequent disassembly will gradually unable to guaranteethe good sealing.
