Double glass reactor malfunction simple exclusion
1 Open the double glass reactor power switch, indicator light does not shine. External power supply or bad, please do not pass the professional electrician check thepower outlet.
2 fuse circuit, the double glass reactor power switch in the OFF position, and back toset fuses.
3 double glass reactor power indicator light, but does not rotate. Axis of rotation ruststop using, contact the vendor motor, electrical box is not connected seven-pin plugfailure to reconnect seven-pin plug
4 double-layer vacuum glass reactor suddenly disappeared, there are cracks in the glass, the switch checks the glass parts are damaged, transfer switch
5 double glass reactor with a vacuum, but not on the pumping ring wear, leaks, replace the connecting ring vacuum switch, switch

Heat exchanger tube bundle problem
Heat exchanger tube bundle problem
The heat exchanger baffles, fixed rods, tube plates, and floating head cover, etc.,should be visually inspected to confirm the availability of corrosion and deformation,check the gasket for damage or aging. Check the heat exchanger tube plate and thehead without distortion.
The heat exchanger tube bundle thickness measurement is to check one of the basic content. The results of previous thickness measurements should be recorded forcomparison and trend analysis. An outer tube of the fin thickness depends on a dedicated ultrasonic thickness measurement probe or eddy current probe from thetube for testing. Sometimes, you can also use the sampling approach to treatment.

Guidebooks double glass reactor
1, double glass reactor with a carefully before examination, and whether there isbroken glass, the interface is consistent, attention gently.
2, double glass reactor with a soft cloth (napkin available alternative) to clean theinterface, and then smear a little vacuum grease. (Vacuum grease after use must becovered to prevent dust sand to enter.)
3, the interface is not over-tighten, loosen regularly active, cause the connector to avoid long-term locked killed.
4, first open the power switch, and then let the double glass reactor from slow to fastrunning, shutdown the machine is stopped to make, and then switch off.
5, double glazing throughout PTFE reactor had to tighten the switch can not be easy to damage the glass.

Fiber welding of plate-fin heat exchanger
Fiber welding of plate-fin heat exchanger
Welding of the fiber plate-fin heat exchanger, in addition to a collection box for both sides and weld thickness for surface crack detection, the main vacuum leak through the sides, respectively, to confirm their status. If the pressure test and found a leak,more easily found.
If leakage can be cut either side of the collection box, with another example of fillingpressure method, to identify the specific leak channel, for repairs to provide the correct basis. If the plate-fin heat exchanger is used for air separation plant in the main evaporator, in order to prevent the operation of liquid oxygen in the carbonmaterial should be kept within the plot is usually the oxygen leak channel blocked.Therefore, when conducting the leak. Channel should be inflated in nitrogen, oxygengas tank side of the cut set.

Operation of the external heat exchanger
Operation of the external heat exchanger inspection
A, heat exchanger base and bearing inspection. The basis of the heat exchangeris generally added by the saddle bearing concrete foundation formed, there are a fewof the heat exchanger are the basis of bearings and steel. On the concrete foundationshould first be visually inspected for cracks, spalling. The site of the suspectedsample can be checked. The heat exchanger shell and the gap between the saddle,should be carefully examined to confirm whether they occurred due to presence ofwater vapor corrosion. The saddle is usually welded with the heat exchanger shell. In this case, you should check the saddle between the anchor bolt hole and foundationbolts if there is room for expansion and contraction, and make sure not to tighten the bolt, one end of the saddle can move freely. Application Level check the concrete foundation subsidence, and visual inspection of the piping is related to the occurrence of distortion. If necessary, can be combined with vertical and horizontalhanging instrument measured way to verify the level of degree.
B, heat exchanger piping inspection. Running in the heat exchanger can beconnected to its external takeover checked for leaks. Operation were found to havesevere leakage nozzle, the suspension should be open connecting flange, replace the gasket, check the flange seals have groove-like damage.

Heat Exchanger Inspection Program
Heat exchanger inspection program should normally be processes and equipmentmaintenance management operations department in consultation with departmentsto determine. Plant operations department can process operating conditions,material changes in composition and other parameters to determine the overall heat transfer performance of heat changes and confirm the leakage situation.
Equipment maintenance management process operation according to the preliminary findings, combined with past history, the focus of this inspection to determine the content and focus area. Heat exchanger pressure shell, head, pressure vessels belonging to the scope of the inspection so they should first refer to the labordepartment in-service pressure vessel safety supervision requirements made by the technical aspects of security checks.

Reactor operation checks
Reactor operation checks
1 reactor before the operation to prepare the necessary driving tools such aswrenches, pipe wrenches, etc.;
2. checked before reactor operation safety valve, explosion-proof membrane,pressure gauges, thermometers and other safety devices are sensitive good
Use, safety valve, pressure gauge is in the calibration period, and the seals intact, the red line gauge whether the program is correct;
3 reactor operation checks reactor flange and base such as whether the bolts loose,security guard is intact and reliable;
4 reactor operation checks to confirm the device with a blue clamp Dafa no loosening, no small number, no residue, and arranged with a uniform distribution;
5 Confirm reactor operating oil level in sight glass reducer 1 / 2 to 2 / 3 between theautoclave box with a mechanical seal oil ring oil level higher than the static and dynamic sealing surface;
