——NEW AND OLD MICROWAVE OVEN CHECK LIST—— | |||
Old type |
Disadvantage |
New design |
Advantage |
Transformer voltage variation |
The circuit is complex, the maintenance is inconvenient, the failure rate is high, and the microwave emission efficiency is low |
Variable pressure of oil cooled power supply |
20%The structure is simple, easy to repair, not easy to fail, and the microwave emission efficiency is increased by 20% |
Straight in waveguide |
The microwave is easily reflected back to the magnetron, causing damage to the magnetron |
A water loaded ring device is added to the waveguide |
Effectively absorbs the reflected microwave to avoid damage to the magnetron |
Waveguide tube homemade |
The size accuracy is not enough, and it has some influence on the microwave efficiency. |
Waveguide tube procurement with professional manufacturers |
more accuracy, more use of microwave conduction |
The cavity material is made of ordinary stainless steel |
Microwave absorption is easy to absorb, and it affects microwave efficiency |
The use of customized plate for the material of the cavity |
It is not easy to absorb microwave and improve the microwave efficiency |
Simple cavity structure |
Microwave can not produce effective resonance in the cavity, which causes the wave to offset each other and reduces the microwave efficiency. |
Design of the cavity according to the microwave emission law |
The geometric design size is more beneficial to increase the number of resonant modes and to ensure a good match between the furnace cavity and the magnetron |
Cavity waveguide layout |

Short circuit ring + graphite resistance microwave |
Unable to effectively stop the microwave leakage of the import and export |
Import and export by short circuit ring + multi Zubo + SiC microwave barrier |
Effectively blocking the microwave leakage of import and export |
Metal mesh bar + asbestos strip is used in door cover leakage protection device |
Microwave leakage prevention is not very ideal |
Leak proof device for door cover using high waterfall silicone strip coated wire and wave retaining device |
The effect of anti microwave leakage is obvious |
35-50%Overall microwave efficiency 35-50% |
Microwave loss too much, waste of energy |
The overall microwave efficiency is 1.5 times higher than that on the original basis |
High utilization rate, more energy saving, increase production efficiency |
