New and old microwave oven check list

Disadvantage	Advantage
Transformer voltage variation	The circuit is complicated, inconvenient to maintain, has a high failure rate, and the efficiency of microwave emission is low.	Variable pressure of oil cooled power supply	The structure is simple, easy to repair and not prone to failure, resulting in a 20 percent increase in microwave emission efficiency.
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 absorbing reflected microwaves 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 precision, more use of microwave conduction
The cavity material is made of ordinary stainless steel	Absorb easily, which affects microwave efficiency	The use of a custom plate for the material of the cavity	It is not easy to absorb microwaves and improve 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 + asidealos 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
The total microwave efficiency is 35-50%	Microwave loss is excessive and wastes energy.	The overall microwave efficiency is 1.5 times higher than that on the original basis	High utilization rate, greater energy savings, increased production efficiency

Microwave vulcanization production line and process technology

Product advantage

• Selection of industrial special waveguide tube accurate, more use of microwave conduction.
• The material of the cavity is made of custom-made plate, which is not easy to absorb microwave and improves microwave efficiency.
• The cavity is designed according to the law of microwave emission. The geometric design size is more conducive to increasing the number of resonance modes and ensuring a good match between the furnace cavity and magnetron.
• Import and export use short-circuit ring + multi-segment resistance wave + silicon carbide resistance microwave, effectively stop the microwave leakage of import and export.
• The anti-leakage device of door cover adopts high temperature resistant silicone strip coated wire+wave-blocking device, which has obvious anti-microwave leakage effect.
• The shape frame adopts laser cutting iron plate folding type, which is beautiful and atmospheric.
• The size of the internal structure is the same as that of the peers (6.8m). On this basis, it is extended to 8m, and the ideal vulcanization speed can be achieved by combining hot air with microwave more effectively. In addition, vulnerable parts of conveyor belt are also common with vulcanization equipment, which provides convenient conditions for customers to produce.
• Microwave control system can achieve constant output of microwave power. Even if one group of microwave fails, it can also distribute its power to the other groups, so that the microwave output power can be constant and the effect of microwave on product vulcanization can be avoided.
