Rubber Single Extrusion And Microwave Curing Production Line

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
