I Description of static mixer vacuum resin casting machine

This static mixer vacuum resin casting machine is special for epoxy resin casting dry type transformers, reactors, bushings, current transformers, potential transformers, HV switch insulators, arc-distinguish coils and other electric apparatus. 

This machine adopts STATIC-MIXING technology, developed by ourselves with Patent technologies, similar to HEYDRICH Germany and HUEBERS Germany, suitable for viscosity less than 4000mPa.s mixing. Because of its high intelligent degree, strong continuity and mixing-for-immediate-casting features, casted coil invasion is super high!

III Technology plan achievement

- This plan is a FULL-AUTOMATIC STATIC-MIXING vacuum epoxy resin casting machine, compact structure, high reliability, strong continuity. 

Full automatic means auto drying, degassing, mixing, feeding, counting, vacuuming, heating and casting, controlled by computer. 

- This plan can satisfy all requirements of prevailing dry-type transformer casting, both resin with stuffing or pure resin.

 - This plan is suitable for stuffing feeding from separate warehouse 30m away, very clean casting environment. (Suitable vertical transmitting height 5m; Pre-condition is that hourly transmitting weight is not less than 1000kg)

 - This plan can satisfy requirements by continuous production: Two material storing & degassing tanks feed qualified materials to two counting tanks; Counting tanks feed materials to static mixer; Storing & degassing tanks absorb materials again and degas materials.

 - Storing & degassing tanks adopt umbrella-film-degassing method, perfect degassing result; Because of special design, there will be no sedimentation even material stored for long time.

 - All the related parts & components such as counting pumps, filters, valves and static mixers have been anti-wear treated, avoiding external & internal leakage because of long-time wearing by material.

 - There are cleanable filters between counting pumps and static mixers, avoiding jam inside mixers and casting valves. If filters are jammed, the control system will alarm and prompt settlement way.

 - All counting pumps, static mixers, filters and material transmitting pipelines adopt mesotron-transfer heating method, heating temperature precision is within +/-1ºC! Thus avoids material transmitting failures and proportion error because of material crystallization.

 

- Heating elements are evenly put on tank inner surface, quick heating, accurate temperature control, maintenance free.
