Product Introduction
The VRC series static mixing vacuum casting equipment is mainly used for epoxy resin casting production of dry-type transformers, dry-type bushings, basin insulators, dry-type transformers, high-voltage switch insulation components, and other electrical products.
overview
Suitable for pouring electrical insulation products with and without fillers;
Suitable for vacuum degassing, mixing, and casting of high molecular weight materials such as bisphenol A epoxy resin, purple ring outdoor epoxy resin, polyurethane, etc;
Suitable for the processing of mixed materials with self added fillers by users and the processing of two-component pre mixed fillers, with a viscosity range from 10 centipoise to 20000 centipoise, and a wide range of applications.
Modular assembly of equipment, easy installation, simple operation, high degree of automation, and easy for operators to master.
According to user needs, the equipment system can be reasonably configured to provide various types of vacuum casting equipment and mixing systems mainly using static mixing methods.
Main features of the equipment
1. Advanced static mixing system
Adopting advanced static mixing technology, high-pressure feeding by metering pumps, continuous mixing by static mixers, continuous operation of feeding, static mixing, and automatic pouring, and automation of the pouring process; The components involved in the mixing are very small, and the viscosity of the mixed material is low. It is poured while mixing, with excellent permeability and wetting properties, ensuring the quality of the poured product; The mixing and pouring process adopts automated control to prevent operators from making mistakes; The amount of mixed residual materials is very small, effectively reducing material loss and maximizing environmental protection;
2. Automatic pouring and distribution system
Adopting an automatic pouring valve, each pouring port is connected to the corresponding mold, and the touch screen is used for on-site control.
The pouring amount of each set of molds can be automatically controlled through a metering pump, and the pouring amount of each batch is recorded in the computer for easy query and tracking;
3. A complete vacuum system
All material preparation, batching, feeding, and pouring of the equipment during the production process are carried out in a vacuum state, effectively removing moisture and other gas impurities to ensure that the poured products meet the insulation level requirements.
4. Reliable measurement system
For static mixing and pouring equipment, a metering pump made of superhard wear-resistant material is used for metering, which runs reliably, and the dynamic metering accuracy can be guaranteed within 1%, with a service life of more than 1 million times; High precision electronic weighing systems, flow meters, and imported feeding pumps are used on other types of pouring equipment to achieve precise material preparation control.
5. Advanced and safe heating technology
The mixing tank used for degassing treatment uses thermal oil as the heat transfer medium for heating, which has the advantages of safety and reliability, high temperature control accuracy, good temperature uniformity, and no local overheating.
The pouring tank for placing the pouring mold is heated by highly reliable electric heating elements, which have the advantages of energy saving, simplicity, reliability, and aesthetics.
6. Advanced and reliable measurement and control system
The main control system adopts computer control technology, and key processes and processes that are prone to manual errors are all controlled by computer chain control technology. Process modification, process curve recording, and process parameter adjustment can be easily achieved through computers. The entire equipment measurement control and vacuum control are automatically set and controlled, and the overall performance of the measurement and control system has reached the international advanced level.
7. Multiple measures to ensure the safety and reliability of equipment
Strengthen quality awareness from the design source, and select and match original branded products.
Each unit system is designed in a modular manner and is assembled and tested before leaving the factory.
Important systems such as metering, vacuum, and electrical control are simulated and operated according to the actual working conditions of users, further enhancing the adaptability of the system.
The vacuum system, heating system, and pressure tanks with safety requirements are all equipped with reasonable safety interlock measures, and are manufactured, installed, and inspected strictly in accordance with the requirements of relevant national departments.
