Two Stage Roots and Rotary Vacuum Pump System for Power Transformer Drying
Brief Introduction
HOPU VPS-300 Transformer Vacuum Pump Set is a new type of vacuuming equipment which is widely used in the vacuuming process in the production, installation and maintenance of many electric power equipments, like electric power transformer, capacitor etc., and is also used in the technical process of industrial production, such as vacuum drying, vacuum distillation, vacuum wielding, vacuum coating etc.
High Efficiency Two Stage Transformer Vacuum Drying Plant is mainly used for vacuum drying and vacuumization while injecting oil in high voltage electrical transformer such as 220KV, 500KV, ±800KV, 1000KV, By selecting world famous German vacuum pumps, the working vacuity can reach up to 10Pa, limit vacuity up to 1Pa. And the GIS interface and vacuum degree intelligent setting are available according to customer's requirement.
High Efficiency Two Stage Transformer Vacuum Drying Plant 's advantages include anti-sucking, fast startup, quick pumping, stable performance and simple operation.
Features
1. The system consists of special Mechanical Booster Roots Pump - Rotary vane vacuum pump combination of vacuum pumps, so the vacuum pumping speed and pressure are obviously better than any other devices.
2. Working vacuum range and maximum vacuum degree are superior to other products.
3. Consist of necessary high quality pipelines and valves to operate the system.
4. Equipped with a control panel with buttons and main breaker for controlling the operation of the two pumps.
5. Installed with special vacuum gauge, Pirani gauge and pressure gauge for accurate online indication.
6. Stable and reliable operation, low noise, and easy to move with trolley.
7. Fully Enclosed for weather proof, can be used in outside fields.
8. Hooks/lifting holes are installed for lifting easily, mobile trailer can also be provided.
