Model ZLH Transformer Vacuum Pump Machine
Introduction:
Model ZLH transformer Vacuum Pump Machine is used in transformer installation and maintenance for transformer vacuum drying and Transformer vacuum pumping. Quick air pumping, energy consumption, mobile and flexible features.
The vacuum pump system ZLH equipped with anti-oil-back device and phase sequence automatic commutation system to prevent the vacuum pump from reversing.
Features:
1. Applying for vacuum drying and vacuum measurement of transformers, tap changers, SF6 switches, etc.
2. Cooling type: natural air-cooled. The vacuum pump exhaust port is provided with device for condensing and collecting moisture.
3. Easy operation, control system has the alarm functions with phase sequence, over-voltage, short-voltage, leakage detection, etc.
4. Almost free maintaining, Automatic operating control.
5. Vacuum pump with self-check valve, vacuum pump interlock, in the power outage or vacuum pump stop automatically closed when the check valve.
6. Digital Pirani vacuum gauge is installed to detect the vacuum degree of the transformer.
