Vacuum oil injection equipment is a specialized device that
achieves efficient and bubble free oil injection through a vacuum
environment. It is widely used in power equipment (such as
transformers and mutual inductors), mechanical manufacturing,
automotive parts, aerospace and other fields. Its core function is
to remove gas and moisture inside the oil injection object through
vacuum pumping, ensuring that there are no bubbles or pollution
during the oil injection process, and improving the reliability and
lifespan of the product.
Characteristics and core highlights of vacuum oil injection
equipment products
1. Vacuum degassing technology to eliminate residual bubbles
High vacuum degree: Using an efficient vacuum pump set, quickly
evacuate (vacuum degree can reach below 10Pa), completely eliminate
oil and gas, water in the oil injection chamber, and avoid
insulation performance degradation or mechanical wear caused by
bubbles.
Bubble free oil injection: Ensure that the oil penetrates into fine
pores, improving the insulation performance and operational
stability of equipment (such as transformers).
2. Intelligent control, precise and efficient
Fully automatic process: PLC+touch screen control system, preset
oil injection parameters (pressure, time, oil volume), one click
operation, reducing human error.
Real time monitoring: Integrated pressure sensor and liquid level
sensor, real-time display of vacuum degree, oil temperature, and
oil injection volume, automatic alarm and shutdown for abnormal
situations.
Multi mode options: Supports batch production mode or customized
oil injection process to meet different process requirements.
3. Efficient filtration and purification, pure oil quality
Multi stage filtration system: Built in high-precision filter
element (optional 1-5 μ m), removes particle impurities and
moisture from the oil, and extends the service life of the
equipment.
Circulating purification function: During the oil injection
process, the oil can be circulated and filtered to ensure that the
cleanliness of the oil meets NAS 1638 or ISO standards.
4. Energy saving and environmentally friendly design
Oil mist recovery device: The vacuum exhaust port is equipped with
an oil mist separator to prevent oil mist emissions from polluting
the environment and comply with environmental regulations.
Low energy consumption operation: Optimize the energy consumption
matching between the vacuum system and the oil pump, saving more
than 30% energy compared to traditional equipment.
5. Modular structure, flexible adaptation
Multi specification compatibility: The oil injection amount (from a
few to several tons), oil type (insulation oil, lubricating oil,
etc.), and interface size can be customized according to user
needs.
Convenient mobility: Available in fixed or mobile designs (with
swivel wheels), suitable for various scenarios such as workshops,
laboratories, and on-site operations.
6. Safe and reliable, easy to maintain
Explosion proof design: Suitable for flammable and explosive
environments (such as the petrochemical industry), key components
use explosion-proof motors and materials.
Self cleaning function: Some models are equipped with an automatic
pipeline blowing system to reduce oil residue and lower maintenance
frequency.
Long life components: The core components (vacuum pump, seals) are
imported brands to ensure long-term stable operation of the
equipment.
Application scenarios of vacuum oil injection equipment
Power industry: Vacuum oil injection for transformers, mutual
inductors, and capacitors.
Automobile manufacturing: high-precision oil injection for engines,
transmissions, and hydraulic systems.
Industrial equipment: pollution-free lubrication for hydraulic
machinery, precision instruments, aerospace components.
In the field of new energy: insulation oil filling for wind power
gearboxes and energy storage equipment.
