Filter EHC DR405EA030V/-W is a core filter component designed for fire-resistant oil system (EHC system) of power plant. It is mainly used to filter out solid particles, colloidal substances and other contaminants in the oil to ensure the cleanliness of the system oil, thereby ensuring the stable operation of key equipment such as turbines and boilers. With its high-precision filtration capability, high-pressure and high-temperature resistance and wide application scenarios, this filter has become an important component for the maintenance of fire-resistant oil system in the power industry.

Core technical features

1. Multi-layer composite filtration structure

Filter EHC DR405EA030V/-W adopts a multi-layer composite design, including:

- Stainless steel metal mesh: as the primary filtration layer, intercepting larger particle impurities;

- Glass fiber filter paper: achieve medium-precision filtration and effectively remove tiny particles;

- Stainless steel sintered mesh: provides high-precision terminal filtration (precision up to 3 microns) to ensure that the cleanliness of the oil meets international standards.

2. Excellent pressure and temperature resistance

- The working pressure range is up to 21 MPa, which can withstand the impact of high-pressure oil flow;

- The applicable temperature range is -30℃ to 110℃, which is suitable for extreme working conditions, such as cold areas or high-temperature unit operation.

3. High strength and long life

- The stainless steel skeleton and punching plate design ensure the structural integrity of the filter element under high pressure differential alternating load;

- The large dirt holding capacity can carry pollutants for a long time and reduce the replacement frequency.

The Filter EHC DR405EA030V/-W is widely used in the fields of power, petrochemical, metallurgy, etc., especially in the fire-resistant oil system of power plants:

- Thermal power and nuclear power: used for oil purification of steam turbine speed control system and boiler lubrication system to prevent precision parts from wear due to pollution;

- Hydraulic control system: filter particulate matter in fire-resistant oil to ensure the sensitive response of servo valves, oil motors and other equipment;

- Auxiliary equipment: such as impurity control of hydraulic circuits such as feed water pumps and fans.

Technical advantages and industry value

1. Improve system reliability

Through high-efficiency filtration, the equipment failure rate caused by oil contamination is significantly reduced, and the overhaul cycle of the unit is extended.

2. Reduce maintenance costs

The long-life design reduces the frequency of shutdown and replacement, while avoiding the equipment damage and maintenance costs caused by oil contamination.

3. Environmental protection and safety

The filter element material is highly compatible with fire-resistant oil, avoiding the risk of chemical corrosion, and meets the manufacturing standards of environmental protection equipment.

Filter EHC DR405EA030V/-W has become an indispensable component of the EHC system of power plants due to its precision filtration technology, high-strength structure and wide applicability. For power companies that pursue efficient operation and maintenance and cost control, choosing this product is not only a reflection of technological upgrading, but also a long-term investment to ensure the safe and stable operation of the unit.
