In the power core of industrial production – the screw air compressor system, the air intake processing stage is like the respiratory system of the human body, directly affecting the operational efficiency and lifespan of the equipment. Among them, the air filter and the intake valve, this “golden pair”, undertake a crucial protective responsibility.
Air Filter: The “Respirator” of the Equipment
As the first line of defense in the air path system, the air filter adopts a multi-layer composite filter material design. Its core filter layer is composed of ultra-fine glass fibers. This special material can effectively intercept particles in the air larger than 1 micron, with a filtration efficiency of up to 98%. In dusty working conditions, a high-quality filter can extend the rotor lifespan of the main unit by more than 30%. The latest test data shows that when the pressure difference exceeds 500 Pa, the filtration efficiency can still maintain over 95%, but it should be replaced in time to avoid energy consumption increase. In dusty areas the filter element may be provided with a pre-separator (air intake side) in the shape of a foam mat or a fleece.
Intake Valve: The Precise “Respiratory Regulator”
Working in coordination with the filter, the intake valve adopts a butterfly valve or piston structure, and automatically controls the opening degree through an air pressure signal. When the equipment starts, the intake valve opens slowly to avoid current shock; in the unloaded state, it is completely closed to reduce idle loss. The actual measurement data from a cement factory shows that after configuring an intelligent intake valve, the equipment’s idle energy consumption is reduced by up to 15%. The specially designed noise reduction structure can also control the intake noise below 75 decibels.
Maintenance Key Points for the Combination
There are differences in the maintenance cycles of this pair: The filter needs to be replaced every 2,000 hours, while the intake valve usually only requires regular cleaning of the valve plate and inspection of the sealing performance. It is worth noting that both must match the air volume requirements of the model, and being too large or too small will lead to abnormal energy consumption.
