China atlas copco air compressor daily checklist Manufacturer, Supplier, Factory

The non-driven side motor assembly of the Atlas Copco oil-injected screw compressor is the part of the motor that is separated from the connection end of the compressor main body. Although it does not directly participate in power transmission, its structure and performance are of vital importance to the overall operational stability, heat dissipation effect, and safety of the equipment of the motor.

The entire maintenance package has a lower price and can be purchased in bulk. It optimizes inventory management and reduces costs caused by downtime

Atlas Copco 2230004015，Load solenoid valve: Usually a two-position three-way normally closed valve. When powered on, it allows compressed air to enter the cylinder pipe of the intake valve from the oil-gas tank, opening the intake port; when powered off, it cuts off the air path and discharges the air in the cylinder, closing the intake port. For example, the load solenoid valve of Ingersoll Rand achieves this function through PLC instructions. Safety relief solenoid valve: Mostly a two-position two-way normally open valve. When the air compressor is unloaded or shut down, it is powered off, releasing the gas in the oil-gas tank to the intake filter to ensure the system pressure drops to a safe range. In small air compressors, the solenoid valve connects the cylinder outlet to the outside when the machine is shut down to release residual pressure and prevent the motor from starting under load, causing overload; when starting, it closes the pressure relief channel to allow compressed air to be normally filled into the air tank. For example, the safety relief solenoid valve of Fuxinair air compressors indirectly regulates the movement of mechanical devices by controlling the opening and closing of the oil circuit.

Maintenance and Replacement Suggestions for Atlas Copco Oil Coolers Regular Cleaning: For air-cooled coolers, clean the dust and oil stains on the fins regularly. For water-cooled ones, check if the water channels are blocked or clogged to ensure the cooling effect. Leak Check: During daily inspections, observe if there are oil stains on the surface and interface of the cooler. If leakage is detected, replace the sealing parts or the entire kit promptly. Replacement Timing: When the cooler shows severe corrosion, large-scale damage to the fins, or internal blockage causing abnormal oil temperature rise (above the specified upper limit of the unit), it is recommended to replace the entire kit. Preferentially use Atlas Copco original accessories to ensure compatibility with the unit and cooling performance. The reliable operation of this kit directly affects the energy consumption, stability, and service life of the oil-free air compressor, and is an important guarantee for maintaining the efficient operation of the unit.

Maintenance recommendations for the oil filter of Atlas Copco screw air compressors: Replacement cycle: Under normal operating conditions, replace the filter once every 2,000 - 3,000 hours. In harsh environments (such as high dust and high temperature), this period should be shortened to 1,500 hours. Synchronous operation: When replacing the filter element, also simultaneously discharge the settled oil at the bottom of the oil tank (containing a large amount of impurities) and refill the oil to the specified level. Selection requirements: It is necessary to select original factory or certified filter elements that match the compressor model to avoid equipment damage due to size mismatch or insufficient filtration accuracy. Effective maintenance of the oil filter can significantly reduce the wear rate of the screw main unit and is a key aspect of the daily maintenance of the compressor unit with low cost and high efficiency.

Working principle： Expansion and contraction driven: The constant temperature valve mainly operates based on the principle of thermal expansion and contraction. Special expansion temperature-sensitive paraffin wax and other components are usually used as the temperature sensing elements. When the oil temperature rises to the melting point of the paraffin wax, the wax expands significantly, generating a large force that pushes the push rod, causing the valve core to move and opening the valve; when the oil temperature drops, the paraffin wax contracts due to the cold, and under the spring rebound effect, the valve core resets, closing or reducing the valve opening. Oil passage control: The expansion and contraction of the valve core is used to adjust the changes in the oil passage between the valve body and the housing, thereby controlling the proportion of lubricating oil entering the oil cooler. When the oil temperature is lower than the set value, the valve closes or the opening degree decreases, and the lubricating oil directly returns from the oil-gas tank to the main unit, achieving rapid heating; when the oil temperature is higher than the set value, the valve opens, allowing the lubricating oil to enter the cooler for cooling, and the cooled lubricating oil returns to the main unit, thereby ensuring that the rotor temperature remains within the set range.
