What are the methods of screw air compressor de-oiling? In the process of screw air compressor repair work, causing the temperature of the compressed air to rise, heat will be transmitted from the compressed gas through many places, the higher the screw air compressor exhaust temperature, the shorter the service life of the oil fraction. Because of the high temperature, there will be more lubricant in the gas state, increasing the difficulty of the work of the oil. Higher temperatures inevitably reduce the service life of the lubricant, as well as the service life of all seals and piping. So how to solve the air compressor oil scale?

Screw air compressor equipment in the operation process too high oil temperature will reduce the gas transmission coefficient and increase the power consumption, and even bearing loose beads thing help. Excessive temperature will also make the lubricant in the metal catalyzed thermal decomposition, generating work harmful free carbon, gum and water, accumulated over time, these substances if the instant high temperature will lead to the formation of carbon deposits, and in severe cases lead to the host screw bite dead.

The solution to the air compressor system scale, gums or carbon buildup is cleaning.

At present, most of the air compressor after-sales service units use online cleaning agent, acidic cleaning agent, alkaline cleaning agent and solvent-based cleaning agent, acidic and alkaline cleaning agent is generally referred to as not based on cleaning agent. Solvent-based cleaners and water-based cleaners have their own advantages and disadvantages:

1. Online carbon cleaning agent is generally selected oil-based cleaning agent. Divided into two kinds, one is an additive, can be added to the upcoming maintenance of the compressor oil circuit in proportion to the random operation, the main decomposition of the oil circuit system to clean up the light oil; a cleaning oil, the compressor maintenance before the discharge of the old oil, the direct filling of the cleaning oil, to be run for 30 minutes to 2 hours to discharge, the system is refilled with new oil. If the system gel or carbon is serious, it is recommended to use water-based cleaning agent or solvent-based cleaning agent to dismantle the machine immersion cleaning.

2. Water-based cleaning agent is a water-based cleaning products, safe for the environment. Generally to cycle cleaning, immersion cleaning effect is relatively slow, and organic solvents as a substrate compared to the product has many advantages, such as: cheap, easy to use. Disadvantages: large amounts of water are required for rinsing. The alkaline cleaning agent reacts with the oil to generate soluble compounds, which dissolve the grease, and then water is used to rinse it off. Cleaning needs to be carefully observed to prevent the formation of point corrosion caused by the alloy's intergranular dechromatization.

3. solvent-based cleaning agent is an organic solvent-based cleaning products, solvent-based cleaning agent is roughly divided into two kinds: one is composed of two layers of liquid, the upper layer of aqueous protective liquid cover, the lower layer of solvent-based cleaning agent for the penetrating agent; the other is a penetrating agent and synergist refined into a pure solvent-based cleaning agent. After the cleaning effect are more obvious, the latter's shortcomings are low boiling point, volatile faster; Advantage is that no residual moisture after cleaning, rapid drying, do not need to use water to clean.
