Description
Technical Field
The invention relates to the technical field of air compressors, in particular to an anti-emulsifying system.
Background
The vortex air compressor is widely applied to occasions where compressed air is needed in industries such as industry, agriculture, transportation and the like by virtue of the advantages of high efficiency, low noise, small volume, energy conservation, environment protection and the like. The vortex plate of the main running part of the vortex air compressor is only meshed, and no abrasion is generated, so that the service life of the vortex air compressor is longer than that of a piston type screw compressor, and the vortex air compressor is an ideal power source of pneumatic machinery. In a scroll air compressor, a main moving member scroll is divided into a scroll (i.e., a movable disc) and a fixed scroll (i.e., a fixed disc), and scroll plates are arranged in the movable scroll and the fixed scroll, and in general, the movable scroll and the fixed scroll are combined with each other to form a compression chamber, and when the movable scroll is driven by a crankshaft to translate along a certain circumferential track, the movable scroll moves relative to the fixed scroll, namely, the compression chamber formed by the movable scroll and the fixed scroll moves and changes the volume of the compression chamber, so that the process of sucking, compressing and discharging compressed air is performed. After the air is compressed by the air compressor, high-pressure compressed gas is formed, the air pressure in the air compressor is increased, and the corresponding dew point temperature is also increased. Therefore, the air compressor needs to raise the system temperature to evaporate water, prevent liquid water production, and further prevent the air compressor lubricating oil from emulsifying.
In the prior art, a plurality of means are adopted to prevent the lubricating oil of the air compressor from emulsifying, for example, a heating belt is additionally arranged on the outer surface of the oil-gas separation barrel, but the heating belt has low general power and long heating time, and a large amount of heat loss is caused by surface heating and re-transmission, so that the oil temperature in the system is difficult to heat to be above the dew point; or the heater is additionally arranged in the oil-gas separation barrel, but the heater is additionally arranged in the oil-gas separation barrel, the isolation and fire prevention of the heater and oil are difficult problems, and the local high temperature of the heater can also cause the local oil temperature to be too high so as to deteriorate; or the main motor and other external heat dissipation heat are led to preserve heat for the host, but the temperature cannot be accurately controlled, and the host can be high due to too high temperature. And if the host is down, the temperature of the host cannot be guaranteed. Therefore, the prior art emulsification preventing effect is limited.
