Such as, in the time that summer, rock gas fuel injection helical lobe compressor was just started shooting, because lubricating oil temperature does not meet fan starting condition, can not utilize gas cooler to dispel the heat to compressor air-discharging, can cause compressor exhaust temperature not meet the demands;
And for example, when compressor air-discharging does not need to dispel the heat (as winter ambient temperature-30 DEG C time), if lubricating oil temperature meets fan starting condition, blower fan can dispel the heat to gas cooler, lube oil cooler simultaneously in air blast, thereby gas cooler is dispelled the heat to compressor air-discharging, cause compressor exhaust temperature to be down to-20 DEG C of left and right, can cause gas exhaust piping to freeze, frozen block, causes irremediable loss.
In addition, the gas cooler in existing rock gas fuel injection helical lobe compressor, lube oil cooler function singleness, only play cooling effect to compressor air-discharging and lubricant oil, and its purposes need further expansion.
Model utility content
For the defect existing in above-mentioned prior art, technical problem to be solved in the utility model is to provide one can independently control delivery temperature, lubricating oil temperature, and the cooling unit for rock gas fuel injection helical lobe compressor of energy auxiliary compressor unit heat radiation.
In order to solve the problems of the technologies described above, a kind of cooling unit for rock gas fuel injection helical lobe compressor provided by the utility model, this device comprises vented cavity, and be arranged on respectively cooling lagging, gas side cooler, oily side cooler, the cooling blower in vented cavity, described vented cavity offers ventilating hole, it is characterized in that:
The inner chamber of described cooling lagging goes out an air-out passage and two air intake passages by baffle for separating, and the outlet of two air intake passages is drawn cooling lagging through air-out passage, the be placed in export department of two air intake passages of gas side cooler and oily side cooler;
Described cooling blower has two, the be placed in import department of two air intake passages of these two cooling blowers, the just import to two air intake passages respectively of the outlet air end of two cooling blowers.
Further, the ventilating hole of described vented cavity has two, and these two ventilating holes are respectively the first ventilating hole, the second ventilating hole, and the first ventilating hole is wherein equipped with for regulating its air inflow blind, and the second ventilating hole is equipped with dismountable ventilative cover plate.
The cooling unit for rock gas fuel injection helical lobe compressor that the utility model provides, by coordinating of air intake passage and cooling blower, can utilize independently cooling compressor delivery temperature of gas side cooler, also can utilize independently cooling and lubricating oil temperature of oily side cooler, can independently control delivery temperature, lubricating oil temperature, utilize two ventilating holes of vented cavity, and the cooperation of blind, ventilative cover plate, can also the heat radiation of auxiliary compressor unit.
