Embodiment
In order to the object of the utility model embodiment, technological scheme and advantage clearly; below in conjunction with the accompanying drawing in the utility model embodiment; technological scheme in the utility model is clearly and completely described; obviously; described embodiment is the utility model part embodiment; instead of whole embodiments; based on embodiment of the present utility model; other embodiments that those skilled in the art obtains under the prerequisite not paying creative work, belong to the protection domain of the utility model patent.
As shown in Figure 1, a kind of heat recovery exhaust end base of oil injection threaded bolt air compressor system, comprise: screw host 3, be arranged on screw host 3 suction port end air filter 1 and be arranged on screw host 3 bottom stop fuel tap 4, air inlet easing valve 2 is added after described air filter 1, described screw host 3 is leaded up to exhaust check valve 5 and is connected to and is separated oil tank 6, leads up to and stops fuel tap 4 and be connected to oil strainer 10; Described separation oil tank 6 is connected to heat exchanger 16, and described heat exchanger 16 is connected to oil cooler 12 by heat exchanger thermostat valve 15; Described oil strainer 10 is connected with described oil cooler 12 and described heat exchanger 16 respectively.
In described separation oil tank 6, be provided with oil gas essence point device 7, a described oil gas essence point device 7 is connected to cooler 13 by pressure valve 8;
Described oil strainer 10 place is provided with thermostat valve 11;
Described oil gas essence point device 7 place is provided with safety valve 9;
