[0035] Example 2

[0036] As Figure 4 shown, the embodiment is basically the same as example 1, the difference is that the fairing 213 in the second blowing assembly 22 is connected with the outer rotor fan 212 at one end, and the other end of the air outlet is a Y-shaped bifurcated structure, and is connected with the water-cooled cylinder 4 and the air-cooled cylinder 5 at the same time.

[0037] The use principle of the utility model is as follows.

[0038] After the motor 7 is powered on, it starts to work and converts electrical energy into mechanical energy, which drives the compressor flywheel 8 to rotate through the belt or chain, and then drives the compressor crankcase 3 connected therewith to rotate, so that the compressor starts to work.

[0040] For the air-cooled cylinder 5, on the one hand, the fan 222 installed on the air-cooled cylinder 5 side mounting frame 221 generates directional airflow directly blowing to the surface of the air-cooled cylinder 5, taking away the heat on the surface of the air-cooled cylinder 5, realizing air-cooled heat dissipation; on the other hand, when the flow guide cover 213 of the second blowing assembly 22 is Y-shaped bifurcated structure, one end is connected with the outer rotor fan 212, and the other end is connected with the water-cooled cylinder 4 and the air-cooled cylinder 5 at the same time, the wind generated by the outer rotor fan 212 is guided to the water-cooled cylinder 4 and the air-cooled cylinder 5 through the flow guide cover 213, the wind flow path is optimized, so that the two cylinders can be effectively cooled at the same time, the uniform distribution of the cylinder temperature is ensured, and the service life of the equipment is prolonged.

[0041] At the same time, the compressor instrument panel 9 monitors the running state of the compressor crankcase 3 in real time, and displays relevant parameters through a pressure gauge and the like, so that the operating personnel can understand the equipment running condition according to the parameters, and timely adjust the equipment running state, so as to ensure that the whole system runs stably and efficiently.
