Embodiment 1

[0039] Such as figure 1 , figure 2 and image 3 As shown, the air compression device of the electric oil-free main air compressor of the present embodiment 1 includes an integral main casing 3 and a compression cylinder assembly arranged on the main casing 3 and connected to the inside of the main casing 3, the main casing Body 3 is provided with crankshaft 1, fan end bearing 2, large counterweight 4, swing rod bearing 5, swing rod 6, small counterweight 7, motor end bearing 8 and shaft coupling 9; the compression cylinder assembly consists of a low-pressure cylinder Cover 14, output joint 15, valve plate screw 16, exhaust reed 17, valve plate 18, intake reed 19, low-pressure cylinder body 21, and pad 20 set in low-pressure cylinder body 21, low-pressure cylinder Cylinder liner 22, piston ring 23, support ring 24, low-pressure piston 25, connecting rod small end bearing 26, oil seal 27, piston pin 28, heat insulating ring 29, compression screw 30; piston ring 23 and support...

Embodiment 2

[0051] The main features of this embodiment 2 are: the compression cylinder assembly is composed of two high-pressure cylinder assemblies 11 and two low-pressure cylinder assemblies 10, and the two high-pressure cylinder assemblies 11 and two low-pressure cylinder assemblies 10 are X-shaped on the main housing 3 set up. All the other features are with embodiment 1.

[0052] In Example 1 and Example 2, as figure 1 and image 3 As shown, the rotation of the motor transmits the torque to the coupling 9, and then drives the crankshaft 1 to rotate. The fan end bearing 2 and the motor end bearing 8 provide support and fixation for the crankshaft 1. The rods 6 are all installed in this turning groove. When the crankshaft 1 rotates, the four swing rods 6 will move up and down. The swing rod bearings 5 ​​provide support and fixation for the swing rods 6. The large counterweight 4 and the small counterweight 7 are Provide force balance during the movement of the main body of the air ...

Abstract

The invention discloses an air compression device of an electrical oil-free main air compressor, and belongs to the technical field of air compressors. The air compression device comprises a main housing, a crankshaft, a fan end bearing, a large counterweight block, a swinging rod bearing, a swinging rod, a small counterweight block, a motor end bearing, a coupler and a compression cylinder component; the compression cylinder component consists of a low-pressure cylinder cover, an output connector, a valve plate screw, an exhaust reed, a valve plate, an air inlet reed, a low-pressure cylinder body, a cushion block, a low-pressure cylinder sleeve, a piston ring, a supporting ring, a low-pressure piston, a connecting rod small end bearing, an oil seal, a piston pin, a heat insulation ring and a compression screw; the compression cylinder component consists of at least one high-pressure cylinder component and at least two low-pressure cylinder components; the piston ring and the supporting ring are made of teflon; the oil seal avoids leakage of bearing grease; the heat insulation ring insulates heat of the low-pressure piston. Oil leakage and blow-by hidden dangers of the air compressors are eliminated through air cooling, and a reasonable air flow trend is formed. With the adoption of the piston ring and the supporting ring that are made of teflon, no oil cooling is required, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to an air compression device, in particular to an electric oil-free main air compressor air compression device, which belongs to the technical field of air compressors. Background technique [0002] The oil-free air compressor is the main body of the air source device. It is a device that converts the mechanical energy of the prime mover (usually an electric motor) into gas pressure energy. Oil generally refers to the oil content of the gas discharged from the exhaust port of the air compressor. Generally, the oil content of the machine with oil is relatively large, and the oil content of the oil-free air compressor is 0.01ppm, and the other is the oil-free air compressor. Machine, it is not lubricated by oil, but lubricated by resin material, so the final exhaust gas does not contain oil, which is called oil-free air compressor, but in the past, this kind of air compressor was easy to lose the sealed grease, which caused the bear...
