Problems solved by technology

[0004] No matter what kind of air compressor, there is one thing in common: the air compressor and the power machine are separated, and the air compressor is driven by a special power device, such as a motor, an internal combustion engine, etc., and the two are generally connected by a belt or a coupling. In addition, if the power machine is a high-power internal combustion engine, a special matching starter is required, so that the whole set of air compressor equipment will have bulky, complex equipment, many auxiliary equipment, and energy loss during transmission. and other shortcomings
Moreover, since the power machine and the compressor have their own product series, it is not easy to match the power equipment and the compressor during use, that is, the phenomenon that the power output by the power machine in the best working state does not match the power required by the compressor, so easy Either the power machine is overloaded and the service life of the equipment is shortened; or the power output by the power machine does not reach the design value and the equipment is in a waste state, and this mismatching state also causes a waste of energy

Embodiment 1

[0085] As shown in Figure 1, the power cylinder 8 and the compressor cylinder 12 of the self-driven air compressor are integrated on the same crankshaft 45, and all the main journals of the crankshaft 45 are installed on the bearing housing composed of the body 2 and the bearing cover 44 through the sliding bearing 32 Above, the number of sliding bearings 32 is the same as the number of main journals of the crankshaft 45 , and the bearing cover 44 and the body 2 are fastened together by the bearing cover bolt assembly 38 . A cylinder head 4 is provided at the upper end of the cylinder body 2, and a cylinder gasket 3 is arranged between the two to ensure that there is no water leakage or air leakage between the cylinder body 2 and the cylinder head 4. on body 2. The camshaft mounting seat 21 and the camshaft cover 6 are respectively installed on the cylinder head 4 through the bolt assembly 13 and the bolt assembly 5 . A fuel supply device 9 is arranged corresponding to each p...

Embodiment 2

[0098] The difference from technical solution 1 is that the exhaust gas use of the power cylinder has changed, mainly reflected in: ① cancel the exhaust gas turbocharger 70 between the intake and exhaust of the power cylinder; ② the exhaust pipe of the power cylinder 8 is leaving The exhaust pipe 51 of the power cylinder is divided into two parallel branches: one is equipped with a heat exchange valve 81 and connected in series with the heat exchanger 83; Converge into one road again, and flow through the exhaust gas post-processing device 71 to be emptied; ③The exhaust gas from the compression cylinder also passes through the heat exchanger 83 and is heated by the exhaust gas from the power cylinder.

Abstract

An integrative air compressor of self-driven type comprises a machine body, a power cylinder and an air cylinder. The power cylinder and the air cylinder, which are arranged alternately, are mounted on the machine body and share a crankshaft. One end of the machine body is provided with an end cover and a driving timing gear system arranged at the corresponding end plane of the machine body is in the end cover of the machine body. A first camshaft, a second camshaft and an oil pump spindle, which are arranged on the fitting seat of the camshaft, are connected with the timing gear arranged on the crankshaft by a timing synchronous cog belt and a timing gear pair of the driving timing gear system. A plurality of corresponding cams on the first camshaft respectively correspond to the inlet valve component of each power cylinder and the air cylinder. A plurality of corresponding cams on the second camshaft respectively correspond to the exhaust valve component of each power cylinder and the air cylinder. The invention has the advantages of compact structure, high energy utilization efficiency, good matching performance of the power part and the air part, less assistant equipments, longer service life, reliable performance, easy operation and no need of special staring equipment.

Description

technical field [0001] The invention relates to the field of mechanical design and manufacture, in particular to a self-driven integrated air compression equipment. Background technique [0002] High-pressure air sources are more and more widely used in industrial production and people's lives. Correspondingly, air compressors have become one of the most important equipment in production and construction units. For example, pneumatic equipment for mobile operations, production workshops, mines, mines and other places are inseparable from air compressors. [0003] At present, industrial air compressors mainly include piston air compressors, screw air compressors, centrifugal compressors, axial flow compressors (cascades), and scroll air compressors. Among them, piston air compressors (also known as reciprocating air compressors) and screw air compressors are the most widely used in industrial production and operations. [0004] No matter what kind of air compressor, there i...
