HI-SEA MARINE successfully delivered 1 Sets of marine air compressor to USA. Marine air compressors are mainly used for the start of maine enginel, the start and stop of hydropower equipment and gas resource in pressure can also be used as gas resource in pressure vessel check, instrument check, pneumatic device, building, petrochemical area and plastic area ,etc. The cooling method of are air cooling and water cooling. In general, the marine air compressor is powered by the electric motor, while the emergency air compressor is powered by the diesel engine.

The main parameters are as follows:

u Model: CZF-20.4/3-C

u Type: double vertical, two-stage compression, piston type

u Displacement: 20.4m³/ h (0.34m³/min)

u Rated pressure: 3.0 Mpa

u Speed: 600r/mim

u Motor power: 5.5 KW-4 pole

u Electric system: 380V/3P/50HZ

u Configuration: air compressor, electric motor, pressure controller, electric control box, solenoid valve, etc. (automatic start, automatic stop, automatic alarm and other functions).

The drawing is as follows:

 

This unit of production CZF-20.4/3-C (the original 2ZF-0.34/3-B)type medium voltage type piston air compressor has a long history, reliable performance, stable quality, product technical performance indexes of domestic advanced level, sell well in the whole country, supporting exports, enjoying high reputation in Chinese market.

Air compressor is structured as two stages, single acting, Piston type. F stands for wind cooling. S stands for water cooling. The structures of air compressors are shown in drawing.

The running mechanism of the crank and connecting rod is used for the air compressor. The crankshaft is installed in two rolling bearings in the crankcase. The belt pulley is installed on the left of the crankshaft. The first and second-stage cylinders are positioned by flanges and installed side by side on the crankcase. The bottom end of the connecting rod is in “Ha Fu” form. The form. The connecting rods are tightly fixed together .with the connecting rod screw. The connecting rods are connected by a piston pin. On each stage piston, a different number of piston rings are fitted for sealing, and at the same time, oil rings and scraper rings are also fitted for collecting the spare lubricating oil on the cylinder wall and sending it back to the crankcase. Each stage valves are all the ring valves or combination valve which can open automatically with the change of pressure. The safety valves and control valves are spring-controlled.

The crankshaft of the air compressor is driven by a motor or diesel engine through a belt pulley, and the rotation of the crankshaft is transformed into a reciprocating motion of the piston in the cylinder by means of a connecting rod. The compressed air in the first stage cools through the cooler, then is pressed by the second stage to rated pressure, entering the gas bottle.

Before start production, HI-SEA MARINE sent the drawings to clients for confirmation. After finished the Marine Air Compressor, the quality department and technical department carried out all kind of tests. After that the CCS surveyor also carried out all tests. All the test of the air compressor meet the expected design standards and the rules of CCS. 

Faced with the complex process of cross-border transportation, the HI-SEA supply chain team collaborates with logistics partners to tailor efficient and safe transportation solutions. From packaging protection, customs declaration to sea freight tracking, seamless connection was achieved throughout the entire process, and finally arrived at the destination on time, winning high praise from customers.
