Air compressor
Detailed introduction:

The product is mainly used for starting marine diesel engine, starting and braking of water and electricity equipment, and supplying air source. It can also be used for pressure vessel detection, instrument detection, pneumatic device, construction, petrochemical, plastic and other fields as pressure air source.

The product can be equipped with gas control device, electric control device or automatic control device. It can provide single machine, motor driven horizontal unit, vertical unit and gas cylinder unit. It can also provide diesel driven horizontal unit and gas cylinder unit.

Technical parameters of air compressor

Structure and working principle

The compressor is double stage, single acting, piston type. F for air cooling, s for water cooling.

The compressor adopts crankshaft connecting rod mechanism. The crankshaft is installed on the rolling bearings at both ends of the crankcase, and the belt pulley is installed at the left end of the shaft. Class I cylinder and class II cylinder are installed on the crankcase with flange positioning. The big end of the connecting rod is Haff type and fixed with connecting rod screws. The connecting rod is connected with the piston through the piston pin. A certain number of gas rings are installed on the pistons at all levels for sealing. At the same time, oil rings and oil scraping rings are installed to lubricate and collect the excess lubricating oil on the cylinder wall and return it to the crankcase. The air valves at all levels are ring valve, tongue spring valve or combination valve which can open and close automatically with the change of pressure. The safety valve and control valve are spring regulated. The motor or diesel engine drives the crankshaft to rotate through the belt pulley, the crank pin of the crankshaft drives the big end of the connecting rod to rotate, and the small end of the connecting rod drives the piston to reciprocate in the cylinder through the piston pin. Class I compressed air is cooled by interstage cooler, and then compressed to rated pressure by class II before entering the cylinder.

The gas cylinder unit is composed of mobile gas cylinder, compressor, B-type V-belt and motor or diesel engine. The compressed air enters the cylinder through the check valve. The pressure of the gas in the cylinder is indicated by the pressure gauge. When the compressed air exceeds the set pressure, the control valve, safety valve or pressure control device work successively.
