The crankshaft drives the connecting rod, and the connecting rod drives the piston, which moves up and down. The movement of the piston changes the volume in the cylinder. When the piston moves downward, the cylinder volume increases, the intake valve opens, the exhaust valve closes, and air is sucked in to complete the intake process; when the piston moves upward, the cylinder volume decreases, the exhaust valve opens, and the intake valve closes to complete the compression process. Usually there are piston rings on the piston to seal the gap between the cylinder and the piston, and there is lubricating oil in the cylinder to lubricate the piston ring.
A positive displacement compressor that relies on one or more reciprocating pistons to change the internal volume of the compression chamber.
At present, reciprocating compressors are mainly piston air compressors, chemical process compressors, oil and natural gas compressors, and piston air compressors are now mainly developing in the direction of medium and high pressure, which is a height that screw machines and centrifuges cannot currently reach.
Adaptive two-stage compression process: within the intake pressure range of 3-20MPa, there is no need to switch the compression stages, and it automatically adapts to the normal operation of the two-stage compression, eliminating the impact of drastic changes in gas volume caused by switching the compression stages, and running smoothly. The average gas volume is increased by 30%-50% at the same motor power, and the motor power is allowed to be reduced by 25%6-30% at the same average gas volume;
Adapt to different filling needs: the unit has direct charging and programmable charging functions;
Multifunctional safety soundproof room: with sound insulation, silencing, rain protection, heating and heat preservation functions, with maintenance space and lifting devices, explosion-proof lighting, ventilation, gas leak alarm and other functions, the soundproof room has an escapeable safety door to ensure the safety of equipment and personnel;
Fully automatic pneumatic instrument: the instrument wind for fully automatic pneumatic actuators can use compressed air or natural gas according to user requirements, and take corresponding safety measures;
Easy maintenance and low operating cost: The cylinder, piston structure and valve structure dimensions of each column of reciprocating compressor are exactly the same, which reduces the variety of vulnerable parts, reduces maintenance costs and reduces operating costs. It has the characteristics of wide intake pressure range, large gas volume, high degree of automation, high efficiency and energy saving.
Good running balance performance: two rows of horizontal symmetrical balanced units, with crank angles of 180°, balanced inertia force and uniform piston force distribution;
Excellent overall rigidity of the machine body: the whole machine body is designed by finite element analysis software to simulate the motion load of the compressor, and the machine body and the middle body can adopt an integrated structure; Lubricating oil level gauge: it can be equipped with clamp thermal resistors and electric heaters to detect oil temperature and oil level, and can be interlocked with the operation of the unit;
Convenient inspection and maintenance: the machine body is equipped with windows for disassembly and inspection of crossheads, etc.;
Pre-lubricating oil mask: it can force pre-lubrication of moving parts to ensure reliable operation;
Wide range of application: D-type machine can adapt to the needs of substations, mother stations and standard stations according to different models.
