Background
The compressor is mainly used for compressing low-pressure gas into high-pressure gas, wherein the reciprocating piston compressor has a wide pressure increasing range, and the mechanical reciprocating piston compressor used in the current market has a wide market application field, such as: the compressor is used in the fields of gas pressurization, such as an inflating pump, a natural gas pressurization conveying station, a natural gas filling station, the chemical industry, an emptying natural gas recovery station, the engineering field, the medical field and the like;
the piston compressor used in the market converts rotary motion into reciprocating linear motion of a piston to enable the piston to form a compression process of gas in a cylinder, the main structure is that a motor drives the rotary motion of a connecting rod connected with a crankshaft supported in a crankcase to convert into linear motion through connecting a crosshead, the crosshead is connected with a piston rod of the piston rod and is provided with a piston body, so that the piston can realize reciprocating motion in the cylinder to perform the compression process of the gas, and the gas in the cylinder is sealed by filling materials to prevent the gas from leaking from the piston rod to achieve the compression process and the sealing process of the gas; the basic requirements of a compressor for oil and gas fields generally fall into five aspects: the requirement is suitable for the gas quality requirement of natural gas, and the method is specially designed for the oil and gas field process; strong variable working condition adaptability is required; the variety is required to be normalized and serialized; the installation and the operation and maintenance are required to be convenient; continuous operation and high reliability are required.
The compressor piston assembly comprises a piston body, a piston rod, a piston ring, a supporting ring and the like. Different piston structures and materials are available for cylinders with different cylinder diameters, different working pressures, different working media, whether oil is injected or not, and the like.
For the cylinder with larger cylinder diameter, a welded piston body structure is generally adopted; for the cylinder with the medium cylinder diameter, a cast piston body is adopted; for the cylinder with small cylinder diameter, more forgings can be selected.
According to different working media, working pressure and working temperature, the die is designed into a casting structure or a forging structure according to actual working requirements. Regardless of the structure, the valve has a wide valve chamber and an air chamber.
The cylinder is made of high-strength gray cast iron, nodular cast iron or forged steel according to the working pressure.
