A Russian developer (the company name is not disclosed in accordance with the Decree of the Government of the Russian Federation) has received a patent for an improved piston compressor for the oil and gas industry. The new design increases equipment efficiency by balancing the crossheads — moving parts connecting the piston to the rod.
The essence of the development lies in changing the design of the lock nut on the rod. Its mass is at least 40% of the crosshead's mass, and the nut itself is made round with radial holes. This allows balancing the loads inside the compressor, reducing vibrations, and decreasing wear on parts.
Russian engineers improve compressor equipment
Previously, a group of Russian inventors patented a free-piston compressor with an electromagnetic drive — a magnetic piston moves inside a cylindrical body, and a special ratio of magnets and inductor windings allows for increased efficiency and improved flow characteristics. The development is intended for use in refrigeration technology and pneumatic systems.
Reduced vibrations and increased reliability are also at the core of the design of the rotary-piston engine by Moscow engineer Oleg Butenko: there, the key role was played by a ratchet mechanism with intermittent rotor rotation. The author envisioned the possibility of applying the scheme not only in internal combustion engines but also in compressors.
