摘要： Mechanical overloads in a reciprocating gas compressor can cause irreparable damage to compressor components if the source of the overloads is not repaired. A method of detecting mechanical overloads includes applying an overload indicator across an interface between components in the compressor, and observing a mechanical condition of the overload indicator. The mechanical condition of the overload indicator is indicative of whether the compressor experienced a mechanical overload. By placing the indicator in an appropriate location in the compressor, overload conditions can be checked during routine inspections and maintenance checks.

摘要： Mechanical overloads in a reciprocating gas compressor can cause irreparable damage to compressor components if the source of the overloads is not repaired. A method of detecting mechanical overloads includes forming a mechanical fuse that is configured to strain under overload conditions, and observing a condition of the mechanical fuse. The condition of the mechanical fuse is indicative of whether the compressor experienced a mechanical overload. By simply observing the mechanical fuse, overload conditions can be checked during routine inspections and maintenance checks.

摘要： A method of determining fuse parameters in a reciprocating gas compressor ensures a safe failure upon exceeding an overload limit. Stresses and bolted joint behavior for critical components in compressor running gear are evaluated using a finite element analysis. Capabilities of the critical components during an overload event are evaluated using a propagation and variances tool. The capabilities of the critical components are compared against overload conditions. At least one of an optimal fuse location and a fuse geometry are determined according to the comparison to establish a safe failure point upon exceeding the overload limit. With a mechanical fuse defining a failure point, critical compressor components can be protected from damage, and personnel can be protected from risk of a gas leakage.

摘要： Crank gear (10) for a reciprocating compressor of the type equipped with at least one module which has two lines with two opposite cylinders. The crank gear is suitable for constraining the two cylinders to a crankshaft (20), so as to align the two cylinders, opposite each other with respect to an axis (21) of the shaft (20). The crank gear (10) is equipped with two rods (35), a series of connecting rods (30) and two cross heads (40) and (50). The series of identical connecting rods (30) is symmetrically positioned with respect to the alignment axis (25) of the two cylinders and furthermore the overall barycentre of the series of connecting rods lies on the axis (25) and on the axis (21) of the shaft (20) so that the whole of the shaft (20) is both statically and dynamically balanced.
