摘要： A method of attaching a rotor to a shaft is provided to obtain increased motor performance. The increased motor performance is obtained as a result of a high impedance gap that is formed between the rotor bars and the rotor core during the heat shrinking operation to attach the rotor to a shaft. In the heat shrinking operation, the rotor is heated to between 600-800 °F. At this temperature the aluminum in the rotor bars expands faster than the steel in the rotor core and causes a deforming or yielding of one or both of the materials. As a result of this deformation of the material, the cooling of the rotor results in the formation of a gap between the rotor bars and the rotor core that operates as a high impedance barrier between the rotor bars and rotor core.

摘要： A system and method of sizing an inner diameter (604) of the center bore (104) of a laminated rotor (300) is provided. The inner diameter d of the center bore (104) is determined by taking a series of measurements in the center bore (104) with an electronic gauge (710) and then analyzing the measurements to determine the acceptability of the rotor (300). The electronic gauge (710) is inserted into the center bore (104) of the rotor (300) and measurements of the inner diameter d of the center bore (104) are taken at a variety of different depths and positions using the electronic gauge (710). The measurements are then analyzed to determine if the rotor (300) is acceptable for use by evaluating the measurements with respect to a reference diameter and a depth in the center bore (104).

摘要： A two-stage reciprocating compressor is provided. The compressor includes a block with a single cylinder and associated single compression chamber and single piston. The compressor further includes a crankshaft. The crankshaft has an eccentric crankpin that is operatively connected to the piston. A reversible motor is provided to rotate the crankshaft in a forward direction and in a reverse direction. An eccentric cam is rotatably mounted on the eccentric crankpin. The eccentric cam is held stationary with respect to the crankpin when the crankshaft is rotating in the forward direction. When rotating in the forward direction, the crankshaft drives the piston at a full stroke between a bottom position and a top dead center position. The eccentric cam rotates with respect to the crankpin when the crankshaft is rotating in the reverse direction. When rotating in the reverse direction, the crankshaft drive the piston at a reduced stroke between an intermediate position and the top dead center position.

摘要： A compressor for providing automatic capacity modulation is disclosed. The compressor comprises a compression chamber (332), a compressing member (336), a reexpansion area (334), a flow passage (354), a valve member (356), and a biasing member (370). The flow passage (354) is in fluid communication with the compression chamber (332) and the reexpansion area (334). In one position, the valve member (356) permits flow through the flow passage (354) and in a second position it prevents flow. The valve member is subjected to a first operating condition of fluid on one side and a second operating condition of the fluid on the other side. The biasing member (370) exerts a biasing force on the valve member (356). When the first operating condition reaches a predetermined point relative to the second operating condition, the valve member moves and effects a change in the capacity of the compressor.

摘要： A compressor (12) with a capacity modulation system (10) includes a compression chamber (30), a rotatable shaft (20) within the compression chamber (30), and a roller (32) mounted on the shaft (20) in contact with a wall of the compression chamber (30). A re-expansion channel (46) adjacent to the compression chamber (30) has a first end forming a re-expansion port (48) in the wall of the compression chamber (30). A re-expansion chamber (50) is connected to the re-expansion channel (46). A valve (52) disposed in the re-expansion channel (46) is movable between a first position, in which the valve (52) allows fluid communication between the compression chamber (30) and the re-expansion chamber (50), and a second position, in which the valve (52) prevents fluid communication between the compression chamber (30) and the re-expansion chamber (50). The compressor (12) operates in a reduced capacity mode with the valve (52) in the first position, and in a full capacity mode with the valve (52) in the second position.

摘要： A pressure equalisation method and system (10) is provided for starting a compressor (2) while maintaining the compressor (2) at a high pressure and comprises a valve (28) and a bleed port (26). The compressor (2) has a compressor inlet (16) for receiving a fluid at a first pressure and a compressor outlet (20) for discharging the fluid at a second pressure, and is operable to compress the fluid from the first pressure to the second pressure. The valve (28) is proximate to and in fluid communication with the compressor outlet (209 and is movable to an open position when the compressor (2) is operating to allow the fluid at the second pressure to flow through the valve (28) and is movable to a closed position when the compressor (2) stops operating to prevent backflow of the fluid at the second pressure through the valve (28) toward the compressor inlet (16). The bleed port (26) is upstream of the valve (28) and in fluid communication with the compressor inlet (16) to equalise the pressure of the fluid contained in the compressor (2) when the compressor (2) stops operating.
