Abstract: A method and apparatus for analyzing the operating condition of a machine, such as a reciprocating compressor (10), is provided. The method comprises testing for fluid flow across the closed suction and discharge valves (30-33), as well as leakage across the piston (16), when the machine is in a non-operating condition. The test apparatus may be removable attached externally to the machine by connection to the Kiene head end indicator cock (22) and the crank end indicator cock (24) or the apparatus may be built in internally of the machine.

Abstract: The invention relates to an improved reciprocating pump providing oil for low pressure, self-contained oil-filled cables. it is particularly important to have a gas tight system in such a pumping plant since the oil in the storage tank (6) has to be kept under vacuum at all times to keep the oil in a gas-free condition. The air or gas driven oil pump (8) has two piston rod seals (9,10). The area between the two seals is provided with an inlet (11) and outlet opening (12) through which oil can be flushed from the high pressure side of the pump (8) to the top of a storage tank (6).

Abstract: A pump, characterized by flexible tubes which are cyclically expanded and contracted to cause fluid to be pumped, comprises a pair of liquid filled cylinders each containing a flexible tube connected to inlet and outlet valves, a liquid filled control cylinder communicating at its opposite ends with respective ones of said pump cylinders, and a piston reciprocable in said control cylinder for alternately transferring fluid to and from said pump cylinders for alternately and cyclically expanding and contracting said tubes to cause fluid to be pumped in a double acting pump action. The pump is especially well suited for pumping abrasive and corrosive slurries, heavily pigmented and/or metal filled coating materials and the like. The pump is characterized by improved piston means, improved sealing and retaining means for both the piston and the tubes, and means for detecting leakage across the piston, whereby to increase pump reliability and longevity of service, and to monitor internal pump conditions.The basic objective is a pump design providing both perfect vacuum retention and perfect pressure retention, as well as miniscule liquid leakage, over millions of cycles of pump operation.

Abstract: A dynamic compressor control is provided. The dynamic compressor control includes sensors to sense operating parameters of a compressor and a compressor analytic software package. The compressor analytic software package uses the sensed operating parameters of the compressor to generate key performance indicators. The key performance indicators are used to calculate process variables for the compressor. The dynamic compressor control uses the sensed operating parameters and the process variables calculated from the key performance indicators to provide operating alarms and/or shutdowns.

Abstract: Presented herein are systems and methods for attenuating flow ripple generated by a hydraulic pump. In certain aspects, a method and system for operating a hydraulic positive displacement pump according to a stabilized command profile are disclosed, such that flow ripple generated by operation of the pump according to the stabilized command profile is attenuated as compared to operation of the pump according to a corresponding nominal command profile. In other aspects, a pressure-balanced active buffer is disclosed that allow for at least partially cancelling flow ripple in a hydraulic circuit comprising a pump. In another aspect, a method for generating ripple maps for a pump is disclosed. Such ripple maps may be used, for example, to determine the stabilized command profile used to operate the pump, or may be used by the pressure-balanced active buffer to counteract ripple in the hydraulic circuit.

Abstract: The present application discloses a compressor including a crank shaft, a first reciprocation converter, a first cylinder body, a first pressurizing portion, a second reciprocation converter, which is connected to the crank shaft with a phase different by 180 degrees from the first reciprocation converter, a second cylinder body, a second pressurizing portion, and a connecting portion configured to interconnect the compression chambers. The compression chambers are arranged so that a timing at which the gas is discharged from a specific compression chamber among the compression chambers becomes the same as a timing at which the discharged gas is suctioned into another compression chamber at a higher side by one stage than the specific compression chamber.

Abstract: A sealing system for a pump having a plunger includes a housing having an internal chamber adapted to receive a portion of the plunger. Primary and secondary seals are located within the internal chamber and adapted to sealingly engage the plunger. The primary seal communicates with the fluid being pumped. A barrier fluid chamber contains a barrier fluid in contact with the primary seal and the secondary seal. A pressure referencing device has an inlet port in communication with the pumped fluid and an outlet port providing fluid at a pressure magnitude equal to a peak pressure of the pumped fluid. A pressurizing device is in communication with the fluid at the peak pressure and the barrier fluid to maintain the barrier fluid pressure at a magnitude greater than the peak pressure of the pumped fluid such that the pumped fluid is restricted from leaking past the primary seal.

Abstract: A high pressure fuel pump includes a cylinder having a pressurizing chamber and a plunger inserted into the cylinder. The plunger is axially reciprocated by a lifter to pressurize fuel in the pressurizing chamber. A seal member encompasses a portion of the plunger that is projected from the cylinder. The seal member disconnects a cylinder side space surrounded by the seal member from a lifter side space outside the seal member. The seal member has an annular lip portion that contacts a peripheral surface of the plunger, and the annular lip portion has a pair of lips separated from each other in an axial direction of the plunger. An axial distance between the lips is greater than a stroke of the plunger. As a result, fuel does not enter the lifter side space, and lubricating oil does not enter the cylinder side space.
