摘要： A module for a vacuum pumping and/or abatement system. The module comprises a frame defining a space, a plurality of facilities inputs configured to receive facilities from a facilities supply, a plurality of facilities outputs configured to output the received facilities out of the module, and a plurality of facilities connection lines located at least partially within the space defined by the frame. The plurality of facilities connection lines connect the facilities inputs to the facilities outputs. The module further comprises a controller configured to control supply of facilities received at the facilities inputs out of the facilities outputs; and control operation of one or more vacuum pumping and/or abatement apparatuses remote from the module.

摘要： A compressor module includes: a rotational driving machine having an output shaft which is rotationally driven around an axis; a compressor which is disposed so as to be adjacent to the rotational driving machine in an axial direction in which the axis extends; a base plate which supports the rotational driving machine and the compressor from below in a vertical direction; and a storage tank which is configured to store a lubricating oil used in the rotational driving machine and the compressor. The storage tank has a tubular tank main body that is provided on an outer side of the base plate in a width direction and extends in a direction including the axial direction.

摘要： A linear compressor includes a cylinder, a piston disposed in the cylinder and reciprocating along an axis of the cylinder, a stator core disposed outside the cylinder, a coil winding body that is disposed in the stator core and includes first to fourth coils that are spaced from each other in a circumferential direction, a mover connected to the piston and reciprocating along the axis by an electromagnetic interaction with the coil winding body, and a switch unit configured to connect the first and second coils and the third and fourth coils in series or in parallel depending on a magnitude of a load. The first and second coils are connected in series, and the third and fourth coils are connected in series. The first to fourth coils each have the same inductance.

摘要： The purpose of the present invention is: to enable hot water at a required temperature to be supplied, even in cases when compressor load factor is low; to suppress heat dissipation from a waste-heat recovery device; and to improve waste-heat recovery rate. A waste-heat recovery system in an oil-cooled gas compressor is provided with: a compressor main body (3); an oil separator (6); gas piping (8) which supplies, to a demanded destination, compressed gas separated from oil by the oil separator; oil piping (7) which returns, to the compressor main body, the oil separated by the oil separator; and a waste-heat-recovery heat exchanger (10) which recovers heat from the compressed gas and/or the oil. The waste-heat recovery system is also provided with: a hot-water storage tank (19); circulation circuits (17, 18) in which a heat medium is made to circulate between the waste-heat recovery heat exchanger and the hot-water storage tank; a circulation pump (22) provided to these circulation circuits; and a control device (32) which, in cases when the temperature of the oil or the compressed gas subjected to heat exchange in the waste-heat-recovery heat exchanger is equal to or less than the temperature of the hot water in the hot-water storage tank, stops the circulation pump or reduces the rotational frequency of the circulation pump.

摘要： A pump trailer including a frame, a pump and at least one locomotion member. The pump is suspended within the frame using an elevator. The at least one locomotion member is coupled to a base of the frame to facilitate motion of the frame over terrain. The elevator raises the pump to a fully raised position or lowers the pump to a pumping position.

摘要： A system and method for boosting the pressure of a low-pressure multiphase mixture into a high-pressure multiphase mixture. The system includes a gas-liquid separator, a liquids pump and a liquid piston compressor. The method includes introducing the low-pressure multiphase mixture into the pressure boost system, operating such that a low-pressure liquid and a low-pressure gas form, boosting the pressure of the low-pressure liquid to a high-pressure liquid, introducing low-pressure gas during a charging period into the liquid piston compressor, converting the low-pressure gas into high-pressure gas using the high-pressure liquid during a compression period, discharging the high-pressure gas form the liquid piston compressor, and mixing the high-pressure liquid and gas such that the high-pressure multiphase mixture.

摘要： A system can include an actuator with a piston rod that displaces in response to pressure in the actuator, a seal assembly that seals about the piston rod and includes seal cartridges, each including a dynamic seal sealingly engaging the rod, and each including a static seal sealingly engaging a seal assembly housing, and a port providing communication between a housing exterior and a housing interior between adjacent static seals. A method can include preventing leakage from a well with a seal assembly about a piston rod of a hydraulic actuator, the seal assembly including seal cartridges, each including a dynamic seal that sealingly engages the rod, and each including a static seal that sealingly engages a seal assembly housing, enabling communication through a housing sidewall to a housing interior between adjacent static seals, and reciprocably displacing the rod in response to pressure variations in the actuator.

摘要： A method and device for testing the output pressure of a compressed air unit is disclosed. A pressure verification device includes a first port configured for attachment to a compressed air unit. A first pressure relief valve is connected to a second port of the pressure verification device and is set to open at a first set pressure. A switching valve is connected to a third port. When the pressure is at least the first set pressure, a path to atmosphere is established from the first port through the first pressure relief valve when the switching valve is in the closed position. In addition, the first pressure relief valve comprises a means for at least one of an audible, a tactile and a visual indicator of the operation of the compressed air unit.
