| 41 | Compensated barrier and lubrication fluids pressure regulation system for a subsea motor and pump module | US13806532 | 2011-06-20 | US09435330B2 | 2016-09-06 | Ole Petter Tomter |
| A compensated barrier and lubrication fluids pressure regulation system for a subsea motor and pump module is disclosed. The system comprises a hydraulic fluid supply, a barrier fluid circuit, and a lubrication fluid circuit. Hydraulic fluid in the barrier fluid circuit is pre-tensioned towards a motor by a first separating pressure compensator which is responsive to the pressure in the lubrication fluid circuit and which applies the sum of the pressure in the lubrication fluid circuit and an inherent pre-tensioning pressure to the barrier fluid circuit. Hydraulic fluid in the lubrication fluid circuit is pre-tensioned towards a pump by a second separating pressure compensator which is responsive to a pumped medium pressure at a suction side or at a discharge side of the pump and which applies the sum of the pumped medium pressure and an inherent pre-tensioning pressure to the lubrication fluid circuit. | ||||||

| PROBLEM TO BE SOLVED: To prevent refrigerating-machine oil from flowing out of the compressor, to supply oil in an oil-retention chamber to a sliding-part of a bearing, and decrease the amount of move out, in a horizontal scroll compressor. SOLUTION: In the horizontal scroll compressor, compressed gas is discharged from a discharge pipe provided to a hermetic-vessel holding a compressor mechanism and an electric motor part. The inside of the hermetic vessel is separated by a supporting board into a first space holding the compressor mechanism and the electric motor part, and a second space provided with the discharge pipe. A communication path is provided below the supporting board so as to allow the bottom of the first space to communicate with the space upper than the driving shaft in the second space. In the case of high-speed operation where difference in oil levels is increased, the oil levels are adjusted through the communication path. In order to stabilize the oil supply to oil the bearing, the oil is supplied by an oil pump placed at the end of the drive shaft near the oil-retention chamber. COPYRIGHT: (C)2008,JPO&INPIT | ||||||

| PURPOSE: To operate a cooling system in an optimum state by easily monitoring the surface level of a coolant in the system by subtracting the measured temperature of the coolant from the corresponding temperature related to the characteristic function of the coolant with respect to the measured pressure of the coolant, and detecting the undercooling of the coolant from the subtracted result. CONSTITUTION: The cooling circuit of a cooling system 1 is constituted of a compressor 1.1, a condenser 1.2, a liquid container with a drier 1.3, an injection valve 1.4, and an evaporator 1.5. A pressure sensor 3 and a temperature sensor 2 are installed to the coolant/high-pressure liquid pipeline 1.2.1 between the condenser 1.2 and drier 1.3. The sensors 2 and 3 are connected to a monitor 4 respectively through signal lines 2.1 and 3.1. The monitor 4 is constituted of a storage device 4.1, a subtractor 4.2, and a switch device 4.3. The measured temperature of a coolant is subtracted from the corresponding temperature related to the characteristic function of the coolant with respect to the measured pressure of the coolant. Then the undercooling of the coollant is detected from the subtracted result and evaluated as the magnitude of the surface level of the coolant. | ||||||

| A fluid machine (101) includes a first compressor (107) and a second compressor (108). The first compressor (107) has a first closed casing (111), a first compression mechanism (102a), an expansion mechanism (104), and a shaft (113). A first oil reservoir (112) is formed in the first closed casing (111). The second compressor (108) has a second closed casing (125) and a second compression mechanism (102b). A second oil reservoir (126) is formed at a bottom portion in the second closed casing (125). The first closed casing (111) and the second closed casing (125) are connected to each other by an oil passage (109) so that a lubricating oil can flow between the first oil reservoir (112) and the second oil reservoir (126). An opening (109a) of the oil passage (109) on a side of the first closed casing (111) is located above the expansion mechanism (104) with respect to the vertical direction. This configuration prevents the high temperature lubricating oil in a surrounding space of the expansion mechanism (104) and the high temperature lubricating oil in the second compressor (108) from flowing. Thereby, the heat transfer between the first compressor (107) and the second compressor (108) is suppressed. | ||||||
