| An oil pump system includes an oil pump, a first hydraulic passage, a second hydraulic passage, a return hydraulic passage, and a control valve. When a revolving speed of a rotor of the oil pump is low, and when a hydraulic pressure of a hydraulic oil, discharged out of a first outlet port of the oil pump to the first hydraulic passage, is lower than a predetermined value, a valve body of the control valve is placed at a first position, thereby joining the hydraulic oil, flowing in the first hydraulic passage, with the hydraulic oil, discharged out of a second outlet port of the oil pump to the second hydraulic passage, and delivering the thus joined hydraulic oil to a hydraulic oil receiving unit via a hydraulic-oil-delivery passage. When the revolving speed of the rotor is high, and when the hydraulic pressure of the hydraulic oil, discharged out of the first outlet port to the first hydraulic passage, is higher than the predetermined value, the valve body is placed at a second position, thereby inhibiting the hydraulic oil from joining, and delivering only the hydraulic oil, discharged out of the first outlet port to the first hydraulic passage, to the aforementioned destination. The oil pump system is downsized and lightweighted advantageously, and is improved in terms of work efficiency and on-boardability. | ||||||

| A screw compressor is for use of a screw chiller, and comprises a pair of screw rotors and a casing housing the screw rotors, a capacity control valve for varying a ratio of volume, a motor for driving the screw rotors and an inverter for varying the rotational speed of the motor. The screw compressor is controlled using rotational speed control means by the inverter and mechanical capacity control means by the capacity control valve independently or combined together according to loads. The maximum efficient point in a capacity control performed solely by the inverter is set to a rotational speed side lower than the rated operation point. In a region where the rotational speed is higher than the maximum efficient point, the inverter solely takes control from a rated rotational speed to a high rotational speed side. | ||||||

| PURPOSE: To achieve a less than full capacity operation by reducing an effective length of rotatable rotors, selecting either one of a signal air pressure from an internal pressure control regulator or an external input control device to send a control signal to a reducing means. CONSTITUTION: A nitrogen gas is extracted by operating at full capacity an air compressor 40 provided with a sliding port which controls rotatable rotors for compressing air and by sending the resultant to an air separation device 50 through a cleaner 48. When an external signal is inputted, the external input control device 58 amplifies the external signal input to transmit it to a transducer 56. An adjusted air pressure from a line regulator 54 is passed through a selecting relay 60 according to the size of a signal and sent to the sliding port and an actuator 42 with the selecting relay 60 designed to select an external pressure signal. The sliding port is operated to reduce an effective length of the rotors, to decrease the compressor 40 operating level to less than full capacity and to reduce flow rate of the resulting product.

| A compressor system including a lubricant inlet compresses a gas and discharges a mixed flow of compressed gas and lubricant. A valve housing includes a hot and a cooled lubricant inlet, and a lubricant outlet. A sleeve is disposed within the valve housing and is movable between a first and a second position. The sleeve defines a mixing chamber and includes a first aperture with the hot lubricant inlet and a second aperture with the cooled lubricant inlet. The hot and cooled lubricant mix in the mixing chamber are directed to the lubricant inlet of the compressor. A thermal element is positioned to sense a temperature and moves the sleeve in response. The movement of the sleeve varies the amount of hot lubricant admitted through the first aperture and varies the amount of cooled lubricant admitted through the second aperture to control a lubricant temperature. | ||||||
| 39 | Liquid ring vacuum pump with cavitation regulation | US14364083 | 2012-12-12 | US09169838B2 | 2015-10-27 | Heiner Kösters; Matthias Tamm; Daniel Schütze |
| A method for operating a liquid ring vacuum pump employs taking vibration measurements of the pump and comparing the measurements with a prescribed cavitation threshold. In addition, a measurement representing the liquid content in the gas to be conveyed is taken. This measurement is compared with a prescribed threshold. The rotational speed of the liquid ring vacuum pump is reduced if the prescribed cavitation threshold has been exceeded and the liquid content is less than the prescribed threshold. The rotational speed is increased if the prescribed cavitation threshold has been exceeded and the liquid content is greater than the prescribed threshold. A liquid ring vacuum pump is designed for implementing the method. Due to the regulation depending on the oscillations of the pump, the pump can be operated near the cavitation boundary without any risk of damage. | ||||||
