摘要： This heat pump and dehumidifying apparatus have small energy-consumed per moisture-removed ratios. Their components include a pressurizer for raising refrigerant pressure; a condenser for condensing refrigerant, thereby heating a high-temperature heat source fluid; an evaporator for evaporating refrigerant to cool a low-temperature heat source fluid; and a heat exchanger in a refrigerant path connecting the condenser and the evaporator for evaporating and condensing refrigerant under an intermediate pressure between the condensor pressure and the evaporator pressure. The low-temperature heat source fluid is successively cooled by the heat exchanger, cooled by the evaporator, and heated by the heat exchanger. This fluid can be precooled by the heat exchanger before cooling in the evaporator, and heat removed during precooling can be returned to the fluid after cooling by the evaporator.

摘要： A dehumidifying apparatus capable of continuously supplying dry air having an absolute humidity of 4 g/kgDA or lower is provided. The dehumidifying apparatus has a moisture adsorbing device for removing moisture from process air and for being regenerated by desorbing moisture therefrom with regeneration air B, and a heat pump having a condenser for condensing a refrigerant to heat the regeneration air at the upstream side of the moisture adsorbing device, an evaporator for evaporating the refrigerant to cool the regeneration air to a temperature equal to or lower than its dew point at the downstream side of the moisture adsorbing device, a pressurizer for raising a pressure of the refrigerant evaporated by the evaporator and delivering the refrigerant to the condenser, and a heat exchanger for exchanging heat between the regeneration air flowing between the moisture adsorbing device and the evaporator and the regeneration air flowing between the evaporator and the condenser, wherein said regeneration air is used in circulation. Since moisture is removed from the process air by the moisture adsorbing device, it is possible to obtain air having a low dew point equal to or lower than an freezing point, i.e., a low absolute humidity of 4 g/kgDA or lower.

摘要： A turbomachine having variable angle diffuser vanes is demonstrated with the use of a centrifugal pump. The performance of a diffuser is enhanced greatly by the use of adjustable angle diffuser vanes which can be set to a wide range of vane angles to provide a variable size of an opening between adjacent vanes. The demonstrated pumping system has a significantly wider operating range than that in conventional pumping systems over a wide flow rate, and is particularly effective in the low flow range in which known diffuser vane arrangements would lead to surge in the entire system and other serious operational problems. A number of examples and formulae are given to demonstrate the computational methods used to select a vane angle for a given set of operating conditions of the turbomachine.

摘要： Driven turbomachinery for use in centrifugal and mixed flow pump overcomes operational for overcoming difficulties, such as flow separation and generation of surge at low flow rates, often encountered in similar machines of the conventional design. The turbomachinery is provided with variable-angle inlet guide vane and variable-angle diffuser vanes, and the diffuser section is constructed according to a fluid dynamic principle, and the vanes having a wing shape are distributed tangentially so that the diffuser section acts as a centrifugal diffuser. A convenient operational parameter, chosen from such variables as input current to the drive motor, rotational speed or torque of the drive motor, inlet/exit pressures, and fluid velocity, is monitored during the operation by means of sensors strategically attached to parts of the operating system. Real-time changes in the operating parameter is measured and the setting angle of the inlet guide vane is adjusted in accordance with a predetermined relation between inlet flow volume rates and flow angle of the fluid exiting from the impeller so as to maintain the fluctuations in the monitored operating parameter below a threshold value. If the targeted head value is not produced under this adjustment, the setting angle of the diffuser vanes can also be adjusted based on real-time measurements of other operational parameters. If this adjustment fails to produce the targeted head value, then the rotational speed of the impeller can be adjusted to operate the system while avoiding surge and other problems encountered at flow rates.
摘要翻译：用于离心和混流泵的驱动涡轮机械克服了克服困难的操作，例如在常规设计的类似机器中经常遇到的流量分离和在低流量下产生浪涌。涡轮机械设有可变角入口引导叶片和可变角度扩散器叶片，并且扩散器部分根据流体动力学原理构造，并且具有翼形的叶片切向分布，使得扩散器部分用作离心扩散器在操作期间通过策略性地附接到驱动马达的部分的传感器来监测从诸如驱动马达的输入电流，驱动马达的转速或转矩，入口/出口压力和流体速度等变量中选择的便利的操作参数操作系统。测量操作参数的实时变化，并且根据入口流量与从叶轮离开的流体的流动角度之间的预定关系来调整入口导流叶片的设定角度，以保持入口导叶的波动监控操作参数低于阈值。如果在该调整下不产生目标头值，则也可以基于其他操作参数的实时测量来调整扩散器叶片的设定角度。如果该调整不能产生目标头值，则可以调整叶轮的转速以操作系统，同时避免浪涌和其他在流速下遇到的问题。

摘要： A solids-liquid separator comprises a basin in which liquid containing solids is introduced from an inlet port of the basin in a direction tangential to the side wall of the basin so as to produce a swirling flow of the liquid. The swirling flow also generates a secondary flow, and both flows promote the floating of floatable solids on the surface and the settling of settlable solids on the bottom. The solids floating on the surface are discharged by the overflowing liquid and the settled solids are discharged through a discharge pipe opening at the bottom of the basin. The liquid from which solids are separated is discharged outwardly from an outflow opening of the basin independent from the discharge of solids. The inlet port and outflow opening are separated circumferentially with respect to the flowing direction so that the circumferential separation thereof subtends at least 180 degrees about the center of the basin.
