摘要： An air pump with internal automatic controller has a housing, and a low-pressure blower, a high-pressure blower, a first auto-stop controller and a second auto-stop controller mounted in the housing. The first auto-stop controller has a first casing, a first air pressure sensing film, a pushing element, a swing rod, a connecting rod, a rotation restricting element, a first micro switch, a rotational pressing rod, and a first turning button. With the low-pressure blower inflating an inflatable article with low pressure air, and with the first auto-stop controller stably and reliably controlling the low-pressure blower, the low-pressure blower stops working automatically. The first auto-stop controller has simplified structure and inflates the inflatable article without manual work, which is a great convenience to users.

摘要： A compressor includes a control unit and a model unit. The control unit determines at least two actuation values of at least two actuating elements of the compressor via a transmitted setpoint value of a parameter of the compressor from a characteristic diagram of the compressor or at least two corrected actuation values of the at least two actuating elements via a model-based theoretical setpoint value from the characteristic diagram of the compressor. The model unit determines a model-based theoretical state of the compressor via the actuation values or the corrected actuation values by using a state model of the compressor. The model-based theoretical state of the compressor is described at least with the model-based theoretical setpoint value of the parameter of the compressor. The control unit controls at least one of the actuating elements as a function of the corrected actuation value of this actuating element.

摘要： A combination cooling and heating fan structure includes an electronic device for controlling a driving device to drive a fan blade assembly to rotate within a first rotational speed range and thereby cause cold convection when the driving device is started alone. The electronic device includes a limiting module for limiting the driving device to rotate within a second rotational speed range, which is smaller than the first rotational speed range, when the driving device and a heating device are started at the same time. That is, when the driving device and the heating device are started simultaneously, the limiting module limits the driving device to rotate within the second rotational speed range for the fan blade assembly to blow hot air through an indoor environment and cause heat convection, which increases the temperature of the indoor environment while preventing quick loss of thermal energy during the heat convection.

摘要： A centrifugal compressor for compressing a refrigerant vapour in a refrigeration cycle. The compressor comprises an impeller drive shaft supported by first and second radial bearings for rotation within the compressor housing and an impeller assembly including at least one centrifugal impeller wheel mounted on the impeller drive shaft to rotate with the impeller drive shaft. The first and second radial bearings are hydrodynamic fluid bearings in which the bearing fluid is the refrigerant vapour.

摘要： A centrifugal compressor 200 used in a gas pipeline 1 has a centrifugal impeller provided with a hub and a plurality of blades. The blade angle distribution of the blade is configured such that a hub side blade angle is maximum on the side closer to a hub side leading edge than a central point of a hub side camber line, and from this part to the hub side leading edge, a hub side blade angle distribution curve is convex in a blade angle increasing direction. Further, the blade angle distribution is configured such that a counter-hub side blade angle is minimum at a counter-hub side leading edge of the counter-hub side camber line, or on the side closer to the counter-hub side leading edge than a central point of a counter-hub side camber line, and in an arbitrary section of the counter-hub side blade angle distribution curve including a part where the blade angle is minimum, the counter-hub side blade angle distribution curve is convex in a small blade angle direction, and in a section from the downstream side of the section where the counter-hub side blade angle distribution curve is convex to the counter-hub side trailing edge, the counter-hub side blade angle distribution curve is convex in a large blade angle direction. With this arrangement, it is possible to obtain a gas pipeline centrifugal compressor in which the low flow-rate side operating range is expanded and a high flow-rate side operating range is maintained.

摘要： A rotary adjustment controller of an air pump has a casing, a micro switch, an air pressure sensing film, and a control mechanism. The control mechanism has a bolt, a nut, and a turning button. The nut is screwed on the bolt. The micro switch is securely mounted on and moves along with the nut. The turning button selectively drives the bolt to rotate. With turning the turning button to rotate the bolt, the micro switch selectively departs from or approaches the air pressure sensing film. Positions of the micro switch are adjusted steplessly, so an inflatable article can be inflated to a desired hardness. The rotary adjustment controller has simplified structure and can be operated conveniently and rapidly.
