    摘要： The present application provides a centrifugal compressor for a refrigeration system and a refrigeration system. The centrifugal compressor has a reverse braking function and comprises: a rotor shaft; a compressor impeller connected to the rotor shaft; a brake component on the rotor shaft, wherein a periphery of the brake component is made of magnetic conductive material; a plurality of sets of electromagnets fixedly arranged at radial outward of the brake component; a sensor device for sensing a rotational speed and direction of the rotor shaft; and a controller connected to the sensor device, wherein the controller receives signals from the sensor device and supplies power to the plurality of sets of electromagnets based on the signals. The centrifugal compressor and refrigeration system according to the various embodiments effectively suppress the reverse rotation of the compressor rotor shaft caused by the reverse airflow during unexpected shutdown.

    摘要： An air pump having a rotatable chamber in simultaneous communication with a valve and a switch during inflation and deflation of an inflatable device. The air pump housing has a rotatable knob connected to a rotatable chamber. The rotatable chamber has a ramp bisecting the rotatable chamber into a primary compartment and a secondary compartment. During inflation, the rotatable chamber is in communication with a valve and the port of the secondary compartment diverts the airflow from an opening of the rotatable knob in a direction into the inflatable device when the rotatable chamber is rotated to a primary position. During deflation, the rotatable chamber is in communication with a valve and a port of the primary compartment diverts the airflow out of the inflatable device, whereby, the airflow is exhausted through an opening of the rotatable knob when the rotatable chamber is rotated to a secondary position.

    摘要： A method and system for the inflation of a sealed air product with accommodations for both a high capacity, low pressure blower and a low capacity, high pressure pump. The blower is attached to a fill tube and inflates the product until it approaches a point at which the pump does not have sufficient pressure to continue. The fill tube is coiled to prevent the air inside the sealed-air product from escaping and placed into a compartment behind a closable opening which is then closed. The air pump is then attached to an inflation port located on the sealed-air product which, when activated, inflates the sealed-air product to the desired air pressure. A pressure relief valves ensures the product is not over-inflated. After use, air may be allowed to escape through the fill tube, thereby allowing rapid deflation of the product.
