Disclosed is a pump assembly, a piece of fluid machinery comprising the pump assembly, and a heat exchange apparatus comprising the fluid machinery, the pump assembly comprising: a cylinder (10) having an inner cavity (11) and a sliding vane slot (12) in communication with the inner cavity (11); a piston (20), the piston (20) being rotatably arranged inside the inner cavity (11); a sliding vane (30) slidably arranged in the sliding vane slot (12) , wherein the head of the sliding vane (30) being in contact with an outer peripheral face of the piston (20); and a sliding vane spring (40) arranged at the tail of the sliding vane (30), the sliding vane spring (40) having a compressed state when compressed by the sliding vane (30) and a free state when separated from the sliding vane (30). The acting force between the head of the sliding vane (30) and the piston (20) is reduced, thus reducing the energy consumption during the operation of the pump assembly.

A multi-tank dual-stage enthalpy increasing compressor comprises a lower cover plate (10), a lower flange (9), an upper division plate (4), a middle division plate (5), and at least one middle cavity volume formed between each pair of the lower cover plate (10) and the lower flange (9), and the upper division plate (4) and the middle division plate (5). A total middle cavity volume is a sum of all middle cavity volumes. A ratio of a product of a volume ratio and the total middle cavity volume or one volume of the total middle cavity volume to the square of a secondary tank output volume is within a specified range. An air withdrawal volume ratio is a ratio of a secondary stage air withdrawal volume to a primary stage air withdrawal volume. The compressor provides stable air withdrawal at a secondary tank and smooth air release at a primary tank in a dual-tank or triple tank arrangement by configuring reasonable middle cavity volumes, effectively improving a problem in which a pressure fluctuation ...

Disclosed is a sliding vane control structure for a variable-capacity air cylinder, comprising a pin (113, 213) arranged under a sliding vane (11), and the pin (113, 213) has a first position capable of stopping the sliding vane (11) and a second position capable of being separated from the sliding vane (11); a low-pressure passage (115, 215) is arranged under the pin (113, 213); a surface seal structure is arranged between the pin (113, 213) and the low-pressure passage (115, 215), and when the pin (113, 213) is at the second position, a surface seal is formed at the lower end of the pin (113, 213). Since the sliding vane control structure is provided with a surface seal structure, the sealing effect of the surface seal is far better than that of a clearance seal, greatly reducing the leakage of refrigerant, consequently, the efficiency of a compressor is increased when a variable-capacity air cylinder is in a working mode, and the performance of the compressor is optimized. Also disclosed ...
