Embodiment Construction

[0026] see in conjunction Figure 1 to Figure 8 As shown, according to an embodiment of the present invention, a pump body assembly is provided, including a first flange 31, a second flange 34, a first cylinder 32, a crankshaft 33, and a sliding vane (not shown in the figure), the The first cylinder 32 has a hollow structure, the first flange 31 and the second flange 34 are located at both ends of the first cylinder 32 in the axial direction, and the crankshaft 33 passes through the first flange 31 and the second flange 34, and the crankshaft 33 has an eccentric portion, the eccentric portion is covered with a first roller 35, and the sliding plate is slidably connected to the chute of the first cylinder 32 Among them, the end of the sliding piece is connected to the outer peripheral wall of the first roller 35 by friction, so that the hollow structure is divided into an air suction chamber (low pressure chamber) and an exhaust chamber 1 (high pressure chamber). The exhaust c...

Abstract

The invention provides a pump body assembly, a rotary compressor and an air conditioner. The pump body assembly comprises an air exhaust chamber; the air exhaust chamber is provided with a first air exhaust port; a silencer is arranged at the downstream of the first air exhaust port; the silencer is used for buffering and reducing noise of airflow exhausted by the first air exhaust port; a secondair exhaust port is formed in the silencer; the through-flow area of the first air exhaust port is S1; the through-flow area of the second exhaust port is S0; and S0 and S1 satisfy an relational expression that 0.314<S0 / S1<0.865. According to the pump body assembly, the rotary compressor and the air conditioner, the oil spitting rate of the compressor can be reduced, so that the reliability risk of the compressor caused by insufficient lubrication due to a too high oil spitting rate is reduced; and the refrigerating capacity of the compressor is improved, and high efficiency of the compressoris achieved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a pump body assembly, a rotary compressor and an air conditioner. Background technique [0002] The rolling rotor compressor, that is, the rotary compressor pump body assembly is composed of a cylinder, a roller, a crankshaft, an upper and lower flange assembly (including an upper and lower flange, an exhaust valve plate and a valve plate limit baffle) and a sliding plate. The parts of the pump body cooperate with each other to form a closed high-pressure chamber (exhaust chamber or compression chamber) and a low-pressure chamber (suction chamber). The volume of the low-pressure chamber changes periodically. When the volume of the compression chamber decreases to a certain extent and the gas pressure in the compression chamber reaches or exceeds the back pressure of the valve plate above the flange exhaust port, the valve plate opens and the gas in the compre...
