泵体组件、铸造模具和旋转式压缩机
摘要：
本发明提供一种泵体组件、铸造模具和旋转式压缩机。该泵体组件包括气缸(3)和设置在气缸(3)两端的第一轴承(1)和第二轴承(2)，气缸(3)和第一轴承(1)成型为一体；和/或，气缸(3)和第二轴承(2)成型为一体。根据本发明的泵体组件，能够有效防止气缸与轴承的相对位置发生改变，避免压缩机发生卡死现象。
摘要（英）：

The invention provides a pump body assembly, a casting die and a rotating compressor. The pump body assembly comprises an air cylinder (3), a first bearing (1) and a second bearing (2), wherein the first bearing (1) and the second bearing (2) are arranged at the two ends of the air cylinder (3). The air cylinder (3) and the first bearing (1) are integrally formed; and/or the air cylinder (3) and the second bearing (2) are integrally formed. According to the pump body assembly, changing of the relative positions of the air cylinder and the bearings can be effectively prevented, and the phenomenon that the compressor is stuck is avoided.
