| 真空泵的泵体的布置结构决定了泵的总体结构。 The overall structure of the vacuum pump is determined by the arrangement of the pump body. 立式结构的进、排气口水平设置，装配和连接管路都比较方便。但泵的重心较高，在高速运转时稳定性差，故这种型式多用于小泵。 The vertical structure has horizontal inlet and outlet, and it is convenient to assemble and connect pipelines. But the center of gravity of the pump is high, and its stability is poor at high speed, so this type of pump is mostly used for small pump. 卧式泵的进气口在上，排气口在下。有时为了真空系统管道安装连接方便，可将排气口从水平方向接出，即进、排气方向是相互垂直的。此时，排气口可以从左或右两个方向开口，除接排气管道一端外，另一端堵死或接旁通阀。这种泵结构重心低，高速运转时稳定性好。一般大、中型泵多采用此种结构。 The air inlet of the horizontal pump is on the top and the air outlet is on the bottom. Sometimes, in order to facilitate the installation and connection of vacuum system pipes, the exhaust port can be connected from the horizontal direction, that is, the inlet and exhaust directions are mutually perpendicular. At this time, the exhaust port can be opened from the left or right direction. In addition to connecting one end of the exhaust pipe, the other end is blocked or connected with the bypass valve. The pump has low center of gravity and good stability at high speed. Generally, large and medium-sized pumps use this structure. 泵的两个转子轴与水平面垂直安装。这种结构装配间隙容易控制，转子装配方便，泵占地面积小。但泵重心较高且齿轮拆装不便，润滑机构也相对复杂。 The two rotor shafts of the pump are installed vertically with the horizontal plane. The assembly clearance of the structure is easy to control, the rotor is easy to assemble and the pump occupies a small area. However, the center of gravity of the pump is high and the gear is inconvenient to be disassembled, and the lubricating mechanism is relatively complex. |
