Many times, the staff will ignore the selection of screw air compressor, resulting in the unstable performance of screw air compressor. We should pay attention to the selection of installation location and make specific planning. The possible problems will be contained in the embryonic stage to ensure the useful and stable operation of screw air compressor.

螺杆空压机的安装地点应当选择在场地宽阔且采光较好的地方，这样能够方便机体的安装和未来维护保养及检修工作的实施开展。螺杆空压机的安装需要挑选相对干燥，空气流通较好，灰尘较少的地方，这样能够延长设备的使用寿命。如果工厂环境较差，灰尘比较多，应当适当加装前置的过滤设备来加以防护。在环境温度方面则不宜过高，一般要安装在低于40摄氏度的地方，过高的温度会建设设备运作时的空气输送量，从而在一定程度上使设备的效率降低。

The screw air compressor shall be installed in a place with wide site and good daylighting, so as to facilitate the installation of the machine body and the implementation of future maintenance and overhaul. The installation of screw air compressor needs to select places with relatively dry, good air circulation and less dust, which can prolong the service life of the equipment. If the factory environment is poor and there is a lot of dust, it should be properly equipped with pre filter equipment for protection. In terms of ambient temperature, it should not be too high. Generally, it should be installed at a place lower than 40 ℃. Too high temperature will reduce the air transmission capacity during the operation of the construction equipment, so as to reduce the efficiency of the equipment to a certain extent.

同时，在安装之前要预留出通路，如果条件允许，还可以设置天车，这样可以给未来的养护工作提供较大的便捷。一般来说，要在压缩机和墙面之间少留有70厘米以上距离作为预留出来的保养空间。而空压机离顶端空间距离也不能少于一米。

At the same time, access shall be reserved before installation. If conditions permit, crown block can also be set, which can provide greater convenience for future maintenance work. Generally speaking, a distance of at least 70cm shall be reserved between the compressor and the wall as the reserved maintenance space. The space distance between the air compressor and the top shall not be less than one meter.

此外，要预留安装风冷机组和水冷的位置，通过安装导风管把冷却的热风排除到室外。水冷机组的进出口都要安装阀门，假如冷却水存有杂物，需要提前安装好过滤器设备。

In addition, the position for installing air cooling unit and water cooling shall be reserved, and the cooled hot air shall be discharged outdoors through the installation of air duct. Valves shall be installed at the inlet and outlet of the water cooling unit. If there are sundries in the cooling water, the filter equipment shall be installed in advance.
