使用说明：
Usage explanation:
l 安装时螺旋机各机壳及两端机架的纵向不直度和水平度允差为长度的1/1000。底座在机壳装妥以后使之着实，再拧紧地脚螺钉。
l 进出料口现场安装，法兰间连接加密封垫片，不得有间隙。
l 机体装妥后应检查各存油处是否有足够润滑油。
l 运行应平稳可靠，轴承箱不得发生漏油现象，轴承温升不得超过20℃。
l 运行时加料应均匀，否则易造成输送物料的积塞，驱动装置过载。被输送物料内不得混入坚硬的大块物料，避免螺旋卡死造成机体损坏。
l 必需保证输送机无负荷起动，在停车前应停止加料，待机壳内输送完物料后，方能停止运转。
l 使用中应经常检查各机件的工作状态，注意各传动件是否运行良好，应经常加润滑油。
l The error of portrait linearity and horizontal of body and bracket is the 1/1000 of length when install screw engine. Install the support on the body steadily and then lock down the ground bolt.
l Install the inlet and outlet on the spot. Add sealing shim between the two flanges and there is no clearance.
l Check the oil store if there is enough lubricant after the installation is over.
l The operation should be steady and reliable. There is no oil leakage in the bearing box and the raising temperature is not more than 20℃.
l Feed the material equally, otherwise the material will be jammed and the driving device is over loaded. There is no big block hard material in the transported material to avoid blocking and damaging.
l Make sure that the conveyer starts without load and stop feeding before stop the engine. Stop the conveyer after the material is transported completely.
l Often check the working condition of all parts during the operating. Pay attention to the working of transmission parts and add lubricant to the transmission parts.
