150y-75型离心输油泵三维参数化设计（Three dimensional parametric design of 150y-75 centrifugal oil pump） (2) the operator shall be familiar with the working principle, structure and performance of the machine tools to be operated. Strictly prohibit the operation of undocumented persons. (3) inspect the machine tools for protection, insurance, signalling and mechanical transmission. Electrical parts should have reliable protective device, whether it is complete and effective. It is strictly forbidden to use machine tools with over specification, over load, over speed and over temperature. (4) the workpiece, fixture and tool must be clamped firmly. (5) check the positions of the handles before the machine starts. Lubricate the grease according to the lubrication gauge and observe the dynamic condition around it. When the machine starts, stand in a safe position to avoid the movement of the machine tool and the splash of iron filings. (6) after starting the machine, should speed 3 - 5 minutes, confirm the site isnormal, in the winter to operate a lathe must run temperature, check whether pipeline cracking, shall not transfer or take articles in the operation of the site. (7) adjust the machine speed, stroke, clamping workpiece and tools, as well as measuring workpiece, wiping machine tools, such as stability can only be carried out. (8) tools or other objects are not placed on the rail surface of the machine tool or on the worktable. (9) the iron filings shall not be directly removed by hand, and shall be cleaned with special tools. Such as a brush or hook. (10) where two or more than two people work on the same machine tool, 1 people must be designated as the commander of the aircraft and unified command shall be taken to prevent the accident.
