ZJ系列罗茨真空泵维护保养
ZJ系列罗茨真空泵维护保养:一、定期检查:1、每日检查:a)油位检查:油量过多,使温度升高,油量过少,造成润滑不良。b)温度检查:用温度计检查泵各部位温度。c)电动机负荷检查:用功率表或电流,电压表测量电动机负荷。2、每月检查:联轴器及垫片是否损坏和松动。3、每3个月检查:
Stainless steel application range
Heat resistanceIn intermittent use below 1600 degrees and continuous use below 1700 degrees, 316 stainless steel has good oxidation resistance. In the range of 800-1575 degrees, it is best not to continuously act on 316 stainless steel, but when 316 stainless steel is continuously used outside this
Corrosion resistance of stainless steel
304 is a versatile stainless steel, which is widely used to make equipment and parts that require good overall performance (corrosion resistance and formability).301 stainless steel shows obvious work hardening during deformation, and is used in various occasions requiring higher strength.302s
Types of stainless steel materials
In layman's terms, stainless steel is steel that is not easy to rust. In fact, some stainless steels have both rust resistance and acid resistance (corrosion resistance). The rust resistance and corrosion resistance of stainless steel are due to the formation of a chromium-rich oxide film (passi

What are the stainless steel materials
Stainless steel material is a kind of material with brightness close to mirror surface, tough and cold touch. It is a relatively avant-garde decorative material with excellent corrosion resistance, formability, compatibility and toughness. It is used in heavy industry and light industry. , Daily nec
Card sleeve ball valve applications and characteristics
Card sleeve ball valves are mainly used for long-distance pipeline transportation of oil and natural gas and city gas pipeline systems. Due to its unique characteristics, the long-distance pipeline valve fully considers its ability to withstand pipeline stress, safety, weather resistance and long-te
高温轴承的温度等级
高温轴承的温度等级如下:1、0~600高温轴承:一般温度等级分为200、300、400、500、600,常用温度等级为300和500两个等级。2、600~800高温轴承:此种高温轴承一般分为两种,全高温钢制耐高温轴承和陶瓷混合高温轴承。3、800--1200高温轴承:此类轴承一般以氮化硅陶瓷为原料,替代钢材难以达到的高温环境。https://en.kataoq
Tool mounting and tool matching for common thread tools
Loading and matching of ordinary thread tools:If the turning tool is installed too high or too low and too high, when the knife reaches a certain depth, the back surface of the turning tool will stand against the workpiece, increase the friction force, and even bend the workpiece top, resulting in t
Programming machining of common thread
Programming processing of ordinary thread:In the current CNC lathe, thread cutting generally has three machining methods: G32 direct cutting method, G92 direct cutting method and G76 oblique cutting method, because of the different cutting methods, programming methods are different, resulting in dif
