introduction：The compressor is in operation，Some glitches are bound to occur，Even accident。A fault refers to an abnormal situation that occurs during the operation of the compressor，The compressor can be restored to normal operation once it is removed，An accident is an indication of damage。The two are often related，If the failure is not removed in time, it will cause a major accident。 Compressors are used to increase gas pressure and transport gas machinery。From an energy point of view，Compressor is a machine that converts the power energy of the prime mover into the pressure energy of the gas。With the development of science and technology，Pressure energy is used more and more widely，Makes compressors in many sectors of national economic construction

introduction： High-speed grinding can achieve the pursuit of modern manufacturing technology to improve product quality and labor efficiency。Practice proves：If the grinding speed is determined by35m/sIncrease to50～60m/swhen，General production efficiency can be improved30％～60％，The durability of the grinding wheel is improved0.7～1times，The parameter value of workpiece surface roughness decreases50％around。 General grinding speed up to45m/sThis is called high-speed grinding。I developed it in the 1980sZYS—811Fully automatic bearing[bearing:bearing（“Bearing”，Japanese person“shaft

introduction：Sand drying furnace The sand or core used for casting is heated﹐Vaporize the water it contains﹑An industrial furnace that evaporates for drying purposes。Organic matter in sand or core﹐Such as wood chips﹐It also burns away during the heating process﹐Thus, the permeability of sand mold is increased。Some bonding agents in the core﹐Such as oil and asphalt﹐After heating to have bonding ability﹐Thus, the strength of the core is increased。 The drying temperature depends on the material composition of the sand mold or core﹐The drying temperature of sand mold is400～500℃﹐The drying temperature of core is200～350℃。This kind of stove is mostly flame furnace﹐A good airflow is required in the furnace

introduction：In practical application，It is often encountered that the use of anti-rust grease can not achieve the desired anti-rust effect，It can even accelerate the corrosion of metal。The reasons can be examined from the following aspects。 1)Varieties of rust-proof oils There are many kinds of anti-rust grease，The characteristics of various oils are also different。Some have better displacement，Some have better resistance to moisture and heat，Some have better resistance to salt spray，Some high temperature resistance and good gas resistance，Each has its own specialty。Different types of oil，Different uses，There are short-term rust prevention between processes、Anti-rust lubrication and long-term storage anti-rust。The additives used in oil products are adapted to different metals，
