My family has a sewing machine. when sewing insoles, there is always a problem of cutting the needle on the line. ask the master how to solve it? Thank you! 10 Teach you a simple way,Hot the noodle with boiling water,With the addition of point oil (that is, silicone oil), it is not easy to break the clip yellow,Change a needle,No. 16 needle.You try again.Are you a woman,

How does the computer sewing machine adjust the amount of oil? is it bigger or smaller? First of all, let's check whether the needle is installed correctly,It's better to change a new machine needle.2, if still not,We went on to open the needle,Turn the needle to the lowest position,Look at the rotary shuttle tip from the machine needle 8mm or so.If yes,Then raise the machine needle 2.3mm or so,Look at whether the rotary shuttle tip coincides with the machine needle center.At this time, the needle and the tip of the shuttle can not be too tight,There should be 0.1 gap.3, sometimes the needle has a little bend will also jump the needle, the easiest way is to change the needle to try, if not, when the needle is installed, try a little bit, only a little bit, otherwise, it will break the line. sometimes such a simple operation is also very effective.4. it also has something to do with the thickness of your sewing.Thick things should be thicker,If the needle is fine, it will jump,If something thin,If

What is mechanical filtration and what equipment is there? Such as sand cylinder, multi-media filtration, activated carbon filtration, etc,The filter medium is hard particles,Uniform distribution of filter materials along the direction of filter flow,Therefore, the specific surface area is small, the amount of sewage interception is small, the filtration speed is slow, and the filtration accuracy is low,,The filtration rate is generally 10 m/h.Below m2,The advantage is that it is easy to reverse wash and regenerate;Elastic fiber filter material,Including fiber ball filter material and fiber bundle filter material,Fast filtration speed, high filtration accuracy,However, the amount of interception is limited,Backwashing is not possible,Not easy to regenerate,Built-in air bag for filter equipment,Difficult management,The filter speed is generally 20-50 m/h.M2,;Now the traditional process will be replaced sooner or later,Fiber filters are now more and more used by enterprises.For example: the AFF (asymmet
