The first thing we should look at is their ability to handle clothes. There are two methods: one is to directly see whether the treated clothes meet our standards, and the other is to compare them according to the test values before and after washing. The higher the value, the better.
2. Wear rate: one cycle, judged by collecting the number of fallen fluff and visually inspecting the surface quality of clothes; The test method of fabric strength is to sew the standard sample on the measuring piece, continuously wash the foam plastic block, coat the nylon stocking, and gently press it on the inner surface of the cage to wipe it. Don't hang or hook the stockings, and the wear rate of the second-hand dry cleaning machine is qualified.
Third, the impact of work: If the second-hand washing equipment has a relatively loud noise that affects people's normal life, there is no doubt that it must be inferior.
4. Distillation boxes of second-hand dry cleaning machines are divided into three types: electric heating type, steam heating type and new full steam heating type, and the latter has been widely used by manufacturers all over the world. The distillation rate of the distillation box depends on the washing capacity and structure of the second-hand dry cleaning machine, and the distillation rate refers to the amount of solvent that can be distilled and regenerated per kilogram of washing capacity per hour. The distillation rate is not as high as possible, but appropriate, so as to ensure the amount of solvent needed for washing by second-hand dry cleaning machines. Refers to the energy consumed by the second-hand dry cleaning machine to wash each kilogram of clothes, including water, electricity, steam, etc. , all converted into standard consumption. The smaller the energy consumption, the higher the efficiency of the second-hand dry cleaning machine.
5. Working ability: If the capacity of the second-hand washing equipment is similar to that of the new machine, or can be compared with the normal machine, then we can buy and use it with confidence.
In addition, we should pay attention to check the wiring problem of the second-hand bathroom equipment to see if it is damaged or aging. This is a detail problem, but it is the most important one. Everyone must be vigilant.
I am an expert in this field, hehe, you can continue to ask any questions, but remember to give me a good evaluation! ! !
