First, there are many reasons for the vacuum pumping vacuum pumping, the main reasons are:
a. The time taken is too short.
?b. The vacuum pump is aged or not in place.
?c. Vacuum work is not good for sealing, there is air leakage when vacuuming.
?d. The vacuum pump power is too small to match the actual pumping speed ratio, and vacuum cannot be fully taken.
Second, the solution
1. Lengthen the vacuum time.
2. Replace the vacuum pump, pay attention to timely maintenance and replacement of the vacuum pump oil. If you have not done maintenance for a long time, please clean the vacuum pump and replace it. (Generally, the first maintenance is continuous work for 300 hours, after which you can work continuously for 500 hours for maintenance)
3. Check the vacuum chamber for air leakage. If there is air leakage, replace the sealing strip in time.
? 4. The vacuum pump is too small to achieve the desired vacuum effect, only the vacuum pump can be replaced. Generally the pumps range from 20-302.
Third, the maintenance and maintenance of mechanical equipment
After the mechanical equipment is bought and used again, it must be taken care of for a period of time. Just like the car, it should be regularly maintained. If the maintenance is not in place, no matter how good the equipment is, it will not be used for a long time.
Steroid hormones, also known as steroid hormones, are a class of tetracyclic aliphatic hydrocarbon compounds with a cyclopentane polyhydrophenanthrene nucleus. It has very important medical value. It has a clear role in maintaining life, regulating sexual function, body development, immune regulation, skin disease treatment and birth control.
Steroids include steroids (eg cholesterol, lanosterol, sitosterol, stigmasterol, ergosterol), bile acids and bile alcohols, steroid hormones (eg adrenal corticosteroids, androgens, estrogens),
