Vacuum oven is widely used in medicine, food, light industry, chemical industry and other industries for low-temperature drying.
Vacuum oven has the advantages of fast drying speed, small pollution and no damage caused by the inherent quality of dry goods. There are always various problems more or less in using vacuum oven, making the operator upset and distracted. The following will briefly list the solutions to solve common failures of vacuum oven based on years of experience and research of the vacuum oven supplier.
The reason why there is no way to dry may be caused by the wrong usage. Vacuum drying is done in a closed environment, so if the dried water vapor is not discharged in time, it will cause the water vapor to enter the material again, resulting the failure to dry.
Replenishing the air at regular intervals and using a vacuum pump to pump the water vapor out the chamber so that it doesn't always fail to dry.
The reason for vacuum absorption is the misoperation in closing the vacuum oven with pump. It should be closing the valve first and then the vacuum pump. If the order is reversed, the water or oil in the vacuum pump will be sucked back affected by vacuum negative pressure. The green man may make this mistake.
Learn from experience and correct operation. If it is easy to make a mistake, it's necessary to add a check valve between the vacuum pump and vacuum oven. When the vacuum pump shuts down, the check valve will immediately close the valve and there will be no vacuum absorption.
Air leakage occurs when using for a long time. The most likely possibility is not that the industrial drying oven is broken but that the sealing element is damaged and aged.
Just replace the seal, and if that still doesn't fix the problem, the valve may be broken and you just need replace some valves.
Open and close the door frequently or the temperature sensor is damaged.
First as far as possible to reduce the frequency of opening and closing the door or replace the temperature sensor.
These are all the common failures and solutions of vacuum ovens mentioned in the article.
