When you choose a vacuum Drying Oven, you will definitely do some research on its quality and performance, just like when we buy a car, we always have to check how to choose a good one on the forum. Let's analyze how to distinguish the good and bad of the Drying Oven.
The first thing to look for in a vacuum Drying Oven is the degree of vacuum. This degree of vacuum is the basic requirement, such as what kind of vacuum capacity it can achieve, and how long it can maintain the vacuum after vacuuming. The general vacuum degree requirements can reach the installed Take the pressure gauge of -0.1~0MPa as an example, if the vacuum state can reach the displayed -0.1MPa, then there will be no problem with the vacuum degree, and then we will look at this -0.1 How long MPa can be kept, according to your own needs, a good vacuum Drying Oven can guarantee that there will be no air leakage for several days or even dozens of days.
The degree of vacuum is one aspect. In addition to the degree of vacuum, you should also check whether the structural design of the vacuum Drying Oven is reasonable to ensure that the required temperature can be reached. The electric heating model should ensure that it has enough power output to ensure the temperature; Heating, steam heating, heat conduction oil heating type, we need to see if its drying rack design meets the heat dissipation requirements. If the pipeline of the drying rack is denser, it means that the heat dissipation area will be larger, and the heat dissipation will naturally be better. The uniformity of the heat sink can also be guaranteed. Generally, it is very useful to set the cooling pipes at a distance of 40~50mm; but if a coil-type drying rack is used, the density of the cooling pipes is generally between 100~120mm, and it is difficult to guarantee its uniformity. If the heat dissipation area is sufficient, it may happen that the set temperature cannot be reached all the time. Such a product is undoubtedly unsatisfactory.
In addition to the above 2 points, we have to look at the material and workmanship. Whether the material can meet the standard. For example, you want to buy a 304 product, but the result is a 201 product. There is a phenomenon of jerry building and inspection. Some unreputable companies do things. The root cause of preventing such phenomena is the price. The so-called first-class price and first-class goods. When we want to order a 304 drying box, we always feel that some merchants offer very favorable prices. There will be no tricks and you have to judge by yourself. Generally, manufacturers will not do this kind of thing, which is not conducive to long-term self-destruction. However, this kind of thing may still happen, so you must not choose those whose quotation is far lower than the normal quotation. It is not easy for companies to be cheated. When the material meets the requirements, it is naturally workmanship. Good workmanship also requires experience and equipment. Without good workers and well-equipped production equipment, it is impossible to make a good vacuum Drying Oven.
