Hey there! As a supplier of vacuum oil filter units, I've had the pleasure of getting up close and personal with these nifty machines. So, I thought I'd share the lowdown on the main components of a vacuum oil filter unit.
1. Inlet Pump
Let's start with the inlet pump. This little guy is like the doorman of the vacuum oil filter unit. Its job is to suck the dirty oil from the storage tank or the equipment that it's being used in and into the filter unit. It needs to be powerful enough to handle the flow rate of the oil, which can vary depending on the size of the unit and the application.
There are different types of inlet pumps, such as centrifugal pumps and gear pumps. Centrifugal pumps are great for high - flow applications because they can move a large volume of oil quickly. Gear pumps, on the other hand, are more precise and are better for applications where a consistent flow rate is crucial.
2. Pre - filter
Once the oil is inside the unit, it first hits the pre - filter. This is like the first line of defense. The pre - filter is designed to remove the larger particles from the oil. These can include things like rust, dirt, and debris that have found their way into the oil over time.
The pre - filter usually consists of a filter element, which can be made of different materials like cellulose, glass fiber, or synthetic materials. The choice of material depends on the size of the particles you want to remove and the type of oil being filtered. A good pre - filter can significantly extend the life of the other filters in the unit by preventing large particles from clogging them up.
3. Heating System
After passing through the pre - filter, the oil moves on to the heating system. Heating the oil is an important step because it reduces the viscosity of the oil. When the oil is less viscous, it's easier for the water and gas to separate from it.
The heating system typically uses electric heaters or steam heaters. Electric heaters are easy to control and are often used in smaller units. Steam heaters, on the other hand, are more efficient for larger units and can heat the oil to a more consistent temperature.
4. Vacuum Chamber
The vacuum chamber is the heart of the vacuum oil filter unit. It's where the real magic happens. Inside the vacuum chamber, the pressure is significantly reduced. When the pressure drops, the boiling point of water and other gases in the oil also drops. This causes the water and gases to evaporate and separate from the oil.
To make this process even more effective, the oil is often sprayed or dispersed inside the vacuum chamber to increase its surface area. This allows for more water and gas to be removed in a shorter period of time. The evaporated water and gases are then removed from the vacuum chamber by a vacuum pump.
5. Vacuum Pump
The vacuum pump is responsible for creating and maintaining the low - pressure environment inside the vacuum chamber. It sucks out the evaporated water and gases, keeping the pressure low so that the separation process can continue.
There are different types of vacuum pumps, such as rotary vane pumps and piston pumps. Rotary vane pumps are commonly used because they are reliable and can achieve a relatively high vacuum level. Piston pumps are more suitable for applications where a very high vacuum level is required.
6. Fine Filter
After the oil leaves the vacuum chamber, it goes through the fine filter. This filter is designed to remove the smaller particles that the pre - filter may have missed. These can include things like wear particles and contaminants that are only a few microns in size.
The fine filter uses a very fine filter element, often made of a high - performance material. It helps to ensure that the oil leaving the filter unit is clean and meets the required quality standards.
7. Outlet Pump
Finally, the clean oil is pumped out of the filter unit by the outlet pump. This pump is responsible for sending the filtered oil back to the storage tank or the equipment where it will be used.
The outlet pump needs to be able to handle the pressure and flow rate requirements of the system. It's usually a smaller pump compared to the inlet pump, but it still needs to be reliable to ensure a continuous supply of clean oil.
Now, let me introduce you to some of our amazing products. We have the ZY - 20 Dehydration/Degassing/Remove Impurities Vacuum Transformer Oil Cleaner. This unit is great for removing water, gas, and impurities from transformer oil, ensuring the optimal performance of your transformers.
Another great option is the ZY - 10 600 LPH Vacuum Transformer Oil Filtration Machine With PLC Controller. The PLC controller makes it easy to operate and monitor the filtration process, giving you more control over the quality of the filtered oil.
