The dry vane vacuum pump is used extensively for industrial processes. This type of pump contains a coarse filter wire mesh, which prevents solid foreign dust from entering into the pump. When the pump is turned off, the valve meant for suction is closed and oil is prevented from going back into the system.
Some of The Reasons Why Many People Are Using This Type of Pump Are:
1. Durability
This type of pump is known for its durability. Because of its weight, these pumps have a very big shelf life. Also, this pump functions in the isothermal concept. Because of this, they can be used to pump flammable gas. Even though there is no friction surface and exhaust value, pumping gas along with water and gas mixture can be done properly. Although the efficiency is low; it is still widely used because of its impressive features.
2. Other Characteristics
Along with the primary features there are some other characteristics of the dry vane vacuum pump such as:
The extraction rate of the pump is 0.43-560 m3/min.
The temperature at which the pump runs is 10 ℃ and 40 ℃. This temperature can be achieved easily.
The minimum pressure (pabs )of the suction is 33-160 hpa.
The supporting power of this pump is 7.5-560 kW.
The material usually used to build this pump is either stainless steel or cast iron. This increases the overall durability of the pump.
If the pump pressure goes beyond 100 Pa, the scope of the pump is exceeded. Oil mist is produced, which in turn reduces the overall efficiency of the dry vane vacuum pump.
The Disadvantages of The Dry Vane Vacuum Pump:
As seen with the other machinery, there are some disadvantages that can be seen in this pump as well. Some of the disadvantages are:
The efficiency of the pump is very low; usually it is 30% and can go up to 50%.
The degree of vacuum is low because of its design and structure. However, more important is that the machine is restricted by the saturated vapor pressure of the working liquid.
It uses water as only the working fluid. The pumping fluid used is oil. Because of this, the pressure has to reach close to 130 Pa.
How to Fix Dry vane vacuum pumps?
Sometimes it is very easy to trouble shoot a dry vane vacuum pump. However, it is very important to classify the issue into a DIY and a major problem. If it is a major problem, then a professional should be hired as soon as possible. Some of the tips for trouble shooting:
If the motor of the dry vane vacuum pump makes a strong noise, it means that something is stuck in the motor. In such case, the motor should be checked to ensure its better functioning.
In order to increase the longevity of the pump, one has to source out the pump and all its parts from well-known suppliers. If this is not done, the lifespan is reduced drastically. The best suggestion here is to get in contact with those suppliers who are well-experienced in the market and also are known to import such materials.
Finally, it is important to understand the dry vane vacuum pump is required to maintain the correct pressure of the system. These pumps are very robust and help in maintaining a sustainable relationship with the machinery that is used to run businesses. It is widely used across many businesses, so it is important for those who are associated with this business to know its importance.
