Case Study of Tianjin Electroplating Factory
In September 2020, the head of Roots Blower Procurement Project of Tianjin Electroplating Factory said that the selection of Roots Blower puzzled him: how to select the specific type is a very important issue. If the selection is small, the aeration amount of the end slot is not enough, if the selection is large, the air amount is too large, and the surface of the plated parts is uneven. How can I choose just right?, How to select the type of Roots blower?
For this reason, we made a solution for him and finally purchased 10 Roots blowers. There are 6 three blade roots blowers and 4 standby blowers. The following is the purchase quantity of Tianjin Electroplating Plant
That is to say, as long as the air volume and pressure are calculated, it is not difficult to select Roots blower.
The wind pressure is the depth of the plating bath. Generally, the plating bath is one meter deep, and the corresponding pressure of Roots blower is 1000 mmaq, 2 meters is 2000 mmaq, and so on.
The calculation of air volume is more complicated. The air volume shall be calculated according to the number of cubic liquids in each tank and the total number of tanks. It also needs to be selected according to the process.
If you really don't know how to select Roots blower, you can contact Roots blower manufacturer for assistance. Knowing the wind pressure and air volume, the selection of roots blower is basically out.
Use of Roots blower for electroplating plant
Roots blower for electroplating plant It is a high pressure fan. Roots blower is a positive displacement fan. The air volume transported is proportional to the number of revolutions, and the gas is transported from the suction side to the discharge side. The principle of Roots blower in electroplating plant is somewhat similar Gear oil pump. The two rotors of the fan are similar to two "8" words. With this complex curve shape, the rotors continuously seal the pressure difference at the inlet and outlet, and the gas is sent to the high-pressure area between the rotor and the casing.
Secondly, roots blower installation for electroplating plant
As roots blower is a high-speed machine, it generates vibration and increases the vibration of roots blower due to the pulsation of internal air. Therefore, roots blower of electroplating plant needs to be fixed on the ground during installation. According to the type of fan
According to the size of the fan, a suitable square pit shall be dug at the corresponding position on the ground, and the anchor bolts shall be embedded. Then connect the fan with bolts and nuts in a square pit. Filled with cement concrete. After fixing the concrete, tighten the nuts. Fan base and coagulation
The soil is firmly connected together. This reduces the vibration displacement of roots blower during operation and improves the operation safety of equipment. And the service life of the fan is also greatly extended due to the reduced vibration.
Precautions for installation of Roots blower for electroplating plant
1. Roots blower shall not be installed in places where people often go in and out to prevent injury and scald.
2. Roots blower for electroplating plant shall not be installed in places where inflammable, explosive and corrosive gases are easily generated, so as to prevent accidents such as fire and poisoning.
3. According to the direction of air inlet and outlet and maintenance needs, there should be appropriate margin around the foundation surface.
4. When installing Roots blower in electroplating plant, check whether the foundation is firm, whether the surface is flat, and whether the foundation is higher than the ground.
5. When the roots blower for electroplating plant is configured outdoors, a rain proof shed shall be set.
6. The fan can be used for a long time under the ambient temperature of no more than 40 ℃. When the temperature exceeds 40 ℃, exhaust fan and other cooling measures should be installed to improve the service life of the fan.
