Selection of electric control valve for vortex air pump
source:Industry News release time:2021-07-29 Article author:Rosit Popular:Air band saw
Nowadays, more and more industries are used in vortex air pumps, especially some industries with high requirements for flow rate and opening height. Generally, certain electric control valves are selected. Electric control valves can be adjusted according to the needs of the working environment of each industry. And make relevant adjustments.
The main control parameters of the electric control valve are: nominal diameter, design nominal pressure, allowable temperature range of medium, flow coefficient, etc. However, the key to the quality of the electric control valve depends on the sealing performance of the electric control valve. However, the sealing performance of the valve is mainly divided into two aspects, one is internal leakage and external leakage, so you must pay attention to the sealing performance when choosing an electric control valve. When choosing an electric control valve, environmental protection, energy saving, easy installation and maintenance should also be considered, which can bring great convenience to the subsequent work.
In addition, if vibration occurs during the operation of the fan, it can be eliminated from the following aspects:
1. The pressure of the vortex air pump is high. a. The vortex air pump is selected incorrectly (the air volume is too small). b. The pipe is blocked. Disassemble the air outlet of the vortex pump, clean up the dirt in the pipe, and check whether the aeration head is blocked. If it is blocked, replace it. c. If the air chamber (oil and gas separation tank) is blocked, please disassemble the air outlet (open) of the vortex air pump and test the machine. If the pressure of the vortex air pump does not drop to 0MPA, there is a blockage fault in the air chamber, and the air chamber needs to be disassembled and checked. Check the pipeline.
2. The vortex air pump or motor bearing is damaged, disassemble the vortex air pump or replace the motor.
3. Damage to the inside of the vortex air pump, a. The inside of the vortex air pump may enter stolen goods.
4. The vortex air pump is rusty in the water, disassemble the machine for repair.
5. The vortex air pump room has a poor sound-absorbing design.
