Brief introduction of the burner fuel delivery system-gas and oil valve train and pumping station
There are several different ways for fuel delivery systems, including valve train for fuel gas/oil/liquid and pumping stations for fuel oil/liquid. The liquid/oil valve train or pump station produced by us mainly includes: oil pump, return valve, oil filter, oil pressure gauge, oil pipe and joint, fuel oil solenoid valve, nozzle, safety valve, back-pressure valve flow control system, monitoring system, heavy oil preheater etc. The gas valve train usually includes: gas solenoid valve, gas filter, leak detector, pressure switch, gas regulator valve, gas pressure gauge, gas reducing valve, etc. Customers can appoint us to select these important parts, and can also appoint some international brands components like SUNTEC, DANFOSS, RIELLO, NOP etc.
The layout condition of the oil pump pipeline refers to the height, distance and trend of liquid delivery, as to calculate the system pressure and check the power. If necessary by pipe system data, should also draw device characteristics curve. When design and arrange pipelines, pay attention to the following matters:
Large pipe diameter: low liquid flow speed and low resistance loss, but cost is high; small pipe diameter: resistance loss and pump pressure will be greatly increased, which will increase the equipped power, cost and operating fee. Therefore, it should be considered comprehensively for both technology and economy.
The discharge side of the pump must be equipped with valves and non-return valves. The valve is used to adjust the working conditions, and the non-return valve can prevent the oil pump from reversing when the liquid flows back.
Try to use straight pipe, reduce accessories and shorten pipe length. When elbow is necessary, the bending radius of the elbow should be 3-5 times the diameter of the pipe, the angle is better to greater than 90 ℃.
The discharge pipe and its joints shall consider the maximum pressure they can withstand.
