Description

Technical Field

[0001] The utility model relates to the technical field of quality inspection barrels, in particular to an anti-vortex device for a quality inspection barrel. Background Art

[0002] Problems with the quality of aviation fuel can cause abnormalities in aircraft engines and affect flight safety, so the airport oil depot needs to inspect aviation fuel. At present, after the quality inspection barrel is filled with oil samples, when the oil pump is used to pump the oil products to the recovery tank, the suction force of the oil pump is too large, and the oil sample will generate a vortex in the quality inspection barrel, causing air to enter the oil pump, and the outlet pressure of the oil pump will instantly drop to the minimum, reducing work efficiency. Since the oil pump is a centrifugal pump, long-term air intake causes "cavitation" at the inlet of the oil pump. "Cavitation" refers to the sudden collapse of bubbles or vapor in the liquid due to pressure reduction or speed increase when there are bubbles or vapor in the liquid fluid, causing the performance of the pump to decline or even damage the pump.

[0003] For centrifugal pump impellers, "cavitation" will have the following effects on the pump:

[0004] a. Reduce pump efficiency: Cavitation hinders the flow of liquid, the flow path of the fluid in the impeller becomes longer, and the friction loss increases, thereby reducing the efficiency of the pump.

[0005] b. Increased noise and vibration: Cavitation causes liquid disintegration and impact, which will increase the noise and vibration of the pump, causing instability and vibration problems to the equipment.

[0006] c. Reduce flow and head: Due to the unstable liquid flow caused by cavitation, the flow and head of the pump will be affected, resulting in a decrease in pump performance.

[0007] d. Impeller wear: Liquid impact and collapse caused by cavitation may cause wear on the impeller surface, thereby affecting the operation and life of the impeller.

[0008] e. Reduced reliability and service life: Cavitation will accelerate the wear and corrosion of the pump, reduce the reliability and service life of the centrifugal pump, and may even cause pump failure and damage.

[0009] Therefore, based on the above problems, a quality inspection barrel anti-vortex device is proposed. Utility Model Content

[0031] During specific use, the circular tube 3 of the device is fitted and connected to the bottom of the quality inspection barrel. When discharging oil, the device uses the "siphon" principle to reduce the flow rate of the liquid by changing the flow direction of the liquid, so that the liquid first enters the gap between the conical tube 4 and the disc 1, and then enters the conical tube 4 and the cylinder 3 before being discharged, instead of being discharged directly. The multiple support sheets 2 can also block the vortex, thereby avoiding the generation of vortexes during the oil pumping process, thereby reducing the damage to the pump due to cavitation, and at the same time reducing the unstable liquid flow caused by cavitation, the flow rate and head of the pump will be affected, resulting in a decrease in pump performance, and other problems, thereby improving work efficiency.

The sealing installation ring 5 is made of rubber material. During installation, it is only necessary to insert the circular tube 3 into the oil drain port, and the sealing installation ring 5 fits tightly with the inner wall of the oil drain port, so that quick installation can be completed and assembly is convenient.

[0034] In order to increase the durability of the device, the disc 1, the conical tube 4, the circular tube 3 and the plurality of supporting sheets 2 are all made of stainless steel with good electrostatic conductivity, and the surfaces of the disc 1, the conical tube 4, the circular tube 3 and the plurality of supporting sheets 2 are coated with a nano-coating with strong anti-fouling performance.
