What Are The Misunderstandings in Using Fluorine-lined Pipeline Pumps?

Fluorine-lined Pipeline Pumps are suitable for long-term transportation of acids, alkalis, oxidants and other corrosive liquids of any concentration under the temperature conditions of -85℃~+200℃. GF is used in petroleum, chemical industry, metallurgy, electric power, papermaking, flue gas desulfurization, dust removal, food pharmaceuticals and synthetic fibers and other sectors.

The fluorine-lined pipeline pump adopts the excellent hydraulic model and the performance parameters of the IS type centrifugal pump, and is cleverly designed on the basis of general vertical pumps. It has extremely strong corrosion resistance and can replace precious metals such as 316L stainless steel and titanium alloy. It also has the advantages of high energy saving, low noise and reliable performance.

Misunderstandings in the use of fluorine-lined pipeline pumps are as follows:

1. High-lift pumps use low-lift pumps to pump water. Some customers who use village cyanide pipeline pumps feel that the lower the pumping head, the smaller the motor load. Due to this misunderstanding, when purchasing a cyanide-lined pipeline pump, most people will choose a higher pump head. In fact, the first glance determines the type of pump, and the power consumption is proportional to the actual flow rate of the pump. Since the flow rate of the pump decreases with the head, the higher the head, the smaller the flow rate and the smaller the power consumption: On the contrary, the greater the flow rate, the greater the power consumption. Therefore, in order to prevent motor overload, it is generally required that the actual pumping head of the pump is not less than 60% of the calibrated head.

2. When installing the water supply pipeline, the horizontal section will be horizontal or warped upward. In this way, air gathers in the water supply pipe, the vacuum degree of the water pipe and village oxygen pipe pump is reduced, and the water suction head of the pump is reduced, which will lead to a reduction in water output. The correct way is to tilt the horizontal section slightly towards the direction of the water source. It cannot be horizontal, let alone upward. warping.

3. The water inlet of the liner pump is directly connected to the elbow. This will cause uneven distribution of water flow into the impeller through the elbow. When the diameter of the water supply pipe is larger than the pump inlet, please install an eccentric throttle. The flat parts of the eccentric tube should be installed on the upper surface, and the inclined parts should be installed on the lower surface. Otherwise, collect air, reduce water or pump, and make a pounding sound.

4. The water level at the outlet of the outlet is higher than the normal water level of the outlet pool. In this case, the pump flow rate will be reduced. When the outlet must be higher than the outlet level under terrain conditions, the outlet should be installed with a time pipe and a short pipe. The water pipe is in the form of a siphon to reduce the water outlet height.

5. When installing the bottom valve, the end of the water supply pipe is not vertical. After installation, the valve cannot close by itself, which will cause water leakage. The correct installation method is that the end should be vertical. When the water pipe cannot be installed vertically under terrain conditions, the water pipe The angle between the axis and the horizontal plane must be more than 60%.
