What is the principle of acid and alkali resistant chemical pump?

　　Acid and alkali chemical pump is according to international standards and combined with non-metallic pump process design and manufacture of pumps, because the pump has a corrosion-resistant, abrasion-resistant, heat-resistant and other advantages, so it is often used in the chemical industry, wastewater, plating and other industries, it is a very common kind of pump. The Schwab Pump & Valve to explain is the working principle and characteristics of acid and alkali chemical pumps, so that we can have a clear understanding of the pump, the following please follow the editor to take a look at it.

　　The working principle of acid and alkali resistant chemical pump:

　　Before the acid and alkali resistant chemical pump starts, the pump casing is filled with the conveyed liquid; after starting, the impeller is driven by the shaft to rotate at high speed, and the liquid between the vanes must rotate with it. Liquid under the action of centrifugal force, thrown from the center of the impeller to the outer edge of the energy, high speed away from the outer edge of the impeller, into the worm shell pump casing.

　　Before working, the pump body and feed pipe of acid and alkali resistant chemical pump must be filled with liquid and in a vacuum state. When the impeller rotates rapidly, the vane prompts the liquid to rotate rapidly, and the rotating liquid material flies away from the impeller under the action of centrifugal force. After the water in the pump is thrown out, a vacuum zone is formed in the middle of the impeller. The liquid material is pressed into the feeding pipe through the pipe network under the action of atmospheric pressure. This enables continuous transportation.

　　Inside the worm casing, the liquid decelerates due to the gradual expansion of the flow path, then part of the kinetic energy is converted into hydrostatic energy, and finally flows into the discharge pipe at a higher pressure to be sent to the place where it is needed. When the liquid flows from the center of the impeller to the outer edge, a certain vacuum is formed in the center of the impeller. Because the pressure above the tank level is greater than the pump inlet pressure, the liquid is continuously pressed into the impeller. It can be seen that as long as the impeller keeps rotating, the liquid will be continuously sucked in and discharged.

　　Features of acid and alkali resistant chemical pump:

　　1, backwashing into the pool (well) when flushing high speed and jet flow, churning efficacy is very obvious and effective.

　　2、Only in the need for into the pool (well) flushing when using the pump's water energy, do not need to rinse stirring, the flushing valve automatically closes, not a waste of pump power, energy and water conservation.

　　3, the use of static head of water into the pool is not subject to the size of the limitations, even if the static head of water into the pool on the valve is zero, as long as the pump pressure water flow, the flushing valve will be able to work normally.

　　4, flushing time can be pre-set, generally set at 20 seconds to 50 seconds is appropriate, the flushing valve flushing time can be adjusted to set a longer or shorter.

　　5, can be matched with more different head of the pump, the working head in the range of 3-50 meters flushing valve can work well and normally.

　　6, the opening and closing function of the flushing valve by the valve itself and the pump water can be jointly realized, without additional configuration of cables and electrical components, etc., both simple and safe and reliable.

　　7, equipped with a variety of models of flushing valve, and can be adjusted to achieve a variety of jet direction to meet the needs of different working conditions and different performance of the sewage pump.

　　8、Novel structure, easy to use, durable and reliable.
