Products made of stainless steel have gradually entered industrial applications because of their long service life, not easy to rust, and green environmental protection. Stainless steel pipeline pumps are among the best. The stainless steel pipeline pump included in the stainless steel pipeline pump has been widely used in the market in recent years, and is loved by the majority of users because of its corrosion resistance, long service life, light weight, safety and hygiene. Moreover, the cost of construction is comparable to that of ordinary sewage pumps, because the price of its brown metal has continued to increase over the years, and the price is almost the same. The used stainless steel material is a green and environmentally friendly material, which can be recycled 100%, so in recent years, it has become a leader in stainless steel high temperature and corrosion resistant submersible pumps. Especially in recent years, countries in the food industry have put forward higher requirements. Stainless steel materials have gradually entered the stage of history because of their safety and hygiene. For rigid requirements, stainless steel pump products represented by stainless steel submersible pumps have begun to shine in food products. With the sharp increase in the market, the stainless steel pipeline pump industry is facing new technological innovations. Various companies are also competing to launch their own killers, constantly improve their R&D teams, and study related core production technologies, so as to improve their competitiveness in the market. Pump products represented by stainless steel pipeline pumps are leading the entire pump industry to move forward, and the raw material market driven by this, new stainless steel materials continue to come out. Various patented technologies and the continuous improvement of specifications are constantly driving the entire industry chain to a higher and more orderly goal. At the same time, it is also expected that pump products led by stainless steel sewage pumps will go abroad and become more popular in the world. Play the pride of Made in China on the big stage.

At present, there are four flow control methods of centrifugal pump widely used in the market: outlet valve opening adjustment, bypass valve adjustment, impeller diameter adjustment and speed control. Common flow control methods of centrifugal pumps and their influence on energy consumption 1. Outlet valve opening adjustment The opening of the outlet valve is adjusted, and the pump is connected in series with the outlet pipeline regulating valve. Its actual effect is like using a new pump system. The maximum output head of the pump does not change, but the flow curve attenuates. Adjust the opening of the outlet valve, and the energy consumption is 94%. When the flow is low, the power consumption is large. 2. Bypass valve regulation In this method, the valve and pump are connected in parallel. Its actual effect is like using a new pump system. When the maximum output head of the pump changes, the characteristics of the flow curve also change, and the flow curve is closer to linearity. For bypass valve regulation, the bypass valve reduces the pump head to 55m, which can only be achieved by increasing the pump flow. As a result, energy consumption increased by 10%. 3. Adjust impeller diameter This method does not use any external components, and the flow characteristic curve changes with the diameter. After adjusting the impeller diameter and reducing the impeller diameter, the output flow and pressure of the pump are reduced, and the energy consumption is reduced to 67%. 4. Speed control The change of impeller speed directly changes the flow curve of the pump, and the characteristics of the curve remain unchanged. When the speed decreases, the curve becomes flat and the head and maximum flow rate decrease. Through speed control, the speed is reduced, the flow and head of the pump are reduced, and the energy consumption is reduced to 65%. 1) Total efficiency of pump system Both outlet valve regulation and bypass regulation methods will increase the pressure loss of the pipeline and greatly reduce the efficiency of the pump system. The adjustment of impeller diameter has little effect on the efficiency of the whole pump system. As long as the speed is not less than 50% of the normal speed, the speed regulation control mode basically does not affect the system efficiency. 2) Energy consumption level Assuming that the output flow of the pump is adjusted from 60m3 / h to 50m3 / h through the above four methods, the power consumption when the output is 60m3 / h is 100% (at this time, the pressure head is 70m) Vacuum Pump Heat Treatment Guide,Heat Treatment Equipment Liquid Ring Vacuum Pump
