Selection of desulfurization pump in ammonia desulfurization project
With the continuous economic development, more and more sulfur dioxide is emitted from fossil fuels, causing serious environmental problems and causing huge economic losses. Control of sulfur dioxide emissions has become the primary content of the current environmental issues, flue gas desulfurization technology has been greatly developed. 1 In flue gas desulfurization process, ammonia desulfurization is an efficient, low-energy wet desulfurization. Desulfurization system desulfurization raw...
Corrosion-resistant magnetic pump assembly and maintenance
Corrosion-resistant magnetic pump as the name suggests is a corrosion-resistant pump, mainly for the transport of corrosive liquids. Corrosion-resistant magnetic pump is a more common in recent years, a magnetic pump, which uses the world's best corrosion-resistant materials. But the instrument will be faulty, so we usually pay attention to maintenance, the following to share with you about the corrosion-resistant magnetic pump assembly and maintenance. (A) assembly sequence 1, the heating...
The working principle of pumps and their use classification
1 - the definition of water pump Usually to enhance the liquid, liquid transport or increase the pressure on the liquid, that is, the mechanical energy of the prime mover into liquid energy to achieve the purpose of pumping liquid machine collectively referred to as the pump. 2-pump working principle 1, positive displacement pump: the use of the working chamber volume change of periodic delivery of liquid. 2, vane pump: the use of leaves and liquid interactions to transport liquid. 3-pump...
Flow measurement instrument several test methods difference
First, the selection of several test methods Flow measurement instrument verification, usually using real-flow test and dry test in two ways. Which way to check the flow meter depends on the measurement system requirements of measurement uncertainty, was seized flow meter type, use, with the test conditions, the cost of testing and many other factors. Generally, the flow meters used for liquid metering (such as crude oil and water meters) basically use the real flow test, while the gas flow...
Electric pump features advantages and disadvantages do you understand
Electric pump is to provide hydraulic fluid pressure of a hydraulic components, is a pump. Its function is to convert the mechanical energy of power machines (such as electric motors and internal combustion engines) into liquid pressure energy. The output flow can be adjusted according to the needs called variable pump, the flow can not be adjusted called quantitative pump. Hydraulic system commonly used pump gear pump, vane pump and plunger pump 3 kinds. Gear pump: smaller, simple structure,...
Anti-corrosion valve solenoid valve procurement to consider the necessary technical factors at a glance
Solenoid valve procurement only clear the specifications, types, pressure to meet the procurement requirements of the practice in the current market economy environment is imperfect. Because the valve manufacturer in order to compete for the product, each in the valve under the concept of a unified design, different innovations, formed their own corporate standards and product personality. Therefore, when the valve procurement more detailed technical requirements, and manufacturers to obtain...
