Modern chemical industry to requirements of molten salt pump

    Modern chemical fluorine plastic self-priming pump requirements for equipment is more and more demanding. It is not only the performance requirements to meet the process requirements, but also has the advantages of environmental protection, energy saving and other features. The equipment of the traditional heavy oil is clearly to say "no".

    Here sees the specific requirements:
    ①Under certain operating conditions (such as temperature, pressure, etc.) with sufficient mechanical strength.
    ②The safety and reliability of continuous operation.
    ③It has excellent resisting corrosion.
    ④The sealing is good.
    ⑤The high efficiency and low energy consumption.
    Pressure vessels is the equipment that it has specific feature and it can bear the pressure in industrial production. It is said [1] pressure fluorine plastic self-priming pump container. Storage vessel, reaction’s vessel, the calorimeter and a separate container belong to the pressure vessel.
    In order to distinguish with the general container (atmospheric pressure vessel), the container is known as the pressure vessel which is the same as the three conditions: (1) the maximum working pressure (Pw) (Note 1) is greater than or equal to 0.1Mpa (excluding the liquid static pressure, the below is same);
    Internal diameter (non - section refers to its maximum size) is greater than or equal to 0.15m, and the volume (V) (Note 2) is greater than or equal to 0.25m³; (3) containing medium for gas liquefied gas or the maximum operating temperature is higher than the standard boiling point liquid.
    The use of pressure vessel is very extensive. It plays an important role in the petrochemical industry, energy industry, scientific research and military departments of the national economy. Pressure vessel is easy to prone to explosion, fire and endanger personnel, equipment and property safety and environmental pollution the pressure vessel accident due to the sealing, pressure medium and other reasons. Pressure vessel is generally consist of six constitute the majority of the container body. They are the cylinder, head, flange, seal, hole and pipe, support.       In addition, it is equipped with safety devices, meter and inside parts of completing different role in a production process. At present, all the countries in the world list it as important products supervision and inspection. It is by the specialized agencies to designate. You should be in accordance with the provisions of national regulations and standards to implement supervision and inspection technology of fluorine plastic self-priming pump.
