The company adheres to rigorous design and advanced manufacturing concepts, and innovates traditional technologies to meet the challenging working conditions in the chemical and industrial fields. Tailored customized solutions and adaptive products based on the characteristics of the measuring medium you need to transport& emsp;  Gear metering pumps have been widely used in the molecular distillation industry. Molecular distillation pumps and high vacuum discharge pumps have been recognized by industry insiders& emsp;  Today, Shandong Fucheng Hydraulic Editor will explain to you the working principle of molecular distillation:& emsp; Molecular distillation is a special liquid-liquid separation technique that differs from traditional distillation in that it relies on the principle of boiling point difference for separation. Instead, it achieves separation by the difference in the average free path of molecular motion of different substances& emsp;  When a liquid mixture flows along a heating plate and is heated, light and heavy molecules will escape from the liquid surface and enter the gas phase. Due to the different free paths of light and heavy molecules, the movement distance of molecules of different substances after escaping from the liquid surface is different. If a condensation plate is properly set up, light molecules can be condensed and discharged when they reach the condensation plate, while heavy molecules cannot reach the condensation plate and are discharged along the mixed liquid. In this way, the goal of material separation is achieved& emsp;  The pressure difference between the boiling film and the condensation surface is the driving force for the flow of steam, and even small pressure drops can cause the flow of steam. Running at 1mbar requires a very short distance between the boiling and condensing surfaces, and a distiller made based on this principle is called a short-range distiller. The short-range distiller (molecular distillation) has a built-in condenser located opposite the heating surface and reduces the operating pressure to 0.001 mbar& emsp;  The short-range distiller is a thermal separation technology process that operates at a pressure of 1~0.001mbar. Its lower boiling temperature is very suitable for thermosensitive and high boiling point substances. Its basic components include a cylindrical body with a heating jacket, a rotor, and an internal condenser; Accurately install a scraper and anti splash device on the fixed bracket of the rotor. The built-in condenser is located at the center of the evaporator, and the rotor rotates between the cylindrical body and the condenser& emsp;  The short-range distiller consists of an externally heated vertical cylindrical body, a central condenser located at its center, and a scraper rotating between the distiller and condenser& emsp;  The distillation process is as follows: the material is added from the top of the evaporator, and is continuously and uniformly distributed on the heating surface through the material liquid distributor on the rotor. Then, the scraper scrapes the material liquid into a very thin, turbulent liquid film and pushes it downwards in a spiral shape. During this process, the light molecules escaping from the heating surface are condensed into liquid on the built-in condenser through a short route and almost without collision, and then flow down the condenser tube and are discharged through the discharge tube located at the bottom of the evaporator; The residual liquid, i.e. heavy molecules, is collected in a circular channel under the heating zone and then flows out through the side discharge pipe& emsp;  The high precision of Huatai Precision Machinery Molecular Distillation Vacuum Discharge Pump is achieved through customized gaps, materials, and application processes, which can make the pumping process more efficient and stable.
