G-type single screw pump has become one of the important equipment in environmental protection, papermaking, petroleum, chemical, shipbuilding and other fields due to its own advantages of low noise and energy saving, and has played an active role in improving work efficiency. However, the sealing performance of the single screw pump still needs to be improved so as not to affect the lifting capacity of the screw pump.
In order to effectively improve the sealing performance of the G-type single screw pump, the interference can be increased appropriately. The interference mainly refers to the size of the interference fit between the metal rotor and the stator rubber bushing. In specific work, there should be a certain amount of interference between the stator and the rotor to ensure the tightness between the enclosed chambers.
Therefore, the interference between the stator and the rotor will greatly affect the performance of the equipment. Generally speaking, under the premise that the number of stages is constant, the magnitude of interference directly determines the load-carrying capacity of the cavity and affects the lifting capacity. Therefore, with other parameters unchanged, a single screw pump with a larger interference can be used. Improve its overall sealing performance and increase pressure, thereby expanding its scope of application. At the same time, an electric screw pump can be actively introduced in the production process to prevent fluid flow, thereby reducing its operating efficiency during complex mechanical manufacturing.
Secondly, you can choose a material with higher hardness. Hardness is the main factor affecting the deformability of a material. The larger the elasticity value, the easier the corresponding material deformation. It can be seen from the experimental data that the modulus of elasticity increases with the increase in hardness, which should take into account its influence on the sealing performance of the single screw pump. Therefore, the single screw pump technicians of Zoomlian Pumps believe that a screw pump stator made of rubber with higher hardness should be selected to improve its sealing performance.
In addition, the optimized G-type single screw pump structure and parameters are kept in a reasonable state, and the sealing performance of the single screw pump rubber bushing is mainly affected by the structure, resulting in volume compression deformation and collective shape deformation. The screw pump system can be reasonably optimized to achieve the purpose of improving the sealing performance of the screw pump
