Spinning pump-an important component of chemical fiber spinning equipment
The spinning metering pump accurately measures the polymer solution or melt and delivers it evenly to the spinneret, requiring small size and precise structure, and sometimes high temperature resistance. Generally made of stainless steel. There are two kinds of gear pump and piston pump, most of which are commonly used in gear spinning pump.

The light and small rubber pump mainly relies on the conversion of electric energy into kinetic energy, and works up and down the stator and rotor to transport the liquid. The following methods should be followed when using.

1, the size of the extruded products to a smaller tolerance, so that the unit weight of the material to produce more products. When the dimensional tolerance of the extruded product is strict or the raw material cost of the product is more expensive, the use of a melt pump is more necessary and more valuable.

The gear pump is driven by an independent motor, which can effectively block the upstream pressure pulsation and flow fluctuation. The pressure pulsation at the gear pump outlet can be controlled within 1%. The use of a gear pump in the extrusion line can increase the flow output speed and reduce the shear and residence time of the material in the extruder.

Several problems encountered in the development of China's pump industry
In recent years, we have strengthened the pump industry's foreign exchanges and economic and trade exchanges, whether it is compared with foreign industries in the same industry, or relative to each other in our industry, we are facing problems and gaps, these problems I think are common, and in the future must be taken seriously.

New Progress of Foreign Chemical Fiber Test Equipment
The versatility of MAE micro-research equipment is good, and a variety of solvent systems can be selected, such as DMSO/DMAc/DMF, inorganic solvents including NaSCN/ZnCl2/nitric acid/ethylene carbonate and new ionic liquids. The wet spinning device can be configured with two forming methods, namely, the wet spinning process and the dry jet-wet spinning process.
