Abstract

The invention relates to a high-voltage-resistant uniform solution supply device for large-scale electrostatic spinning. The high-voltage-resistant uniform solution supply device for large-scale electrostatic spinning comprises a pump body, and further comprises a vacuum insulating cover and a negative-air-pressure suction device, wherein the pump body is a cycloidal gear pump; the pump body is positioned in the closed space in the vacuum insulating cover; the vacuum insulating cover communicates with the negative-air-pressure suction device; all cycloidal gear pumps are connected in series; one cycloidal gear pump at an end is connected with a motor through an insulating linkage rod; and the motor and the insulating linkage rod are also positioned in a closed space inside the vacuum insulating cover. According to the high-voltage-resistant uniform solution supply device for large-scale electrostatic spinning, a vacuum insulating environment is constructed in a pump body equipment area, so that electrostatic breakdown can be effectively prevented, and loading of dozens of kilovolts or even hundreds of kilovolts in the electrostatic spinning production process can be met; an independent multi-linkage cycloidal gear pump is adopted to independently supply the solution to a spinning area, so that uniform and stable supply of a spinning solution is realized; and the high-voltage-resistant uniform solution supply device for large-scale electrostatic spinning can stably run under various working conditions, and is suitable for large-scale production of electrostatic spinning.
