Small batch spandex spinning test device

Abstract

Small-batch spandex spinning testing apparatus comprises a storage tank and spinning metering pumps. A feed pipe is arranged on the upper portion of the storage tank, a discharge pipe is arranged at the bottom of the storage tank and provided with a gear booster pump, one end of the gear booster pump is connected with the spinning metering pumps, the other end of the gear booster pump is connected with a motor arranged on a support, filters are arranged on conveying pipelines between the gear booster pump and the spinning metering pumps, a pressure sensor is arranged on a conveying pipeline between the filters and the spinning metering pumps, a tee joint is arranged on a conveying pipeline between the pressure sensor and the filters and connected with the storage tank through a bypass valve, and the pressure sensor, the motor and the bypass valve are all connected with an electrical controller. The small-batch spandex spinning testing apparatus is provided with the storage tank and the gear booster pump, so that stable extrusion is achieved; the filters and filter screens are arranged, so that spinning quality and efficiency are improved; the filters are connected in parallel and are convenient to replace accordingly; the pressure sensor is arranged to detect internal pressure of the pipelines; the bypass valve is arranged, so that it is guaranteed that pipeline pressure is in a process safe range when the device is operated.

Description

technical field [0001] The invention relates to a textile equipment, in particular to a small-batch spandex spinning test device. Background technique [0002] For a long time, domestic spandex has mainly relied on the overall imported technology. Domestic manufacturers have been slow to improve the original technology and develop new spandex products while digesting the imported technology. Considering, therefore, the small-batch aggregate yield cannot be used alone. At the same time, since the spinning process adopts the design method of the whole line with the same process, it cannot meet the single number test of small batch spandex spinning. If the whole production line is used for the test, the test cost will be too high, and the cost of raw materials and energy will be too high. The loss is serious, and the output is greatly reduced, and the process cannot be adjusted independently, which further increases the cost of research and development. In this case, it is ne...

Problems solved by technology

The device can be disassembled and moved, occupying a new space. The distance between the polymer from the reaction site to the use site is relatively long, and the use site is affected by the test or research and development, and there is uncertainty in the position. Therefore, the polymer is not suitable for automatic transfer and needs to be manually transferred. The polymer is transferred to the place where the device is placed by means of manual transfer, which leads to high labor intensity, long labor time and low efficiency
