Problems solved by technology

[0002] At present, the existing buffers for industrial water pumps adopt the piston structure of the oil system. In order to achieve the effect of timely delivery of the weaving beam, the piston is drilled with an oil guide hole to connect the upper and lower oil chambers to speed up the response of the buffer; The buffer lacks adjustability and cannot adapt to the response speed requirements of the let-off mechanism for different cloth products; at the same time, due to the faster response speed of the buffer, it is easy to cause obvious gaps on the cloth during the weaving process, which greatly affects the cloth. poor textile quality, resulting in a waste of raw materials and an increase in cost
