螺杆泵的特点是结构简单、体积小、噪声低、工作平稳、流量的脉动性能好、寿命长。我厂生产的H_3LB螺杆泵是给本厂生产精密外圆磨床配套用的,一九六五年开始生产。开始时用成型刀进行车削加工,劳动强度大、效率低、刀具容易磨损,换刀校正困难。由于高精度外圆磨床的产量不断增加,用成型刀车削的办法远远跟不上需要,于是我们进行了技术革新,在工人与技术员的密切配合下,制造出如图1所示的螺杆加工专 Screw pump is characterized by simple structure, small size, low noise, stable work flow pulse performance, long life. I H_3LB screw pump factory production is to support the production of precision cylindrical grinding machine used in 1965 to begin production. The beginning of turning with a forming knife, labor-intensive, low efficiency, easy to wear knives, tool change correction difficult. As the production of high-precision cylindrical grinding machines continues to increase, the method of turning with the forming knife is far behind the need, so we conducted technological innovations and worked closely with the workers and technicians to manufacture the screw as shown in Figure 1 Specialized
