鳌牌水力挖塘机组是用水力机械改造、新建鱼池的渔业机械,也可用作挖河渠水利工程、化工排污工程、建筑工程等行业的土方作业。北京农机学院、江苏泰兴县渔机厂,经过一年多的努力,对原机组进行了改进提高设计。主要是高压冲水系统中的高压泵和喷枪,共设计出三种型式,扩大了机组的使用范围,配套趋于合理,能耗降低,工效提高。新设计的三种高压水泵均达到了预期技术指标,其中80—50—200型高压泵按ISO国际标准设计。喷嘴采用了多元金属共渗新工艺处理,耐磨性能提高。对泥浆泵轴封装置进行了探索,试验运转1494小时后仍未损坏,提高了使用寿命。电控装置比原机组更加安全。主要技术参数 1.NL100—160型立式泥浆泵:配套功率13千瓦电机,扬程16米,流量140米~3/时,出口直径100毫米。
Ao license hydraulic digging pond unit is a hydraulic machinery transformation, the new fish pond fishery machinery can also be used as digging canal water conservancy project, chemical sewage works, construction and other industries earthwork. Beijing Agricultural Machinery Institute, Taixing County, Jiangsu Fishery Factory, after more than a year of hard work, the original unit has been improved to improve the design. Mainly high-pressure flushing system in the high-pressure pump and spray gun, designed a total of three types, expanding the use of units, supporting tend to be reasonable, reduce energy consumption, improve work efficiency. The new design of the three high-pressure water pumps have reached the expected technical indicators, including 80-50-200-type high-pressure pump designed according to ISO international standards. Nozzles using a new multi-metal processing infiltration process, wear resistance increased. The mud pump shaft seal device was explored, the test operation is still not damaged after 1494 hours, improve the service life. Electronic control device more secure than the original unit. Main technical parameters 1.NL100-160 Vertical Mud Pump: Supporting power 13 kW motor, head 16 meters, flow 140 meters ~ 3 / hour, the export diameter of 100 mm.
