1.如泵轴高出泵管,可用图1打捞器捞取,半月活门(图2)锥形孔小头直径比泵轴直径小3～5毫米,当泵轴穿过半月活门后,提升打捞器,活门卡住泵轴,即可将泵吊出井外.如泵轴头与泵管一样平或低于泵管,用图3打捞器捞取,原理同前,使用时将图右侧机构放进图左的圆筒中即可.(陕西风翔县范家塞公社大沙凹农修厂梁正芳)2.如泵轴头与泵管一样平或低于泵管用图4示打捞器,待此打捞器下到掉泵位置时要慢放,让定位爪扶正泵管,当泵管法兰顶开抓紧爪后,抓紧爪在弹簧
1. If the pump shaft is higher than the pump tube, use Figure 1 salvage fishing, half-moon valve (Figure 2) cone head diameter smaller than the shaft diameter of 3 to 5 mm, when the pump shaft through the half-moon valve, raise the salvage The valve stuck pump shaft, the pump can be hoisted out of the well, such as the pump shaft and the pump tube as flat or lower than the pump tube, with the salvage fishing in Figure 3, the same principle with the former, the figure will be used when the right body release Into the left cylinder into the map. (Shaanxi Fengxiang County Fan Jiasong commune Dasha Au farming repair plant Liangzheng Fang) 2. If the pump head and the pump tube as flat or lower than the pump tube Figure 4 shows salvage, to be The salvage device to the pump position to slow down, so that the positioning pawl righting pump tube, when the pump pipe flange to open the claw claw, gripping claws in the spring
