概述Overview 上海帕特泵业制造有限公司产生的螺杆泵是一种单螺杆输运泵，它的主要工作部件是偏心螺旋体的螺杆（称转子）和内表面呈双线螺旋面的螺杆衬套（称定子）。其工作原理是当电动机带动泵轴转动时，螺杆一方面绕本身的轴线旋转，另一方面它又沿衬套内表面滚动，于是形成泵的密封腔室。螺杆每转一周，密封腔中的液体向前推进一个螺距。随着螺杆的连续传动，液体以螺旋形方式从一个密封腔压向另一个密封腔，最后挤出泵体。 Screw pump is a single-screw transfer pump. Its main working parts include the screw of eccentric helicoids(called rotor)and the screw bush with a double-line helicoids on its surface(called stator). Its working principle goes like this: when the electromotor drives the pump shaft to rotate, the screw rotates around its own axes one hand and rolls along the inner surface of the bush on the other, thus forming a seal cavity in the pump. When the screw rotates a cycle, the liquid in the seal cavity will advance a screw pitch forward. With the continuous drive of the screw, the liquid will press from a seal cavity to another cavity in a spiral manner until it is pressed out of the pump body finally. 螺杆泵是一种新型的输送液体的机械，具有结构简单、工作安全可靠、使用维修方便、出液连续均匀、压力稳定等优点。我单位生产的浓浆泵凡接触物料的金属零件均选用优质不锈耐酸钢制作，轴材料2cr13 衬筒采用无毒无味的橡胶、工作温度可达100℃，可用于输送食品浆料和粘度10000泊斯卡•秒含有固体颗粒或胶块的溶液浆，悬浮液的腐蚀性介质。广泛用于食品、冶金、建筑、制药、化工等工业部门。 Screw pump is a new type of machinery for the liquid transfer. It boasts such advantages as simple structure, safe and reliable operation, easy operation and maintenance, continuous and uniform liquid discharge and stable pressure. The metal parts contacting materials of our underflow pump all adopt top-grade stainless acid-proof steel; the shaft material is 2cr13;the bush adopts nontoxic rubber with no peculiar smell; its working temperature can reach up to 100℃. It can be used for the transfer of corrosive media like foodstuff slurry, solution or suspension containing solid grains or rubber blocks with a viscosity of 10000Pa•s. It is widely applied in such industrial sectors as food, metallurgy, construction, pharmacy and chemical industry. 注意；螺杆泵所使用的介质不同应采用不同的橡胶。 Note: Different rubber for screw pumps using different media. 泵的安装Installation of Pump 根据泵的总图和说明书所提供的安装尺寸浇注基础和确定地脚螺栓的位置，一般情况下不宜改变进口方向。 The casting foundation and the positioning of the anchor bolt should conform to the installation dimensions included in the assembly drawing and the instruction manual of the pump. Generally the inlet direction should not be changed. 基础面应使用水平仪校平，待基础的水泥凝固后将泵装在基础上。电机轴和泵轴同轴度。两轴线偏移不超过±0.2毫米。倘若其轴线不重合，就会产生振动使轴承发热，甚至损坏泵。 The base surface should be adjusted flatly with the grad enter. The pump should not mounted on the base until the cement becomes solid. The motor and pump shafts should have a coaxially. The deviation of the two axes should not be beyond ±0.2mm. If the axes don′t coincide, the vibrancy will occur so that the bearing heats and the pump is even damaged. 泵的吸入和排出管道应有自己的支架，一般不允许泵体承受管路的重量，在泵处于倒罐工作时可以不装底阀，但应在吸入管路上装控制阀和过滤装置，以防杂物吸入泵内。泵安装在高于液面位置时，应在吸入管端装底阀，底阀喉口面积应大于吸入管截面积的百分之五十。 The suction and discharge pipelines of the pump should have their own brackets. Generally the pump body should not undertake the weight of the pipeline. It doesn’t matter not to mount the foot valve during the reloading of the pump, however, the control valve and the filter should be mounted on the suction pipeline to prevent the impurities from being sucked into the pump. When the pump is installed on the position higher than the liquid level, it is necessary to mount a foot valve on the end of the suction pipe and its throat area should be 50% larger than the sectional area of the suction pipe. 泵安装前一定要彻底清除管路内的杂物，如：焊渣、金属屑等，以免泵起动时被吸入造成事故。 Before the pump installation, it is necessary to remove the impurities in the pipeline thoroughly like welding slag and metal scraps lest they are sucked into the pump causing accidents when the pump starts. 泵的使用Usage of Pump 起动：1、准备必要的扳手和工具。 Start: Prepare required spanner and other tools. 2、检查机座，轴承和油腔无润滑油。 Check that there is no lubricating oil in the machine base, bearing and oil chamber. 3、检查空心轴和轴密封程度是否适当，填料压盖不可将盘根压得过紧，允许呈滴状渗出。 Check that the hollow shaft and its seal are proper and that the packing gland should not compress too tightly on the packing set and the drip leakage is allowed. 4、用手或管子钳转动联轴器，注意泵体内有无异物碰撞杂声和卡死现象，如有应清除后方可开车。 Turn the coupling with hand or tube spanner and check that there is no clash of foreign matters and jamming in the pump body. If any, remove them before starting. 5、将料液注满泵腔，切勿于摩擦运转，以免损坏衬套。 Fill the feed into the pump chamber and the frictional operation is not allowed to avoid the damages to the bush. 6、全开出液管的闸阀。 Open the gate valve of the liquid discharge pipe fully. 7、开电动机。 Start the electromotor. 停机：1、关闭吸入管阀门。 Stop: Shut off the valve for the suction pipe. 2、关闭排出管阀门。 Shut off the valve for the discharge pipe. 3、停止电机。 Stop the motor. 4、当泵处于长期停止工作时，应将泵腔内料液放净，并用水或蒸汽冲洗。 In case of disuse for a long time, it is necessary to discharge the feed in the pump chamber completely and wash it with water or steam. 运转：1、经常检查泵和电机轴承温升情况，最高温度不应超过75℃. Running: Check the temperature rise of the pump and motor bearings often whose max. temperature should not exceed 75℃. 2、及时补充润滑油，保证需要轴承润滑良好。 Fill in the lubricating oil in time to ensure good lubrication performance of the bearing. 3、运转过程中，如发现异常噪声或过大振动应立即停机检查，排除故障。 In case of abnormal noise or excessive vibrancy during the running, it is necessary to stop the machine immediately to check and remove the faults. 4、当流量显著减少，说明橡胶衬套已磨损，应更换新衬套后再运转。 The noticeable decrease of the flow shows the rubber bush is worn-out, so a new bush should be replaced for the operation. 应用范围举例Examples of Application Scope 本系列浓浆泵接触物的零件均选用优质不锈钢，螺杆衬套用中硬度橡胶制作，因而本泵最适用于食品加工行业和制药、化工等行业使用。例如： The parts contacting materials of this series of underflow pump all adopt top-grade stainless steel and the screw bush is made of medium-hardness rubber, so it is very suitable for such industries as food processing, pharmacy and chemical industry.
