Description
技术领域technical field
本发明涉及离心泵叶轮旋转抛光装置，尤其是一种离心泵叶轮复合式旋转抛光装置。The invention relates to a centrifugal pump impeller rotary polishing device, in particular to a centrifugal pump impeller compound rotary polishing device.
背景技术Background technique
目前，国内大部分离心泵叶轮仍采用传统的砂型铸造工艺，叶轮表面通常较为粗糙。而叶轮作为离心泵的核心部件，其粗糙度对机组的性能有较大的影响。降低叶轮表面的粗糙度对减小叶轮内的水力损失，提高机组效率具有重大作用。为提高过流部件表面的质量等级，需要对叶轮进行抛光。采用传统手工工艺对叶轮进行打磨抛光时，由于叶片是三维扭曲的曲面，力度及方向不易控制，对钳工操作技能要求较高，抛光效率也较低。特别是对于流道较窄的闭式叶轮，手工抛光难度非常大。At present, most domestic centrifugal pump impellers still use the traditional sand casting process, and the impeller surface is usually rough. The impeller is the core component of the centrifugal pump, and its roughness has a great influence on the performance of the unit. Reducing the surface roughness of the impeller plays a major role in reducing the hydraulic loss in the impeller and improving the efficiency of the unit. In order to improve the quality level of the surface of the wetted part, the impeller needs to be polished. When grinding and polishing the impeller by traditional manual techniques, since the blade is a three-dimensionally twisted surface, the strength and direction are not easy to control, and the requirements for the fitter's operation skills are high, and the polishing efficiency is also low. Especially for closed impellers with narrow flow passages, manual polishing is very difficult.
磨粒流加工是利用携带的粘弹性基体介质(研磨介质)在一定压力下反复摩擦加工表面而达到抛光作用的特种加工。磨粒流加工中磨料的化学性质不活跃而且无腐蚀性，零件材料是通过磨削方式被去除，工件表面的切削力低，经过研磨以后，表面基本不会留有应力。磨粒流去除材料非常干净，工件表面有瑕疵的地方，不会留下其他的杂质来填平，不同材质的工件可以使用同一磨料来加工，从一个工件上去除的材料，不会黏附或者镶嵌在其它的表面上。但是，现有的离心泵叶轮抛光装置，需要磨粒搅拌设备，管路连接也较多，装置结构复杂、体积较大、成本较高。Abrasive flow processing is a special processing that uses the carried viscoelastic matrix medium (grinding medium) to rub the surface repeatedly under a certain pressure to achieve polishing. The chemical properties of the abrasive in abrasive flow machining are inactive and non-corrosive. Part materials are removed by grinding, and the cutting force on the surface of the workpiece is low. After grinding, there is basically no stress left on the surface. Abrasive flow removes materials very cleanly. Where there are flaws on the surface of the workpiece, no other impurities will be left to fill them up. Workpieces of different materials can be processed with the same abrasive. The material removed from a workpiece will not stick or inlay on other surfaces. However, the existing centrifugal pump impeller polishing device requires abrasive stirring equipment, and there are many pipeline connections, the device has a complex structure, a large volume, and a high cost.

进一步，所述传动轴包括底部传动轴和顶部传动轴，所述底部传动轴与筒体之间由填料进行密封，所述底部传动轴的上端与叶轮通过叶轮轴套和叶轮螺母固连；所述叶轮轴套的作用是通过更换相应叶轮轴套，以便于不同孔径尺寸的叶轮与底部传动轴连，所述叶轮轴套与底部传动轴通过螺纹连接，螺纹旋向与所述叶轮旋转方向一致以避免松动，所述叶轮轴套上开有键槽以固连所述叶轮。Further, the transmission shaft includes a bottom transmission shaft and a top transmission shaft, the bottom transmission shaft and the cylinder are sealed by packing, and the upper end of the bottom transmission shaft is fixedly connected to the impeller through the impeller bushing and the impeller nut; The function of the impeller bushing is to replace the corresponding impeller bushing so that the impellers with different aperture sizes are connected to the bottom transmission shaft. The impeller bushing and the bottom transmission shaft are connected by threads, and the thread direction is consistent with the rotation direction of the impeller. In order to avoid loosening, key grooves are provided on the impeller sleeve to securely connect the impeller.
再进一步，所述叶轮口环间隙为3～5mm，以避免口环间隙过小，颗粒对叶轮口环处过度抛光，发生磨蚀；所述口环通过螺钉固连在稳流器出口处，与叶轮相配合，所述口环的内径尺寸为多个，且可根据不同叶轮尺寸更换相应尺寸的口环，以保证叶轮口环间隙为3～5mm；所述挡板通过螺钉固连在稳流器出口外侧，并成一定角度向下倾斜，以避免磨粒停留在挡板上侧，挡板与叶轮前盖板之间形成过流通道。Still further, the gap between the mouth ring of the impeller is 3-5mm, so as to avoid the gap of the mouth ring being too small, and the particles will over-polish the mouth ring of the impeller, causing abrasion; The impeller is matched, and the inner diameter of the mouth ring is multiple, and the mouth ring of the corresponding size can be replaced according to different impeller sizes to ensure that the clearance of the impeller mouth ring is 3-5mm; the baffle is fixed on the steady flow by screws It is outside the outlet of the impeller and slopes downward at a certain angle to prevent abrasive particles from staying on the upper side of the baffle, and a flow passage is formed between the baffle and the front cover of the impeller.

本发明的技术构思为：整个装置总共有两台电机，两个传动轴，电机通过联轴器与传动轴连接。所述装置下面部分的电机通过底部传动轴带动叶轮旋转，叶轮通过叶轮轴套和叶轮螺母与底部传动轴连接，当叶轮转动时产生的离心力会驱使叶轮内的流体从叶轮出口流出，同时在叶轮进口产生一个低压区，将水吸进去。装置所用流体是一种磨粒流，即流体中带有一些研磨介质，叶轮转动的时候，叶轮周围和内部的流体会对叶轮表面进行打磨、抛光、去掉毛刺。为避免口环间隙过小颗粒对叶轮口环处过度抛光，叶轮口环间隙为3～5mm；由口环间隙流过的流体，其磨粒由于叶轮的旋转作用会在叶轮前盖板与挡板形成的通道内往复碰撞反弹，直至流出该通道，这样就加强了磨粒对前盖板的抛光作用。当流体流出叶轮，带有一定动能的流体会沿着流道向上，进入储水槽，储水槽固定在筒体上面，储水槽下面安装了一个稳流器，储水槽内的流体向下流入稳流器，最后流入叶轮进口，实现一个循环。装置上面的电机固定安装在支架上，电机通过联轴器与传动轴连接，传动轴再与筒体通过螺栓连接，与筒体连接的顶部传动轴和与叶轮连接的底部传动轴在同一条竖直中心线上。当叶轮工作一段时间之后，流体中的磨粒已经基本分布均匀，导致叶轮周围的磨粒浓度降低，抛光的效率和效果会降低。为了解决这种情况，这时候需要将叶轮停下来，然后开启装置上侧的电机，带动筒体转动，由筒体的旋转沉降作用提高中间叶轮周围的磨粒浓度。The technical idea of the present invention is: the whole device has two motors and two transmission shafts in total, and the motors are connected with the transmission shafts through shaft couplings. The motor in the lower part of the device drives the impeller to rotate through the bottom transmission shaft, and the impeller is connected to the bottom transmission shaft through the impeller bushing and the impeller nut. When the impeller rotates, the centrifugal force will drive the fluid in the impeller to flow out from the outlet of the impeller, and at the same time The inlet creates a low pressure zone that sucks water in. The fluid used in the device is an abrasive particle flow, that is, the fluid contains some abrasive media. When the impeller rotates, the fluid around and inside the impeller will grind, polish, and remove burrs on the surface of the impeller. In order to avoid excessive polishing of the impeller mouth ring by particles with too small mouth ring clearance, the impeller mouth ring clearance is 3-5mm; the abrasive particles of the fluid flowing through the mouth ring clearance will be on the impeller front cover plate and the baffle due to the rotation of the impeller. The reciprocating collision and rebound in the channel formed by the abrasive plate until it flows out of the channel, thus strengthening the polishing effect of the abrasive grains on the front cover. When the fluid flows out of the impeller, the fluid with a certain kinetic energy will go upward along the flow path and enter the water storage tank. The water storage tank is fixed on the cylinder body. A flow stabilizer is installed under the water storage tank, and the fluid in the water storage tank flows downward into the steady flow. device, and finally flows into the impeller inlet to realize a cycle. The motor on the device is fixedly installed on the bracket. The motor is connected to the transmission shaft through a coupling, and the transmission shaft is connected to the cylinder through bolts. The top transmission shaft connected to the cylinder and the bottom transmission shaft connected to the impeller are on the same vertical line. straight centerline. After the impeller works for a period of time, the abrasive particles in the fluid are basically evenly distributed, resulting in a decrease in the concentration of abrasive particles around the impeller, and the efficiency and effect of polishing will be reduced. In order to solve this situation, it is necessary to stop the impeller at this time, and then turn on the motor on the upper side of the device to drive the cylinder to rotate, and the rotational settlement of the cylinder increases the concentration of abrasive particles around the middle impeller.
本发明的有益效果主要表现在：1、本发明提供了一种离心泵叶轮复合式旋转抛光装置，装置内可实现自循环，节约打磨抛光成本，降低人力物力。2、本发明设计了一种可转动的筒体，可以使磨粒沉降到叶轮周围，使叶轮的打磨、抛光更加高效。3、本发明装置结构简单、紧凑、操作方便、使用寿命长，且抛光效果好，降低了制造和使用成本。The beneficial effects of the present invention are mainly manifested in: 1. The present invention provides a centrifugal pump impeller compound rotary polishing device, which can realize self-circulation in the device, save the cost of polishing and polishing, and reduce manpower and material resources. 2. The invention designs a rotatable cylinder, which can make the abrasive particles settle around the impeller, making the grinding and polishing of the impeller more efficient. 3.
