液压泵配油盘严重磨损后，将使其高、低压腔间被击穿。轻者产生热量、消耗功率、使密封件老化、油温升高，缩短机器的使用寿命；重者将导致液压系统不能工作。一个很简单的应急修复方法，虽没有使用高精度的专用平面磨床，但修复的效果却很理想。具体方法如下： 1所需材料 80目、180目的氧化铝气门研磨砂各1盒，120#、200#的粗、细水砂布各10张，机油2kg左右，圆形平面{yj}磁铁（可用100瓦音箱喇叭的磁铁）1块，钢板（200mm×200mm×10mm），平板玻璃（400mm×400mm×5mm）1块，清洗用汽油10kg左右，以及毛刷、油盆等。 2操作方法 （1）粗磨。选将120#粗水砂布放在平板玻璃上并加少许机油和80目研磨砂，再将配油盘平放在水砂布上进行平磨。平磨的手法是：边磨边转，轨迹呈“8”字形。平磨的程度是基本上xx其大与深的沟槽。 （2）细磨。用与上面同样的方法，使用120#细水砂布对动、配油盘进行平磨，直至xxxx其所有的沟漕为止。 （3）精磨。用{yj}磁铁将动配油盘吸住，再将{yj}磁铁平吸到钢板上（此时，配油盘相当于一定位平台，既能起到对动配油盘定位的作用，又能使动、定配油盘研磨均匀，且对研磨手法的要求不严），将180目的研磨砂与机油调匀后涂到配油盘，轻轻放到配油盘上（因配油盘有吸力，要小心轻放），手不能下压，xx利用磁铁的吸力进行配磨。手法还是边磨边转，轨迹呈“8”字形。当磨到动、配油盘的表面无印痕后，再涂机油于配油盘上，并用同样的方法研磨20min左右，精磨工作就完成了。{zh1}用退磁器将配油盘剩磁退掉即可。 （4）检验。用汽油将配油盘清洗干净，在平板玻璃上涂上一层黄油，将配油盘放在涂有黄油的平面上（黄油是防止配油盘与玻璃板之间漏油），再将干净汽油加入配油盘的高、低压配油孔中，看配油盘和高压腔与低压腔之间是否漏油，如果没有明显漏油，即符合精度要求。

Pump oil pan with serious wear and tear, will make it high and low pressure chamber is the breakdown between. Light by heat, power consumption, so that the aging seals, oil temperature increased to shorten the service life of the machine; weight will cause the hydraulic system does not work. Emergency repair of a very simple method, although not exclusive use of high-precision surface grinder, but the effect is very good repair. Specific methods are as follows: 1 Materials needed 80 mesh, 180 purpose of research and grinding of alumina and 1 valve boxes, 120 #, 200 # of coarse and fine emery cloth all 10 water, oil 2kg or so, round flat permanent magnet (available 100-watt speaker speaker magnets) 1, steel plate (200mm × 200mm × 10mm), flat glass (400mm × 400mm × 5mm) 1 block, clean gasoline around 10kg, and brush, oil bowls. 2 How (1) coarse grinding. 120 # electoral coarse emery cloth on the flat on the water and add a little oil and 80 research projects scrub, then oil pan flat on the water with emery cloth on flat ground. Flat grinding means is: edging turn, track was "8" shape. The degree of grinding is basically to eliminate the large and deep trench. (2) fine grinding. Using the same method as above, using 120 # fine emery cloth to the moving water, with oil pan to level ground until the complete elimination of all of its grooves up. (3) fine grinding. With a permanent magnet to move with oil pan suck, and then breathe a permanent magnet flat steel plate (At this point, with oil pan is equivalent to a positioning platform, both played on the dynamic role of positioning with oil pan, they can move , will be grinding with oil pan evenly, and the strict requirements of the grinding technique), the purpose of study 180 after grinding and oil and mix thoroughly coated with oil to the plate, gently place with the oil pan (oil pan with a suction due to Handle with care), the hand can not be under pressure, full use of magnets with suction to wear. Tactics, or edging turn, track was "8" shape. When the ground to move, with no imprint the surface of oil pan after, and then cover with oil in the oil pan, and is used in the same way about 20min grinding, grinding work is complete. Finally, with oil pan back porcelain will remanence can be drained away. (4) testing. Used gasoline to clean with oil pan, the flat glass coated with a layer of butter, will be equipped with oil pan coated with butter on the plane (butter with oil to prevent oil leakage between the plate and glass), then a clean Gasoline join with trays of high and low pressure with oil hole, the look with oil pan and high-pressure chamber and the low pressure chamber is between the oil spill, if there is no significant oil spills, that meet the accuracy requirements.
