Tai tell you if a gear pump is broken how to fix?

1, revised gear pump gear pump driving shaft and bushing wear after driving shaft and bushing wear, the gap increased its cooperation, will affect the fuel pump. In case of this, the method can be used to repair the driving shaft or bushing rehabilitation of its normal cooperation voids. If the active shaft wear subtle, just press out the old bushings replaced after standardized scale bush, cooperation can be recovered to allow the size of the gap. If the driving shaft and bushing wear serious gaps and cooperation when severe cost overruns, do not just replace the bushings, and a drive shaft also use chrome or oscillation welding method will increase its diameter, and then grinding to a standardized scale, rehabilitation and bush The cooperation needs. 2, repair the pump housing cavity pump gear pump housing cavity wear, which usually takes the lumen casement law amendments, the rows lining the lumen of the large rear set with cast iron or steel liner. After casement, lining the cavity 3, after the gear pump drive shaft repair gear pump driving shaft bushing hole bushing hole with the driven shaft bore wear wear, available reaming method to eliminate signs of wear, and is equipped with a corresponding increase to bush scale. Also driven shaft bore wear reaming method to eliminate signs of wear, and then press reaming hole practice after the driven shaft 4 scale manufacturing, housing repair cracks crack repair housing smooth gear pump pump housing nickel-copper-free cast 508 electrode welding. Weld must be strict and Yuan pores, and pump cover contact surface flatness error of not more than 0.05 mm. 5, repair gear pump pump cover repair work plane: If gear pump pump cover work wear small plane, grinding technology available to eliminate signs of wear, namely put a small amount of sand in the channel valve or thick glass, and then put the pump cover In the above grinding until eliminate signs of wear, the appearance of a flat stop work. When the pump cover operation plane exceed 0.1 mm wear depth, it should be adopted after the first grinding method of turning correction. Our main products are: screw, stainless steel gear pumps, gear pumps, rotary pump, oil pump series. http://www.clb678.com
