TaiBang DHB ignition parts wear each pump solutions
TaiBang DHB ignition pump application has been quite extensive , mainly used in cement , furnace boilers , thermal coal , glass thermoelectric, rubber tires , mixer , gas plants, coal , diesel and heavy oil as well as fuel delivery , hydraulic engineering, marine engineering, petrochemical and other industries. There will be some failures along the pump , these are normal, the same thing can be said for any length of time will have problems , it is inevitable ! But fails, how do we solve it must grasp ! Following describes a few kind of failure , how to solve :
DHB ignition pump with increased use of time , there will be insufficient oil pump , oil pump failure even , mainly because the relevant parts of the excessive wear . Wear parts ignition pump drive shaft and bushing are mainly passive gear shaft center hole and the pin , the pump chamber and the gear housing , the gear end and the pump cover . When the oil pump wear its main technical indicators meet the requirements, it should disassemble , identify the location and extent of wear and take appropriate approach to be repaired.
Ignition shell cavity pump repair : the pump housing cavity wear, coal tar pump cavity casement law generally taken to repair , after the upcoming big cavity inlaid with enamel cast iron or steel bushings . After casement , boring into the cavity size requirements , and the end face of the bushing extending rubbed off , so the joint surface is flush with the casing .
DHB ignition pump repair work plane : If the pump cover work wear smaller plane , hand- grinding method can be used to eliminate signs of wear , that put a little sand valve on the platform or thick glass, and then on top of the pump cover grinding , coal with the growth of the oil pump time , there will be insufficient oil pump , oil pump failure even , mainly because the relevant parts of the excessive wear . Wear parts ignition pump drive shaft and bushing are mainly passive gear shaft center hole and the pin , the pump chamber and the gear housing , the gear end and the pump cover . When the oil pump wear its main technical indicators meet the requirements, it should disassemble , identify the location and extent of wear and take appropriate approach to be repaired. Ignition pump repair work plane : If the pump cover working plane wear small, hand- grinding method can be used to eliminate signs of wear , that put a little sand valve on the platform or thick glass, and then on top of the pump cover is polished until signs of wear eliminate work surface is flat so far. When the pump is working flat cover wear depth more than 0.3 mm , should take the first turning grinding way to repair . Wear it to the driven shaft hole reaming method to eliminate signs of wear , and then press the actual size of the hole after reaming formulated driven shaft .
DHB ignition pump drive shaft and bushing wear, with the gap increases, will affect the fuel pump . If this method of repair drive shaft or bushings can be restored to its normal with the gap . If the drive shaft wear light , just press out the old bushings replaced standard size bushing , with the gap will return to the allowed range. If the drive shaft and bushing wear serious and the gap with the seriously overweight , not only to replace coal tar pump bushings, and drive shaft also applied chrome or vibration welding method to increase its diameter , and then grinding to a standard size, recovery with the requirements of the liner . Repair cracks in the housing repair oil pump housing : housing 508 crack available nickel-copper rod casting welding . Weld must close and Yuan pores, combined with the pump cover surface flatness error of less than 0.05 mm . Repair the drive shaft bushing hole : the same drive shaft housing repair and drive shaft bushing bore hole pump cover wear bushing wear repair methods .
