New Common Rail Fuel Injector Nozzle Dsla144PV605 & V0605p144 for Injector 5ws40148-Z 5ws40007 2s6q-9f593-Ab & AC A2c59513997

In addition, a final test procedure of the workpiece being processed is added to the machining system, thus implementing closed-loop control function, which can make the nozzle machining to a specified flow rate. The grinding of the thin liquid flow can stop the machining of the nozzle at any expected flow point.

Compared with the hydraulic extrusion grinding another advantage is that the medium viscosity is very low, so it is easy to wash off from the small hole and will not remain in the spray hole, so the cleaning after processing is much more convenient than the hydraulic extrusion grinding. The DYNET-ICS machine, like the Extruder machine, is expensive, costing around $200,000 for a small batch of machines.

The technology room of the oil pump and nozzle Research institute in Wuxi adopts the pressure chamber of the needle valve body for EDM processing. By changing the flow direction of the EDM processing medium, the burr at the junction of the pressure chamber and the nozzle is removed, and the radius of the nozzle inlet is 0. For the purpose of rounding the corner of 03~0.07, the flow value of the nozzle increases obviously after processing by this method, about 10~ ~ 20%. Taking the oil nozzle used in Wuxi Diesel Engine Plant 6110 diesel engine as an example, three batches of oil nozzle couple parts were processed, and the average flow rate was increased by 15.8%. The dispersion of traffic also decreased from more than 10% to less than 5% for taxis. The attached table shows the flow data of a batch of nozzle processed by a 0.29 nozzle drill bit in a factory. The actual shrinkage hole after heat treatment is about 0.015mm.
