for different purposes, accounting for about 20% -30% of the total amount of machinery and equipment of ships, marine pump prices in the marine equipment costs the proportion is relatively large. Of the total cost, the marine pump about 4% to 8% of the total cost of the ship equipment, under normal circumstances. Marine pump purchase a medium-sized vessels of up to 10 million yuan or more.?Diesel high-pressure pump to adjust the fuel supply timing????Diesel exhaust temperature, whether rough work, eat a load capacity of size, mobility, economy and a number of factors, such as quality and sophistication ventilation, turbocharger performance, fuel injector, cylinder and piston rings wear, the timing and the supply of high-pressure pumps, fuel quality and the like. When the diesel engine performance slip, but exclude the impact of other factors, it would be necessary for high-pressure pumps and reasonable adjustments. Of course, the need to be checked before adjustment. Check the method varies by model, pump type to another. We have Maoyou common law, light law and notation.?????Mao law. Maoyou method is suitable for any model or type of oil pump timing checks.Removing either a cylinder pressure tubing connected to the high-pressure pump outlet valve, the high pressure pump and into the pipeline system filled with fuel. Slow disk drive, when the oil began to write down the flywheel transient fluctuation scale, that is, the cylinder fuel supply time, repeated (at least three times) and averaged, that is the cylinder injection timing. That method of measuring fuel supply advance angle.?????Photopheresis. Large end section back to the hole injection pump, if the sleeve motivated, back hole of equal height, remove the screws on the corresponding pump. With the light back to the hole and screw hole cover moments, remember the oil supply from the moment of the flywheel scale.?????Notation. Some of the high-pressure pumps in the pump and the pump column are engraved with a horizontal line, plate car, as long as the two lines is the oil agreement in time, read from the flywheel dial.?Improve fuel pressure of the injection to achieve the best atomization, high-pressure pump main purpose is as a jack, upsetting head, pinch the power source machine, embroider machine hydraulics.????High-pressure pump installation sequence: In the high-pressure pump installed in the process, in order to avoid the debris to fall into the machine, all the units should cover the perforations. The crew on the buried anchor bolts, based on the base and intermediate base with a pair of wedge pad for correction. Proofreading pump shaft and motor shaft concentricity, on the road linking the outer circumference of the shaft, you can have 0.1 mm deviation; two coupling plane gap should ensure that in 2 to 4 mm, (a small pump to take a small value) gap to uniform, tolerance 0.3 mm. After the connected piping and determine the motor direction of rotation, connect the coupling, and aromatic again continue proofreading concentric shafts. After the unit trial run 2 to 3 hours, do a final check, if no adverse phenomenon, is considered qualified to install. In the commissioning process, check
