How to Make the Installation of Fuel Injection Pumps 294000-0618

The process of installing a fuel injection pump, from the initial cleaning of the parts to the adjustment of the fuel supply advance angle, each step contains profound professional knowledge and rigorous operational specifications. In this article, we will introduce you to the installation steps and precautions of Fuel injection pumps 294000-0618, and hope that it will be helpful to you.

1. Cleaning preparation

(1) Thorough cleaning: Before installing the fuel injection pump, all parts should be thoroughly cleaned to prevent dirt and impurities from being brought into the pump body during installation, resulting in early wear of the parts.

(2) Special attention: the plunger sleeve and the pump body should not have metal shavings, sand and cotton fibers and other debris, in order to prevent oil leakage and damage to the parts.

2. Plunger sleeve installation

(1) Installation direction: the plunger sleeve must not be installed in reverse. Once installed in reverse, the plunger set of positioning screws will be on top of the oil inlet hole, affecting the normal engine ignition and combustion.

(2) Impact: After the plunger set is reversed, the oil feed and return of the plunger working stroke will only depend on the oil return hole, and the oil feed and return will be small and slow, affecting the performance of the engine.

3. Positioning screw and gasket installation

(1) Positioning screw

Length requirement: the positioning screw of the plunger sleeve should meet the requirements and should not be too long, otherwise it will make the plunger sleeve in the pump body be top crooked and affect the plunger movement.

Over-tightening problem: The positioning screw should not be over-tightened, otherwise the sleeve will be deformed and the plunger will be stuck.

Installation requirements: When the outlet valve is not installed, after tightening the positioning screw, the plunger sleeve can move up and down flexibly for a small distance, but without rotation.

(2) Gasket installation:

Copper gasket: do not miss the installation of the copper gasket of the positioning screw, and ensure that the seal here is good, otherwise it will cause serious oil leakage, resulting in air into the fuel injection pump, making the engine run erratically.

4. Fuel outlet valve seat gasket installation

(1) Gasket inspection:

High-pressure and low-pressure gasket: high-pressure sealing copper gasket and low-pressure sealing rubber gasket of the outlet valve seat must be carefully inspected before installation, and it is required to be intact and must not be missed.

Impact: damaged or missing gasket will lead to high-pressure oil cavity and low-pressure oil cavity connected, resulting in the oil pump can not work properly.

(2) Tightening torque: When installing the outlet valve tight seat, the tightening torque must be moderate to ensure that the plunger can move flexibly at any position in the plunger sleeve without localized stagnation.

(3) Gasket flatness: the gasket must be flat, such as uneven or wrinkled gaskets, the outlet valve seat tightening, the plunger sleeve is easy to unilateral force, accelerate the wear of the plunger coupling.

5. Oil supply advance angle adjustment

(1) Adjustment requirements: correctly adjust the fuel supply advance angle according to the specified requirements. Early or late fuel supply time directly affects the fuel combustion efficiency and engine power output.

(2) Impact: too early or too late fuel supply will lead to inadequate combustion, which in turn affects the engine's power, economy and emission performance.

(3) Adjustment method: After the fuel injection pump is installed, use special tools to make precise adjustment of the fuel supply advance angle to ensure that the engine can perform optimally under various working conditions.
