Fuel pump lecture
VE-type distribution fuel injection pump stuck cause analysis VE pump plunger, both the role of pressure oil and distribution work, the rotation speed of 1000-2000r/minm, each rotation of a pump oil 4-6 times, its cooperation The gap is only 3nm, a little careless, easily stuck. The stuck position is usually in two places. The first is the jam between the plunger and the sleeve. At this point, the plunger is likely to be broken. After the engine is extinguished, it can no longer be started. No oil is sprayed from the pump head, and the fueling door does not respond. The second is the jam between the plunger and the drain ring. When the drain ring works, it only slides on the surface of the plunger and does not rotate. Once locked, the ring rotates synchronously with the plunger, and the ball head on the speed governing lever assembly does not allow the ring to rotate. Therefore, in the strong slewing moment Under the effect, the ball head is squeezed and the lever assembly is forcibly twisted. At the moment of jamming, the positioning pin on the cam plate may be cut off. 1. Fuel contamination is the main cause of seizure (1) The presence of water-containing or corrosive liquids in the oil, mistakenly adding gasoline, low-quality diesel oil, etc., causes corrosion, damage to the lubricant film, and seizure. (2) The filter fails, and tiny hard particles enter the pump and cause jams. (3) The long-term operation of the oil pump is not maintained. Because the pump is installed on the side of the engine, it is often in a high temperature state. The hydrocarbon compounds in the fuel oil are cracked into tiny carbon particles and adhere to the wall of various parts. Over time, they gradually accumulate into tiny particles. Once the tiny particles, Entering high-speed running precision sports is also one of the causes of death. (4) The pump buffer rubber is long-term to withstand the impact of torque, and continue to withstand the impact of the load, easy to aging, easy to peel off after aging into small particles, these small particles once into the plunger cavity, it may make the plunger stuck . 2. Improper operation during commissioning is also one of the causes of jamming. The plunger rotates at high speed in the plunger sleeve. The lubrication and heat dissipation between the surfaces of the plungers is based on the small amount of fuel released during the pump oil distribution process. Once there is no oil leakage, Out, the plunger can not be cooled and lubricated, serious failures may occur. For example, when the solenoid valve is not energized during commissioning, or after the power is turned on, the electromagnet valve does not work; for example, when the oil stopping speed is adjusted, the test stand runs for a long time, and a large amount of fuel is leaked from the drain ring. Oil is pressed out of the dispensing hole. In this case, there is no oil lubrication and heat dissipation on the surface of the plunger and the sleeve, and it is very likely that it will be stuck. 3, hot car pouring cold water may also make the pump stuck normal operation, the oil pump is generally hot, this time should not make the oil pump encounter cold water, to avoid the pump head shell contraction lead to plunger stuck.
