Analysis of the reasons for the blockage of the fuel circuit of the truck-mounted crane Tow Crane

During the daily usage of the automobilinis kranas, ypač žiemą, gali atsirasti scenarijų, tokių kaip sunkus paleidimas arba netikėtas užstrigimas transportavimo metu, Tai kebli padėtis, su kuria transporto priemonių savininkai susiduria labai nenoriai. Iš esmės, the primary culprit behind these circumstances is the obstruction within the fuel circuit of the automobilinis kranas. When confronted with a fuel circuit malfunction of the automobilinis kranas, it is advisable to initially undertake a visual examination of the components and pipelines within the fuel system, followed by separate inspections of the low-pressure and high-pressure fuel circuits of the automobilinis kranas.

We are aware that the fuel supply system of the automobilinis kranas can be bifurcated into two segments: the low-pressure fuel circuit and the high-pressure fuel circuit. Generally speaking, the cylinders within the high-pressure fuel circuit operate independently of one another, and faults typically manifest in individual cylinders. Ir atvirkščiai, the low-pressure fuel circuit constitutes a shared oil passage. Once a malfunction emerges in this circuit, the entire machinery often grinds to a halt.

Dabar, let’s delve deeper into the common causes behind the blockage of the fuel circuit of the truck-mounted crane:

The tubing of the automobilinis kranas may sustain impacts or collisions, or the filter screen at the pipeline joint, if not cleaned after prolonged usage, can accumulate debris and subsequently obstruct the fuel circuit. Small particles, dirt, or rust can gradually accumulate on the filter screen, restricting the smooth flow of fuel. Even minor dents or bends in the tubing can impede the fuel’s passage, leading to reduced fuel supply or complete blockage over time.
Žiemą, if the sewage within the fuel-water separator of the automobilinis kranas is not promptly evacuated and the temperature dips below 0°C, the water can freeze within the fuel-water separator. This frozen water effectively blocks the fuel circuit. The accumulation of water in the separator, when not dealt with in a timely manner, can transform into ice, creating a physical barrier that hinders the fuel from flowing through, thereby disrupting the normal fuel supply to the engine.
The elevated temperature generated by the engine of the automobilinis kranas can heat the adjacent diesel pipeline. This heat can vaporize the diesel within, giving rise to symptoms similar to air intake within the aforementioned pipeline and subsequently interrupting the fuel supply. The vaporization of diesel due to excessive heat can cause inconsistent fuel pressure and flow, resulting in unstable engine performance or even stalling.
The filter core of the diesel filter of the automobilinis kranas can accumulate dirt over time. Failure to replace it promptly or conduct regular and thorough cleaning can lead to its clogging by impurities present in the fuel. This obstruction within the filter core impedes the fuel circuit and prevents the smooth supply of fuel. Even minute contaminants can gradually build up and restrict the passage of fuel, affecting the engine’s fuel intake and overall performance.
There are valves installed on the fuel tank cover of the automobilinis kranas. In the event of a blockage, as the fuel transfer pump continuously extracts fuel, a vacuum can be formed within the fuel tank. This vacuum makes it impossible for the fuel to be drawn out. A clogged valve disrupts the pressure balance within the tank, preventing the normal suction of fuel and causing a disruption in the fuel supply chain.

Upon familiarizing ourselves with the causes of fuel circuit blockage, conducting sequential maintenance and inspections can effectively curtail the incidence of faults during the operation of the automobilinis kranas and significantly alleviate the burden on the driver.

Pavyzdžiui, regularly inspecting the tubing for any signs of damage or deformation and cleaning or replacing the pipeline joint filter screens at prescribed intervals can preempt potential blockages. Panašiai, ensuring the timely drainage of the fuel-water separator, especially in cold weather conditions, and maintaining a clean and functional diesel filter core can go a long way in preventing fuel supply disruptions.

Apibendrinant, a comprehensive understanding of the causes of fuel circuit blockages and the implementation of proactive maintenance and inspection strategies are indispensable for ensuring the seamless and reliable operation of the automobilinis kranas. This not only enhances the vehicle’s performance and longevity but also provides a safer and more efficient working environment for the driver.
