The working aerial vehicles suddenly stopped inexplicably, and after a while, they could start normal operations again, but then they turned off again. Why is such an intermittent flameout in the end? The intermittent flameout of the engine of the aerial vehicle can be summarized as the following reasons:

1. It is necessary to carefully check whether the spark plugs of the high-altitude truck and the operation of the engine and the fuel pump, the air nozzle of each cylinder, and the fuel pump circuit are all normal. In addition, the interval between the intake air and the exhaust valve must be checked. Whether the pressure value of the cylinder, the presence of air intake manifold leaks, the operation of the fuel vapor control solenoid valve, the operation of the EGR valve cylinder, etc., are all within the range of production. Whether the relevant line connector of the electric control fuel injection system of the aerial vehicle has loosened or the like.

2. In order to check the hydraulic pressure value of the entire vehicle under the aerial working platform, the system pressure value cannot exceed 16 Mpa.

3. The idle speed of the engine of the aerial vehicle is not stable, or the idling speed is too low. It is necessary to adjust the screws of the engine idle speed blackly, or to adjust the idle speed through the throttle cable.

4. When the aerial working platform is under work, if the engine building fails to start normally, it cannot be started. Because the legs of the vehicle are all supported on the ground, there is no way to move and the service station can be immediately looked for. Personnel go to the job site to carry out repairs. If not, they can only use the starter as an emergency pump. If the driver does not step on the clutch, the driver will be forced to take the vehicle back to the vehicle. Use a trailer to pull the aerial vehicle to the repair station for maintenance.

Flake Graphite

Flake Graphite is a natural crystalline graphite. It is shaped like fish phosphorus, and is a six-square crystal system. It is layered and has good properties of high temperature resistance, conduction, heat conduction, lubrication, plasticization and acid and alkali resistance.

Flake graphite is a natural solid lubricant of layered structure, rich in resources and cheap in price.

feature

The flake graphite crystallization is complete, the film is thin and the toughness is good, the materialized performance is excellent, has the good thermal conductivity, the conductivity, the thermal shock resistance, corrosion resistance and so on.

distribution

In December 2015, geological prospectors found a large scale graphite mine in alashan, Inner Mongolia. The total amount of graphite resources was 1. 300 million tons, about 7 of the world's recoverable reserves. 3%, average grade 5. 45%. According to the introduction, such high grade, large-scale graphite mineral deposits are rare in China. [1]

In 2013, the U.S. geological survey reported that the global scale of graphite minerals was less than 5 million tons. The discovery was made in alashan, which has a large scale of 703 million tons of graphite in the area of zahan mushi.

refractory

Flake graphite is widely used in the treatment of gold industry of advanced refractory materials and coatings. Such as magnesia carbon brick, crucible, etc. Military industrial firework material stabilizer, smelting industrial desulfurization growth agent, light industry lead pen, electric industry carbon brush, battery industry electrode, fertilizer industry catalyst and so on. The flake graphite is deeply processed, and it can produce the graphite milk for lubricant, deformable agent, drawing agent, conductive coating and so on. It can also produce expanded graphite for flexible graphite products such as flexible graphite seals and flexible graphite composite products.

dope

The flake graphite as the functional filler of coating is mainly used for anticorrosive coating, fire retardant coating and conductive coating.

As an anticorrosive material, it has anti-rust primer, such as carbon black, talcum powder and oil, which has good corrosion resistance of chemicals and solvents. If you add zinc and yellow to the formula, it is better to rust.

A graphite interlayer compound obtained from Natural Graphite scales as raw materials, chemically or electrochemically treated. Expandable graphite under the condition of heat, swelling volume (up to 300 times) suffocate the flames, at the same time generate inflation, to isolate the flame, delay or interrupt the effect of flame spread, and itself does not burn, good flexibility, high surface energy, intensity of carbonized layer. But the volume and dosage of the expansive body should be suitable. The test shows that the 150um particles, 30% expansion multiples and 5% dosage are the most suitable.

The flake graphite can be directly used as a carbon conductive filler and can be made into a composite conductive filler for conductive coatings. However, due to the large addition of graphite flake, the coating can be brittle and its application is limited. Therefore, measures are taken to further improve the conductivity of graphite and effectively reduce the amount of graphite flake. Our domestic chemical machinery research institute has developed a high temperature and corrosion resistant resin as basic material, with the strong ability of conducting electrostatic entities large flake graphite flake as the main aggregates, with high intensity of ontology Good abrasion resistance.

The anti - deformation cracking - good short - cut fiber material is a solvent - free thick film conductive coating. The coating has the characteristics of anti-corrosive media penetration, small residual stress, good anti-matrix deformation, stable construction performance and long - term conductive static. Can be used in oil tank inner wall guide electrostatic coating. With electroless plating technique, according to the data of graphite powders metallized, such as copper, nickel, silver, such as the preparation of composite conductive filler, with 30% of the amount used in conductive coating, not only its conductivity is very good, and further improve corrosion.
