Truck usage entails speedy wear and tear and if they are not regularly maintained a lot of accidents can occur. Maintenance and work on trucks is not something that can be trusted onto anyone. It is essential that a truck’s work is done with responsibility and only by an expert. Here are 5 things that every good truck mechanic adelaide should know about truck repair.

Serpentine belts

The serpentine belt drives multiple peripheral devices such as the power steering pump, water pump, alternator, compressor, air pump and air conditioner. If a truck starts to squeal then it is an indication that this belt needs to be checked, fixed or changed. Do not compromise and change the belt if it is chipped, torn or cracked. Problems with serpentine belts can manifest through a heated engine, power steering and AC not functioning. A trucks complete breakdown also indicates failure in terms of this belt.

Suspension and shocks

Due to constant wear and tear through heavy lifting shocks of a truck are bound to trouble. This calls for suspension repair. Bad suspensions entails that the truck will be out of control specifically while turning and stopping. If a truck driver isn’t able to control his truck imagine the damage that can take place on the road. Further, if uneven wearing down and balding spots are noticeable on the tire then this means that suspension needs attention. Take a look at the shocks under the truck. If they are greasy and oily then this denotes leaking and a need for repairing.

Working with a diesel engine

Heavy vehicles such as trucks are mostly diesel based. Therefore a good truck repair mechanic must know how to specifically deal with an engine that works on diesel. This is where the difference and specialization in terms of trucks lie. A good knowledge about the relationship between the engine and diesel will help in running diagnosis and repairing. Engine valves should be adjusted at least yearly as this will help in estimating the work required on the criteria of mileage. Diesel particulate filters require a replacement often to remove ash left over from regeneration. Inadequate diesel exhaust fluid can indicate fault codes and reduced engine performance.

Filters

Fuel filters should be replaced timely so that deposits do not reach and damage the engine. Any cases of engine damage ranging from reduced performance to no performance must include replacement of fuel filters. Inlet piping and hoses should be checked for deterioration. Air filters should also be changed as they too restrict the performance of the engine if they are clogged. Every oil change should be followed by an oil filter change.

Radiator

Diesel engines produce a lot of heat which can do a lot of damage by overheating if a radiator is not doing its job properly. Coolant must be checked and definitely replaced at least every two years or as need be. Complete coolant maintenance includes radiator cleaning, coolant testing, checking coolant freeze temperature and the potency of the chemical components.

In our country the ANEV is the association of environmental protection (recognized pursuant to Law no. 349 of 8 July 1986) established in July 2002 which brings together around 70 companies operating in the wind sector.

ANEV is a member of Confindustria Energia and is the Italian Association present on the Management Board of the corresponding European and World associations such as WWEA – GWEC – EWEA as well as joining UNI – CEI-AIEE. Among the aims of the Association is to contribute to the promotion and use of the wind source in a balanced relationship between settlements and nature , as well as to promote research and technological development aimed at the use of the wind resource and the rational use of energy, as well as the dissemination of correct information based on real data.

Wind energy represented 51% of the new installed capacity in 2016 in Europe , connecting a total of 12.5 GW to the network , distributed among the 28 EU Member States, of which 10,923 MW on-shore and 1,567 MW off- shore.

The total installed wind capacity in Europe today stands at 153.7 GW. Wind energy covered 10.4% of electricity needs last year. Germany has installed the largest share of new wind energy, or 44% of the EU total. Five member states reached the record year: France, the Netherlands, Finland, Ireland and Lithuania. All the Renewables together have added 86% of new installed power in 2016 – 21.1 GW out of 24.5 GW. In Italy only 282.5 MW installed, equal to an investment flow of over 350 million euros.

Investments in new on-shore and off-shore wind farms reached a record € 27.5 billion. The offshore wind has increased by 39% every year to reach 18.2 billion euros, while for on-shore investments have decreased by 29% reaching 9.3 billion euros.

Wind energy in the world and in the future
In 2010 more than half of all new wind power was installed outside the traditional European and North American markets. This is linked in particular to the strong growth of installations in China that represented almost half of the new wind plants (16.5 GW).

The figures provided by the Global Wind Energy Council (GWEC) show that in 2007 there was an increase in installed power of 20 GW, bringing the total installed wind power capacity to 94 GW, compared to 74 GW in 2006. Despite the constraints faced by the wind turbine production industries, the annual market continued to grow at an estimated rate of 37% , after a 32% growth in 2006. In terms of economic value, the wind sector has become one of the main players of energy markets, with a total value of new equipment installed in 2007 of 36 billion dollars.

Wind energy is one of the energy sources exploited since the ancient times . It is in itself the kinetic energy of the wind and its conversion into mechanical or electrical energy. Surely the most ancient application is the nautical one, through the use of the sail, the one in the windmills, and today instead the wind energy is exploited for the electric production.

Wind energy is the kinetic energy produced by the moving air and usually called wind . Wind is the movement of air on the earth’s surface, between areas of high pressure and low pressure.

depending on factors such as the angle of incidence of its rays on the surface (which differs with the latitude and time of day) and of the soil (light or dark soil, rock, sand, thick vegetation, water).

Temperature differences therefore generate pressure differences. The presence of two points with different atmospheric pressure originates a force, called “force of the pressure gradient”, which acts by pressing on an air mass to try to re-establish the balance and therefore giving rise to the wind phenomenon. Furthermore, the rotation of the Earth drags the atmosphere around it causing movement of large air masses (Coriolis Force). These effects naturally combine with each other, leading to the natural variability of the winds.

Hardly a wind turbine is “only”: therefore we often refer to “wind farms” when dozens (sometimes hundreds) of generators are concentrated in an area favorable to the production of energy.

There are on-shore, near-shore and off-shore wind farms.
Onshore wind farms refer to parks at least 10 km from the sea, usually in large plains (such as those in the central area of ​​the United States) favorable to constant and substantial wind currents).

The near-shore wind includes all the facilities on the coast, up to 10 km away. It is characterized by the attempt to exploit the winds that come from the sea and strike the coast with constancy throughout the year and have sufficient speed.

As far as off-shore wind is concerned, these are usually more stable plants, which provide more energy (since the speed and constancy of the wind away from the coast provide better conditions for the conversion of energy) and have a lower visual impact, however the construction and maintenance costs are significantly higher.

There are also smaller plants like small on-shore wind power plants , which can supply electricity to isolated places; or small domestic wind turbines that are in development and some already on the market, which can be installed on the roof or sometimes even on the balcony, and which can also produce excess energy that can be purchased by electricity companies.
