How can a fire engine be used longer?
Fire trucks need frequent maintenance to keep the car in normal condition. The average driver is often very big about the maintenance, because he knows that the car will be opened soon without maintenance, but he is also very sad to pay for the maintenance. Under normal circumstances, oil is changed every 10,000 kilometers or once a year, brake oil is changed every two years, and gear oil needs to be replaced longer. In addition to these three kinds of oils have a relatively fixed maintenance mileage, what other clutch oil, power steering oil, water tanks, etc. are replenished or replaced as appropriate.
The purpose of maintenance is inspection, and the purpose of inspection is prevention. In addition to the liquids mentioned above, there are some solid things in the car that need to be replaced. The most common ones are spark plugs and air filters. In general, platinum spark plugs are replaced once every 100,000 kilometers, and air filters are usually replaced by 40,000 kilometers. Then there is the timing belt and its idler gear set. Only the vehicles with timing belts need to be replaced. The engines with the timing chain design may not be replaced when they are used for scrap. The replacement of the timing belt is the most expensive one in normal maintenance, and it must not be saved. In fact, so few things need to be replaced, because the real purpose of maintenance is not to replace these consumables, but to check whether the vehicle is abnormal.
Many people have a misconception that maintenance is an oil change. However, in fact, replacing oil has never been the focus of maintenance, at most, it is nothing more than routine business. The main purpose of maintenance is to check if there are any damage or need to be adjusted on the parts of the vehicle. The actions during these inspections will ensure the safety of your driving. There are many inspection items, which are generally part of the inspection engine, the exterior of the car body, and the chassis. Open the hood to check the water tank, oil, gearbox, hydraulic steering wheel hydraulic oil, brake oil, wiper water, batteries, belts, air filters, etc., then check the wipers, wiper flusher head, the whole car lights, and then Check the brakes and hand brakes, tires, drive shafts, shock absorbers, and various oil seal cushion rubber pads, and pay attention to abnormal oil and various abnormal phenomena in the bottom of the vehicle.
Oil and oil filters are something that must be changed every time. Before changing the oil, you should first take out the oil scale and check whether the oil is consumed and whether the viscosity is normal or not. In addition to paying attention to the normal amount of water, the tank water should also pay attention to whether the water color is normal. When the tank water is abnormally dirty, the tank water must be completely renewed. Transmission oil is generally the same as checking the amount of oil and color, power steering oil. In addition to changing the brake oil every two years, each time the maintenance must check the amount of oil and color, when the height drops a little when it is not anxious to add, it is because of the brake pads caused by the wear and tear caused by the brake pump, replaced with new To make the amount of oil will rise.
There are two kinds of batteries for fire engines, one is water-free, and the other is traditional water. The water-free type usually depends on the check mark. The traditional water-filled type battery must be filled with pure water to the full water level. Check the battery is usually used to check the battery checker, when the battery voltage drop is too much, on behalf of the battery aging need to be replaced, the battery life is usually two years. The air cleaner core is generally a one-for-one 40,000-kilometer change, but it will be checked every time it is repaired to avoid damage. The last thing to check is the exhaust pollution. Usually this is off and it means no problem with the engine.
Chassis inspection is usually the most difficult to do, because there is no top car machine, brake force testing machine and other equipment. The most important brake inspection is the brake force. Generally, the vehicle should be more than 80% of the vehicle weight. The second is to check the film thickness so that the film thickness is less than 2mm and it needs to be replaced immediately. The tires are to be checked for tire pressure, wear, eating and aging. Tire pattern 1.6mm will be replaced immediately. When you eat the tire, you must check the position. The tire aging also needs to be replaced. Even if the tread pattern is very deep, the tire will lose its elasticity and grip due to aging under ultraviolet light. Usually, the tire is not recommended for use. More than 4 years. Then there is the inspection of the transmission and suspension system at the bottom of the vehicle. Basically it is to check whether there is any damage to the oil seal or whether there is any abnormal oil leakage.
maintenance:
After a summer of use, many owners will find that the interior of the car seems to have a taste of mildew. In fact, this situation is mainly due to the fact that the water in the evaporation box cannot be volatilized for a long time, resulting in the growth of bacteria. The way to avoid this problem is simple:
First, when the weather is not hot, the windows on both sides of the vehicle will be shaken and the windows of the vehicles will be ventilated to keep the air in the vehicle fresh.
Second, when the normal air conditioning is running, the refrigeration pump can be turned off before reaching the destination, but the air supply function is kept on, so that the natural wind will dry the water in the evaporation box.
Third, because there is more rain in the summer, cars will often run on some wading roads, which will cause a lot of silt on the lower part of the air-conditioning condenser, which will cause corrosion of the condenser for a long time, thus shortening the service life of air conditioners. It is worth noting that, when cleaning, be careful not to knock down the condenser heat sink, nor can it damage the tube.
Clean and replace the air conditioner filter in time:
The quality of good air conditioning depends mainly on the air conditioning filter, so it is often cleaned and replaced regularly. It is understood that under normal circumstances, every 5,000 km or 3 months to clean the air conditioning filter every 20,000 km or 12 months replacement air conditioning filter. The air-conditioning filter is a filter for the air intake of the air conditioner in the car. If it is not cleaned for a long time, the dust attached to it will blow into the car as the air conditioner is turned on.
Therefore, in the summer and autumn, the air conditioner filter should be cleaned and replaced in time. The replacement procedure is very simple, as long as the filter is taken out, high pressure water gun and sterilizer can be sprayed.
Air-conditioning piping clean and unobstructed:
The cleaning of air-conditioning pipelines is a very important task because of the dry weather in autumn and the frequent use of air-conditioning in the summer. Some dirt, dust, and bacteria will grow and accumulate in air-conditioning ducts. If it is not cleaned up in time, it will lead to poor cooling effect, small air output, and even air conditioning system failure.
Under normal circumstances, special air-conditioning cleaning agent can be used to clean the air-conditioning pipeline. After the vehicle is started, the air-conditioning air inlet is opened, the air volume is maximized and the temperature is adjusted to the minimum; the air-conditioning cleaning agent is injected into the internal pipeline from the air inlet; After about 20 minutes, dirt from the air-conditioning pipeline can be discharged from the sewage pipe.
