Automotive industry: Maintenance Knowledge
Car is now becoming increasingly popular, and is currently running on the road more and more cars. Taking a trip drove really convenient, but the car and the people, need to rest more work and maintenance. Following small car maintenance problems say about their experience.
Routine vehicle maintenance is very important. Only a slight effect on the daily maintenance of vehicles will cause unnecessary damage and endanger traffic safety. Such as the lack of oil will cause the pull cylinder Burnt, a part of the vehicle and other accidents cited dysfunction; Conversely, if done carefully daily work seriously, not only make the vehicle to keep it new, but to master the technical condition of the various parts of the vehicle, to avoid machinery accidents and traffic accidents
In fact, routine maintenance work is very simple, summed up: clean, tighten, check the supplement.
First, clean
Air contains a lot of dust, sand, and an acidic substance, not only the adhesion is easy to leak fuel, easily formed at a high temperature hard bake insulating layer, heat deterioration of mechanical properties and is easy to paint eroded electrostatic chuck body surface, making it premature fading.
A clean air filter
Steep dirty air filter will hinder fresh air into the cylinder, causing Aiki too thick, incomplete combustion, power down, exhaust exceeded. Now "air filter paper filter is generally used when cleaning Note: do not use water or oil wash, pat method should be used to wash and blow. Pat gently tapping the filter end face of the law that make the dust off. That law purged with compressed air filter out internal purge air pressure: force should not exceed 0.3N/Pa
2, clean oil filter
Confusion clogged oil filter, will hinder the flow of lubricating oil, poor engine lubrication, wear and even increase Burnt so on. To this end, should be regularly cleaned or replaced. Usually replaced once per driving 8000km, if the climate is dry. Should be shortened to 5 000km replaced once.
3, the cleaning battery
Generation of cars are generally maintenance-free batteries, first clean the top of the battery to avoid due to the electrolyte between the pole caused by a short circuit or other impurities; secondly clean the battery terminals to prevent the connector contacts do not produce oxides lead times are vent should be smooth, in order to avoid excessive pressure or temperature inside the battery leaving hands burst.
Second, tighten
Vehicles cleaned after each connection must be tightened. By the dry line vibration, bumps, swing and other reasons, will inevitably lead to loose connections, worn. Therefore, routine maintenance should be promptly tightened. Tightening connections daily work is directly related to traffic safety, especially important parts steering, braking, transmission, etc., must not be taken lightly.
1, first, the engine hose fittings around each tightening, anti-oil leakage.
2, followed by fastening each line and connector electrical equipment to prevent disconnection, short circuit, grounding, etc. affect the normal operation of electrical equipment.
3, again, the main connecting member fastened to check. If the generator drive belt, steering linkage machine a "junction point brakes, powertrain and tires.
Third, check the
After connecting fastening, Tony l should check the height and quality of the oil, due to fluid loss at high temperatures will gradually reduce surface oxidation and resulting poor performance
1, check the battery fluid level with a 5 N 6mm diameter tube, add liquid from the mouth to filter in contact with the vertical force, with the thumb of the closed upper end of the tube to live, lift tube, measuring the height of the liquid column is its Battery fluid level, the standard should be 10 N 15mm.
Height 2, check the oil level in the
Remove the dipstick cold car, after wiping, into the bottom of the oil pan, after observing its height should be between the upper and lower marking. Hot car should stall, stand all the oil flowing into the sump before measurement.
3, check the level of liquid coolant in the cold when the coolant tank shall be filled, the liquid level in the expansion tank should be between the markings. Hot car should be slightly higher than the standard liquid level
4, check the brake fluid, steering fluid level height
Unscrew the bolts, direct observation level is within the range specified marking.
5, check the oil quality
No matter what kind of oil, can use the following method to check. 1 1 l Exterior view of oil samples taken law, if more transparent, indicating that contamination is not serious; If mist, the oil in the seepage water; If you were, you may be lead or other abrasive contamination; If you were black, is being polluted exhaust gas temperature
Fluid samples will be taken out of the practice of 121 extended a drop on filter paper, if the proliferation of a wide area and the diffusion region and the oil droplets was no significant difference, indicating that the cleanliness of the oil well; otherwise it is clean of oil deteriorates.
Fourth, the supplement
1, oil supplement
If you did not find a significant deterioration of the oil, you should find leaks, check if there should be excluded, and promptly make up the same level of oil.
2, fluid replacement
If the oil deterioration or exceed the replacement cycle, should be replaced.
Usually every six months traveling 8000km or replaced once the oil; each driving 20,000 to 4 million meters or so to 2 years to replace a brake fluid; using coolant replaced every 1-2 years; every year or with the use of thousands of meters replaced once hydraulic oil.
In daily life we have to learn how to maintain their cars, so as to make their car for a long time to maintain good performance
