Dry Powder Fire Truck Is A Standing Fire Engine For Petrochemical Companies
- Nov 03, 2017 -

The main equipment of dry powder fire extinguishing agent and dry powder injection equipment, firefighting pumps and fire equipment, etc., mainly using dry powder to save combustible and flammable liquids. Flammable gas fire, live equipment fire, can also extinguish the general material fire. For large-scale chemical plant pipeline fire, the effect of extinguishing is particularly significant. It is a standing fire engine for petrochemical enterprises.

Dry-powder fire engines need regular maintenance to keep the condition normal. General drivers often on the maintenance of this matter is very big, because clearly know that the car is not maintained soon, but also very heartache for maintenance and pay the money. In general, the oil every 10,000 kilometers or a year to change the same, brake oil every two years, and gear oil needs to be replaced longer. In addition to these 3 kinds of oil has a relatively fixed mileage, other what clutch oil, power direction oil, water tanks, etc. are supplemented or replaced as appropriate. The purpose of maintenance is checked, and the purpose of inspection is prevented. In addition to the above-mentioned liquids, there are some solid things to change, most often the spark plugs and air filters. Generally platinum spark plugs about 100,000 km change once, and the air filter is generally 40,000 km replacement once. Then the timing belt and its idler wheel group, only the use of the timing belt of the vehicle need to be replaced, the use of the timing chain design engine probably used to scrap does not need to be replaced. And the replacement of the belt is the normal maintenance of the most expensive one, but also tens of millions of provinces must not. In fact, the need to replace the things so little, because the real purpose of maintenance is not to replace these supplies, but to check the vehicle has the same shape.

Many people have a misconception that maintenance is changing oil. In fact, changing oil is never the focus of maintenance. The main purpose of maintenance is to check, check the car parts are not damaged or need to be adjusted, these checks will be able to protect your driving safety. There are a lot of items to check, mostly the parts of the engine, the exterior of the body and the chassis. Open the hood to check the tank, oil, variable-speed tank, power steering wheel hydraulic oil, brake oil, wiper water, battery, belt, air filter and so on, next to check the wiper, wiper nozzle, the whole car lights, and then to check the brakes and hand brakes, tires, transmission shafts, shock absorbers, a variety of oil seals cushion rubber Cushion, and pay attention to the car at the bottom of the abnormal oil and all kinds of abnormal phenomenon.

Oil and oil filters are things that must be exchanged for each maintenance. Before changing the oil, should take out the oil volume ruler first, check whether the oil consumption and viscosity of normal or not can be released after the oil. Water tanks In addition to pay attention to the normal volume, but also pay attention to the normal color. When the water tank is unusually dirty, the water tank must be completely recycled. Gearbox oil generally check the amount of oil and color, power steering wheel oil is the same. Brake oil In addition to every two years, every maintenance to check the amount of oil and color, when the height of the drop is not with a little rush to add, it is because to make the piece of wear and tear caused by the pump, put on new to make the amount of oil will rebound.

There are two kinds of batteries for fire engines, one is water-free, the other is traditional water-adding. The water-free type usually depends on the check mark, and the traditional water-type battery should be added to the full level. Check the battery usually with the battery check machine to check, when the battery pressure drop too much, on behalf of the battery aging needs to be replaced, the battery life is usually two years. air filter core is generally 40,000 kilometers a change, but every maintenance will be checked to avoid breakage and do not know. Finally check the exhaust pollution situation, usually this is off the representative engine no problem.

The chassis inspection is usually the most difficult to do, because there is no car jacking machine, brake strength tester and other equipment. The most important thing about braking is the braking strength, which should be more than 80% of the vehicle weight. Second is to check to make the thickness of the film to make the thickness of less than 2mm will be replaced immediately. Tires to check tire pressure, wear, eating tires and aging conditions. Tread pattern 1.6mm must be replaced immediately, eat the fetus to check positioning, tire aging also need to be replaced, even if the tread is very deep or the same, because the tires will be exposed to ultraviolet radiation aging loss of elasticity and grip, it is generally recommended that the use of tires not more than 4 years. Another is to check the car bottom of the transmission and suspension system, basically is to check whether oil seal damage, there is no abnormal oil leakage phenomenon.
