Cockpit water intake should be cleared in time After the rainy weather, people's mood will be better, but the performance of aerial vehicles may not be fully restored with the departure of the haze. Sometimes, heavy rain will also leave a lot of sequelae for high-altitude vehicles. The car manufacturer reminds the owners that after the rain, they should carefully check the car. Inspection items: engine compartment and cockpit Problem: Water spills into the cabin Rainwater can run through the hood into the engine compartment through the seams of the engine cover. Under normal conditions, the water will naturally drain away. However, sometimes leaves, dust and catkins will block the drainage holes, resulting in higher and higher water levels in the drainage system. At this time, water will leak into the cabin through the air intake. Therefore, after the rain, it is necessary to look at the position of the air intake hole in the separation part of the engine compartment and the cockpit of the aerial work platform and whether or not there is water accumulation in the grooves on both sides of the left and right fenders. If there is any accumulated water, you can take the clean water to flush the air intake. Hole, dredge the waterway, if still can not be solved, you need to clean the drainage system at the service station. Inspection item: air filter Problem: Odor in the car During the rainy season, the humidity is high, and some moisture will accumulate in the aerial vehicles. The hot air will cause mildew and odor in the air intake. Therefore, the air filter should be washed out to remove moisture and remove debris. There is an easy way to open the air conditioner's warm air to the maximum, and use a variety of outlet modes in turn, blowing about 15 minutes. At the time of air conditioning work, the outlet temperature can reach 40-50 degrees Celsius, so you can put the tide inside Hot air evaporates and removes mildew. Inspection item: Braking system Problem: Abnormal brake sound For disc brakes, brake discs tend to rust in the rain, causing abnormal brake sound. At this time, the owner of the aerial vehicle can start the vehicle, step on several brakes, and then stop. Whether the rust on the moving plate has been ground or not, if it has been cleaned, you can drive safely. If it is not ground, you can go to the service station for processing. However, this problem does not generally cause security risks. Sometimes there will be a situation where the lift truck feels astringent after starting and produces a feeling similar to that of the hand brake. This is because the brake shoe is sticking to the brake disc. Don't worry too much. Foot throttle, and then open for a while, you can hear a "click" sound, brake shoe and brake disc will be separated, then you can normal driving. Inspection item: headlight Question: The headlights are fogging The dust cover of high-altitude vehicles and the water entering the vehicle can easily cause rainwater to enter the lights. Water mist forms in the lampshade. The brightness of the lights will be affected when the lights enter the water. Corrosion of the circuit plugs may also cause the lights to erode. damage. After discovering the headlights entering the water, you can open the dust cover of the headlights and turn on the headlights. After 10 minutes of lighting the headlights, the mist in the headlights begins to disappear. After 1 hour, it can completely disappear. If it disappears, you do not need to worry. However, if there is water fog, we must go to a professional service station for processing. Inspection item: Hand brake cable Problem: Damage to the skin of the hand brake cable If the skin of the brake cable of the aerial workman is broken, it will cause the water to enter the cable, and the cable will be rusted. Therefore, if it is only slightly damaged, you can wrap the waterproof tape. If the damage is serious, you need to change the cable. . Inspection item: Body paint Problem: Decrease in vehicle surface gloss Because the rainwater contains impurities and acidic substances, after the high-altitude operation vehicle is wetted by rain, if the rain is not wiped off in time and then exposed to strong sunlight, the surface is prone to speckle and luster drop. Therefore, it is best to go after rain. The exterior of the aerial vehicle is cleaned. In addition, exhaust gas, dust, noise, and moisture will seep into the car body from the small hole in the chassis, causing the car body to rust and peel off, and the rubber in the protective layer will also age. Therefore, the chassis of the high-altitude truck should also be washed with clean water in time.
Boiler tubes is a one of seamless pipe. Manufacturing methods is the same as seamless tube, but it has the stringent requirements for manufacture of steel pipes. According to the temperature level,boiler tube is divided into general boiler tubes and high pressure boiler tube.

Production methods:
①general boiler tube temperature is below 350 ℃, using hot-rolled pipe or cold drawn tube manufacture Steel Pipe.
â‘¡ high-pressure boiler tube is used often in conditions of high temperature and high pressure pipe, the effect of high temperature flue gas and water vapor, oxidation and corrosion. Steel pipe with high rupture strength, high resistance to oxygen corrosion and have good organizational stability.
Boiler tubes purposes:
â‘ general boiler tubes is mainly used to manufacture water wall tubes, tubes in boiling water and super heated steam pipe, super heated steam locomotive boiler tubes, large and small smoke pipe and pipe arch brick.
â‘¡ high-pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, air guide tubes, main steam tubes, etc. for high-pressure and ultra-high-pressure boilers
Category:
General boiler tubes and high pressure boiler tube boiler tubes is exposed to high temperature performance. Boiler tubes in general, or high-pressure boiler tubes according to their use can be divided into a variety of steel pipe.
After the rain in summer, we must consult the high-altitude operation vehicle in time
Summer rain, rain should pay attention to inspection and maintenance of aerial platforms, if there is a problem aerial vehicles, aerial vehicle owners and maintenance personnel to repair consultation from the following aspects.
