Everyone knows that tankers belong to dangerous goods carriers. Therefore, we must always pay attention to the performance of the vehicles and avoid causing danger to ourselves and the surrounding areas. So how do you pay attention? The word maintenance, then the question, from where to start it? Filter element. The filter element plays a role in filtration and is the center of vehicle maintenance. If it is not maintained on time, it will affect the performance of the vehicle. The filter cartridges used in tanker trucks include engine filters, air filters, and air-conditioning filters. Let's take a look at the maintenance tips for the tank filter cartridges. First, the engine filter Tanker engine filter filter media in the engine lubrication system, can be replaced according to their mileage, the best state is every 3000 kilometers should be replaced once, the external steam filter is replaced every 5000 kilometers, the oil pump is one for every 4000 Kilometers are replaced once. When the oil pump fails, it is best to replace them together. Second, the air filter The air filter filters the medium in the engine air intake system. The replacement cycle is generally changed every 2000 km. Of course, different manufacturers will have different standards. If your frequency of cleaning is not high or even not clear, you must replace it according to the replacement cycle. If you clean it regularly, you can extend the replacement cycle appropriately. It is possible to replace it every 3,000 kilometers or 5,000 kilometers. Third, air conditioning filter In fact, air-conditioning filter cartridges need to be renewed every year. Otherwise, they will produce odors in the summer, and even worse, they will breed bacteria and affect health. It is therefore necessary to replace the air filter. The air-conditioning filter is just like the mask we wear. It is the first line of defense for fresh air. It is best to clean it every quarter to ensure that you can breathe fresh air all the time. In addition, attention should be paid to the replacement of spark plugs. The replacement cycle time for nickel alloys is 2,000 kilometers for ordinary copper cores, 4000 kilometers for platinum spark plugs, and 7,000 kilometers for sheet metal spark plugs. Have you learned about car tank filter maintenance owners? Take a look at your mileage, and check the filters for new ones.
The domestic current
situation of the die-casting mould
Die Casting Mould industry
has developed rapidly in our country, the total output growth significantly,
domestic die casting mold production after the United States, has become the
second in the world, become the veritable die-casting superpower. It can have
such achievement because of our country with unique broad market advantages and
relatively cheap labor force. Depend on very obvious price in the international
trade market, we produced the die casting mould which occupies a bigger
superiority, according to the situation, in the future Chinese die casting
industry development prospects are very broad.

What is the Moldflow analysis, this conception
derived fromtaiwan.
it's a precess through the computer for injection molding simulation by data
simulate software, and get data result. Then assess the feasibilty of the mold
program through these results to perfect mold and production designation.The
common software for plastic mold such as moldflow, moldex 3D and so on. And the
common software for Aluminum Die Casting Parts such as PROCAST, FLOW 3D and so
on.
