We know that the bulk cement trucks are equipped with air compressor, air compressor domestic air compressor using a pendulum, and foreign companies with bulk cement truck screw or Roots-type. At this time, some people may ask why the bulk cement trucks in China are all equipped with pendulum air compressors. However, foreign countries use screw type or Roots type. What's the difference? Next, bulk cement truck manufacturers talk about the reasons for them. The difference between domestic and foreign air compressors is mainly due to price and philosophy. Foreign car screw is light in weight and quick to discharge. It is the same car. It can be installed in foreign countries. At the same time, you can run a few more times. In addition, the lifespan of the in-vehicle screw is usually very long, coupled with a good car, good cans. Those bulk cement trucks have no problem running for 10 years. The disadvantages are: The price is a short board, which is generally 7-8 times that of the domestic pendulum, and the price is too expensive. However, in China, bulk cement trucks are heavily overloaded, and air compressors are generally scrapped after being used for 2 to 3 years. The failure rate of domestic pendulum bar machines is high and the service life is not yet long, but China’s national conditions are the same. The lifespan of foreign imported car air compressors is 5 times that of cars. In fact, in terms of comprehensive loading and unloading efficiency, the use of foreign vehicle-mounted screw machines is higher than domestically produced pendulums. The initial investment is high, and the recovery of investment is also fast.
