With the development of the market, more and more second-hand cars are trusted by people, and the daily transaction volume is also growing. Due to the different conditions of used cars, friends who bought used cars do not know how to maintain them, and look at the cars they bought. I do not know where to start, let us next discuss how to carry out maintenance after buying a used car?
First: Change oil and machine filter. After buying a used car, you must first replace the "liquid", such as oil, brake oil, water tank coolant and so on. Change the machine oil at the same time to ensure that the oil path is not blocked by impurities.
Second: change transmission oil. Transmission oil is the most easily overlooked. After purchasing a used car, it should replace the transmission oil that meets the manufacturer's regulations. This is particularly important for vehicles over five years old. In the case of a rear-wheel drive, the gear oil must be replaced.
Third: change the engine timing belt and water pump. For vehicles with a vehicle age of more than five years or a mileage of more than 70,000 kilometers, the safest method is to replace the new engine timing belt with a new one. Water pump and its belt.
Fourth: Check the tires. If the tires have been worn away, new tires should be replaced. Some vehicles may have been replaced with tires for three to four years. Although the tires may appear clean or have deep pits, the gums may already harden and provide insufficient grip.
Fifth: steam cleaning compartment. In addition to the common vacuum cleaning and deep cleaning of steam, steps such as disinfection and negative ion air purification are also required. All kinds of odors can be eliminated.
Sixth: Check spark plugs. The platinum or Iridium metal spark plugs currently used in automobiles do not need to be replaced too frequently. Normally 30,000 kilometers or more need to be replaced. You can first remove the fire nozzle and check if you need to replace it.
Seventh: Check the battery. Checking the date of the battery, or the status of the display, if the sound is weak or the lighting is dim when the engine is started, it is a sign of battery exhaustion and it is best to replace it as soon as possible.
Although the inspections of the above steps were carried out, it is not all that matters. We must pay constant attention to changes in the car.
The multifunctional hammer mill is widely used in crushing various biomass wood waste and straw material. The motor and the hammers are directly connected by the coupling. There is no dead angle during the crushing so the finished product is very fine. The corners of the hammers are welded with high hardness material like carbon tungsten alloy. The welding layer thickness is around 3mm. The lifetime is 7- 8 times by normal 65Mn overall quenching hammer. The rotor has made the balance test and can work backward. It`s the best choice to prepare milled material for pellet machine.
