Do you know the maintenance method of excavator accessories?


Maintenance method of excavator accessories

1. Use salt water as antifreeze
  wrong! Salt water does have a partial antifreeze function, but its fatal weakness is that it cannot prevent corrosion, rust, or cavitation. Professional Volvo excavator parts may even penetrate the cylinder and leak into the combustion chamber when it is considered serious.
2. The use of antifreeze in vehicles can save energy
  right! Because the specific heat of the aqueous solution of the ethylene glycol engine coolant is smaller than that of water, the time for the engine to reach a good working temperature is shorter than that of water, which is beneficial to the atomization of fuel and improves the thermal efficiency of the engine.
3. Add the same volume of water to the antifreeze, the freezing point of the antifreeze will double
  wrong! Antifreeze with a very low freezing point can indeed be mixed with water, but the freezing point will not increase proportionally with the amount of water added, such as the freezing point of -45.
After half of the antifreeze is mixed with water, the freezing point is only -17. about. The specific operation should be carried out according to the manufacturer's regulations.
4. Mixed use of different brands of antifreeze
  wrong! Each brand of antifreeze has its own unique balanced corrosion inhibition system. Once mixed, it may destroy the balance of the corrosion inhibition system and cause Volvo parts

5. The color of the antifreeze has changed, indicating that it has failed
  right! If the color changes, it means that the performance of antifreeze has changed greatly and should not be used again.
6. After adding antifreeze, it only takes a few minutes to start, and the antifreeze will change color, which proves that the quality of antifreeze is too poor.
  wrong! This is mainly caused by the corrosion pollution formed by the long-term cleaning of the water tank, which means that the water tank should be thoroughly cleaned with a special cleaning agent.
7. Use tap water to clean the windshield of the vehicle when driving in winter
  wrong! Tap water does not have an antifreeze function, nor can it effectively remove smudges and debris on the windshield. When the wiper wipes, the difficult-to-remove smudges attached to the glass may even scratch the glass. The correct way is to choose high-quality antifreeze glass water, and wipe the wiper gently to quickly solve the usual difficulties on the windshield.
For the removal of stains and stains, it gives you a clear vision.
8. Recklessly add brake fluid while driving
  wrong! The decrease of the brake fluid level is often caused by the leakage and damage of the hydraulic pipeline. When it is determined that it is normal consumption, it can be added. Otherwise, it may cause the brake failure.
