Due to the mobile characteristics of construction machinery, the design of its hydraulic tank is different from that of an ordinary hydraulic tank. The following introduces several issues that should be paid attention to in the design of the mobile construction machinery hydraulic tank:
1. It should be considered that the lowest and highest oil level of construction machinery climbing needs to be met at the same time in the uphill and downhill, your oil suction filter can not be exposed, and the end cover of the oil filter and air filter can not be all in the oil;
2. Balance of weight to maintain the proper center of gravity of the vehicle;
3. Good heat dissipation to ensure that the oil temperature is not too high, so it is necessary to consider the installation position and the ventilation channel design of the vehicle;
4. To consider the working conditions, to prevent oil leakage or the entry of dirt things in the harsh external environment, more stringent than the ordinary system requirements;
5. Fully consider the layout, the shape is not necessarily regular, and the adjacent parts should be coordinated;
6. Anti-rust treatment of the inner wall is generally adopted by pickling phosphating.
7. The design and calculation of the tank volume, to better precipitate impurities and separate air, the effective volume of the tank (the tank volume of the liquid level only accounts for 80% of the tank height) is generally taken as 2-7 times the volume of the oil discharged by the hydraulic pump per minute. When the system is a low-pressure system, take 2-4 times; When the system is medium and high pressure, take 5-7 times; The walking machine is generally taken 2 times. You have to make sure you have enough oil.
