the choice of hydraulic oil tank:
Oil tank in 315 tons hot pressingforming hydraulic pressThe hydraulic system is mainly used for oil storage, heat dissipation, separation of air contained in the oil and elimination of foam. When choosing a fuel tank, first consider the capacity, generally 315 tonsHot pressing hydraulic pressThe capacity of the oil tank is 3-4 times of the flow rate of the hydraulic pump. When all the hydraulic cylinders in the hydraulic system are extended, the oil tank cannot be lower than the small oil level, and the hydraulic cylinder cannot exceed the high oil level after returning.
Considering the structure of the hydraulic oil tank, the partition plate in the traditional oil tank cannot precipitate dirt. It is necessary to install a vertical partition plate along the longitudinal axis and leave a space between the partition plate and the end plate of the hydraulic oil tank so that both sides of the partition plate can be connected. The inlet and outlet of the hydraulic pump oil of the 315-ton hot press forming hydraulic press are arranged on the side of the non-connected partition plate so that the distance between the oil inlet oil and the oil return oil can be kept as far as far as possible, thus convenient for heat dissipation.
the choice of oil filter:
Usually, the polluted particles with a diameter of less than 10 μm have little effect on the hydraulic pump. If it exceeds 10 μm, especially when it exceeds 40 μm, it will seriously affect the service life of the hydraulic pump of the 315-ton hot pressing hydraulic press. The solid particles in the hydraulic oil will make the relative movement parts in the pump wear quickly, so it is necessary to install an oil filter to improve the pollution problem.
Selection of oil cooler:
The working oil temperature of the hydraulic system of the 315 ton hot press forming hydraulic press is generally 15-80 ℃, and the ideal temperature is 25~55 ℃. When the hydraulic system is running, there will be mechanical loss, pressure loss and volume loss. These losses are inevitable when a machine is working. All these losses will become heat, a small part of the heat will evaporate to the outside world, and most of the heat will accumulate in the fuel tank. When the temperature of the fuel tank rises. However, if the oil temperature is too high, the hydraulic oil will deteriorate rapidly, reduce the viscosity and lubricity of the oil, lead to the leakage problem of the 315-ton hot pressing hydraulic press and the wear of the parts, and reduce the service life. Therefore, it is necessary to install the oil cooler.
