The reasons for the oil leakage problem of the hydraulic baler
can be started from the following aspects. The absolute pressure of the liquid in the hydraulic baler oil tank must be equal to or greater than the atmospheric pressure. This is the external condition that the hydraulic pump of the hydraulic baler
can absorb the oil. Therefore, in order to ensure the normal oil absorption of the hydraulic pump of the hydraulic baler
, the oil tank must be connected to the atmosphere, or a closed gram pressure oil tank must be used.
1. The system pressure is adjusted too high, causing the seal or the sealing surface to leak. Appropriately reduce the pressure of the hydraulic system of the straw baler
, but still adjust the pressure of the hydraulic system to the specified range according to the requirements of the machine manual, and do not adjust it too high.
2. There is leakage in the valve. The reason is that the spool valve of the straw baler increases the gap. At this time, the body hole of the valve should be ground, and the gap should be matched according to the actual size of the valve body hole.
3. Seal leakage. The damage and aging of the seals of the hydraulic baler make the seal poor. At this time, these broken seals should be replaced in time. When the directional seals are installed in the wrong direction, they should be reinstalled.
