Dilute one filling station control system
Harvester dilute the original oil pump station is by detecting the pressure to control their working condition. Petrol filling stations equipped with three pressure gauges, oil pressure, respectively, after filtration pressure, oil pressure. Oil pressure detected by the electric contact pressure gauge, the general control in between 0.2 ~ 0.4MPa. When the oil pressure is lower than 0.2MPa at the same time when the oil pump 2; oil pressure greater than 0.4MPa stop 1 pumps, oil pumps from 1. As the flow of petrol filling stations the size of a direct reflection of working conditions. Pressure can only indirectly reflect the flow of change, and the pressure increases the flow does not necessarily increase, so the control flow is the most direct and effective. Especially in the winter time due to downtime and operation of large temperature changes, each time at startup harvesters should adjust the pressure valve so that oil to reach 0.2 ~ 0.4MPa, but as the running time for the growth temperature is also growing lubricants, viscosity declining, with the attendant pressure to reduce.
