The hydraulic system of hydraulic oil press is very important
The invention has the advantages of simple operation, fast oil transmission, clean oil and convenient maintenance, and is favored by consumers. The hydraulic system of hydraulic press is the heart of hydraulic press. The following describes the maintenance of hydraulic press hydraulic system key points.
1. Check whether the system is running properly before startup. Piping valves, pistons and cylinder pressure gauges shall work reliably and without leakage. The hydraulic valve that controls the oil circuit when the machine is started.
2. After the new machine is used for three months, the oil cylinder needs to be cleaned and the new oil needs to be replaced, generally half a year or once a year. When adding new oil, the winter oil 10 and summer oil 20 should also be filtered. Keep the oil level of the tank sealed and the oil temperature below 50 ° C. Open the valve regularly;
3. Ensure that the gauge pressure does not exceed the alarm threshold. Once the pressure gauge failure, please replace in time;
4. Keep the system clean and tight, check whether there is oil leakage, temperature rise, air leakage, vibration, noise, lack of pressure and other abnormal conditions, and find out the cause of timely elimination;
5. Avoid collisions and damage by inspecting, cleaning and replacing parts. Don't hit the fuselage with a hammer.
6. Normal oil pressure, feed should be uniform, should not be too much or too little, otherwise there will be idling. At this time, the machine load is normal, the operation is smooth, the sound is rhythmic. The filter cake is discharged smoothly. There is basically no residue in the low pressure section, and a little oil residue in the high pressure section, but the oil residue accounts for less than 10% of the oil. The temperature of the warm pressure room can reach 150-200℃, and the green smoke of the cake outlet must pass through. The shield is discharged from the smoke pipe. Please press the hot cakes flat in time, do not rush to stack or distribute, otherwise there will be natural phenomenon. When the continuous working time is long and the machine temperature is too high, cooling measures should be taken, such as blowing fans.
