Symptom and solution for hydraulic system troubleshooting

Symptoms
High pressure below expectations

CAUSES
Excessive friction loses in the system. Oil speed limit

Corrections DESIGN
 Use as little pipe arches. Hold the ideal radius of the pipe and pipe bends. Port Areas, holes

Corrective measures
Hoses and pipes should comply with the oil rate of 15 frames per second at pressure lines. 10 fps for the return lines.

Symptoms
Frequent dropping courses

CAUSES
Vibration machines.

Corrections DESIGN
Design more brackets

Corrective measures
Oil executives firmly attached. More Support

Symptoms
Overheated oil (active normal operating temperature is about 130 ° 140 ° degrees F).
CAUSES
1.Too much oil to blow through the pressure relief valve. (Pump too large for the system)
2.Insufficient oil or oil is too low.
3.Highpressure help too long.
4.Oil too bright
5.Obstructions or decrease the flow
6.Oil in pipes

Corrections DESIGN
1.Pump capacity must be at least 10 to 15% higher than the requirements.
2.Increase capacity at least 34 times the oil tank pump.
3.Use small pump for high pressure
4.Specify right SSU oil.
5.Avoid sharp bends in the pipe, particularly in copper pipes.
6.Specify ideal bending radius.

Corrective measures
1.Check safety valve for pressure and leakage. Check the pressure at the pump to function. Add a heat exchanger.
2.Add oil
3.And high volume pumps for low pressure.
4.Use heavier oil.
5.Check position valves for neutral and congestion.
6.Pump components can be worn. Check back pressure valve for high pressure.
