Hydraulic fluctuation causes unstable injection pressure and speed
Problem Phenomenon
Hydraulic fluctuation causes unstable injection pressure and speed
Cause Analysis
Hydraulic oil temperature too high, system pressure fluctuation
Hydraulic oil contamination, valve core sticking
Hydraulic pump wear, unstable flow
Accumulator pressure insufficient, slow response
Hydraulic pipeline leakage, pressure loss
Solution
Control hydraulic oil temperature 35-45°C
Regularly replace hydraulic oil and filter elements
Maintain the hydraulic pump
Check accumulator pressure
Check hydraulic pipeline leaks
Key Takeaway
The hydraulic system requires regular maintenance and oil temperature control
