Germany Baode overflow valve product sales introduction
The main reasons for pressure fluctuations caused by Baode overflow valve:
1The screw that adjusts the pressure causes the pressure of the lock nut to loosen due to the vibration; 2The hydraulic oil is not clean, there is tiny dust, so the main spool is not flexible. This produces irregular pressure changes. Sometimes the valve will be stuck; 3 the main spool is not smooth, causing the damping hole to block when passing; 4 the main valve cone conical surface is not in good contact with the taper of the valve seat, without good running-in; 5 main spool damping The hole is too large, does not play a damping role; 6 pilot valve adjustment spring bending. The valve core and the cone seat are not in good contact and the wear is uneven.
Baode BURKERT relief valve repair common troubleshooting methods:
1 Regularly clean the fuel tank, pipeline, and enter the fuel tank, the hydraulic oil of the pipeline system should be
filtered; 2 if there is a
filter in the pipeline, the secondary
filter element should be added. Or replace the
filtering accuracy of the secondary components; remove and clean the valve components, replace the clean hydraulic oil; 3 repair or replace the unqualified parts; 4 properly reduce the damping aperture.
The pressure of the Baode overflow valve system is completely unacceptable:
A: 1 The main spool damping hole is blocked. If the main valve core is not cleaned, the oil is dirty or assembled with debris; 2 the assembly quality is poor, and the assembly accuracy is poor during assembly. The gap between the valves is not well adjusted, the main spool is stuck in the open position, and the assembly quality is poor;
3 The main spool return spring is broken or bent, so that the main spool cannot be reset.
Baldor BURKERT relief valve repair failure common solutions:
1 Disassemble the main valve cleaning orifice and reassemble it; 2
filter or replace the oil; 3 tighten the bonnet fastening screw to replace the broken spring.
B: Pilot valve failure, 1 adjustment spring is broken or not installed, 2 cone valve or steel ball is not installed, 3 cone valve is broken.
Solution: Replace the damaged or replenished parts to return the pilot valve to normal operation.
C: The remote control solenoid valve is not energized (normally open type) or the slide valve is stuck.
Baode BURKERT relief valve repair common troubleshooting method: check the power line, check whether the power is connected; if it is normal, it may be that the slide valve is stuck, and the failed parts should be repaired or replaced.
D: Hydraulic
pump failure: 1 hydraulic
pump coupling key off or rolling; 2 sliding surface gap is too much; 3 vane
pump blades are stuck in the rotor slot; 4 blades and rotor direction are reversed; 5 springs in the blade Subject to high frequency cyclic loading, fatigue deformation or breakage.
Solution:
1 Replace or re-align the joint key and repair the keyway; 2 repair the gap between the sliding surfaces; 3 remove the cleaning vane
pump; 4 correct the wrong direction; 5 replace the broken spring.
E: The inlet and outlet ports are reversed and adjusted.
3. System pressure is not high
