In making use of concrete pump vehicle, experience S pipeline valve does not turn or S pipeline valve swing weak what problem? Currently let's take a look at it.

The S Tube Shutoff Does Not Swing

1. The distribution shutoff touch-button mistake or the electrical wiring falls off;

2. The pilot shutoff spindle of the electro-hydraulic turning around valve is stuck or the electromagnetic iron coil is burned out;

3. The distribution shutoff is supported the foreign body; the fault of the pilot overflow shutoff makes the reversing stress insufficient;

4. Continuous pressure pump failing, to ensure that the change pressure can not meet the demands;

5. Concrete product distinction, downtime is long, adjustment resistance is large, do not move;

6. S pipe bearing wear, modification resistance;

7. For high-level pumping, the straight line is also short.

The S Pipe Valve Swing Is Weak

1. Not enough stress or harmed skin cavity in the accumulator. Reinflate the nitrogen gas pressure approximately 8.5 MPa, or change the new collector skin capsule to recharge the nitrogen gas to 8.5 MPa.

2. The dumping switch is not closed.

3. Swing the oil cyndrical tube for oil leakage.

4. The spool of the pilot overflow valve is drastically used to make the turning around pressure listed below 15 MPa.

The electro-hydraulic modification valve electromagnet failure or the primary valve spool springtime crack, to ensure that the primary valve spindle can not run in place: the primary shutoff spool of the electro-hydraulic change valve is worn, causing interior leak.

The S pipe shutoff swing is not in place

1. Swing cyndrical tube nylon birthing seat contortion or thickness. Readjust the gasket under the swing cyndrical tube nylon bearing.

2. Concrete solidification, too large concrete bits do not satisfy the pumping demands, or the hydraulic oil pressure is insufficient.

Distribution Valve Swing Arm End Leak Mortar

"S" pipe small end of the dust ring deformation or too much bearing wear, large clearance, check and also replace.
