Electrical device

section

Hydraulic part

1. Oil pressure must be kept above 80kg/cm ²

2. The accumulator must maintain a nitrogen pressure of 75-80 kg/cm ² (supplemented when insufficient)

Lubrication system

1. Does the machine pipe and oil pump have oil leakage?

2. Frequent inspection during operation, oil pressure, oil quantity and lubrication of individual bearings

3. Always check the circulation of lubricating oil. The general oil quantity should be maintained at 1/3 to 1/2 of the return pipe.

Various parts of the body

1. Screw tightening of each part

2. Adjust the ring fixing device for looseness

3. Check the base, upper shell and spring runout

4. Check if the tablet is loose

5. Pay attention to whether the transmission gear sound and vibration are normal.

6. Whether the ore is even or biased to one side, and whether the ore discharge size meets the requirements

Dustproof system

Check the water flow of the dust water

Electrical system

Check the motor temperature rise (≤60 °C) current, odor, vibration, etc. and the operation of the electronic control system

Fault phenomenon

cause of issue

Elimination method

Crusher springs often

Being fatigued or sometimes broken

Spring screw broken

1. Unbalanced or excessive ore

2. Too many pieces in the ore

3. The discharge port is blocked by wet or sticky ore very small

4. Too much iron loss

5. The spring pressure is not enough

6. The spring strength is not enough

1. Adjusting the mine

2. Strengthen screening

3. Strengthening washing equipment

4. Strengthen iron selection measures

5. Press the spring but not exceed the specified maximum compression

6. Adjust according to actual conditions

With the fierce sound, the upper part is lifted up and then turned into normal

Falling into the broken cavity into the iron block or other non-broken objects

Strengthening iron selection equipment and hand selection measures

Gear overshoot

1. Gear meshing is improper

2. Bearing clearance is too large

3. Gear wear is too high

4. Lost teeth

5. The gear keys are loose

6. Gear machining error is too large

1. Adjust the gap

2. Adjust or replace

3. Replace

4. Repair or replacement

5. Reinforcement and key change

6. Repair or replacement

Strong noise during crushing

1. Broken wall loose

2. The rolling wall is loose

3. The bolt or hook on the fixed cone is broken

1. watered regularly checked again when the degree of filling and compression nut fastening zinc alloy where necessary fastening

2. Tighten the nut on the pressure plate to re-water the zinc alloy when it is loose.

3. Stop and remove the adjustment ring to replace it.

Noise when idling

The broken wall or the rolled wall is not rounded to produce impact or friction

Re-adjust gap or machining

Suddenly the two walls touched each other during the rotation

1. The two walls are loose

2. Vertical axis break

3. Spherical bearing damage

4. Hard iron block is stuck between the two walls

1. Fasten or refill zinc

2. Replacement

3. Replace

4. Take out

Hoarse sound, motor

Rotating the broken cone rotates too fast

1. Large gear or pinion damage

2. Vertical axis break

3. Gear roll button

4. The drive shaft is broken

Replace

2. Replacement

3. Change key

4. Replace

Crusher strong vibration

The broken cone rotates too fast

The vertical axis is stuck for several reasons

1. Lack of lubricating oil or oil is too dirty

2. The moving cone is broken or the spherical bearing is damaged.

3. The gap in the tapered bushing is not enough

Downtime to identify the cause to be eliminated

Broken shaft or gear teeth

Serious iron loss

2. Two walls meet

3. Hold the shaft

4. The amount of spring compression is too large

5. Conical bushing is not tapered

6. Poor gear processing quality

Water supply

2. Adjust the water pressure

3. Cleaning

Water mixed into the oil

Water pressure is higher than oil pressure

Adjustment

Eccentric shaft rises, disc

Pins may be eccentric shaft slots

Fall out
