Common faults and solutions of sand making machines

We not only need to choose a suitable machine but also to master the knowledge of machine operation. It can quickly troubleshoot the failure problems in the operation process and solve the failure to avoid unnecessary losses. Here, Vanguard Machinery summarizes some common faults and solutions of sand making machine for your reference.

Common faults and solutions of sand making machine:

1. Abnormal sound

Failure cause 1:There is metal in the feed.

Solution:Strictly screening of feed material, strengthen iron removal.

Failure cause 2:The guard plate or wearing parts are loose or slip off.

Solution:Check and tighten all connections.

2. Excessive vibration of the machine

Failure cause 1:The wearing parts of the throwout wheel are worn seriously.

Solution:Replace wearing parts.

Failure cause 2:uneven wear of wearing parts, unbalanced throwout wheel.

Solution:Adjust the position of wearing parts to balance the throwout wheel.

Failure cause 3:uneven feeding or too large particle size.

Solution:Adjust uniform feeding or feeding particle size.

Failure cause 4:The runner is blocked.

Solution:Remove the blockage.

3. The machine suddenly stops.

Failure cause:Due to abnormal oil flow, the power supply of the interlocking system is interrupted or stuck material.

Solution:Check the control components and power supply of the lubricating oil circuit, and remove the stuck material.

4. The too high bearing temperature

Failure cause 1:Bearing damage.

Solution:Replace the bearing.

Failure cause 2:Lack of oil.

Solution:Increase the oil intake.

Failure cause 3:The lubricating oil is dirty.

Solution:Clean the bearing and replace the lubricating oil.

Failure cause 4:Too high oil temperature.

Solution:Connect ventilation cooler.

The working principle of the sand making machine is shown:

5. The too small amount of oil

Failure cause 1:The sealing surface of the oil pump is worn.

Solution:Check the oil pump, replace the seals or replace the oil pump.

Failure cause 2:The system is blocked and the large resistance.

Solution:Clean the system.

Failure cause 3:System leakage.

Solution:Solution: Plugging.

6. The lubrication system does not supply oil.

Failure cause 1:Wrong turns of the oil pump.

Solution:Correct the rotation direction of the oil pump motor.

Failure cause 2:System blockage.

Solution:Clean the system.

7. The too high lubricating oil temperature

Failure cause:The air cooler is not working properly.

Solution:Turn on the air cooler.

8. Pulley belt heating

Failure cause:Conveyor belt is too loose.

Solution:Adjust and tension bolt and the belt.

9. The too large discharge particle size

Failure cause 1:The V-belt of the transmission part is loose.

Solution:Adjust the belt tension.

Failure cause 2:The too large feed particles.

Solution:Check the wear of the alloy hammer head and the side impact plate of the sand making machine from time to time, and replace the wearing parts; Check the feeding granularity of the material and strictly follow the feeding requirements of the sand making machine.

Failure cause 3:The too low and unreasonable impeller speed, resulting in low efficiency and larger particle size.

Solution: Adjust the speed of the impeller until it meets the requirements.
