Maintenance principle of unfired brick making machine

Exmork brick making machine and block forming machine refers to a series of technical measures taken for the machine to keep the machine in a good technical state, ensure its reliability, improve work efficiency and extend its service life. Its main contents are cleaning, tightening, lubrication and adjustment, combined with relevant inspection and testing work. There are clear maintenance regulations for various types of mechanical equipment in the "Operation and Maintenance Manual", but in actual work, this is often not given enough attention, mainly manifested in: 

① There is a "repair instead of maintenance" idea. There is no technical maintenance plan at all, and the machine often works with "diseases". Only when the machine can no longer work, it is sent for repair. 

② Due to the restrictions of the harsh environmental conditions of the construction site, the technical maintenance is not carried out according to the prescribed "quantity" of maintenance, but what is thought of and what is seen is maintained. 

③ The quality of the personnel participating in the maintenance is low, and they cannot follow the maintenance operating procedures, and there is no corresponding maintenance record. 

④ When funds are relatively scarce, maintenance cannot be carried out on time, or non-compliant oil and spare parts are used. 

⑤ When the construction period is tight, in order to catch up with the progress, maintenance is not carried out as scheduled, and the operation of the machine is forced to be ignored, etc.

The unfired brick making machine should be regularly maintained and serviced to ensure safe production, improve the production efficiency of the unfired brick making machine, bring more economic benefits to the operator and create greater value. The following are the basic methods for the maintenance and service of the unfired brick making machine.

First , the specific matters of customer operation should first carefully read the manual of the unfired brick making machine, and implement it in action after understanding it, so that the unfired brick making machine can be used smoothly and freely, give full play to the various superior performances of the brick making machine, and extend its service life. In this way, maintenance can be reduced, and more qualified products can be produced.

Second, the main line of the power supply of the unfired brick making machine should be 25mm2 or more aluminum wire or 16mm2 or more copper wire according to the different models of the brick making machine. The input voltage of the brick making machine during normal operation is: high voltage 380V-410V, low voltage 330V-360V. The brick making machine must be installed with reliable grounding to ensure the safety of the operator. If the grounding device is not installed as required, it is easy to cause electric shock and personal injury.

3. The failure of the pressure regulating valve of the Exmork unfired brick making machine is caused by the damage or failure of the pressure spring in the pressure regulating valve of the brick making machine; [the pressure spring of the same type should be replaced in time]

4. If the oil cylinder of the unfired brick making machine is found to be leaking, the reason is that the seal inside the cylinder has lost its sealing effect; [the seal of the corresponding model should be replaced]

5. The oil pump motor of the unfired brick making machine is blocked or has difficulty in turning, which causes the motor to burn out. The reason is that the pressure of the main pressure regulating valve of the brick making machine [the large nut under the distributor] is too high. [The main pressure regulating valve of the brick making machine should be gradually reduced until the motor does not have difficulty turning when it is working normally.]

6. The vibration force of the vibrator [vibration box] of the unfired brick making machine is insufficient, the brick-making cycle is long or the bricks are loose and low in density. The reason is that the pressure adjustment of the lower mold of the brick making machine is too large; [The pressure adjustment of the lower mold of the brick making machine is too large, and the pressure inhibits the vibration of the vibrator. The pressure of the independent pressure regulating valve corresponding to the oil pipe on the lower mold cylinder should be gradually reduced until the vibration force of the brick making machine can be fully exerted]

8. The reason why the mold, balance arm and other parts of the main machine are welded or damaged is that the pressure adjustment of the lower mold is too small; [The pressure adjustment of the lower mold is too small, and the pressure cannot lock the lower mold, resulting in excessive impact force between the brick-making machine mold and the vibrating table, causing excessive damage to various parts of the entire equipment. The pressure of the independent pressure regulating valve corresponding to the oil pipe on the lower mold cylinder should be gradually increased until the vibration force of the machine is stabilized to reduce damage to the machine]

9. When the unfired brick making machine produces bricks , the surface of the bricks is loose, the bricks are broken, or the upper mold is lifted up by the lower mold when the bricks are removed . The reason is that the pressure of the upper pressure head is too low; [The pressure of the upper pressure head is too low, and the bricks cannot be positioned, resulting in loose brick surfaces. The pressure of the independent pressure regulating valve corresponding to the oil pipe on the upper pressure head cylinder should be gradually increased. While the brick making machine lifts the lower mold, gently move the wrench of the upper mold to keep the upper pressure head cylinder at a certain pressure, which can keep the bricks in the lower mold from rising with the mold, thereby reducing the breakage rate of the bricks.]

10. If you find that the bricks are bulging in the middle when the brick making machine is producing bricks , the reason is that the pressure of the upper pressure head cylinder of the brick making machine is too high, or the vibration time is too short, and the upper mold fails to press in place. [If you find that the bricks are damaged and uneven, you should pay attention to lifting them gently when the brick making machine supports the mold, or check the humidity and proportion of the aggregates. If it is too wet, a lot of water will be pressed out of the bricks when they are produced quickly. If it is too dry, the bricks will not be formed and cannot be produced.]
