Concrete Block Making Machine Factory

As the core equipment of a brick-making production line, the operating status of brick making machines directly affects product quality, production efficiency, and enterprise profits. In actual production, equipment failures often occur unexpectedly, while many problems are foreshadowed. This article, combining common failure types and daily maintenance experience, compiles a practical repair and parts management plan for on-site operators and managers. I. Common Failure Types and Simple Troubleshooting Methods 1. Sensor Failure Sensors are the "eyes" of the brick making machine's automatic control system. When equipment malfunctions or a workstation becomes unresponsive, the first thing to suspect is whether the sensor is working properly. The troubleshooting method is very simple: check the human-machine interface of the control box, enter the input/output monitoring screen, and observe whether the signal status of the corresponding sensor is normal. If the sensor signal is abnormal, check whether the wiring is loose, whether the sensor head is obstructed by foreign objects, or whether it is damaged. This usually allows for quick location of the problem. 2. Product Parameter Deviation and Uncontrolled Base Material Moisture This is one of the most common problems in production. When brick blanks exhibit dimensional deviations, insufficient strength, or appearance defects, it's often not a problem with the equipment itself, but rather a change in formula parameters or raw material moisture content. In such cases, it's recommended to immediately record a clear video of the brick-making process and send it to the equipment manufacturer. Professional technicians can remotely observe the brick's condition to determine whether the issue lies in the ingredient ratio or equipment parameter drift, and then make targeted adjustments. In most cases, remote guidance from the manufacturer can resolve the problem, eliminating the need for on-site repairs and significantly reducing downtime. 3. Hydraulic System Abnormalities The hydraulic system is the core power source of the brick machine. When the equipment experiences insufficient pressure, sluggish operation, or oil leaks, first check if the hydraulic oil level is normal, if the oil temperature is too high, and if the cooling system is functioning. Before starting the machine each day, turn on the pressure gauge to confirm that the working pressure meets the set value. If the hydraulic oil is found to be deteriorated or the oil level is low, replenish or replace it with the same type of hydraulic oil promptly. Never mix different brands or grades of oil.   II. Daily Maintenance System   Establishing a regular maintenance system is the most effective way to extend equipment life and prevent sudden malfunctions. Weekly Essentials – Lubrication and Maintenance The guide sleeve is a precision-fitting part of the brick machine's up-and-down movement. Lubricate it at least once a week to ensure smooth movement and reduce wear. Also, check the cleanliness and lubrication of all moving parts, including bearings, guide columns, and gear racks. Every 2-3 Months – Vibration Box Oil Change The vibration box is the heart of the brick machine, and the quality of its lubricating oil directly affects vibration efficiency and equipment lifespan. Under normal circumstances, the lubricating oil in the vibration box should be completely changed every 2 to 3 months. Lubricating oil will be consumed normally during daily use and must be replenished promptly; the oil level should be maintained between 30 and 40 mm. Also, check that the hydraulic motor rotation direction is correct, confirming it according to the equipment markings. Incorrect direction can cause serious damage to the vibration system. Belt and Bolt Inspection The drive belts on the entire machine should be inspected frequently. Adjust or replace them promptly if wear, slippage, or loosening is found to prevent power transmission failure due to belt malfunction. In addition, check the tightness of all bolts before each start-up, especially the connecting bolts of high-frequency vibration parts such as the vibration box and pressure head; loose bolts can cause a chain reaction of damage.   III. Precautions for Machine Operation Standardized operation is the first line of defense against malfunctions. The following are key points to follow during daily operation: 1. Before starting the machine, check that the power supply is normal, all bolts are tightened, and all lubrication points are lubricated. 2. Check the hydraulic oil level, oil temperature, and the operation of the cooling system. 3. At the start of work, turn on the pressure gauge to check if the working pressure meets the standard. 4. Check that the vibrator oil level is between 30-40mm and confirm that the hydraulic motor rotation direction is consistent with the marked direction. 5. Keep all moving parts of the machine clean and lubricated, paying particular attention to bearings, guide columns, and gear racks. 6. The belt must be checked frequently. If there is wear, slippage, or looseness, it should be replaced or adjusted promptly. 7. During production, pay attention to the material adhering to the pressure plate. If necessary, stop the machine to clean it to avoid affecting the quality of the brick blanks. 8. Strictly follow the equipment requirements for lubrication. Replenish the lubricating oil in the vibrator promptly when it is consumed. 9. When the equipment jams, first turn off the oil pump before troubleshooting. Never force operation. 10. After each day's work, clean and dry the machine, apply lubricating oil, and never wash the equipment with water.   IV. Fault Diagnosis and Remote Support Modern brick machine control systems are equipped with automatic fault display functions. During production, please enter the output display screen. When a fault occurs, this screen will display a prompt box indicating the location of the fault and troubleshooting methods. Users can try to troubleshoot themselves according to the prompts. If the problem persists, contact the equipment manufacturer for remote technical support. Never force the machine to start when the fault is unclear, as this may cause a small problem to escalate into a major malfunction.   V. List of Consumable Parts and Stockpiling Recommendations Brick machines have many types of consumable parts. Maintaining a reasonable inventory of spare parts in advance can reduce downtime from "several days" to "several hours" in the event of a fault. The following is a summary of the main consumable parts for each system: Main Unit: Pressure Head Bolt, Spring Mould 20, Mold Cabinet Screw. Vibration components: Rubber pads, rib oil seals. Material cart components: Material cart axle, swing arm, stirring fork, stirring pin, material cart bearings, wire brush. Hydraulic station components: Single proportional valve, directional valve, cylinder oil seals. Electrical control components: Small relays, sensors, photoelectric sensors, illuminated buttons, emergency stop switches. Spare parts recommendations: Keep 2-3 sets of electrical control components such as sensors, photoelectric sensors, small relays, and emergency stop switches readily available, as their failure rate is high and damage renders the equipment inoperable. It is recommended to keep 2 sets each of sealing components such as cylinder oil seals, rubber pads, and rib oil seals, as aging and leaks will severely affect equipment performance. Keep 2-3 sets each of easily worn mechanical parts such as pressure head bolts, material cart axles, and stirring forks; these are inexpensive but require frequent replacements upon damage.         VI.Conclusion The maintenance and management of brick-making equipment ultimately boils down to three things: prevention first, timely inspection, and readily available spare parts. Sensor malfunctions and parameter deviations are often the first signs of system alarms or product quality abnormalities, requiring operators to possess basic judgment skills. Weekly oiling, quarterly oil changes, and daily cleaning—these seemingly tedious daily tasks are precisely the most effective ways to prevent sudden downtime. For brick-making companies, instead of anxiously waiting for repairs after equipment failure, it's better to spend an extra ten minutes in daily management checking and stocking up on a few extra critical spare parts. A well-maintained brick machine is not only a guarantee of production efficiency but also the cornerstone of stable product quality.  Check out our website for more information: https://www.yxbrickequipment.com
