Long-term use of the laser leveling machine will cause major and minor faults. When facing these faults, we must find a solution to the problem. A common problem is that the laser leveling machine hopper cannot be closed. When such a problem occurs, we must first find the root cause of the problem and find the answer to the problem based on the root cause. The following laser leveling machine manufacturer will reveal the reason why the laser leveling machine hopper cannot be closed.

Reason 1: Insufficient thrust of the hopper cylinder.

The laser leveling machine manufacturer will show you the reason that the hydraulic oil in the laser leveling machine hopper cylinder leaks. First, check the piston seal. Aging or wear of the seal will cause insufficient thrust of the hopper cylinder. Replace it if necessary. If there is no problem with the laser leveling machine seal, check the gap between the cylinder and the piston of the equipment. Cylinder wear can make the gap too large, making the thrust of the laser leveling machine hopper cylinder smaller. If it is found that there is no hydraulic oil in the laser leveling machine hopper cylinder during the inspection, it may be that the equipment overflow valve is faulty, causing it to be in an open state for a long time, so that no oil flows into the hopper cylinder. At this time, check whether there is dirt in the overflow valve.

Reason 2: Insufficient oil supply pressure of the hydraulic pump.

The laser leveling machine manufacturer will let you know that it is generally caused by leakage of the laser leveling machine hydraulic pump. If the hydraulic pump itself is worn, it is internal leakage, and if the seal is worn, it is external leakage. If necessary, the worn parts should be replaced in time. In addition, if the hydraulic pump does not absorb oil due to too little hydraulic oil or the hydraulic pump oil filter is blocked, it will also reduce the oil supply pressure. At this time, the pump will make a loud noise when running, so it can be judged based on whether the meshing sound of the pump gear is normal.

Reason 3: The hydraulic pump is the same

The laser leveling machine manufacturer will let you know that the hydraulic pump that controls the closing of the left and right hoppers of the laser leveling machine and controls the lifting of the ironing plate is the same pump. If the left and right hoppers cannot be closed normally due to the hydraulic system, the laser leveling machine ironing plate will also have a corresponding failure. Therefore, if the hopper and the screed fail at the same time, the hydraulic pump failure should be the first thing to think of. As the standards of the construction industry continue to improve, more and more users begin to pay attention to high-precision floor construction, and a laser leveling machine product that focuses on precision and efficiency can be recognized by users to a large extent. Technology is important, and concepts are also important.

The knowledge points shared by the laser leveling machine manufacturer have deepened your impression. I hope this article can help you. Secondly, it is recommended that you regularly maintain and care for the equipment, which can reduce the number of repairs. Thank you for your continued attention and support.
