During the daily use of the hot press, in order to reduce the number of downtime due to equipment failure, we should pay attention to the maintenance of the equipment, so as to ensure the operating speed of the equipment and the quality of products. The following is a brief introduction to the daily maintenance of the hot press.

Daily maintenance methods for hot press:

1. Sealing ring for steam elbow. The rotary union of steam pipe of many hot presses adopts the sealing device of asbestos packing. The asbestos thread is soaked in polytetrafluoroethylene plastic and pressed in the original packing box to avoid steam leakage caused by hardening of asbestos packing under high temperature. The effect is good, but it is not convenient to use. When replacing the sealing ring, the ring behind the ball shall be cut off at an oblique angle of 45 ° before it can be put on, but the sealing effect will not be affected.

2. Maintenance of hot pressing plate of hot press. The upper and lower lining plates of the hot pressing plate can protect the surface of the hot pressing plate. The upper lining plate has a direct impact on the surface quality of the fiberboard. It is often easy to clamp fibers and other dirt between the lining plate and the hot pressing plate. The lining plate should be removed regularly to remove the dirt. The upper lining plate is generally replaced once a week to polish the surface and ensure the quality of the finished plate surface.

3. When installing the upper lining plate, the fiberboard shall be padded well before pressing. Damaged slabs or slabs of different sizes cannot be put into the hot press, and it is not allowed to directly press the fiberboard without the lining plate. When the hot press is stopped for a long time, the steam condensate in the hot press plate shall be removed in time to avoid internal corrosion.

4. The partial (or total) non heating of the hot pressing plate of the hot press indicates that the internal channel is blocked or there is a "short circuit" in the channel. At this time, it is necessary to open the channel of the exclusive deep hole drill for inspection and remove the obstacles before continuing to use.

5. If local steam leakage is found on the hot pressing plate of the hot press, it can be repaired and leveled by electric welding. After welding, the water pressure shall be tested, and the pressure shall be 1.2---1.4 times of the steam pressure. If the leakage is caused by serious internal corrosion, it should be replaced.
