According to the customer's use situation, after the long-term use of each high and low temperature test box, the equipment will face a problem that the door seal is not strict. What is the so-called door seal is not it? It is behind the high and low temperature test box door Long seal aging deformation, or due to improper installation and careless opening and closing doors, vibration transport, local seal dents, deformation caused by gas spills. How to deal with it? Here's to follow along with Aisi Xiaobian to see it . 1, if the high and low temperature experimental box door seal S-shaped inside bending, can be sealed with a ruler, and then use the hair dryer in front of the curved part of the slightly heated, the plastic slightly softened to stop heating, high and low temperature test chamber door seal cooling, and then remove the ruler, The seal can be restored to its original state. It should be noted that the use of hair dryer heating, the temperature is not too high, otherwise it will soften the door plastic, blistering and deformation. When heated, 700W hair dryer application, should be controlled at 1min, and distance Should be about 3 cm. 2, when the high and low temperature test box seal the middle and due to low temperature caused by the gap, the dryer is the gap. Manually pull out the seal rubber mat recess. When the gap is lost, the rest 20min can be. 3, will be closed loosely sealed in the door to gently pry open, take some cotton carefully collapsed into the loose part of the closed part, the number of filled cotton, to the door just difficult to shut tight. Because the cotton itself is elastic, can guarantee the door seal and box Body fit. Editor's Note: Magnetic door seals for high and low temperature test cases , such as poor sealing, will directly affect the leakage of the test box resulting in changes in the cooling effect and increase power consumption, but also easily cause the compressor to start rekindling again. Therefore, do not underestimate this problem. Can not really solve this problem or to find some professional manufacturers to repair it better.
Seal face is a typical and classical sealing form. Due to SiC, AL2O3 ceramic have superior hardness, anti-wear, anti-chemical, resistant high tempreture and pressure and low friction with self-lubrication characteristics. It have been recognized a excellent material for seal face.
Ceramic seal face work as a sealing component through a fine finish treatment surface with greatest ideal flatness, very smooth working sides. Commonly, it used in some water pump, oil pump, centrifuge.
