Talk about what you don’t know: On the importance of refrigerator magnetic seals How many people were the same as me when I was young Slowly close the refrigerator door to see when the lights inside go out How did it go out Trial and error Only later discovered It turns out there is a switch in the refrigerator When the magnetic seal in the refrigerator is close to the ref
Refrigerator sealing strip replacement is not complicated, you can replace it yourself 1. When the door seal of the refrigerator is damaged, deformed, twisted, weakened in elasticity, many cracks, not strong in magnetism, and there is stolen goods that cannot be cleaned, you should choose to replace the door seal. 2. The door seal is damaged, deformed, and after aging, the refrigerator will not
Temperature setting for different materials of extruder The extruder sets different temperatures due to different materials, the following are the processing temperatures of various extruded materials: A, PP, PE materials are generally extruded at temperatures between 150℃-230℃; B. PVC core wire materials are generally extruded at temperatures between 130℃-190℃; C. PVC outer quilts are general
The difference between two temperature control methods of extruder equipment The temperature control system of the extruder and extrusion equipment is different according to the type of extruder. The two common temperature control methods are air cooling and water cooling. The extruder is divided into several temperature zones according to different models, generally divided into the barre
In the process of twin-screw plastic extruder extrusion, the causes of various problems may be solved in time. I have compiled some common questions for your reference. 1. Low lubricating oil pressure during the operation of the twin screw extruder The main reason for the low lubricating oil pressure is that the pressure setting of the lubricating oil system regulator valve is too lo
What is the working principle of the twin screw extruder Working principle diagram of twin screw extruder One. Basic structure and working principle The commonly known screw refers to a twin-screw extruder. The basic structure of screw compressor: A pair of intermeshing spiral rotors are arranged in parallel. Compressor body. Called the male rotor or male screw. A rotor with concave teeth
Main technical parameters of twin screw extruder ① Screw diameter: refers to the outer diameter of the screw, in mm. For a changing diameter or tapered twin screw, this is a variable value and it should be indicated which end diameter. The screw diameter of the twin screw extruder is 28~340mm. The larger the diameter, the greater the extrusion capacity of the characterizing equipment. ②Scr
How to deal with the emergency stop failure of twin screw extruder There are two main disposal methods for twin-screw extruders during emergency parking: abnormal parking and emergency parking. The important steps are as follows ① Normal parking. When the extruder is stopped without failure, it can be stopped in the following order: close the hopper discharge gate; adjust the feeder speed
