What is the spectacle plate of concrete conveying pump?
Often heard people ask: what is the glasses board in the end?
Is it used to protect the eyes when operating the pump? Sound ~ ~ In fact, the glasses just look like glasses, is not used to protect the eyes of the.
Concrete long what kind of, Taichang company small set out to show you see will understand In fact, the glasses board also has a more professional name, that is wear-resistant plate, just because of the appearance and glasses very much like, so the people’s image called the glasses.
Don’t underestimate the gadget, the spectacle plate is an important part of the concrete conveying pump, although the volume is not large, but the technical content and processing cost are quite high. At present, the life of the spectacle plate is about 30,000 M2 of concrete, which is the key to improve the use efficiency of the arm-frame pump.
The eyeglass panel is part of the S-shaped pump distribution valve, connecting with the commercial concrete conveying cylinder, the moving part s tube is driven by the oscillating cylinder, from one side the commercial concrete cylinder swing to the other side of the commercial concrete cylinder, the cutting ring with the s tube is attached to the glasses plate, and the glasses Board is composed of the switch friction pair. Note: 1. Sieve 2. Stirring device 3. Swing Arm 4. Screw 5. Profiled Bolts 6. Cutting Ring 7. Rubber Spring 8. Spectacle Plate 9.
As a result of the rapid swing of the cutting ring so that the glasses and premixed concrete to produce strong wear, but also to bear the impact of cutting stones produced by the shock, the spectacle plate is mainly at room temperature to withstand impact, shearing force and very strong friction. The spectacle plate belongs to the wearing parts, and its main failure forms are wear and the wear of the broken block failure spectacle plate and the cutting ring, which belongs to abrasive wear. First of all, the cutting ring and the hole edge of the glasses plate are blunt, and form a small circular-arc wedge-shaped mouth, with the increase of abrasive particle size, the wear gap increases.
When the gap is large to a certain value, it will affect the construction due to serious leakage. With the increase of pump height, the impact shear of glasses plate will increase, wear more intense, and prone to fragmentation collapse. When the spectacle plate is damaged or invalid, we must change it in time to ensure the normal operation of the whole concrete conveying pump equipment.
