| Coil spring compartment | Sheet metal roll welding process | Uses seamless industrial pipes | |
| Advantage | Compared with sheet metal coil welding, seamless industrial pipes eliminate welding defects. The batch production consistency is very high, ensuring the cylindricity and concentricity, and eliminating the spindle jam. The sealing surface of the coil spring bin and the coil spring bin cover adopts machining processing technology to ensure flatness, the cross section is flatter, and the pipe wall thickness is about 9mm. The combination of the two greatly improves the sealing of the coil spring bin. | ||
| High precision double bearings | Single bearing | High precision double bearings with oil seals | |
| Advantage | The product uses high-precision double bearings and is equipped with oil seals, which greatly improves the sealing performance and obtains IP67 protection grade report | ||
| Spring | 301 stainless steel
Narrow | 301 stainless steel
Wide | |
| Advantage | The spring material is 301 stainless steel, with a lifespan of >12,000 times. The equipment lifespan is 10 years.
The spring material is 301 stainless steel, which can completely resist the erosion of the coil spring by the water vapor generated in the coil spring chamber due to the large temperature difference between day and night.
"Spring relaxed state-fully tightened state-relaxed state" is 1 time, and the test breaks 12,418 times. A test report can be provided.
Assuming the actual working conditions, the storage tank is full-empty-full once a day, 365 times a year, 12,418/365=34 years. If the safety factor is 0.4, 34*0.4=13.6 years, the equipment life can exceed 10 years. | ||
| Shell thickness | 2mm | 4mm | |
| Advantage | More durable | ||
