High pressure blowers features
High-pressure air blowers are notable for their exceptional ability to create a substantial pressure differential compared to standard models with similar performance capabilities. Let's delve into the methods employed by these advanced blowers to achieve this feat.
The maximum pressure capacity of ring blowers is primarily constrained by temperature limitations. During the compression process, the gas undergoes significant heating, reaching temperatures that could cause thermal deformation of metals, lubricant degradation, and gasket failure. Consequently, effectively managing temperature removal becomes crucial when operating under high pressure conditions.
One can readily observe the disparity in cooling systems when comparing low-pressure blowers with their high-pressure counterparts. High-pressure blowers utilize a more efficient and sophisticated cooling fin system, enabling uninterrupted operation even at the highest pressure differentials.
In high-pressure air blowers, the bearing, being the most critical component, experiences the highest load. Excessive exposure to temperature can easily impair the bearing due to thermal deformation of its parts, as well as degradation or evaporation of the lubricant. To address this, we exclusively employ high-precision bearings from a specialized series designed for high-temperature applications in our VH models.
The VH series of ring blowers are manufactured with one, two, and even three stages of compression. The utilization of multiple stages allows for an extended air compression path, enabling the attainment of maximum pressure differentials of up to 410 inches H2O. Furthermore, the multi-stage compression yields a flatter characteristic curve, ensuring stable performance even under significant pressure differentials.
Vacuum Pump Blower
The substantial pressure differential generated by high-pressure blowers makes them suitable for use as vacuum pumps. Standard blower series impose limitations on working with closed volumes, prohibiting prolonged evacuation of systems that lack a fresh air supply. This restriction is due to the aforementioned temperature limitations, as the compression unit relies on fresh air for effective cooling. In contrast, high-pressure blowers incorporate a more efficient cooling system, enabling extended operation for pumping closed volumes. Moreover, with a greater high vacuum capability of up to -280 inches H2O, these models can effectively compete with various types of vacuum pumps.
High pressure blowers application
High-pressure blowers are used in the most demanding applications where a large pressure difference is required. Such applications include:
