Quotation analysis of high-pressure Roots blower
High pressure Roots blower is a special type of Roots blower, mainly used in situations that require high air pressure, such as pneumatic conveying, blast furnace blowing, chemical reactions, etc. Its price is usually higher than that of ordinary Roots blowers. The following analysis will focus on technical characteristics, application areas, and price influencing factors.
##1. Technical features
The main difference between high-pressure Roots blowers and ordinary Roots blowers lies in their design and working pressure. High pressure Roots blowers usually adopt multi-stage compression design, which can provide higher air pressure, usually above 50kPa, and even up to 100kPa. Due to its high work pressure and higher requirements for materials, manufacturing processes, and sealing performance, the price is relatively high.
##2. application area
High pressure Roots blowers are widely used in the following fields:
-Pneumatic conveying: used for conveying powdered or granular materials, such as cement, flour, chemical raw materials, etc.
-Blast furnace blower: Provides high-pressure air to the blast furnace to promote combustion.
-Chemical reaction: Providing high-pressure gas for chemical reactions such as oxidation, hydrogenation, etc.
-Wastewater treatment: Used for high-pressure gas supply to aeration tanks to improve oxygen utilization efficiency.
##3. Price influencing factors
The price of high-pressure Roots blower is affected by the following factors:
-Power and Wind Pressure: The higher the power and wind pressure of a fan, the higher the price. For example, a high-pressure Roots blower with a wind pressure of 80kPa may be priced more than 50% higher than a regular blower.
-Material and Process: High pressure Roots blowers are usually made of high-strength cast iron or stainless steel, with higher manufacturing process requirements, resulting in higher prices.
-Brand and Configuration: High pressure Roots blowers from well-known brands have higher prices, but their quality and after-sales service are guaranteed. In addition, the price of fans equipped with accessories such as frequency converters, mufflers, and filters will also increase accordingly.
-Market supply and demand: During periods of strong demand, prices may rise; In cases of oversupply, prices may decrease.
##4. Price Range
According to market research, the price range of high-pressure Roots blowers is relatively large. For example, a high-pressure Roots blower with a power of 22kw and a wind pressure of 80kPa is usually priced between 30000 and 60000 RMB; A high-pressure Roots blower with a power of 55kw and a wind pressure of 100kPa may cost as much as 80000 to 120000 RMB.
In summary, the price of high-pressure Roots blowers is influenced by various factors such as power, wind pressure, material, brand, and market supply and demand. Users should choose the appropriate model based on their specific needs and pay attention to market trends when purchasing to obtain cost-effectiveness.
