HT series high temperature and high pressure Roots fan


Product description:

HT series high temperature and high pressure fan is a product specially designed for the working condition as a circulating fan in a closed system.

In order to maintain a higher reaction efficiency in such systems, there are often higher temperatures and pressures in the system. Since the main material of the Roots blower is generally made of cast iron, the material may be annealed or even graphitized at high temperature, and there is a hidden danger of the body explosion under high pressure. The general rubber seals are prone to aging and failure at high temperatures. At the same time, bearings under high temperature conditions are prone to bearing failure due to the transformation of the metallographic structure of the material. These conditions put forward a series of harsh Claim.


HT series high temperature and high pressure Roots fan


The HT Roots blower dedicated to high temperature and high pressure has been specially optimized and improved for the above conditions. Creatively proposed an open-type, water-cooled integrated bearing housing structure. The open-type body is used to relieve the high pressure while avoiding the transmission of high temperature to the bearing, and the risk of flashover caused by the leakage of the lubricant in the gear box into the body is eliminated. The existence of the water-cooled structure adds double insurance to the protection of the bearing, which effectively improves the stability of the body, extends the life, and reduces the temperature of the whole machine.

At the same time, HT high-temperature and high-pressure fans, a large number of mechanical seals and PTFE seals are used to effectively avoid the defects of ordinary rubber parts that fail at high temperatures.

The following is the process schematic diagram and achievable parameter standard of HT high temperature and high pressure fan for special working conditions.
