Introduction

MVR is the abbreviation of mechanical vapor recompression technology. ZQRSR series products are steam compressors specially developed by our company for MVR system. High temperature steam corrosion and leakage are two main problems in the use of steam compressor. Based on our accumulated experience for many years, we have summarized the solution of 2205 stainless steel+mechanical seal. SS2205 has better chemical and mechanical performance than SS304 or 316. Mechanical sealing can 100% prevent the leakage of steam from the shaft.

Shangu Steam Compressor Advantages

1）Shangu brand Roots MVR Steam Compressor adopts the assembled double-end professional mechanical seal to avoid seal failure and leakage of steam.Various materials such as the duplex stainless steel (2205),super duplex stainless steel (2507), Hastelloy and austenitic stainless steel(316，316L only for shell-wall plating and cast iron plating) can be designed according to the user’s choice which can effectively prevent internal corrosion of steam compressors.

2）Shangu series Roots steam compressor have have large air volume and large boost pressure coverage,and the product has a wide range of applications.The user can choose the applicable compressor.The processed capacity of the steam is 30-1500OKG, and boost temperature of the steam is 10-25 ℃.

3）The compressors are simple in structure, stable and reliable in operation, high in mechanical efficiency, easy to maintain.It is insensitive to dust, droplets and fibers contained in the steam to be transported: There is no lubrication on the rotor surface and the steam can not be polluted by the oil.

4）The impeller adopts a new profile, which has good sealing performance, smaller intenal leakage, and high efficiency and energy saving.The product has high processing precision, reliable operation and long service life.Independent cooling system protects high temperature components during shutdown.

5）The specific internal clearance of the rotor prevents the thermal expansion of the rotor caused by different materials from exceeding the residual gap value and internal friction occurrence.

6）The bearing adopts imported brand bearings,such as NSK or SKF, to ensure the precise positioning of the impeller and high stability during operation

7）The pulley adopts the expansion sleeve type with European standard, with long service life.The coupling (direct transmission) adopts standard high-strength elastic coupling,and the elastic component is made of rubber material with high quality.

8.With 5-100HZ variable frequency motor, the adjustment range of speed is wider, and it is more suitable for working condition.
