Embodiment Construction

[0017] A pressure conversion device according to the present invention, such as figure 1 , figure 2 , image 3, Figure 6 and Figure 7 As shown, it consists of two fixed end bodies 1 connected with a rotating main body 2 . Wear-resistant ceramic 3 is used for mechanical seal between the fixed end and the rotating body, and other wear-resistant materials can also be used, such as tungsten steel, stainless steel or steel plated with wear-resistant chromium, and then vacuum ion-plated titanium nitride or titanium nitride film, etc. . Between the two fixed end bodies, a cylindrical shell 4 is fixedly connected. The two fixed end bodies 1 are respectively provided with a wear-resistant ceramic 3 , a water inlet 5 , a water outlet 6 and a support seat 7 . The cylinder body 8 is formed by connecting two cylinders with different inner diameters. The inner wall of the cylinder is required to be smooth and wear-resistant, and is equipped with two sealed and slidable terminals 9 ...

Abstract

The invention discloses a pressure conversion device which comprises fixed end bodies, a main rotating body and a shell and is characterized in that the main rotating body is a rotatable mechanism consisting of at least two cylinder bodies while a coupling spindle is arranged at the center of the mechanism. A bearing and fixing plates used for fixing the cylinder body are arranged on the couplingspindle. Seal rings are arranged between the cylinder bodies and the fixing plates at two ends; two cylinders with different inner diameters are connected to form the cylinder body and respectively and internally provided with a terminal which can slide in a sealed status. The two terminals are mutually connected by shaft sealing; the two fixed end bodies are respectively provided with a water inlet and a water outlet. The pressure conversion device can be used for the conversion of the pressure between liquid, the conversion of the pressure between liquid and gas, or the conversion of the pressure between gases, therefore, the full utilization of energy and the reduction of energy loss can be realized so as to save costs, reduce resource waste and protect the environment.

Description

technical field [0001] The invention relates to a pressure conversion device, in particular, it can be used for pressure conversion between liquids, or between liquids and gases, and can also be used for pressure conversions between gases. Background technique [0002] At present, in the process of pure water treatment, seawater desalination, wastewater treatment, pharmaceutical, food concentration, precious metal recycling in chemical waste liquid, water recycling, etc., especially in the process of membrane osmosis treatment, multi-stage high-pressure pumps are usually used to transfer low-pressure liquid It becomes a high-pressure liquid and penetrates through RO membrane and nanofiltration membrane to purify the water or concentrate the liquid. Due to the high pressure requirements, the energy loss is very large. At the same time, the processed liquid is directly discharged, which wastes a lot of energy. Contents of the invention [0003] The object of the present in...
