There are formats such as mathematical formulas, but by connecting two-stage and one-stage formulas,
There are various connection methods, such as connecting formulas to each other. In any case, the vacuum Roots blower is a dry operating type that does not use sealing oil, so there is no need to use a check valve, and there is no problem such as backflow of oil mist due to failure of the check valve when the operation is stopped. There is no problem at all, and the outlet of the Roots blower in the front stage is connected to the suction port of the Roots blower in the rear stage.
It is a multi-stage connection type that connects via hoses, pipes, etc.
0 Torr~0. Because it is easy to obtain a high vacuum of around 1 Torr, it has come to be used in a wide variety of applications, including vacuum drying of food and vacuum packaging.

When the pressure is reduced from 5 Torr to 260 Torr, the discharge gas temperature becomes approximately 150°C, and when the pressure is reduced from 5 Torr to 2 Torr, the temperature becomes over 300°C. It must be cooled by passing water through it, or by passing cooling water processed by a very large-scale cooling machine such as an electrically operated one.

If a cooler is used in conjunction with a cooler, it becomes more difficult to increase the size. However, there is no cooling water passage in the shell,
Although there is a method of cooling the outer periphery of the shell using the above-mentioned type of cooling machine, it is difficult to increase the size and cost, and there are many problems related to cooling that need to be solved.

Connect the discharge port of the vacuum Roots blower at the final stage to the suction port of the final stage vacuum Roots blower with a heat exchanger LH1F)7 flexible hose that is immersed in cooling water, and immerse each stage vacuum Roots blower in the cooling water at the 1st or top end. 1. A cooling device for a vacuum multi-stage connected Roots blower, which is characterized in that it performs a vacuum-operated multi-stage connected Roots blower without using the rock. Showa year, month, day 1, case description Japanese Patent Application No. 60-1862222, title of invention Cooling device for vacuum multi-stage connected Roots blower 3, person making the amendment Relationship with the case Applicant name Title Anret Co., Ltd. 4, agent 6 , Target of amendment Specification 7, Contents of amendment As shown in the attached document, 7M patent application 186222/1986 Contents of amendment 1, "Three-stage series" on page 5, line 14 of the specification has been replaced with "Three-stage series" ” he corrected. 2. Insert the following information between lines 15 and 16 on page 6 of the specification. ['I & It is possible to connect the discharge port (15b) of the final stage vacuum blower directly to the atmosphere discharge port (9). In that case, the position of the atmospheric discharge port (9) should be lower than the water level of the cooling water. 3. On page 8 of the specification, lines 5 to 7 of ff1fJ are corrected as follows. [Figures 2.4 to 6 show a vertical roots blower that is long in the vertical direction, but a model that is larger in the horizontal direction may also be used. A J eraser can also be installed in each cooling box. "that's all
