摘要： PURPOSE:To contrive to restrain scattering of oil drop and discharge noise by providing a narrow passage for allowing exhaust gas, which is discouraged inside an exhaust gas reserving chamber, to flow out into inside of an oil case, on one face of the said chamber formed by providing walls for walling up five faces on an exhaust opening end face to surround the exhaust. CONSTITUTION:An exhaust gas reserving chamber 31 is constituted by providing a front wall 32, upper wall 33, both side walls 34, 35 and rear wall 36 for walling up five faces above an outlet opening end face 5a. Gas including oil drop ejected from intermediate outlets 29, 30 expands inside the exhaust gas reserving chamber 31, and comes to collide against each wall 32-36 many times resulting in being discouraged. The oil drop is separated from this gas in its process and the gas not including much oil drop flows out into inside of an oil case 2 through a narrow passage 37, at one side of the exhaust gas reserving chamber 31, for allowing exhaust gas discouraged inside the chamber 31 to flow out into inside of the oil case 2. As the result of this, it is made possible to efficiently restrain the scattering of the oil drop to outside of a pump and the discharge noise.

CONSTITUTION:A vacuum pump device is constituted to incorporate a rotary blade type pump 2 and a mechanical booster pump 3 integrally in a common pump case 1. Then, the rotary blade type pump 2 is constituted principally from a plurality of stators 21, 22, pump chambers S1, S2 and rotors 27, 28. Also, the mechanical booster pump 3 is constituted to receive a pair of root type rotors 34a, 34b mounted to a plurality of driven shafts 33a, 33b in a pump chamber S3. The respective pumps 2, 3 are interconnected by a timing belt 37 so that the mechanical booster pump 3 is driven by a motor 4 in interlocking relation with the rotary blade type pump 2.

摘要： PURPOSE:To effectively cool an oil rotary vacuum pump by forming part of oil case walls with a stator and allowing the wind fed by a cooling fan to hit this outer walls. CONSTITUTION:A cooling fan 24 feeding wind toward the stator 7 of an oil rotary vacuum pump is provided on the drive shaft 20 of the oil rotary vacuum pump encircled by a fan cover 23, on the other hand walls 8, 9 of an oil case 2 are formed with part of the stator 7. Since a gap 29 is formed between the walls 8, 9 of the oil case 2 and the fan covers 23, 27 the wind fed by the cooling fan 24 flows along the walls 8, 9 of the oil case 2, thus the whole oil rotary vacuum pump can be effectively cooled.

摘要： PURPOSE:To prevent the shortening of the life of a pump due to a testing liquid, by sending the specified amount of the testing liquid into a testing tank from a reservoir tank with the testing liquid being filtered, so that the specified amount of the testing liquid is always made to remain and held, and by decreasing the temperature of the testing liquid lower than that at the time of testing. CONSTITUTION:A testing tank 1 is filled with a testing liquid 2. The surface of the testing liquid 2 in a reservoir tank 10 is always kept lower than the bottom surface of the testing tank. Solenoid valves 9 and 14 are closed and a pump P is operated. Then the testing liquid 2 is injected into the testing tank 1 up to the liquid level indicated by a solid line. Presence or absence of the yield of bubbles is observed, and the quality of an IC device is judged. It is possible to decrease the temperature of the testing liquid considerably lower than that at the time of testing. An ordinary pump can be used. The life of the pump is not shortened by the testing liquid.

摘要： PURPOSE:To reduce the amount of oil, discharged together with exhaust gas to the outside of an oil reserving tank, effectively without increasing the size of the device by a method wherein a corrugated plate, disturbing the flow of the exhaust gas by moving it up and down, is provided at the fore stage of an exhaust port. CONSTITUTION:A chamber 16, communicating with the exhaust port 4, is formed at the upper corner of the oil reserve tank 1 while the bottom wall of the chamber is constituted by the corrugated palte 15. The corrugated plate 15 is consisting of first slanted plates 15a, whose lower surfaces are facing to the pump 2, and the second slanted plates 15b, whose lower surfaces are facing to the opposite direction of the pump 2, which are arranged alternately and continuously, while venting holes 17 are bored at the intermediate positions of the second slanted plates 15b respectively. According to this method, the exhaust gas A, containing a plenty of oil drops, collide against various parts of the corrugated plate when it flows to the direction of the exhaust port 4, and the oil drops are disturbed by changing their flowing directions and moving them up and down, therefore, the oil drops, mixed into the exhaust gas A are separated and returned into the oil reserve tank 1, thus, the amount of oil discharged to the outside of the tank 1 may be reduced effectively.
摘要翻译：目的：为了减少油量，排出废气到储油罐外面，有效地通过一种波纹板不会增加装置的尺寸而不增加装置的尺寸，该方法通过将瓦楞板向上移动来扰乱排气的流动设置在排气口的前段。构成：与排气口4连通的室16形成在储油箱1的上角处，同时室的底壁由瓦楞纸15构成。波纹板15由第一倾斜板 15a，其下表面面对泵2，并且其下表面面向泵2的相反方向的第二倾斜板15b，其交替地连续布置，同时排气孔17在中间位置钻孔的第二倾斜板15b。根据该方法，当排出口4向排气口4的方向流动时，含有大量油滴的废气A与波纹板的各部分相撞，油滴通过改变其流动方向和移动而受到干扰因此，混入排气A中的油滴被分离并返回到储油箱1中，因此可以有效地减少排出到罐1外部的油量。
