目的を達成している。 The basic structure of the present invention for achieving the above object is that the first sliding member is composed of a first member and a second member fixed to the shaft side and rotates together with the shaft, and the first sliding member is fixed to the pump body side and consists of a second member. It has a second sliding member disposed to form a sliding surface with a first member of the sliding member, and an annular groove is provided in the sliding surface of the second sliding member to form a sliding surface. A space chamber is formed in the space chamber, and the space chamber divides the sliding surface between the two sliding members into a first seal surface on the outer periphery of which cooling water is adjacent to the first seal surface and an inner periphery of the second seal surface on which atmospheric pressure acts. Further, a through hole is formed in the first member of the first sliding member, one end of which is open to the space chamber, and a through hole is formed in the surface of the second member of the first sliding member facing the first member between the holes. A plurality of blades are provided so that the other end of the through hole is open, and when the shaft rotates,
Leakage water and water vapor from the first seal surface that entered the space pass through the through hole and are released to the outside due to multiple effects, causing the second seal to be depressurized.
This achieves the intended purpose of improving the sealing effect of the sealing surface.

ないとう利点がある。 In the above configuration, a space chamber is formed in the second sliding member to divide the sealing surface between the first and second sliding members into two, and a special configuration is used to divide the sealing surface into two. No parts are required, and the formation of through holes and vanes can be easily done by machining the component parts of conventional equipment, which has the advantage of not increasing the number of parts or expanding the space of the equipment. be.
以下、本考案の一実施例について、添付図面に
基づいて説明する。尚、この実施例の説明に当つ

案の実施例を示す。 Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. In the description of this embodiment, the same parts as those of the mechanical seal device shown in FIG. FIG. 2 is an enlarged view of section A in FIG. 1, showing an embodiment of the present invention.
第２図に於いて、第２摺動部材６の第１摺動部
材の第１部部材３ａとの摺動面に溝を設けて空間
室９が形成され、該室９の形成により両部材３
ａ，６間に形成されるシール面が、第１シール面
１０と第２シール面とに分割される。更に、第１
摺動部材の第１部材３ａには両側面に開口しその
一端が空間室に開口する貫通穴１２が形成され、
第１摺動部材の第２部材３ｂの第１部材３ａとの
対向面にはその間に貫通穴１２の他端が開口する
ように複数の羽根１３が形成されている。 In FIG. 2, a space chamber 9 is formed by providing a groove in the sliding surface of the second sliding member 6 and the first member 3a of the first sliding member, and by forming the chamber 9, both members 3
The sealing surface formed between a and 6 is divided into a first sealing surface 10 and a second sealing surface. Furthermore, the first
A through hole 12 is formed in the first member 3a of the sliding member, and the through hole 12 is open on both sides and one end thereof is open to the space chamber.
A plurality of blades 13 are formed on the surface of the second member 3b of the first sliding member facing the first member 3a so that the other end of the through hole 12 opens therebetween.
貫通穴１２は、第３図に示される様に、第１摺
動部材の第１部材３ａに同一円周上に所定間隔を
もつて形成され、また羽根１３も同様に第１摺動
部材の第２部材３ｂの同一円周上に所定間隔をも
つて形成されている。 As shown in FIG. 3, the through holes 12 are formed in the first member 3a of the first sliding member at predetermined intervals on the same circumference, and the blades 13 are similarly formed in the first member 3a of the first sliding member. They are formed at predetermined intervals on the same circumference of the second member 3b.
さて、シヤフト１の回転時に、水室１４より微
少量の漏れ水や水蒸気が第１シール面１０より空
間室９に侵入すると、羽根１３の遠心作用により
空間室９内の水滴や水蒸気は貫通穴１２を介して
外部に放出される。その結果、空間室９内の圧力
が下がり、第２シール面１１が減圧されることに
なるので、第２シール面１１からの水漏れを著し
く少なくすることが可能となり、メカニカルシー
ル装置のシール作用が大きく向上する。 Now, when the shaft 1 rotates, if a small amount of water or water vapor leaks from the water chamber 14 and enters the space chamber 9 from the first sealing surface 10, the centrifugal action of the blades 13 causes the water droplets or water vapor in the space chamber 9 to flow through the through hole. 12 to the outside. As a result, the pressure inside the space chamber 9 is reduced and the second sealing surface 11 is depressurized, making it possible to significantly reduce water leakage from the second sealing surface 11 and sealing action of the mechanical seal device. will be greatly improved.
