Abstract

PURPOSE:To adjust the interference of a spring and at the same time align a rotary ring with a non-rotary ring by providing an auxiliary sleeve having a contact surface brought into contact with a casing cover to regulate the axial and radial position, which is fitted on the atmosphere side of a rotary shaft. CONSTITUTION:An auxiliary sleeve 10 is fitted to the atmosphere side of a rotary shaft 4 in such a manner as to axially move on a set collar 6. The auxiliary sleeve 10 is cylindrical and has the first contact surface 11 and the second contact surface 12 brought into contact with a casing cover 1 on the casing cover 1 side. The first contact surface 11 is brought into contact with a surface ortogonal to the axis of a contact groove 13 formed on the casing cover 1 so as to regulate the axial position of the cover 1. The second contact surface 12 is formed on a projecting portion 14 radially projected on the auxiliary sleeve 10, and brought into contact with a surface of the cover 1 parallel to the axis thereof to regulate the radial position of the cover 1.

The purpose is to provide a mechanical seal that eliminates the spigot of the casing cover. Mechanical tar is a well-known method that prevents leakage by sliding the sealing ring between the rotating ring and the non-rotating ring. As the weight of Toi is 1, the spring tightening allowance is adjusted to adjust the contact pressure between the rotating ring and the non-rotating ring, and the 11 rotating ring and the non-rotating ring are adjusted to be almost concentric. If the spring tightness is not appropriate, leakage and seizure will occur, and if the axis of the rotating ring and non-rotating ring is not aligned,
1) In the case of large diameter seals, high speed seals, or high pressure seals, the so-called ``misoperation'' occurs on the seal sliding surface (due to misalignment of the shaft center).

Set plate) (So) is installed to regulate the position of both ends of the set plate (!!0) K and P of the casing cover to adjust the spring allowance. Centering of the rotation with the fixed ring (3) is achieved by forming a locking ring (51) of the casing cover and fitting this into the stuffing box (A).

ニカルタールを提供しようとするものである。Also, when using a set plate tube, there is a drawback that a notch must be formed.Also, centering using a 1-inch ink hole (ISL) is done through a stuff ink box. , the misalignment of the axis of the shaft (4) and the stuffy ink box prisoner is the tel! 1 There is a drawback that the axes of the rotating ring (2) and the fixed ring (3) are misaligned, and this occurs in large machines where the rotary shaft is deflected and the center of the axis of the blower, etc., and the casing are misaligned. The core metal is precisely formed, which is a major drawback in the place metal.
In multi-stage pumps, multi-tube casings are assembled and piled up, so errors, play, or line machining errors in the connectors accumulate, resulting in large misalignment. As shown in Figure 1, Inro (51) has 11 ring turns (
2) The diameter of the rotating ring (2) must be made smaller in order to make it stick out more! However, there is a problem with the middle part due to lack of large rigidity, which causes distortion (5
1) Formation and the fitting process inside the stuffing box require high precision.
51) The parts had drawbacks such as breakage and jamming when installed during transportation.The present invention was made to improve the above-mentioned conventional drawbacks, so it is possible to adjust the spring tightness and to adjust the rotation ring and non-rotation ring. The purpose of the present invention is to provide a mechanical tar that can simultaneously perform centering and alignment, reduce the construction cost of inlay, and improve the accuracy of centering.

K! As explained above, according to the mechanical seal of the present invention, it is possible to adjust the spring tightness and center alignment at the same time using the auxiliary sleeve. Since the core metal fittings of the single rotation ring and the non-rotation ring are based on the stuffing box and directly on the rotating shaft rather than on the hole, the accuracy is extremely high. This method simplifies the manufacturing process, eliminates damage during transportation, and allows the diameter of the rotating ring to be increased. Also, there is no risk of the fixed ring touching the rotating shaft Klk and being damaged during installation, and since the auxiliary sleeve is on the atmospheric side, it is a must! It has excellent effects such as being able to check the state of the core depending on the situation.
