Product Description

Industrial Mechanical Seal Easy Spare Parts CN K1 For Centrifugal Pump

Mechanical Seal


Mechanical seals are seals for rotating mechanical shafts, such as centrifugal pumps, centrifuges, reactors, and compressors. Because the transmission shaft passes through the inside and outside of the device, the peripheral gap between the shaft and the device, the device leaking the medium passes through the gap. If the internal pressure of the device is lower than atmospheric pressure, air will leak into the device, so there must be a Method to prevent leakage of shaft seal equipment. There are many types of shaft seals because mechanical seals have the advantages of less leakage and long life. Therefore, mechanical seals are the main shaft seals of these devices.
The definitions of seals, mechanical seals, and end faces in the relevant national standards are as follows: through the action of the fluid pressure and elastic (or magnetic) compensation mechanism in at least one pair of end faces perpendicular to the rotation axis, and cooperation with the auxiliary seal, Incorporate devices that slide relatively and prevent fluid leakage. "

Installation Precautions

1. Assembly must be clean and smooth. The parts of mechanical seals, related machinery and equipment parts, tools, lubricating oil (grease), wipe materials (cotton yarn, white cloth, silk, etc.) must be very clean. The sealing end face of the dynamic and static ring should be wiped with white silk or soft gauze.

2. Trimming and chamfering of chamfers, shafts, sealed end caps, etc. shall be trimmed smoothly, and the relevant corners of the shaft and end caps shall be sanded and polished.

3. During installation, apply turbine oil or l0 oil on the moving ring and static ring (especially on the seal end blood), auxiliary seal ring, shaft, and end cap to reduce friction, so as not to damage the seal of the static ring. End faces and auxiliary seals.

4. Assemble the auxiliary sealing ring.
1) Rubber auxiliary seals cannot be soaked and washed with gasoline or kerosene to avoid swelling and deformation and premature aging.
2) After the O-ring is installed on the moving ring assembly or static ring assembly, it should be logical to prevent it from being twisted, so that the burr is in the cross-section when it is free. O-rings that are slightly rough on the burr can be used if the burr segment is 45o. However, care should be taken in the position of the burrs. When pushing the component, one side of the O-ring and the seal (gland or seal cavity) slide relative to each other. The burr on the side should be behind the sliding direction. Otherwise, the burr will be turned up and sealed. In position, it affects the sealing effect.
3) When pushing the assembly, prevent the O-ring from being damaged. The main forms of damage are drop, nick, bump, curl and twist.

5. Adjust the mechanical seal compression amount according to the technical requirements. For the value, refer to the product manual. Otherwise, the amount of compression is too large, which increases the specific pressure on the end face and accelerates the wear of the end face; if it is too small, the specific pressure on the end face of the moving ring and the dense ring is insufficient, and the seal fails.
6. The static ring assembly should be installed into the gland (or sealed cavity) using a press or a drilling machine. Under no circumstances should mechanical seal parts or components be impacted. The pressed surface should be covered with clean paper or cloth to avoid damaging the sealed end.

7. After assembling the moving ring or static ring assembly, press the compensation ring by hand to check whether it is installed in place and whether it is flexible; elastic split ring (in some mechanical seals, the elastic split ring axially positions the compensation ring) Reliable positioning.

8. Check whether the perpendicularity between the sealed end and the centerline of the shaft (or shaft sleeve) meets the requirements.

9. The anti-rotation pin lead of the static ring component must be accurate. When pushing the static ring component, the pin groove of the component must be aligned with the pin. After pushing in place, the distance from the end surface of the component to one end of the sealed cavity is determined to determine whether it is in place.

10. When tightening the end cap by tightening the bolts, use even force, symmetry, and care. Tighten it several times. Do not tighten it at one time to avoid skewing or even crushing the static ring.

11. After the moving ring is installed, it must be ensured that it can move axially on the shaft flexibly (press the spring with the moving ring and then spring back freely).
