What are the precautions for installing the seal of the automatic double-end grinder


  Full-automatic double-end grinding machineThe seal is a device that keeps the end surface (friction pair) perpendicular to the rotating shaft and slides relative to the rotating shaft under the action of the fluid pressure and elastic force of the compensation mechanism and the cooperation of the auxiliary seal, thereby preventing fluid leakage. One more friction pair than single-sided mechanical seal. The two friction pairs may be composed of two moving rings and two static rings respectively, or may be composed of two moving rings sharing one static ring or two static rings sharing one static ring. This article introduces the installation steps and precautions of the automatic double-end face grinder seal.

1. Clean the rotating shaft and sealing cavity first.

2. During the installation process, the sealing device of the automatic double-end grinder should be kept clean, especially the sealing surface and the surface of the auxiliary sealing ring should be free of impurities and dust. It is not allowed to wipe the sealing surface with unclean cloth and other objects.

3. Apply lubricating oil or soap on all O-rings installed in the sealing device of the automatic double-end grinder (note: ethylene-propylene rubber materials cannot contact mineral oil) to facilitate the smooth installation of the mechanical seal.

4. When installing, pay attention to distinguish the installation direction of the left and right fixing rings and the shaft sleeve. When installing the automatic double-end grinder seal to prevent the axial displacement of the fixing ring, the snap ring needs to be placed in the corresponding position of the sealing cavity

5. During the installation process, it is strictly forbidden to hit or knock the seal violently to prevent damage to the seal of the fully automatic double-end grinder. The friction surface should be kept clean and should not be coated with any oil.

  6、Full-automatic double-end grinding machineAfter the seal is installed, turn the rotating shaft by hand to check whether there is friction between the static ring, gland and shaft sleeve, and between the rotating part and the seal cavity. When the pump shaft rotates a circle, the pump shaft should feel the force evenly. If the rotation is not possible or the local force is high, please check whether the seal has installation problems. If necessary, disassemble the pump to find the problem, and reinstall it when it is resolved.

Installation and commissioning of double-sided grinders Before installing and using the machine tool, you need to understand the installation, commissioning, operation and other matters in the manual in detail. The machine is well installed on the pouring foundation. The ground needs to be flat and firm, and the anchor bolts need to be fixed to avoid the working vibration of the machine.

1. Fully automatic double-end grinder: After installation, clean up the anti-rust materials of each part of the machine tool, then add mechanical lubricating oil on the sliding surface and guide rail, and then turn the hand wheel and grinding disc by hand to check whether the rotation is normal.

3, access to tap water.

4. Check whether the circuit, control element, fuse and connector are loose or disconnected.

5. The machine tool needs to be reliably grounded, and the power can be turned on only after the inspection is correct.

6. Press the main power button, and then press the workbench button to move the workbench back and forth.

7. Press the grinding head button and immediately press the stop button. The rotation direction of the grinding head should be consistent with the direction of the calibration arrow, and reverse rotation is not allowed.

8. Pull the manual and automatic handles on the lower side of the grinding power head to check whether it is flexible. Otherwise, add lubricating oil to the sliding part, and then pull it several times. The impact blocks on both sides of the worktable are used to adjust the automatic feed speed of the grinding wheel. The feed speed of each grid of the lead screw is 0.25mm. The feed speed is adjusted according to the hardness of the sample. The large extent of each section of the lead screw does not allow more than three grids. When leaving the factory, the automatic feed speed of the grinding head is adjusted to one grid at a time.

9. Open the water switch on the workbench fixture, and the cooling water should be sprayed with sufficient flow.

The above is the introduction of the relevant contents of the automatic double-end grinding machine. Hope it can help you.
