What are the matters needing attention in installing the full-automatic double-end face grinder seal


InstallationFull-automatic double-end grinding machineWhat are the sealing precautions

全自动双端面磨床

The seal of the automatic double-sided grinder keeps the end surface perpendicular to the rotating shaft and sliding relative to the rotating shaft under the action of fluid pressure and the elastic force of the compensation mechanism, thereby preventing fluid leakage. The friction pair has more than one mechanical seal. The two friction pairs may be composed of two moving rings and two static rings, or may be composed of two moving rings sharing a static ring or two static rings sharing a moving ring. The installation process and precautions of the automatic double-end face grinder sealing device are introduced.

First, clean the rotating shaft and the sealing chamber. During the installation and construction process, the sealing system device of the automatic double-end grinder should be kept clean, especially the sealing surface and the surface of the auxiliary inspection seal ring material should be free of impurities and dust. It is strictly forbidden to wipe the sealing surface with unclean cloth and other objects. Apply lubricating oil or soap to all o-rings installed on the automatic double-end grinding machine seal processing device to facilitate the smooth installation of our mechanical design seal. When installing, pay attention to distinguish the installation direction of the fixed ring and sleeve of the left and right enterprises. InstallationFull-automatic double-end grinding machineWhen sealing, in order to prevent the relative axial displacement of the company's fixed ring, it is necessary to place the snap ring at the corresponding different positions of the sealing cavity. During the installation and management process, it is strictly prohibited to collide or knock the seal to prevent damage to the seal of the full-automatic double-end grinder. Friction problems The surface should be kept clean and should not be coated with any oil.

Full-automatic double-end grinder: After the full-automatic double-end grinder is sealed and installed, rotate the rotating shaft by hand to check whether there is friction between the static ring, gland, shaft sleeve, rotating part and the sealing cavity. When the pump shaft rotates once, the pump shaft should feel a uniform force. If the seal does not rotate or is partially stressed, check that the seal is installed correctly. If necessary, remove the pump, find the problem, repair and reinstall. Before installing and using the machine, you need to understand the installation, commissioning, operation and other matters in the manual in detail. This machine is very suitable for installation on the pouring base. The ground is flat and firm, and the anchor bolts are fixed to avoid machine vibration. Fully automatic double-end grinder: After the installation is completed, clean up the anti-rust materials of each part of the machine, then add mechanical lubricating oil on the sliding surface and guide rail, and then turn the handwheel and grinding disc by hand to check whether the rotation is normal.

  Full-automatic double-end grinding machine: Press the grinding head button, the rotation direction of the grinding head should be consistent with the direction of the calibration arrow, and reverse rotation is not allowed. Pull the manual and automatic handles under the power head of the mill to check the flexibility. Otherwise, in the sliding parts of the oil, pull 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 was adjusted according to the hardness of the sample. A wide range of guidewire screws is not allowed for more than three eyes per segment. When leaving the factory, the automatic feed speed of the grinding head is adjusted once at a glance. Turn on the water switch on the table and spray the cooling water with sufficient flow. The above is the relevant content of the automatic double-end grinding machine.
