Mechanical seal is one of the most basic mechanical components, pumps, compressors, motors and other devices there is a very common application. Mechanical seal on the requirements of high precision, mechanical seal installation or assembly process, we should always pay attention to the accuracy of the mechanical seal problems, the following is a mechanical seal installed a few points to note.

 1, precision mechanical seals installed in the grasp

 Mechanical seal is a very high precision components required in the installation of the mechanical seal mechanical seal must be strictly controlled and the precision of the machine to pump mechanical seal, for example, installation of mechanical seal in the shaft or sleeve, the radial runout Tolerance should be maintained at between 0.04 to 0.06mm, or mechanical seal in the device operation will be a problem.

 Mechanical seal pumps should also pay attention when installing the rotor axial movement of the range, usually is not more than 0.3mm. Mechanical seals and sealing the seal chamber cover position with face, and beating the surface of the shaft or sleeve tolerance must also have strict accuracy requirements, the maximum can not exceed 0.06mm.

 2, the mechanical seal installed in the seal confirmed

 Mechanical seal during installation of the seal to be confirmed by rigorous to ensure that after the installation of mechanical seals operating results. First, mechanical seal installation, make sure the installed seals and mechanical seals required equipment is the same model to avoid the mistakes caused by missed work equipment, etc. and equipment losses.

 Before the installation of mechanical seals, mechanical equipment assembly in accordance with plans, confirmation number is correct mechanical seal, parts are all in place. In addition, if the mechanical seal is used and circle the spring drive, but also in the rotation before installation to confirm the spring to keep the mechanical seal spring rotation line with the shaft of the options.
