??Learn how to install rubber seals mechanical seal

??Different options of different models of performance rubber seals, rubber seals rubber seals mechanical seal can be installed in the working conditions and the nature of the medium has a high temperature, low temperature resistance, mechanical seals, high pressure, corrosion-resistant mechanical seal, resistant to particulate media, should Depending on the selected use of different types of structures and materials installed on the mechanical seal.

??Rubber seals according to the mechanical seal chamber pressure (MPa), Grundfos mechanical seal fluid temperature (?), working speed (m / s), fluid characteristics and installation space, effectively sealing performance of different manufacturing rubber seals .

??The basic principles of mechanical rubber seals for the selection:

??1. In accordance with the mechanical seal seal chamber body pressure to determine the seal structure using flat type mechanical seal balanced or unbalanced type, single face or double face like.

??The operating speed of the mechanical seal to determine applicable to rotary or static, fluid dynamic pressure type non-contact type of mechanical parts.

??3. The temperature and fluid properties, determine the appropriate mechanical seal circulation protection system material and other requirements.

??4. The effective seal installation space, determining a built-in or externally mounted product size.

??Grundfos mechanical seal rubber seals press stationary ring sealing face located inside or outside can be divided into: built-in and external mounted. Media leaks by sealing direction of the rubber seals can be divided into: the loss of inner and Outflow. Logarithmically seal face can be divided into: single face and double face. By non-contact mechanical seal Category: Hydrostatic type, hydrodynamic, dry air sealed. Press the sealed chamber temperature classification: high, medium, general, low temperature seal. Press the seal chamber pressure separation: high, high, medium and low pressure mechanical seal

??Mechanical seal on the machine precision requirements (to pump mechanical seal for example)

??Radial (1) the installation of mechanical seal double mechanical seal parts of the shaft (or sleeve) of the jitter tolerance of the cartridge mechanical seal no greater than 0.04 ~ 0.06mm.

??(2) axial movement of the rotor is not more than 0.3mm.

??(3) the seal cavity and seal cap knot light mechanical seals co positioning end face shaft (or sleeve) surface runout tolerance maximum of 0.04 ~ 0.06mm.

??(1) confirm the installation of the seal is consistent with the requirements of the model.
