To prevent confusion, the top and bottom of each SNL vertical bearing seat are marked with the same number for identification.
Markings to aid installation: SNL vertical bearing seat bases have casting markings to indicate the axial location of the housing holes for easier installation and more accurate alignment. In addition, there are marked holes for mounting other components, such as locating pins, sensors for condition monitoring, or adding other nozzles.
Mounting Methods for Vertical Bearing Seat
The mounting method for vertical bearing seat consists of the following steps:
Bearing heating: First, the bearings are uniformly heated to approximately 120 degrees Celsius, which helps to avoid deformation of the bearings due to excessive temperature differences during mounting. Heating can be carried out using an electric hot plate, induction heating or other appropriate methods.
Measure the clearance between the bearing end cap and bearing: Measure the clearance between the bearing end cap and bearing by pressing the lead wire method, use the copper pad to adjust the axial clearance 0.1~0.15mm, and then install the bearing end cap.
Mounting the bearings: After the bearings have been heated, tap the inner ring of the bearings into place using a brass rod. Then, use a stopper to check the clearance between the bearing and the shaft to make sure there is no clearance.
Installation of impeller: Before installing the impeller, it is necessary to carry out the keying treatment to ensure that the impeller and the shaft are more closely matched to avoid water leakage and other problems.
Install the pump end cover: When installing the end cover bolts, it is necessary to cause misalignment on the diagonal to ensure that the installation of the end cover is more stable.
Install the pump: Install and center the pump on the pump slide. Then, check the coupling clearance with a plug ruler and straightedge to ensure that the pump is installed in the correct position to avoid leakage and other problems.
The working principle of vertical bearing seat is to enable the bearing to be mounted and rotated through the combination of seat and base, so as to realize the normal operation of mechanical equipment.
A vertical bearing seat is a support device mounted on mechanical equipment to support and enable the shaft to rotate freely. It usually consists of a housing and a base. The housing is the part that holds the bearing, while the base is a fixed pedestal used to support the housing. The housing usually has a circular hole inside the housing body that is sized to match the diameter of the outer ring of the bearing, thus ensuring that the bearing can be accurately mounted in the housing. The design of the housing body also takes into account the positioning and sealing of the bearing to ensure the stability and reliability of the bearing during operation. The base is the fixed base of the bearing housing and is used to support the housing and fix it to the mechanical equipment. The base is usually made of a metal material with sufficient strength and rigidity to withstand the working load. The bottom of the base usually has pre-drilled holes for fixing bolts to facilitate the fixing of the bearing seat to the equipment.
The role of the bearing housing mainly includes support and friction reduction. In mechanical equipment, rotating shafts are often subjected to loads and rotational forces from external sources. Bearing housings ensure the normal operation of rotating shafts by bearing and transmitting these loads, distributing the external loads to the bearings, and converting them into bearing support forces through the bearings in linear motion. In addition, bearing housings provide lubrication and sealing, ensuring proper lubrication of the bearings by supplying lubricant to the bearings and maintaining an efficient supply of lubricant through the seals.
Structural Characteristics of Vertical Bearing Seat
Enhanced base design: SNL vertical bearing seat have increased support and wall thickness around the coupling bolt holes, which makes the bottom vertical block stronger, improves the positioning ability, and avoids deformation of the seat holes caused by excessive force.
Bearing connection: Standard SNL vertical bearing seat are provided with two coupling bolt holes, and larger size housings can be provided with four coupling bolt holes for easy installation and fixing.
Good cooling effect: The increased support of the housing also increases the surface area between the housing and the supporting surface, which helps to take away more heat from the bearing and maintain a good working temperature.
Re-lubrication device: Standard SNL vertical bearing seat are equipped with oil nipples, which are easy for maintenance personnel to re-lubricate and keep the bearings and seals lubricated.
Identification marks on top cover and base: The top cover and base of vertical bearing seat are machined together at the time of manufacture and must be used in conjunction with each other. To prevent confusion, the top and bottom of each SNL vertical bearing seat are marked with the same number for identification.
Markings to aid installation: The base is provided with casting markings to indicate the axial location of the seat holes for easier installation and more precise alignment, as well as marked holes for mounting other components, such as locating pins, sensors or adding other nozzles, simplifying the installation process1.
