In the installation of single-stage slurry pump, be sure to follow the relevant instructions to implement, otherwise it will bring less duplication of effort. Today, Xiaobian to share single-stage slurry pump for you to install steps and points, hoping to help you! Single-stage slurry pump installation points, single-stage slurry pump installation steps 1. Check the installation of the slurry Pump mechanical seal models, specifications are correct. 2. Check the size of the parts associated with the installation of the mechanical seal and mechanical seal accuracy, geometric accuracy and correlation with the technical requirements. (1) Allowable radial runout of the shaft (or sleeve) where the mechanical seal is installed, surface finish of the shaft (or sleeve), and tolerance of outside diameter dimensions. (2) seal cavity and gland positioning end face of the shaft (or sleeve) centerline vertical tolerance tolerance. (3) The end of the shaft (or sleeve) on which the moving ring seal is mounted, and the chamfer and finish of the end structure of the housing bore for the mechanical seal. (4) The axial displacement of the mechanical seal shaft when working. 3. During the installation of the slurry pump, keep it clean and do not allow the tool to beat the sealing element to prevent damage and damage. 4 installation, moving, static ring surface should be coated with a layer of clean oil and turbine oil. Auxiliary seals (including moving ring seals and static ring seals) are also to be applied with a clean layer of engine oil or turbine oil before installation to ensure smooth installation. 5. The static ring seal set in the back of the static ring, into the sealed end cap, pay attention not to hurt the static end face, to ensure the static end face and end cap vertical centerline, and pay attention to the back of the static ring to prevent trough to Alignment anti-sales, but can not touch. 6. Rotating part of the mechanical seal, relying on the two fixed screws on the spring seat and the shaft fixed, tighten the screws, to ensure the working length of the spring.

A flange can also be a plate or ring to form
a rim at the end of a pipe when fastened to the pipe. A blind flange is a plate
for covering or closing the end of a pipe. A flange joint is a connection of
pipes, where the connecting pieces have flanges by which the parts are bolted
together.
Although the word flange generally refers to
the actual raised rim or lip of a fitting, many flanged plumbing fittings are
themselves known as 'flanges':
There are many
different flange standards to be found worldwide. To allow easy functionality
and interchangeability, these are designed to have standardised dimensions.
Common world standards include ASA/ASME (USA), PN/DIN (European), BS10
(British/Australian), and JIS/KS (Japanese/Korean). In the USA, ANSI stopped
publishing B16.5 in 1996, and the standard is ASME B16.5
