Self-priming pump mechanical seal installation elements

Check carefully before installing self-priming centrifugal pumps build adequate number of sealing parts, all components for damage, especially in dynamic and static ring without bumps, cracks and deformation and other defects. If you have questions, need to be repaired or replaced with new parts. Check that the hub or gland chamfer is appropriate, if not meet the requirements must be trimmed.
Mechanical container seals assembly of the various components and their related contact surfaces before installation with acetone or ethanol must be clean. Installation process should be kept clean, especially the dynamic and static ring and auxiliary sealing elements shall be free of impurities, dust. Dynamic and static ring coated with clean oil or turbine oil.
Gland on the coupling alignment should be performed after. Bolts should be tightened evenly to prevent the gland section skewed, with a feeler or a dedicated tool to check each point, the error is less than 0.05 mm. Check the gland and the shaft or sleeve OD with the gap (and concentricity), must be guaranteed four weeks evenly, with each point feeler tolerance is not greater than 0.10 mm.
Spring compression according to regulations, does not allow too large or too small phenomenon requiring error ± 2.00 mm in cross-section than the pressure increase over the General Assembly to accelerate the cross-section wear. Too small will result in less than the pressure can not play a role in sealing, spring after spring loaded seat to move flexibly. With a single spring to the attention of the spring rotation, the spring rotation axis of rotation should be in opposite directions. Fixed Length plastic seals Ring must remain flexible movement after installation, the ring is pressed against the spring should be able to automatically bounce back after.

No -contact gas lubricated mechanical seals is how to work it

In operation, the gas-lubricated mechanical seal without contact between the sliding surfaces of the two should be a layer of only a few voids Xie meter , in order to produce voids , non-contact type mechanical seal of the two sliding surfaces disengage one another . To achieve this, a three-dimensional ring groove made ​​to ensure that the air is static and dynamic play. Seal in the stuffing box pressure difference generated at the aerostatic effect, while the aerodynamic effects generated by the rotation . The resulting force balance lift and closed , thereby forming a width of 1 to 5 Xie seal gap .
Applied in the mixer without touching gas lubricated mechanical seals
The gas in the mixer using the non-contact type mechanical seal for the user has three major advantages : 1, no liquid leakage ; 2, the product quality is not affected ; 3 , on the reaction with little or no effect ;
Non-contact type mechanical high security bolt seals also has some other advantages . Include: 1 , the operation clean (GMP); 2, low friction loss ; 3 , the noise does not occur ; 4 , mechanical wear little or no wear . If the seal system used in the mixer for the above requirements , then such seal member is operable .
Pressure purposes, without contacting mechanical seals are usually used in vacuum conditions , up to 6bar.
Mechanical seal according to the user part of the liquid lubricated seal for many years experience in the use of liquid seal is not used in the past for each of the products are suitable for gas seals. The main factors to consider for sealing products with high sensitivity ( eg , sealing surface is touched ) . To counteract this effect , many types of research and the use of additional components, such as the patented flush mounting flange . When not contact mechanical seal sealing surface when the automatic alignment feature degradation , self- converted to gas consumption , the sealing surface is blown or is rinse. The mounting flange can be used for washing steel container , especially for the enamel container ( plastic container ) . Apart from the gas seal applications beyond the experience gained in the storage and use has also made a series of new insights. When the seal member to achieve its first time of change , and start using the ship between the pull tight seals member , may be after many years. Same time, various factors can influence the characteristics of the gas seal member . In the assembly accidentally add too much grease or oil - grease or oil into or penetrate into the sealing gap . Then , in use , thereby causing uneven gap , mechanical seal damage. According to experience mechanical seal at its beginning before use should be checked.

Hammer seal leakage and prevention measures

1 when the oil pressure in the low pressure without leakage , causes mounting surface roughness difference ----- improve the surface roughness 3.2 ~ 6.3umry point with low hardness seals
2 larger piston oil ring , each one will be a few drops of oil stroke , causes the dust seal lip scraped film replacement wiper ring patterns.
3 at low temperatures, high temperatures do not leak oil , there are two causes one is too eccentric kind is inappropriate choice of seal materials , selection of cold seals can solve the problem .
The second category seals are not normal circumstances .
1 main oil seal surface hardening , the sliding surface cracks ; reason ----- abnormal high pressure is too high.
2 main oil seal surface hardening , the entire seal security seals broken , broken ; reason ---- hydraulic oil deterioration oil abnormally elevated ozone damage resulting from leaking seals .
3 main oil seal wear like a mirror-like surface smooth ; reason ---- Micro tiny stroke era pressure is too high .
4 main oil seal surface of the mirror uneven wear seals have swelling phenomena ; reason ---- eccentric side pressure is too large too large, use of improper oil and cleaning fluid.
5 main oil seal sliding surface for damage and wear scar ; reason ---- plating is poor, there is rust tie rod surface roughness improper selection of materials containing impurities.
6 top of the main oil seal lip scar rupture indentation ; reason ---- chamfer improper assembly , installation, improper storage methods .
7 main oil seal sliding surface indentation ; reasons ---- possession of foreign debris.
8 main oil seal lip cracks cracks ; reason ---- oil improperly, high or low temperature , high speed is too high back pressure , pulse pressure is frequently too large .
9 There are carbonized charred main oil printed cable ties  deterioration ; reason ---- residues generated adiabatic compression of air .
10 main oil seal extrusion heel cracks ; reason ---- pressure, extrusion gap is too large , as when using the support ring installation groove design is unreasonable.

Autumn to autumn to go, Xiao Meng to tail. Whispering this side, the heart is resting deep thoughts disintegrated, the fog seemed to fall into. Negative security seals killed trace black out days into the heavy round pace off over black out, the original go by is a fog. All quiet scary little cry, and some just flat day to tone. Like in the West Bank under the foam seals, floating like Gu Ming, quietly a hit, but it broke.Bolt seal
This was authentic, you can speak without thinking about the need to weep. Going through grief, sorrow speed, twists and turns and so on. . . The situation too, was eventually buried under the dust of past night. Its really painful, speed worries, just as cloudy, rainy, like alternation. Why should correct solution where tears fall sky.
Container seals wire seals plastic seals & n bsp; Meiko off over the side of the black day, sit dawn sky. Breathe as one old Ying space, riding death dawn, outside the circle before, people still stick to their suspicious death of a dream negative thinking, heroic lines into.Cable tie
