axis for the original packing seal slurry pumps for sale , change the mechanical seal according to various considerations for different types of structures, such as high temperature slurry, to consider the mechanical seal face cooling, negative pressure slurry pumps for sale inlet, tight mechanical seal to be considered (i.e. the sealing surface of the open end with a groove, through the pressure inside the water); cover tablets such as liquid containing impurities, but also consider the use of clean soiled liquid backwash. 

    mechanical seal structure in which a stationary ring packing box with a pin fixed ring rotates with the shaft. ring and stationary ring end face contact with a seal To prevent other parts of the leak, a secondary seal - rubber ring. ring, stationary ring and the shaft and stuffing box there is sufficient clearance to increase with the stationary ring ring mobility, to ensure good contact. 

    ring, stationary ring material selection is the key to for the transport of water slurry pumps for sale, snap ring with carbide or stainless steel copper surfacing wear, static ring with cut graphite impregnated Sleeve (or impregnated bronze) for transporting turbine oil slurry pumps for saleing, in addition to the above materials, the ring can be applied to 3Cr13 stainless steel or 45 gauge steel, stationary ring using bronze turbine oil lubrication performance is very good, so the material requirements can reduce the number. 

    retrofit mechanical seal, if the stuffing box small radial size, can not affect the strength of the case the sleeve small car, or to fill box to expand, while the axial dimension generally outwardly projecting part 

    of the mechanical seal slurry pumps for sales in power plants using very successful, while the original braided asbestos packing, by the sub loose texture sparse, there are gaps between the porous, can not be avoided outward permeability addition, the slurry pumps for sale end of the shaft seal can be canceled in order to prevent temperature rise of the bearing, the tubing should be located so that the oil flow cycle, (a) the structure, the use of tubing to make higher-pressure oil into the bearing, in (b) structure, the use of discharge pipe, the use of positive action of the spiral boost oil circulation. 

    mechanical seal during installation should be very carefully polished dynamic and static ring sealing surface to ensure good contact, in order to Seals are lubricated cooling, end back week also opened a gap of several barrier to liquid into the seal faces in order to ring flexible movement, the auxiliary sealing gasket is not too tight on the shaft, and the shaft or sleeve should have high surface finish (generally for Λ8). 

    slurry pumps for sale mechanical seal installed, is not allowed in the axial movement of more than + -0.5 mm   Slurry straight axis, the shaft on the hardwood (or pad with copper leather square iron), concave side up, then use a hammer, twist stick beat, the concave surface of the shaft material by banging and the extensions, the slurry pumps for sale shaft alignment. twist rods are generally made with a hard Ke, its lower end curved surface to be consistent with the shaft, aimed at twisting does not damage the axial plane hit also be used as a twisted rods with brass rods. beat time to start bending the biggest place to start, by playing in the range of one-third of the circumference one can draw a good advance on the shaft. third arc center frequency to be more play, the more the number of times to play both sides of the more less. Initially straight faster, slower later in the course of playing twist To measure the shaft bending timely changes, not fought head 

    bearing material is softer than the twist stick, and to a large contact surface with the shaft, if not so - that strut hard, with rail contact surfaces and small, then the equal punch face twisted together to play, easy-axis alignment. 

shaft after bending will cause the rotor imbalance and movement part of the wear and tear, in the overhaul must be carried on the shaft axis bending measurements. 

    measurement method is: both ends of the shaft iron frame in the V-, V-shaped iron properly put firmly. then dial gauge support, the table point rod axis. then slowly move the shaft site, in the case where the bending axis, with each revolution of the indicator a maximum reading and a minimum reading, it shows the difference between the two readings slurry pumps for saleing degree of bending. 

    This measurement is actually measuring shaft runout, in the past also called Akira degrees. swaying half shaft is bent. general shaft diameter runout is: intermediate not more than 0.05 mm, the ends not more than 0.02 mm. 

    direct axis in many ways, but for slurry, the scene of the most simple way is to lift straight fight axis method. thus here also only introduce this one.   slurry after bending axis, causing the rotor imbalance and movement part of the wear and tear, in the overhaul must be carried out on the slurry pumps for sale shaft bending axis measurements.
