Chemical desulfurization pump is industrial production, brick factory power plant desulfurization, sewage circulation and so on pump commonly used in the chemical anti-corrosion pumps, desulphurization water pump
not only anti-corrosion, explosion-proof, wear-resisting, large flow, high lift, etc all kinds of specifications, users in the use of desulphurization pump, pipeline installation of connecting the deviation and shortage, the pipe expansion is a common pipe compensation, pipe connection important equipment, expansion pipe (
Can also be called pipe slip joint, expansion joint, compensator, expansion joint.
Expansion joints is pumps, valves, pipes and other devices connected to the pipeline of new products, connected by the bolt, making it a whole, and has certain displacement, convenient installation.
Can withstand axial stress of pipeline.
So you can at the time of installation and maintenance, according to the on-site installation size adjustment, at work, not only improve the work efficiency, but also for pump, valve, pipeline equipment play a protective role.
The connection form of expansion is a flange connection, flange, one side welding.
A classification according to the structure, scale expansion joints (
Mainly used for compensating pipe expansion deformation caused by temperature change, also used in a pipeline etc need to install the length of the compensation, mainly divides into the form of the structure bend type expansion joint and bellows expansion joint and three kinds of casing slip.
1, casing expansion joints by the axial relative movement of the inner and outer casing can be [
Casing slip joint]
USES the stuffing box seal between inner and outer casing.
Keep on both ends of the pipe when used in a moving axis.
On both ends of the slip joint installed guide bracket.
It has the advantage of small friction resistance to the flow of fluid, the structure is compact;
Defect is poor sealing, thrust to the fixed support is bigger.
Casing expansion joints and low pressure steam pipeline is mainly used for water pipes.
2, pipe bend type expansion joint [a u-shaped bend or other form
Bend type expansion joint]
And use the form of compensation for the elastic deformation of the expansion joint.
It has the advantage of good intensity, long service life, can be made at the scene, the disadvantage is that take up the space is big, the consumption of steel and frictional resistance to this expansion joint is widely used in all kinds of steam pipe and long pipe.
3, bellows expansion joint with a kind of metal corrugated tube expansion joint.
It can slip along axis direction, and allow a small amount of bending.
Bellows expansion joint]
For common axial type bellows expansion joint, axial length compensation in the pipeline.
In order to prevent more than allow the amount of compensation, on both ends of corrugated pipe has protective bars or protection ring, in connection with it at both ends of the pipeline set on the guide bracket.
Another corner type and the horizontal type expansion joint, can be used to compensate Angle deformation and lateral deformation of the pipeline.
The advantage of this kind of expansion joint is save space, save material, easy standardization and mass production, the disadvantage is that life is short.
Bellows expansion joint are used for temperature and pressure is not high, shorter length of the line.
With the improvement of corrugated pipe production technology level, this kind of expansion joint application scope is expanding.
By work constitute the main body of corrugated pipe (
A kind of elastic element)
Tubes, stents, and end of flange, pipe and other accessories.
Mainly USES in all kinds of pipe, it can compensate the pipe thermal displacement, mechanical deformation and absorb all kinds of mechanical vibration, it could reduce the pipeline deformation stress and enhance the role of the service life of the pipeline.
Corrugated compensator connection mode can be divided into flange connections and welding two kinds.
Welding methods commonly used directly buried pipeline compensator.
Second, the expansion pipe according to material classification according to material consists of expansion pipe and metal pipe expansion rubber pipes.
Metal pipe expansion characteristic: the expansion of large amount of compensation, under high temperature and under high pressure.
Rubber pipe expansion characteristics: 1, small volume, light weight, good elasticity, easy installation and maintenance.
2, the installation time can produce axial, lateral, warp, angular displacement, not restricted by user pipe different heart, flange unparallel.
3, work can damping noise reduction.
4, with special synthetic rubber can be high temperature resistant, acid and alkali resistant, oil resistant, chemical corrosion resistance pipe is the ideal product.
Three, telescopic unit 1.
Compensating absorption pipeline axial, lateral and angular heat expansion caused deformation.
Vibration absorption equipment, reduce the influence of equipment vibration on pipeline.
Absorb the earthquake, subsidence deformation of pipeline.
Because of the pipe heat bilges cold shrink, so for pipeline, will produce the wall stress and tension;
Wall stress, which affect the strength of the pipeline, push pull, will do a lot of pipe fixed bracket, telescopic pipe produced by push pull;
So using the slip joint compensation amount of variable drive way, in order to reduce the wall stress and thrust.
