Generally, the pressure bladder material of circulating pump is neoprene, model MY Dwg H71128/1/2 (Wartsila
Propulsion Singapore Pte Ltd are produced), possess good elasticity.For above-mentioned pressure bladder, bonding agent is excellent
Select 6025 glue (CHCMOSIL X6025).
After bonding agent is smeared, 40min or so is spontaneously dried.
In addition, before step S1, being cleaned to the interface of the butt end 101,102 of pressure bladder 100, it is ensured that interface
Cleannes.
S2, by the support 30 on two butt ends 101 of pressure bladder 100,102 abutting joints to base 10, and will
Pressure bladder 100 is pressed on base 10.
Wherein, the inner circumferential shape of the shape correspondence pressure bladder 100 of support 30 is set so that support 30 can coincide twelve Earthly Branches
Support is in the lower section of pressure bladder 100；The length of support 30 is consistent with the length of base 10, or the slightly smaller than length of base 10.It is close
Envelope air bag 100 is pressed on base 10, it is impossible to have rake angle phenomenon.
The pressure bladder inner circumferential of circulating pump is generally T-shaped, so as to form the inner passage of pressure bladder；The correspondence of support 30
For T-shaped support.
S3, gland 20 is pressed on pressure bladder 100, and be locked on base 10.
Wherein, two butt ends 101,102 of pressure bladder 100 position the positioning being contained between gland 20 and base 10
In groove 40, support 30 is supported on the lower section of pressure bladder 100.
Further, base 10 may include first base 11, be mobily connected in the second base of the one end of first base 11
12；Gland 20 includes coordinating the first gland 21 in first base 11 and end gland 23, coordinated in second base 12
Second gland 22, end gland 23 is located at side of first gland 21 away from the second gland 22.Second base 12 can pass through regulation
Component 13 is connected to one end of first base 11, and passes through the adjustable distance between the two of adjusting part 13.Adjusting part
13 include screw bolt and nut for being engaged etc..
Step S3 may include following steps：

After step S3.2, the distance between second base 12 and first base 11 are adjusted so that pressure bladder 100
Two butt ends 101,102 closed butt joints, there is certain thrust.The distance between second base 12 and first base 11 are adjusted
Section, can be realized by rotating the nut of adjusting part 13.
In addition, to prevent relative slip between the gland 22 of pressure bladder 100 and second, the pressing of the second gland 22
Before, the fine sandpaper of increase frictional force is placed on pressure bladder 100；After the pressing of second gland 22, fine sandpaper is located at pressure bladder
100 and second between gland 22.Before placement, by fine sandpaper doubling, the pressure of pressure bladder 100 and second is placed on coarse face outwardly
Between lid 22, increase frictional force.
S3.3, the first gland 21 pressed on pressure bladder 100, and be locked in first base 11.
First gland 21 is compressed 100 two butt ends of pressure bladder 101,102, and thrust should not in compaction process
Excessive, composition surface should be without gap between the first gland 21 and first base 11.Lock of first gland 21 in first base 11
Tightly, it can be realized by latch assembly, such as bolt.
In step S3.3, to ensure interface bonding quality, before the pressing of the first gland 21, in pressure bladder 100 two
The interface spreading glue of butt end 101,102.It further can also stick high temperature adhesive plaster.
S4, base 10 and/or gland 20 are heated, pressure bladder 100 is heated and vulcanized, makes two of pressure bladder 100
The interface of butt end 101,102 bonds together, and forms the pressure bladder 100 of overall ring-type.
During heating, in the bottoming hole that heating rod (not shown) is plugged into the gland 21 of first base 11 and first respectively.Two
The setting of individual bottoming hole, is heated simultaneously, it is to avoid single hole heats brought temperature gradient explained, improves the uniformity of heating.
Correspondence heating rod, the temperature that temp probe (not shown) is plugged into the gland 21 of first base 11 and first respectively is visited
In gaging hole, with detection temperature.
On the gland 21 of first base 11 or first, the distance between bottoming hole and temperature sensing hole and bottoming hole and positioning
Vertical range between the inner top surface of groove 40 (pressure bladder upper surface) is of substantially equal, improves the accuracy of measurement temperature.Preferably,
The distance between bottoming hole and temperature sensing hole are slightly more than bottoming hole and the inner top surface of locating slot 40 (upper surface of pressure bladder 100)
Between vertical range.
Specifically, step S4 may include following steps：
S4.1, it is heated to after 45-55 DEG C, constant temperature 5-10min；It is preferred that 50 DEG C, constant temperature 5min.
S4.2, it is heated to after 95-105 DEG C, constant temperature 5-10min；It is preferred that 100 DEG C, constant temperature 5min.
S4.3, it is heated to after 150-160 DEG C, constant temperature 25-30min；It is preferred that 150 DEG C, constant temperature 30min.The speed of heating should
Suitably so that be heated to 150 DEG C of 1 hour or so used times.
Step S4 can be realized by heater.Heating rod is powered, while monitoring temperature variations.
