The installation in portion 3.At this point, the axle center of the second straight pin 5 and the axle center of pump case 1 are arranged in a mutually vertical manner.
Thermal shock operating condition can occur in pump group work, at this time at the driving end of pump case 1, due to the of the first support portion 2
One straight pin 4 is parallel to the axis direction of pump case 1, and the first straight pin 4 and corresponding connection bolt 7 are to be not subject to shearing force
, the connection bolt 7 that can be prevented the first straight pin 4 and fix the first straight pin 4 fails.In the anti-drive end of pump case 1, pump
The two sides of shell 1 be provided with second straight pin 5 vertical with 1 axis direction of pump case bear thermal expansion generate shearing force, due to
Straight pin is made of stainless steel material and 7 diameter of bolt is bigger, and therefore, the second straight pin 5 can be born more compared to connecting
Big shearing force effectively plays the supporting role of the second support portion 3.
In order to preferably play the effect that the second support portion 3 resists shearing force, the support for enhancing 1 anti-drive end of pump case is strong
Degree, the second support portion 3 further includes support plate 33, which is located at the top of two second bases 31, and passes through bolt
Structure fixing clamp is set between the second support sole 321 and second base side plate 312, and support plate 33 passes through another second cylinder
Pin 5 is fixedly connected on the lower section of pump case 1.The middle part of support plate 33 is equipped with pin hole, correspondingly, on the lower sides of pump case 1
Offer another pin hole.When it is implemented, first 5 a part of the second straight pin is inserted into the pin hole of 1 lower sides of pump case, it is another
In the pin hole of partial insertion support plate 33, then support plate 33 fastened by gasket 8 and several connection bolts 7 and pump case 1.Work as pump
Shell 1 occur thermal shock when, three directions of the anti-drive end of pump case 1 are equipped with the second straight pin 5, can fully bear by
In the shearing force that thermal expansion generates, the normal operation of pump group can be protected, can also guarantee the service life of support construction.
In order to enhance being fixedly connected for support plate 33 and second base 31 and the second support leg 32, sole is supported second
It 321, can be with from top to bottom through being inserted with one or more fixed pin 34 on support plate 33 and second base side plate 312
The overall stability for guaranteeing the second support portion 3 is conducive to it and plays supporting role.
Since pump case 1 is generally stainless steel material, and support construction mostly uses carbon steel material to make, when using straight pin into
When the connection of row support construction and pump case 1, carbon steel is directly contacted with pump case 1 and is polluted in order to prevent, in support construction and pump
