Description
Technical field
The present invention relates to the magnetically-actuated pipe type centrifugal pump of the plurality of installation forms such as vertical sleeping suspention, be a kind of the suitableeest
In the production procedure in the fields such as chemical industry, oil, refinery, pharmacy, alkaline, antacid, printing and dyeing, food, conveying is without solid
Grain, proportion are not more than the cleaning liquid of 1.84, be particularly well-suited to inflammable, explosive, poisonous, be harmful to, have the valuable liquid of caustic to be situated between
The conveying of matter.
Background technology
The pipeline pump that the fields such as current chemical industry, oil, refinery, pharmacy, alkaline, antacid, printing and dyeing, food are used is vertical
Being arranged on pipeline, its seal style can use mechanical seal pattern and two kinds of patterns of magnetically-actuated static seal, and the type pump has
Some features: pump is vertical structure, turnover bore is identical, and is positioned on same centrage, can be directly installed on as valve
Among pipeline, compact appearance is attractive in appearance, and floor space is little, and building puts into low, adds that protective cover is placed in outdoor use.
The most domestic produced mechanical seal pipeline pump and magnetically-actuated pipe type centrifugal pump have the following disadvantages:
1. the seal style of mechanical seal pipeline pump uses mechanical seal, and this is sealed into movable sealing pattern, exists easy to wear
Rupture and lost efficacy, the defect such as pumped (conveying) medium easily leaks, sealing life is short, if pumped (conveying) medium is inflammable, explosive, poisonous, harmful, machine
The leakage that tool bad seals produces can make environment heavily contaminated, can cause fire, blast, personal injury and great time serious
Property loss.
2. part magnetically-actuated pipe type centrifugal pump uses and uses the mode being mounted directly, this peace between pump shaft and axle sleeve
Dress mode can be very accurate to Element Design dimensional requirement, and its requirement on machining accuracy also can be the highest, if otherwise transport pump medium temperature
Time higher or lower can because of phenomenon of expanding with heat and contract with cold be easy to occur stuck turn motionless, so that pump can not run well, time serious
Package unit can be caused to stop.
3. part magnetically-actuated pipe type centrifugal pump uses and uses " O " RunddichtringO swelling to install between pump shaft and axle sleeve
Mode, this mounting means can be the highest to the requirement of " O " RunddichtringO material, and quality of fit requires the highest, should consider " O "
The decay resistance of RunddichtringO and wear-corrosion resistance, it is also contemplated that the high temperature resistant and low temperature resistant performance of " O " RunddichtringO, no
Then pump can run by normal table, and fault rate can be the highest, and maintenance cost can be the biggest.
4. also have magnetically-actuated pipe type centrifugal pump use pump shaft directly install with sliding bearing contact formed revolving part and
The mounting means of static element friction pair, this mounting means can be very accurate to Element Design dimensional requirement, its requirement on machining accuracy
Also can be the highest, difficulty of processing can be very big, and pump otherwise can be caused because of phenomenon of expanding with heat and contract with cold when pumped (conveying) medium temperature is higher or lower
Be easy to occur stuck turn motionless, also result in pump shaft or axle sleeve, sliding bearing abrasion the most even crack damage, so that pump
Can not run well, package unit time serious, can be caused to stop.
5. the installation approach of pump only has the vertical of pump or two kinds of installation approach of horizontal type according to the requirement that pipeline is arranged.
The sliding bearing of the most existing magnetically-actuated pipe type centrifugal pump is to be directly loadable in pump cover or bearing holder (housing, cover), bearing block, once
Sliding bearing damages necessary integral replacing, and therefore the assembling of the sliding bearing of the type pump, maintenance are understood very inconvenient, and maintenance expense
The highest with meeting.
