The working principle of said apparatus is: install vibration transducer additional at water pump drive end bearing and/or non-driven-end bearing, detect the Horizontal displacement vibration values of water pump, the Horizontal displacement vibration values of water pump can reflect the attachment situation in stators and rotators gap, if Horizontal displacement vibration values is large, illustrate that the attachment in stators and rotators gap is many, therefore, DCS control system is according to the Horizontal displacement vibration values of water pump, automatically the open degree situation etc. of the branch road modulating valve of respective branch can be regulated, thus regulate the flow of respective branch, reality is cleaned stators and rotators gap attachment, thus denude between reduction parts, the operation period of effective prolongation water pump, realize water pump safety, stable, long-term and safe operation.
Based on above-mentioned principle, according to actual conditions, the flushing pipe quantity that can comprise each flushing unit, the stators and rotators interstitial site of cleaning water pump and vibration transducer are arranged flexibly in the mounting point etc. of water pump, only introduce a kind of concrete example below:
With reference to figure 1, each flushing unit comprises two flushing pipes, is designated as the 1st flushing pipe 1-1 and a 2nd flushing pipe 1-2 respectively; The output terminal of the 1st flushing pipe 1-1 is communicated with the gap between the 1st rotor with the 1st stator of pump outlet; The output terminal of the 2nd flushing pipe 1-2 is communicated with the gap between the 2nd rotor with the 2nd stator of pump entrance end.Pressure gauge 2 and branch road modulating valve 3 is separately installed with at the 1st flushing pipe and the 2nd flushing pipe; Flushing pipe can adopt DN32 Stainless Steel Tube.
With reference to figure 2, for pump outlet reconstruction structure schematic diagram, the outside sheathed jack shaft cover 18 of axle 52 of pump outlet, middle axle sleeve 18 adopts transition fit with axle 52, forms the 1st rotor;
Install middle cover 17 in middle axle sleeve 18 outer gap, in the outer sheathed stationary exit section 16 of middle cover 17, middle cover 17 and outlet section 16 form the 1st stator of water pump;
Offer the 1st through hole 19 at outlet section 16, offer the 2nd through hole 20 in middle cover 17; One end of 1st through hole is communicated with the output terminal of the 1st flushing pipe 1-1; The other end of the 1st through hole is communicated with one end of the 2nd through hole, and the other end of the 2nd through hole is communicated in the 1st gap 21 of the 1st rotor and the formation of the 1st stator.
Therefore, high-pressure washing water can go directly the gap between middle cover 17 and middle axle sleeve 18, effectively rinses rotor and stator gap.
With reference to figure 3, for pump entrance end reconstruction structure schematic diagram, the outside sheathed restrictor sleeve 27 of axle 52 of pump entrance end, restrictor sleeve 27 and axle 52 adopt transition fit, form the 2nd rotor;
Install orifice sleeve 26 in restrictor sleeve 27 outer gap, at the outside sheathed fixing Pyatyi entrance 24 of orifice sleeve 26, orifice sleeve 26 and entrance 24 form the 2nd stator of water pump;
The one end offering the 3rd through hole the 28,3rd through hole 28 of pass-through entry section 24 and orifice sleeve 26 is communicated with the output terminal of the 2nd flushing pipe 1-2; The other end in the 3rd logical 28 holes is communicated in the 2nd gap 29 of the 2nd rotor and the formation of the 2nd stator.
Therefore, high-pressure washing water can go directly the gap between orifice sleeve 26 and restrictor sleeve 27, effectively rinses rotor and stator gap.
With reference to figure 1, two vibration transducers 4 installed by each water pump; A vibration transducer 4 is installed on water pump drive end bearing; Another vibration transducer 4 is installed on non-driven-end bearing.
DSC control system can carry out regulable control based on setting rule to the flow of each flushing pipe:
(1) as Horizontal displacement vibration values≤0.02mm, modulating valve cuts out, rinse water arrangement of stopping using.
(2) as Horizontal displacement vibration values > 0.05mm, equipment alarm (H).
(3) as Horizontal displacement vibration values >=0.08mm, equipment automatic stopping, another pump is from opening.
(4) as 0.02mm≤DCS reveal competence displacement vibration value < 0.08mm, control its flow according to vibration values, vibration values is high, and flow is larger.
Below introduce a kind of embody rule example:
Certain energy company's gasification installation adopts 6 high temperature hot water pumps, model: SCSZ250-100 × 8, flow: 204-250m
3/ h; Lift: 760m; Efficiency: 72%; Operating temperature: 171 DEG C; Medium: buck; Inlet pressure: 0.83MPa; Material: ZG0Cr18Ni12Mo2Ti; Motor: 710KW, net positive suction head: 4m.Only 15 days the shortest working time of this pump, whole unit and disequilibrium, vibration exceeding the standard cannot continue to run.In year February in August, 2010 to 2011, because namely high temperature hot water pump causes system shutdown to reach 4 times.For some time, because pump for car, cannot seriously constrain the stable operation of whole device.
Then, inner local flow improvement is carried out to high temperature hot water pump, and carry out process pipe layout, above-mentioned 5 pumps are made to be linked in water pump rinse-system provided by the invention, by water pump rinse-system, automatically flushing flow value is regulated according to the Vibration Condition of each pump, thus the stators and rotators gap of pump entrance end and outlet end is rinsed, due to the effect of sparge water, buck entrained solid impurity can not enter stators and rotators gap, thus the operation conditions improved between friction member, improve bearing working environment; The temperature of sparge water 104 DEG C is also lower than 171 DEG C of working environment simultaneously, and the incidence rate cavitated is reduced greatly, serves decisive role for solving high temperature hot water pump problem.
Confirm through test, single pump operation reaches more than 60 days, and any exception does not appear in pump; Under high-temperature-hot-water pump discharge is basically stable at 7.36 ~ 7.42MPa situation, stability of flow, at 205m3/h, can meet production normal need completely; If by 60 day operation period, year consumption costs only have (comprising initial stage investment for trnasforming urban land expense 500,000 yuan) 1,500,000 yuan, more than 100 ten thousand yuan can be saved.
In sum, the utility model is by installing Rinsing unit additional to water pump body, stators and rotators gap is effectively rinsed, the solid particle sticking to pump body is rinsed, thus denude between reduction parts, the operation period of effective prolongation water pump, realize the operation that water pump is safe, stable, long-term and safe.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should look protection domain of the present utility model.
