Beneficial effects of the present invention are the dredge pump idle running resistance protection device not only structure letter compared with prior art
It is single, it is at low cost；And it can guarantee three kinds of blocking of the bottom valve in sewage collecting pool, bottom valve leak or liquidometer failure failure feelings
Under condition, dredge pump will not dally.
Detailed description of the invention
Fig. 1 is the structural schematic diagram for the dredge pump idle running resistance protection device that the specific embodiment of the invention provides.
Specific embodiment
To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.
Refering to Figure 1, Fig. 1 is the structure for the dredge pump idle running resistance protection device that the specific embodiment of the invention provides
Schematic diagram.
In the present embodiment, a kind of dredge pump idle running resistance protection device includes sewage collecting pool 1, dredge pump 2 and closed anti-
The tank body of water shortage fluid reservoir 3, anti-water shortage fluid reservoir 3 is made of pvc pipe 30, and the bottom of pvc pipe 30 is fixed by PVC sealing plate 31
It shuts, top is equipped with closing flange 32, and simple easily system is low in cost, and dedicated fluid reservoir in the market can also be used certainly
Or water tank.Screen pack 4 is provided in anti-water shortage fluid reservoir 3, entire fluid reservoir is divided into preceding 33 He of part of filtering by screen pack 4
Part 34 after filtering access water supply pipe 5 and exhaust pipe 6,5 He of water supply pipe on the closing flange 32 at the top of anti-water shortage fluid reservoir 3
Water compensating valve 7 and exhaust valve 8 are separately installed on exhaust pipe 6, the bottom of the preceding part 33 of filtering of anti-water shortage fluid reservoir 3 is provided with row
Blank pipe 9 is provided with blow valve 10 in evacuated tube 9, opens blow valve 10 and periodically carries out thorough cleaning to anti-water shortage fluid reservoir 3, clearly
Anti- water shortage fluid reservoir 3 can be rinsed by water supply pipe 5 when reason.
Dredge pump 2 is connected by the first pipeline 11 with part 34 after the filtering of anti-water shortage fluid reservoir 3, and the first pipeline 11
The second pipeline 12, the other end peace of the second pipeline 12 are accessed in the bottom of part 34 after access filtering, the top for filtering preceding part 33
Dress bottom valve 13 and the bottom for protruding into sewage collecting pool 1, the interior sewage by sewage collecting pool 1 of the second pipeline 12 are sent into anti-water shortage and are stored up
Filter pump web plate 4 is first passed through when flow container 3 and filters out large particulate matter, and dredge pump 2 is avoided to suck large particulate matter.
Be provided in anti-water shortage fluid reservoir 3 with the first liquid level sensor 14, the second liquid level biography is provided in sewage collecting pool 1
Sensor 15, the first liquid level sensor 14 and the second liquid level sensor 15 are communicated to connect with dredge pump 2, and the first liquid level sensor
14 and the equal communication link of the second liquid level sensor 15 be connected to alarm.
It runs for the first time, opens water compensating valve 7, exhaust valve 8, infused by water supply pipe 5 and water compensating valve 7 into anti-water shortage fluid reservoir 3
Water shows in anti-water shortage fluid reservoir 3 and anti-water shortage fluid reservoir 3 to 13 sections of pipelines of bottom valve until there is water spilling in the outlet of exhaust valve 8
Full of water.Stop moisturizing, closes water compensating valve 7, exhaust valve 8.Dredge pump 2 is opened, hereafter can guarantee and operate normally.
When 13 leak of bottom valve in sewage collecting pool 1: the bottom valve 13 out of anti-water shortage fluid reservoir 3 to sewage collecting pool 1
One section of pipeline in water light leakage；Dredge pump 2 is still in operating status at this time, then dredge pump 2 starts to aspirate anti-water shortage fluid reservoir 3
Interior water causes in anti-water shortage fluid reservoir 3 liquid level to decline, and is in negative pressure state in anti-water shortage fluid reservoir 3, in sewage collecting pool 1
Water can still be sucked up to anti-water shortage fluid reservoir 3 by siphonage, and further be taken away by dredge pump 2.Such situation can guarantee
Dredge pump 2 operates normally always, will not termination of pumping, will not dally.
When the bottom valve 13 in sewage collecting pool 1 blocks: dredge pump 2 is still in operating status at this time, then dredge pump 2 starts
The water in anti-water shortage fluid reservoir 3 is aspirated, liquid level in anti-water shortage fluid reservoir 3 is caused to decline, since bottom valve 13 blocks, even if anti-water shortage
Negative pressure in fluid reservoir 3 passes through negative pressure from the water in one section of pipeline of the bottom valve 13 in anti-water shortage fluid reservoir 3 to sewage collecting pool 1
Take out light；And the water in sewage collecting pool 1 cannot be pumped up because of the blocking of bottom valve 13 by siphonage.Anti- water shortage fluid reservoir 3
Interior liquid level continues to decline, until the first liquid level sensor 14 shows low liquid level, alarm, the first liquid level sensor 14 and dredge pump 2
It is dynamic, keep dredge pump 2 out of service.Operator can carry out related maintenance at this time.After the completion of maintenance, by operation operation for the first time, make
Dredge pump 2 is run again.
When the second 15 failure of liquid level sensor: dredge pump 2 will continue to run when low liquid level, cause in sewage collecting pool 1
Water is started to aspirate the water in anti-water shortage fluid reservoir 3 by pumping light, and liquid level is caused in anti-water shortage fluid reservoir 3 to decline, and at this time the
One liquid level sensor 14 is equivalent to second and protects again, and starts to work, when detecting in anti-water shortage fluid reservoir 3 in low liquid level, automatically
Stop dredge pump 2 to run, and alarm, remind operator check bottom valve 13 or the second liquid level sensor 15 with the presence or absence of damage or
Failure carries out related maintenance in time.After the completion of maintenance, by operation operation for the first time, run dredge pump 2 again.
The above embodiments only describe the basic principles and characteristics of the invention, and the invention is not restricted by the above cases,
