Background technology
Pendular ring type self priming pump has the pendular ring wheel with pump shaft linkage, is made up of pendular ring room, gas-liquid separation chamber, pump, motor, gas
Liquid separation chamber top is air chamber, and bottom is fluid reservoir, and air chamber is provided with blast pipe, and fluid reservoir is provided with what is connected with pendular ring room
Return duct, the air in inlet pipeline is first discharged pump chamber, air discharge outlet, liquid together with liquid by pendular ring wheel during work
Body is back in pendular ring room, and self-suction function is realized in constantly circulation.Traditional pendular ring self priming pump, enter normal work after the completion of self-priming
When, pendular ring wheel still follows pump shaft to rotate, and mechanical loss be present, and return duct reflux medium produces larger internal leakage, and efficiency is low.
The content of the invention
The purpose of this utility model is the shortcomings that presence for prior art, there is provided a kind of efficient Pendular ring type is sucked away from certainly
Heart pump.
The technical solution of the utility model includes motor, the pump housing, impeller, pump shaft, pump inlet cavity, pacifies in pump inlet cavity
Fill pendular ring room, pendular ring indoor location pendular ring wheel installs gas-liquid separation chamber on the pump housing, pendular ring room pass through conduit with gas-liquid separation chamber
Portion is connected, and gas-liquid separation chamber is connected with pump housing outlet cavity, and gas-liquid separation chamber bottom is connected by return duct with pump inlet cavity；
Connected mainly between the rotating shaft of pendular ring wheel and pump shaft using clutch, check-valves is set on return duct, check-valves is by valve body, bullet
Spring and ball sealer composition, spring one end are arranged on the body cavity of pump inlet cavity side, and the other end contacts with ball sealer, in place
The sealing surface to be cooperated with ball sealer is formed with the middle part of the spring on the body cavity wall in outside.
In above technical scheme, clutch uses hydraulic clutch, and the hydraulic control room of hydraulic clutch passes through impulse
Pipe connects with gas-liquid separation chamber.
The utility model has the advantages that being connected between the rotating shaft of pendular ring wheel and pump shaft using clutch, set on return duct
Check-valves, when pump self-priming completes normal work, clutch departs from, and pendular ring wheel stops the rotation, and reduces mechanical loss, while liquid storage
Closure of check ring, prevention pump discharge medium are flowed back and produce internal leakage by chamber pressure rise from return duct, have both solved traditional self-priming
The problem of centrifugal pump self-priming time is long, solve the problems, such as that pendular ring efficiency of centrifugal pump is low again, its suction lift reaches 5 meters, self-priming
Time is less than 40 seconds, and efficiency reaches more than 70%.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
1 motor, 2 impellers, 3 valve bodies, 4 pump housings, 5 springs, 6 return ducts, 7 fixed seats, 8 pump shafts, 9 clutches, 10 rotating shafts, 11
Pendular ring pump cover, 12 pendular ring wheels, 13 pressure guiding pipes, 14 pump inlet cavitys, 15 conduits.
Embodiment
Pendular ring type self-priming centrifugal pump as shown in Figure 1, including motor 1, the pump housing 4, impeller 2, pump shaft 8, pump inlet cavity 14,
Pendular ring room is set in pump inlet cavity 14, pendular ring indoor location pendular ring wheel 12, gas-liquid separation chamber is installed on the pump housing 4, pendular ring room leads to
Cross conduit 15 to connect with gas-liquid separation chamber, the one end of conduit 15 connection pendular ring pump cover 11, other end connection gas-liquid separation chamber top, gas
Liquid separation chamber exports cavity with the pump housing 4 and connected, and gas-liquid separation chamber bottom is connected by return duct 6 with pump inlet cavity 14, pendular ring
During the rotation of wheel 12, gas-liquid mixed media is sucked in pendular ring room from pump inlet cavity 14, and gas-liquid separation is sent into by conduit 15
Interior, gas-liquid separation chamber's upper gas are discharged by being exported from the pump housing 4, and gas-liquid separation chamber's lower liquid is flowed back by return duct 6
Pump inlet cavity 14；Connected using clutch 9 between the rotating shaft 10 of pendular ring wheel 12 and pump shaft 8, inhaled from pumping phases, clutch 9
Close, when self-priming terminates to enter normal work, clutch 9 separates, and pendular ring wheel 12 stops the rotation, and reduces mechanical loss；On return duct 6
Check-valves is set, and check-valves is made up of valve body 3, spring 5 and ball sealer, and the one end of spring 5 is arranged on the side of pump inlet cavity 14
The inner chamber of valve body 3, the other end contact with ball sealer, are formed with and ball sealer phase on the internal chamber wall of valve body 3 on the outside of the middle part of spring 5
The sealing surface mutually coordinated, during self-priming state, fluid pressure is less than the elastic force of spring 5 in gas-liquid separation room, and check-valves is in and opened
State is opened, liquid is back in pump inlet cavity 14 by return duct 6；When self-priming terminates to enter normal work, gas-liquid separation chamber
Interior pressure rise, when the pressure difference between gas-liquid separation chamber and pump inlet cavity 14 reaches the setting value of spring 5, check-valves closes
Close, prevent liquid backflow in gas-liquid separation room, it is therefore prevented that the internal leakage of return duct 6, when solving existing self-priming centrifugal pump self-priming
Between it is long low with Pendular ring type efficiency of centrifugal pump the problem of, its suction lift reaches five meters, and self-priming time is less than 40 seconds, and efficiency reaches
More than 70%.Check-valves can also other structures form.
Clutch 9 uses hydraulic clutch, and the hydraulic control room of hydraulic clutch passes through pressure guiding pipe 13 and gas-liquid separation chamber
Connection, clutch body are fixedly mounted in pump inlet cavity 14 by fixed seat 7.From liquid pressure in pumping phases, gas-liquid separation room
Power very little, the adhesive of clutch 9；When self-priming terminates to enter normal work, fluid pressure increase, the fluid pressure in gas-liquid separation room
Enter the hydraulic control room of hydraulic clutch by pressure guiding pipe 13, separate clutch 9, pendular ring wheel 12 stops the rotation.
