Description
technology neck city:
For a vacuum cylinder for centrifugal water pump, belong to plumbing field of mechanical technique.
background technique:
Centrifugal water pump needs to add water in water pump before operation, requires very tight to the sealability of bottom valve, if any sandstone, slag grass blocking bottom valve; Or intake pipe setting angle is less; Or because of the gas leakage of water pump packing ring; Intake pipe is built-in the reasons such as air, and bottom valve all can be caused to be not closed completely and cannot to fill diversion, and water do not taken out by water pump.
summary of the invention:
To determine the problems referred to above Wei Solution, the utility model designs a kind of vacuum cylinder for centrifugal water pump, and centrifugal water pump draws water not to be needed to install bottom valve, only installs screen cover.
Wei Solution certainly above branch art problem, the utility model provides a kind of Self-priming vacuum cylinder for centrifugal water pump, comprise: water pump spindle, water pump, water pump vane, water pump water outlet flange plate, outlet pipe and flange plate, water feeding of water pump and vacuum cylinder water-output flange dish, diversion funnel, diversion valve, outlet valve, vacuum cylinder intake pipe and flange plate, vacuum cylinder, intake pipe, screen cover; It is characterized in that: 1. the water pump water outlet flange plate described in is connected with outlet pipe and flange plate, water feeding of water pump is connected with vacuum cylinder water-output flange dish, and vacuum cylinder intake pipe and flange plate are connected with intake pipe; 2. the intake pipe front end described in is provided with screen cover, does not install bottom valve; 3. the vacuum cylinder top described in is provided with outlet valve and diversion valve, and diversion valve is arranged on diversion funnel bottom; 4. the vacuum cylinder internal volume described in is 1-1.5 times of intake pipe internal volume; 5. the vacuum cylinder upper and lower end face described in is designed to cambered surface or sphere, for bearing negative pressure; 6. the vacuum cylinder total height described in is 1.5 times of its diameter; 7. the vacuum cylinder inlet tube and outlet tube diameter described in and flange plate identical with pump water inlet diameter and flange plate, two pipes be apart up and down the 1.2-1.5 of water pipe diameter doubly; Pump working front opening diversion valve and outlet valve, a small amount of diversion of annotating in gas-water separating drum and water pump, and close two valves, start water pump, the pumpdown time is generally 1-2 minute, and water pump just can enter normal operation; Water pump is still preserved diversion in water pump and vacuum cylinder after shutting down and can not be descended Lous, does not need diversion of annotating again, starting water pump operation when next time starts pumping for water pump.
What the utility model designed utilizes centrifugal water pump Self-priming vacuum cylinder to vacuumize is because be filled with a small amount of diversion in water pump, water pump vane produces centrifugal force when High Rotation Speed to water, mixing wastewater with air liquid with air is got rid of in outlet pipe, when mixing wastewater with air hydraulic coupling declines, air is discharged from outlet pipe, diversion is not parked in impeller scroll-up/down, now forms negative pressure in vacuum cylinder, and air compressing downstream water enters intake pipe, then enter in vacuum cylinder and water pump, after 1-2 minute, water pump normally runs.
Utilize centrifugal water pump Self-priming vacuum cylinder to vacuumize and have following progress compared with old-fashioned installation bottom valve: 1. owing to being provided with Self-priming vacuum cylinder at water feeding of water pump end, utilize water pump self-suction to vacuumize, do not need bottom valve is installed.2. pump water inlet can stop arbitrarily Fang ， No supplementary condition.3. limit by terrian condition when digging well in mine, the arbitrarily angled placement of steel wire rubber pipe, You Yu No has diversion, moves free and relaxed.4. the serious problems that vacuum cylinder You Xiao Solution has determined because of physics foreign material blocking intake pipe bottom valve and impeller are installed in the Waste Water Treatment in chemical plant and paper mill.5. centrifugal water pump intake pipe bottom valve is because of frequent switch, and rubber valve plate wearing and tearing are very fast, frequent Geng Change, and the self-priming Chou Zhen Kong No of the utility model design has wear-out part, and equipment can Long-Time Service.
In sum, centrifugal water pump Self-priming vacuum cylinder vacuum pumping device You Xiao Solution is utilized to determine centrifugal water pump because bottom valve is not closed completely Wu Fa Jia Full diversion, do not take out the serious problems of water, and can bottom valve be saved, have any supplementary condition to the An Zhuan No of intake pipe, particularly intake pipe uses during steel wire rubber pipe and can lay arbitrarily, as long as have diversion in water pump, start water pump and just can draw up water after 1-2 minute.
Accompanying drawing explanation
Connection with figures is further described the utility model below.
Accompanying drawing is structural representation of the present utility model.
1. water pump spindles, 2. water pump in figure, 3. water pump vane, 4. water pump water outlet flange plate, 5. outlet pipe and flange plate, 6. water feeding of water pump and vacuum cylinder water-output flange dish, 7. diversion funnel, 8. diversion valve, 9. outlet valve, 10. vacuum cylinder intake pipe and flange plate, 11. vacuum cylinders, 12. intake pipes, 13. screen covers.
Embodiment
Connection with figures and embodiment are further described the utility model below.
With reference to accompanying drawing: the water pump water outlet flange plate 4 of water pump 2 is connected with outlet pipe and flange plate 5, the water feeding of water pump of water pump 2 is connected with vacuum cylinder water-output flange dish 6, the top of vacuum cylinder 11 is provided with diversion funnel 7, diversion valve 8 is installed bottom diversion funnel 7, can to annotate in vacuum cylinder 11 and water pump 2 diversion, the top of vacuum cylinder 11 is also provided with outlet valve 9, air-discharging during filling diversion, vacuum cylinder intake pipe and flange plate 10 are connected with intake pipe 12, the front end of intake pipe 12 is provided with screen cover 13, be used for stopping the foreign material blocking intake pipe 12 in downstream water and water pump vane 3.
With reference to accompanying drawing: before water pump 2 first time work, open outlet valve 9 and diversion valve 8, to annotate in diversion funnel 7 a small amount of diversion with bucket or water pipe, close two valves 8,9; Starting motor drives water pump spindle 1 to operate, water pump 2 internal cause is filled with a small amount of diversion, water pump vane 3 produces centrifugal force when High Rotation Speed to water, mixing wastewater with air liquid with air is got rid of in outlet pipe and flange plate 5, diversion is not parked in water pump vane 3 scroll-up/down, when get rid of decline to the mixing wastewater with air hydraulic coupling of outlet pipe and flange plate 5 time air discharge from outlet pipe and flange plate 5, now form negative pressure in vacuum cylinder 11, air compressing downstream water enters intake pipe 12, then enter in vacuum cylinder 11 and water pump 2, after 1-2 minute, water pump 2 enters normal operation; The utility model can be saved time, the Er Qie No that increases work efficiency has easily damaged parts, a lot of troubles when centrifugal water pump uses can be reduced, being particularly suitable for the size centrifugal water pumps such as agricultural drainage and irrigation, paper mill, mine hole well, factory under extreme conditions to use, is a kind of centrifugal water pump optional equipment and new technology that are worthy to be popularized.
