Abstract
The utility model discloses a centrifugal water pump bottomless valve draining device, which relates to the technical field of water pump draining devices and is provided with a water sump connected with a water sucking bucket by the aid of a pipeline. The water sucking bucket is connected with a water inlet pipe of a water pump by the aid of a water sucking pipe; a drinking water valve is mounted on the water sucking pipe; a check valve and a stop valve are sequentially mounted on the water inlet pipe of the water pump; the bottom of the water sucking bucket is connected with the water pump by the aid of a connecting pipe; the upper end face of the water sucking bucket is provided with an exhaust pipe; and an exhaust valve is mounted on the exhaust pipe. The centrifugal water pump bottomless valve draining device has the advantages of simplicity in manufacture and installation, stability in operation and convenience in maintenance.
Description
Technical field
The utility model relates to water pump drainage means technical field, specifically is a kind of Centrifugal water pump without bottom valve drainage means.
Background technique
As everyone knows, Centrifugal water pump operation in down-hole, mine be unable to do without three valves (check valve, stop valve, bottom valve), and is especially high especially to the requirement of bottom valve, should bear certain pressure, also good sealing will be arranged, rate of fault is very high in actual use, and when maintenance difficulty relatively.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the utility model provides a kind of Centrifugal water pump without bottom valve drainage means, need not bottom valve, good airproof performance.
The utility model is realized with following technological scheme: a kind of Centrifugal water pump without bottom valve drainage means, comprise drinking-water valve, check valve, stop valve, water pump and sump, and check valve and stop valve are installed on the intake pipe of water pump in proper order; Sump is connected with draw buket by pipeline; Draw buket is connected with the intake pipe of water pump by aqueduct, and the drinking-water valve is installed on this aqueduct; The bottom of draw buket is connected with water pump by connecting tube; The upper-end surface of draw buket is equipped with outlet pipe, and outlet valve is installed on the outlet pipe.
The beneficial effects of the utility model are: this device is made, installs simple, stable, easy to maintenance.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is the utility model schematic representation.
Among the figure: 1, draw buket, 2, outlet valve, 3, the drinking-water valve, 4, check valve, 5, stop valve, 6, water pump, 7, sump.
Embodiment
As shown in drawings, Centrifugal water pump without bottom valve drainage means has a sump 7, sump 7 is connected with draw buket 1 by pipeline, draw buket 1 is connected by the intake pipe of aqueduct with water pump 6, drinking-water valve 3 is installed on this aqueduct, order is installed check valve 4 and stop valve 5 on the intake pipe, and stop valve 5 is near water pump.The bottom of draw buket 1 is connected with water pump 6 by connecting tube; The upper-end surface of draw buket 1 is equipped with outlet pipe, and outlet valve 2 is installed on the outlet pipe.All valves on this device all adopt ball valve; The bottom end of draw buket 1 is near the sump liquid level.
In the fabrication and installation process: bucket high and the bucket of (1) draw buket are directly than being generally 1.25～1.5; General 4～10mm the steel plate that adopts of draw buket is made, and gets big value when the bucket footpath is big, hour gets the small value.
(2) volume of draw buket and be generally 3～4 to the ratio of the piping volume between the draw buket more than the sump liquid level.
(3) the intake pipe caliber that requires of aqueduct caliber water intaking pump, the connection mouth of two pipes and draw buket should be not on one side.
(4) draw buket is established an end-of-the-pipe in addition, sewage draining exit is connected with water pump by pipeline, connecting tube should be tried one's best near the bucket bottom, draw buket should place near the sump absorbing well, absorption well when installing, and should try one's best at the bottom of its barrel near the sump liquid level, and pump outlet should not be higher than draw buket, connecting tube can obliquely be installed, water pump and draw buket distance should not surpass 5m, and the aqueduct total height should not surpass 6m, can establish filter screen at the subsurface diversion mouth of pipe in case of necessity.
(5) diversion valve can use other water sources, as using submersible pump or storehouse water diversion etc.
The specific operation step:
Open pump: (1) is opened the diversion valve water filling and is gone into draw buket, and during to the outlet valve spilling water, inner bucket water is full;
(2) close outlet valve, diversion valve after, draw buket only is connected with sump and water pump;
(3) start water pump, earlier inner bucket water is pumped, after the inner bucket water position descends, form negative pressure, barometric pressure is gone into draw buket with hydraulic pressure in the sump.
Termination of pumping: (1) closes stop valve;
(2) termination of pumping.
Should notice that in use all can not there be leakage phenomenon in outlet valve, diversion valve, cylindrical shell.
Effect contrast: since the horizontal pump house of the plumbous zinc ore+100m of Pakistani Du Da uses, rate of fault is almost nil, improved the utilization efficiency of water pump, and reduced the consumption of filler, reduced the amount of maintenance of water pump, guaranteed drainage underground work, for the smooth construction of project engineering has been created advantage.
Claims (4)
1. a Centrifugal water pump without bottom valve drainage means comprises drinking-water valve (3), check valve (4), stop valve (5), water pump (6) and sump (7); Check valve (4) and stop valve (5) order are installed on the intake pipe of water pump (6); It is characterized in that: sump (7) is connected with draw buket (1) by pipeline; Draw buket (1) is connected by the intake pipe of aqueduct with water pump (6), and drinking-water valve (3) is installed on this aqueduct; The bottom of draw buket (1) is connected by connecting tube and water pump (6); The upper-end surface of draw buket (1) is equipped with outlet pipe, and outlet valve (2) is installed on the outlet pipe.
