Abstract
The present invention provides a device for submersible pumps to be connected in series in submersible pumps in single pipelines of deep wells. Submersible pumps are fixed in a casing by a connecting pipe and a fixed middle support on both ends of the casing, a connecting tray is arranged in the middle of the connecting pipe for bearing tension to be connected with the casing, a water outlet pipe is connected with the upper end of the connecting pipe, the water outlet pipe connected with the lower submersible pump at the lower end of the casing and the submersible pumps in the casing are connected in series, an air suction pipe is installed on a water strainer of the pump, a cable sealing device is arranged on the connecting tray, and all connections are sealed. Because the device bears strong tension and is provided with a device capable of reliably fixing a submersible pump device and a sealing device and automatically sucking air from high space in the casing, the serial connection work of the submersible pumps in single pipelines of deep wells is ensured.
Description
The invention belongs to submersible pump and be used for increasing the device of lift water lift in deep-well series connection.
Mostly existing submersible pump is that separate unit uses at the vertical installation water lift of deep-well, owing to be subjected to the influence of water level of deep well, a pump does not often satisfy the needs of lift, and lift needs more, the also corresponding increase of the lifting pipe of submersible pump, and the problem of being brought is safe lifting.In order to address this problem, U.S. US3726610 patent disclosure a kind of erecting device of submersible pump, the safety lifting that has solved many lifting pipes of deep-well, this device does not satisfy the needs of submersible pump series connection use lift.The mounting and positioning device of the submersible pump of Germany DE3710452A1 patent disclosure, be applicable to the series connection of deep well submerged pump, this device fixedly is to adopt elasticity support claw fixation method to the submersible pump bottom in shell, pipeline has water hammer or vibrations, because of the support claw resiliently deformable, can influence the stability of submersible pump upper end sealability and submersible pump.
The objective of the invention is in order to overcome the deficiency of said apparatus, a kind of connect with another submersible pump device of usefulness of submersible pump that rigidly fixes in the deep-well single conduit is provided.
Submersible pump series connection of the present invention comprises with device: submersible pump (6), it places in the shell (7), the upper end is connected with the lower end of connecting tube (10), shell (7) upper end is connected with the tie-plate (8) at connecting tube (10) middle part, the lower end with decide medium-height trestle (3) and be connected, with decide medium-height trestle (3) screw-thread fit fixed in screw rod (1) cooperates with the centring sleeve (5) that is matched with submersible pump (6) lower end and joins, calmly in screw rod (1) hold out against submersible pump (6) lower end fixing.
Below in conjunction with embodiment shown in the drawings, describe the present invention in detail.Wherein:
Fig. 1 is the device sectional view of submersible pump series connection usefulness of the present invention;
Fig. 2 is the cable sealing device sectional view.
Referring to accompanying drawing 1, the device of submersible pump of the present invention series connection usefulness is by submersible pump (6), decide medium-height trestle (3), fixed middle screw rod (1), locking nut (2), centring sleeve (5), shell (7), connecting tube (10), cable seal (12) etc. and form.Submersible pump (6) places in the shell (7), and shell (7) can be pipe or approximate pipe.The connecting tube (10) [comprising tie-plate (8)] of welding or casting can be straight tube or gradually stretches tubularly, and the upper end of lower end and submersible pump (6) is with the flange or the location that is threaded, and shell (7) is connected with screw thread or flange with the tie-plate (8) at middle part.Connecting tube (10) has the strength bar (9) that is connected as a single entity with tie-plate (8), to strengthen the intensity of tie-plate (8).The tie-plate (8) of connecting tube (10) and this pipe bears the pulling force of pipeline, and the connection screw thread of connecting tube (10) lower end or flange only bear the weight and the pump internal pressure of water in submersible pump (6) and the pump.
Submersible pump (6) lower end is fixed by support device in fixed, and this device is formed by decide medium-height trestle (3), fixed middle screw rod (1), centring sleeve (5), locking nut (2).The lower end that medium-height trestle (3) is fastened on shell (7) of deciding that water inlet (4) is arranged, the middle part has and its fixed middle screw rod (1) with threads engaged, the join centring sleeve (5) that cooperates of this bar and submersible pump (6) lower end cooperates and joins, the connecting part is that concavo-convex sphere cooperates, centring sleeve (5) is a cone match with the connecting part of submersible pump (6) lower end, screw rod (1) promptly firmly holds out against the lower end of submersible pump (6) and is fixed in the middle of the shell (7) in tightening surely, uses locking nut (2) locking then.
Fig. 2 is the sectional view of cable seal (12) device, and this device is welded on the tie-plate (8) of connecting tube (10), and the cable of submersible pump (6) is drawn by it.This device is made up of gland (13), sealing seat (14), packing ring (15), seal ring (16).By press gland (13) with screw thread or screw rod, make packing ring (15) compress seal ring (16), this circle pressurized and cable (11) closely cooperate, and prevent that promptly shell (7) outside air from entering or internal water spills.
This device is connected in the pipeline, the upper end is water outlet, the lower end is water inlet, water enters under the effect of bottom submersible pump in the shell (7) of this device, enters submersible pump (6) then, because each connects all sealings, the rigid fixation means that pair submersible pump (6) are arranged, reliable and stable, start the submersible pump (6) in this device, promptly reach the purpose of the increase lift water lift of connect with another submersible pump.
The present invention and the repacking of finished product submersible pump are supporting, promptly become deep-well series connection submersible pump.
Claims (2)
1, the device of submersible pump series connection usefulness, by submersible pump (6), shell (7), connecting tube (10), decide medium-height trestle (3), screw rod (1) in fixed, centring sleeve (5), cable seal (12) is formed, it is characterized in that placing submersible pump (6) upper end in the shell (7) to be connected with the lower end of connecting tube (10), shell (7) is connected with the tie-plate (8) at connecting tube (10) middle part, the medium-height trestle (3) of deciding that has water inlet (4) is connected with shell (7) lower end, with decide medium-height trestle (3) screw-thread fit fixed in screw rod (1) cooperates with the centring sleeve (5) that is matched with submersible pump (6) lower end and joins, calmly in screw rod (1) hold out against submersible pump (6) lower end fixing.
2, device according to claim 1 is characterized in that middle surely screw rod (1) is concavo-convex sphere with the connecting part that cooperates of centring sleeve (5).
