Abstract
The present invention provides the device that a kind of Submerged Motor Pumps can be connected and be used in the deep-well single conduit.Submerged Motor Pumps is supported and fixed in the shell by the connecting tube at shell two ends with calmly, the connecting tube middle part of bearing pulling force has tie-plate to be connected with shell, the upper end picks out water pipe, the outlet pipe of termination bottom Submerged Motor Pumps is connected with the Submerged Motor Pumps formation in the shell under the shell, on the drainage mesh of pump sucking pipe is installed, be provided with cable sealing device on tie-plate, all connect all sealings.
Because to bear pulling force strong for this device, fixedly submersible pump device and seal arrangement arranged reliably and to the automatic suction means of high spatial in the shell, thereby guaranteed Submerged Motor Pumps series operation in the deep-well single conduit.
Description
The invention belongs to Submerged Motor Pumps and be used for increasing the device of lift water lift in deep-well series connection.
Mostly existing Submerged Motor Pumps 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, in order to address this problem, many series connection with two above pumps, the needs of lift have been guaranteed so effectively, but used device adopts the mode of connecting with another Submerged Motor Pumps again after Submerged Motor Pumps and pipeline parallel connection or the two pumps parallel connection more, thereby needs bigger hole diameter, so it is just inapplicable that the hole diameter of Submerged Motor Pumps well-digging generally is installed routinely.
Task of the present invention is in order to overcome the deficiency of above-mentioned tandem arrangement, a kind of device of the water lift of connecting with another Submerged Motor Pumps in the single conduit of deep-well to be provided.
Design main points of the present invention are: this tandem arrangement is installed in the big reducing position at deep-well; This device is because each connected element can holder all parts of bottom and the weight of water and the pulling force of inner pipe water pressure, so can be in deep-well and the use of connecting in single conduit of another Submerged Motor Pumps; This device two ends that are fixed as to Submerged Motor Pumps in shell (3) are fixed; Submerged Motor Pumps outlet pipe under this device is the intake pipe of this device, water enters under the effect of bottom Submerged Motor Pumps in the shell (3) of this device, enter Submerged Motor Pumps (4) then, because each connects all sealings to shell (3) up and down, and the automatic suction means of high-order space air in pair shell arranged, start the Submerged Motor Pumps (4) in this device, promptly reach the purpose of the raising lift water lift of connect with another Submerged Motor Pumps.
With reference to Fig. 1, this device is made up of cable seal (2), shell (3), Submerged Motor Pumps (4), fixed middle (6), connecting tube (7), the sucking pipe (11) etc. of supporting.The connecting tube (7) [comprising tie-plate (9)] of welding or casting can be straight tube shape or gradually stretches tubular, the tie-plate (9) at this pipe middle part and the shell (3) that manage in the garden or the garden that is approximately is tubular are with flange or be threaded, upper end and outlet pipe are with flange or be threaded, the lower end is connected with the water outlet (10) of Submerged Motor Pumps (4), and connection set is pressed the pump type can be with screw thread or flange.Connecting tube (7) has the strength bar (8) of welding or being cast into one with tie-plate (9), to strengthen bottom all wt and the pipe internal pressure flexural stress to this dish.The tie-plate (9) of connecting tube (7) and this pipe bears the weight of all parts of bottom and water and the pressure in the pipe, and the weight and the pump internal pressure of water in water pump and the pump only born in connecting tube (7) lower end.Support (6) in fixed and be connected shell (3) lower end, and be connected with bottom Submerged Motor Pumps outlet pipe, connection set can be with flange or screw thread.Above-mentioned all connections all seal with sealing material.Be provided with cable seal (2) device on tie-plate (9), the cable (1) of Submerged Motor Pumps (4) is drawn by this device.With reference to Fig. 2, 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 (1) closely cooperate, in case shell (3) outside air enters or internal water spills.
With reference to Fig. 3 and Fig. 5, support in fixed (6) device by centring sleeve (17) or centring sleeve (25), decide medium-height trestle (18), locking nut (19), fixed middle screw rod (20) and form.It is taper that centring sleeve (17) internal diameter of osculum (21) and water inlet (22) is arranged, and also can change the centring sleeve that external diameter is a taper (25), the cone match of the conical surface and Submerged Motor Pumps (4) motor base (5) into according to the structure of submersible electric pump motor; There is the medium-height trestle (18) of deciding of water inlet (23) to be fastened on shell (3) lower end; The sphere of screw rod (20) upper end for protruding in fixed, the recessed sphere of this face and centring sleeve (17) joins and cooperates, because this screw rod and to decide medium-height trestle (18) be screw-thread fit, tighten this screw rod promptly firmly Submerged Motor Pumps (4) motor side is supported fixed in the centre of shell (3), use locking nut (19) locking then.With reference to Fig. 1 and Fig. 4, one end of garden shape sucking pipe (11) stretches in the water strainer (12) of Submerged Motor Pumps (4) or makes groove (24) shape and is connected with the mesh of water strainer (12), the pump housing of the other end of pipe and Submerged Motor Pumps (4) is fixed, the mouth of pipe stretches to the high spatial in the shell (3), the negative pressure of utilizing water strainer (12) to locate will collect in the air suction pump of shell (3) internal upper part and discharge.
The present invention is strong owing to each connection part bears pulling force, seal arrangement is reliable, reliably fixing device flexibly of pair Submerged Motor Pumps (4) is arranged, external diameter is little to the hole diameter influence, and be provided with automatic suction means to the interior high spatial air of shell (3), thereby possessed the condition that in the deep-well single conduit, can connect, made Submerged Motor Pumps (4) work in shell (3) normally, obtained increasing the effect of lift water lift with another Submerged Motor Pumps.
The present invention and the repacking of finished product Submerged Motor Pumps are supporting, promptly become deep-well series connection Submerged Motor Pumps.
