Abstract
The present invention provides a kind of Submerged Motor Pumps and is used for the device of pressurized water supply in piping erection.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 shell lower end taps into water pipe, be provided with manual and automatic air eliminator inside and outside the shell, be provided with cable sealing device on tie-plate, all connect all sealings.
Because to bear pulling force strong for this device, the automatic and manual means of deflation of high spatial in the fixedly submersible pump device and seal arrangement and shell is arranged reliably, thereby guaranteed that Submerged Motor Pumps normally works in shell, obtain effect at the piping erection pressurized water supply.
Description
The invention belongs to Submerged Motor Pumps installs in water supply line and is used for the device of pressurized water supply.
The existing exposed pipeline mounted pump device of pipe pressurizing water supply installation multipurpose motor, reached the purpose of pipe pressurizing, but this pump type is at high temperature season electric machine temperature rise height, influence continuous supercharging work, efficient is low, hour flow does not have to surpass the specification of two hectosteres, what have uses in pipeline with Submerged Motor Pumps, though obtained the effect of supercharging, but in shell, the fixing of Submerged Motor Pumps mostly adopted jackscrew and slip fixation method, jackscrew seal complex, fixed middle poor performance, slip fixation method instability has influenced the extensive use of Submerged Motor Pumps at pipeline.
The objective of the invention is provides a kind of Submerged Motor Pumps to install in pipeline in order to overcome the deficiency of above-mentioned supercharging device, not only is suitable for small flow, and is used for surpassing the pressurized watering device of hour flow two hectosteres.
Design main points of the present invention mainly are: this device is applicable to that the Submerged Motor Pumps of small-large flow is used for pipe pressurizing and supplies water; This device is fixed the two ends that are fixed as of Submerged Motor Pumps (5) in shell (4); It is big that this installs each connected element bearing capacity, reliable to the fixing device of Submerged Motor Pumps (5), can be by the requirement of water supply line, and upright, crouch and insert in the pipeline; This device is connected in the pipeline, the upper end is water outlet, the lower end is water inlet, water in intake pipe enters the tubular shell (4) of this device, enters Submerged Motor Pumps (5) then under the pressure of system pipeline, because each connects all sealings shell (4), and the automatic and manual means of deflation of high-order space air in pair shell is arranged, and start the Submerged Motor Pumps (5) in this device, promptly reach the purpose of water supply line pressurized water supply.
With reference to Fig. 1, this device is made up of cable seal (2), shell (4), Submerged Motor Pumps (5), fixed middle (7), connecting tube (8), the sucking pipe (13) etc. of supporting.Shell (4) can be garden pipe or is similar to the garden pipe and ellipse garden pipe, square tube or multi-angular tubular.The connecting tube (8) [comprising tie-plate (3)] of welding or casting can be straight tube or gradually stretches tubular, the tie-plate (3) at this pipe middle part and shell (4) 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 (12) of Submerged Motor Pumps (5), and connection set is pressed the pump type can be with screw thread or flange.Connecting tube (8) has the strength bar (9) that is connected as a single entity with tie-plate (3), to strengthen the flexural stress of pipe tension to tie-plate (3).The tie-plate (3) of connecting tube (8) and this pipe bears the pulling force of pipeline, and the connection screw thread of connecting tube (8) lower end or flange only bear the weight and the pump internal pressure of water in Submerged Motor Pumps (5) and the pump.Support (7) in fixed and be connected shell (4) lower end, and be connected with the pipeline water 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 (3), the cable (1) of Submerged Motor Pumps (5) is drawn by this device.With reference to Fig. 2, this device is made up of gland (15), sealing seat (16), packing ring (17), seal ring (18), by press gland (15) with screw thread or screw rod, make packing ring (17) compress seal ring (18), this circle pressurized and cable (1) closely cooperate, in case shell (4) outside air enters or internal water spills.With reference to Fig. 3 and Fig. 5, support in fixed (7) device by centring sleeve (19) or centring sleeve (27), decide medium-height trestle (20), locking nut (21), fixed middle screw rod (22) and form.It is taper that centring sleeve (19) internal diameter of osculum (23) and water inlet (24) is arranged, and also can change the centring sleeve that external diameter is a taper (27), the cone match of the conical surface and Submerged Motor Pumps (5) motor base (6) into according to the structure of submersible electric pump motor; The lower end that medium-height trestle (20) is fastened on shell (4) of deciding that water inlet (25) is arranged; The sphere of screw rod (22) top for protruding in fixed, the recessed sphere of this face and centring sleeve (19) joins and cooperates, because this bar and to decide medium-height trestle (20) be screw-thread fit, tighten this bar promptly firmly the motor of Submerged Motor Pumps (5) is supported fixed in the middle of shell (4), use locking nut (21) locking then.With reference to Fig. 1 and Fig. 4, in order to emit the gas collection of the interior high spatial of shell (4), be provided with vent hole (10) and (11) at tie-plate (3) and shell (4), two holes respectively connect the venting valve or according to this device upright, installation situation crouches, one hole plug, another hole connects valve, emits gas collection before the turn on pump earlier and starts Submerged Motor Pumps (5) again.Be in operation, for collection air of high spatial in shell (4) is in time discharged, in shell (4), be provided with sucking pipe (13), one end of this pipe stretches in the water strainer (14) of Submerged Motor Pumps (5) or makes groove (26) shape and is connected with the mesh of water strainer (14), the pump housing of the other end of pipe and Submerged Motor Pumps (5) is fixed, the mouth of pipe stretches to the high spatial in the shell (4), the negative pressure of utilizing water strainer (14) to locate will collect in the air suction pump of shell (4) internal upper part and discharge.
The present invention since each connection part to bear pulling force strong, seal arrangement is reliable, reliably fixing device flexibly of pair Submerged Motor Pumps (5) is arranged, and be provided with to the interior high spatial air of shell (4) manually and automatic air eliminator, can make Submerged Motor Pumps (5) work in shell (4) normally, reach the purpose that is used for pressurized water supply in piping erection.
As long as the present invention promptly becomes the submerged pipe pump that is used for pressurized water supply in piping erection supporting with the repacking of finished product Submerged Motor Pumps.
