Description
Technical field
The utility model is a kind of device applying the pressurization of Submerged Motor Pumps raising municipal water supply pipeline.
Background technique
The working principle of normal Submerged Motor Pumps drives submersible pump impeller to rotate by the running of submersible motor, accumulated step by step transferred out by meson by impeller and blower inlet casing.General Submerged Motor Pumps is applied to Deep Underground water intaking or wet pit draining, and mounting type is vertical.Although the necessary vertical installation of Submerged Motor Pumps, Applicable scope is very restricted, but be still widely used in municipal water supply, cause with the defect solved due to the aging of pipe network or design the problem that a lot of area is not enough at water use peak phase pressure of supply water, make a big impact to civil plantation.Submerged Motor Pumps was because necessary vertical installation in the past, in the pressurization of water supply network uses, need build many pump houses and arrange many supervision and attendant, water supply company haves no alternative but arrange pressurization station in many areas, the pressure-raising of pipeline is realized by increasing pipeline compression pump, particularly urban building is built higher and higher, adds operation cost to water undertaking.
Summary of the invention
The purpose of this utility model is to provide a kind of submersible pump unit for pipeline pressurization, is connected in supply channel, does not need pump house and personnel to safeguard, saves a large amount of man power and material, water supply pressure-raising cost is low, Be very effective.
This submersible pump unit for pipeline pressurization, comprise submersible motor, submersible pump, after it is characterized in that submersible pump to be connected with submersible motor output terminal is horizontal, be placed in the outer cover of cartridge type, pump cover, outer cover and pump cover are fastened as a whole by connection part, pump cover end is connected with reducer by source nipple by pump cover flange, forms the working space of water-filling; The reducer the other end is through Flange joint water pipe; The outer cover of motor bottom is also connected with water end (W.E.) on water pipe.
This submersible pump unit for pipeline pressurization of the present utility model, is applied in pipeline and adds and press, in order to solve the problem that water supply line tail forces down by submersible pump.Its technology brings following advantage:
1, reasonable in design, structure is simple, and low cost of manufacture, for user saves a large amount of pump house capital investments and maintenance operation cost.
2, installation, maintenance is simple, basically identical with normal pipeline installation procedure, need not increase erection unit.
3, the physical features of using area, angle limits is not subject to, can level, inclination or vertically install, expand the Applicable scope of submersible pump.
4, improve quality of water supply and efficiency.
Accompanying drawing explanation
Fig. 1 is the submersible pump unit structural representation for pipeline pressurization of the design.
Embodiment
For the submersible pump unit of pipeline pressurization, comprise submersible motor 1, submersible pump 4, it is characterized in that submersible motor 1 to be placed in the outer cover 2 of cartridge type, submersible pump 4 is placed in pump cover, after submersible pump 4 is connected with submersible motor 1 output terminal, outer cover 2 and pump cover 5 are fastened as a whole by connection part 3, pump cover 5 end is connected with reducer 8 by source nipple 7 by pump cover flange 6, forms the working space of water-filling; Reducer 8 the other end is through Flange joint water pipe; By flange outer cover 2 be connected with water end (W.E.) on water pipe bottom submersible motor 1 and seal.Pump cover flange 6 also has cable seal interface 9, after the cable of submersible motor 1 is drawn thus, by bolt, nut fixing seal gland and stuffing box gland.
Outer cover 2, pump cover 5 are tubulose, and caliber is identical, and inner tube wall all has projection, are the supporting point of submersible motor 1.There are outer ring flange and screw in the two ends of outer cover 2 and one end of pump cover 5, and the other end of pump cover 5 has edge in path.Source nipple 7 is isometrical straight tube, and the equal diameters of reducer 8 one end diameter and source nipple 7, the other end is corresponding with flange.Described connection part 3 all has packing ring, pad, nut, bolt, and the same with described flange is standard piece, according to installation requirement, selects different size, and has corresponding waterproof measure.
The working principle of this device is connected on municipal network water supply by submersible pump by a tubular device, forms an assembly unit in this tubular device by straight tube, source nipple, reducer, pump cover flange and sealing, connection part.In installation process, without the need to building pump house, only pressurization place need be needed on water supply network to repair a heavy pond, the space of actual just this device of accommodation, be hidden in subsurface, by this element by the Flange joint at two ends on the pipeline of water supply network, can vertically, level, loxosis, not affecting by installing physical features, on heavy pond, spreading lid or plant lawn.And the regulator cubicle of a connection pump cable is installed near at hand, can remote supervisory be realized by the control of microcomputer, hold without the need to there being people and keep.
