Description

Novel single cylinder high pressure diving pump

Technical field

The utility model relates to a kind of novel single cylinder high pressure diving pump.

Background technique

Submersible pump is claimed Submerged Motor Pumps again, english name submersible pump.Submersible pump is a kind of broad-spectrum water treatment instrument, no matter is the shadow that in agricultural production or industrial processes, can both see submersible pump.Can be divided into submerged pump, sand-discharging submerged pump, clear water submersible pump substantially by its application and purposes.

Submersible pump generally is made up of the pump housing, lifting pipe, pump seat, submersible motor and starting guard equipment.Popular saying is exactly the machinery of the conveying liquid that unites two into one of a kind of pump and motor, and it is simple in structure, and is easy to use.

Submersible pump development has had the history in more than 60 year, the Bu Long of the U.S. in 1904 so far. and first has successfully designed, has made the Submerged Motor Pumps and the submersible motor of horizontal connection Jackson (Byron Jackson) company, the ancestors of Here it is modern Submerged Motor Pumps.Along with the development of materials science, sealing technique, control and resist technology and the raising of cold and hot working technological level, Submerged Motor Pumps has obtained develop rapidly.Nineteen twenty-eight, direct-connected vertical Submerged Motor Pumps was invented by the said firm, and this is the original form of modern deep-well Submerged Motor Pumps.

China began to produce the work surface Submerged Motor Pumps of 7KW in 1958 by Renmin Motor Factory, Shanghai, had opened the prelude that China's Submerged Motor Pumps is produced, and through 30 years of development, had obtained bigger achievement at present.

Different with the relative position of motor according to pump, submersible pump can be divided into pump formula and down-pump type again.Last pump formula submersible pump pump in the above, motor below, this structure has reduced the radial dimension of pump greatly, so be used for well with Submerged Motor Pumps and small-scale workshops Submerged Motor Pumps more.The down-pump type motor for submerged pump in the above, pump below, it is divided into two kinds of built-in type and external mounteds again.In the liquid carried of dress down-pump type Submerged Motor Pumps at first through surrounding the ring runner of motor, make it behind the cooling motor again efflux pump and extrude mouthful.Even this pump needn't worry that also motor heats up, so application area enlarges day by day near draining under the situation of priming reservoir.Outer dress down-pump type Submerged Motor Pumps is direct pumping chamber or the diffuser outlet port drain behind the impeller then, the liquid cooling that motor is also pumped.Because the down-pump type structure can also can be worked in more shallow liquid, so be usually used in the work surface Submerged Motor Pumps, especially it is the main structure pattern of heavy caliber Submerged Motor Pumps.The mechanical seal of down-pump type Submerged Motor Pumps is positioned at outlet current zone of high pressure, and lift is high more, and water pressure is high more here, so the performance of mechanical seal receives the control of lift.

Submersible pump is according to the difference of its blade wheel structure characteristics, and the application is just different.Open type or half-opened impeller: the abrasive-resistant material manufacturing, with adjustable stator and filter screen.Be widely used in plumbing such as building site, grotto, bay, factory, naval vessel or water injection etc., can pump and contain liquid mediums such as abrasive material such as clay, sand, rubble, drilling cuttings etc.Portable structure is put in the water and just can starts, and can satisfy specific (special) requirements such as big flow, high-lift, the confined space or explosive environments.Do not have the enclosed of obstruction flow channel type impeller, have good reliability and higher efficient, be mainly used in city pumping plant and sewage treatment works and pump sewage and mud, pumps cooled water, waste water, Korrosionsmedium etc. in the industrial flow, building site and integrated mill's continuous drainage etc.Be fit to very much pump the medium that contains long stapled material and big solid particle.Be installed in small-sized and simple pumping plant, can conceal and be located at undergroundly, pump can be installed on guide rail or the rope and down to the pump hole fast and simply.Unshrouded impeller also has S type cutter, have pump, cutting and mixed function.Good reliability, efficient is high.Be mainly used in and pump the liquid excrement on the agricultural, can the broken solid of doing, straw and other long fibre material, spiral helicine impeller eye can make the stiff muck of suction send in the pump, has four kinds of specifications.Compact structure is installed on the guide rail in the muck pond, also can be installed in the storage pool, can be used with submersible agitator.The multiple-blade double shrouded wheel, cylinder iron or stainless steel casting, one-sided or bilateral (double suction) water inlet.Be particularly suitable for agricultural sprinkling irrigation and various commercial Application, as supplying clear water, technological process water, injection and cooling water etc.Can satisfy high-lift big flow needs, flow reaches 2000m3/h, and lift reaches 110m, is suitable for pumping the water of clear water or slight pollution, and plurality of specifications and structural type are arranged.Function is strong, and reliability is high, easy mounting and maintenance.

The adjustable vane aial flow impeller has energy-efficient characteristics.Be mainly used in agricultural, urban water supply and sewerage and industry and go up pumps cooled water etc., and can be used for controlling the inland waterways system.Can satisfy the special requirement of low lift and large flow rate, be suitable for pumping the water of clear water or slight pollution.

But, now because drought and water shortage causes submersible pump to be not suitable for the need of work of plateau, arid, water-deficient area.
