Abstract

The utility model relates to a floating electric diving pump, solving the problems of high sealing cost and poor sealing performance on current diving electric pumps. An impeller is arranged on the output shaft of an electromotor of the diving electric pump; an impeller casing is arranged at the outer side of the impeller, with the lower head face provided with a water inlet port at the axial middle and the upper head face provided with an axially arranged water outlet port at one side; and a floater block is arranged at the radial outer side of the impeller casing. The floater block enables the pump body to float on water surface steadily, with only the impeller and the impeller casing submerged in the water. The whole diving pump only has a power line seal and a mechanical seal at the joint of the rotating shaft and the impeller casing, and even if the seals wear down, only a small amount of water flows away along the upper head face of the impeller casing and water will not enter the electric diving pump. Compared with a diving pump in existence, the floating electric diving pump is simple in water proofing structure, low in water proofing cost and better in water proofing effect and is prolonged in maintenance period and improved in service life and safety.

Description

The floating Submerged Motor Pumps

Technical field

The utility model relates to Submerged Motor Pumps.

Background technique

The waterproof technique measure of existing diving electric water pump has three classes, i.e. full-drying type, half dry type and wet type.Full-drying type adopts one to three road single or double mechanical seal to add grease chamber's sealing, with electric elements and bearing and water isolation, shortcoming is to regularly replace Sealing, operation is loaded down with trivial details, the rate of fault height, (how by sealing part abrasion or cable is aging cause) exists electric leakage dangerous to body in case water inlet, and promptly pump case and operation waters are charged, and maintenance cost is also higher.Half dry type is that motor stator seals and rotor impeller rotation in water, and higher with water mill wiping energy consumption in the rotor rotation process, efficient is lower, and the market consumption seldom.Wet type adopts water-fast or oily enameled cable to add and moulds the interplanting stator coil, be full of oil or water in the rotor chamber, bearing adopts engineering plastic bearing or special seal material to come the sealing metal bearing, the same with half dry type, efficient is low in that water or oily transfer kinetic energy consumption is many for rotor, according to record, rotor is directly proportional with five powers of root diameter with the friction of water/oil, for guaranteeing pump efficiency, the pump housing is made slender type more, becomes like this and has limited the unit time water-outlet quantity.The pH value to sand content and water in water temperature, the water of clear water formula all has certain limitation in the wet type, also needs to regularly replace Sealing, silt in the cleaning rotor chamber; The market consumption is also little.At present, market consumption maximum is the full-drying type submersible pump.

Summary of the invention

In order to solve the sealing problem of existing Submerged Motor Pumps, the utility model provides a kind of floating Submerged Motor Pumps.

Concrete architecture advances scheme is as follows:

The floating Submerged Motor Pumps comprises Submerged Motor Pumps, and the output shaft of its motor is provided with impeller, and the impeller outside is provided with impeller chimney, and impeller chimney lower end surface axially middle part is provided with water intake, and impeller chimney upper-end surface one side shaft is to being provided with water outlet, and the impeller chimney radial outside is provided with floating block.

Described floating block is circular, is sleeved on the impeller chimney radial outside.

Floating block of the present utility model can stably swim on the water surface pump housing, have only impeller and impeller chimney not in water, whole Submerged Motor Pumps has only power line sealing, rotating shaft and impeller chimney connecting part that one mechanical seal is arranged, even and sealing wearing and tearing, also have only a small amount of infiltration to pour off, can not enter body along the impeller chimney upper-end surface.Compare with existing Submerged Motor Pumps, waterproof construction is simple, and the waterproof cost reduces, and waterproofing effect improves, and has prolonged the product maintenance cycle, has improved product working life and Safety performance.

Description of drawings

Fig. 1 is the utility model structural representation.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further described by embodiment.

Embodiment:

As seen from Figure 1, the floating Submerged Motor Pumps comprises Submerged Motor Pumps, Submerged Motor Pumps comprises on the output shaft of casing, stator 1, rotor 2, power line sealing 3, impeller chimney mechanical seal 4, its motor impeller 5 is installed, impeller 5 outsides are equipped with impeller chimney 6, impeller chimney 6 lower end surfaces axially middle part are provided with water intake, impeller chimney 6 upper-end surfaces one side is provided with water outlet 7, and impeller chimney 6 radial outsides are equipped with floating block 8.

Floating block 8 is circular, is sleeved on the impeller chimney radial outside.

Floating block 8 can stably swim on the water surface pump housing, has only impeller and impeller chimney not in water, and when drawdown, water pump also can work on along with decline.Whole Submerged Motor Pumps has only two places sealings, i.e. power line sealing 3, rotating shaft have an impeller chimney mechanical seal 4 with the impeller chimney connecting part, and this two place seals and both made wearing and tearing, also has only a small amount of infiltration to pour off along the impeller chimney upper-end surface, can not enter body.

Embodiment 2:

Floating block 8 can be ball float, floating drum etc. also, all is fixedly mounted on the impeller chimney radial outside.

Other is with embodiment 1.
