Abstract
The invention relates to a submersible motor pump, which belongs to the technical field of pump pipeline pressurization and water supply mechatronic equipment, in particular to a novel double-suction high-efficiency submersible motor pump. The novel double-suction high-efficiency submersible motor pump is characterized by comprising a pump body 1, an impeller 2, a pump cover 3, an isolated oil chamber group 4, a pump shaft rotor group 5, a motor stator group 6, a hung cover 7, a hung cover sealing plate 8, a cable component 9, a water leakage protection component 10, a mechanical sealing piece 11, an oil chamber cover plate 12, an oil seal 13, a pump cover O-shaped sealing ring 14, a water outlet 15, a water inlet A 16 and a water outlet B 17. The novel double-suction high-efficiency submersible motor pump is an ingenious combination of a submersible motor and a double-suction pump and therefore has both the functions of a submersible motor pump and the special high-efficiency and stable performance of the double-suction pump. As a unique double-suction flow channel structure is adopted, water enters from the two ends of the impeller 2 of the pump at the same time and flows out from the middle in the actual operation of the pump. The water inlets (16 and 17) of the pump are two parts arranged up and down, water are introduced from the bottoms of the water inlets, and the water suction level in water suction direction is low. As water is sucked from upper and low two ends, the pump and one end of the isolated oil chambers 4 of the motor 6 are positioned at the position of the water suction openings and operate under a negative pressure all the time. Thus, compared with a pump with a single-suction structure, the pump is more insusceptible to water leakage. The motor pump sucks water from the upper and lower ends at the same time, so the motor 6 withstands no axial tensile force; in addition, the double flow channel structure further reduces a radial force.
Description
Technical field
The present invention relates to Submerged Motor Pumps, water pump pipeline supercharging, the electrical integrated equipment technical field of feeding engine, the efficient Submerged Motor Pumps of especially a kind of novel double-sucking type.
Technical background
The immediate like product of the present invention is sewage dirt Submerged Motor Pumps, proof submersible sand discharging pump, clear water Submerged Motor Pumps, all belongs to single suction formula Submerged Motor Pumps.Because of it belongs to single suction formula structure, so there is following shortcoming:
1, owing to be monolateral suction from impeller, and consequent axial centrifugal tension is bigger, and heavy caliber, big flow, high-lift model is obviously bigger than normal, thereby causes the very fast damage of pump shaft of motor, and working life is shorter.
2, owing to belong to single suction formula structure, its motor part is isolated by the grease chamber, and one side of grease chamber is in the pump chamber, water pump is in operation, and pump is in always pressure state, and high-lift pressure is high more, because of generally all adopting double mechanical seal, Submerged Motor Pumps does the axle envelope, fuel tank is in always pressure condition, so very easily leak (high-lift pump is easy more to leak), thereby cause motor water inlet, damage.
3, also having the immediate like product of a kind of the invention is double-sucking type double volute Submerged Motor Pumps, and it is the upper water-out structure, suction water level height, and complex structure, extremely unreasonable and uneconomical, with this product in essence difference is arranged.
Summary of the invention
The present invention is a kind of novel double-sucking type Submerged Motor Pumps; be characterised in that and comprise: 1 pump housing, 2 impellers, 3 pump covers 4 are isolated grease chamber's group 5 pump shaft rotor set 6 motor stator groups 7 and are hung and cover 8 and hang and cover sealing plate 9 cable assembly 10 and leak and protect assembly 11 mechanical sealing elements 12 grease chamber's cover plates 13 oil sealings 14 pump cover O RunddichtringOs 15 water outlets; 16 water inlet A, 17 water inlet B.
The invention belongs to the ingenious combination of submersible motor and double-sucking type pump, make its function that not only has Submerged Motor Pumps, have the property that double suction pump efficiently operates steadily again.This pump divides clear water and sewage two big series, is divided into plain edition and band outer circulation cooling water type simultaneously in this two big series again and stirs evenly the type three major types automatically.
Double-sucking type Submerged Motor Pumps of the present invention belongs to a kind of pump product of brand new, has filled up international, domestic this structure historical blank, and the axial tension that has thoroughly solved single suction formula Submerged Motor Pumps is big, the shortcoming of using mechanical seal easily to leak in more high-lift occasion.Low, simple and practical because of suction position, it is high also to have solved other similar double-sucking type Submerged Motor Pumps suction position, complex structure, shortcoming such as uneconomical.
Because of the limit water outlet of ripe single suction formula Submerged Motor Pumps relatively of employing technology, the flange mounting structure promptly can adopt to move and install, and also can adopt the guide rail fixed installation. and installation and maintenance are easy to use.
Because of adopting unique double-sucking type double flow channel structure, water pump is in actual motion, and water is that the two ends from water pump vane 2 intake middle the outflow simultaneously.The water intake of water pump (16,17) divides two-part up and down, and all from the bottom diversion, suction direction suction position is low.Because from two ends suction up and down, so isolation grease chamber 4 one ends of pump and motor 6 are in the position, water sucking mouth, the negative pressure state that always is in service, relative single suction formula structure antileaking, because of pump is to absorb water simultaneously from two ends up and down, therefore motor 6 has not had axial tension, and the double flow channel structure has alleviated radial force especially, thereby its prolonged in working life, reached the function of the durability of using, stability, practicability.
The invention has the beneficial effects as follows: 1. the present invention can low water level operation, and the suction water level is low high-lift, energy-efficient.2. adopt two hydrating structures down, motor 6 has not had axial tension, alleviate and balance radial force, improved pump efficiency.3. improved the working life of pump greatly.4. more reasonable structure, compactness are aesthetic in appearance, make the pump operation safety and reliability.
