Abstract
The utility model relates to the technical field of a mechanical engineering pump, which is applicable to a dry submersible electric pump with the rated operational voltage of 380 volts. The utility model is characterized in that an oil chamber 6 and a leakage cushion seal chamber 2 are arranged between a blade wheel 1 and other components 8 of an electric motor. A blade guide body (or a seal housing) 4 is a supporting body of a bearing 5, and mechanical seal bases 13 and 14. The mechanical seal 10, 12 and 15 are respectively responsible for the shaft end sealing action between the oil chamber 6 and the inner chamber body 7 of the electric motor, between the oil chamber 6 and the leakage cushion seal chamber 2, and between the leakage cushion seal chamber 2 and the outside world. Through the probation of the utility model, the failure-free operation time and the dependability of the pump are remarkably improved.
Description
The utility model relates to mechanical engineering pump class technical field, is applied to rated operational voltage and is 380 volts dry-type submersible pump.
Submerged Motor Pumps is the incorporate product of pump and submersible electric motor, and the motor of dry-type submersible pump seals fully, in case in the outer liquid inflow motor of pump, cause motor to damage.On the projecting shaft of this dry diving motor, mechanical seal is housed, a closed chamber is arranged between pump impeller and motor, want lubricating oil filling (perhaps other Lubricants) in this closed chamber, so also be referred to as the grease chamber.The dry diving motor of or specific (special) requirements high-power for some is often also being adorned bearing in the grease chamber, in case and grease chamber's water inlet will soon jeopardize the bearing in motor and the grease chamber, the reliability of Submerged Motor Pumps is affected.
The purpose of this utility model provides a kind of dry-type submersible pump that leaks the cushion seal chamber that increases between pump impeller and grease chamber, improve the reliability of dry-type submersible pump.
This reality is made novel purpose and is achieved in that
That is: pump impeller 1 is installed on the motor reel 3, between pump impeller 1 and other assembly 8 of motor a grease chamber 6 is arranged, and also has one to leak cushion seal chamber 2, and the volume that leaks cushion seal chamber 2 is greater than 30cm
3For high-power or the dry diving motor of specific (special) requirements is arranged, bearing 5 is housed in grease chamber 6; Diffuser (perhaps seal casinghousing) 4 promptly is the supporting mass of bearing 5, also is the supporting mass of mechanical sealing base 13,14. Mechanical seal 10,12,15 is being undertaken grease chamber 6 and motor inner chamber body 7 respectively, is being leaked the shaft end seal effect between cushion seal chamber 2 and grease chamber 6 and the leakage cushion seal chamber 2 and the external world, so extraneous liquid will be earlier leaks enter through mechanical seal 15 at axle head and leaks cushion seal chamber 2, is full of just to enter grease chamber 6 after leaking cushion seal chamber 2.With improve before compare, the utility model is many one leak cushion seal chamber 2, improved the reliability of pump.
Concrete structure of the present utility model is provided by the following drawings and embodiment.
Fig. 1 is the utility model complete machine structure schematic representation.
As shown in Figure 1, this novel dry-type submersible pump is made up of impeller 1, leakage cushion seal chamber 2, motor reel 3, diffuser (perhaps seal casinghousing) 4, bearing 5, grease chamber 6, motor inner chamber body 7, other assembly 8 of motor, mechanical sealing base 9, mechanical seal 10, ring washer 11, mechanical seal 12, mechanical sealing base 13, mechanical sealing base 14, mechanical seal 15, influent base 16, impeller nut 17.
It is characterized in that: between impeller 1 and other assembly 8 of motor, grease chamber 6 is arranged, leak cushion seal chamber 2 in addition, diffuser (perhaps seal casinghousing) the 4th, bearing 5, mechanical sealing base 12 and 15 supporting mass.
The utility model has the advantages that: extraneous liquid will enter to leak through mechanical seal 15 earlier at axle head and delay Rush closed chamber 2, be full of leakage cushion seal chamber 2 and just can enter grease chamber 6 later. Owing to leak cushion seal The buffering retardation of chamber 2 has delayed extraneous liquid and has entered grease chamber 6 and motor inner chamber body 7 by axle head Time, motor and bearing 5 have been played protective effect, improved the reliability of this pump. This new knot Structure is through on probation, and significantly improve the non-failure operation time of pump, is subjected to the welcome at family on probation.
Claims (3)
1. novel dry-type submersible pump, it by impeller 1, leak cushion seal chamber 2, motor reel 3, diffuser (perhaps seal casinghousing) 4, bearing 5, grease chamber 6, motor inner chamber body 7, other assembly 8 of motor, mechanical sealing base 9, mechanical seal 10, ring washer 11, mechanical seal 12, mechanical sealing base 13, mechanical sealing base 14, mechanical seal 15, influent base 16, impeller nut 17 and form.It is characterized in that: the rated operational voltage of this pump is 380 volts; Impeller 1 is installed on the motor reel 3, between impeller 1 and other assembly 8 of motor grease chamber 6 is arranged, and leaks cushion seal chamber 2 in addition; The shaft end seal effect between grease chamber 6 and motor inner chamber body 7, grease chamber 6 and leakage cushion seal chamber 2 and the leakage cushion seal chamber 2 and the external world is being undertaken in mechanical seal 10,12,15 respectively.
2. novel dry-type submersible pump according to claim 1 is characterized in that: high-power or the dry-type submersible pump of specific (special) requirements is arranged for some, bearing 5 is housed in grease chamber 6; Diffuser (perhaps seal casinghousing) the 4th, bearing 5, mechanical sealing base 13 and 14 supporting mass.
3. novel dry-type submersible pump according to claim 1 is characterized in that: the volume that leaks cushion seal 2 is greater than 30cm
