Description

Marine seawater self-priming pump with front-mounted impeller

Technical Field

The utility model relates to a marine water pump technical field, more specifically is a leading marine sea water self priming pump of impeller.

Background

The marine pump is a machine which is used for increasing the pressure or potential energy of liquid and liquid materials on a ship to enable the liquid and the liquid materials to flow. Pumps are generally necessary to deliver liquids to higher locations, distances, and pressures, and can also be used to generate high pressure liquids for hydraulic transmissions. The pump is driven by an electric motor or other prime mover. The marine pump is characterized in that: the pump is required not to generate cavitation due to the fluctuation of the suction liquid level when the ship swings and inclines; in order to reduce the occupied area of the pump and facilitate maintenance, a vertical structure is generally adopted; the through-flow component is made of bronze, brass or stainless steel and the like to reduce corrosion as much as possible.

The impeller pump drives liquid to rotate at high speed by means of an impeller to continuously generate suction and discharge effects, and transmits mechanical energy to the conveyed liquid, so that the pressure of the liquid can be increased, and the purpose of conveying the liquid is achieved. In the limited space of the ship body, the space occupied by the pump body and the efficiency have important influence on the selection of the pump body.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a compact structure, the space occupies for a short time, let out leakage quantity little, efficient leading marine sea water self priming pump of impeller.

In order to achieve the above object, the utility model provides a following technical scheme:

a marine seawater self-priming pump with a front-mounted impeller comprises a pump body part, a water inlet bent pipe, an impeller, a bearing body and a gear shaft;

the water inlet bent pipe is fixedly connected with the pump body part through the pump body connecting assembly to form a liquid flow channel;

the bearing body is fixedly connected with the pump body component through a bearing body connecting assembly;

the impeller is assembled on the gear shaft through an impeller locking assembly;

the gear shaft is assembled with the bearing body through a bearing, and the gear shaft is assembled with the pump body component through a sealing assembly; wherein a portion between the seal assembly and the impeller locking assembly extends into the fluid flow passage.

Further, the impeller is arranged in the water inlet elbow, and the water inlet elbow is directly matched with the impeller.

Furthermore, a self-tightening oil seal is further arranged at the junction of the pump body component and the bearing body and assembled with the gear shaft.

The beneficial effect of this application: in the application, the part between the rotor part sealing assembly and the impeller locking assembly is arranged in the liquid flow channel formed by the water inlet bent pipe and the pump body part, the structure is compact, and the space is saved for the whole pump. Because the water inlet bent pipe is directly matched with the impeller, the gap is small, the impeller is arranged in the water inlet bent pipe in front, the leakage amount is small, and the efficiency is high.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The attached drawing is combined, and the marine seawater self-priming pump with the front-mounted impeller comprises a pump body component 2, a water inlet bent pipe 1, an impeller 3, a bearing body 4 and a gear shaft 6. The water inlet bent pipe 1 is fixedly connected with the pump body part 2 through a pump body connecting assembly 9 to form a liquid flow channel; the bearing body 4 is fixedly connected with the pump body component 2 through a bearing body connecting assembly 5; the impeller 3 is assembled on the gear shaft 6 through an impeller locking assembly 10; the gear shaft 6 is assembled with the bearing body 4 through a bearing 7, and the gear shaft 6 is assembled with the pump body component 2 through a sealing assembly 8. The region between the seal assembly 8 and the impeller lock assembly 10 extends into the fluid flow passage. The impeller 3 is arranged in the water inlet bent pipe 1, and the water inlet bent pipe 1 is directly matched with the impeller 3. And a self-tightening oil seal 11 is also arranged at the junction of the pump body component 2 and the bearing body 4 and assembled with the gear shaft 6.

In the application, the water inlet bent pipe 1 integrates the front guard plate, the front pump cover and the inlet short pipe of the common pump. The number of pump assemblies is reduced. The water inlet bent pipe 1 and the pump body part 2 are connected into a whole through the pump body connecting assembly 9 to form a liquid flow channel, and then the bearing body 4 is connected with the pump body part 2 to form a stator part of the pump. The gear shaft 6, bearing 7, seal assembly 8, impeller 3 and impeller locking assembly 10 form the rotor components of the pump. The part between the rotor part sealing assembly 8 and the impeller locking assembly 10 is arranged in a liquid flow channel formed by the water inlet bent pipe 1 and the pump body part 2, the structure is compact, and the space is saved for the whole pump. Because the water inlet bent pipe 1 is directly matched with the impeller 3, the gap is small, the impeller 3 is arranged in the water inlet bent pipe 1 in front, the leakage amount is small, and the efficiency is high.

In this application, compact structure has reduced the connecting piece, has increased the reliability, has shortened the axial dimensions of pump. Small volume and light weight, and is favorable for use on boats. The gear transmission occupies small space and is convenient to disassemble and assemble. According to the calculation, the space of the ship can be saved by about 6.3 percent; the efficiency is improved by about 5 percent.

It will be apparent to those skilled in the art that while the embodiments of the present invention have been shown and described, there are no difficulties in implementing the functions and features described above, and it is to be understood that various changes, modifications, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents.
