Description

Technical Field

[0001] The utility model relates to the field of gear pumps, in particular to a gel pumping gear pump. Background Art

[0002] A gear pump is a common hydraulic pump that uses the rotation of motor-driven gears to create vacuum and pressure difference, thereby extracting liquid or liquid mixture from one area and sending it to another area. It usually consists of two or more meshing gears, one of which is driven and the other is driven. The liquid is sucked in and discharged through the gap between the gears, thus completing the liquid delivery process. Gear pumps are commonly used in various industrial and mechanical applications, such as lubrication systems, hydraulic systems, and fuel delivery systems.

[0003] In the prior art, the gear set and the motor are usually an upper and lower structure. When the gear set is driven, due to poor sealing or other reasons, the leakage of the gear set is easy to penetrate into the motor and cause damage to the motor.

[0004] In particular, when this type of upper and lower structured gear pump handles gel-like liquids, the leaked liquid will stick to the motor and eventually cause it to get stuck, seriously affecting the production progress of the production line. Utility Model Content

[0005] The utility model aims to provide a gel pumping gear pump.

[0006] In order to achieve the above purpose, the following technical solutions are adopted:

[0007] A gel pump gear pump comprises a motor, a mounting seat, and a gear assembly. The mounting seat has two mounting grooves on the bottom surface. The motor and the gear assembly are respectively mounted in different mounting grooves. The output shaft of the motor passes through the mounting seat and is exposed on the top surface of the mounting seat. The gear assembly comprises a shell and at least two first gears arranged in the shell, one of the first gears is coaxially connected to a second gear located on the top surface of the mounting seat, the output shaft of the motor is connected to a third gear, and the second gear is connected to the third gear through one or more fourth gears. The water inlet of the shell is located on the bottom surface of the mounting seat, and the water outlet is located on the side of the mounting seat.

[0008] Furthermore, the housing includes an inner housing and a cover body, the inner housing is embedded in the installation groove, has a space for accommodating the first gear, and has a groove for installing the first waterproof ring on its surface, and the cover body covers the installation groove and is in close contact with the inner housing. The split structure of the inner housing and the cover body makes it easy to assemble the first gear, the second gear, etc., and based on the first waterproof ring, the housing can be prevented from leaking to a large extent.

[0009] Furthermore, the water outlet nozzle is integrally formed with the inner shell, and the water inlet nozzle is integrally formed with the cover body.

[0010] Furthermore, a protection rod is provided on the top surface of the mounting seat and above the first gear to prevent the second gear from loosening and causing safety hazards.

[0011] By adopting the above scheme, the beneficial effects of the utility model are:

[0012] The gear assembly and the motor are respectively arranged at both ends of the mounting base, and the water inlet is located at the bottom surface of the mounting base, and the second gear, the third gear, and the fourth gear are located on the top surface of the mounting base. In this way, even if the shell leaks, it will not affect the second gear, the third gear, and the fourth gear, let alone the motor. Therefore, the waterproof effect of the motor is good and the service life is longer. Especially when handling gel liquids, the motor and other gear parts can be effectively protected to prevent the motor from getting stuck. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present invention.

[0018] like Figure 1-2As shown, a gel pump gear pump includes a motor 1, a mounting seat 2, and a gear assembly 3. The bottom surface of the mounting seat 2 has two mounting grooves 21. The motor 1 and the gear assembly 3 are respectively installed in different mounting grooves 21. The output shaft of the motor 1 passes through the mounting seat 2 and is exposed on the top surface of the mounting seat 2. The gear assembly 3 includes a shell and at least two first gears 34 arranged in the shell, one of the first gears 34 is coaxially connected to the second gear 35 located on the top surface of the mounting seat 2, the output shaft of the motor 1 is connected to the third gear 36, and the second gear 35 is connected to the third gear 36 through one or more fourth gears 37. The water inlet 321 of the shell is located on the bottom surface of the mounting seat 2, and the water outlet 312 thereof is located on the side of the mounting seat 2.

[0019] The housing includes an inner housing 31 and a cover 32. The inner housing 31 is embedded in the mounting groove 21, and has a space for accommodating the first gear 34. A groove 311 for installing the first waterproof ring 33 is provided on the surface of the inner housing 31. The cover 32 covers the mounting groove 21 and is in close contact with the inner housing 31. The split structure of the inner housing 31 and the cover 32 makes it easy to assemble the first gear 34, the second gear 35, etc., and based on the first waterproof ring 33, the housing can be prevented from leaking to a large extent.

[0020] The water outlet nozzle 312 is integrally formed with the inner shell 31 , and the water inlet nozzle 321 is integrally formed with the cover body 32 .

[0021] A protection rod 4 is arranged on the top surface of the mounting base 2 and above the first gear 34 to prevent the second gear 35 from loosening and causing potential safety hazards.

[0022] Working principle:

[0023] Generally speaking, the motor 1 of the gear pump is used downward, that is, the water inlet 321 of the shell is facing downward, and the water inlet 321 and the water outlet 312 are respectively connected to the hose. When leakage or water seepage occurs in the shell, or leakage or water seepage occurs between the water inlet 321 and the water outlet 312, since the motor 1 and the gear assembly 3 are arranged in different mounting grooves 21, coupled with the effect of gravity, the liquid will only drip along the hose, which will not affect other gears, let alone the motor 1.

[0024] As can be seen from the above, the gear assembly 3 and the motor 1 are respectively arranged at the two ends of the mounting base 2, and the water inlet is located at the bottom surface of the mounting base 2, and the second gear 35, the third gear 36, and the fourth gear 37 are located on the top surface of the mounting base 2. In this way, even if the shell leaks, it will not affect the second gear 35, the third gear 36, and the fourth gear 37, and will not affect the motor 1. Therefore, the waterproof effect of the motor 1 is good and the service life is longer. Especially when processing gel liquids, it can effectively protect the motor and other gear parts to prevent the motor from getting stuck.

[0025] Although the present disclosure has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present disclosure can be implemented in a variety of forms without departing from the spirit or essence of the utility model, it should be understood that the above-mentioned embodiments are not limited to any of the foregoing details, but should be widely interpreted within the spirit and scope defined by the appended claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
