Description

Technical Field

[0001] This utility model belongs to the field of steam-driven feedwater pump installation technology, and relates to a steam-driven feedwater pump oil baffle installation tool. Background Technology

[0002] During on-site maintenance of steam-driven feedwater pumps, the installation of the oil baffle is usually difficult. The installation method is usually to push the oil baffle in by hand and knock it in with a copper rod. This operation is cumbersome, poses safety hazards, and can easily damage the pump oil baffle and its seals.

[0003] Chinese utility model patent CN209184424U discloses a special installation tool for a motor oil baffle ring. The oil baffle ring is sleeved on the motor shaft, and the special installation tool includes a sleeve, an mounting ring, and a base plate. The sleeve has a cylindrical structure; the mounting ring has a disc structure and is located at one end of the sleeve; the base plate has a disc structure and is located at the other end of the sleeve; the sleeve, mounting ring, and base plate are coaxial, with the end face of the mounting ring abutting against the motor oil baffle ring, and the end of the motor shaft inserted into the sleeve from one end of the mounting ring. In this technical solution, the motor oil baffle ring can be smoothly installed by abutting the end face of the mounting ring against the motor oil baffle ring and simultaneously striking the base plate with a hammer. However, this technical solution still requires striking with a hammer to install the oil baffle ring, which is time-consuming and laborious, affecting the work efficiency of the operator. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a tool for installing an oil baffle on a steam-driven feedwater pump, which effectively solves the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A steam-driven feedwater pump oil baffle installation tool includes a sleeve fitted on the feedwater pump rotor. One end of the sleeve is in contact with the side of the oil baffle, and the other end of the sleeve is provided with a top plate. A threaded pull rod is inserted into the center of the top plate. One end of the threaded pull rod is threaded to a feedwater pump terminal. A planar pressure bearing fitted on the threaded pull rod is provided on the side of the top plate away from the sleeve. A threaded pressure plate is threadedly connected to the threaded pull rod, and the threaded pressure plate is in contact with the side of the planar pressure bearing.

[0006] Furthermore, a guide sliding sleeve that contacts the side of the threaded tie rod is provided inside the top plate.

[0007] Furthermore, the guide sliding sleeve is made of copper.

[0008] Furthermore, two tightening pin holes are symmetrically provided on the circumferential side of the threaded pressure plate.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] This utility model achieves rapid installation of the oil baffle through a sleeve, top plate, threaded pressure plate, flat pressure bearing, and threaded tie rod, improving the installation efficiency of the workers. The guide sliding sleeve enables the movement and guidance of the sleeve, ensuring the reliability of the sleeve during use. The tightening pin hole enables rapid rotation of the threaded pressure plate, improving the convenience for workers when rotating the threaded pressure plate. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figure 1 , Figure 2 As shown, a tool for installing an oil baffle on a steam-driven feedwater pump includes a sleeve 3 fitted onto the feedwater pump rotor 1. One end of the sleeve 3 is fitted against the side of the oil baffle 2, and the other end of the sleeve 3 is integrally formed with a top plate 4. A threaded pull rod 5 is inserted into the center of the top plate 4. One end of the threaded pull rod 5 is threaded to the feedwater pump terminal. A planar pressure bearing 8 fitted onto the threaded pull rod 5 is provided on the side of the top plate 4 away from the sleeve 3. The planar pressure bearing 8, also known as a "planar thrust bearing," is existing technology and will not be described in detail here. A threaded pressure plate 6 is threadedly connected to the threaded pull rod 5, and the threaded pressure plate 6 is fitted against the side of the planar pressure bearing 8.

[0016] In this embodiment, a guide sliding sleeve 9 that contacts the side of the threaded tie rod 5 is installed inside the top plate 4 by interference fit.

[0017] In this embodiment, the guide sliding sleeve 9 is made of copper.

[0018] In this embodiment, two tightening pin holes 7 are symmetrically opened on the circumferential side of the threaded pressure plate 6.

[0019] The working principle of this technical solution is as follows: During installation, the operator places the oil baffle 2 on the water pump rotor 1, then passes the threaded tie rod 5 through the top plate 4 and fixes it to the end of the water pump rotor 1 with threads. Then, the guide sliding sleeve 9 is installed in the top plate 4, and the flat pressure bearing 8 and the threaded pressure plate 6 are installed on the threaded tie rod 5 in sequence. In use, the operator can insert the pin into the tightening pin hole 7, and then hold the pin to drive the threaded pressure plate 6 to rotate. Under the action of the threads, the threaded pressure plate 6 pushes the sleeve 3 along the threaded tie rod 5 to move towards the water pump rotor 1, thereby driving the oil baffle 2 to enter the water pump rotor 1 evenly and smoothly. While the threaded pressure plate 6 rotates, the flat pressure bearing 8 can prevent the threaded pressure plate 6 from driving the sleeve 3 to rotate, ensuring the reliability of the sleeve 3 in use.

[0020] Preferably, before installation, the operator can mark the insertion depth of the oil baffle 2 using a length ruler to prevent improper installation or excessive insertion depth. Alternatively, a 380V electric servo drive control device can be used to rotate the threaded pressure plate 6 to improve the convenience and accuracy of the oil baffle 2 during installation.

[0021] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
