Description

Technical Field

[0001] This utility model belongs to the field of centrifugal pump protection technology, and in particular relates to a horizontal centrifugal pump packing oil stain protection device. Background Technology

[0002] In the construction of standardized electromechanical equipment chambers in underground coal mines, the No. 4 and No. 5 central water pump rooms are equipped with horizontal centrifugal pumps. These pumps require continuous lubrication and sealing at the packing. However, during the high-speed rotation of the shaft sleeve, the grease is easily thrown out by centrifugal force, forming oil sludge accumulation around the pump. This problem not only makes it difficult to maintain hygiene in the chamber, increasing the daily cleaning workload for pump operators, but also makes the floor slippery, increasing the risk of falls. More seriously, a fall could result in the person accidentally penetrating the rotating shaft at the pump packing, posing a risk of mechanical injury. This not only fails to meet the construction requirements of standardized electromechanical chambers but also poses a serious threat to the personal safety of workers. Currently, there is a lack of protective devices specifically designed for this type of pump structure, failing to effectively solve the dual problems of oil splashing and safety protection. Utility Model Content

[0003] The purpose of this invention is to provide a horizontal centrifugal pump packing oil contamination protection device to solve the problems of oil splashing from pump packing and personnel safety hazards in the prior art.

[0004] The present invention adopts the following technical solution: a horizontal centrifugal pump packing oil stain protection device, including an inverted arc-shaped top cover, two handles on the top cover, and support plates extending downward along both sides of the top cover. Each support plate has a bottom plate horizontally arranged at its bottom end. Two straight grooves are opened on one support plate, and the space between the two straight grooves is a baffle. The top cover is used to cover the bearing sleeve on the side of the horizontal centrifugal pump that is not connected to the motor, and the two straight grooves are used to provide space for the pipeline of the horizontal centrifugal pump. Furthermore, the width of the top cover is 30-40cm, the radius of the top cover is 20-30cm, and the height of the support plate is 70-80cm.

[0005] Furthermore, the width of the straight groove is 3-5cm, and the width of the baffle is 2-4cm. Furthermore, the handle and the top cover are either integrally molded or detachably fixedly connected.

[0006] The beneficial effects of this utility model are as follows: This utility model is precisely designed for the structural characteristics of downhole horizontal centrifugal pumps, possessing significant practical value and safety benefits. Firstly, the combination of the inverted arc-shaped top cover and baffle effectively blocks grease splashed from the pump packing, significantly reducing the area of ​​oil splatter and ensuring a clean electromechanical chamber floor, fully meeting the hygiene requirements of standardized chambers. Secondly, it eliminates the need for frequent oil cleaning by operators, saving cleaning time per shift, reducing labor intensity, and decreasing the consumption of personal protective equipment and cleaning supplies, thus lowering operating costs. Thirdly, the protective device forms a physical barrier, preventing personnel from slipping and falling on the rotating shaft, fundamentally eliminating mechanical injury accidents and providing reliable safety for operators. Fourthly, it allows operators to easily move the protective device and evenly apply grease to the pump packing, effectively enhancing the sealing performance of the pump packing.

[0008] The components are: 1. Top cover, 2. Baffle, 3. Bottom plate, 4. Support plate, 5. Handle, 6. Straight groove. Detailed Implementation

[0009] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0010] This utility model provides a horizontal centrifugal pump packing oil contamination protection device, such as... Figure 1 and Figure 2 As shown, it includes an inverted arc-shaped upper cover 1, with two handles 5 on the upper cover 1. Support plates 4 extend downward along both sides of the upper cover 1, and a bottom plate 3 is horizontally provided at the bottom end of each support plate 4. Two straight grooves 6 are provided on one support plate 4, and a baffle 2 is located between the two straight grooves 6. The top cover 1 is used to cover the bearing sleeve at the end of the horizontal centrifugal pump that is not connected to the motor, and the two straight grooves 6 are used to provide space for the pipeline of the horizontal centrifugal pump. This horizontal centrifugal pump packing oil contamination protection device uses an inverted arc-shaped top cover to cover the bearing sleeve to block oil contamination, and straight grooves to avoid the pipeline, achieving protection and compatibility with normal equipment operation.

[0011] In some embodiments, the width of the top cover 1 is 30-40cm, the radius of the top cover 1 is 20-30cm, and the height of the support plate 4 is 70-80cm.

[0012] In some embodiments, the width of the straight groove 6 is 3-5 cm, and the width of the baffle 2 is 2-4 cm. Specifying the widths of the straight groove and the baffle ensures that the pipeline can be placed smoothly without obstruction, while also allowing the baffle to effectively intercept splashed grease, thus balancing the functionality and practicality of the device. In some embodiments, the handle 5 and the top cover 1 are integrally formed or detachably fixedly connected. The integrally formed handle structure is sturdy and durable, while the detachable type facilitates transportation and maintenance, improving the flexibility and reliability of the device.

[0013] The following is a method for using a horizontal centrifugal pump packing oil contamination protection device: Before use, ensure the horizontal centrifugal pump is stopped and powered off to ensure operational safety. First, align the device with the two straight grooves on the support plate of the protection device according to the pump pipeline location. Move the oil contamination protection device horizontally to the outside of the bearing sleeve at the end of the pump not connected to the motor. Ensure the top cover completely covers the bearing sleeve and packing area, ensuring the baffle is directly opposite the oil outlet of the packing and the pipeline is accurately embedded in the straight groove to prevent pressure on the pipeline or affecting the device's fixation. Next, check that the base plate fits tightly against the equipment mounting surface to ensure the device is placed stably without shaking. After installation, the device position can be easily adjusted or disassembled using the handle. In daily use, no additional operation of the protection device is required; it continuously provides oil contamination blocking and safety protection. When maintenance of the pump packing or bearing sleeve is required, simply grasp the handle to move the entire device away. After maintenance, reinstall and reset it according to the above steps. The operation is simple and efficient, and does not affect the normal equipment maintenance process.
