TECHNICAL FIELD
[0001] The utility model relates to the field of industrial protective cover, concretely relates to a full-protection safety cover for impeller dynamic balancing. BACKGROUND
[0002] With the continuous progress of modern industrial technology, impeller dynamic balancing machines play a crucial role in improving the performance and stability of mechanical equipment. As the core component of many rotating machines (such as compressors, fans, pumps, etc.), the balance state of the impeller directly affects the running efficiency, vibration level, and noise output of the equipment. Under high-speed rotating conditions, the imbalance of the impeller can cause severe vibration and noise, shorten the service life of the equipment, and even cause safety accidents. Therefore, accurate dynamic balancing test and adjustment of the impeller are key steps to ensure efficient and stable operation of the equipment.
[0003] In the current application of impeller dynamic balancing machines, a significant safety hazard is the lack of effective protective measures during the test process. When the impeller rotates at a speed of thousands of revolutions per minute, if it has manufacturing defects, improper installation, or excessive imbalance, it may cause debris to fly. In the absence of a protective cover, these flying objects pose a direct threat to the safety of surrounding operators, which may cause serious physical injuries such as cuts and impact injuries. Historically, similar accidents have occurred frequently in high-speed rotating equipment testing, highlighting the urgency of safety protection.
[0004] In addition, open impeller dynamic balancing machines also face the problem of environmental pollution. Dust, oil stains, and other pollutants in the air are easily attached to key components such as impellers, sensors, and guide rails, affecting test accuracy and accelerating equipment wear and tear, reducing service life. Long-term exposure to harsh environments, equipment components are easily affected by natural factors such as ultraviolet radiation and temperature fluctuations, leading to aging of plastic components and rusting of metal components, further reducing equipment performance.
[0005] Noise pollution cannot be ignored either. The noise generated by the impeller dynamic balancing machine during high-speed operation will directly spread to the working environment without the soundproofing effect of the protective cover, endangering the hearing health of the operators, interfering with work efficiency, and long-term exposure may cause hearing loss, tinnitus, and other occupational diseases. At the same time, noise pollution also reduces the comfort of the working environment, increases the psychological pressure of the operators, and further affects work efficiency and quality.
[0006] More seriously, the lack of a protective cover for the impeller dynamic balancing machine during operation may pose a risk of weight block falling, tools or parts displacement due to air flow vibration, which not only threatens the safety of the operators, but also may interfere with the accuracy of the test, even leading to test failure.

[0036] Example 1
[0037] As shown in the accompanying drawings Figures 1-2 , the embodiment provides a full-protection safety cover for impeller dynamic balancing, which comprises a sliding door 1, a safety lock 2, a sliding handle 3, a walking slide rail 4 and a digital display screen 5.
[0038] As shown in the accompanying drawings Figure 1 , the sliding door 1 is in the shape of an arch and is in sliding connection with the two walking slide rails 4. The span of the sliding door 1 corresponds to the distance between the two walking slide rails 4, so as to isolate the space inside and outside the door. The sliding door 1 can be made of steel plate, lead plate or aluminum plastic plate, and the thickness is generally 2-4 mm. If the rotating speed of the impeller dynamic balancing machine 6 is high, the thickness can be increased to 10 mm to withstand the collision of high-speed flying objects or heavy objects. The arch-shaped door conforms to the shape of the impeller machine, which is conducive to space utilization, reduces dead angles and reduces noise.
[0039] The safety lock 2 is arranged on the sliding door 1 and is used to lock the sliding door 1 when the impeller dynamic balancing machine 6 is running. The safety lock 2 ensures that the sliding door 1 remains in the locked state during the running of the impeller dynamic balancing machine 6, preventing injuries caused by accidental opening of the door and increasing the safety of the system.
[0040] The sliding handle 3 is arranged on the waist of the sliding door 1. The handle can increase the texture, increase the friction and gripping force, and prevent slipping. According to the actual application scene, if there are more liquid oil stains, the sliding handle 3 is easy to get dirty, and a hollow design of stainless steel material can be selected.
[0041] The digital display screen 5 is arranged on the sliding door 1 and is used to display the rotating speed and unbalance of the impeller dynamic balancing machine 6. The digital display screen 5 is electrically connected with the console 8 of the impeller dynamic balancing machine 6, and the digital display screen 5 is used to copy and display the screen information of the console 8. The digital display screen 5 completely copies the screen information of the console 8, which is convenient for the staff to observe and debug the equipment at close range, and can timely respond to the corresponding test data and quickly open the protective safety cover for debugging.
[0042] The digital display screen copies and displays the console information, so that the operator can monitor the machine state without approaching the console, improving the convenience and efficiency of operation. The digital display screen provides information reference for entering the interior, and selects the time to enter the interior by repeatedly opening and closing the sliding door, increasing the convenience and reliability.
[0043] A drawing board and a pen can also be arranged beside the digital display screen 5, which is used to briefly record the mass distribution of each part of the impeller. When the unbalance of the impeller is not easy to detect, the unbalance value at different rotating speeds can be recorded. When the unbalance is determined, a reflective strip can be pasted, and after debugging, a test weight can be added at the corresponding position and recorded on the drawing board.
[0044] As Figure 2 shown, the sliding protective door 1 is at least two, to two sliding protective doors 1 away from each other and towards each other to complete the opening and closing; double opening compared to single opening protective door, more suitable for larger space inside, and facilitate personnel in the impeller balancing machine around the full range of operations, increase the utilization of space.
[0045] As Figure 3 shown, the sliding protective door 1 in the direction of the span is provided with an openable protective grid 7, so as to facilitate personnel to enter; protective grid 7 has good light transmittance and visibility, which is convenient for personnel to look inside from outside, and can better prevent large debris or parts from flying out. If necessary, a tempered glass door can be additionally provided outside the protective grid 7 to further improve the strength of the protection, prevent small debris and oil stains, and isolate noise.
[0046] The warning light 9 is installed on the sliding protective door 1, and the warning light 9 is electrically connected with the console 8 of the impeller dynamic balancing machine 6.

[0050] Example 2
[0051] The main difference between this embodiment and embodiment 1 is:
[0052] This embodiment also includes an alarm and a button provided on the sliding protective door 1 for making loud calls for help around in case of an accident. The alarm and button provide a quick way to notify people around, improving the ability to handle emergencies in emergency situations.
[0053] It also includes a lighting lamp provided on the inner side of the sliding protective door 1. The lighting lamp improves the visibility of the working environment, especially in insufficient light, enhancing the safety of operation.
[0054] Principle of full protection safety cover:
[0055] When the impeller dynamic balancing machine 6 is powered on, the safety lock 2 is in the locked state, and the digital display screen 5 is a copy screen of the operation platform screen, displaying the running information of the impeller dynamic balancing machine 6;
[0056] When the impeller dynamic balancing machine 6 is powered off, the safety lock 2 is in the unlocked state, and the operator can pull open the sliding protective door 1 to adjust the weight or punch the hole of the impeller; go back to the previous step until the impeller dynamic balancing machine 6 displays: the impeller has been in the dynamic balance state.
[0057] The practical advantages of the full protection safety cover are as follows:
[0058] The closed design of the protective cover can reduce the interference of external air flow, vibration and other factors on the impeller dynamic balancing test, improving the accuracy and reliability of the test; this is crucial for ensuring the quality and performance of the impeller; the digital display screen 5 is used to copy and display the screen information of the control console 8, which facilitates the quick and repeated close observation and debugging of the equipment by the staff, and improves the efficiency of the connection between on-site observation and data analysis.
[0059] In the impeller dynamic balancing test, if the high-speed rotating impeller fails, such as blade loosening or breaking, it will produce high-speed flying debris. The protective cover can effectively block these flying objects, protecting the operator from injury and ensuring the safety of the test process. When the operator is installing, debugging or maintaining the impeller, he or she may inadvertently approach the rotating impeller. The protective cover, as a physical barrier, can prevent body parts from being drawn into rotating components, significantly reducing the risk of personal safety.
[0060] The sliding rail design makes the opening and closing of the protective cover more smooth and convenient. The operator can easily slide the protective cover open or closed, facilitating the installation, disassembly and debugging of the impeller, and improving work efficiency. The design of the protective cover usually takes into account the needs of impellers of different sizes and shapes, and can be flexibly adjusted to adapt to different models of impeller dynamic balancing machines 6, meeting the diverse test needs.
[0061] The protective cover can prevent dust, oil stains, moisture and other external pollutants from entering the inside of the impeller dynamic balancing machine 6, reduce the wear and corrosion of the equipment, and thus prolong the service life of the equipment. When maintenance is needed for the impeller dynamic balancing machine 6, the protective cover can be easily opened, allowing the operator to easily access all parts of the equipment for cleaning, lubrication, inspection and other work, ensuring the normal operation of the equipment.
[0062] The protective cover can absorb and isolate the noise generated by the rotation of the impeller to a certain extent, reduce the noise level of the working environment, protect the hearing health of the operator, and reduce the psychological impact. The protective cover can prevent the spread of debris, oil stains and other pollutants generated during the test to the surrounding work area, maintain the cleanliness and hygiene of the working environment, and facilitate subsequent cleaning work. This helps to improve the comfort and work efficiency of the operator.
[0063] The above embodiment is only one of the implementation manners of the technical scheme of the present application, and the scope of protection of the present application is not limited to the above embodiment, but also includes any changes, substitutions and other implementation manners that are easily thought of by those skilled in the art within the technical scope disclosed by the present application.
