Impeller dynamic balancing machine operation and application tutorial
Guangzhou Zhuo Xuan Jin Dynamic Balancing Machine Co., Ltd. is committed to the development and production of dynamic balancing machine for more than ten years. The impeller dynamic balancing machine produced by the company has been successfully trusted by many wind turbine manufacturers. With our company purchasing many dynamic balancing machines, the impeller dynamic balance What are the needs of the use of the machine? The following small series will introduce the specifications of the impeller dynamic balancing machine:
First, the applicable object: the impeller dynamic balance detection of the hard support balance machine, through the electronic sensing test, reduce the unbalance of the fan impeller to the standard range, to ensure the normal operation of the fan, improve the quality of the product, and reduce the product noise. And improve the life of the product.
Second, preparation work
1. First understand the specifications of the impeller that is to be tested for dynamic balance, and adjust the appropriate size of the hard support shaft diameter according to the specifications.
2. Prepare suitable iron bars for counterweights and the balance of the plate for measurement.
3. The impeller for the dynamic balance test should first adjust the clearance of the impeller in the fan cylinder, and ensure that it does not sweep during normal operation in the fan cylinder, and finally smooth and smooth the grinding to ensure the accuracy of the dynamic balance test.
4. Before the test, check the dynamic balancing machine first. For example, the electrical line connector should be firm, the grounding wire is firm and reliable, and the mechanical part is flexible and properly lubricated.
5. After confirming that the balance test impeller is within the range of the balancer, install the impeller in the dynamic balance test shaft for the machine test.
Third, the operation of the dynamic balancing machine
1. Turn on the total power of the device
2. Start balancing the electrical and electrical box power supply.
3. Set the test parameters and enter the electrical test box.
4. Start the balancing machine to rotate the impeller and test the impeller imbalance.
5. After determining the balance weight position of the tested impeller, the weight of the weight is measured by the balance of the plate, which is consistent with the unbalanced balance of the test and welded to the unbalanced position determined by the impeller.
6. After soldering, reinstall the dynamic balancing machine and retest until the required balance accuracy is reached. The unbalanced allowance is required to be ≤2g.mm.
Fourth, matters needing attention
1. When testing the initial unbalance of the impeller, the imbalance of the impeller may be large. When starting the balancing machine, the lower speed can be used to avoid damage to the balancer rotating the test component.
2. The weight of the impeller in the unbalanced weight area should be welded firmly to avoid falling during the test.
3. When the weight of the impeller is welded, the impeller should be removed from the balancer to one side for welding. At the same time, care should be taken to prevent the welding spatter from adhering to the balance test shaft.
4. Welded weight iron block should be cleaned after each welding, so as not to affect the test accuracy.
5. After the impeller test is completed, it should be handled lightly and gently to avoid bumping. After the test, the impeller should not be processed again, so as not to affect the balance accuracy of the test.
Guangzhou Zhuo Xuanjin engineer reminds: Balance machine is a high-precision measuring instrument after all, maintenance personnel require certain electrical knowledge, especially weak electricity knowledge, so choose the approved professional maintenance as much as possible, Guangzhou Zhuo Xuan Jin balance machine after-sales service consulting :020-36969823.
