Common faults of variable frequency motors include:1. Inter turn short circuit and partial discharge: This is a common form of insulation type faults in variable frequency motors. Interturn short circuit is generally manifested as extensive damage to a coil in the motor, while partial discharge may occur when the motor coil looks good outside, but ...
2024-05-2114510What are the structural differences between synchronous motors and asynchronous motors?
2024-05-20146201.Firstly, check the main circuit. Whether the power supply is powered on, whether the voltage is normal, whether the starting overload fuse is burnt out, whether the air switch is tripped, whether the switch contact is intact, and whether the power supply is out of phase. When starting, observe the voltmeter and ammeter. When the industrial chille...
2024-05-2013310There are many reasons for random fracture of gear teeth, mainly including:1) Random fracture is usually caused by tooth defects, pitting, peeling, or other stress concentration sources forming excessively high local stress concentrations at that location.2) Under the action of alternating stress, defects such as inclusions and fine grinding crack...
2024-05-2014110Do you know the reason why the 57 stepper motor and synchronous belt on the X-axis, which was just adjusted in the past two days, lost its step again?At the beginning, the tensioning structure of the synchronous belt was adjusted to ensure that the tensioning force of the synchronous belt was strong enough, but there were still cases of slipping.
2024-05-1614420The modulus pressure angle and helix angle determine the pitch of the base circle, and adding the number of teeth determines the size of the base circle. The size of the base circle determines the shape of the involute. To understand the definition of modulus, it is actually a parameter that is close to a coefficient and cannot be directly measured...
2024-05-1610110It is inevitable to encounter malfunctions when using industrial chillers. Below are several common malfunctions and their causes during the use of chillersOil pressure alarm occurs during useCommon causes of oil pressure alarm in chillers:1. The internal parts of the chiller have not been inspected and cleaned, resulting in oil stains, oil pump f...
2024-05-1613810Laser marking is currently one of the most widely used laser processing technologies. Its principle is to use a highly concentrated laser beam to instantly evaporate part of the material surface, forming an indelible mark. Laser marking has the advantages of fast speed, good texture, and high accuracy, and has been widely used in many industries su...
2024-05-1512220Hi, I have the Rudia RDC6563FG-Lite and have some questions about the controller, It says it supports 5v and 24v output limit switches and there is a Limit polarity setting for positive and negative on software but changing this setting cause no change and limit is only triggered by GND connection. Am I doing something wrong or is PNP not supported...
2024-05-1415810During use, the performance of a chiller will gradually decrease over time. In fact, many faults have some precursors before they occur, which are commonly referred to as potential faults.The failure rate of a chiller also varies over time, which is commonly referred to as its lifespan.1. Phase 1: Early FailureEarly failures, also known as the br...
2024-05-1513010Laser marking is currently one of the most widely used marking and processing methods. The patterns or text produced by laser marking have a good texture and are indelible. They are often used in packaging, advertising, cables, consumer electronics and other products. Laser marking can be applied in both large-scale factories and small workshops, b...
2024-05-15127101. Check the operating environment.Ensure that the water-cooled industrial chiller is placed in a well ventilated and temperature appropriate environment, avoiding direct sunlight or excessively humid environments, which helps the water-cooled industrial chiller maintain good working conditions.2. Check if the cooling water circulation system is ...
2024-05-1413510Double speed chain transmission is a mechanical transmission device used for transmitting power and motion, mainly used for producing or transporting various materials through transmission. Of course, the main methods of double speed chain transmission include efficiency, reliability, and flexibility.1、 The Efficiency of Double Speed Chain Transm...
2024-05-1415110Electric energy is one of the most important sources of energy in modern society, and motors are devices that convert electrical energy into mechanical energy. Electric motors are widely used in various industries such as machinery, metallurgy, petroleum, coal, chemistry, aviation, transportation, agriculture, and others. With the continuous improv...
2024-05-1413810In the field of material processing, laser technology has gradually become the preferred choice for industrial processing. Whether metal or non-metal materials, lasers can efficiently and accurately complete processing tasks, and achieve no deformation, small thermal reactions, and smooth edges. At present, laser processing tasks include cutting, c...
