Explanation of common fault problems of solid state high frequency welder

 Solid state high frequency welder is a relatively common advanced welding equipment today. Compared with traditional welding equipment, solid state high frequency welder has many advantages, but no matter how good the equipment is, there will be problems. Today, I will explain the solid state high frequency welder to you. Common faults of frequency welding machines.

Baoding Chaochang Electromechanical Co., Ltd. mentioned that the solid state high frequency welder has many protection devices. When there are problems such as over-temperature, over-current, over-voltage, and lack of equality, an alarm will be issued. The following will explain the fault in detail. reason:

1. Water shortage protection alarm: This situation is mostly caused by the reverse connection of the water pipe, insufficient power or pressure flow of the water pump (the machine tool cooling pump cannot be used) and the blockage of the water circuit.

2. Overheating protection alarm: This situation is mostly caused by insufficient water flow, too little cooling water or blocked water channels.

3. Overcurrent protection alarm: This situation is mostly due to the incorrect shape and size of the self-made induction coil, short-circuit and sparking between the workpiece and the induction coil or the induction coil itself, the distance between the workpiece and the induction coil is too small, and the prepared induction coil In use, it is affected by the customer's metal fixture or adjacent metal objects.

4. Overvoltage protection alarm: This situation is mostly due to the fact that the grid voltage is too high and exceeds the rated voltage by more than 10% or is used when the power consumption is low.

5. Phase loss protection alarm: This situation is mostly caused by serious unbalance of three-phase power, lack of one phase of three-phase power, or an open circuit in the air switch or power supply line.

6. The equipment suddenly stops working: This situation is mostly caused by the too small gap between the workpiece and the induction coil, the incorrect shape and size of the self-made induction coil, or the short circuit between the workpiece and the induction coil or the induction coil itself. .

The above is an analysis of the common fault problems of solid state high frequency welders. I hope the above knowledge can be helpful to everyone.

The Main Reasons Why Heat Pumps Run Continuously

图片
For most homeowners, having a  heat pump ​ running constantly can be confusing. This is because most people are usually unsure if this should be happening. So, is it normal for your heat pump to run constantly or should you be worried?  Should My Heat Pump Run All the Time? Most  Swimming Pool Heat Pump  will run continuously during cold weather. This means that it is normal for your heat pump to run continuously during the winter when the temperature is equal to or below 30 degrees.   The Main Reasons Why Heat Pumps Run Continuously Your Thermostat is Not Set Properly Setting your thermostat too high in the winter or too low in the summer may cause it to run constantly as it tries to keep up with the temperature you set. Make sure the emergency heat mode is not set as well. Setting your thermostat incorrectly or realizing that someone has set it to an incorrect setting may cause you problems. Your Air Filter Needs to Be Cleaned In order for a heat pump to ...

PE Jaw Crusher vs. PEX Jaw Crusher: Which is Right for You?

图片
 Choosing the right crusher for your mining or construction project can be a daunting task. Two common types of crushers are the  PE jaw crusher ​ and the PEX jaw crusher. While both are designed to reduce the size of materials, they have distinct characteristics and applications. Let's delve into the key differences between these two types of crushers. Structure and Working Principle PE Jaw Crusher:  The PE jaw crusher features a fixed jaw and a swinging jaw, which move towards each other to crush material. The crushing chamber is typically V-shaped, and the material is compressed and crushed between the jaws. PEX Jaw Crusher:  The PEX jaw crusher is a more advanced design that incorporates a laminated plate and a toggle plate. This design allows for a larger crushing chamber and a more efficient crushing process. Applications PE Jaw Crusher:  PE jaw crushers are primarily used for primary crushing of hard and abrasive materials, such as rocks, ores, and c...

What is the use of Y pipe fitting?

图片
Y pipe connectors , an integral part of the plumbing lexicon, are engineered marvels that offer solutions to a myriad of fluid distribution challenges. These connectors, also known as Y fittings, are designed to efficiently split or combine the flow in a piping system, proving indispensable across an array of applications. In residential settings, Y pipe connectors are often used to distribute water to multiple outlets, such as faucets and showerheads, ensuring an even and reliable supply. They are also crucial in irrigation systems, where water must be directed to various points in a garden or farmland. The commercial sector benefits from Y pipe connectors in HVAC systems, where they help in the distribution of conditioned air or in the plumbing of commercial kitchens, directing water to multiple sinks and appliances. In industrial applications, these connectors play a vital role in the chemical and pharmaceutical industries, where precise fluid mixing and distribution are required fo...
