light tank welding machine- China Factory Manufacturers Suppliers

Tank welding machine is actually a transformer with lower external characteristics, which converts 220V and 380V alternating current into low-voltage direct current. Generally, welding machines can be divided into two types according to the output power type, one is AC power and the other is DC.

What is a tank welding machine?

The tank welding machine can be said to be a high-power rectifier. It is divided into positive and negative poles. When AC power is input, it is transformed by a transformer, and then rectified by the rectifier, and then outputs a power supply with reduced external characteristics.

 

The output terminal is on and off. When it is turned on, a huge voltage change will be generated. When the two poles are short-circuited in an instant, the arc will be ignited. The arc will be used to melt the electrode and the welding material, and the purpose of combining them will be achieved after cooling. Welding transformers have their own characteristics,The external characteristic is the sharp drop in voltage after the electrode is ignited.

 

What are the specific types of tank welding machines?

1. Light tank welding machine is mainly full rivet type or mixed rivet and welding.

2. The medium tank welding machine is to forge several steel molds, then fill with solder and directly weld.

3. Heavy-duty tank welding machine, the steel plate is forged into a gear staggered shape, first buckled like a button, and then filled with solder, mainly to reduce the burden of the heavy armor on the solder.

 

Working principle of tank welding machine.

The main component of the tank welding machine is a step-down transformer. The two ends of the secondary coil are the work piece and the electrode to be welded. They will ignite the arc during operation and weld the electrode to the gap of the work piece under the high temperature of the arc. Because the iron core of the tank welding machine transformer has its own characteristics, it has the characteristics of a sharp drop in voltage, that is, the voltage drops after the electrode is ignited; when the electrode is short-circuited due to adhesion, the voltage drops sharply.

 

During the welding operation of the welding machine, although the current in the circuit is equal everywhere, since the resistance is different everywhere, the resistance at the unfixed contact is the largest. According to the law of thermal effect of flow, Q = IRt: When the current is equal, the greater the resistance, the higher the heat generation. Therefore, in the welding process, the contact resistance of the electrode contact point as the contact point of the metal body is the largest, so the electric heat generated in this part is naturally the largest, and the electrode is an alloy with a lower melting point.

 

The tank welding machine first uses a pulse generating circuit such as a 555 time base circuit to generate a rectangular pulse wave, then uses a transistor for current amplification, and then uses a pair of complementary field-effect transistors for voltage amplification to generate high-frequency signals, and finally uses the transformer with To boost the voltage, and get the induced alternating current on the secondary winding. Its power depends on the amplification capability of the amplifying circuit.

 

Tank welding machines mostly use single-ended forward inverter circuits composed of IGBT tubes, and most of their control systems use pulse width modulation chip SG3525. The inverter frequency is 20kHz, which can control the external characteristics of constant current.

 

When the system is at no load, the PWM modulator will output pulses intermittently due to voltage feedback control. Due to the low frequency of intermittent oscillation and narrow pulse width, not only the no-load loss is small, but the transformer is not easily saturated. Because this kind of welding machine adopts the control technology with pulse width modulation PWM as the core.

What is the working principle of the simple chunk type hydraulic jack?

Simple chunk type hydraulic jack (package unit) is evenly distributed around tank inner wall. Tank top and upper (the first layer) wall plates are lifted first and then install and weld wall plates of tank body. Self locking hydraulic jack and hydraulic hoist composing of lifting frame and lifting rod are adopted. When oil enters hydraulic jack, upper clamp fastens and lifts lifting rod and expansion ring and mobilize tank (including tank top) to ascend upward. When oil returns to jack, upper clamp returns with piston and lower clamp automatically fastens lifting rod without gliding. The simple chunk type hydraulic jack repeats the movement and make lifting rod ascend with tank to designated height (spare height for next layer of plate). After butt weld of next layer of wall plates, open upper and lower loosening device and loosen upper and lower clamp to make lifting rod and expansion ring descend to lower expanded and welded rib plate of the next layer of wall plates and then lift. Repeat the process and ascend welded tan till the last layer of wall plates are installed and welded. The installation of the whole storage tank is completed.

With the progress of social and economic development, people's demand for resources continues to increase, from automobiles that require diesel to power plants that require petroleum. In short, oil, natural gas and other resources have become indispensable things in people's daily life, so people gradually invented pipeline transportation methods. Next, I will introduce pipeline construction equipment in detail.

What are the reasons for using pipeline construction equipment

Due to the large volume of pipeline transportation, most of the pipelines are buried underground, occupying a small area, less terrain and object constraints, and short transportation distances.

 

Use pipeline construction equipment for sealed transportation, safe and reliable, long-term continuous and stable operation, easy to manage, easy to maintain, and realize remote centralized monitoring.

 

Therefore, a large number of pipeline laying work has been carried out in various countries, and related companies specializing in pipeline construction equipment have been derived. WINCOO is a company specializing in pipeline construction equipment.

 

What is the specific process of pipeline construction

There are many factors that can lead to operational defects in pipeline construction, such as inadequate installation technology, long construction period or insufficient supervision. Relevant technical personnel should be careful, careful, and concentrate on research and judgment when inspecting and accepting pipeline construction equipment.

 

Provide feedback and resolve the issue as quickly as possible. If the existing safety quality is not reached, the target area should be immediately compensated to ensure that the pipeline construction equipment can continue to operate safely. And maintain the original economic cost.

 

Specific process introduction:

Measuring arrangement→cleaning the construction work area; construction road→conveying anticorrosion pipe→processing tank→distributing pipe→preparing nozzle; pipeline assembly→pipe assembly and welding→welding joint inspection→heat shrinkable casing (tape) bushing→ trench excavation →Appearance repair.

 

What pipeline construction equipment is needed during pipeline construction

The following pipeline construction equipment is needed during pipeline construction:

l Transport anticorrosive pipe

l Pipe assembly

l Pipe assembly and welding

l Heat shrinkable sleeve (tape) bushing

 

With the continuous development of society, the demand for pipelines is also increasing, and the pressure on pipelines is increasing. During the installation and operation of pipeline construction equipment, welding is a basic technical job and also a vital job.

 

The safe and stable operation of pipeline construction equipment plays a key role in the overall pipeline operation. Therefore, increasing attention to the construction quality of pipeline construction equipment can lay a solid foundation for the normal operation of the factory!If you want to know more about high-quality pipe spool fabrication lines, you can also contact us at any time.

A gas cylinder is a pressure vessel for storage and containment of gases at above atmospheric pressure.High-pressure gas cylinders are also called bottles.Inside the cylinder the stored contents may be in a state of compressed gas, vapor over liquid, supercritical fluid, or dissolved in a substrate material, depending on the physical characteristics of the contents.
