Anyone with a little mechanical knowledge knows that energy can be transformed into each other. It is best to apply this knowledge to the tank hydraulic jacking system to explain the power loss of the hydraulic system. Next, we will introduce in detail how to maintain the tank hydraulic jacking system.
Here is the content list:
l Maintain the tank hydraulic jacking system from the perspective of power source.
l Maintain the tank hydraulic jacking system from a pressure perspective.
l Maintain the tank hydraulic jacking system from the perspective of speed regulation.
Maintain the tank hydraulic jacking system from the perspective of power source.
On the one hand, the power of tank hydraulic jacking system will cause energy loss and reduce the overall efficiency of the system. On the other hand, this part of the energy lost will be converted into heat energy, which will increase the temperature of the hydraulic oil and the deterioration of the oil. The tank hydraulic jacking system is malfunctioning. Therefore, when designing a tank hydraulic jacking system, under the premise of meeting the requirements of use, full consideration should be given to reducing the power loss of the system.
First of all, considering the power source-pump, considering the diversified working conditions of tank hydraulic jacking system actuators, sometimes the system requires large flow and low pressure; sometimes it requires small flow and high pressure.
Therefore, it is appropriate to choose a pressure-limiting variable pump, because the flow rate of this type of pump changes with the change of the system pressure. When the tank hydraulic jacking system pressure decreases, the flow rate is relatively large, which can satisfy the fast stroke of the actuator. When the tank hydraulic jacking system pressure increases, the flow rate decreases accordingly, which can meet the working stroke of the actuator. This can not only meet the working requirements of the actuator, but also make the power consumption more reasonable.
Maintain the tank hydraulic jacking system from a pressure perspective.
Second, when hydraulic oil flows through various types of hydraulic valves, there will inevitably be pressure loss and flow loss. This part of the energy loss occupies a large proportion of the total energy loss.
Therefore, reasonable selection of hydraulics and adjustment of pressure valve pressure are also an important aspect of reducing power loss. The flow valve is selected according to the flow adjustment range in the tank hydraulic jacking system and its minimum stable flow can meet the requirements of use. The pressure of the pressure valve should be as low as possible when the hydraulic equipment is working normally.
Maintain the tank hydraulic jacking system from the perspective of speed regulation.
Third, if the actuator has speed regulation requirements, when selecting a speed regulation loop, it is necessary to meet the speed regulation requirements while minimizing power loss. The speed control circuits of common tank hydraulic jacking system mainly include: throttle speed control circuit, volume speed control circuit, volume throttle speed control circuit.
The throttling speed control loop in the tank hydraulic jacking system has large power loss and good low-speed stability. The volumetric speed control circuit has neither overflow loss nor throttling loss, which has high efficiency but poor low-speed stability. If the tank hydraulic jacking system needs to meet both requirements at the same time, a volume throttling speed control circuit composed of a differential pressure variable pump and a throttle valve can be used, and the pressure difference between the two ends of the throttle valve should be as small as possible to reduce pressure loss.
In summary, a reasonable choice of hydraulic pressure is crucial. When the hydraulic oil flows in the pipeline, it will exhibit viscosity, and when the viscosity is too high, it will generate greater internal friction, causing the oil to heat up, and at the same time increase the resistance when the oil flows. When the viscosity is too low, it is easy to cause leakage, which will reduce the volumetric efficiency of the tank hydraulic jacking system.
Therefore, generally choose oil with suitable viscosity and good viscosity-temperature characteristics. In addition, when the oil flows in the pipeline, there are pressure loss and local pressure loss along the way. Therefore, when designing the tank hydraulic jacking system pipeline, the pipeline should be shortened as much as possible while reducing the number of bends.
The above are the recommended maintenance points to avoid the power loss of the oil tank hydraulic jacking system. However, there are many factors that affect the power loss of the tank hydraulic jacking system. Therefore, if specific maintenance is performed on the storage tank hydraulic jacking system, other requirements should be considered comprehensively!
Tank welding machine is the process of joining metal parts using various fusible alloys. The melting point of the solder is lower than that of the material to be soldered, so that the part will end the soldering through inter molecular contact on its surface without being melted.

What is the working principle of tank welding machines?
Tank welding machines can be divided into soft welding and hard welding. The temperature of soft welding is lower than 450℃, and the temperature of hard welding is higher than 450℃. Hard welding is usually used for metals such as silver, gold, steel, copper, and its welding point is much stronger than soft welding, and its shear strength is 20 to 30 times that of soft welding. The above two types of thermal connections usually use the term soldering, because in both cases molten solder is written into two elongated gaps between the clean and close solid metal surfaces of the device.
Tank welding machines ensure the continuity of the metal. On the one hand, two metals are connected by bolts or physical attachments to each other, showing a strong metal whole, but this connection is not continuous. Sometimes if there is an oxide insulating film on the metal surface, they may even Right or wrong physical contact.Another disadvantage of mechanical connection compared with welding is that the contact surface continues to oxidize, resulting in an increase in resistance. In addition, vibrations and other mechanical shocks can also loosen the joint. Welding eliminates these problems. The tank welding machines do not move relative to each other, the contact surface will not be oxidized, and the continuous conduction method can be maintained.
What is the purpose of using tank welding machines?
Tank welding machines welding is a process of fusion between two metals, mainly for the purpose of dissolving some of the metal in contact with the solder in the molten state, and the surface of the metal being welded often has a thin oxide film that cannot be dissolved by the solder. The flux is used to remove this oxide film. The tank welding machines welding process usually includes:
l 1) Melting of the flux to remove the oxide film on the surface of the welded metal;
l 2) Melting the solder makes the impure substances and lighter flux suspended in it float to the surface;
l 3) Some dissolve some metal connected with solder;
l 4) Cool and end the melting of metal and solder.
Through temperature changes, humidity, vibration, etc., even a bad solder joint can cause some or all of the system to lose control. There are countless welding points in the equipment, and the reliability of these welding points should even be higher than the equipment itself.
For the purpose of using tank welding machines, research in this area has led to the addition of knowledge of materials and their properties, and many developments have been made in the possible welding processes. Welding technology is an accompanying technology.
With the development of the electronics industry, more useful packaging technologies and smaller components will certainly continue to emerge. Welding technology will also continue to be developed to meet the needs of the electronics industry and environmental issues. This is why welding is becoming more and more professional for technology professors who work in the electronics industry today!
What are the application significance of tank welding machines?
The auxiliary equipment of the tank welding machines includes gas welding glasses to prevent the operator from being damaged by the ultraviolet, infrared or other rays generated by the welding arc or other welding energy, the mask to protect the eyes, face and neck of the welder during arc welding, white work clothes, welder gloves and protective guards.
l Energy efficient.
The energy saving of the electric welding machine is embodied in two aspects: energy saving at no load and energy saving at load. According to relevant statistics, in 2008, the demand for tank welding machines in the domestic welding industry was 890,000 units. If all electric welding machines are used, it can directly save 43,000 tons of copper, 64,000 tons of steel, and save 680 million KW.H of electricity. It saved 566,500 tons of coal, 10.34 million tons of water, and reduced 1,144,500 tons of CO2 emissions. It can be seen that vigorously promoting tank welding machines has huge economic and social benefits.
l Stable performance
Since the working frequency of the tank welding machines is above 20KHZ, it has a faster response speed, and the droplet transfer can be subdivided into multiple stages for control. For CO2 gas shielded welding, spatter can be greatly reduced. For pulsed melting pole MIG/MAG welding, the stability of jet transition can be effectively controlled, and the droplet transition and the movement of the wire feeding mechanism can be combined to further control the melting. During the dripping transition process, a good weld formation is obtained and the welding performance is stable. These are things that traditional rectifier welding machines cannot do.
l Centralized control
The tank welding machines uses a large number of digital controllers such as single-chip microcomputer, DSP, FPGA, etc., and realizes the network communication between multiple welding machines or the upper computer and the welding machine through Ethernet and field bus. It not only solves the problem of coordinated operation of multiple welding machines, and facilitates centralized control in the welding process, but also realizes the setting or monitoring of remote welding machine parameters, making remote fault diagnosis and maintenance of tank welding machines possible.

Metal pipe welding is an important part of aeroengine. Fuel, lubricating oil, air, oxygen and other working media in each system rely on metal pipes for transmission. Aviation engine pipeline parts have many types, large quantity, and high accuracy grade. Therefore, the requirements for manufacturing precision and quality are very high, and the requirements for manufacturing methods are getting higher and higher.
The main manufacturing method of metal conduit is tank welding machine welding. The welding of metal conduits of aero-engines mostly adopts manual argon arc welding, flame brazing, induction brazing, etc. The above-mentioned welding method is easy to operate, simple in equipment, low in cost, and low in requirement for a single welded pipe. Pipes, so it is widely used for pipe welding.
However, these welding methods are manual operations, which require very high skills for tank welders. Usually the weld formation is not ideal, and defects such as weld deviation, dents, weld leakage and incomplete welding will occur.
