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 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 lifted by N sets of 5T-3M model electric chain hoist, 5 tons of electric chain hoist can be used up to 60% of its max tonnage, that is, no more than 3 tons.The max stroke of the electric chain hoist is 3 meter(length can be customized).

Equipment operation steps:

1.First,making the top first circle plate of the tank body on the bottom plate;Then install the expansion ring on the first ring plate(The bottom of the expansion ring is about 200mm away from the bottom edge of the first ring plate);Finally, tighten the ring on the first ring plate with the screw jack.

2.Installed the lifting column on the inner side of the tank 400mm away from the tank wall and N lifting columns are evenly arranged on the inner side of the whole tank.Then the upper end of the column and the bottom plate of the tank are fixed with two pull rods as triangular stay support.

3.Using the pull rod to pull the two adjacent lifting columns to form an integral circle. And a lifting lug is welded on the expansion ring corresponding to the lifting column, the baffle is welded on the tank wall at the upper end of the expansion ring to block the ring.

4.Hang the electric chain hoist on the lifting lug at the top of the column and Hook the hook of the electric hoist on the lifting lug of the expansion ring.Then install all the electric hoist in order and connect the power supply of all electric hoist to the main control board(The main control board can control each electric hoist separately, and can also control all electric hoist centrally and synchronously).

Note:Switch on the total power supply, then pre-tighten each electric hoist, check whether the receiving force of all electric hoist is uniform and check whether all lifting points are normal.If everything is normal, it can be lifted.

5.Switch the main control board to the centralized control and switch on the overall rising button, so that all electric hoist will rise synchronously.In the process of lifting, if some electric hoist fails to work, the master control board shall be converted to separate control. After re-tightening the loose electric hoist, lift it as a whole until it reaches the specified height. Finally, adjust the lifting height to be consistent through separate adjustment.

6.Make the second ring plate, after welding the vertical seam and block, drop all the electric hoist as a whole, and let the first ring plate fall back to the second ring plate, so that the overall lifting of the first ring plate is completed.

7.After the girth seam welding is completed, loosen the expansion ring.And lower the rising ring to the designated height at the bottom of the second ring plate with the electric hoist, and then carry out the preparation for the next lifting.

What are the advantages of orbital welding machine?

The application range of the orbital welding machine is greatly increased, the structure is simple, the cost is low, the purchase cost of the user can be reduced, the installation operation is convenient, the auxiliary operation time is short, and the work efficiency is high. The support flexible rail includes two parallel rails, and each rail includes a strip substrate.

What are the technical requirements when using the orbital welding machine?

Orbital welding machine shall not be used if the rail has the following conditions:

1. The rail is judged to have internal damage or serious surface injury.

2. The depth of the pit after the top surface of the rail head is damaged and polished:

Weld repair on the line exceeds 8 mm;

Solder repairs over 10 mm outside the line.

3. For scratches, spalling, falling blocks and welding joint wear, low collapse, etc. on the top surface of the rail head, the allowable length of welding repair shall meet the following requirements:

For rail joints (including welded joints) wear and low collapse, the allowable one-time welding repair length is 300 mm, and if the damaged length exceeds 300 mm, it should be divided into two sections for welding repair.

For defects and damages such as scratches, spalling and falling blocks on the top surface of the rail head, the length of one welding repair is allowed to be 200 mm. If the length exceeds 200 mm, it should be divided into two sections for welding repair.

When the rail joints are worn, slumped, scratched and peeled off at the same time, the scratches and peeled off blocks should be dealt with first.

What are the fields of application of orbital welding machines?

At present, the development of railways is mainly in the direction of high-speed passenger cars, subway passenger cars, light rail cars, high-speed heavy-duty trucks, etc. In order to achieve these needs, it is necessary to reduce the weight of trains. A common practice now is to use aluminum alloy materials in the manufacturing process of passenger cars. Because aluminum alloy materials have the characteristics of light weight, corrosion resistance, smooth appearance, complex curved surfaces, and high specific strength, they can effectively reduce the resistance and quality of passenger cars, and increase the overload. In order to effectively improve the processing efficiency of aluminum alloy materials, it is necessary to change the traditional processing method and use the welding technology of the orbital welding machine for processing and manufacturing.
