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!

Specific structural characteristics of tank welding machines.

The basic structure of the exhaust pipe ring welding machine.The assembly of the automatic welding machine is mainly composed of a pulley guard, a transmission mechanism, an observation window, a platform, a guard, and a rotating clamping mechanism.

ACL-200's small automatic welding machine specifications.Aiming at the diameter of the duct in the aero-engine is usually within φ30mm, a small automatic ring welder with the model ACL-200 produced by the American MK company is selected. Tank welding machines are mainly used for butt welding of stainless steel, carbon steel, aluminum alloy and other pipes, and welding of pipelines and pipe joints. The welding range is the outer diameter of the catheter φ6～φ50mm.

Welding technical characteristics of tank welding machines.

Cleaning and tack welding before tank welding machines. Grind the inner and outer burrs of the tube end to make the tube end flush without burrs, and wipe it clean with alcohol. Manual tungsten argon arc welding is used for positioning.If tank welding machines use inappropriate positions, the position of the welding point will deviate from the neutral line of the welding butt surface.

Because the shape of the girth welding seam is relatively regular, the tack welding point that deviates from the weld cannot be covered by the normal weld, resulting in tack welding The points are on the edge and outside of the weld, making the weld surface poorly formed. If the positioning method is adopted, this kind of situation can be effectively avoided!

Simple chain type hydraulic jacking system is composed of one-stage double-acting hydraulic cylinder, pulley block, load-bearing chain and oil way etc. Moveable pulley is used to enlarge chain stroke, i.e. traveling distance of the cylinder is 1/2 of lifting distance of the chain. It applies to inverted installation and construction of various large storage tanks (steel) and various storage tanks.

LYT-type simple chain type hydraulic jacking system includes the following models: LYT-120-2700, LYT-200-2700, and LYT-300-2700 etc. (those with special stroke need to be customized).

• What is the working principle of the simple chain type hydraulic jacking system?

• What are the advantages of simple chain type hydraulic jacking system?

What is the operation process of the simple chain type hydraulic jacking system?

LYT-type simple chain type hydraulic jacking system is used to firstly lift the tank roof and the top (first layer) siding of the tank. It's required to group weld tank siding when the lifting height of siding exceeds the second siding (the second layer from the top) by 30-50mm, and group weld the third layer (the third layer from the top to the bottom) of the tank after lifting again, lift successively, group weld the siding of the tank layer by layer, until the last layer of siding.

What is the working principle of the simple chain type hydraulic jacking system?

LYT-type simple chain type hydraulic jacking system is used for lifting. When oil enters the hydraulic jack, the movable pulley is pushed upward by pressing the piston, thus driving the load-bearing chain to lift the expansion ring. In this way, the whole tank (including tank roof) is lifted up, until it reaches the pre-set height (there is a voidance of the next layer of plate). The siding in this layer is surrounded for butt welding. After the positioning block is welded, hydraulic hoist returns and the lift tank falls back to the newly-surrounded siding. After welding of circular seam and vertical seam, the door-type card for fixing expansion ring is cut off and the expansion ring is released. In this way, the hoist returns and expansion ring falls to the Model of hydraulic pump station Tank volume Rated pressure Rated flow Power Control voltage of solenoid valve Motor drive rate YB-7.2 220L (700*550*580) 25Mpa 7.2L/min Three-phase Four-wire (380V) 220V 5.5KW YB-14.5 340L (750*650*650) 25Mpa 14.5L/min 220V 7.5KW Mode of LYT-type hoist Rated lifting capacity (KN) Hydraulic area (mm) Rated oil pressure (MPa) Piston stroke (mm) Chain stroke (mm) Cylinder safety equipment Reinforcement measures LYT-120-2700 120 11304 25 1500 2700 Double-direction oil-way hydraulic lock 2 adjustable pull rods LYT-200-2700 200 18859.6 25 1500 2700 Double-direction oil-way hydraulic lock 2 adjustable pull rods LYT-300-2700 300 25434 25 1500 2700 Double-direction oil-way hydraulic lock 2 adjustable pull rods bottom of tank siding. Then, the next circular plate is expanded and transfer rib plate, such as door-type card, is welded for lifting, and so forth. The group welded tank is lift, until group weld of the last layer of siding, so that the whole storage tank is installed with this inverted method.

What are the advantages of simple chain type hydraulic jacking system?

1. Simple chain type hydraulic jacking system is stable, safe and reliable. Due to the adoption of unified hydraulic control and single or partial (several) adjustment, the whole lifting process is relatively stable. The hoist is provided with synchronizing valve and hydraulic lock to prevent sliding and falling of the tank or heavy loads, which are caused by power failure and fracture of oil tube. Hydraulic lifting is stable, safe and reliable.

2. Construction quality is ensured. As the hoist is provided with synchronizer and adjustable function, lifting height can be controlled accurately. Due to above reasons, quality of the tank is ensured.

3. The simple chain type hydraulic jacking system is easy to operate. Construction environment is good and work efficiency is high.

4. The simple chain type hydraulic jacking system is well-adapted. As long as the number of hydraulic hoists is increased or decreased, the whole set of equipment can be applied to the inverted hydraulic lifting construction of large storage tanks with different volumes ranging from several thousand cubic meters to tens of thousands cubic meters.

5. The hydraulic pump station and the hydraulic hoist are placed in the tank for easy operation. Finally, a door-closing plate is reserved to move the equipment out of the storage tank, and the door-closing plate is group welded well.

6. The hydraulic pump station can be controlled singly or jointly, and has strong construction adaptability and excellent technical performance price ratio.

7. Short construction period, low cost and good economic benefit. Due to the high degree of modernization and the fast lifting speed of the complete set of equipment, it has low construction cost and good economic benefit. This technology is truly characterized with convenient and centralized control, simple operation, safety and reliability (no falling), accurate control of weld clearance and lifting height of heavy objects, which can ensure the quality of the project, save labor and reduce costs, and achieve remarkable economic benefits.
