Use H beam straightening and welding machine to weld H-beam distortion treatment method: If the H-beam flange has out-of-tolerance torsion, it means that the H-beam has distortion that needs to be corrected. The upper flange of the H-beam can be inspected with a level ruler. First, adjust and ensure that the level of most of the flanges of the H-beam body is within the deviation range, measure the excess part and correct it accordingly. Measurement method: The frame level is placed in the width direction of the detection flange, and the feeler gauge is used to pad the lower side to the level, and the reading of the feeler gauge can be used to know how much the twist is. Or use a spirit level to directly measure two points on the width edge of the flange with a ruler, and the difference between the readings is the torsion value.

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 operation process of the simple chain type hydraulic jacking system?
What is the working principle of the simple chain type hydraulic jacking system?
What are the advantages of 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.
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.
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.

The pipe spool fabrication line has unique structure, high degree of automation, convenient operation, stable and reliable continuous production. The pipes produced by this pipe spool fabrication line have moderate rigidity, strength, good flexibility, creep resistance, environmental stress cracking resistance and good thermal welding performance, and have become the first choice for urban gas pipelines and outdoor water supply pipes. However, there are still some problems when using the pipe spool fabrication line.
Here is the content list:
l Failure of the production line and corresponding measures.
l Computer system failure and corresponding measures.
l Pipe spool fabrication line failure and corresponding measures.
l The outer surface of the pipe spool fabrication line is rough
① Adjust the pipe spool fabrication line of process temperature: reduce the cooling water temperature, the best cooling water temperature of the PE pipe is 20~25℃
② Check whether the waterway is blocked or the water pressure is insufficient;
③ Check whether the heating ring of the barrel, head, etc. is damaged;
④ Adjust the water flow of the sizing sleeve;
⑤ Please consult the raw material supplier for the raw material parameters of the batch;
⑥ Check the mold core temperature, if it is higher than the die temperature, reduce the mold core temperature;
⑦ Clean the mold;
l Grooves appear on the outer surface of the plastic pipe
① Adjust the water outlet pressure of the sizing sleeve, and balance the water output;
② Adjust the nozzle angle in the vacuum forming box to evenly cool the pipeline;
③ Check the mold, sizing sleeve, cutting machine and other hardware for debris and burrs;
l There is a jitter ring inside the pipe spool fabrication line
① Adjust the water outlet of the sizing sleeve to make it even.
② Adjust the vacuum degree of the second chamber so that the vacuum degree of the rear chamber is slightly higher than that of the front chamber;
③ Check whether the vacuum seal is too tight;
④ Check whether the tractor is shaking;
⑤ Check whether the host output is even;
l The outer diameter of the pipe spool fabrication line is out of tolerance
① Adjust the vacuum to change the size of the outer circle;
② Adjust the traction speed to change the outer ring size;
③ Correct the size of the inner hole of the sizing sleeve;
l Uneven wall thickness of pipe spool fabrication line
① Adjust the wall thickness of the mold; adjust the nozzle angle in the vacuum setting machine and spray box to uniformly cool the pipeline.
② Adjust the water outlet of the sizing sleeve to make it even.
③ Disassemble the mold, check whether the screws in the mold are loose, and then tighten it again;
Computer system failure
When the computer is turned on or running, pipe spool fabrication line is not allowed to enter the test state.
l Problem 1: The tensile strength and toughness are poor. The tensile strength curve of pipe spool fabrication line should have obvious yield strength and greater elongation, while poor plastic pipes are usually fragile, low elongation and easy to break.
l Problem 2: Poor impact resistance. According to the GB/T5836.1-92 standard, the drop hammer impact test was tested. After years of testing, it was found that the pass rate was only less than 50%, and many pipe spool fabrication line were even damaged by 10 times.
l Problem 3: The softening temperature is low and it is easy to deform after being heated. It is shown in the test performance, that is, the Vicat softening temperature is relatively low (less than 79). Some manufacturers only increase the amount of filler during the compounding process to increase the softening temperature.
This can indeed increase the softening temperature, but will greatly reduce the other properties of the pipe, especially impact resistance, tensile strength and toughness. Therefore, in order to increase the softening temperature without reducing or seldom reducing other properties, attention must be paid to the selection of additives, the ratio of raw materials, the production process and the production machinery, Can not be taken lightly.
Pipe spool fabrication line is tested in accordance with the national standard GB/T10002.1-1996, and its hydraulic inspection performance standard value requirements are relatively high, which puts forward high requirements for enterprises that produce pipe spool fabrication line. The eccentricity problem is one of the common plastic pipe problems, which will result in large uneven wall thickness of the produced plastic pipes, which not only causes waste of raw materials, but also makes it difficult for the water pressure test performance to meet the requirements.
The operation of the pipe spool fabrication line has a great impact. Therefore, this requires manufacturers not only to match the materials well, but also to install online testing equipment so that qualified companies can adjust the size deviation of the plastic pipe at any time.
