Manufacturing step:1.Laying-off；2.Fitting-up；3.Welding；4.Correcting；5.Paint spraying；6.Packing

I.Laying-off process

Laying-off is the processing of steel plates or sections into the parts or components required by the drawings.

1.    Steel plate laying-off: first is to find 90 degrees, and then draw the cutting range with a tape measure and powder line (according to the thickness of the plate plus cutting allowance), if you need to drill holes for drilling, if you need to open groove groove processing.

2.    Section laying-off: first find 90 degrees with seat ruler or bend ruler, and then cut the line with seat ruler or bend ruler (also add cutting allowance),if you need to drill holes for drilling, if you need to open groove groove processing.

3.    Splicing of remaining materials：Plate splicing and section splicing.

What are the precautions for hydraulic storage tank lifting equipment?

1) If the emptying phenomenon occurs during use, you can first loosen the oil drain screw on the pump body, hit the vertical head of the pump body down a few times, and then tighten the oil drain screw, you can continue to use the hydraulic storage tank lifting equipment.

2) When using, do not add partial load or overload, so as to avoid the danger of hydraulic storage tank lifting equipment damage. When there is a load, do not remove the quick connector to avoid accidents and damage to the parts.

What should I do if the platform of the hydraulic storage tank lifting equipment lift cannot be lowered?

When using hydraulic storage tank lifting equipment lift, sometimes the lifting platform cannot be lowered. The solution to the hydraulic storage tank lifting equipment lift not being lowered depends on the situation:

1. The drop valve fails,

Troubleshooting method: In the case of pressing the down button, check whether the down valve has electricity. If there is no electricity, try to eliminate it; if there is electricity, then eliminate the failure of the down valve itself and replace the drop valve.

2. The deceleration control valve is out of balance

Remedy: Adjust the descending speed control valve, if the adjustment is invalid, you need to replace the new valve.

What is the working process of hydraulic storage tank lifting equipment?

When the hydraulic storage tank lifting equipment is stretched, the front and rear oil nozzles are opened, and oil is supplied from the rear oil nozzle to the tensioning working oil chamber, and the cylinder body of the tensioning cylinder moves backward. Since the cylinder cable is anchored on the tool anchor at the top of the jack, the hydraulic storage tank lifting equipment stretches the steel cable through the tool. When the wire rope is stretched to the required length, close the rear oil nipple, and feed oil from the front oil nipple into the top pressure cylinder, so that the top pressure cylinder piston moves forward to support the anchor plug, and the anchor plug is pressed into the anchor ring. Thus, anchoring the cable. Open the rear oil nozzle and continue to feed oil from the front oil nozzle. At this time, the tension cylinder moves forward and the oil in the cylinder returns. Finally, open the front oil nozzle to make the oil in the top pressure cylinder return, and the top pressure piston returns to its original position due to the action of the return spring.

This paper will mainly introduce the unfixing holding-latch hydraulic jack, Hydraulic jack is one of the key products of WINCOO ENGINEERING CO.,LTD.

Here is the content list:

• What are the characteristics of unfixing holding-latch hydraulic jack?

• What are the possible faults and solutions in use?

What is the working principle of unfixing holding-latch hydraulic jack?

Hydraulic lifting device (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 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.

What are the characteristics of unfixing holding-latch hydraulic jack?

1.Hydraulic lifting is stable, safe and reliable. The system adopts uniform control and single or partial (several) adjustment can be realized, so the lifting process is relatively stable. Characteristics of unfixing jack determine its good self-locking performance, without tank or heavy object gliding or falling due to power outage, which ensures safe and reliable hydraulic lifting.

2.Construction quality is guaranteed. Lifting height can be precisely controlled because of adjustable function (slightly descending). Welding quality if rank is guaranteed for the reasons given above.

3. Equipment is easy for operation with good working environment and efficiency.

4. The equipment has good adaptability. This set of equipment is applicable to hydraulic lifting of large-scale storage tanks with various volumes ranging from tens of thousands of cubic meters only by regulating hydraulic hoist (unfixing jack, hoisting frame, lifting rod, etc.)

5. Hydraulic pump station can be arranged at proper position as per actual working conditions. For large scale storage tanks, hydraulic pump station can be placed inside the tank, outside the tank or space between two tanks (when one pump station controls two tanks installation) for construction control.

6. Hydraulic pump station has manual and automatic controls with apparent features as strong adaptability and good technical performance price ratio.

7.Short construction period, low cost and good economic returns. Due to high modernization of package unit and fast lifting speed, the unit has low construction cost and good economic returns. The techniques has such advantages as easier for centralized control, convenient operation, safety and reliability (no falling), precise control of weld clearance and lifting height, which guarantees project quality, saves labor and reduces cost with remarkable economical benefit.

8.Unfixing jack is widely used in project installation due to its scientific structural design. The jack is composed of upper clamp, oil cylinder, lower clamp and support. Upper and lower clamps are equipped with self locking device. Upper clamp automatically locks lifting rod when oil cylinder ascends and lower clamp automatically loosens. During stroke return, upper clamp loosens and lower clamp locks lifting rod, thus, lifting rod cannot descend and lift heavy object to designated height step by step. The heavier the object is, the tighter the locking device locks. Heavy objects will not fall even during sudden power cut or oil pipe burst. This lifting mode is proven to be safe and efficient with low cost compared with pneumatic jack, big stroke jack and high altitude stranded wire lifting. These modes are not comparable to unfixing jack in terms of safety and practicability and it is the optimal product and installation for substitution. Unfixing jack is rapidly developed and applied in inversed lifting installation of storage tanks, power plant absorption tower and stack steel lining. This jack has slight descending function, which is convenient for plate to plate butt weld. As long as chaining fixing of support and lifting point are sufficient for bearing object load, the jack can lift object to designated place safely and efficiently.

Welding is a fabrication process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool, causing fusion.Welding is distinct from lower temperature techniques such as brazing and soldering, which do not melt the base metal (parent metal).. In addition to melting the base metal, a filler material is typically added to …
