Common problems when using tank hydraulic jacking system.
Reasons for leakage of tank hydraulic jacking system.
(1) Caused by defects in design and manufacturing
(2) Impact and vibration cause loose pipe joints
(3) Mutual wear of dynamic seals and matching parts (especially hydraulic cylinders)
(4) The oil temperature is too high and the rubber seal is incompatible with the hydraulic oil and deteriorated.
Combining the above problems, talk about the measures to control the leakage of tank hydraulic jacking system.
l Solution 1: Design and manufacturing defect solutions
The selection of external components of tank hydraulic jacking system often plays a decisive role in the leakage of hydraulic system. This determines that in the improvement of tank hydraulic jacking system, our technicians should carefully choose the cylinders, pumps, valves, seals, hydraulic accessories, etc. based on the principle of choosing the best among the best and choosing the cheap.
① Reasonably design the mounting surface and sealing surface of the tank hydraulic jacking system. When the valve block or pipeline is fixed on the mounting surface, in order to obtain a satisfactory initial seal and prevent the seal from being pushed out of the groove and being worn.
② The installation surface of the tank hydraulic jacking system should be straight and the sealing surface should be finished. The surface roughness should reach 0.8μm and the flatness should reach 0.01/100mm. The surface must not have radial scratches, and the pre-tightening force of the connecting screw must be large enough to prevent surface separation.
③ During the manufacturing and transportation of tank hydraulic jacking system, it is necessary to prevent the key surface from bumping and scratching. At the same time, the assembly and debugging process must be strictly monitored to ensure the quality of assembly.
④ Do not be taken lightly about the leakage of some tank hydraulic jacking system, and must be eliminated.
l Option 2: Reduce shock and vibration
In order to reduce the leakage of tank hydraulic jacking system caused by the loosening of pipe joints subjected to shock and vibration, the following measures can be taken:
① Use shock-absorbing brackets to fix all pipes to absorb shock and vibration;
② Use low-impact valve or accumulator to reduce the impact;
③ Properly arrange pressure control valves to protect all components of the tank hydraulic jacking system;
④ Minimize the number of pipe joints used, and try to use welding to connect pipe joints;
⑤ Use straight threaded joints, tee joints and elbows instead of tapered pipe threaded joints;
⑥ Try to replace each piping with oil return block;
⑦ For the highest pressure used by the tank hydraulic jacking system, specify the bolt torque and plug torque during installation to prevent the joint surface and seal from being eaten away;
⑧ Install the pipe joints of the tank hydraulic jacking system correctly.
l Option 3: Reduce the wear of dynamic seals
Most of the dynamic seals have been precisely designed. If the dynamic seals are qualified, installed correctly, and used reasonably, they can guarantee a long-term relatively leak-free work. From the perspective of tank hydraulic jacking system design, designers can take the following measures to extend the life of dynamic seals:
① Eliminate the side load on the piston rod and drive shaft seal;
② Use dust ring, protective cover and rubber sleeve to protect the piston rod to prevent abrasives, dust and other impurities from entering;
③ Design and select a suitable filter device and a fuel tank that is easy to clean to prevent dust from accumulating in the oil;
④ Keep the speed of the piston rod and shaft as low as possible.
Matters needing attention when using tank hydraulic jacking system.
First of all, the requirements for static seals,tank hydraulic jacking system static seals prevent oil leakage between rigid fixed surfaces. Reasonably design the size and tolerance of the seal groove, so that the installed seal will be deformed to a certain extrusion so as to fill the microscopic depression of the mating surface and increase the internal stress of the seal to be higher than the pressure to be sealed.
It should be noted that when the rigidity of the part or the pre-tightening force of the bolt is not large enough, the mating surface will separate under the action of the oil pressure, causing a gap or increasing the gap that may exist from the beginning because the sealing surface is not flat enough. As the mating surface moves, the static seal becomes a dynamic seal. Rough mating surfaces will wear the seal, and the fluctuating gap will eat away at the edge of the seal.
In addition, control the oil temperature to prevent deterioration of the seal. Premature deterioration of the seal may be caused by many factors. An important factor is the high oil temperature. Each time the temperature rises by 10°C, the seal life will be halved. Therefore, a reasonable design of an efficient tank hydraulic jacking system or a forced cooling device should be provided to keep the optimal oil temperature below 65°C.
Among them, engineering machinery of tank hydraulic jacking system must not exceed 80°C, and hydraulic oil and seal types and materials should be selected according to the operating instructions or relevant manuals to solve compatibility problems and extend the service life of seals.

In this article, we will explore more details about pipe spool fabrication line.
Here is the content list:
l What is the pipe processing workshop of the pipe spool fabrication line?
l What are the pipe manufacturing specifications of the pipe spool fabrication line?
l What are the steps of pipe spool fabrication line?
The pipe spool fabrication line workshop is basically a workshop, and all pipe spool fabrication line are developed here. Generally, all pipe spool fabrication lines used for spool preparation are performed in the workshop using skilled pipe manufacturers.
In large-scale pipe manufacturing plants, pipe spool fabrication line is the best economical way to reduce on-site installation costs. The pipe manufacturing workshop provides all equipment, tools and manpower, and the quality of the pipe shaft is high.
The pipe spool fabrication line specification is an engineering document that provides all the guidelines that the reel manufacturer should follow. The pipe spool fabrication line provides the minimum requirements for preparing detailed workshop drawings and manufacturing, as well as the requirements for inspection and testing. It lists all applicable codes and standards.
The pipe manufacturing process of pipe spool fabrication line requires the assembly of pipes and pipe fittings according to the spool diagram. The pipe spool fabrication line manufacturer must consider the size of the components, because transportation may become a problem. In this case, sub-components are an effective way to transport large projects. Follow the steps below to complete the pipeline manufacturing:
l Marking and cutting:
According to the requirements of the design drawings, marking should be carried out and confirmed by the relevant supervisor before cutting. Pipe cutting is usually performed as follows:
① Carbon steel pipe-through gas cutting and grinding.
② Alloy steel pipe-cut by grinding or flammable.
③ Stainless steel tube-by grinding or plasma cutting.
Use dye imprinting, paint marking or marking to transfer the heat of the pipe to the cut piece before cutting the pipe spool fabrication line.
l Final preparation:
In the next step, final preparation (chamfering) and assembly are carried out in accordance with the approved specifications and WPS.
l Welded pipes:
Extra precautions must be taken to ensure that the longitudinal seams on the connecting pipe spool fabrication lines are not aligned in the butt weld. The spacing between the seams must be at least 100 mm apart, and branch connections should also be cleared. Take care to ensure that the longitudinal seams are not resting on the steel structure.
l Welded pipes and fittings:
The pipe spool fabrication line and fittings used for assembling are then placed on a temporary pipe bed and properly fixed and supported. Next, check the quality assembly of the device. After receiving the inspection gap, the joints will be welded by qualified welders.
l Detailed information marking:
Use metal paint marks to mark various detailed information near the joints: pipeline number, component heating number, joint number, assembly inspection signature, welder number, visual inspection signature and welding date. The spool number of the pipeline is marked with a paint mark, and an aluminum label is tied to the spool.
l Heat treatment:
According to the specific requirements of the project, preheating and PWHT will be carried out in the workshop or on-site.The pipe spool fabrication line is then transferred from the pipe workshop to the laying area.
Perform non-destructive inspection according to the requirements of project specifications or guidelines. After receiving the NDT permission, the spool will be released for installation/painting, with a release notice. Spools rejected in the NDT process are identified with yellow and black labels and sent for repair. NDT has tested the repaired welding area again as needed.
After painting, the quality control will be inspected on site and recorded in the prescribed format. After the paint inspection, loosen the spool for installation.
l Manufacture of stainless steel pipe:
The manufacture of pipe spool fabrication line is usually carried out in the workshop, and the isolation area is carbon steel and alloy steel. Equipment and tools used for CS manufacturing shall not be used for SS. SS tools must be distinguished by marking only "For Stainless Steel". For stainless steel materials, stainless steel tools will be used for grinding, brushing and clamping.
For protection and temporary storage until installation, all flange convex surfaces of the completed pipe section are equipped with plywood shutters, and the end of the valve core should be equipped with an appropriate cover.If you want to know more about high-quality tank welding machine products, you can also contact us at any time.
