A complete tank hydraulic jacking system consists of five parts, namely power components, executive components, control components, auxiliary components (accessories) and hydraulic oil.
The function of the power element is to convert the mechanical energy of the prime mover into the pressure energy of the liquid, which refers to the oil pump in the hydraulic system, which provides power to the entire hydraulic system. The structure of hydraulic pumps generally includes gear pumps, vane pumps, plunger pumps and screw pumps.
The function of the executive components (such as hydraulic cylinders and hydraulic motors) is to convert the pressure energy of the liquid into mechanical energy, and drive the load for linear reciprocating motion or rotary motion.
Auxiliary components include fuel tanks, oil filters, coolers, heaters, accumulators, oil pipes and pipe joints, sealing rings, quick-change joints, high-pressure ball valves, hose assemblies, pressure measuring joints, pressure gauges, oil level gauges, oil Thermometer etc.
The tank hydraulic jacking system consists of hydraulic pump station, oil cylinder, steel wire and stroke, which is easy to install and operate. The tank hydraulic jacking system uses PLC central control for lifting. Each power unit is equipped with an auxiliary balance device to ensure the accuracy of simultaneous lifting. In addition, the hydraulic lifting pump station has two operating modes: auxiliary manual control and control. The cylinder can be adjusted to lift individually, or it can be combined with other lifting units into a group, or it can be integrated with multiple lifts to achieve higher accuracy and better welding results!
On the other hand, all cylinders of the tank hydraulic jacking system are equipped with safety valves. It can be automatically locked, even in the event of a power failure, a rupture of the high-pressure hose, or a rupture, it can prevent the cylinder/fuel tank from falling. The number of tank hydraulic jacking system can be adjusted according to the tank size and weight high efficiency, it only takes 15 minutes for each rise or fall. It can be used in conjunction with our company's slot welding machine, which can greatly reduce labor costs and reduce construction time.

The tank hydraulic jacking system is generally flushed before it is officially put into operation. The purpose of flushing is to remove contaminants, metal chips, fiber compounds, iron cores, etc. remaining in the system. During the first two hours of work, even if the tank hydraulic jacking system is not completely damaged, It will also cause a series of failures. Therefore, the oil circuit of the tank hydraulic jacking system should be cleaned according to the following steps:
l 1) Clean the oil tank with an easy-to-dry cleaning solvent, and then use filtered air to remove solvent residues.
l 2) Clean all pipelines of the tank hydraulic jacking system. In some cases, the pipelines and joints need to be immersed.
l 3) Install oil filter in the pipeline to protect the oil supply pipeline and pressure pipeline of the valve.
l 4) Install a flushing plate on the current collector to replace precision valves, such as electro-hydraulic servo valves.
l 5) Check whether all pipelines are of appropriate size and connected correctly.
If it is found that the oil filter is clogged, change the oil filter immediately. The flushing cycle is determined by the structure of the tank hydraulic jacking system and the degree of system pollution. If the sample of the filter medium has no or few foreign pollutants, install a new oil filter and unload it. Flush the plate and install the valve to work! Planned maintenance: Establish a regular system maintenance system, and suggestions for better maintenance of the tank hydraulic jacking system are as follows:
l 1) Check and replace the oil at most 500 hours or three months.
l 2) Flush the imported oil filter of the oil pump regularly.
l 3) Check whether the hydraulic oil is contaminated by acidification or other pollutants. The smell of the hydraulic oil can roughly identify whether it has deteriorated.
l 4) Repair leaks in the tank hydraulic jacking system.
l 5) Ensure that no foreign particles enter the fuel tank from the vent cap of the fuel tank, the plug seat of the oil filter, the sealing gasket of the oil return line and other openings of the fuel tank.

It is not easy to maintain pipe spool fabrication line. Whether it is used in the oil and gas industry, power plants, chemical plants or other infrastructure projects, the pipe spool fabrication line usually contains hundreds of components and thousands of processing steps. Therefore, it is very important to maintain the pipe spool fabrication line.
Here is the content list:
l Line maintenance
l Pipeline repair
l The advantages of choosing WINCOO to repair and maintain the tube shaft production line.
The maintenance of the pipe spool fabrication line includes inspection of pipeline corrosion and anti-corrosion; inspection of pipelines for oil leaks; inspection of valves along the line; inspection of the loss of hydraulic structures and coatings along the line; inspection of signs of damage, etc. Once the pipeline line and equipment are found to be faulty, the pipe spool fabrication line should be repaired or updated in time.
Due to the long line of the pipe spool fabrication line, it may be damaged by man-made and natural disasters at any time. Therefore, it is necessary to conduct line inspection and maintenance of the pipe spool fabrication line frequently. In addition, there is also a dedicated pipeline maintenance team equipped with necessary mobile equipment, earth moving equipment, welding and blocking equipment, and communication tools, so that they can be prepared for emergency repairs at any time.
l Pipe spool fabrication line anti-corrosion inspection
Routine pipe spool fabrication line anti-corrosion inspections include: regularly testing the protection potential along the pipeline; using an anti-corrosion layer detector to check the integrity of the pipe's anti-corrosion layer on the ground. The inspection of corrosion in the old pipeline is a complicated task, and it is usually carried out with a cup-type pipe cleaner with a testing instrument.
The testing equipment of the pipe spool fabrication line includes a magnetic flaw detector to detect internal corrosion and an ultrasonic thickness gauge to detect the thickness of the pipe spool fabrication line. The running distance is calculated by the number of revolutions of the support wheel, and all the tested parameters are converted into signals and recorded on the tape. After the inspection, the tape is interpreted by the computer, which can indicate the corrosion degree and location of the pipeline.
l Pipe spool fabrication line oil leakage inspection
Mainly rely on line inspectors to inspect the pipe spool fabrication line. In order to ensure the safety of residents and enterprises along the route, all countries have formulated oil and gas pipeline safety technical specifications, which are strictly supervised and implemented by government departments. If leakage occurs in the pipe spool fabrication line, report it to the competent authority immediately and check the cause of the accident on site.
Heavy rains and floods will cause soil erosion on the pipe spool fabrication line and damage to the embankment, resulting in exposed, suspended or even broken underwater pipelines. These situations are mainly discovered by line inspectors. Line patrol personnel usually walk on the ground or fly in the air to patrol the line. The maintenance work of the pipe spool fabrication line must be implemented in accordance with the detailed line engineering as-built drawing!
The most prominent part of the maintenance of the pipe spool fabrication line is the handling of large accidents such as leak repair and pipe replacement. If the leak is caused by corrosion and perforation, you can use a fixture to plug the leak on the pipe and then perform repair welding.
If the pipe spool fabrication line is severely damaged or deformed, the pipe must be removed and replaced with a new pipe section. The oil and gas leaked when the pipe is cut off can easily cause a fire. When cutting off the pipeline at low places, it is necessary to prevent a large amount of oil and gas from leaking. Mechanical plugging devices are often used to plug the pipelines, and emergency repair operations are carried out without stopping the transportation.
The mechanical plugging method is to open a hole on the upstream and downstream of the pipe section to be replaced, and insert a plug with a cup into each hole to isolate the oil or gas at both ends, and then drain the oil in the damaged pipe section. Or gas, cut off the pipe section with a mechanical cutter, then insert two pigging balls into the cuts at both ends, and fill the gap between the pigging balls and the plug with nitrogen to prevent explosion during welding.
Put the equipped new pipe spool fabrication line in place, align and weld. After welding, lift the occluder out of the pipe and close the opening to complete the plugging and pipe replacement work. After the pipe spool fabrication line is repaired and operated, two pig balls will be recovered in the pig receiver tube of the downstream station. When plugging and replacing a pipe section, the bypass pipe can be drawn out before plugging to ensure uninterrupted pipe spool fabrication line delivery during the entire pipe replacement process.
