The hydraulic storage tank lifting equipment adopts the working principle of the straight top of the hydraulic oil cylinder, which can lift the lifting work table to a certain height and complete the transportation of the goods, which greatly saves manpower. The application range of hydraulic storage tank lifting equipment lift is very wide. Warehouse workshop, supermarket logistics station, and home can be installed and used, the safety factor of hydraulic storage tank lifting equipment lift is relatively high.
What should we pay attention to before using the hydraulic storage tank lifting equipment?
What should be paid attention to during the use of hydraulic storage tank lifting equipment?
What are the steps of using hydraulic storage tank lifting equipment?
1) Before use, it is necessary to check whether all parts of the hydraulic storage tank lifting equipment are normal, mainly check whether the piston, joints, high-pressure hoses, etc. leak oil.
2) The regulations in the main parameters should be strictly followed during use, and super high overload should be avoided, otherwise, when the lifting height or lifting tonnage exceeds the regulations, serious oil leakage will occur at the top of the hydraulic cylinder.
3) If the oil in the manual hydraulic pump is insufficient, it is necessary to add fully filtered hydraulic oil to the pump before it can work.
1) The choice of the center of gravity of the heavy object should be moderate, the focus point of the hydraulic storage tank lifting equipment should be selected reasonably, and the bottom surface should be flat. At the same time, the soft and hard conditions of the ground should be considered, whether it should be lined with tough wood, and whether the placement should be stable, so as to prevent the load from sinking. or inclined.
2) After the hydraulic storage tank lifting equipment lifts the heavy object, the support should be used to support the heavy object in time.
3) If several hydraulic storage tank lifting equipment need to be lifted at the same time, in addition to the correct placement of the jacks, attention should be paid to the balanced load of each hydraulic storage tank lifting equipment, and attention should be paid to keep the lifting speed synchronized to prevent the objects being lifted from tilting danger occurs.
1) When using the hydraulic storage tank lifting equipment, first place the hydraulic cylinder, and then tighten the oil drain screw on the hydraulic pump to work. To make the piston rod descend, loosen the handwheel of the manual hydraulic pump in a counterclockwise direction slightly, the hydraulic cylinder is unloaded, and the piston rod gradually descends. Otherwise, it will be dangerous to descend too fast.
2) The detached hydraulic storage tank lifting equipment adopts a spring reset structure. After lifting, it can be quickly taken out, but the connected hose cannot be used to pull the jack.
3) Due to the small lifting stroke of the jack, the rated stroke should not be exceeded during use to avoid damage to the jack.
4) The violent vibration of the hydraulic storage tank lifting equipment should be avoided during use (such as hitting the workpiece with a hammer when the hydraulic storage tank lifting equipment is loaded).

The whole pipeline project is divided into solution of container pipe spool fabrication line, on-site prefabrication and on-site installation. Among them, the Solution of container pipe spool fabrication line is the first step of pipeline engineering, and its importance is self-evident.
What are the specific principles of the solution of container pipe spool fabrication line?
What is the definition of solution of container pipe spool fabrication line?
What are the precautions for the production of solution of container pipe spool fabrication line?
The main purpose of the solution of container pipe spool fabrication line is to reduce the amount of installation on site so as to improve the efficiency of supply and installation and improve the construction quality of the pipeline. The general principles are as follows:
1. Pipes made of special materials, such as Hastelloy, titanium and other precious metal materials, have high requirements for installation quality, especially for the installation environment and surface anti-pollution requirements of pipelines. It is difficult to meet the requirements.
2. Pipes between combined equipment, such as compressor unit system pipelines, are generally prefabricated in the factory by equipment manufacturers according to equipment positioning due to the high internal cleaning requirements of such pipelines.
3. Pipe sections with special structures, such as jacketed pipes with strict requirements and pipes with special structures inside the pipes, can be prefabricated by manufacturers with mechanical processing due to on-site prefabrication and limited processing capacity.
4. Pipes with lining, such as carbon steel lined PTFE pipes, these pipes will generally be prefabricated and lined directly by manufacturers with lining capabilities entrusted by the owner according to the design drawings, and a certain adjustment pipe section is reserved. Prefabricated and installed on site.
Definition of solution of container pipe spool fabrication line: The discharge and sectional design of the pipeline of the piping system, in the factory (workshop), after pipe bending, pipe fitting fabrication, beveling, welding, heat treatment, inspection, marking, cleaning, painting And protection and other processes, the process of manufacturing pipeline products. Among them, we can understand that the depth in the solution of container pipe spool fabrication line represents the ratio of the number of welding and inspection completed in the prefabrication plant to the total number of welding in the project, that is, the ratio of the number of prefabricated welds to the total number of welds, for reference!
solution of container pipe spool fabrication line is to connect the pipes in the workshop when the construction is not good or the weather is bad, and then lay them directly on the site. This can speed up the progress of the project. Prefabrication should pay attention to details such as size and angle. There is the safety issue of large prefabs in transit.

1. Adjust the operating vehicle
According to the width of the steel plate, adjust the height of the operating vehicle, so that the distance between the bottom edge of the wheel and the upper surface of the tray can reach the width of the steel plate. At this time, the upper limit of the tray is adjusted in the middle position, and the beam of the tray can also be adjusted accordingly in the construction according to the situation.After adjusting the operation car, be sure to insert the puncture pin of the column and tighten the screws to ensure the smooth operation of the car during walking
2. Power access
Make sure there is no short circuit in the operation car, place the welding power switch in the correct position of automatic welding, turn on the power, and close the main switch of the welding power supply.And test and debug the system is normal operation.
3. Clean the groove
The Angle grinder is used to clean up the oil and rust in the groove, remove burrs, splashes and solder spots on the groove surface. The lower vertical joints of the steel plate are ground to 100mm, and the contact points between the upper vertical joints and the transverse joints are handled well to make the bottom of the groove smooth and smooth, so as not to hinder the movement of the pallet along the steel plate.
4. Install the welding wire
Put the wire into the wire tray for fastening, and then cut off part of the bundled string.
A hose should be added between the welding wire plate and the welding gun to avoid electric leakage between the welding wire and the body.The pressing force of the straightening wheel should be small to avoid bending of the welding wire caused by excessive pressure.After the welding wire is inserted into the gun barrel, close the wire feeding pressing wheel and press the "wire feeding" button to send the welding wire out of the conductive nozzle for a length. At this time, all the binding ropes are cut open.The pressing degree of the pressing wheel should be appropriate. If it is too loose, it will cause the wire to slip. If it is too tight, it will cause the wire indentation to be too large, and the resistance will increase, leading to the instability of the welding arc.When the conductive tip is worn too much, it must be replaced in time, otherwise the conduction is not reliable, and it is easy to cause the welding arc instability.
5. Filling flux
The flux shall be dried with a special drying box, and the heating temperature shall be as per the requirements of the flux. After heating, the flux shall be kept warm to about 50℃.When the flux temperature is too high, it can not be loaded into the flux box, so as not to burn the flux pipe.Pay attention to clean the dust on the filter cover in the flux box to ensure the suction of recovery.
6. Adjust the torch
Adjust the position and Angle of the welding torch so that it is in the center of the supporting belt.Operator requires that the stretching length of the wire is 20-30mm, that is, the distance between the conductive tip of the welding gun and the steel plate. The Angle of the welding gun is generally about 25 degrees.
7. Adjust the flux transport and recovery system
Adjust and operate the roof wheel, so that the tray is separated from the steel plate. Adjust the supporting belt on the tray to about 15-20mm below the groove, and then remove the roof wheel from the steel plate, so that the supporting belt contacts the tank wall, and test the operation for about 1M to check whether it is in normal operation.Adjust the relative position of the conveying port and the welding gun to ensure that the welding flux can fully protect the welding point;Adjust the position of the recovery port to ensure that all unreacted flux can be recovered to the flux tray.
8. Check whether the welding power switch is correct, whether the ground wire contacts and conducts well, check whether the switch behind the operation box is in the "automatic" position, and close the welding power switch.
9. Adjust the wire does not contact the steel plate, open the wire feed pressing wheel, press the "start" button of welding, at this time the voltmeter is displayed, adjust the voltage to 35V, and adjust the current to make the wire feed wheel speed is appropriate, press the "stop" button.(This work is mainly to ensure that the arc is easy to start after welding, the welding current and arc voltage are stable and the arc is normal.)
Because the pipe spool fabrication line is very smart, pipe spools are used in almost all industrial applications. The specific part of the pipe spool fabrication line can be arranged in various sizes and shapes of the target application area. Therefore, the most common application areas of tubing can be divided into: household applications, industrial applications (factories), medical applications and construction applications.
Here is the content list:

The pipe spool fabrication line is a component that can be welded or assembled to each other to form the entire pipeline system. Before discussing the application of pipe spool fabrication line, it is best to start with the understanding that the pipe is a straight longitudinal pipe used to transport fluid.
However, spools are pipes with complex shapes composed of different sections. They are used for prefabricated parts produced by pipe spool fabrication line, including shot blasting machines, pipe cutting machines, beveling machines, pipe fitting machines, pipe welding machines and other equipment.
Use of pipe spool fabrication line
① Residential use: cold, hot water and heating for houses and villas.
② Public buildings: water supply and floor radiant heating for public buildings such as office buildings, markets, theaters, and military camps.
③ Transportation facilities: piping for airports, passenger stations, parking lots, garages, and highways.
④ For animals and plants: piping for zoos, botanical gardens, greenhouses, and chicken farms.
⑤ Sports facilities: cold and hot water pipes for swimming pools and saunas.
⑥ Sanitary use: piping for water supply pipes and hot water pipes.
⑦ Other: industrial water pipes.
Features of pipe spool fabrication line

⑫ Easy and fast construction
The pipe spool fabrication line is a component that can be welded or assembled to each other to form the entire pipeline system. In modern engineering applications, the pipe spool fabrication line is used to transport required materials almost anywhere.
Domestic applications: Most domestic applications use steel pipe systems because of their mechanical durability and high corrosion resistance. The material of the short tube is domestic (domestic) stainless steel. The entire piping system of the house consists of stainless steel pipes and spools.
Industrial applications: Energy and certain raw materials are transported through the use of complex spool systems. Factories usually produce by-products such as exhaust gas and liquids. These exhaust gases and liquids must be removed from the production area. Therefore, these substances can also be removed through the pipeline system. In industries where space constraints can cause difficulties, some complex spool systems are the first choice. In addition, extremely long pipeline systems are also used for energy (oil, natural gas, etc.) transportation. These extra-long pipe systems have spool sections of various sizes and shapes.
Medical applications: Simple pipe spool fabrication line are even used in surgical and dental applications. The biocompatibility of the tubing used is the most important criterion in medical applications. Therefore, compatible pipe spool fabrication lines are used for bone healing or medical processing applications.
Construction applications: Pipes are one of the most common areas of use. For high strength, the required pipe material is usually selected as steel. When the foundation of the building is too weak to support the building, steel pipes are used as the support element of the building. In some architectural works, only complex spool systems are used for construction. The pipe spool fabrication line is also used to build ships and refineries.
Pipe spool fabrication line components can be divided into large and small straight pipes and accessories. In addition, accessories can also be divided into flanges, tees and elbows. These different components are widely used for other needs.
The pipe spool fabrication line must meet some essential requirements to generate effective fluid flow. Therefore, the complex pipe spool fabrication line must have high flexibility, cycle life, pressure rating, chemical resistance and corrosion resistance.
For example, pipe spool fabrication lines are commonly used in oil refineries and crude oil transportation lines. The sharp bend of the pipeline will change the type of oil flow from laminar to turbulent. Therefore, the turbulence of oil may cause corrosion and corrosion of the system.
These corrosion problems can be identified from the horseshoe-shaped cracks. Since these crevices remove material from the surface, they can cause leakage in the pipe spool fabrication line and are harmful to oil pipelines. Therefore, for the required pipe spool fabrication line application, the correct selection of materials and components is essential to the safety of the system!If you want to know more about high-quality tank welding machine products, you can also contact us at any time.
