Tank hydraulic jacking system is mainly a closed or meshed hoistway enclosed by buildings or light steel structures and hydraulically driven cylinders to lift the platform. So what are the advantages and disadvantages of the use of tank hydraulic jacking system?
Here is the content list:
l What are the components of the tank hydraulic jacking system?
l What are the advantages and disadvantages of tank hydraulic jacking system?
l How to deal with the shortcomings of tank hydraulic jacking system?
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.
l Advantages of tank hydraulic jacking system:
1. Small size and light weight
2. Large rigidity, high precision and fast response
3. Large driving force, suitable for heavy load direct drive
4. Wide speed range and various speed control methods
5. Self-lubricating, self-cooling and long life
6. Easy to realize security protection
l Disadvantages of tank hydraulic jacking system:
1. Poor anti-contamination ability of working fluid
2. Sensitive to temperature changes
3. There is a hidden danger of leakage
4. Difficult to manufacture and high cost
5. It is not suitable for long-distance transmission and requires hydraulic energy
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.
