Simple chain type hydraulic jacking system is composed of one-stage double-acting hydraulic cylinder, pulley block, load-bearing chain and oil way etc. Moveable pulley is used to enlarge chain stroke, i.e. traveling distance of the cylinder is 1/2 of lifting distance of the chain. It applies to inverted installation and construction of various large storage tanks (steel) and various storage tanks.
LYT-type simple chain type hydraulic jacking system includes the following models: LYT-120-2700, LYT-200-2700, and LYT-300-2700 etc. (those with special stroke need to be customized).
What is the operation process of the simple chain type hydraulic jacking system?
What is the working principle of the simple chain type hydraulic jacking system?
What are the advantages of simple chain type hydraulic jacking system?
LYT-type simple chain type hydraulic jacking system is used to firstly lift the tank roof and the top (first layer) siding of the tank. It's required to group weld tank siding when the lifting height of siding exceeds the second siding (the second layer from the top) by 30-50mm, and group weld the third layer (the third layer from the top to the bottom) of the tank after lifting again, lift successively, group weld the siding of the tank layer by layer, until the last layer of siding.
LYT-type simple chain type hydraulic jacking system is used for lifting. When oil enters the hydraulic jack, the movable pulley is pushed upward by pressing the piston, thus driving the load-bearing chain to lift the expansion ring. In this way, the whole tank (including tank roof) is lifted up, until it reaches the pre-set height (there is a voidance of the next layer of plate). The siding in this layer is surrounded for butt welding. After the positioning block is welded, hydraulic hoist returns and the lift tank falls back to the newly-surrounded siding. After welding of circular seam and vertical seam, the door-type card for fixing expansion ring is cut off and the expansion ring is released. In this way, the hoist returns and expansion ring falls to the Model of hydraulic pump station Tank volume Rated pressure Rated flow Power Control voltage of solenoid valve Motor drive rate YB-7.2 220L (700*550*580) 25Mpa 7.2L/min Three-phase Four-wire (380V) 220V 5.5KW YB-14.5 340L (750*650*650) 25Mpa 14.5L/min 220V 7.5KW Mode of LYT-type hoist Rated lifting capacity (KN) Hydraulic area (mm) Rated oil pressure (MPa) Piston stroke (mm) Chain stroke (mm) Cylinder safety equipment Reinforcement measures LYT-120-2700 120 11304 25 1500 2700 Double-direction oil-way hydraulic lock 2 adjustable pull rods LYT-200-2700 200 18859.6 25 1500 2700 Double-direction oil-way hydraulic lock 2 adjustable pull rods LYT-300-2700 300 25434 25 1500 2700 Double-direction oil-way hydraulic lock 2 adjustable pull rods bottom of tank siding. Then, the next circular plate is expanded and transfer rib plate, such as door-type card, is welded for lifting, and so forth. The group welded tank is lift, until group weld of the last layer of siding, so that the whole storage tank is installed with this inverted method.

Hydraulic storage tank lifting equipment is a jack that uses a plunger or a hydraulic cylinder as a rigid jacking member. It has compact structure, stable operation and self-locking function.
How to properly maintain the hydraulic storage tank lifting equipment?
What reasons may cause the hydraulic storage tank lifting equipment lift to fail?
How does hydraulic storage tank lifting equipment work?
1) The hydraulic storage tank lifting equipment uses oil as the medium, so the maintenance of the oil and the equipment must be done well to avoid blockage or oil leakage, which will affect the use effect.
2) For a new or long-established hydraulic storage tank lifting equipment, since there is a lot of air in the hydraulic cylinder, when it starts to use, the piston rod may have a small jump phenomenon, and the hydraulic storage tank lifting equipment can be reciprocated with no load. 2 to 3 times to remove the air in the cavity. The hydraulic storage tank lifting equipment that has been idle for a long time will harden due to the long-term non-working of the seal, which will affect the service life of the hydraulic jack. Therefore, when the hydraulic storage tank lifting equipment is not in use, it should be reciprocated 2 to 3 times a month with no load.
1. If the gear pump of the hydraulic storage tank lifting equipment lift is damaged, and the pumped oil has no pressure, it cannot be lifted, and the lift gear pump should be replaced.
2. The support valve or electromagnetic reversing valve of hydraulic storage tank lifting equipment lift fails to operate, and a new support valve or electromagnetic reversing valve needs to be replaced.
3. The manual pump and gear pump of the hydraulic storage tank lifting equipment lift leak oil. If the oil leak is serious, it will lead to insufficient power, and the sealing ring of the lifting oil pump needs to be replaced in time.
4. The circuit of hydraulic storage tank lifting equipment lift is open circuit. The hydraulic system is controlled by the circuit. If the circuit is short-circuited or open, it will also cause it to fail to lift. It is necessary to check the lift button contactor and fuse and other parts.
5. The check valve of the manual pump of the hydraulic storage tank lifting equipment lift is stuck and the return position fails. This kind of failure is more troublesome. The solution is to unscrew the oil pump valve port bolt, repair, clean, and replace the clean hydraulic oil.
The principle of hydraulic storage tank lifting equipment is based on Pascal's principle, that is, the pressure of the liquid is the same everywhere so that in a balanced system, the pressure exerted on the smaller piston is relatively small, and the pressure exerted on the larger piston is also relatively large to keep the liquid still.
Therefore, the hydraulic storage tank lifting equipment can obtain different pressures on different ends through the transmission of the liquid, so that a transformation purpose can be achieved. The hydraulic storage tank lifting equipment we see commonly uses this principle to achieve force transmission.
WINCOO ENGINEERING CO., LTD has committed to providing the most suitable hydraulic storage tank lifting equipment at a reasonable price, and whatever it takes to satisfy the customer’s needs.
