Product name: synchronous hydraulic jack
product description:
Application of synchronous control:
The jacking of the bridge. Tunnel jacking (pipe jacking);
Installation and commissioning of heavy equipment;
Shipbuilding hull lifting, propeller loading and unloading, and main engine installation;
Jacking up a building and translating existing buildings;
Jacking and measurement of oil well platforms;
Synchronous hydraulic jacks move horizontally, etc.
Product details
Synchronous hydraulic jack selection 1. Specification: one for two, one for four, one for six, one for eight, one for ten, one for twelve, one for fourteen, one for sixteen, etc. Two, jack tonnage: 10t, 20t, 30t, 50t, 100t, 150t, 200t, 320t, 500t.
3. Pumping station: 1.1Kw, 1.5Kw, 2.2Kw, 4Kw, 5.5Kw, 7.5Kw, 13Kw
Fourth, the use of synchronous hydraulic jack:
1. If the amount of oil in the pump body is insufficient, you need to add working oil (46 # engine oil) to the pump to work.
2. Estimate the lifting weight and avoid overloading.
3. Determine the center of gravity of the lifting object and select the point of force for the jack. At the same time, you must consider whether the softness and hardness of the ground is lined with tough wood to avoid the risk of falling when lifting.
4. After the jack lifts the heavy object, the heavy object should be supported with tough wood in time. It is forbidden to use the jack as a support, so as to avoid unbalanced load and the risk of falling. 5. When in use, first connect the quick connector of the manual pump to the top, then select the position, and tighten the oil drain screw on the oil pump to work. Loosen the drain screw and unload the oil cylinder.
6. For electric pump, please refer to the electric manual
Fifth, synchronous hydraulic jack precautions:
a) If runaway occurs during use, first loosen the oil drain screw on the pump body, lift the pump body upright and hit it downwards a few times, then tighten the oil drain screw to continue using.
b) When there is a load, do not remove the quick connector to avoid accidents and damage to the parts.
c) The machine uses oil as the medium, and the maintenance of the oil and the machine must be done to prevent blockage or oil leakage, which will affect the use effect.
d) For new or long-time hydraulic jacks, because there is more air in the cylinder, the piston rod may have a slight jump phenomenon when it is used. You can reciprocate the hydraulic jacks 2-3 times under no load to eliminate Air in the cavity. For long-term idle jacks, the seals harden due to long-term non-operation of the seals, which affects the service life of the hydraulic jacks. When the hydraulic jacks are not in use, the hydraulic jacks are reciprocated 2-3 times a month without load. .
Six. Precautions for use and maintenance of synchronous hydraulic jacks:
1. The working medium of this pump is YC-N46D hydraulic oil, but it is not allowed to switch to other brands of oil at will.
2. When using for the first time, the motor should rotate clockwise after being filled with oil. If necessary, open the rain cover of the motor to see if it is running in the forward direction. Please jog the motor several times and idle for a few minutes in order to drain the oil circuit. In the air.
3. Keep the liquid level of the fuel tank above the center line of the oil gauge to prevent the pump from sucking up. When refueling, use a 120-mesh strainer to remove impurities from the oil. For regular use, clean the oil filter every two months, clean the fuel tank once every six months, and replace it with new oil.
4. Normal working oil temperature is 20-70 ° C. When the oil temperature is too high, take cooling measures or stop the pump, and use it after the oil is sufficiently cooled; when the oil temperature is too low, it is not allowed to work directly. .
