Product name: Electro-hydraulic jack
Product introduction: Electric jack set is also called electric hydraulic jack. It is a combination of hydraulic cylinder and electric pump station, which can realize various forms of operation such as jacking, pushing, pulling and squeezing. Also called electro-hydraulic jack.
Electro-hydraulic jack product details
1. Definition of electro-hydraulic jack: Also known as electro-hydraulic jack, it is a combination of a hydraulic cylinder and an electric pump station, which can realize various forms of operations such as jacking, pushing, pulling, and squeezing.
Second, the electric hydraulic jack model: QF, YZF, DY.
Third, the electric hydraulic jack tonnage: 50 tons, 100 tons, 200 tons, 320 tons, 500 tons, 630 tons, 800 tons, 1,000 tons.
4. Travel of electro-hydraulic jack: 125mm, 160mm, 200mm.
V. Brands of electro-hydraulic jacks: Hailifeng, Texas, Enpac, USA, IHP, EMMET, USA, Bunker, Able, USA, Simplex, USA, EAGLE-PRO, Germany, SAIVS, Germany, EM, Yale, Germany, Villeco, Germany, YATO in Europe, Rennes in France, MASADA in Japan, OJ in Japan, BMB in Taiwan, Shanghai HSBC.
6. Working principle of electro-hydraulic jack: The most basic principle on which hydraulic transmission is based is the Pascal principle, that is, the pressure across the liquid is the same. In this way, in a balanced system, the pressure applied on the smaller piston is compared. Smaller and larger pistons exert more pressure, which keeps the liquid still. Therefore, through the transfer of liquid, different pressures on different ends can be obtained, so that the purpose of a transformation can be achieved. The hydraulic and electric jacks we commonly use are based on this principle to achieve force transmission.
VII. Application range of electric hydraulic jacks: Electric jacks are widely used in electric power maintenance, bridge repairs, jacking of heavy objects, static pressure piles, foundation settlement, bridge and ship construction, especially in highway and railway construction and mechanical adjustment and equipment disassembly. etc.
Eight, the use of electric hydraulic jack:
1. Before use, you must check whether each part is normal.
2. Strictly abide by the provisions in the main parameters when using, and avoid over-high overload, otherwise, when the lifting height or lifting tonnage exceeds the regulations, serious oil leakage will occur on the top of the electro-hydraulic jack.
3. Please refer to the electric pump instruction manual for electric pump.
4. The center of gravity of the heavy object should be selected appropriately. The focus point of the electro-hydraulic jack should be reasonably selected. The bottom surface should be flat. At the same time, the soft and hard conditions of the ground should be considered. The tough wood should be lined and placed stably to prevent the load from sinking or tilting.
5. After the electro-hydraulic jack lifts the heavy object, it should be supported firmly with a support in time. It is forbidden to use the ultra-high-pressure large-tonnage electric jack as a support. If you need to support heavy objects for a long time, please choose self-locking jack
6. If several electro-hydraulic jacks are required to be lifted at the same time, please use type synchronous jacks. In addition to properly enlarging tonnage electric jacks, multi-top diverter valves should be used, and the load of each large-ton electric jack should be balanced. Lift speed synchronization. It is also necessary to consider the situation where the ground may sink due to uneven weight to prevent the tilt of the weighted object from causing danger.
7. 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. To lower the piston rod, loosen the handwheel of the manual oil pump slightly in the counterclockwise direction, unload the cylinder, and the piston rod will gradually descend. Otherwise, the descending speed will be dangerous.
8. The hydraulic jack of this electric motor is retracted. After lifting, it can be quickly taken out, but the connected hose cannot be used to pull the ultra-high pressure large tonnage electric jack.
9. Do not exceed the rated stroke when using by the user, so as not to damage the electric hydraulic jack.
10. Avoid severe vibration of the jack during use.
11. It is not suitable for use in the workplace with acid and alkali and corrosive gas.
12, the user should regularly check and maintain according to the use situation.
