Selection of hydraulic jack
source:Industry News release time:2022-09-16 Article author:yu Popular:Air band saw
The choice of power
What is the tonnage of the jack required for work? After considering the impedance loss of the seal and the support impedance loss between the jack and the piston, its force is 94%-95% of the rated value. When the jack needs to run continuously, the recommended jack The tonnage is higher, usually calculated at 70%-80% of the rated value.
The choice of itinerary
If there is enough space, choose a jack with a longer stroke than is actually required to increase the scalability, reliability and durability of the system.
3. The choice of type
Jacks are basically divided into two categories: single acting (spring return or load return) and double acting, CLL and DS type jacks have no spring return function and can only be retracted by load or gravity.
Fourth, the choice of quantity
Whether multiple jacks are required to operate simultaneously.
5. Warnings and precautions during installation and operation
1. Make sure that the load acts on the center of the jack and its direction is along the direction of the jack;
2. The allowable eccentric load must be within the technical requirements of the jack;
3. Install the jack by installing the flange on the neck thread;
4. When connecting the quick connector, it must be connected, screwed tightly, and the two ends fit together;
5. Avoid excessive extension of the jack piston;
6. It is strictly forbidden to disconnect the oil pump interface when the jack is under load;
7. Please keep away from heat, fire, rain, sea water, humidity, etc.;
8. If there is any oil leakage / oil seepage, check it immediately;
9. When the pipe joint of the tension end is completely blocked, it is forbidden to operate the double-acting jack. If the jack equipped with the self-sealing pipe joint suddenly stops running, the greatest possibility is
It is because the pipe joint is loose that the oil circuit is blocked.
6. Non-standard jacks and special jacks
Non-standard jacks can be customized according to your requirements, or jacks above 1000 tons
1. How much tonnage force is needed
2. Required stroke and body height
3. Are all piston, neck or base threads required
4. Required frequency and conditions of use
