Since the emergence of large-tonnage hydraulic jacks, it has brought great convenience to our work and has been widely used in various places. How to extend its service life? The editor will give you a brief introduction to the relevant knowledge points below.
1. Improve the design of large-tonnage hydraulic jacks: After many demonstrations, the high-quality priority valve and load-sensing full hydraulic steering gear are adopted. The new system can prioritize flow distribution to it according to steering requirements, regardless of load size or steering wheel speed. Both can ensure sufficient oil supply, and the remaining part can be used by the working device circuit, thereby eliminating the power loss caused by the excessive oil supply of the steering circuit, improving the system efficiency, and reducing the working pressure of the large tonnage hydraulic jack;
2. Optimize the design of the boom cylinder and hydraulic pump shape of the large tonnage hydraulic jack to reduce the working pressure of the system. Meet the lifting force and speed requirements of the boom cylinder;
3. In the process of using large-tonnage hydraulic jacks, attention should also be paid to the correct use and maintenance of the hydraulic oil pump of the loader. The hydraulic oil is regularly added or replaced to maintain the cleanliness of the hydraulic oil and strengthen daily inspection and maintenance.

Things to consider when buying large-tonnage hydraulic jacks: the quality of large-tonnage hydraulic jacks. The quality of large-tonnage hydraulic jacks is good or bad. Choose qualified products from regular manufacturers. The quality is guaranteed and durable. The price of large tonnage hydraulic jacks. The price of large-tonnage hydraulic jacks is high or low, so you should choose large-tonnage hydraulic jacks reasonably according to your own budget.
The reason why the base of the large-tonnage hydraulic jack should be firm: all the forces are except for the piston cylinder of the large-tonnage hydraulic jack to lift, but the base is receiving all the forces, so the base needs to be firmly placed; if the base of the machine is not stable It will cause it to tilt during construction; note that there is an oil valve on the base, so its stability is also related to the influence of the oil valve; pay attention to the position of the base of the large tonnage hydraulic jack to be flat, if it is not flat, it should be flat Sheet pad.
