Hydraulic jacks are divided into two types: general and special. The so-called universal, of course, can be used anywhere and is more common in people's lives, where hydraulic jacks are most commonly used, for car tire repairs It is elusive, and it may happen at any time during the driving process. However, simple and quick hydraulic jacks usually have their own trunks, so tire problems can only be caused by hydraulic jacks. A small height can be used so that the owner can replace the spare tires at any time, convenient and fast at any time.
The special hydraulic jacks are somewhat different. The overall laying of some bridges, including some problems of the bridge itself, the combination of bridge decks and piers, and the convenient operation of the electric pressure test pump is simple and convenient, all require special jacks to slow down. Falling down, eventually forming a fairly good overall placement effect; of course, as more and more industries need to upgrade the overall jack, efforts to develop the actual use of the jack seem quite good in the current industry.
The common hydraulic jacks are used in a uniform way. Check the safety of the hydraulic jacks before use. This will effectively ensure that there will be no problems during use. The subsequent use should strictly follow the use of hydraulic jacks. Some problems caused by operational errors are likely to bring devastating damage to the hydraulic jack, but the later maintenance, as well as the actual operation and maintenance, must be operated by a dedicated person.
Hydraulic Jack Operating Notices
1. During the prestressed tensioning construction, the tensioning jack should be calibrated with the oil gauge.
2. The prestressed tensioning equipment and the prestressed misalignment tool should be used according to the jack model in the instruction manual for the misaligned tool.
3. Before the jack is used, the jack, the oil pump, and the oil pressure gauge must be calibrated by the legal measurement technical institution authorized by the competent department in time as required, and the correction coefficient thereof shall be determined. The watch number and the jack number are installed and used together.
4. Before tensioning, the corresponding value of the oil gauge reading of the graded loading and the tensioning force should be calculated according to the correction coefficient formula.
