1, single-acting hydraulic jacks single-acting hydraulic jack can also be called a one-way hydraulic jacks, jack of separate hydraulic jacks, it needs a way to cooperate with an electric pump, hollow jack, usually a small stroke and small tonnage hydraulic jacks. Single-acting hydraulic jack main feature is the small body length, compact, more suitable for use in a small place; 2, double-acting hydraulic jack double-acting hydraulic jack also be referred to as a double-acting hydraulic jacks, it is also a separate hydraulic jack jack jack factory direct, single-acting hydraulic jack is different is that it relies on double-acting hydraulic pump station to provide power, under normal circumstances, jacks, double-acting hydraulic jack for the big trip, large-tonnage hydraulic jacks, double acting hydraulic jack load tonnage of substantially between 100T-1000T. Hydraulic jacks according to work is divided into two categories mainly on jack, each of which have unique properties, applications are not think the same, we can select the appropriate hydraulic jacks during use according to different needs. Hydraulic fluid power components needed in the main power components, actuators, control components and auxiliary components. Hydraulics components which are generating power for the hydraulic system components, large-tonnage hydraulic jacks, including a variety of hydraulic pumps. Pumps rely on the principle of a change in the volume of work, it is generally referred to as the volume of the hydraulic pump. The gear pump is the most common form of hydraulic pump, it is engaged by rotation of the two gears so that the liquid motion. There are other hydraulic vane pumps, piston pumps, hydraulic pump when selecting the main issues that need attention include energy consumption, efficiency, and reduce noise.
