Piston type hydraulic cylinder

Piston type  Hydraulic Cylinder is the most important component of  hydraulic system .It can convert hydraulic to mechanical energy and compatible with a variety of transmission to complete all kinds of mechanical motion.

Hydraulic Cylinder has a simple structure ,the output force,stable and reliable performance and easy maintenance,wide range of applications and so on .

Hydraulic cylinder is the hydraulic system in the implementation of the component, its function is to convert hydraulic energy into mechanical energy. Input hydraulic cylinder is fluid flow and pressure, the output is straight line velocity and force. To complete the hydraulic cylinder piston reciprocating motion, the output of the linear displacement is limited. Structure and role according to the number of classification as the second, the typical structure of hydraulic cylinder (-) double acting double rod hydraulic cylinder as shown for the double-acting double rod hydraulic cylinder chart, mainly by the cylinder 4, piston 5, and two rod 1 and other integral parts, piston rod 1, 5 and 9 connected with a cotter pin. 1 set by the guide rod 7 and 9 orientation, and 6 with V-ring seal, screw 2 for the V-ring of the elastic. There are two end caps 3 and out on the open port. When the right cylinder chamber into the oil, the oil back to the left chamber, the piston left; the contrary, the piston shifts to the right. Since both sides of the piston rod the same diameter, so the effective role of the piston ends of the same size. If the left and right ends of the respective pressure and flow entering the same oil, the piston and the thrust generated from equal speed. This hydraulic cylinder used in the same speed and thrust from small occasions, such as cylindrical grinding machine used to drive the table and so on. Installation: cylinder fixed - table reciprocating piston effective stroke range of three times (larger area). Commonly used in small devices. Rod fixed - Table piston reciprocating in the range of twice the effective stroke (piston fixed cylinder is connected with the table, and out of the oil I can do both ends of the piston rod (hollow piston rod of the oil from the inside ). You can also do the two ends of the cylinder (Xu Yong hose connection). impetus came from the cylinder. commonly used in medium and large equipment (such as clay gun cylinder two oil port in the piston rod end). (b ) double acting single rod hydraulic cylinder single rod hydraulic cylinder features: reciprocating motion at different speeds - commonly used in machine tool work fast and slow feed back. both ends of the area is different, the output thrust is not equal. rodless cavity Suction time - Work to exercise (to overcome the large external load). into the oil chamber when the rod - drive rapid return movement of work component (only to overcome the friction of the role). workbench range of motion is equal to twice the effective stroke of the piston rod . Figure shows the single rod hydraulic cylinder chart. cylinder 1 and bottom welded into one. piston guide 2 by supporting ring 4 ring 5 with a Y-type seal, the piston 2 and rod 3 with a threaded connection. 3 by the piston rod guide sets 6,8-oriented, with a 7 V-ring seal. cover 9 and the cylinder block 1 with a threaded connection, the nut 10 to adjust the tightness of V-ring. Bottom end cap and piston rod head Department of earrings are easy to hinge. so the hydraulic cylinder in the reciprocating motion, its axis can swing freely with the work required, commonly used in hydraulic excavators and other construction machinery. (c) - single action hydraulic cylinder piston as shown in Figure said hydraulic cylinder for the plunger, it can only achieve movement in one direction, return by gravity or spring force or other force to push. In order to get a two-way movement, usually in pairs, using the arrangement of response. plunger driven set of 2 by 3 to guide the plunger and the cylinder do not touch, the cylinder wall without finishing. plunger end is under pressure to ensure there is sufficient thrust piston cylinder and the stability of the plunger generally thicker, larger weight horizontal installation, easy to produce unilateral wear, so should the vertical cylinder piston installation. horizontal installation, in order to reduce weight and improve stability, but with a plunger made of seamless steel tubes. This long stroke hydraulic cylinders commonly used in machine tools such as planer, rail grinding, large broaching machine, metallurgical furnace. (4) - telescopic hydraulic cylinder as shown for the telescopic hydraulic cylinder chart, the main component parts are cylinder 5, the piston 4, the sleeve Pistons 3 and so on. cylinder and out of both ends of the oil port A and B. When I entered the oil A, B port back to the oil, the first piston 3 to the right to promote a campaign, as an effective role in the piston area, so movement Large low speed thrust. a line to the right end of the piston, the secondary piston 4 under the pressure of oil continued to move to the right, its effective area of small, fast movement, but the thrust of small. Socket piston 3 is a piston, but also a second piston cylinder, has a dual role. If the B port into the oil, A port back to the oil, then return to finish first and second piston and a piston 3, only to return. telescopic hydraulic cylinder features: the piston rod out of the trip length, contraction of the structure of small size, suitable for tipper vehicles, such as telescopic boom crane. (e) hydraulic cylinder rack to rack as shown in diagram hydraulic cylinder piston. cylinder by the combination of the two parts welded together, processed on the rack piston rod, gear shafts 9 and 10 fused. When the right end into the oil hydraulic cylinder when the piston to the left rack, rack gear 9 is driven clockwise rotation; the contrary, the counterclockwise rotation. both ends of the adjustment screw 2 adjustable rack piston stroke to change the drive shaft 9, the maximum angle. rack cylinder is the most important feature of linear motion is converted to rotary motion, its simple structure, easy to manufacture, commonly used in mechanical hand and feed grinder body, combination machine tool rotary table, rotary and automatic line clamp body translocation. (based on the work required to design a single rack or two-rack structure)
