Turkey hydraulic cylinder,rack cylinder manufacturer,rack cylinder
(Turkey rack cylinder,produced by Hengyu Hydraulic Cylinder Factory）
rack cylinder are widely used in Turkey，because of no need for deceleration device，long service life，smooth movement.So our company has designed rack cylinder for customers from Turkey.
When the rack cylinder is in use, ensure that the rack cylinder and the surrounding environment should be clean. The tank should be sealed to prevent contamination. Pipelines and fuel tanks should be cleaned to prevent falling off the oxide sheet and other debris. Clean with lint-free cloth or special paper. Twine and binder should not be used as sealing materials. Hydraulic oil according to the design requirements, pay attention to the change of oil temperature and oil pressure. When there is no load, unscrew the exhaust bolt for exhaust.
When the rack cylinder is installed, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the rack cylinder head, earring (or middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent rigid interference and cause unnecessary damage.
The rack cylinder is mainly composed of body, piston, piston rod, rack cylinder head, rack cylinder bottom, piston rod head and related auxiliary devices. The piston divides the rack cylinder into two chambers, and moves reciprocally in the rack cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the rack cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the rack cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the rack cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the rack cylinder bottom and the rack cylinder head is serious, so the buffer deceleration should be set at both ends of the rack cylinder The working medium of the rack cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; rack cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the rack cylinder: The buffer structure of the rack cylinder is to prevent the piston from colliding with the rack cylinder head at the end of the stroke.
The main role of the rack cylinder: the rack cylinder is an executive element in the hydraulic transmission system, which is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic motor realizes continuous rotary motion, while the rack cylinder realizes reciprocating motion. The structure of the rack cylinder has three categories: piston rack cylinder, plunger rack cylinder, swing rack cylinder, piston rack cylinder and plunger rack cylinder to achieve reciprocating linear motion, output speed and thrust, swing rack cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the rack cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The rack cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.
How does the hydraulic solenoid valve realize that the cylinder stops at any position?
Use an O-type medium function solenoid directional valve, or use a Y-type solenoid directional valve and a hydraulically controlled check valve.
How many tons can a 10mpa cylinder with a diameter of 100 hold up?
About 8 tons. Algorithm: Cylinder cross-sectional area = π* (100/2) ^2=3.14*2500=7850 square mm = 0.00785 square meters pressure = pressure * Cross-sectional area = 10000000Pa*0.00785 square meters = 78500 n mass = pressure /g = 78500 N ÷9.8 n/kg = 8010 kg = 8.01 Tons.
