Burma hydraulic cylinder,vehicle hydraulic cylinder manufacturer,vehicle hydraulic cylinder(Burma vehicle hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)
vehicle hydraulic cylinder are widely used in Burma,because of smooth movement,high work efficiency,excellent fatigue and impact resistance.So our company has designed vehicle hydraulic cylinder for customers from Burma.
The vehicle hydraulic cylinder is mainly composed of body, piston, piston rod, vehicle hydraulic cylinder head, vehicle hydraulic cylinder bottom, piston rod head and related auxiliary devices. The piston divides the vehicle hydraulic cylinder into two chambers, and moves reciprocally in the vehicle hydraulic 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 vehicle hydraulic cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the vehicle hydraulic 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 vehicle hydraulic 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 vehicle hydraulic cylinder bottom and the vehicle hydraulic cylinder head is serious, so the buffer deceleration should be set at both ends of the vehicle hydraulic cylinder The working medium of the vehicle hydraulic cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; vehicle hydraulic 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 vehicle hydraulic cylinder: The buffer structure of the vehicle hydraulic cylinder is to prevent the piston from colliding with the vehicle hydraulic cylinder head at the end of the stroke.
The internal leakage of the vehicle hydraulic cylinder should be prevented when the vehicle hydraulic cylinder is used. The internal leakage of vehicle hydraulic cylinder includes the leakage caused by excessive wear of vehicle hydraulic cylinder block seal, piston rod and seal cover seal and piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time.
When the control pressure of the hydraulic system is too low, the vehicle hydraulic cylinder will appear wrong or no action, because the throttle resistance in the control pipeline may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is interfered with. At this time, check the control pressure source to ensure that the pressure is adjusted to the specified value of the system.
At the rated pressure, the thrust of the vehicle hydraulic cylinder is determined by what factors: at the rated pressure of the oil pump, the work done by the vehicle hydraulic cylinder is related to the diameter of the vehicle hydraulic cylinder, but not to the stroke of the vehicle hydraulic cylinder. Moreover, the larger the vehicle hydraulic cylinder diameter, the larger the area, and the greater the pressure obtained. To this point, we should have a correct understanding and clear understanding, so as to avoid problems in the use of the vehicle hydraulic cylinder.
How to set the stroke of the cylinder?
Self-design should be based on product demand and practical application. The stroke of standard cylinder depends on the parameters the customer requires. The hydraulic cylinder is a linear motion actuator whose output force is proportional to the effective area of the piston and the pressure difference on both sides. Its function is to convert hydraulic energy into mechanical energy. The input of the hydraulic cylinder is the flow rate and pressure of the fluid, and the output is the speed and force of the linear motion. The piston of the hydraulic cylinder can complete the linear reciprocating movement, and the linear displacement of the output is limited. Hydraulic cylinder is an energy conversion device that converts hydraulic energy into mechanical energy of reciprocating linear motion. The hydraulic cylinder is basically composed of cylinder body, cylinder head, piston and piston rod, sealing device, buffer device and exhaust device.
How to calculate the tonnage of hydraulic cylinder? The tonnage of the cylinder refers to the output force of the cylinder under rated working pressure: 1, for single rod piston hydraulic cylinder, it can be calculated by the area of the circle corresponding to the inner diameter of the cylinder A (square centimeter), and the rated working pressure of the system p (mpa), the value is equal to 10pA kg force, and the ton is 0.01pA. 2, for the double rod piston hydraulic cylinder, with A(square centimeter) to indicate the cylinder cylinder diameter and piston rod outer diameter defined by the ring area, with p (mpa) to indicate the rated working pressure of the system, the output force of the cylinder is 0.01pA ton force.
