Holland hydraulic cylinder,tailplate hydraulic cylinder manufacturer,tailplate hydraulic cylinder(Holland tailplate hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)
tailplate hydraulic cylinder are widely used in Holland,because of no need for deceleration device,long service life,smooth movement.So our company has designed tailplate hydraulic cylinder for customers from Holland.
The tailplate hydraulic cylinder is mainly composed of body, piston, piston rod, tailplate hydraulic cylinder head, tailplate hydraulic cylinder bottom, piston rod head and related auxiliary devices. The piston divides the tailplate hydraulic cylinder into two chambers, and moves reciprocally in the tailplate 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 tailplate hydraulic cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the tailplate 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 tailplate 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 tailplate hydraulic cylinder bottom and the tailplate hydraulic cylinder head is serious, so the buffer deceleration should be set at both ends of the tailplate hydraulic cylinder The working medium of the tailplate hydraulic cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; tailplate 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 tailplate hydraulic cylinder: The buffer structure of the tailplate hydraulic cylinder is to prevent the piston from colliding with the tailplate hydraulic cylinder head at the end of the stroke.
tailplate hydraulic cylinder body inspection: The inner surface of the tailplate hydraulic cylinder and the piston seal are the main factors causing the leakage in the tailplate hydraulic cylinder, if the tailplate hydraulic cylinder has a longitudinal tensile mark, even if the new piston seal is replaced, it can not effectively eliminate the fault, the inner surface of the tailplate hydraulic cylinder mainly checks whether the dimensional tolerance and shape and position tolerance meet the technical requirements, there is no longitudinal tensile mark, and measures the depth of the longitudinal tensile mark, in order to take the corresponding solution.
Do not enter foreign bodies when installing the tailplate hydraulic cylinder block. The place where the installation operation is carried out, the conditions are not good, and foreign bodies can be entered unconsciously. Therefore, the installation site must be cleaned up around, especially the place where the parts are placed must be cleaned, so that there is no dirt.
tailplate hydraulic cylinder diameter, rod diameter, stroke determination: Choose national standards or other standards tailplate hydraulic cylinder, avoid the selection of non-standard size, otherwise the difficulty of processing and manufacturing costs will be increased. The length of the tailplate hydraulic cylinder guide is determined by the length of the stroke. Check the strength of tailplate hydraulic cylinder, piston rod, screw, etc. according to the working pressure or load. At the same time, working pressure, ambient temperature, working medium and running speed are also the key to selecting seals.
What is a variable amplitude cylinder?
The type of variable amplitude cylinder is: double acting piston type cylinder, single acting plunger type cylinder, double acting two-stage telescopic cylinder. Double acting piston cylinder is the most common application. The oil cylinder has two oil outlets, and when the oil is fed into the A port, the oil is returned to the B port; If the oil inlet of the B port is returned to the oil of the A port, the reciprocating movement of the piston depends on the effect of pressure. Single-acting plunger (or piston) cylinder has only one oil port, the pressure oil can only supply oil to one side of the plunger in the cylinder, the plunger moves in one direction under the action of pressure oil, and the return stroke of the plunger is driven by the gravity of the lifting arm, such as the LT1040 truck crane variable amplitude cylinder. The double-acting two-stage telescopic cylinder is a set structure, and the two-stage piston rod is like a tie rod antenna set in the cylinder barrel.
What is the difference between gas-hydraulic pressurized cylinder, pneumatic cylinder and oil cylinder?
The cylinder block is small and the force is large, constant speed and variable speed can be used (easy to change), the adjustment of the output is also convenient, and the freedom of transmission is high. However, maintenance costs and installation costs are high, and there is the trouble of mild oil pollution. Easy cylinder control, low price, easy access to energy. But the force is small, and can not achieve the effect of stable speed. The gas-liquid pressurized cylinder has the advantages of both of the above: environmental protection and energy saving, easy control, and simple adjustment. However, the output of the trip has certain restrictions, more suitable for short trips, large output, but also environmental protection and energy saving and low configuration of the occasion.
