Uganda hydraulic cylinder,push bench hydraulic cylinder manufacturer,push bench hydraulic cylinder(Uganda push bench hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory)
push bench hydraulic cylinder are widely used in Uganda,because of long service life,smooth movement,high work efficiency.So our company has designed push bench hydraulic cylinder for customers from Uganda.
When the push bench hydraulic cylinder is installed, the piston and the push bench hydraulic cylinder head and other parts have large mass, large size and large inertia, even if there is a lifting equipment auxiliary installation, because the specified clearance is small, no matter how hard it will be put into, therefore, the end of the piston or the push bench hydraulic cylinder head boss is easy to cause scars when it hits the inner surface of the push bench hydraulic cylinder wall. The solution to this problem: for a large number of small products, the use of autocratic assembly oriented tools during installation; For heavy, thick and large large and medium-sized push bench hydraulic cylinders, only careful and careful operation can be avoided.
Factors that should be considered when selecting the oil seal in the push bench hydraulic cylinder: some specific factors should be taken into account when selecting the oil seal in the push bench hydraulic cylinder, so as to have correct consideration and get accurate results, and then avoid wrong selection. The factors and aspects that should be taken into account are eight: push bench hydraulic cylinder diameter, piston rod diameter, piston rod and piston groove size, push bench hydraulic cylinder working pressure, push bench hydraulic cylinder movement speed, hydraulic system oil temperature and push bench hydraulic cylinder working environment.
The "O" ring can be used as an auxiliary seal inside the push bench hydraulic cylinder, and the elastic force of the "O" ring makes the sealing slip ring close to the sealing surface, generating sealing pressure to achieve sealing. When the internal hydraulic pressure increases, the "O" ring will further deform and squeeze the slip ring, thereby increasing the sealing pressure and improving the sealing performance. The structure has the characteristics of low friction coefficient, good wear resistance, automatic compensation for wear and absorption of hard particles in the push bench hydraulic cylinder, and can be completely sealed.
push bench hydraulic cylinder use should try to avoid sealing belt into the push bench hydraulic cylinder. As a simple sealing material, polytetrafluoroethylene plastic sealing tape is often used in installation and inspection, and if the winding method of the linear and ribbon-shaped sealing material is wrong, the sealing tape will be cut off and enter the push bench hydraulic cylinder. The wire belt seal will not have any effect on the winding of the sliding part, but it will cause the check valve of the push bench hydraulic cylinder to fail to operate or the buffer regulating valve can not be adjusted to the end. For the circuit, it may cause the action of the reversing valve, the relief valve and the reducing valve to fail.
Classification and application of cylinders.
Hydraulic cylinder is divided into single acting hydraulic cylinder, double acting cylinder, combined hydraulic cylinder, swing hydraulic cylinder. Single acting cylinder is divided into plunger type hydraulic cylinder, single piston rod hydraulic cylinder, double piston rod hydraulic cylinder, telescopic hydraulic cylinder. Plunger type hydraulic cylinder: the plunger moves only in one direction, and the return stroke is to push the plunger back using its own weight or load. Single piston rod hydraulic cylinder: The piston moves only in one direction, and the return stroke is to push the plunger back using dead weight or load. Double piston rod hydraulic cylinder: both sides of the piston are equipped with piston rods, and pressure oil can only be supplied to one side of the piston. The return stroke usually uses spring force, gravity or external force. Telescopic hydraulic cylinder: It obtains long stroke with short cylinder. The hydraulic oil is pushed out from large to small section by section, and the external force is reduced from small to large.
What factors does the movement speed of the cylinder in the hydraulic system depend on?
The hydraulic system should be the piston movement in the cylinder, and the speed should also be the speed of the piston, according to the piston speed formula: v=4qm/pai*(D^2-d^2) where q is the flow rate of the input hydraulic cylinder, m is the volumetric efficiency of the hydraulic cylinder, D, d is the diameter of the piston and piston rod, because other factors are determined, the movement speed of the cylinder depends on the flow rate.
