Light rod hydraulic cylinder is a low-cost cylinder of the same specification, because the pressure is small, the composition of the cylinder cylinder thickness is thin, the piston rod is relatively small, the front and back covers are cast, and the low pressure seals are relatively low. The light pull rod hydraulic cylinder adopts the pull rod structure, and the cylinder and the front and back covers are connected together by 4 screw rods, and then tightened with lock nuts. Easy maintenance, just loosen the lock nut, you can take out the front cover, replace the seal or other accessories.
The lightweight tie rod hydraulic cylinder is installed and connected in a variety of ways, including flange, single ear, double ear, foot seat, hinge shaft, and can add connection accessories on the piston rod, such as fisheye joints, type I joints, etc. This series of pull rod hydraulic cylinder can be made of double rod cylinder, and can be customized, 1) high temperature conditions, using high temperature seals, 2) plus stroke switch, 3) can be made of magnetic induction cylinder (cylinder with stainless steel, piston with copper material, plus magnetic induction switch), 4) can be added buffer function
1) Use instead of cylinder. The original system used pneumatic, but due to various reasons (such as hydraulic control, the pursuit of more stable action, such as the strength of the pneumatic is not enough)
2) The system pressure is very small, considering the economy, using standard oil cylinder.
The force of the light tie rod hydraulic cylinder is determined by the cylinder diameter and the use pressure, the use pressure is less than or equal to 7Mpa, and the following is the thrust of each different cylinder diameter under the full load of 7Mpa. If the force is pulled, it is less than the thrust.
The light tie rod hydraulic cylinder is composed of front cylinder head, rear cylinder head, piston, cylinder, piston rod, 4 screw rods, 8 locking nuts and gaskets, 1 piston locking nut and gasket, 1 piston rod end matching locking nut, a full set of seals, rod end protective sleeve, oil port plug. Because the cylinder of this series is only 7Mpa, the front and back covers are made of castings HT200, the piston rod is No. 45 chrome plated layer thickness 2-3 wires, the cylinder barrel is No. 20 rolled tube, and the rod material is A3. The seal adopts the brand of Taiwan DZ.
The oil test is carried out on the test bench. The implementation steps are as follows: the oil pipe of the test bench is connected to the oil inlet and outlet of the oil cylinder, the pressure is put on the test bench, the oil of the test bench enters the oil cylinder, and the oil cylinder is reversed through the solenoid valve, so that the oil cylinder can go back and forth several times, and the gap between the rod end of the cylinder, the cylinder cylinder and the front and back cover is observed whether there is oil leakage. Test pressure =7Mpa*1.5=10.5Mpa. Check whether the oil cylinder has been tested, very simple, after receiving the cylinder, remove the plug of the oil port, see whether there is oil trace, there is oil trace indicates that the oil test has been done.
Provide sample data, CAD\ 3D gallery, designers can refer to the size to see whether it is suitable for machine space requirements. The size of the real object is consistent with the sample data. Adopt strict incoming inspection, factory testing, reliable and stable quality. Can be customized non-standard, such as large quantity can be specially customized mold, such as a small amount of turning processing.
