Heavy pull rod hydraulic cylinder adopts pull rod structure, 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.
Heavy rod hydraulic cylinder installation and connection methods are diverse, including flange, single ear, double ear, foot seat, hinge shaft, and can add connection accessories on the piston rod, such as Y joint, I joint, joint bearings, etc. This series of pull rod hydraulic cylinder can be made of double rod cylinder that is HOD series, and can be customized, 1) high temperature conditions, using high temperature seals, 2) high pressure keeping requirements, using zero leakage seals, 3) can add buffer function, 4) oil port can be changed G thread, 5) piston rod can be enlarged according to demand, 6) plus stroke switch, 7) Can be made magnetic induction cylinder (cylinder with stainless steel, piston with copper material, plus magnetic induction switch).
The force of the heavy tie rod hydraulic cylinder is determined by the cylinder diameter and the use pressure, the use pressure is less than or equal to 14Mpa, and the following is the thrust of each different cylinder diameter under the full load of 14Mpa. If the force is pulled, it is less than the thrust.
The heavy pull rod hydraulic cylinder is composed of a press plate, front cylinder head, back 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. The front and back covers are made of No. 45 cylinder material, the piston rod is No. 45 chrome plated layer thickness 2-3 wires, the cylinder barrel is No. 20 rolled tube, and the tie rod material is A3 (the large cylinder diameter is tempered with No. 45). The seal adopts the brand of Taiwan DZ.
Based on the size of the ordinary drawbar cylinder, the cylinder material is changed to stainless steel, the magnetic ring is added to the copper piston, and the magnetic induction switch is added to the cylinder to realize the automatic detection of the cylinder stroke in cooperation with the electrical system. Various installation methods can be processed into magnetic induction cylinders.
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 =14Mpa*21=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.
