(Panama tension cylinder,produced by Hengyu Group）

tension cylinder are widely used in Panama，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed tension cylinder for customers from Panama.

Introduction to tension cylinder:

Under normal circumstances, the tension cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the tension cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the tension cylinder and the end cover, the piston and the piston rod, the piston and the tension cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the tension cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.

When the tension cylinder needs to be stored for a period of time, please follow the recommended methods: The tension cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the tension cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil tension cylinder should not be in direct contact with water vapor for a long time. The tension cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the tension cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the tension cylinder Before working, the tension cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the tension cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

When the tension cylinder is installed, the piston and the tension 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 tension cylinder head boss is easy to cause scars when it hits the inner surface of the tension 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 tension cylinders, only careful and careful operation can be avoided.

tension cylinder hydraulic oil selection: The recommended working oil viscosity of the tension cylinder is 10 ~ 110cSt (1.8 ~ 15E), ISO VG46 hydraulic oil. The normal working oil temperature is 10 ~ 70℃, and the ambient temperature is in the range of -20 ~ 80℃. When the ambient temperature and service temperature are low, the hydraulic oil with lower viscosity can be selected.

Answers to some questions about tension cylinder:

Injection molding machine die thimble on the side of the feed nozzle, the oil cylinder pull the thimble shift, how to debug the oil cylinder?
The cylinder is connected with the neutron of the injection molding machine, the neutron is retreated after the opening mold is in place, the cylinder taps the thimble plate to the top, and then takes, and the neutron is reset.

What is the meaning of dead volume in hydraulic cylinder?
Closed volume, also known as dead zone volume Positive displacement pump is dependent on the change of sealing working volume to achieve suction and pressure oil, in order not to make the suction and pressure oil cavity interworking, there is an oil sealing area between the suction and pressure oil cavity, when the sealing working volume passes through the oil sealing area, neither pressure oil cavity nor oil suction cavity communication, forming a closed sealing volume. The unloading groove is opened, and the grooving principle is that the sealing volume decreases and the oil pressure chamber is communicated, and the sealing volume increases and the oil suction chamber is communicated.
