Nigeria metallurgical cylinder

(Nigeria metallurgical cylinder,produced by Hengyu Group)

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

Introduction to metallurgical cylinder:

Most of the failure of the metallurgical cylinder is because there is a foreign body in the metallurgical cylinder into the failure of the metallurgical cylinder, the most problematic is that it is difficult to determine when the foreign body is into the metallurgical cylinder. After a foreign body enters, if the outer side of the sliding surface of the piston is equipped with a seal with a lip edge, then the lip edge of the seal can scrape the foreign body when working, which is beneficial to avoid scratching. However, the piston equipped with 0-shaped sealing ring has a sliding surface at both ends, and foreign bodies are sandwiched between this sliding surface, which is easy to form scars.

Do not regularly check the damage of the chrome layer of the metallurgical cylinder: completely extend the metallurgical cylinder and carefully check whether there is any surface damage such as injury, strain, welding slag, such as the surface damage position, in the metallurgical cylinder block < 20cm, and the damage depth < 5mm, should be repaired in time to prevent long-term damage to the metallurgical cylinder seal. Welding slag is strictly prohibited on the surface of the metallurgical cylinder.

The metallurgical cylinder is mainly composed of body, piston, piston rod, metallurgical cylinder head, metallurgical cylinder bottom, piston rod head and related auxiliary devices. The piston divides the metallurgical cylinder into two chambers, and moves reciprocally in the metallurgical 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 metallurgical cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the metallurgical 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 metallurgical 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 metallurgical cylinder bottom and the metallurgical cylinder head is serious, so the buffer deceleration should be set at both ends of the metallurgical cylinder The working medium of the metallurgical cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; metallurgical 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 metallurgical cylinder: The buffer structure of the metallurgical cylinder is to prevent the piston from colliding with the metallurgical cylinder head at the end of the stroke.

When the metallurgical cylinder needs to be stored for a period of time, please follow the recommended methods: The metallurgical cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the metallurgical 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 metallurgical cylinder should not be in direct contact with water vapor for a long time. The metallurgical cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the metallurgical 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 metallurgical cylinder Before working, the metallurgical cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the metallurgical cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

Answers to some questions about metallurgical cylinder:

Why manual forklift oil cylinder can not lift up?
Manual hydraulic forklift truck often can not be pressed up, there are several reasons: for manual hydraulic truck: 1) There is no hydraulic oil 2) the purity of the oil is not enough 3) the adjusting bolt is too close or the adjusting screw is too tight, so that the valve is always open, 4) there is an air in the hydraulic cylinder. Method: 1) Refueling 2) Oil change 3) air discharge. For manual hydraulic stacker, also called manual lift car 1) Less than the amount of oil 2) impurities in the hydraulic oil, so that the check valve can not be closed. Method 1) Add enough hydraulic oil 2) Remove the cylinder, screw off the bottom plate, remove the impurities in the bottom plate.

How to distinguish the size of hydraulic cylinder cavity?
The hydraulic cylinder has a rod cavity and a rodless cavity. The rod cavity is the cavity that the piston rod extends out. The rod cavity is of course small due to the existence of the piston rod. That's just relative.
