High -precision hydraulic cylinder

High -precision hydraulic cylindersThey are key components in a wide range of industrial equipment that require a reliable and accurate linear movement. The choice of a suitable cylinder, its proper operation and timely maintenance are critical to ensure the maximum performance and durability of the system. In this article we will consider the main aspects associated withhigh -precision hydraulic cylinders, including their types, selection criteria, application and maintenance features.

What is a high -precision hydraulic cylinder?

High -precision hydraulic cylinder- This is a device that converts the hydraulic energy of the liquid into the mechanical energy of linear motion with increased accuracy and minimal tolerances. They differ from standard cylinders with more stringent requirements for materials, processing and assembly, which ensures a more smooth and accurate movement of the piston.

Types of high -precision hydraulic cylinders

There are several main typeshigh -precision hydraulic cylinders, each of which is intended for certain applications:

• Unilateral cylinders: perform work only in one direction, the return is carried out by a spring or under the influence of external power.
• Bilateral cylinders: perform work in both directions, providing controlled movement both during extending and when drawing in the rod.
• Telescopic cylinders: consist of several sections that allow you to reach a long stroke with compact sizes in a folded state.
• Synchronous cylinders: used to simultaneously move several objects with high accuracy.

Criteria for choosing a high -precision hydraulic cylinder

When choosinghigh -precision hydraulic cylinderThe following factors must be taken into account:

• The required accuracy of movement: determines the permissible deviations and backlash.
• Working pressure and effort: must correspond to the loads that occur in the system.
• The diameter of the cylinder and the stroke of the rod: determine the dimensions and capabilities of the cylinder.
• Type of working fluid: affects the choice of seals and materials.
• Operating conditions: take into account the temperature, humidity, the presence of aggressive media, etc.

The use of high -precision hydraulic cylinders

High -precision hydraulic cylindersWidely used in various industries, where high accuracy and reliability is required:

• Metal processing machines: to control the movement of the tool and workpieces.
• Pressual equipment: to create accurate effort during stamping and molding.
• Robotics: for accurate positioning of manipulators.
• Aviation industry: for controlling the elements of the chassis and wing mechanization.
• Medical equipment: for accurate movement of components in diagnostic and surgical devices.
• Construction equipment: for example, the company LLC Internal Mongolia Zhitsyan Construction equipment (https://nmgrq.ru/) offersHigh -precision hydraulic cylindersFor excavators and other special equipment, ensuring reliable and durable operation of the equipment.

Maintenance and repair of high -precision hydraulic cylinders

Regular maintenance and timely repairhigh -precision hydraulic cylindersIt is necessary to ensure their reliable and durable work. The main services for maintenance include:

• Regular verification for leaks and damage.
• Replacement of seals and worn parts.
• Flushing and replacing the working fluid.
• Oil level control in the hydraulic system.
• Lubrication of the rod and other mobile parts.

Example: selection of a cylinder for the press

Let's say you need to chooseHigh -precision hydraulic cylinderFor a press designed for stamping parts made of sheet metal. The press must provide a force of 100 tons with an accuracy of 0.1 mm. The working pressure in the hydraulic system is 320 bar. In this case, you will need a bilateral cylinder with a piston diameter of about 200 mm and a stem, corresponding to the required stamping height. It is important to pay attention to the quality of the seals and material of the rod in order to ensure high wear resistance and durability of the cylinder.
