Czech Republic bending machine hydraulic cylinder

(Czech Republic bending machine hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory)

bending machine hydraulic cylinder are widely used in Czech Republic,because of excellent fatigue and impact resistance,no need for deceleration device,long service life.So our company has designed bending machine hydraulic cylinder for customers from Czech Republic.

Introduction to bending machine hydraulic cylinder:

bending machine hydraulic cylinder diameter, rod diameter, stroke determination: Choose national standards or other standards bending machine hydraulic cylinder, avoid the selection of non-standard size, otherwise the difficulty of processing and manufacturing costs will be increased. The length of the bending machine hydraulic cylinder guide is determined by the length of the stroke. Check the strength of bending machine hydraulic cylinder, piston rod, screw, etc. according to the working pressure or load. At the same time, working pressure, ambient temperature, working medium and running speed are also the key to selecting seals.

When the bending machine hydraulic cylinder thrust is insufficient, check the hydraulic circuit for leaks. Including leakage of valves and hydraulic lines. The inspection method is to check and eliminate the leakage of the hydraulic connection line by manipulating the reversing valve. Also consider the relief valve. If the relief valve enters the dirt and jams the spool, so that the relief valve is normally open, the hydraulic oil will flow directly back to the tank through the relief valve bypass, resulting in no oil in the bending machine hydraulic cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the bending machine hydraulic cylinder still cannot get the thrust required for continuous action without action. If the regulating pressure is low, the pressure is insufficient to achieve the required vertebra force, which is manifested as insufficient thrust. Check and adjust the relief valve at this time.

When the bending machine hydraulic cylinder wear is serious, you can try to use an alloy scraper to shave grooves with a depth of more than 1mm on the surface of the slip injury, then clean the grooves with acetone, apply the adjusted TS311 anti-wear repair agent on the polished surface with the bending machine hydraulic cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the bending machine hydraulic cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the bending machine hydraulic cylinder can meet the requirements by grinding. However, the life and reliability of this repair bending machine hydraulic cylinder are not high.

If air enters the hydraulic system, the bending machine hydraulic cylinder will not operate normally, mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced.

Answers to some questions about bending machine hydraulic cylinder:

How is the hydraulic cylinder tempered?
The purpose of the tempering treatment is to make the piston rod have comprehensive mechanical properties of strength, hardness, plasticity and toughness, and the internal structure is uniform and fine tempered sorbite, so as to prepare the organization for subsequent surface quenching. The length of the long cylinder piston rod is 3800-4200, and the diameter is Φ90-Φ110mm, so its heating equipment uses a 150KW well resistance furnace or 600KW suspension continuous resistance heating furnace, and the temperature is controlled by two areas. Heat treatment process parameters: in the shaft furnace, a furnace is suspended with 4 pieces, the quenching heating temperature is 830±10℃, and after holding heat for 160min, it is divided into two times for quenching, and two pieces are quenched each time, and the circulating cooling water is used for cooling.

Why can't the hydraulic cylinder be replaced with water?
Hydraulic oil for hydraulic transmission has a variety of requirements for viscosity, density, flow rate, and temperature, which are not available for water.
