This article mainly introduces:
Holland hydraulic cylinder,servo cylinder manufacturer,servo cylinder
(Holland servo cylinder,produced by Hengyu Hydraulic Cylinder Factory）
servo cylinder are widely used in Holland，because of no need for deceleration device，long service life，smooth movement.So our company has designed servo cylinder for customers from Holland.
Regular maintenance of the servo cylinder includes: regular tightening, servo cylinder fastening screws and gland screws, servo cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the servo cylinder once a year. Clean regularly, the servo cylinder is cleaned every other year, and the seals are replaced while cleaning.
The commonly used buffer structure of the servo cylinder is composed of a piston boss and a servo cylinder head groove. When the piston moves close to the servo cylinder head, it gradually enters the groove, and the oil in the groove is extruded through the gap between the boss and the groove, which increases the oil return resistance, produces the braking effect and realizes the buffer. Generally, a buffer mechanism should be used when the pressure is above 10MP.
The advantages and disadvantages of the servo cylinder: the surface of the servo cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the servo cylinder through the top heat treatment, high manufacturing precision, belongs to the precision machinery, has a simple structure, stable quality, high mechanical efficiency, easy to achieve automation and many other advantages. However, hydraulic technology also has the shortcomings of oil leakage, oil temperature change affecting the control of running speed, noise, expensive cost and high maintenance cost.
In the hydraulic system, sometimes the inner layer of the rubber hose is peeled off, so that the oil circuit is on and off, resulting in irregular servo cylinder action. Troubleshooting method: Replace the rubber hose.
What is the difference between gas-hydraulic pressurized cylinder, pneumatic cylinder and oil cylinder?
The cylinder block is small and the force is large, constant speed and variable speed can be used (easy to change), the adjustment of the output is also convenient, and the freedom of transmission is high. However, maintenance costs and installation costs are high, and there is the trouble of mild oil pollution. Easy cylinder control, low price, easy access to energy. But the force is small, and can not achieve the effect of stable speed. The gas-liquid pressurized cylinder has the advantages of both of the above: environmental protection and energy saving, easy control, and simple adjustment. However, the output of the trip has certain restrictions, more suitable for short trips, large output, but also environmental protection and energy saving and low configuration of the occasion.
The pressure gauge of the hydraulic station reaches 20MPa. How many tons of weight can the hydraulic cylinder lift? How to convert?
20Mpa=200kg/cm^2 The weight of the cylinder with a cross-sectional area of 1 square centimeter can be lifted is 200kg, so F=200X3.14X (125/2) ^2 =24531kg =24.5 tons.
