Finland hydraulic hollow cylinder

(Finland hydraulic hollow cylinder,produced by Hebei Hengyu company)

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

Introduction to hydraulic hollow cylinder:

Because of the slightly complex structure of the buffer hydraulic hollow cylinder, sometimes there will be problems, such as when the hydraulic hollow cylinder with the buffer device is started in reverse, the piston often stops temporarily or reverses. Elimination method: The orifice of the check valve is too small, so that the amount of oil entering the buffer chamber is too small, and even a vacuum occurs, so the above fault phenomenon will occur when the buffer plunger leaves the end cover. In this regard, the orifice of the check valve should be increased.

hydraulic hollow cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the hydraulic hollow cylinder head itself is the guide sleeve of the piston rod, the hydraulic hollow cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the hydraulic hollow cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.

If air enters the hydraulic system, the hydraulic hollow 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.

The cavitation of the hydraulic hollow cylinder has a great influence, and to avoid it, it is necessary to use the hydraulic oil reasonably and ensure the quality of the hydraulic oil. If the anti-foam property of the oil is poor, it is easy to produce foam, resulting in cavitation. Secondly, the change frequency of oil pressure is too fast and too high, which will also directly cause the formation of bubbles and accelerate the rupture rate of bubbles. The test shows that the speed of cavitation will be accelerated in the part with high frequency of pressure change. For example, at the inlet and outlet of the hydraulic hollow cylinder, due to the relatively high frequency of pressure changes, the degree of cavitation is also relatively higher than that of other parts. In addition, overheating of the oil will also increase the probability of cavitation.

Answers to some questions about hydraulic hollow cylinder:

How many tons is the oil cylinder 16mpa?
It depends on the cross-sectional area of the cylinder A(mm2)F=16mpa×A unit is (tons).

How to calculate the tonnage of hydraulic cylinder? The tonnage of the cylinder refers to the output force of the cylinder under rated working pressure: 1, for single rod piston hydraulic cylinder, it can be calculated by the area of the circle corresponding to the inner diameter of the cylinder A (square centimeter), and the rated working pressure of the system p (mpa), the value is equal to 10pA kg force, and the ton is 0.01pA. 2, for the double rod piston hydraulic cylinder, with A(square centimeter) to indicate the cylinder cylinder diameter and piston rod outer diameter defined by the ring area, with p (mpa) to indicate the rated working pressure of the system, the output force of the cylinder is 0.01pA ton force.
