Ecuador disc spring hydraulic cylinder

(Ecuador disc spring hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)

disc spring hydraulic cylinder are widely used in Ecuador,because of long service life,smooth movement,no need for deceleration device.So our company has designed disc spring hydraulic cylinder for customers from Ecuador.

Introduction to disc spring hydraulic cylinder:

If air enters the hydraulic system, the disc spring 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.

The piston rod of the disc spring hydraulic cylinder has two kinds of solid rod and hollow rod, and one end of the hollow piston rod needs to be set aside for welding and heat treatment. The solid piston rod material is 35, 45 steel, and the hollow piston rod material is 35, 45 seamless steel pipe. After rough machining, the piston rod is conditioned to 229~285HB in India, and if necessary, the hardness is 45~55HRC after high-frequency quenching.

There are some honeycomb holes in the inner wall of the disc spring hydraulic cylinder, piston or piston rod surface. How is this formed? When we repair the disc spring hydraulic cylinder, we can see that there are some honeycomb holes on the inner wall of the disc spring hydraulic cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the disc spring hydraulic cylinder is targeted to prevent. Is very necessary.

Before the disc spring hydraulic cylinder is removed, the system should be unloaded, the loop pressure is zero, the oil source should be cut off, and the oil port should be blocked after the oil port distribution pipe is loosened.

Answers to some questions about disc spring hydraulic cylinder:

When the cylinder is tested, why can't the pressure be maintained with the balance valve?
Because the oil into the oil chamber through the hydraulic lock on the control oil circuit through the other side of the spool, the original valve is designed in this way. It locks the circuit after the oil supply circuit loses pressure, on the contrary, if you keep supplying pressure, it is always in the state of opening the other side of the one-way spool. So this valve can't be used in the test.

What is the function of the hinged cylinder of the shield machine?
The articulated cylinder is used for the shield when the radius of curvature is very small during the propulsion process, that is, for turning. For example, a propulsion section with a radius of curvature of R150 can only be turned using an articulated system due to the sensitivity of the shield body (i.e. the length of the shield body divided by its outside diameter). However, in the construction process, the use of articulated systems is not much.
