tilting furnace hydraulic cylinder are widely used in Finland，because of no need for deceleration device，long service life，smooth movement.So our company has designed tilting furnace hydraulic cylinder for customers from Finland.
In use, the tilting furnace hydraulic cylinder should try to avoid the friction iron powder or iron filings formed by buffering the plunger. When the matching gap of the buffer device is small and the transverse load on the piston rod is large, the sintering phenomenon may be caused. These friction iron powder or the metal fragments that have fallen off as a result of sintering will remain in the tilting furnace hydraulic cylinder.
The wear of the hard chromium plating layer of the tilting furnace hydraulic cylinder is mostly caused by the grinding of the friction iron powder of the piston, and the wear is faster when there is water in the middle. Corrosion caused by the contact potential difference of the metal only occurs in the part of the piston contact, and the corrosion occurs in a point pattern. As mentioned above, when there is moisture in the middle, it will promote the development of corrosion. Compared with castings, the contact potential difference of copper alloy is higher, so the corrosion degree of copper alloy is more serious.
At the rated pressure, the thrust of the tilting furnace hydraulic cylinder is determined by what factors: at the rated pressure of the oil pump, the work done by the tilting furnace hydraulic cylinder is related to the diameter of the tilting furnace hydraulic cylinder, but not to the stroke of the tilting furnace hydraulic cylinder. Moreover, the larger the tilting furnace hydraulic cylinder diameter, the larger the area, and the greater the pressure obtained. To this point, we should have a correct understanding and clear understanding, so as to avoid problems in the use of the tilting furnace hydraulic cylinder.
Most of the failure of the tilting furnace hydraulic cylinder is because there is a foreign body in the tilting furnace hydraulic cylinder into the failure of the tilting furnace hydraulic cylinder, the most problematic is that it is difficult to determine when the foreign body is into the tilting furnace hydraulic cylinder. After a foreign body enters, if the outer side of the sliding surface of the piston is equipped with a seal with a lip edge, then the lip edge of the seal can scrape the foreign body when working, which is beneficial to avoid scratching. However, the piston equipped with 0-shaped sealing ring has a sliding surface at both ends, and foreign bodies are sandwiched between this sliding surface, which is easy to form scars.
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 factors does the movement speed of the cylinder in the hydraulic system depend on?
The hydraulic system should be the piston movement in the cylinder, and the speed should also be the speed of the piston, according to the piston speed formula: v=4qm/pai*(D^2-d^2) where q is the flow rate of the input hydraulic cylinder, m is the volumetric efficiency of the hydraulic cylinder, D, d is the diameter of the piston and piston rod, because other factors are determined, the movement speed of the cylinder depends on the flow rate.
