Holland hydraulic cylinder,series synchronous cylinder manufacturer,series synchronous cylinder(Holland series synchronous cylinder,produced by Hengyu Hydraulic Cylinder Factory)
series synchronous cylinder are widely used in Holland,because of no need for deceleration device,long service life,smooth movement.So our company has designed series synchronous cylinder for customers from Holland.
The daily inspection of the series synchronous cylinder includes: checking the connection of the series synchronous cylinder and the pipe joint for leaks. Check the series synchronous cylinder rod for leaks. Check the series synchronous cylinder connection for leaks. When the series synchronous cylinder moves, the work is normal and smooth. Whether the series synchronous cylinder has internal leakage.
When installing the series synchronous cylinder, the axial ends of the series synchronous cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the series synchronous cylinder, there is axial expansion. If the two ends of the series synchronous cylinder are fixed, all parts of the series synchronous cylinder will be deformed. When disassembling the series synchronous cylinder, it is strictly forbidden to hammer the series synchronous cylinder and the piston surface, such as the series synchronous cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.
The coordination of the sliding parts of the series synchronous cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.
If air enters the hydraulic system, the series synchronous 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.
Why the cylinder cannot operate normally after the explosion-proof valve is installed?
The pipeline explosion-proof valve is specially designed to prevent pipeline damage and free fall of the cylinder, so there must be back pressure to open. If there is no oil return pressure, or the oil return pressure is too small, and can not adjust the oil return pressure, such a system with explosion-proof valves is more troublesome, it is recommended to add a one-way throttle valve between the cylinder and the tank to establish back pressure. If you understand the explosion-proof valve, you can also try to adjust the opening of the valve (that is, the flow of the regulating valve), and adjust the opening to help the valve to open.
Hydraulic cylinder application areas?
1, in the machine tool industry, 85% of the machine tool transmission system adopts hydraulic transmission and control. Such as grinding machine, milling machine, planer, broaching machine, press, shearing machine, and combined machine tools. 2, in the metallurgical industry, electric furnace control system, rolling mill control system, open furnace charging, converter control, blast furnace control, strip deviation and constant tension device are all using hydraulic cylinders. 3, in the construction machinery, the general use of hydraulic transmission, such as excavators, tire loaders, truck cranes, crawler bulldozers, tire cranes, self-propelled scrapers, graders and vibration rollers. 4, in agricultural machinery, the use of hydraulic cylinders is also widely used, such as combine harvesters, tractors and so on.
