Nigeria hydraulic cylinder,steel mill cylinder manufacturer,steel mill cylinder

(Nigeria steel mill cylinder,produced by Hengyu Hydraulic Cylinder Factory）

steel mill cylinder are widely used in Nigeria，because of no need for deceleration device，no transmission clearance，excellent temperature resistance.So our company has designed steel mill cylinder for customers from Nigeria.

Introduction to steel mill cylinder:

Before the steel mill 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.

steel mill cylinder body inspection: The inner surface of the steel mill cylinder and the piston seal are the main factors causing the leakage in the steel mill cylinder, if the steel mill cylinder has a longitudinal tensile mark, even if the new piston seal is replaced, it can not effectively eliminate the fault, the inner surface of the steel mill cylinder mainly checks whether the dimensional tolerance and shape and position tolerance meet the technical requirements, there is no longitudinal tensile mark, and measures the depth of the longitudinal tensile mark, in order to take the corresponding solution.

The oil steel mill cylinder is a part of the hydraulic system, in the hydraulic system, to reasonably design the heat dissipation system, to prevent the oil temperature is too high is the key to keep the hydraulic oil temperature normal. The temperature of the system should be kept in a suitable range to reduce the energy released when the bubble bursts. While not affecting the normal circulation of the coolant, a certain amount of anti-corrosion additives can be appropriately added to inhibit rust. When operating the hydraulic system, we should strive to be stable, not too fast, too strong, and try to reduce the impact of hydraulic oil on hydraulic components.

When the control pressure of the hydraulic system is too low, the steel mill cylinder will appear wrong or no action, because the throttle resistance in the control pipeline may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is interfered with. At this time, check the control pressure source to ensure that the pressure is adjusted to the specified value of the system.

Answers to some questions about steel mill cylinder:

Need a hydraulic cylinder, vertical upward 10 seconds to lift 20 tons of weight up 2 meters, how large cylinder and rod, how much pressure to use the plunger pump and how big?
The first thing to determine the system pressure, let's say 25 mpa, can take into account cost and performance. 1 Cylinder area 20000/250=80 square cm cylinder diameter (80/3.14) squared x2=200 mm 2 cylinder volume 80x200=16000 ml =16 L 3 Required pump flow 16x60/10=96 L/min 4 Power 96x25/55=43 kW 45 kW motor is available.

What is the main maintenance of the cylinder?
After disassembling the cylinder: 1, clean the cylinder and piston; 2, replace all seals; 3, if there is a valve to repair, to ensure sealing and flexible; 4, deal with all deformation parts; 5. Installation experiment.
