metallurgical cylinder are widely used in Qatar，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed metallurgical cylinder for customers from Qatar.

Introduction to metallurgical cylinder:

metallurgical cylinders in series, parallel and series parallel. Series: In the metallurgical cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Series: In the metallurgical cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Parallel: the pressure oil in the metallurgical cylinder is connected with the inlet oil of each reversing valve, and the return oil is collected by the return oil circuit. Series parallel: For this one, compared with the simple series and parallel, it is slightly more complicated, but it is not impossible to understand. The series refers to the oil in the metallurgical cylinder, which is in series form, but can not form a series circuit, and the parallel refers to the oil return circuit of each valve, which is in parallel.

metallurgical cylinder spool stuck or valve hole blocked How to solve: When the flow valve or direction valve spool stuck or valve hole blocked, the metallurgical cylinder prone to misoperation or action failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium.

When installing the metallurgical cylinder, the axial ends of the metallurgical cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the metallurgical cylinder, there is axial expansion. If the two ends of the metallurgical cylinder are fixed, all parts of the metallurgical cylinder will be deformed. When disassembling the metallurgical cylinder, it is strictly forbidden to hammer the metallurgical cylinder and the piston surface, such as the metallurgical 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 body of the metallurgical cylinder on the processing process requirements: the body of the metallurgical cylinder is an important and essential part of the metallurgical cylinder, because it has an irreplaceable role. The processing requirements for this part are very high, requiring that the surface roughness of the metallurgical cylinder after processing should reach 0.4-0.8um, and the coaxiality and wear resistance requirements are also very high.

Answers to some questions about metallurgical cylinder:

Why does the hydraulic cylinder go up to the top and then slowly go down?
Leakage in the cylinder or the hydraulic valve that controls the cylinder, can be replaced and removed. Or add a pressure retaining valve to the hydraulic system to ensure pressure.

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.
