Dominica hydraulic cylinder,stainless steel cylinder manufacturer,stainless steel cylinder(Dominica stainless steel cylinder,produced by Hengyu Hydraulic Cylinder Factory)
stainless steel cylinder are widely used in Dominica,because of no transmission clearance,simple structure and reliable operation,excellent temperature resistance.So our company has designed stainless steel cylinder for customers from Dominica.
When the stainless steel cylinder needs to be stored for a period of time, please follow the recommended methods: The stainless steel cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the stainless steel cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil stainless steel cylinder should not be in direct contact with water vapor for a long time. The stainless steel cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the stainless steel cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the stainless steel cylinder Before working, the stainless steel cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the stainless steel cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.
stainless steel cylinders in series, parallel and series parallel. Series: In the stainless steel 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 stainless steel 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 stainless steel 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 stainless steel 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.
If it is found that the stainless steel cylinder lubrication is poor or the stainless steel cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the stainless steel cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the stainless steel cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the stainless steel cylinder center line. In this way, when the piston works in the stainless steel cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the stainless steel cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.
The assembly work of the stainless steel cylinder has a great impact on the quality of the stainless steel cylinder: each part must be carefully cleaned before assembly; To correctly install the sealing device everywhere: when installing the sealing ring, pay attention to its installation direction to avoid oil leakage due to installation, and its lip should be equipped with a pressure oil chamber. In addition, because it is a YX-shaped sealing ring, it is necessary to pay attention to distinguish between shaft and hole use, do not install wrong; Because the sealing device is matched with the sliding surface, an appropriate amount of hydraulic oil should be applied during assembly; The special wrench should be used when the threaded coupling is tightened, and the torque should meet the standard requirements; After the piston and piston rod are assembled, it is necessary to measure whether the coaxiality and straightness on the full length are out of whack. After assembly, there should be no blocking sensation and uneven resistance when the piston assembly moves.
What size of hydraulic cylinder is needed for 200 tons pressure? The pressure of the cylinder at work is determined by the load, and the pressure of the physical force is equal to the force divided by the area of action (that is, P=F/S). If you want to calculate the output force of the cylinder, you can calculate by the formula: Set the radius of the piston (that is, the cylinder) is R (unit mm) the radius of the piston rod is r (unit mm) the pressure level P (unit MPa) when working, then the thrust of the cylinder F push =3.14*R*R*P (unit N) the pull of the cylinder F pull =3.14* (R* R-R *R) *P (unit N) 100 tons of the cylinder, System pressure 16Mpa.
How does the clamping cylinder work?
Hydraulic transmission principle: oil as the working medium, through the change of the sealing volume to transfer movement, through the internal pressure of the oil to transfer power. 1. The power part - converts the mechanical energy of the prime mover into the pressure energy of the oil (hydraulic energy). For example: hydraulic pump. 2, The executive part - the hydraulic pump input oil pressure energy into the mechanical energy to drive the working mechanism. For example: hydraulic cylinder, hydraulic motor. 3, The control part - used to control and adjust the oil pressure, flow and flow direction. For example: pressure control valve, flow control valve and direction control valve. 4, The auxiliary part - the first three parts are connected together to form a system, which plays the role of oil storage, filtration, measurement and sealing.
