Basic Introduction to Scissor Arm Hydraulic Cylinder

Scissor arm hydraulic cylinder: To ensure the service life of the hydraulic cylinder, impurities and dirt must not be mixed in the medium used, in order to avoid scratching the inner arm of the cylinder, causing damage to the seal, and causing leakage inside the hydraulic cylinder. The system is required to have a filtration accuracy of no less than 80 μ m, strictly control oil contamination, maintain the cleanliness of hydraulic oil, regularly check the performance of hydraulic oil, and perform necessary fine filtration or replace with new working hydraulic oil. Hydraulic cylinders are mainly composed of cylinder barrel, piston, piston rod, cylinder head, cylinder bottom, piston rod head, and related auxiliary devices. The piston divides the cylinder into two chambers, left and right, and uses the action of pressure oil to perform reciprocating motion inside the cylinder. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage. At the location where the piston rod passes through the cylinder head, due to the existence of a gap, external leakage is prone to occur, and dust can enter the cylinder through this gap. Therefore, a sealing device and dust-proof factor are installed. At the same time, in order to eliminate the influence of eccentric load on piston operation, all hydraulic cylinders must be equipped with a guide sleeve of considerable length at the extended end of the piston rod. In addition, when the piston moves at a fast speed, there is a serious mechanical collision between the piston and the cylinder bottom and cylinder head. Therefore, buffer deceleration piston type oil cylinders should be installed at both ends of the hydraulic cylinder, which are widely used in hydraulic transmission. When this type of oil cylinder works, it mainly delivers hydraulic oil alternately to both sides of the piston in the cylinder, and uses the pressure difference between the hydraulic oil on both sides of the piston to achieve the reciprocating motion of the piston. If you want to accelerate the forward speed of the piston, you can control the return oil in the cylinder through a valve and directly input it into the inlet pipe to participate in pushing the piston and achieve rapid movement of the piston, but the thrust of the piston is greatly reduced. Before disassembling the oil cylinder, the system should be unloaded, the circuit pressure should be zero, the oil source should be cut off, the oil port piping should be loosened, and the oil port should be blocked. The assembly of oil cylinders has a significant impact on their quality: each component must be carefully cleaned before assembly; To install the sealing device correctly: When installing the sealing ring, pay attention to its installation direction to avoid oil leakage due to installation, and its lip should face the pressurized oil chamber. In addition, as it is a Yx shaped sealing ring, it is important to distinguish whether it is for shaft or hole use and avoid installing it incorrectly; Due to the fit between the sealing device and the sliding surface, an appropriate amount of hydraulic oil should be applied during assembly; When tightening threaded connectors, a special wrench should be used, and the torque should meet the standard requirements; After assembling the piston and piston rod, it is necessary to measure their coaxiality and straightness along the entire length to ensure that they do not exceed the tolerance; After assembly, there should be no obstruction or uneven resistance when the piston component moves.

Reference price for hydraulic cylinder of scissor arm

The factory price of the scissor arm hydraulic cylinder is determined by factors such as usage environment, technical requirements, stroke range, and operating speed. Whether synchronization is required or not varies, and the cost also varies. The cost of common brands of scissor arm hydraulic cylinders ranges from 1400/yuan to 90000/yuan.

Maintenance and related issues of hydraulic cylinder for scissor arm

• What is the smallest cylinder model?
  The smallest hydraulic cylinder I have ever seen is the hydraulic clamping cylinder in the machine tool industry. The outer diameter is 24 millimeters, the total length is 23 millimeters, and the stroke is 4 millimeters. Weight 0.05 kilograms. The maximum clamping force is 3500 Newtons. There is no universal model in Germany. The price is 700 yuan.
• What brand is the best for hydraulic cylinder sealing rings
  It depends on the specific product. World renowned sealing brands include NOK, CFW, PARKER, TSS, WKF, DINGZING DZ, ASTON, HALLITE, TECNOLAN, and so on.
• When calculating hydraulic cylinders, the allowable stress of the material [б]=б/n. How to select the safety factor?
  On typical oil cylinder samples, there are the cylinder diameter, rod diameter, and maximum stroke of the oil cylinder. Then there will be an outer diameter on the diagram, which will indicate the wall thickness. There are various pressures. All are standard, refer to them for yourself.
• What does st mean in the hydraulic cylinder formula
  St is the original unit of kinematic viscosity, abbreviated as Stokes, also known as Stokes. We have now switched to cm2/s. 1 St=10 ^ -4m2/s
