(Nepal hoister hydraulic cylinder,produced by Hebei Hengyu company）
hoister hydraulic cylinder are widely used in Nepal，because of excellent temperature resistance，powerful torque，no transmission clearance.So our company has designed hoister hydraulic cylinder for customers from Nepal.
The viscosity of the working oil used in the hoister hydraulic cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.
hoister hydraulic cylinder to reasonable use of hydraulic oil: strict hydraulic oil selection off. Hydraulic oil is selected in strict accordance with oil standards. The selection of good quality hydraulic oil can effectively prevent bubbles in the working process of the hydraulic system. When choosing the oil, it should be selected according to the lowest temperature in different regions, and fill the hydraulic oil according to the dipstick standard, and at the same time, it should also keep the hydraulic system clean (when filling the hydraulic oil, it should prevent the water and other impurities into it), and often check the oil quality, oil level and oil color of the hydraulic oil. If blisters and bubbles are found in the hydraulic oil. When the oil becomes milky white, the source of the air in the oil should be carefully found and eliminated in time.
When the hoister hydraulic cylinder is installed, the piston and the hoister hydraulic cylinder head and other parts have large mass, large size and large inertia, even if there is a lifting equipment auxiliary installation, because the specified clearance is small, no matter how hard it will be put into, therefore, the end of the piston or the hoister hydraulic cylinder head boss is easy to cause scars when it hits the inner surface of the hoister hydraulic cylinder wall. The solution to this problem: for a large number of small products, the use of autocratic assembly oriented tools during installation; For heavy, thick and large large and medium-sized hoister hydraulic cylinders, only careful and careful operation can be avoided.
The hoister hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating motion (or swinging motion). It is simple in structure and reliable in operation. When it is used to achieve reciprocating movement, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth, so it is widely used in various mechanical hydraulic systems. The output force of the hoister hydraulic cylinder is proportional to the effective area of the piston and the pressure difference between the two sides; The hoister hydraulic cylinder is basically composed of hoister hydraulic cylinder and hoister hydraulic cylinder head, piston and piston rod, sealing device, buffer device and exhaust device. Buffer device and exhaust device depending on the specific application, other devices are essential.
Is there a national standard for the testing of hydraulic cylinders?
Generally speaking, the cylinder test is carried out according to JB/JQ20302 Allowable leakage of cylinder in pre-factory leakage test. GB2879 hydraulic cylinder piston and piston rod dynamic seal groove type, size and tolerance. GB6578 hydraulic cylinder piston rod dust ring groove type, size and tolerance. GB7938 hydraulic cylinder and cylinder nominal pressure series, etc.
What is the HS code of the hydraulic cylinder?
HS code of hydraulic cylinder; 8412210000 8412210000 Linear hydraulic power unit (hydraulic cylinder) 0.12000 0.35000 0.00000 0.17000 0.00000
