In order to adapt to the farm development of society and improve work efficiency, the current AG machinery and equipment are becoming larger and larger, and the efficiency is getting higher and higher.
In order to adapt to the farm development of society and improve work efficiency, the current AG machinery and equipment are becoming larger and larger, and the efficiency is getting higher and higher. These large machines can complete work efficiently, without their core components, tractor loader hydraulic cylinders, and many gravity forces. All of the machinery must use tractor front loader hydraulic cylinders as the core of power transmission, and these tasks can only be completed with the help of farm hydraulic cylinders.

FAQ
East Timor customers consulted with us about Tractor Front Loader Hydraulic Cylinder
Q: Hydraulic cylinder thrust calculation
A: Hydraulic cylinder inner diameter = piston diameter = 200MM piston area = π (200 / 2) square = 3140 square mm = 31.4 square centimeter 25MPA = 250KG / square centimeter maximum thrust = pressure * piston area = 250 * 31.4 = 7850KG = 78500 Newton This is the maximum thrust.
Q: PLC+inverter+motor+pump+solenoid valve+cylinder combination can control the position accuracy of the cylinder?
A: 1. Hydraulic oil can be compressed. It is elastic like a spring. Therefore, in a general hydraulic servo system, the valve control is much more accurate than the pump control. Because the valve can be mounted close to the hydraulic cylinder, even on the hydraulic cylinder, the pump must pass through the oil pipe and then enter the hydraulic cylinder, which has a long distance, which greatly reduces the rigidity of the system and increases the difficulty of control. 2. The dosing pump is leaky first, and there is also a 10%-20% flow pulsation. Pump leakage is related to pressure and is non-linear.
Q: Hydraulic cylinder oil leakage
A: Several possibilities:
1. Between the piston rod and the guide sleeve:
(1) The hydraulic cylinder is not well stressed, and there is a radial force to cause an offset load between the piston rod and the guide sleeve, so that the oil seal is worn early and causes oil leakage.
(2) The ambient temperature of the piston rod is high, especially the radiant heat, and the oil seal aging is fast.
(3) Whether the oil seal is selected correctly; whether the oil seal is damaged during installation.
(4) Whether the tolerance between the guide sleeve and the piston rod is correct.
Second, between the guide sleeve and the cylinder: whether the O-ring on the guide sleeve is installed correctly, pay special attention to the O-ring can not be "rolled", especially some O-rings are closed and have a clamping line.
Third, the common problem: the guide sleeve, cylinder, piston rod concentricity. Fit tolerances are correct.
Q: Outdoor hydraulic cylinder working temperature?
A: Normal working temperature -30℃---100℃
