  • Analysis and elimination of common faults in hydraulic cylinders

    Among the many causes of hydraulic cylinder failure, improper installation, use, and maintenance are important causes of failure.
    2 Why is the hydraulic cylinder not sensitive (blocking), how to eliminate it?

    The hydraulic cylinder is not sensitive to the movement of the hydraulic cylinder. This phenomenon means that the hydraulic cylinder cannot be operated immediately after the instruction of the hydraulic cylinder is issued, and it takes a short time to operate, or it can be stopped when it is moving, and the operation is very irregular. The main causes and troubleshooting methods for this fault are:

    1) There is air in the hydraulic cylinder. Remedy: Exhaust through the exhaust valve. Check the seal ring at the reciprocating part of the piston rod for air inhalation. If so, replace the seal.

    2) There are irregularities in the operation of the hydraulic pump, and the pump rotation has a block or a slight seizure. Remedy: According to the type of hydraulic pump, according to the reasons for its failure, solve the problem separately. For details, please refer to the relevant information.

    3) When the hydraulic cylinder with the buffer device is started in reverse, the piston temporarily stops or reverses. Remedy: The orifice of the check valve is too small, so that the amount of oil entering the buffer chamber is too small, and even a vacuum occurs, so the above-mentioned failure phenomenon occurs when the buffer plunger leaves the end cap. In this regard, the orifice of the check valve should be enlarged.

    4) When the piston movement speed is high, the steel ball of the check valve follows the oil flow, so that the valve hole is blocked, and the hydraulic cylinder causes the movement to be irregular. Remedy: Replace the steel ball with a poppet or spool with a guide shoulder.

    5) The inner layer of the rubber hose is peeled off, so that the oil passage is broken and the hydraulic cylinder is irregularly moved. Remedy: Replace the rubber hose.

    6) The hydraulic cylinder is subjected to a certain lateral load. Remedy: Same as the method of "the hydraulic cylinder can't move".

  • Among the many causes of hydraulic cylinder failure, improper installation, use, and maintenance are important causes of failure.
    1 Why can't the hydraulic cylinder move? How to eliminate it?

    1) The resistance to perform moving parts is too great. Remedy: Exclude problems such as jamming and wedge tightening in the actuator; improve the guiding and lubrication state of the moving parts.

    2) The oil pressure at the inlet is too low to reach the specified value. Remedy: Check the leakage of the oil circuit system and eliminate the leakage; check the seal of the piston and the piston rod for damage, aging, looseness, etc.; check whether the hydraulic pump and pressure valve are faulty.

    3) The oil does not enter the hydraulic cylinder. Remedy: Check whether the oil pipe, oil circuit, especially the hose joint has been blocked, check the relevant oil circuit from the cylinder to the pump and remove the blockage; check whether the seal between the cone valve and the valve seat of the overflow valve is good; Check if the solenoid spring is damaged or the solenoid coil is burnt out; if the oil circuit is switched, it is not sensitive.

    4) The cooperation of the sliding parts of the hydraulic cylinder itself is too tight, and the sealing friction force is too large. Remedy: H8/f8 should be used between the piston rod and the guide sleeve; check whether the size of the seal is strictly processed according to the standard; if the V-shaped seal is used, the seal friction should be adjusted to a moderate level.

    5) Due to improper design and manufacture, when the piston returns to the end point, the effective working area of the piston acting on the piston is too small. Remedy: Improve design and remanufacture.

    6) The lateral load of the piston rod is too large, especially the cylinder or the cylinder. Remedy: When installing the hydraulic cylinder, ensure that the axis position of the cylinder is consistent with the moving direction; make the load of the hydraulic cylinder pass through the cylinder axis as much as possible to avoid eccentricity; when the long hydraulic cylinder rotates horizontally, the piston rod is deflected by its own weight, so that The guide sleeve and the piston produce partial load, which causes the cylinder head seal to be damaged and oil leakage. The piston sleeps in the cylinder. The following measures can be taken: increase the piston plan to adjust the piston outer circle to form a drum convex shape, so that the piston can self-position Improve the stress condition to reduce and avoid the pull cylinder; the connection between the piston and the piston rod uses a ball joint.

    7) The back pressure of the hydraulic cylinder is too large. Remedy: Reduce back pressure. An important reason why the hydraulic cylinder cannot operate is that the oil pressure at the inlet is too low, that is, the working pressure is insufficient. The reasons for the insufficient working pressure of the hydraulic system are mainly the failure of the hydraulic pump, the drive motor and the pressure regulating valve. Other reasons are: oil filter blockage, oil passage diameter is too small, oil viscosity is too high or too low; oil Excess air is introduced into the liquid; the pollution is serious; the pipeline is connected incorrectly; the pressure gauge is damaged.
  • The benefits of silage corn stalk balers can increase the income of farmers and benefit the country and the people.

    First, Silage corn straw baler helps to reduce environmental pollution and protect the ecological environment. The thick smoke formed by the burning of crop straws will release carbon dioxide and sulfur dioxide, which will cause environmental pollution, affect air quality and damage the health of the people. Increasing the comprehensive utilization of crop straw can improve the comprehensive utilization rate of straw, effectively reduce straw burning, prevent straw from polluting water sources, and protect the ecological environment.

    Second, Silage corn straw baler will help to increase the value of straw utilization and develop a circular economy. Crop straw is an important biomass resource. It is widely used as a substitute for coal, electricity, oil, gas and other energy sources. It can also be used as feedstock, fertilizer, edible fungus base, and as an industrial raw material. Strengthening the comprehensive utilization of straw can reduce the consumption of other resources, promote the sustainable use of resources, and promote the development of circular economy.

    Third, Silage corn straw baler will help improve the arable land and enhance the comprehensive agricultural production capacity. Straw returning has the functions of increasing fertilizer, changing soil and protecting soil, which can increase soil organic matter and degrade pesticides and heavy metals in soil. Studies have shown that a certain amount of straw per mu of cultivated land can not only increase grain yield, but also significantly improve soil physical and chemical properties and improve soil fertility.

    Fourth, Silage corn straw baler will help improve agricultural efficiency and increase farmers' income.
  • The overall technology of hydraulic packaging machinery in China is still not perfect, but the market demand for hydraulic packaging machinery in China is very large, which greatly promotes the development of the hydraulic baler industry, and also promotes the continuous self-innovation of production enterprises, greatly changing the backwardness.
