Gypsum Grinding Machine troubleshooting

Guide: As a new type of environmentally-friendly and energy-saving grinding equipment, Gypsum Grinding Machine is favored and widely used in cement production. However, due to the fact that the technology of Gypsum Grinding Machines in China is not mature enough, there will be more or less failures in use, such as hydraulic tensioning failures. Shibang after-sales maintenance technicians explain the root causes of hydraulic strainer failure of Gypsum Grinding Machines and find out the reasons to completely solve them.

Gypsum Grinding Machine hydraulic tensioning system failure:

The Gypsum Grinding Machine will have some problems during the specific use, resulting in unnecessary economic losses. One of the common and most influential faults is the hydraulic tensioning system failure, which specifically includes the frequent start failure of the high pressure oil pump of the hydraulic station, the strain and oil leakage of the hydraulic cylinder and the damage of the accumulator airbag.

Root cause of hydraulic tensioning system failure of raw material Gypsum Grinding Machine:

The first type of failure is an accumulator airbag breakage failure. The accumulator plays the role of energy storage, pressure holding and shock absorption in the hydraulic system of the Gypsum Grinding Machine. However, if the Gypsum Grinding Machine is unstable, the stretching rod will frequently cause the nitrogen balloon to shrink frequently or even burst. The simple way to judge this fault in actual production is to rely on the experience of the operator and the test of the instrument. If the hand accumulator is citrus to hot or below the oil temperature, the bottom is accompanied by a knocking sound, indicating that the accumulator is faulty. I want to fix it now.

The second type of failure is a frequent start failure of the high pressure oil pump at the hydraulic station. If the hydraulic system pressure cannot be maintained during the operation of the Gypsum Grinding Machine, and the high pressure oil pump is frequently started, the hydraulic oil temperature rises, indicating that the oil pump is damaged and the energy consumption is increased. Experience can be seen, there are two reasons for this failure: First, the hydraulic rod of the hydraulic cylinder is damaged by the seal of the rod, and the second is the leakage or damage of the return valve.

The third type of failure is a hydraulic cylinder block strain or oil leakage failure. The possible causes of this failure are: the entry of impurities into the hydraulic oil; the top is inclined, and the fine-grained material is caught between the hydraulic cylinder and the piston rod, causing longitudinal wear marks on the surface, the oil seal is damaged, causing oil leakage; the hydraulic cylinder seal ring is aging; The setting of the grinding force is unreasonable, and the setting tension is too high, resulting in the oil pressure in the hydraulic cylinder continuing to be high, causing this failure.

Gypsum Grinding Machine hydraulic tensioning system failure “big sweeping”:

In terms of damage to the accumulator airbag, the fundamental measure is to stabilize the running condition of the Gypsum Grinding Machine and avoid the violent vibration of the equipment. In addition, a reasonable method of nitrogen filling is also a reason to avoid bursting of the nitrogen balloon. Generally, the inflation pressure is controlled at the system working pressure.

For the frequent start failure of the high pressure oil pump of the hydraulic station, the following measures can be taken: First, check the hydraulic cylinder for internal leakage, if it should be replaced in time; secondly, determine the setting range of the tension force, usually according to the material. Easy to grind to determine; third is to check and clean your hydraulic valve to prevent debris and dirt.

In terms of hydraulic cylinder block strain or oil leakage failure, the first thing to do in production is to ensure the high level of hydraulic oil cleaning. The second is to prevent fine particles from entering the cylinder. It is recommended to make a soft external. The connection sheath is used for protection. The third is that the use of hydraulic oil should be regularly tested for high quality, and new hydraulic oil should be replaced in time. The fourth is to set a reasonable grinding force according to the hardness of the material.

In short, the correct use and maintenance of the hydraulic system of the Gypsum Grinding Machine not only ensures the safety and stability of the Gypsum Grinding Machine operation, but also helps to reduce the failure rate and improve the grinding efficiency, thereby realizing the benefits.
