Abnormal phenomenon of waste paper baler
Author : admin Time : 21-04-26 AllPageView : 189

Nick Machinery's automatic horizontal waste paper baler is guided by the national environmental protection policy, and the abnormal phenomena that may occur in the work of the automatic horizontal waste paper baler:

1. After the engine of the automatic horizontal waste paper baler is started, if the reading of the oil pressure gauge pointer gradually drops, or even drops to zero. It indicates that the main bearing bush and connecting rod bearing of the crankshaft are severely worn, which makes the matching clearance too large, or the pressure limiting valve and the oil return valve are severely worn, and the sealing is not tight, causing the oil to flow back to the oil pan. 

2. When the engine of the automatic horizontal waste paper baler is working, the pointer of the oil pressure gauge swings from side to side. The reason is mostly that the valve seat of the oil return valve is not correct, the spring is skewed, or the pressure of the oil return valve is low. When the oil pressure is slightly higher, the valve opens, the oil pressure drops sharply, and the valve closes again. In this way, the oil return valve is repeatedly opened and closed, causing the oil pressure of the waste paper baler to rise and fall, causing the pointer of the oil pressure gauge to swing left and right.  

3. The oil pressure of the automatic horizontal waste paper baler is normal when the engine is low speed, and the oil pressure is low when the speed is high. The reason is that the return valve spring is stuck. The valve is closed when the speed is low, and the oil pressure value of the waste paper baler is normal; when the speed is high, the oil pressure of the waste paper baler suddenly opens, and the oil pressure drops accordingly, and the spring cannot reduce the valve in time. The opening degree makes the oil pressure of the waste paper baler low.  

4. The oil leakage ratio of the automatic horizontal waste paper baler is severe. If the oil pump pressure is adjusted too high, the wear of the movable parts will cause the sealing gap to increase continuously, the sealing device will be damaged, the viscosity of the oil used in the waste paper baler is too low, etc., will increase the oil leakage.


5. The system does not have an unloading circuit or the unloading circuit does not perform well. When the waste paper baler system does not need to pressurize the oil, the oil is still overflowing to the fuel tank under the working pressure set by the overflow valve or at the unloading pressure Return to the fuel tank downstream in a higher environment. It is necessary to check whether the unloading circuit is normal or not, and adopt the corresponding steps to eliminate it.  

6. Poor heat dissipation, insufficient heat dissipation area of ??the fuel tank, too little oil storage in the fuel tank, resulting in too fast oil circulation, poor cooling of the waste paper Baler cooler, such as failure of cooling water supply or failure of electric fans, high ambient temperature, etc. All are the reasons for poor heat dissipation.  

7. Misuse of oil with too high viscosity, the waste paper baler will cause excessive hydraulic loss.  

The abnormal phenomenon of the automatic horizontal waste paper baler is that when the machine is just started, as the machine oil temperature rises, the oil viscosity will gradually decrease, and the oil pressure gauge pointer will gradually fall and stabilize within the specified range. This phenomenon also shows that the lubrication system of the automatic horizontal waste paper baler is normal.

Nick Machinery has rich production experience and integrated service. Using the baler produced by Nick Machinery can improve work efficiency and reduce human and financial expenditure.

  • Saudi tire balers market

    Customers can choose their own models according to their actual conditions. Tire balers are now in a situation where all kinds of tire balers coexist in the market. Because of its significant advantages, tire balers are increasingly occupying a larger market mainstream.

    The tire baler equipment is also being updated from time to time, and technology is advancing. For example, the tire balers were also manually tightened from the beginning. Later, the tire balers have been developed into the fully-active computer-controlled balers with active rope ties in recent years, and they have quickly become the mainstream in the shopping malls, used tire balers, So what are the advantages of tire balers;

    Because automatic production also reduces many disadvantages caused by human operation, manual and semi-active balers can significantly improve production efficiency compared with fully-active tire balers. It also reduces the labor intensity of workers.

    The volume of the material is greatly reduced, and the density of the bale produced by the tire baler is greater. This saves shipping costs. Customers who have used both generations of equipment should have a deep understanding.

    Due to the hydraulic system used by the tire balers, the package appearance is more neat. The tire balers can also enhance our company's technical strength and corporate image.

    The tire baler is not easy to be scattered during loading, unloading and transportation, because the density of waste products packed into the tire baler is high. Will not pollute the environment.

    The tire baler saves electricity bills. Greatly reduce the energy consumption of the equipment.

    In the future, NKBALER will continue to research and innovate rubber tire balers to serve consumers better and more assuredly.

  • Operation matters of Myanmar straw baler

    Grasp the hydraulic principle of the straw baler, know which spool must be closed and which spool must be opened in a specific operation. If the closed spool cannot be completely closed, the opened spool cannot be opened, which will inevitably cause the oil flow to go wrong and cause a hydraulic failure.

    As a qualified operator of the straw baler, we should master some operations of the straw baler during normal operation. The following are some of the contents we need to master.

    1. Familiar with the working steps of each working mechanism of the straw baler.

    2. Familiar with the position and function of each switch of the straw baler.

    3. Master the electric beat table of the electromagnet in each working step of the straw baler.

    4. Grasp the control principle of the opening and closing of the cartridge valve core of the straw baler.


    When a failure occurs, you cannot simply search for the cartridge valve part. The failure may also involve mechanical jamming, electrical part failure, and other hydraulic component failures. Therefore, when a straw baler failure occurs, a comprehensive and careful inspection must be performed to distinguish the type of failure (mechanical, electrical, and hydraulic) in order to quickly eliminate the failure. In the process of troubleshooting the hydraulic failure, do not install the object wrongly or reversely. Otherwise, not only the fault cannot be eliminated, but also the fault becomes difficult to judge.
