Analysis of common failures of shears
Author : admin Time : 20-10-26 AllPageView : 353

In daily life,no matter how good the equipment is,if there is no good sense of inspection and maintenance, t will affect the efficiency of the machine over time.

Like the scrap baler,the shearing machine also often causes frequent damage due to its high working intensity.

Everyone knows that the nature of the metal,the shearing temperature and other factors will affect the shearing quality of the shearing machine.To a large extent,the lack of maintenance and maintenance awareness will cause some unnecessary troubles.

We have classified the failures of the shearing machine in daily use:the oil cylinder,the oil pump,and the cutting blade.

1.In terms of oil cylinder:After the machine is powered on,the oil cylinder cannot generate pressure.At this time,it is because the oil contains impurities in the process of sucking oil for a long time,which causes the overflow valve to block.

2.Oil pump:After the machine is started,if the oil pump does not work,check the electromagnet or replace the electromagnet.It is very likely that the electromagnet loop fails due to long-term use and cannot generate magnetic force;

Or the spool is stuck due to dust entering the steering valve spool,causing the oil pump to fail to work.

3.In terms of cutting edge:Too high or too low cutting edge will result in non-standard distance between the blade gap.During the cutting process,the cut material will be irregular and the quality is poor.

The above 3 points are that you have encountered more in the process of use.Others include failures such as insufficient oil and air supply due to the rupture of the oil suction pipe.

These are things that everyone should always pay attention to during use.Only by mastering these common faults,we will be more comfortable when using the shearing machine.

According to the actual needs of everyone,the Nick brand shearing machine has been recognized by many customers with high-quality qualifications and professional craftsmanship and is trustworthy.

  • The solution to the pressure-free hydraulic system of the waste paper baler

    Common failure phenomenon: the entire hydraulic system of the waste paper baler has no pressure or insufficient pressure.

    Common causes of failure: the overflow valve fails, and the oil pump is not working properly.

    Solution: Check the type of overflow valve used in the waste paper baler equipment. If it is a pilot-operated overflow valve, there are many causes.

    1. The overflow valve is stuck or the solenoid fails. If the overflow valve is stuck, clean the overflow valve and reinstall it. If it is electromagnetic failure, you need to check whether the circuit is open, and check whether the coil of the overflow valve is burned. If there is a problem with the circuit, repair the circuit; if the coil burns out, the coil needs to be replaced.

    2. If it is the internal wear of the overflow valve, the overflow valve needs to be replaced at this time.

    Waste paper baler is an environmental protection equipment that uses hydraulic principles to compress waste paper and waste cardboard into blocks, which is beneficial to waste paper storage, transportation and utilization. https://www.nickbaler.net


  • The oil pump of the horizontal waste paper baler is overheated.

    The oil pump of the horizontal waste paper baler generally has a plunger pump and a vane pump. The reasons for the loud noise of the oil pump system may include: loosening of the fastening screws of the oil pump; wear of the power bearing or stator of the oil pump; serious damage to the oil pump; inside the oil tank Air bubbles, poor oil intake of the hydraulic pump and other reasons will cause this problem. At this time, we should analyze the specific situation and solve the problem of excessive noise in the hydraulic waste paper baler oil pump!

    The possible causes of the failure of the oil pump overheating problem are that the oil pipe is blocked, causing the pressure of the hydraulic oil to increase; the power of the oil pump is too large and overloaded; the hydraulic oil is used unreasonably and the viscosity is too high.

    The quality of the hydraulic oil of the hydraulic waste paper Baler has a great influence on the hydraulic pump. The replacement cycle of the plunger pump is generally one year. If the plunger pump is noisy, it is recommended to consider replacing the plunger pump plunger.

    The waste paper baler is used to extrude waste paper and similar products under normal conditions to greatly reduce the volume, so as to reduce the transportation volume, save the freight, and increase the benefits for the enterprise. https://www.nickbaler.net


  • The first refueling method of horizontal waste paper baler

    The method of refueling the newly purchased waste paper baler equipment before starting, and the oil leakage problem of the newly purchased horizontal waste paper baler equipment has been plagued by the majority of user groups, so how to solve the problem of the waste paper baler oil Well, let's take a look at the waste paper baler equipment with Nick Machinery. What should I pay attention to when using the refueling method?

    1. The oil leakage of the waste paper baler is relatively severe. If the oil pump pressure is adjusted too high, the wear of the movable parts will increase the sealing gap, the sealing device will be damaged, the viscosity of the oil used in the waste paper baler will be too low, etc., which will increase the leakage. After clarifying the reason, adopt the corresponding steps to eliminate it.

    2. 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.

    3. 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. 

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