After-sales maintenance personnel of hydraulic shears can use accumulated experience and solid theoretical knowledge, combined with the actual situation of hydraulic shears, and use the means of "asking, watching, listening, touching, and testing" to quickly diagnose the location of the fault and one of the reasons. Methods, namely:
1. "Ask": By asking the operator of the hydraulic shearing machine, what faults have occurred in the hydraulic machine, it is helpful for the repairer to diagnose the fault;
2. "Look": By observing the working conditions of the hydraulic shearing machine, such as pressure gauges, pressure relays, position sensors, etc., it can be diagnosed whether a certain hydraulic component is feasible;
3. "Listen": By listening to the sound of the hydraulic system and components when the hydraulic shearing machine is working, it helps to diagnose whether the components are working properly;
4. "Touch": It is to use sensitive finger touch to check whether the pipelines or components of the hydraulic system have vibrations, shocks, and abnormal oil temperature rise;

5. "Test": It means to operate the actuator of the machine's hydraulic system and determine the location and cause of the failure from its working conditions.

The after-sales maintenance personnel of the scrap steel shearing machine must have certain knowledge and practical experience of hydraulic transmission. By mastering the main parameters of the system, they are familiar with the structure and working principle of each hydraulic component. From the outside to the inside, easy first and then difficult" order, conduct a comprehensive analysis and comparison, and quickly make an accurate diagnosis.
The reasons for general failures can be divided into the following 5 aspects:
1. The sealing element is damaged or impurities make the hydraulic element unable to work normally;
2. The hydraulic components are worn or damaged, such as valve components sealing failure, spring failure, etc.;
3. Improper adjustment of hydraulic components, such as: incorrect adjustment of pressure and flow of oil pump, oil motor, sequence valve, direction valve, unloading valve, and balance valve;
4. The auxiliary mechanism malfunctions, such as: improper adjustment or damage of the limit switch position, damage to the pressure gauge, damage to the pressure relay or misinformation, fuel tank filtration problems, etc.;

5. The control mechanism (electrical) malfunctions, such as: relay malfunction, poor or damaged button contact, incorrect installation of electromagnet, incorrect connection of motor phase wire, etc., which cause hydraulic components to malfunction or program errors.

The NICKBALER scrap steel shearing machine is easy to install, simple to operate, convenient to maintain, and has a small footprint. It is a good equipment to improve labor efficiency and reduce transportation costs. https://www.nkbaler.net

There are many kinds of failures in the hydraulic system of the scrap shears. One failure may be caused by many factors, which brings great difficulties to the diagnosis and analysis. Therefore, in the repair of the hydraulic system of the scrap shears, it is necessary to Use some practical methods with strong operability to diagnose.
Fault diagnosis method of scrap steel shearing machine:
1. Exchange method
When only a certain circuit or a certain function is lost in the hydraulic system, replace and install the same components on the hydraulic press of the same type, structure and principle in the same position. If the fault persists, it means that the component is not If the problem does not exist, use the same method to check other components. If the fault does not exist, it means that the component is faulty.
The advantage of this method is that even if the repairer has a low technical level, it can be used to make an accurate diagnosis of the fault of the hydraulic machine.
2. Auxiliary method
With the help of simple auxiliary parts, it can diagnose whether the hydraulic components of the hydraulic shearing machine are malfunctioning.
1) Artificial reversing method, using the ejector rod to reversal valve components, can diagnose whether the reversing valve is stuck, the valve core is not in place and other faults.
The auxiliary method avoids excessive disassembly workload, reduces fault diagnosis time, and facilitates rapid diagnosis, especially for larger cylinder seals. This type of fault diagnosis has good practicability.

2) The oil blocking method, such as blocking the oil ports of valve components and cylinder oil ports, can diagnose whether these hydraulic components are leaking or failing.

The machines produced by NICKBALER have the characteristics of many varieties, complete specifications, and strong compatibility, and can be designed and manufactured according to customer requirements. https://www.nkbaler.net

Hydraulic oil is the working medium of the hydraulic system. Whether the hydraulic oil is clean or not will not only affect the service life of hydraulic components and the working performance of the hydraulic system, but also directly affect whether the hydraulic metal shearing machine can work normally.
Therefore, it is very important to prevent oil contamination of hydraulic metal shears.
1. The hydraulic oil of the metal shearing machine should be kept clean before use. The hydraulic oil will be contaminated by the outside world during transportation and storage. The newly purchased hydraulic oil looks very clean, but it is actually very dirty. It must be left for a few days. , After being filtered, it is added to the hydraulic system for use.
2. Keep the hydraulic oil clean during work. The hydraulic oil will be polluted by the environment during work. Therefore, try to prevent the intrusion of air and moisture. In order to completely eliminate the intrusion of water, air and pollutants, seal the oil tank and add air to the vent hole. Filter.
3. The fuel tank should be properly sealed, and air filters should be installed in the atmosphere, and the seals must be reliable. It is forbidden to use non-oil-resistant seals and hoses.

4. Replace the oil regularly. The oil tank must be cleaned once before replacing the new oil. When the system is dirty, it can be cleaned with kerosene. After draining, inject new oil.

The hydraulic cylinder of the hydraulic shearing machine is the power conversion device in the hydraulic system, so it is essential to do a good job in the daily maintenance of the hydraulic cylinder of the hydraulic shearing machine.
Daily maintenance skills of hydraulic cylinders of hydraulic shears:
1. Cleaning:
The pipeline and the fuel tank should be cleaned to prevent falling off oxide scale and other sundries. For cleaning, use lint-free cloth or special paper. The fuel tank should be sealed to prevent contamination.
2. Open the box and change the oil:
After long-term use of hydraulic shears, foreign matter will inevitably enter the hydraulic cylinder, which will increase friction during use. In addition, the hydraulic oil has a certain service life. If the oil is not changed, the hydraulic cylinder will be damaged or corroded. .
3. Inspection of each part:
The oil cylinder of the hydraulic cylinder should also regularly check the leakage of each seal, as well as whether the bolts of the connecting parts are loosened or not, so as to prevent accidents.
4. Temperature:

Control the temperature of the hydraulic system. Excessive oil temperature will reduce the service life of the seal. Long-term high oil temperature will cause permanent deformation of the seal, or even complete failure.
