Characteristics of hollow hydraulic wrench and precautions for use

　　As we all know, hydraulic wrenches are mainly divided into hollow hydraulic wrenches and driving hydraulic wrenches. The driving hydraulic wrench has a square drive shaft, which needs to be equipped with a driving sleeve, while the hollow hydraulic wrench working head is a hollow hexagon, which can be directly sleeved on the nut. Today, Zhonghong Precision will talk about the characteristics of the hollow hydraulic wrench and the precautions for use.

　　1. Characteristics and application of hollow hydraulic wrench:

　　1. Thin design, made of high-toughness aluminum-titanium alloy material, fully enclosed overall body structure, no exposed parts, safe and good working characteristics; it can prevent dust and dirt from entering, and maintenance related parts will not be got damage. This component is highly integrated and has high stability.

　　2. Plug-in structure, one power head can be used with a variety of working heads, which is convenient to replace the working head; rotatable hose joints are suitable for tight places and easy to operate.

　　3. The repeated precision of the torque can reach plus or minus 3%, the compressive strength of the wrench and its design process are sufficient; the overall lengthening of the recoil arm, no space limitation, durable and reliable.

　　4. Without a sleeve, it directly acts on the nut, and the torque is more accurate.

　　5. The design of the stop pawl can overcome the reversal of the ratchet and improve the work efficiency and torque accuracy.

　　6. Jinghong hydraulic wrench has been using imported core components so far, only to improve the service life of hydraulic wrench, making it safer and more durable.

　　7. Hollow hydraulic wrench has a wide range of applications: hollow hydraulic wrench is thinner and thinner, especially in sites with small indoor space; suitable for power engineering (nuclear power plants, wind power generation, hydropower engineering, thermal power plants), ships, metallurgical industry , transportation, concrete, engineering construction, airlines, machinery, petrochemical and other industries.

　　Second, the use of hollow hydraulic wrench matters needing attention:

　　1. Professionals are required to operate the hydraulic wrench. It is best not to operate the hydraulic wrench without training. Novices should operate under the guidance, read the manual carefully before operation, and master the operation method. Only those who have been trained to the standard can operate the wrench.

　　2. Select the appropriate hydraulic oil. The quality of the hydraulic oil has a great impact on the equipment. If the hydraulic oil is of poor quality or has been polluted, the performance and efficiency of the hydraulic wrench will be affected. You should choose anti-wear hydraulic Oil, this kind of hydraulic oil has outstanding advantages and can ensure the stability of the hydraulic system.

　　3. The oil temperature of the system should be well controlled, and the oil temperature should be between 25°C and 45°C. Below or above this range will have a negative impact on the system. Once a fault occurs, it will affect production.

　　4. Always check the equipment condition, so that any problems can be found at the first time. Especially in the hydraulic system, it may have problems such as unstable oil pressure, system vibration, and oil temperature rising too fast. These phenomena are relatively common. It is necessary to analyze the reasons in time, and then choose the appropriate method to eliminate the fault, so as to avoid the occurrence of the accident.

　　5. The operator should not disassemble the hydraulic components casually. If there is a fault, they should also find a professional maintenance personnel to deal with it. If you do not understand the work in this area and force maintenance, it is not good for the hydraulic system. If the problem is exacerbated by improper maintenance, it will add unnecessary maintenance costs to the business.
