How to prolong the service life of the hydraulic wrench
1. operation personnel must be carefully read and understand the operation manual, the hydraulic
torque wrench installation ,commissioning, testing machine, operation, Maintenance and maintenance to
have a thorough understanding, and after the operation of training, through the assessment,
it can be operated.
2. the quality and cleanliness of the hydraulic oil and the working viscosity determine the reliability
of the hydraulic system of the hydraulic torque wrench.Efficiency, life and economy
of hydraulic torque wrench. Therefore, we must use the anti wear hydraulic oil, the density of
the hydraulic oil is required.0.884G/CM2, the flash point
of 255 DEG C, flow point of -9 Deg. C, the viscosity of 68CM2/S (40 C), 8.8CM2/ (100 DEG C),
viscosity index Number 102.The hydraulic oil can make the stability of hydraulic system of
hydraulic torque wrench,reduce the influence of temperature on viscosity,
3. Enhance the wear resistance and corrosion resistance of the system, the hydraulic torque wrench
cylinder sealing work is good.The temperature control system: 3 good system allows the minimum
oil temperature is 25 DEG C. The optimum operating temperature is 35 -45, which is more than
45 for the system is unfavorable. If more than the required value of the system to check, timely investigation.
4. To check the problem: when the hydraulic system failure, it is time to analyze the reasons,
troubleshooting, do not allow hydraulic Torque wrench work, cause big accidents.
5. Regular inspection and fastening pipe joints to prevent loosening of oil leakage.
6. Do not change the hydraulic components, if the hydraulic wrench, please contact the professional
personnel for maintenance.
Hydraulic wrench maintenance
1. The hydraulic wrench in the handling and use of the process is strictlyforbidden to touch, hammer,
to prevent damage.
2. Working fluid for hydraulic oil, alcohol, water and other media is strictly prohibited as working fluid,
and should keep working fluid clean and pure.
3. Hydraulic torque wrenches should be kept clean, especially the import and export of oil sludge may
not have dirt.
4. Hydraulic wrench for longterm storage, should be coated withVaseline as antirust processing industry, and should be stored in a dry container,Indoor temperature.
The hydraulic power system maintenance of hydraulic wrench
1. The hydraulic system connecting tubing connector apart should be screwed on the thread plug,
to prevent contamination of oil sludge.
2. High pressure hose for long-term use, aging will reduce the intensity,
should pay attention to regular replacement.
3. system should be used in non paint surface coated with a layer of petroleum jelly to prevent rust.
Use safety considerations
1. The use of the first carefully read the hydraulic torque wrench instructions and hydraulic system,
the correct installation, use of hydraulic wrench. According to the situation of the right to choose the working pressure,
the pressure is strictly prohibited, In order to avoid accidental injury.
2. The use of oil pressure and elongation calculation should be accurate, to ensure that
no mistake, if there are concerns, please contact the supplier.
3. The pre tightening the strict control of oil cylinder pressure, the use of oil pressure
should be less than the rated pressure, is strictly prohibited. Hydraulic wrenchShould
be coupled with reliable, the oil port should be no leakage of the oil can work.
4. The use of pressure at any time to pay attention to the stress of the work of the case,
if there is abnormal should be treated and then used.
5. The hydraulic torque wrench to reach the end of the trip, should stop the pressure,
the valve handle to change back to pressure.
6. The use of hydraulic wrench should be strictly checked, there is no damage to the strength
of the damage.
The maintenance of the hydraulic pump station
1. Daily inspection of the products of the fasteners, such as: whether the loose screws, etc.,
check the installation of pipeline interface, etc..
2. Check oil seal. Need to regularly clean the oil seal, to prevent the impact of the use of
mechanical life.
3. Recommended for he first time after 500 hours, the replacement of hydraulic oil, hydraulic oil
replacement maximum period of 2000 hours,with the maximum replacement period of air
filter for 500 hours.
4. To optimize the use of hydraulic components, please replace the hydraulic oil and filter.
Hydraulic pollution is the main rea son for the damage of hydraulic components.
Maintenance and maintenance, please keep hydraulic oil clean.
5. Daily use should check the hydraulic oil level whether meet the requirements, and check the hydraulic
oil water content and the presence of abnormal odor. Water hydraulic oil, the oil is cloudy or milky,
or at the bottom of the oil tank water precipitation. When there is a stench, the oil is too high.
When this happens, replace the hydraulic oil immediately, and find out the cause of the problem
and solve the problem. Daily attention to check whether there is leakage of vehicles.
6. Trial operation and operation of the axial piston pump components must be filled with
hydraulic oil side by side net air.
After stopping after a long time, the need for oil and exhaust operation, because the system may
drain through the hydraulic pipeline.
7. Pollution of the hydraulic components of a fatal damage, to ensure the maintenance and repair of the
work environment clean. Before starting the maintenance or repair, please clean the pump
or motor thoroughly.
8. Replace the system's hydraulic oil and filter periodically according to the recommended standard,
ensure the system runs efficiently and safely, and replace the spare parts regularly.
Composition and the classification of hydraulic pump station
1. Hydraulic pump station has the following five basic parts: the hydraulic pump module,
the fuel tank module, the temperature control module, the filter module and the accumulator.
2. According to different standards, can have different classification
of hydraulic pump station:
Depending on the placement of hydraulic pump unit can be divided into superimposed type
hydraulic pump station, non superimposed type hydraulic pump station, cabinet type hydraulic pumping
station and portable hydraulic pump station;
According to the power source of the hydraulic pump station, can be divided into electric type, motor type and manual type;
According to the hydraulic pump output pressure to the sub,can be divided into ultra high pressure,
high pressure, medium pressure and low pressure.
