Electric hydraulic jack is a kind of using hydraulic oil medium.
It is an important part of hydraulic drive and the transfer of energy working medium.
In addition to providing energy, but also can lubricate moving parts and protect the metal from rusting.
The quality of the hydraulic oil and its various performance will directly affect the work of the hydraulic system.
Magnet manufacturer according to the requirement of the hydraulic system use oil, there are the following: 1.
Suitable viscosity and good viscosity-temperature properties of commonly used in the hydraulic oil viscosity range as: hydraulic system parameter = 11.
5 x 10 -
10 square meters/SEC (
2 ~ 5°
Hydraulic transmission machinery lubrication performance, in addition to hydraulic components, some other relative sliding parts also should use the hydraulic oil for lubrication, therefore, the hydraulic oil should have good lubrication performance.
In order to improve the lubrication performance of the hydraulic oil, add additive in lubricating oil in order to improve the lubrication performance.
Good chemical stability to heat, oxidation, hydrolysis and compatibility have good stability.
The relative motion of the hydraulic equipment and parts with good lubricity, 5.
Have rust and corrosion of metal materials.
Specific heat capacity, thermal conductivity, small thermal expansion coefficient of 7.
Bubble sex good, good demulsibility 8 oil purity, less impurities, the quality of 9.
Low pour point and freezing point, flash point,
Can make the oil level of oil vapor combustion flame, but the temperature of the oil itself does not burn)
And high flash point.
In addition, the magnet manufacturer for non-toxic, low oil prices according to different situations.
We want to talk to you about the proportion of the content of the electromagnet, such as those that cause the size of the electromagnet what is the cause of the fault, we will be more elaborate.
Because the plug socket components, workhorse, electromagnet poor contact, and welding, the proportion of electromagnet doesn't work.
At this moment, watt-hour meter can test.
If the resistance is not restricted, can again the welding wire, repair socket, plug.
Aging of the coil component failure has a coil, coil burned, internal break line, coil winding and excessive.
Coil temperature rise more than the output of the assembly and proportional electromagnet force is not enough.
The rest will be made proportional electromagnetic valve does not work.
If the coil is too high, check whether the current is too large, the coil is painted enamel, and whether the valve is caused by the death of dirt card.
Find out the reason and eliminate it.
Under the condition of the bolt and burns, the coil should be replaced.
Magnet manufacturer introduces the armature component failure is mainly due to the armature in the process of using friction pair of wear, lead to the increase of the valve hysteresis.
In addition, the push rod and armature of different heart also will cause the increase of magnetic hysteresis loop, it must be eliminated.
In welding failure or the use of proportional valve pressure pulse, guide sleeve welding section of disconnection, proportional electromagnetic valve is missing.
In use process, the impact pressure and permeability and armature under the wear of friction pair, the force hysteresis in the proportional valve increase.
Proportional amplifier has fault, lead to the proportion of electromagnet doesn't work.
At this point, the amplifier should check all kinds of components and calibration amplifier circuit malfunction.
Ratio between the amplifier and the electromagnet line disconnect or amplifier terminal terminal has been removed, the proportional electromagnet doesn't work.
A broken line should be replaced at this time, in order to firmly to reconnect.
