The pressure system of the electric jack set is complicated. Cavitation on the inner wall, piston or piston rod surface of the electric jack cylinder is caused by a variety of reasons, and it is also a sequelae of irregular use of the schedule. Then analyze today, those improper methods will cause the existence of this problem. It also helps us choose products and use products. This method also brings us a reference to the use of Speciality Hydraulic Bottle Jack.
(1) The hydraulic system's own structure
If the pipelines, control valves and other components of the hydraulic system have too narrow passages and too many elbows, the temperature of the hydraulic oil of the hydraulic jack will increase, and the impact force will increase. It is easy to generate bubbles in the hydraulic oil of the hydraulic jack and cause the air of the hydraulic jack. eclipse.
(2) Material of hydraulic electric jack parts
If the material of the hydraulic jack has good strength, toughness and corrosion resistance, its anti-cavitation ability is good; otherwise, cavitation is prone to occur. In addition, the uniformity of the material structure has a greater impact on cavitation. The more uneven the material structure, the more likely it is to produce cavitation where the strength is weak and where the corrosion resistance is low.
(1) Hydraulic oil quality
The quality of hydraulic oil is an important factor in whether the electric jack produces cavitation. Hydraulic oil inevitably impacts with valves and pipelines during work. If the hydraulic oil has poor foam resistance, it is easy to produce foam, which will cause cavitation in parts such as hydraulic jacks. If the frequency of hydraulic oil pressure changes is too fast or too high, it will also promote the formation of bubbles and accelerate the bursting speed of bubbles. For example, at the inlet and return ports of hydraulic jacks, the degree of cavitation is relatively higher than other parts due to the relatively high frequency of pressure change.Hydraulic oil is also very important for Speciality Hydraulic Bottle Jack. s.
(2) Manufacturing and maintenance
The influence of the assembly or repair quality of electric jacks on its cavitation cannot be underestimated. If the hydraulic system is not fully vented during assembly or maintenance, there will be gas in the system. Under the action of high temperature and high pressure, the hydraulic jack will produce cavitation.
