Oman hydraulic cylinder,pusher hydraulic cylinder manufacturer,pusher hydraulic cylinder(Oman pusher hydraulic cylinder,produced by Hebei Hengyu company)
pusher hydraulic cylinder are widely used in Oman,because of excellent temperature resistance,no transmission clearance,powerful torque.So our company has designed pusher hydraulic cylinder for customers from Oman.
The difference between the integral pusher hydraulic cylinder and the split pusher hydraulic cylinder: The integral pusher hydraulic cylinder and the split pusher hydraulic cylinder in the pusher hydraulic cylinder are two different pusher hydraulic cylinders, and they are very different. The whole pusher hydraulic cylinder, which is cast in one body, is not prone to problems such as oil leakage; The split pusher hydraulic cylinder is welded twice, so if it is not handled well at the welding, it is prone to problems such as oil leakage and pusher hydraulic cylinder damage. Therefore, it is obvious that the answer to this question is for difference.
The pusher hydraulic cylinder can not be used as grounding electrode to avoid electric damage to the piston rod.
Regular maintenance of the pusher hydraulic cylinder includes: regular tightening, pusher hydraulic cylinder fastening screws and gland screws, pusher hydraulic cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the pusher hydraulic cylinder once a year. Clean regularly, the pusher hydraulic cylinder is cleaned every other year, and the seals are replaced while cleaning.
The cavitation of the pusher hydraulic cylinder has a great influence, and to avoid it, it is necessary to use the hydraulic oil reasonably and ensure the quality of the hydraulic oil. If the anti-foam property of the oil is poor, it is easy to produce foam, resulting in cavitation. Secondly, the change frequency of oil pressure is too fast and too high, which will also directly cause the formation of bubbles and accelerate the rupture rate of bubbles. The test shows that the speed of cavitation will be accelerated in the part with high frequency of pressure change. For example, at the inlet and outlet of the pusher hydraulic cylinder, due to the relatively high frequency of pressure changes, the degree of cavitation is also relatively higher than that of other parts. In addition, overheating of the oil will also increase the probability of cavitation.
How to deal with hydraulic cylinder inner wall rag, local wear serious or corrosion?
It can be reparied if the inner wall of the hydraulic cylinder is frayed, local wear or corrosion. We can use the inner wall cold melting copper technology, it has the following advantages: first, the temperature is low, the operating temperature is less than 180 degrees, and the heat affected zone is small. Second: high hardness is up to Brinell hardness 280, wear resistance and anti-corrosion. Third: the process is mature, some large coal mills have been repaired with this method and the effect is remarkable.
What is the problem that the cylinder stroke is not in place?
1. Mechanical cause: the piston rod bends; If there is a synchronous cylinder, the stroke of the two cylinders may be different. 2. Hydraulic reason: the system back pressure is too large; The actuator load increases while the system pressure decreases. The electric is not sent, the reversing valve is not reset or stuck, the oil is too dirty, there is gas in the system, the external inertia load is too large, and the cylinder stroke is not in place.
