(Burma extra high pressure cylinder,produced by Hebei Hengyu company）

extra high pressure cylinder are widely used in Burma，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed extra high pressure cylinder for customers from Burma.

Introduction to extra high pressure cylinder:

The extra high pressure cylinder should be avoided for a long time without use, if it is indeed idle for a long time for some reason, it should also be regularly turned on for empty operation, so that its parts can be fully lubricated, so as to avoid rust on the working surface and affect the normal work in the future. (If it cannot be turned on and run, a small amount of lubricating oil can be applied on its outer surface for protection) ' The use of the extra high pressure cylinder should pay attention to: the operation should be as far away from the extra high pressure cylinder as possible, to avoid falling objects, knocking, rubbing the extra high pressure cylinder coating. When cleaning the extra high pressure cylinder, only use soft materials (such as cotton) to wipe, and do not scratch high-hardness materials. Do not use the extra high pressure cylinder when the oil temperature exceeds 70 ° C.

When the control pressure of the hydraulic system is too low, the extra high pressure cylinder will appear wrong or no action, because the throttle resistance in the control pipeline may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is interfered with. At this time, check the control pressure source to ensure that the pressure is adjusted to the specified value of the system.

When the hydraulic oil is not pumped into the extra high pressure cylinder, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the extra high pressure cylinder to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.

How the cavitation of the extra high pressure cylinder is formed: With the gradual rise of pressure, the gas in the oil will become bubbles, when the pressure rises to a certain limit value, these bubbles will break under the action of high pressure, so that the high temperature and high pressure gas will quickly act on the surface of the parts, resulting in cavitation of the extra high pressure cylinder, resulting in corrosive damage to the parts.

Answers to some questions about extra high pressure cylinder:

What welding rod is used for hydraulic cylinder welding?
There are several reasons for bad welding of hydraulic cylinder: 1. There is hydraulic oil on the welding surface, wipe it with a rag, there will be bubbles in the welding process, and it will not last for a few days. You have to remove it, drain it, wash it off with gasoline and try again. 2. Open the groove before welding, it is not deep enough to use the Angle grinding machine, and can not find the accurate crack position. 3. The material of the cylinder itself is not clear, the welding performance of more than 35 steel is not good, in the factory welding needs to preheat, the welding rod should also be dried and insulated, there is no such condition on the site.

Where's the hydraulic cylinder bleed valve?
There is a vent hole at the top of the cylinder next to the intake pipe. Generally, it can be used, and the air in the cylinder can be naturally drained after several moves.
