Angola hydraulic cylinder,loading cylinder manufacturer,loading cylinder(Angola loading cylinder,produced by Hengyu Group)
loading cylinder are widely used in Angola,because of excellent temperature resistance,no transmission clearance,powerful torque.So our company has designed loading cylinder for customers from Angola.
If the piston rod and loading cylinder are stuck or the loading cylinder is blocked, at this time, no matter how to operate, the loading cylinder does not move or has little action. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the loading cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.
The loading 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 loading cylinder should pay attention to: the operation should be as far away from the loading cylinder as possible, to avoid falling objects, knocking, rubbing the loading cylinder coating. When cleaning the loading cylinder, only use soft materials (such as cotton) to wipe, and do not scratch high-hardness materials. Do not use the loading cylinder when the oil temperature exceeds 70 ° C.
The loading cylinder is not the same as the loading cylinder, because the pressure of the pneumatic system is generally within the range of 0.2-1.0Mpa, the loading cylinder can not be used as a high-power power component, but the loading cylinder can be used as a relatively large power component, or the loading cylinder system can be used.
The material, shape and compression of the loading cylinder seal have a great impact on the service life and work efficiency of the loading cylinder. In addition to requiring a reliable seal, it should also have a long service life and less friction loss. At present, there are many seal manufacturers in the country, and it is also crucial to choose high-quality seals with reliable and stable quality.
Hydraulic cylinder cost calculation method
1, Price cost accounting. Hydraulic cylinder price is composed of cost, profit and tax rate. Among them, the cost includes material cost, processing cost, assembly test fee, factory management fee (including the cost of designing drawings, etc., and the salary of management personnel is shared equally), brand promotion fee, utility and electricity equipment depreciation fee and other expenses. Cost of materials, including cylinder composition cylinder, piston rod, front and rear cover, guide, piston, seal, other accessories, etc. 2, Roughly estimate cylinder price = cylinder weight * parameters, parameters comprehensive consideration of various material costs and processing fees. The general market parameter is 20, the smaller and lighter the cylinder, the larger and heavier the cylinder, the smaller the parameter.
When the cylinder is tested, why can't the pressure be maintained with the balance valve?
Because the oil into the oil chamber through the hydraulic lock on the control oil circuit through the other side of the spool, the original valve is designed in this way. It locks the circuit after the oil supply circuit loses pressure, on the contrary, if you keep supplying pressure, it is always in the state of opening the other side of the one-way spool. So this valve can't be used in the test.
