Uganda hydraulic cylinder,swager cylinder manufacturer,swager cylinder
(Uganda swager cylinder,produced by Hebei Hengyu company）
swager cylinder are widely used in Uganda，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed swager cylinder for customers from Uganda.
swager cylinder spool stuck or valve hole blocked How to solve: When the flow valve or direction valve spool stuck or valve hole blocked, the swager cylinder prone to misoperation or action failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium.
If the swager cylinder operation failure, you can start from these aspects to troubleshoot: (1) the hydraulic system control pressure is too low. The throttling resistance in the control line may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is disturbed. At this time, the control pressure source should be checked to ensure that the pressure is adjusted to the specified value of the system; (2) Air enters the hydraulic system. Mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced. (3) The initial action of the swager cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow swager cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the swager cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the swager cylinder includes the leakage caused by excessive wear of the swager cylinder block seal, the piston rod and the seal cover seal and the piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time. The main cause of excessive piston seal wear is improper adjustment of the speed control valve, resulting in excessive back pressure and improper seal installation or hydraulic oil contamination. The second is that foreign bodies enter the assembly and the quality of sealing materials is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and swager cylinder, and the phenomenon of "pulling the swager cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operations should be done according to the installation instructions.
The daily inspection of the swager cylinder includes: checking the connection of the swager cylinder and the pipe joint for leaks. Check the swager cylinder rod for leaks. Check the swager cylinder connection for leaks. When the swager cylinder moves, the work is normal and smooth. Whether the swager cylinder has internal leakage.
In use, the swager cylinder should try to avoid the friction iron powder or iron filings formed by buffering the plunger. When the matching gap of the buffer device is small and the transverse load on the piston rod is large, the sintering phenomenon may be caused. These friction iron powder or the metal fragments that have fallen off as a result of sintering will remain in the swager cylinder.
What is a hydraulic cylinder assembly?
Assembly, which means aggregate. A series of parts or products, formed to achieve a specific function of the whole, the general term for this system is assembly. The hydraulic cylinder assembly is not a single hydraulic cylinder part, which can be used by connecting the hydraulic hose.
How do hydraulic equipment and hydraulic cylinders maintain a certain pressure after pressing to a certain position?
There are several methods. 1. You can use a constant pressure variable pump to adjust the control pressure of the pump to the pressure required by the cylinder, so that when the cylinder is in place, the pump uses the minimum flow rate to maintain the pressure, and the system is more energy saving. 2. If the pressure is maintained for a short time, a hydraulic control check valve can be added to the oil inlet end of the cylinder to close the cylinder and maintain the pressure. If the volume of the cylinder is large, an accumulator can be added between the valve and the cylinder to maintain pressure for 10-30 minutes. 3. You can add a small flow pump, the large pump after unloading, the small pump has been running, specifically for maintaining pressure.
