Failure Analysis and Treatment of Outer Cladding
Hose not adapted to ambient temperature Due to the unsuitable selection of hose, the rubber hose in the low-temperature environment when working under the operation or bending Cracks appear when operating or bending in low temperature environment; rubber aging phenomenon appears when working in high temperature environment. Aging phenomenon. Treatment: the machine works in cold […]
Analysis and Treatment of Hydraulic Hose Failure
Hydraulic hose is the key connection of hydraulic system, in the process of using In the process of use, there are often problems such as leakage, cracking, buckling and loosening, which wastes oil, pollutes the environment, affects the appearance of the machine and reduces the competitiveness of the machine. pollute the environment, affect the appearance […]
Installation & Cleaning of Hydraulic Hoses
The installation and cleaning of hydraulic hoses requires professional operation, improper operation will reduce the service life of the hoses, please be careful. Installation By the construction machinery design of the structure of space and other factors, the requirements of the hose in the maximum pressure conditions to work continuously and stably need to have […]
How to Match Hydraulic Hoses
When matching high-pressure hose, the number of steel wire layers, joint shape and size should be reasonable. If the inner diameter of the hydraulic hose is too small, it will affect the performance of the whole hydraulic system and increase the flow rate of hydraulic oil in the hose, resulting in excessive pressure difference and […]
The compatibility of hydraulic oil with the hose inner tube.
The hydraulic oil and the rubber layer inside the hose must be compatible, and the compatibility of rubber is usually evaluated by the index of volume change and hardness change. As phosphate ester-based and petroleum-based hydraulic fluid chemical properties are very different many hoses are suitable for one or more hydraulic fluids, but not for […]
Considerations for the Working Environment of Hydraulic Hoses
Construction machinery construction conditions are harsh, the ambient temperature is sometimes high and sometimes low, which is increasingly high requirements for the performance indicators of hydraulic hose weather resistance, oil resistance. Impulse & Pressure Hydraulic system high impulse, high pressure harsh conditions of use, easy to cause the hose pulse performance reduced, hydraulic oil pressure […]
Introduction and Structure of Hydraulic Hoses
Introduction of Hydraulic hose As the “bloodline” of hydraulic system of construction machinery, hydraulic hoses are mainly used for transporting hydraulic oil, absorbing hydraulic shock, having good resistance to bending and fatigue, and at the same time, the hoses have to bear frequent pulse pressure changes in the system. Due to the variety and structure […]
