Thailand hydraulic cylinder,double acting cylinder manufacturer,double acting cylinder(Thailand double acting cylinder,produced by Hebei Hengyu company)
double acting cylinder are widely used in Thailand,because of smooth movement,no need for deceleration device,long service life.So our company has designed double acting cylinder for customers from Thailand.
Causes and countermeasures of oil double acting cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the double acting cylinder will lead to premature wear of the piston seal, replace the piston seal; If the double acting cylinder is visibly scarred, the double acting cylinder must be replaced. It can be pressurized at one end of the double acting cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most double acting cylinder piston drift may not come from the double acting cylinder, the above method to determine the double acting cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.
When the double acting cylinder is disassembled due to oil leakage and other faults, the position of the piston should be moved to any end position of the double acting cylinder by applying liquid pressure. Improper tapping and sudden drop should be avoided during disassembly.
double acting cylinder buffer valve inspection and maintenance: For the valve buffer double acting cylinder, the focus should be on checking the wear of the buffer valve spool and seat. Once it is found that the amount of wear increases and the seal fails, it should be replaced. It can also be repaired by using abrasive spool and seat matching grinding method.
The double acting cylinder body is commonly made of No. 20, 35, 45 seamless steel pipe, and the steel pipe is honed or rolled to achieve the roughness requirement within 0.4μm. The low pressure double acting cylinder can use 20 steel pipe, and the high pressure double acting cylinder can use 45 steel pipe.
In a hydraulic system, a hydraulic pump has many hydraulic cylinders and hydraulic motors, and these executive components do not coordinate their actions with each other.
A load-sensitive variable pump can be used if these components sometimes need to work simultaneously and the power required is large. The required flow is distributed by the multi-way reversing valve, and the required flow and pressure changes are automatically adjusted by the hydraulic pump. Pressure reducing valves can be used for particularly low pressure circuits. Because you execute more components, the use of quantitative pump will cause a waste of energy, the system heat is large, not suitable.
How does the cylinder work?
Hydraulic transmission principle: oil as the working medium, through the change of the sealing volume to transfer movement, through the internal pressure of the oil to transfer power. 1. The power part - converts the mechanical energy of the prime mover into the pressure energy of the oil (hydraulic energy). For example: hydraulic pump. 2, the executive part - the hydraulic pump input oil pressure energy into the mechanical energy to drive the working mechanism. For example: hydraulic cylinder, hydraulic motor. 3, the control part - used to control and adjust the oil pressure, flow and flow direction. For example: pressure control valve, flow control valve and direction control valve. 4, the auxiliary part - the first three parts are connected together to form a system, which plays the role of oil storage, filtration, measurement and sealing.
