Singapore hydraulic cylinder,extra high pressure cylinder manufacturer,extra high pressure cylinder(Singapore extra high pressure cylinder,produced by Hebei Hengyu company)
extra high pressure cylinder are widely used in Singapore,because of excellent temperature resistance,no transmission clearance,powerful torque.So our company has designed extra high pressure cylinder for customers from Singapore.
If the extra high pressure 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 extra high pressure cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow extra high pressure cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the extra high pressure cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the extra high pressure cylinder includes the leakage caused by excessive wear of the extra high pressure 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 extra high pressure cylinder, and the phenomenon of "pulling the extra high pressure 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 viscosity of the working oil used in the extra high pressure cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.
If it is found that the extra high pressure cylinder lubrication is poor or the extra high pressure cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the extra high pressure cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the extra high pressure cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the extra high pressure cylinder center line. In this way, when the piston works in the extra high pressure cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the extra high pressure cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.
When installing the piston rod, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the extra high pressure cylinder head adn the earring (or the middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent the phenomenon of rigid interference and causing unnecessary damage.
Hydraulic system schematic diagram, pipeline identification S and L, respectively corresponding nominal diameters? 16S is equivalent to DN12 high-pressure cylinder, and 15L means what?
16S refers to the high pressure series, outer diameter 16x2 steel pipe, the corresponding sleeve nut is M24X1.515L is the low pressure series, the outer diameter of 15x1.5 steel pipe, the corresponding sleeve nut is M22X1.5.
What is the difference between gas-hydraulic pressurized cylinder, pneumatic cylinder and oil cylinder?
The cylinder block is small and the force is large, constant speed and variable speed can be used (easy to change), the adjustment of the output is also convenient, and the freedom of transmission is high. However, maintenance costs and installation costs are high, and there is the trouble of mild oil pollution. Easy cylinder control, low price, easy access to energy. But the force is small, and can not achieve the effect of stable speed. The gas-liquid pressurized cylinder has the advantages of both of the above: environmental protection and energy saving, easy control, and simple adjustment. However, the output of the trip has certain restrictions, more suitable for short trips, large output, but also environmental protection and energy saving and low configuration of the occasion.
