Malaysia hydraulic cylinder,plunger type cylinder manufacturer,plunger type cylinder(Malaysia plunger type cylinder,produced by Hengyu Group)
plunger type cylinder are widely used in Malaysia,because of no transmission clearance,powerful torque,clever hydraulic energy conversion.So our company has designed plunger type cylinder for customers from Malaysia.
The definition of the minimum stable speed refers to the minimum movement speed of the plunger type cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the plunger type cylinder that undertakes different work has different requirements for the minimum stable speed.
plunger type cylinder hydraulic oil selection: The recommended working oil viscosity of the plunger type cylinder is 10 ~ 110cSt (1.8 ~ 15E), ISO VG46 hydraulic oil. The normal working oil temperature is 10 ~ 70℃, and the ambient temperature is in the range of -20 ~ 80℃. When the ambient temperature and service temperature are low, the hydraulic oil with lower viscosity can be selected.
The machining accuracy of the plunger type cylinder depends on the level of equipment, production technology and testing means. plunger type cylinder processing methods are commonly used in two ways, one is rough boring - fine boring - rolling, generally with 45# seamless steel pipe, this method of processing quality is good, but the cost is high. Another method is to use 20# cold-drawn seamless steel pipe, and then honing, the cost is lower. The piston rod must be adjusted and straightened before processing, and the coating thickness of the piston rod is generally not less than 0.03mm. The piston must be machined in strict accordance with the groove size and tolerance requirements given in the seal manual.
When the plunger type cylinder is in use, measures should be added to prevent the intrusion of pollutants. Effective measures should be taken to control the intrusion of pollutants, such as installing high-efficiency air filters in the tank breathing holes, new oil must be filtered, etc., but also must improve the anti-pollution ability of the plunger type cylinder itself. In the seriously polluted environment, it is more important to pay attention to, such as the underground oil plunger type cylinder should use fluorine rubber (FRM) and nitrile rubber (NBR) dust ring, and the ground mechanical plunger type cylinder should use nitrile rubber dust ring; The filter device is added to the oil inlet of the plunger type cylinder of the dump truck, construction machinery, work platform and other equipment, and in order to reduce the oil inlet resistance, the flow area should be increased as much as possible, which can effectively reduce the particle pollution from the system.
Need to buy a hydraulic cylinder, now only know that the pressure needs to be between 20t and 50t. Two-way travel, how to determine the type of cylinder?
Important parameters of the cylinder: cylinder diameter, stroke, use pressure. First, the system pressure must be determined according to the precision of the operation of the application equipment, and the cylinder diameter can be determined by the force and system pressure. Then, according to how the equipment and the cylinder are installed and connected, determine the installation method of the cylinder and then determine the specific installation size, the size of the oil port, whether the buffer is needed and other details.
Does the sealing string of the upper and lower chamber of the hydraulic cylinder fall by itself?
It is possible, the probability accounts for 85% (depending on the weight), the weight is less than the system resistance, may not fall, the weight is greater than the system resistance, will not necessarily fall, so often check the equipment, safety first, find the problem in time to solve, the cylinder is not very expensive parts, maintenance does not cost much money, However, accidents caused by cylinder failure will lose several times the cost.
