(Pakistan hydraulic gate cylinder,produced by Hengyu Hydraulic Co., Ltd）
hydraulic gate cylinder are widely used in Pakistan，because of long service life，smooth movement，high work efficiency.So our company has designed hydraulic gate cylinder for customers from Pakistan.
The main role of the hydraulic gate cylinder: the hydraulic gate cylinder is an executive element in the hydraulic transmission system, which is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic motor realizes continuous rotary motion, while the hydraulic gate cylinder realizes reciprocating motion. The structure of the hydraulic gate cylinder has three categories: piston hydraulic gate cylinder, plunger hydraulic gate cylinder, swing hydraulic gate cylinder, piston hydraulic gate cylinder and plunger hydraulic gate cylinder to achieve reciprocating linear motion, output speed and thrust, swing hydraulic gate cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the hydraulic gate cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The hydraulic gate cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.
When the hydraulic gate cylinder is in use, ensure that the hydraulic gate cylinder and the surrounding environment should be clean. The tank should be sealed to prevent contamination. Pipelines and fuel tanks should be cleaned to prevent falling off the oxide sheet and other debris. Clean with lint-free cloth or special paper. Twine and binder should not be used as sealing materials. Hydraulic oil according to the design requirements, pay attention to the change of oil temperature and oil pressure. When there is no load, unscrew the exhaust bolt for exhaust.
When the hydraulic gate cylinder needs to be stored for a period of time, please follow the recommended methods: The hydraulic gate cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the hydraulic gate cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil hydraulic gate cylinder should not be in direct contact with water vapor for a long time. The hydraulic gate cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the hydraulic gate cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the hydraulic gate cylinder Before working, the hydraulic gate cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the hydraulic gate cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.
The meaning of the hydraulic gate cylinder model marked by the hydraulic gate cylinder manufacturer: for example, 160/100-1150, its meaning: from a professional point of view, 160 refers to the hydraulic gate cylinder diameter, which is 160mm, and the 100 behind refers to the rod diameter, which is 100mm. The 1150 refers to the hydraulic gate cylinder stroke, which is 1150mm. Therefore, on this point, we should have a correct understanding and can not make mistakes.
Why does the tipping bucket cylinder have a cylinder withdrawal problem?
This problem may have a certain relationship with the operation of the driver, the main reasons are the following two situation analysis: 1, the current domestic loader working device is mostly a six-link mechanism, the six-link mechanism in the bucket to the limit position, lift the boom, the rotating bucket cylinder will appear "cylinder pulling" phenomenon, that is, the piston rod of the rotating bucket cylinder will be pulled out. In this case, in order to protect the cylinder, a pressure overload protection valve with large and small cavities is provided on the multi-way valve rotating bucket link (large chamber 18MPa, small chamber 12MPa). 2, before the cylinder is assembled to the whole machine, the cylinder is not limited, the piston rod of the cylinder can be pulled in place before and after, but when it is installed on the whole machine, in order to avoid the cylinder pulling out, the limit switch is installed according to the regulations.
What are the cylinder manufacturing processes?
Hydraulic cylinder processing process: 1, cylinder: a, material preparation (seamless steel pipe) → inspection (material certificate, etc.) → tempering (outsourcing: Some parts) → car (car round, shelf mouth, boring, flange stop, etc.) → tempered hardness test → welding (welded pipe joint base, flange and other accessories) → boring or honing (rough boring, fine boring, rolling) → car (hole slot or internal and external thread) → fitter (drilling) → inspection → rust prevention storage b, material preparation (forgings) → inspection (material certificate, inspection, etc.) → welding (blank butt welding) → welding inspection → car (rough car) → quality control (outsourcing: some parts) → car (car round, shelf mouth, boring stop, flange stop, etc.)
