(Indonesia trailer hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）
trailer hydraulic cylinder are widely used in Indonesia，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed trailer hydraulic cylinder for customers from Indonesia.
In the process of using the trailer hydraulic cylinder, sometimes such a problem will occur, the trailer hydraulic cylinder can not act immediately after the instruction of the trailer hydraulic cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil trailer hydraulic cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.
When using the trailer hydraulic cylinder product, be sure to operate safely in accordance with the specification documents provided by the manufacturer, and pay attention to protecting the trailer hydraulic cylinder block. If the trailer hydraulic cylinder block is damaged, it will cause adverse consequences: ① The material debris extruded from the scratch groove will be embedded in the seal, which may cause new scratch area marks while damaging the working parts of the seal during operation. ② Deterioration of the surface roughness of the inner wall of the trailer hydraulic cylinder, increase friction, easy to produce crawling phenomenon. ③ Increase the internal leakage of the trailer hydraulic cylinder, so that the working efficiency of the trailer hydraulic cylinder is reduced.
When the trailer hydraulic cylinder needs to be stored for a period of time, please follow the recommended methods: The trailer hydraulic cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the trailer hydraulic 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 trailer hydraulic cylinder should not be in direct contact with water vapor for a long time. The trailer hydraulic cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the trailer hydraulic 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 trailer hydraulic cylinder Before working, the trailer hydraulic cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the trailer hydraulic cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.
Protection of the trailer hydraulic cylinder surface: During the dismantling process, safety protection should be carried out on the trailer hydraulic cylinder to prevent objects from falling and welding slag from falling to the surface, causing damage to the trailer hydraulic cylinder surface. In the process of propulsion, the damaged pipe segments should be prevented from falling and smashing, and the slurry remaining on the surface of the trailer hydraulic cylinder should be cleaned up in time.
Why manual forklift oil cylinder can not lift up?
Manual hydraulic forklift truck often can not be pressed up, there are several reasons: for manual hydraulic truck: 1) There is no hydraulic oil 2) the purity of the oil is not enough 3) the adjusting bolt is too close or the adjusting screw is too tight, so that the valve is always open, 4) there is an air in the hydraulic cylinder. Method: 1) Refueling 2) Oil change 3) air discharge. For manual hydraulic stacker, also called manual lift car 1) Less than the amount of oil 2) impurities in the hydraulic oil, so that the check valve can not be closed. Method 1) Add enough hydraulic oil 2) Remove the cylinder, screw off the bottom plate, remove the impurities in the bottom plate.
What are the four cylinders of the truck crane?
The four cylinders of the truck crane generally refer to the telescopic cylinder of the boom (to adjust the length of the boom), the variable amplitude cylinder of the boom (to adjust the elevation Angle of the boom), the horizontal telescopic cylinder of the support leg and the vertical cylinder of the support leg.
