(Brazil flanged hydraulic cylinder,produced by Hengyu Group）
flanged hydraulic cylinder are widely used in Brazil，because of excellent fatigue and impact resistance，smooth movement，high work efficiency.So our company has designed flanged hydraulic cylinder for customers from Brazil.
The flanged hydraulic cylinder can not be used as grounding electrode to avoid electric damage to the piston rod.
flanged hydraulic cylinder and hydraulic station selection: Select the type and structure of the flanged hydraulic cylinder according to the operation requirements of the main engine. According to the external load force borne by the flanged hydraulic cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the flanged hydraulic cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the flanged hydraulic cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the flanged hydraulic cylinder, the diameter of the piston and the piston rod.
After chrome plating of the piston rod of the flanged hydraulic cylinder, the surface flatness is not fully treated: After chrome plating of the piston rod surface, the method of post-plating polishing should be changed to post-plating polishing. Although it is necessary to increase the thickness of the coating before grinding (generally increased by about 0.02 in the diameter direction), it can remove chrome plating defects well, and test the binding force of the coating. In addition, due to the micro-roughness of the grinding surface, the trough can store lubricating oil, which can improve the wear resistance and extend the service life.
The flanged hydraulic cylinder should be used correctly and maintained regularly. The flanged hydraulic cylinder should be deflated before use, the buffer regulating valve should be adjusted to a reasonable position, the cleanliness of the oil should be checked regularly, the dust on the flanged hydraulic cylinder should be cleaned regularly, and attention should be paid to waterproof and fireproof.
Why is the cylinder not in place when the concrete pump truck changes the piston?
When the concrete pump truck changes the piston, the cylinder is not in place mainly because the transfer oil connecting the two cylinders is not completely drained. Sany and Zhonglian have a piston return switch, which can be used to back the piston to the cleaning tank. The elephant is equipped with a stop valve at the bottom of the oil cylinder, usually in the closed state, when opened, the piston can be returned to the cleaning tank, remember to close the valve after the piston is updated.
Why hydraulic cylinder load can not rise?
The hydraulic cylinder does not top up indicates that the pressure of the working chamber of the hydraulic cylinder is insufficient, and the following circumstances can lead to insufficient pressure: 1) The relief valve of the hydraulic system cannot establish pressure, elimination method: check whether the pressure setting screw of the relief valve is screwed to the appropriate position. If it is an electromagnetic relief valve, please check the power-on condition. 2) The hydraulic system pipeline is connected incorrectly, when P and T are connected, this must be checked and excluded; 3) Excessive leakage in the hydraulic cylinder, resulting in (only for double-acting cylinders); 3) No hydraulic oil into the working chamber of the hydraulic cylinder, elimination method: first disassemble the hydraulic pipe connecting the reversing valve and the hydraulic cylinder, and then control the reversing valve, and observe whether there is hydraulic oil flowing out of the reversing valve.
