What is the principle and structure of the bollard ?
The hydraulic rising bollard is formed by a vane pump to form a certain pressure, and enters the lower end of the hydraulic cylinder through the oil filter, explosion-proof electromagnetic directional valve, throttle valve, hydraulic control check valve, and balance valve to make the piston of the hydraulic cylinder move upward. Lift the weight, the oil return from the upper end of the cylinder is returned to the oil tank through the flameproof electromagnetic reversing valve, and its rated pressure is adjusted by the overflow valve, and the reading value of the pressure gauge is observed through the pressure gauge.
The piston of the hydraulic cylinder moves downward (that is, the weight drops). The hydraulic oil enters the upper end of the cylinder through the explosion-proof electromagnetic reversing valve, and the oil return from the lower end of the cylinder returns to the tank through the balance valve, hydraulic control check valve, throttle valve, and explosion-proof electromagnetic reversing valve. In order to make the heavy objects fall smoothly and the brakes are safe and reliable, a balance valve is installed on the oil return line to balance the circuit and maintain the pressure so that the descending speed is not changed by the weight. The throttle valve adjusts the flow rate and controls the lifting speed. In order to make the brake safe and reliable, and prevent accidents, a hydraulically controlled one-way valve, that is, hydraulic lock, is added to ensure that the hydraulic pipeline can be safely self-locked when the hydraulic pipeline bursts accidentally.
1. All stainless steel manufacturing: the products are all made of stainless steel raw materials, with longer life and more durable.
2. Electrophoresis anti-corrosion treatment: all buried equipment adopts anti-corrosion treatment to make it resistant to acid and alkali corrosion.
3. Precision machining of CNC machine tools: All components are processed by CNC machine precision machining centers to make it run more closely and smoothly.
4. Hydraulic integrated type: on-site installation and debugging are convenient, and it is not easy to change the factory state during transportation and installation. The product lifting speed and time uniformity are better than other driving types of rising bollards, and the composition method of the rising bollards can be flexibly configured.
5. Submersible power unit: It can work normally in the water, and it is easy to be affected by rain and snow without installation on the top.
6. No oil circuit design: The power unit and the lifting system are integrated design, without oil circuit tubing, to avoid oil circuit tubing from corrosion, oil leakage at the interface and oil leakage from the quality of the tubing.
7. Maintenance-free design: The hydraulic rising bollard does not require special maintenance during use, and there is no complicated operation, and it can be completely disassembled.
8. Electroplating gold design: Electroplating gold can effectively improve the corrosion resistance of stainless steel, and prevent stainless steel from fading after a period of use.
9. The panel is made of stainless steel: the floor panel is made of stainless steel, which is more sturdy and improves the anti-collision performance.
10. Dome light warning and lighting: sealed LED dome light warning light can greatly improve the warning effect and realize the brightening effect.
