The approved load capacity of a railway wagon is 60~70 tons, and the overload tonnage of this truck is comparable to that of a railway wagon.
At dawn that day, the police patrolled to the square of Hasuhai Toll Station of G6 Expressway, and saw a large truck coming from afar. When the truck drove into the entrance of the toll station, it made a "peep" sound, which was particularly harsh in the silent night. The police were alerted at once, because the sound was like the sound made by the hydraulic pump for "weighing", so they got off to check. At the same time, the toll station staff also came to the police, and the police said in a low voice: "This car is bad, there may be questions, let's go and have a look.".
However, after the preliminary inspection by the police, it was not found that the vehicle was equipped with a hydraulic pump, and the driver was also dishonest. However, the police were not careless. They simply went to the bottom of the car to look for it, and finally found that a hydraulic assembly was installed next to the sixth axle of the car bottom, and the steering lever was located in a relatively hidden position (on the left side of the driver) next to the driver's seat in the cab. It was easy to drive and was not easy to find when being searched. The assembly surface is as common as the ordinary load bearing parts of freight cars, which is confusing.
When the work is exposed, the driver is also frank and lenient. It turns out that the hydraulic pump installed on this vehicle was once different from the jack type hydraulic pump of the previous generation. The "model" hydraulic pump is installed on the bottom of the car and has the same parts as those on the car. When weighing and charging, the lifting lever of the hydraulic jack can lift the car body (or one-sided car body). When lifting, the pressure of the wheels against the pounds decreases. Each axle of the car presses over the scale in turn. It can be understood that the hydraulic jack is matched with a "hand" to lift the car for weighing, and the "hand" divides the one-sided weight, That is, the scale is less than the one-sided weight.
The new hydraulic pump is no longer like the previous generation demand truck that stops at the moment in front of the weighbridge. The whole process is realized in motion. The disadvantage is that the noise is relatively loud! Here, we remind the high-speed traffic police and toll station staff around the country to make progress and carefully inspect suspicious vehicles.
1、 Placed Hydraulic pump station Most of the assembled toll evasion vehicles are tense and overloaded trucks, which make a lot of noise when passing the lane. At this time, toll collectors should arouse enough attention.
2、 Most of the vehicles using the hydraulic pump to evade fees are heavy trucks. When weighing, they will stop for a period of time. After the front of the vehicle passes the weighbridge, the speed is suddenly very slow, or the front of the vehicle stops swinging.
What are the performance characteristics of the dual hydraulic grouting pump and the things to pay attention to? Henan Gengli grouting pump family analyzes the performance characteristics of the double hydraulic grouting pump and grouting control attention to the incident. The double hydraulic grouting pump is suitable for single liquid grouting and double liquid grouting. The dual hydraulic grouting pump is not only simple in layout, reliable in operation, but also has higher pumping pressure; Moreover, the grouting cylinder is more wear-resistant, has a longer service life, and can also inject and transport viscous slurry. The double hydraulic grouting pump is mainly used for tunnel excavation and protection, road, bridge, dam, mine construction, bottom disposal of high-rise buildings and various grouting construction projects.
1. The dual hydraulic pump station is designed for professional grouting, which can realize both single fluid grouting and dual fluid grouting. 2. Because it is fully hydraulic, small in size and light in weight, it is suitable for construction with wide limitations. Hydraulic pump station 3. The adjustable performance is relatively good: within the design limits, the pressure and displacement of the pump can be adjusted randomly. When the pressure exceeds the allowable pressure, the overflow valve will automatically open, and the hydraulic pump station's oil cylinder and working cylinder will stop working, playing a safety benefit. 4. In flammable and explosive construction sites such as coal mines, this series of hydraulic grouting pumps can also be safely applied by using explosion-proof motors. 5. The anti-seismic pressure gauge is set in the oil pressure system to reflect the working condition of the grouting pump. 6. Dual hydraulic grouting pump can also be used as clean water pump, sewage pump and mud pump.
Double hydraulic grouting pump grouting control Watch out 1. The grouting pump should be fixed at the horizontal position as far as possible to avoid distortion and folding of oil pipe and slurry suction pipe. Although the slurry suction pipe is shortened, its vertical spacing should not exceed one meter. 2. Regularly check the filter screen of the oil tank and the filter screen of the oil circuit, and clean them. Regularly replace the hydraulic oil. It is recommended to replace the hydraulic oil once a month or so. In summer, No. 46 hydraulic oil shall be used, and in winter, No. 32 hydraulic oil shall be used. Each time, about 45kg of hydraulic oil shall be changed. 3. The work garden should have enough water to facilitate work. 4. The hydraulic pressure of the grouting pump shall be checked regularly for discussion and shall not be loosened. 5. The construction driver shall have necessary grouting experience to ensure smooth construction. 6. The electric cabinet, motor and electrical appliance of the grouting pump shall be kept clean and dry, and the wires of the above components shall be checked frequently to avoid damage and power off. 7. When the hydraulic pump station carries the grouting pump, it is not allowed to have large fluctuations, and it is not allowed to randomly knock on various parts of the machine.
