In general, there are many kinds of common decontamination vehicles, such as snow shovels, sewage suction trucks, scrubbers, and sprinklers. Today we mainly introduce the main functions of the Dongfeng 153 decontamination vehicle, also known as the sewage suction truck, and its installation and What need to pay attention to use? The core components commonly used in sewage suction trucks and other sanitation systems are mainly rotary-plate type steel structures. After decades of technical updates, the domestic sewage suction trucks are mainly compact and reasonable. The general sewage suction trucks are mainly composed of the following: Several parts are composed of pump body, rotor and shaft assembly front and rear pump cover, rotary vane, bearing cap sealing device and slip ring and other components. The structure is simple and beautiful, and it is easy to repair and repair.
Sump cleaning car vacuum pump installation and requirements
The vacuum pump installation requirements of the sewage suction truck are relatively strict. To ensure the sealing of the sewage suction truck and the connection of vacuum pump connections after welding, firstly to ensure a seamless connection, the welding slag and dirt in the pipeline must be cleaned and then cleaned. Pump connection.
In the process of using the sewage suction truck, it is also necessary to pay attention in many places. When welding the pipeline and cleaning the welding slag, the cover of the inlet and outlet ports must be tightly closed to prevent the dirt from falling into the sewage suction truck during welding. The pump may not operate or rotate.
When installing the vacuum pump, the pump needs to be fixed in the ideal position of the car beam, the position of the pump, the left and right, and the front and back, determined by the shaft axis of the output shaft of the power take-off device. The inclination of the connection between the pump shaft and the output shaft of the power take-off device shall not be greater than 7 degrees and shall be as close as possible to the force taking device.
When installing, be sure to handle it gently, and avoid hitting and violent impact. Before use, it is necessary to add about 200 milliliters of water to the pump to clean the vacuum pump oil and combine the hand-type booster rod to run the pump for a week. Of course, we must choose the correct direction of rotation. If the direction is not correct, not only will the vacuum not be used, but the pump will also suffer a certain degree of damage.
When the sewer truck is used for the first time, low-speed operation (≤300 rpm/2 minutes) is generally required at no-load, and then the leak and temperature rise of the pump body are checked. According to the difference between the capacity of the sewage tank and the engine power, if the vacuum pump speed is too high during the use of the sewage suction truck, the rotor will generate heat; if the speed is too low, knocking of the engine will be caused, and other components will be caused. The additional impact will affect its service life, so the appropriate working speed plays a crucial role in the use of the sewage suction truck.
In addition, the sanitation workers must maintain the stability of the car body during the operation of the sewage suction truck and avoid hydraulic lifting and unloading on the inclined road surface. If the hydraulic road is lifted and lifted on the inclined road surface, uneven road surface will cause the weight of the car body to lean to one place. , resulting in distortion of the parts of the place, and the capacity of causing a roll-over accident.
To sum up a brief introduction of the Dongfeng 153 decontamination truck, I hope to have some help for you, for you to solve doubts is the greatest value of this article, more related issues you can leave a message in our article below, we will promptly You reply.
