Suction truck Mainly for urban and rural sanitation department to pump and transport manure and other sewage. Suitable for manure extraction, sewage, sludge slurry and liquids mixed with minor suspended debris, suitable for municipal sanitation, large and medium-sized industrial and mining enterprises, communities, schools, etc. Function Description Suction truck function description: Vacuum suction truck configuration: special parts from the power take-off, drive shaft, vacuum suction fecal pump, water and gas separator, oil and gas separator, multi-way valve, boom, feces tank, put feces Valves, suction manure nozzles, clean water tanks, manure windows, vacuum pressure gauges, pipe network systems, etc. hotline Suction truck This product is used to extract feces, sewage, sludge slurry and liquid mixed with small suspended debris, has high suction efficiency, self-absorption, self-discharge and direct irrigation and other characteristics, widely used in large and medium , Small towns, sanitation, municipal, agriculture, chemical industry, factories and mines, residential areas, vacuum suction pump can be self-priming. Suction truck working principle and structure Suction trucks are clean sludge and excrement cleaning vehicles in modern life. Their working principle is mainly the use of air pressure for suction and sewage disposal. The main operating element is a vacuum suction pump. When it is working, the engine passes through the gearbox and the power take-off drives the vacuum pump. When suction works, the vacuum pump draws out the air inside the tank to form a vacuum, and the dirt is pushed into the tank through the suction pipe under the action of external atmospheric pressure. In the event of blowdown, the vacuum pump reverses, drawing outside air into the tank and using the air pressure inside the tank to remove the dirt. In the process of work, in order to avoid contamination of the feces stains, it is necessary to use a water-gas separator to filter the air in the tank, and the filtered air is discharged out of the tank and the water flows back into the suction tank. The circulating oil in the vacuum pump can also be reused after being separated twice by the oil separator and can avoid contamination. During operation, the manure suction and sewerage operations of the suction truck can be adjusted by controlling the three-way and four-position valves. Pump vacuum pump structure and mission principle Suction truck vacuum pump is the key component of the suction truck. It mainly cooperates with the power take-off device, the three-way four-position valve, etc. to achieve vacuum and pressurization into the dwarf. At present, the commonly used suction truck is a unipolar rotary oil seal vacuum pump, the ideal task pressure is 200PA--8500PA, with convenient installation, high vacuum, high efficiency. The vacuum pump is mainly composed of a pump body, a rotor and its components, a pump casing, a rotary vane, a slip ring, a bearing cap and a helium removal device. The rotor is a consumable part. In order to facilitate the dismantling of the virtual toilet bowl, the center of rotation of the rotor deviates from the center of the pump body. The mission principle is that the eccentric rotor is driven by the power taker and the dwarf is inhaled into the compression chamber. When the pressure exceeds the specified value of the exhaust port, the tightening chamber is automatically opened, and the tight helium gas is discharged, so that the dwarf internal snorkel gas is Withdrawal, repeated cycles, dwarf internal vacuum. Suction truck discharge operation (1) Move the suction hose towards the storage tank. (2) Pull the rear handle of the four-way valve parallel to the ground and open the spill-proof valve so that the handle and the pipe axis can be parallel. (3) Hitch the transmission to neutral, then start the engine, disengage the clutch, pull the power take-off switch backwards to pull the file, and the vacuum pump starts to operate. hotline (4) After the discharge of the fecal fluid in the tank, the driver shall promptly push the power take-off handle forward to remove the gear, and the vacuum pump will stop running. (5) Close the fuel tank straight cock rotating handle plate and enter the axis of the e-mail box and close it. After the hose is rinsed, put it back into the walk-in box, close the side door, and make the suspender point towards the cab. (6) Move the suction truck away from the operating point. This large-scale unfit for rural use is unlikely to enter the farmyard, so it would be nice to use a three-wheeled slag-catcher in the countryside! The sales hotline suction truck is equipped with an import anti-overflow device to prevent feces and sewage from being sucked back into the vacuum pump system. The tortoiseshell design of the tank is permanently deformed. Install Hangzhou Veyron Vacuum Suction Pump (Italian Technology), which is ranked first in the national quality appraisal. The suction suction guide tube can be rotated 360 degrees. The discharge is self-discharge and pressure discharge. The float ball level controller is installed and the electronic alarm device is installed. . Suction trucks can be self-priming, self-discharging, and have the features of high vacuum and long suction range, which can meet the needs of different users in different use environments. Suction trucks are suitable for septic tank clean-up and transfer, urban pipeline cleaning and dredging, and plant biogas slurry and biogas residue cleaning. Suction truck components: oil-water separators, water and gas separators, special vacuum suction manure pumps, volume pressure gauges, pipe network systems, suction ducts, gravity valves, vacuum tanks, connected devices (as feces), fully automatic protection Overflow valve The nodular cast iron manhole cover is mainly made of nodular cast iron, and the quality of this manhole cover is related to the spheroidization rate. The common coating used to treat castings is antirust asphalt paint. Of course, the surface of nodular cast iron manhole cover is also treated by spraying antirust asphalt paint. Ductile iron manhole cover has an advantage, that is, because of its high strength and good toughness.
