Sewage suction trucks and suction trucks are mainly used for septic tank clean-up and transfer, urban pipelines are cleaned and dredged, and plant biogas slurry and residue are cleaned up. What are the details you should pay attention to when buying a sewage suction truck or a suction truck? If you do not want to sum up yourself carefully, this Tip of Winning by Xiagong Chusheng Sewage Absorber Truck and Suction Truck Factory should be your must-read: First, choose the company. Before purchasing the tanker, the user first chooses a powerful brand tank truck manufacturer with excellent product quality and after-sales service. Fourth, look at the configuration. The configuration should be reasonable and practical. Seventh, sign the product purchase and sale contract. Signing the product purchase and sales contract clearly writes detailed requirements and configurations. After the contract is signed, the manufacturer strictly organizes the production according to the contract, and the finished production is put into storage. Payment is made according to the contract inspection. All in all, careful attention, patience, and a lot of attention will be given to the most cost-effective sewage suction trucks and suction trucks.
U-tube refers to a heat exchange tube shaped like a U, which is an important part of a U Type heat exchanger. Advantages of U-shaped tube: The U-shaped tube heat exchanger has only one tube plate, both ends of the tube are fixed on the same tube plate, the tube can be stretched freely, no thermal stress, and the thermal compensation performance is good; the tube side adopts double tube side, The process is longer, the flow rate is higher, the heat transfer performance is better, and the pressure bearing capacity is strong. The tube bundle can be drawn out from the shell, which is convenient for maintenance and cleaning, and the structure is simple and the cost is cheap. The disadvantage of the U-shaped tube is that due to the limitation of the radius of curvature of the bend tube, the arrangement of the heat exchange tubes is less, the innermost tube spacing of the tube bundle is relatively large, the utilization rate of the Tube Sheet is low, and the shell-side fluid is easy to form a short circuit, which is harmful to the transmission. When the tubes are leaked and damaged, only the U-shaped tubes at the periphery of the tube bundle are easy to replace. If the inner heat exchange tube is damaged, it cannot be replaced, but can only be blocked. Moreover, one damaged U-shaped tube is equivalent to two damaged tubes, and the scrap rate is relatively high.

Second, see the performance
(1) Attention should be paid to the quality of the sheet, vacuum sealing, and poor material that can easily cause problems such as deformation of the can body.
(2) Choice of vacuum package, pressure capacity and temperature difference perception.
(3) After the selection of self-flow valve, according to the local operating environment, temperature difference and other options.
Third, the sewage suction truck, suction truck composition and price. Sewage suction and suction trucks are mainly composed of tanks, vacuum pumps, power take-off devices, four-way valves, water and gas separators, oil and gas separators, return tanks, booms, and locking mechanisms. Different chassis, different engines, different national emissions, different volume of tanks, and different parts of the accessories constitute the price of sewage suction trucks and suction trucks. When the user chooses, it is necessary to determine the main sewage suction trucks and suction trucks required. The parameters, suction manufac- turer can select the appropriate cost-effective suctioning manure as required.
Fifth, security is good, easy to control.
