Water truck related knowledge summary What is a sprinkler? Water truck definition 1: Second, sprinkler car overview and classification
Oxygen machine is one kind of product producing oxygen from air. There are small oxygen machine providing 3-10 liter per minute flow, mainly using at home. There are also big Industrial Oxygen Generator providing oxygen with flow rate up to 10000 Nm3/hr. From technology, there are pressure swing adsorption(PSA) , vacuum swing adsorptio (VSA)and cryogenic three types. The PSA type is for smaller flow rate within 300 Nm3/hr, from 300 to 3000 Nm3/hr, it is ok to use VSA technology. For bigger flow rate, normally use cryogenic Oxygen Plant.
No matter what technology, these oxygen machines all use oxygen in the air. All use Air Compressor to provide raw material, compressed air. Then the compressed air will be cleaned, dried for futher separation. After separation, the produced oxygen either directly goes to oxygen using point or they are compressed into high pressure such as 150 bars or 200 bars, then stored in cylinders and tanks.

It can also be used for temporary emergency firefighting.
Watering Cart Definition 3: (GB/T17350-2009)
With a pump, nozzle, so that the water has a certain pressure, used for spraying the road, dust and cooling effect of the tank-type special operating vehicles.
    Sprinklers Overview:
Watering Truck: The watering truck has the functions of carrying water, draining water, and emergency firefighting. It is equipped with pre-shooting, post-spraying and side-spraying, self-priming special pumps, pumps for pumping and draining, fire-fighting joints, free-flow valves, working platforms with tanks, and installation of green sprinklers. The guns can be rotated to adjust the amount of water ( Jets are columns, fog, drizzle).
    Sprinkler classification:
Sprinklers are categorized according to their use: divided into spray-type, flush-type, spray-wash-type sprinklers;
Sprinklers are categorized into chassis types: automotive, semi-trailer and trailer-mounted sprinklers;
Sprinklers are classified by capacity and can be divided into how many square meters or how many tons of sprinklers.
Sprinklers are categorized by brand: sprinklers can be divided into Dongfeng Sprinklers, Liberation Sprinklers, Foton Sprinklers, JAC Sprinklers, Hualing Sprinklers, Shaanxi Auto Sprinklers, Heavy Duty Sprinklers, and Beiben Sprinklers. and many more.
Optional configuration: The prices of sprinklers vary from place to place throughout China. Standard configuration sprinkler (greening sprayer, water tanker): front shower, side spray; high side shower; rear working platform with green sprinkler, can be adjusted into a column, with a range of ≥ 28m; can also be adjusted to fog Shape, range ≥15m. Optional medicine tray, fight drugs machine. It can also install advanced facilities such as medicine discs, drug pumps, anti-corrosion and anti-rust in the tank, multi-directional inlet and outlet water connections, solenoid valves, pneumatic valves, etc. to meet the needs of different users.
    Third, the structure of the sprinkler
The basic composition of the sprinkler: rust-proof tanks, communicating devices, special self-priming sprinkler pumps, pipe networks, spray outlets, working platforms, and second-class chassis.
Sprinklers optional configuration: GPS, universal sprinklers, electromagnetic valves, pneumatic valves, visual operating system, external power, disc.
    1. Chassis:
The chassis of special vehicles generally uses Dongfeng, Jiefang, Futian Auman and other types of chassis. Currently widely used are "Dongfeng Duba sprinkler, Dongfeng Duolika sprinkler, Dongfeng 140 sprinkler (long head), Dongfeng 145 sprinkler (flat head), Dongfeng 153 sprinkler (flat head), Dongfengtian Jin sprinkler, Dongfeng Tianlong DFL1250A8 sprinkler (after the double bridge).
    2, tank production:
Automatic production line tank production process is divided into: cutting, automatic welding puzzle, head spin forming, tank rolling and other domestic advanced production technology. Tank materials are mostly made of high-quality carbon steel plates. In special applications, 304 stainless steel can also be used according to the customer's needs. The volume of the tank body is "4 cubic, 5 cubic, 6 cubic, 8 cubic, 10 cubic, 13 cubic, 15 cubic" and so on.
    3, piping system:
By "pipes, valves, filter devices, outlets (pre-spray after sprinkler, side spray; high-side shower; rear working platform with green sprinkler antiaircraft guns).
     4, operating system:
The transmission is driven mainly by the engine . The power take-off mounted on the transmission drives the sprinkling pump. The sprinkling pump generates power and sprays the liquid inside the tank through the pipe network. Working range: Self-priming height: ≤7m, Sprinkling width: ≥14m, Maximum range: ≥28m; Can be adjusted into a column with a range of ≥28m; It can also be adjusted to a mist with a range of ≥5m.
    5, sprinkler pump:
Equipped with sprinkler, green sprayer high-power special sprinkler (Weilong pump), with fire joints, with self-flow valve, with self-priming function.
Optional equipment: It can be equipped with sprinkling discs, drug pumps, anti-corrosion rust inside the tank, multi-directional inlet and outlet connections, solenoid valves, pneumatic valves and other advanced facilities to meet the needs of different users.
    6, water sprayer:
The Dongfeng sprinkler is equipped with a duck-billed or round-headed nozzle in front of it, followed by a cylindrical sprinkler nozzle or a shower head nozzle, and a working platform at the rear, equipped with a water cannon. There are 8 nozzles on the back.
Sprinkler, green spray vehicle special features: Green sanitation function, suitable for urban sanitation and environmental sanitation, the use of quality leading high-power dedicated sprinkler pumps. After the rush (spray), sprinkle, with side spray (shower), with the back of the platform, install green sprinkler on the platform (cannon with heavy rain, moderate rain, drizzle, fog can be adjusted), with suction pipe, with fire Joints, with self-flow valve, self-priming self-discharge, optional 20 meters green spray reel, high-altitude operations, truck crane cargo and other functions.
  7, cab:
Sprinkler cab is divided into: pointed cab, or flat cab, also known as long cab, short cab.
Sprinkler power take-off box Description: Sprinkler is currently using Dongfeng, to release the series power take-off, pneumatic operation, operation switch pull back, take the force tooth into the mesh position, drive the water pump through the drive shaft, the switch back to the back, the pump stops jobs.
Sprinkler sprinkler function description: The sprinkler is equipped with a duck-shaped nozzle or a round-headed nozzle, followed by a cylindrical open sprinkler nozzle or a showerhead nozzle, and a working platform at the rear, equipped with a monitor. 8 nozzles at the rear (optional)
The water sprayer is generally used for flushing the street and plays a role of dust removal and cooling. The water sprayer can change the spraying direction and angle of the water sprayer by adjusting the nozzle thread. The water spray gun can be used for urban and rural landscape greening and emergency firefighting. Lian Peng mouth can be poured down the middle of the road to the dust from the sprinkler, play a role in cleaning the air.
Four, sprinkler function description
    1. Water suction operation:
(1) The sprinkler should be as close as possible to the operating point and parked;
(2) Open the side door of the walk-in box and take out the water-absorbing rubber hose so that it swings back without bending;
(3) The suction hose should be pumped into the water as deep as possible to ensure that the pipe end is always 300mm below the liquid level during the operation;
(4) Push the four-way valve handle to a vertical position with the ground;
(5) Hitch the transmission to neutral, then start the engine, separate the clutch, pull the power take-off switch backwards to pull the file, and the pump starts to run;
(6) The operator can pass through the observation lens on the upper part of the rear head. When the liquid level reaches the middle part of the sight glass, the operator should be informed. Colleagues should quickly pull the water suction hose off the water surface or close the four-way valve;
(7) After retracting the hose, return it to the walk-in box and close the side door;
(8) Leave the sprinkler away from the pumping point.
     2. Spraying operations:
(1) Pull the rear handle of the four-way valve to parallel with the ground, open the ball valve you want to spray (front punch, rear spray, side spray, shower), then start the engine and put the transmission into the gear, take the power take off device. The switch pulls back and pulls the gear, then the clutch is disengaged, the pump starts to run, and the water begins to spout;
