Vehicle and Trailer Classification" GB/T15089-2001

The current new standard GB/T3730.1-2001 replaces the old standard GB/T3730.1-1988;

The current new standard GB/T15089-2001 replaces the old standard GB/T15089-1994.

“Types and Definitions of Vehicle and Trailer Types” GB/T 3730.1-2001 is a generic classification applicable to general concepts, statistics, licenses, insurance, government policies and management basis; “Classification of Motor Vehicles and Trailers” GB/ T15089-2001 is mainly used for type certification, and is the basis for the scope of application of type-approved technical regulations.

The promulgation of these two new national standards establishes the concepts of passenger cars and commercial vehicles on the basis of division by purpose. In addition, there are classifications of cars in the old abolition standards, and the current standard cancels the terminology of cars. However, considering that the term “car” is widely used in our country, in the current classification, the models that were considered to belong to cars in the past were basically classified in the category of basic passenger cars. Its purpose is not to deviate from the concept of people in the past, causing confusion.

In the past, some Cherokee models were included in the sedan category, and some Cherokee and low-priced SUVs such as the Great Wall Sev were clearly included in the light buses. It is obviously unreasonable. Now belong to a class.

Sprinklers are divided into spray type, flush type, and spray-flush type according to the purpose; according to the type of chassis, they are divided into automobile type, semi-trailer type and trailer type; according to the water tank capacity, a certain cubic meter (ton) of sprinkler can be called. .

Sprinkler brand classification: Sprinklers can be divided into different types according to the chassis: Dongfeng Sprinkler, Liberation Sprinkler, Foton Sprinkler, JAC Sprinkler, Hualing Sprinkler, Shaanxi Auto Sprinkler, Heavy Duty Sprinkler, Beiben Sprinkler, etc. Wait.

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.

1. Requirements for water

When the sprinkler uses the river ditch or pond as a source of water, pay attention to that all the ends of the suction pipe are not in the water. In order to avoid inhaling stones or more sand and drift debris, the suction pipe end is generally provided with a filtering device, and it is forbidden to remove the filtering device during the water absorption. If the water source is shallow, it is necessary to dig up the water absorption area in advance so as to ensure that it does not contain impurities and air. The water pump requirements for different sprinklers are different. The clean water pump requires no impurities in the water. The turbid water pump requires no stones and excessive sediment in the water.

2. Add water diversion

Every time the centrifugal pump absorbs water, a certain amount of water must be added to the pump. After the addition, the water inlet must be closed. When the self-priming pump is used for the first time, it is necessary to add water, and it is unnecessary to add water afterwards.

3. The inlet pipe must be vacuumed

The water inlet system must maintain a certain degree of vacuum before it can suck water into the tank. The inlet pipe system must be sealed reliably, the hose can not be damaged, the hard pipe can not have cracks, otherwise it will have a phenomenon of air leakage, which will result in the situation that it cannot suck water.

4. Parking stalls

Before the water sprinkling vehicle or water sprinkling, the power take-off device must be parked.

5. Winter water release

Before the advent of winter, the water in the pumps and pipes should be vented to prevent freezing. The northern part of the country is generally no longer under construction during the severe winter. Therefore, after the construction is completed, the water in the pump and the water pipe will be drained immediately to prevent future problems.

6. Watering precautions

The front sprinkler of the sprinkler is located at a low position, close to the ground, the spray pressure is relatively large, and can be used for flushing the road surface; the position of the rear sprinkler is relatively high (the sprinkler is generally installed on the left and right sides of the sprinkler), and the sprinkler surface is wide, and can be used for highway construction and watering. When the rear nozzle is used, the front nozzle should be closed; when using the adjustable nozzle, the width of the sprinkler can be adjusted as needed. The wider the sprinkler width, the less the amount of intermediate overlap and the more uniform the sprinkler density.

7. Lubrication and fastening

During the process of use, lubrication points of the transmission assembly should be regularly lubricated, and the joints should be tightened frequently to ensure normal use.

8. Regular sewage

The water tank of the sprinkler truck is provided with a sewage pipe. The inlet of the pipe is the lowest point of the water tank. After a period of use, the discharge pipe switch should be opened periodically to remove the accumulated debris from the tank until the water becomes clear.

Sprinkler components:

The basic composition of the sprinkler: rust-proof tank body [1], communicating device, special self-priming sprinkler pump, pipe network, spray outlet, working platform, two types of chassis.

Sprinkler optional configuration: GPS, universal sprinkler, electromagnetic valve, pneumatic valve, visual operating system, external power, disc.

First, special vehicle chassis: generally use Dongfeng, Liberation, 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).

Second, the tank production: the use of automated assembly line tank production process is divided into: cutting, automatic welding puzzles, head spin spinning molding, 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.

Third, the pipeline system consists of "pipes, valves, filtration devices, outlets (before the after the spill, side spray; high side shower; after the work platform, with green sprinkler gun).

Fourth, the operating system: mainly driven by the engine gearbox, gearbox installed on the PTO driven sprinkler pumps, sprinkler pumps generate power, the liquid inside the tank through the pipe network to spray out. Working range: Self-priming height: ≤7m, Sprinkling width: ≥14m, Maximum range: ≥28m; Adjustable into a column with a range of ≥28m; It can also be adjusted to a mist with a range of ≥15m.

5. Sprinkler pump: equipped with sprinkler, green sprayer high-power special sprinkler (Weilong pump), with fire connector, 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.

Six, sprinkler sprinkler

In front of the sprinkler, there is a duck-billed or round-headed nozzle, followed by a cylindrical sprinkler nozzle or a shower head nozzle. At the rear there is a working platform 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, optional 20 meters green spray reel, high-altitude operations, truck crane freight and other functions
