User operation guide
Starting from September 1, 2010, Guangzhou's Pearl River Delta region will implement the National IV emission standard. At that time, the country's three-emission motor vehicles will not be able to license in the region, and many national first-tier cities will continue to implement the three national emission standards. The three national emission standard engines are divided into three types. One is the high pressure common rail technology, which is often referred to as the EFI engine. The second is the single pump, that is, the oil pump oil supply engine. The third is EGR. A secondary exhaust engine is equipped with a tail gas recycling technology that has reduced vehicle exhaust emissions.
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. Different sprinkler pumps have different requirements for water sources. Clean water pumps require no impurities in the water. Turbid water pumps require 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.

Cast Alnico Magnet

Alnico materials (composed predominantly of aluminum, nickel, and cobalt with minor amounts of other elements including titanium and copper) permit design latitudes providing high indications, high energies and relatively high coercivities. AlNiCo Magnets are characterized by excellent temperature stability and good resistance to demagnetization from vibration and shock. Alnico magnets offer the best temperature characteristics of any standard production magnet material available. They can be used for continuous duty applications where temperature extremes up to 930F can be expected. Alnico Magnet, alnico magnets, alnico bar magnet, alnico horseshoe magnet

Alnico magnetsl are manufactured through either a casting or sintering process. Alnico magnet is very hard and brittle. Machining or drilling can not therefore be accomplished by ordinary methods.Holes are usually cored in at the foundry. Magnets are cast or sintered as closely as possible to required sized so that abrasive grinding to finish dimensions and tolerances is minimized

Specialized casting techniques used to achieve the unique crystalline grain orientation found in the alnico 5 and 8 grades.These anisotropic grades are designed to produce high magnetic output in a specified direction.Orientation is achieved during heat treatment, by cooling the casting from 2000F at a controlled rate within a magnetic field which conforms to the preferred direction of magnetization. Alnico 5 and Alnico 8 are anisotropicand exhibit a preferred direction of orientation,Magnetic orientation should be specified on your drawing when you send an order to us. alnico magnet, alnico magnets

Cast Alnico 5 is the most commonly used of all the cast Alnico's .It combines high indications with a high energy product of 5 MGOe or more and is used extensively in rotation machinery, communications, meters and instruments, sensing devices and holding applications. The higher resistance to demagnetization(coercive force) of Alnico 8,cobalt content to 35%,allows this material to function well for short lengths or for length to diameter ratios of less than 2 to 1.

Sintered Alnico materials offer slightly lower magnetic properties butbutter mechanical characteristics than the cast Alnico materials.Sintered Alnico magnets are most suitable in small sizes(less than 1 oz.)in this process. The desired mix of metal powder is pressed to shape and size in a die,then sintered at 2300 F in a hydrogen atmosphere.The sintering process is well suited to large volume production,and results in parts which are structurally stronger than cast magnets.Relatively close tolerances can be achieved without grinding. alnico magnet, alnico magnets

The Characteristics of Alnico Magnet:

*Small changes in magnetic properties to temperature effects

*Maximum working temperature can be as high as 450oC~550oC.

*Low coercive force.

*Strong corrosion resistance capability,no coating needed for surface protection.

Typical Applications for Alnico magnet:

Widely used applications such as instruments and meters which require very stable temperature properties.

Electronic ignition systems, watt bour meters, volt-amp meters. medical instruments, industrial motors, magnetic reed switches, generators, hand tools, vending machines. alnico magnet, alnico magnets
