Sprinkling water pumps is very important for a sprinkler, so our usual maintenance and maintenance is very important. If the sprinkler does not absorb water, follow these steps to diagnose quickly:
The first step to check the switch, first check the water pump suction and outlet switch is turned on, the pump is a self-priming pump, the first time you want to irrigation water.
The second step is to inspect the filter screen. When the water pump is not smooth, check the front section of the suction pipe for debris blocking the water inlet. Then check the inlet pipe line by section to see if there is a leakage failure.

The third step is to check the degree of vacuum, and the commonly used pump water diversion height should be less than 5 meters. Then check whether the pump oil seal is damaged. The leakage of the pump shaft affects the vacuum degree. The seal should be replaced. When the engine speed is too low, it cannot reach the When the degree of vacuum is required, the throttle is adjusted so that the rotation speed is about 1700 rpm, and the engine speed varies depending on the gearbox.

The fourth step is to check the power take-off and check whether the power take-off is working or not. The power take-off and the drive shaft can cause the water pump to stop working.

The fifth step to listen to abnormal sound, check the pump speed is normal, pay attention to whether there is any abnormal sound, to determine whether because of debris wrapped around the leaves of the pump can not rotate properly. However, it is important to note that the pump cannot be idling for a long time during the test. Otherwise, the service life of the pump will be shortened due to the high temperature of the pump.
When the water pump does not discharge water, if the fault cannot be eliminated after detailed inspection according to the above steps, check whether the outlet water filter or the pump body is clogged because the uncleaned water tank is too dirty for a long time.
It's also important to develop good habits. The water irrigation should be cleaned regularly. In winter, the watering truck must be used to drain water from the water tank and pump body to prevent the tank body and the pump from freezing.

Heat Treated Steel Bar And Tube

HEAT TREATED STEEL BAR AND TUBE

Heat treated steel bar is produced by heating and cooling in different temperature based on the steel grades to improve the steel bar mechanical properties or machinability for various industrial applications. Heat treated steel bar includes annealed steel bars, Normalized Steel Bar, quenched and temper qt steel bar.

Annealed Steel Bar has better ductility and lower hardness, which can be easier to be machined. The annealing processing is usually widely used for steel grade with higher carbon content above 0.5%. However, some low carbon steel also requires to do annealing for special usage such as 20CrMnTi gear steel. For some special material such as 20CrMnTi gear steel and GCr15 such bearing steel, spheroidizing annealing is often required.

Normalized steel bar sometime is also one kind of annealing processing. It mainly changes the grain to remove the impurities in steel and improves the strength and hardness. For some hot rolled steel bars, to keep the basic mechanical properties, normalizing is often used.

Quenching and Tempering, abbreviated as Q&T is a king of processing that strengthen or harden steel bars by heating the materials and then cooling in water, oil or other liquid medium, that rapidly the change from austenite to perlite to get the proper properties for various usage. The quenched & tempered steel bar materials are usually with carbon from 0.30% - 0.60%, it is widely used as merchant bars in components of various machines.

Qt Bar

Our advantages on producing heat treated steel bars:

1) Big stocks of hot rolled round bars or wire rods as raw materials

2) Wide range of Cold Drawn Steel Bar sizes: from 10mm to 150mm

3) Different cold drawing medias powder or oil to get different surface

4) Straightening machines to get better straightness up to 0.5mm/m

5) Grinding and polishing machines to get better roughness upto 0.4um

6) Heat treating furnaces to adjust the mechanical properties

7) Full sets of testing equipment to test the sizes, mechanical properties and microstructure.

8) Multiple packages to avoid broken packages and anti-rusty
