Many users who purchase a sprinkler will ask a question, is there any skill in the process of using the sprinkler, today Xiao Bian will give you a summary of several sprinkler tips for your reference.

1. Requirements for water quality

When the sprinkler uses river ditch or pond water as a water source, the end of the suction pipe should be completely submerged in water. In order to avoid inhalation of stones or sediment, drift debris, etc., the suction pipe end is provided with a filtering device, which prohibits filtering when water is sucked. The device is removed. If the water source is not very deep, it is necessary to dig the water absorption deeper in advance to ensure that it does not contain debris and air. Different pumps have different requirements for water sources. With any impurities, the turbid water pump can not have stones and excessive silt in the water.

2. Add water diversion
Every time the centrifugal pump absorbs water, it is necessary to add a certain amount of water to the pump. After the addition, the water inlet must be closed. When the self-priming pump is used for the first time, it must be remembered to add water. After that, it is not necessary to add water.

3. The inlet pipe must be vacuum
Water inlet pipe system must maintain a certain degree of vacuum before the water can be sucked into the box. 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 leakage phenomenon, but also Can cause inability to absorb water.

4. Parking stalls
No matter if the sprinkler is before water absorption or before the water is sprayed, the power take-off device must be stopped while parking.

5. Winter water release
Before the advent of winter, the water in the water pump and the water pipe should be vented to prevent freezing. The northern part of the country is generally not exposed to severe winter construction. Therefore, after the completion of the construction, the water in the pump and the water pipe should be drained immediately to prevent future accidents.

6. Watering precautions
The position of the front sprinkler of the sprinkler is relatively low, close to the ground, and the spray pressure is large, which can be used to flush the road surface; the rear nozzle is relatively high in position and the sprinkler surface is wide, and can be used for highway construction and water spraying. When using the rear sprinkler, the front nozzle is firstly used. Close; When sprinkling with the adjustable sprinkler, 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
When using, it is necessary to lubricate the lubrication points of the transmission assembly regularly and tighten the joints to ensure normal operation.

8. Regular sewage
Sprinkler tank with a sewage pipe, the import of the pipe is the lowest point of the tank. After a period of time after use, should be regularly open the sewage pipe switch, the tank debris accumulated until the water becomes clear.

The above is a summary of the eight techniques used, the correct use of the method can not only reduce the failure of the sprinkler, but also improve work efficiency.

 


Excavator cylinder oil seals

â‘ Hardness:

Due to the scientific synthesis of high-molecular polyurethane elastomer materials using iron rubber, the higher the hardness, the higher the modulus, the smaller the elongation, and the better the wear resistance and heat resistance. Well, in the range of minus 35 degrees Celsius to 100 degrees Celsius, and at a pressure of 60 to 70 MPa, the maximum sealing performance can be guaranteed.

Oil seal

â‘¡Pressure resistance:

The use of viscoelastic seals made of nitrile rubber is the most complete protection against damage caused by back pressure. In the range of minus 55 degrees Celsius to 100 degrees Celsius, and under a pressure of 21MPa, due to the rubber The seal is often in a compressed state, so the compression performance of the rubber seal must be considered. It not only achieves enhanced anti-climbing performance and low friction resistance, but also has good performance in dealing with special low-temperature oil, and can also be used in combination with Anti-wear Ring double-purpose retaining ring BRL type.


SPGW

â‘¢Prevention of oil leakage:

Sealing products made of polytetrafluoroethylene and nitrile rubber/PTFErubber; or seals made of nylon resin and nitrile rubber, which can be used in a wide range of applications with large pressure changes and fast sliding speeds According to the working condition, the input hydraulic pressure cutout is designed on the end face of the polytetrafluoroethylene ring to prevent penetration leakage. The maximum working temperature environment is minus 40 degrees Celsius to 160 degrees Celsius; the maximum working pressure is 50MPa.
