There are many ways to use sand and gravel pumps, and the following are two common methods:
1. Install a check valve on the head of the pipe that extends underwater, and then fill it with water to start the pump. But this method may frequently inject water.
2. Add a small buffer tank in front of the pump, with the high level gate connected to the groundwater pipeline, and the low level gate connected to the pump, causing noise only at the inlet. Leave a pipe opening at the top and install a valve accordingly. When using, add water from the top to the full buffer tank and close the valve. Start the pump. This method is generally suitable for irrigation once without special circumstances.
3. Install a water level controller at the inlet of the pump to monitor the water level and control the start and stop of the pump at any time. When the water level reaches the set value, the controller will automatically cut off the power supply to avoid equipment damage caused by dry idling.
When using a sand and gravel pump for water diversion, it is necessary to ensure good sealing at the pipeline connection to prevent leakage. Special sealant or rubber washers can be used to reinforce the connection, ensuring that the water quality is not contaminated.
If it is necessary to transport the water source to a higher location, a booster pump can be considered to increase the water pressure in order to better drive the sand and gravel pump. The booster pump can be used in series with the sand and gravel pump, or a separate booster system can be set up.
When using a sand and gravel pump for water diversion, attention should be paid to observing the water flow to ensure smooth flow and no abnormal noise. If poor water flow or abnormal noise is found, the equipment should be checked in a timely manner to avoid affecting the quality and service life of the project.
7. Regularly maintain the sand and gravel pump, including cleaning impurities, replacing worn parts, etc., to ensure the normal operation of the equipment. At the same time, regular inspections and repairs should be carried out on the sand and gravel pump according to the manufacturer's requirements to ensure safety and reliability.
8. When using in winter, be careful to prevent the sand and gravel pump from freezing. Insulation facilities can be installed at the inlet and outlet, or antifreeze can be used to reduce the freezing point of water. At the same time, it is also necessary to ensure that the sand and gravel pump can operate normally in cold weather and will not be damaged due to icing.
During the water diversion process of the sand and gravel pump, attention should be paid to complying with relevant regulations and safety regulations to ensure the smooth progress of the project. For example, obvious warning signs should be set up at the construction site to remind past personnel to pay attention to safety. At the same time, attention should also be paid to protecting the environment and avoiding pollution of water sources.
With the development of technology, the performance and functions of sand and gravel pumps are becoming more and more perfect. When selecting and using sand and gravel pumps, appropriate models and configurations can be selected based on engineering needs and budget. At the same time, intelligent control systems can also be considered to achieve remote monitoring and automated management of sand and gravel pumps, improving work efficiency and safety.
