| It is widely used in agricultural irrigation, industrial and mining drainage, waterscape fountains, flood control and drainage, etc. |
| Usage Environment |
The use conditions of QY oil-immersed submersible pump: The flow rate at the outlet of the electric pump shall not be greater than the rated value (used within the specified head range); the diving depth shall not exceed 5 meters. If it exceeds 5 meters, please declare it when ordering; the water temperature shall not exceed +40℃; the PH value shall be between 5 and 9. |
| Product Advantages |
Structural and performance advantages: The pump and the machine are integrated, with a compact structure, light and easy to move, which is convenient for installation and use, and easy to move to different work sites. No water diversion is required, and it is easy to use, saving the tedious water diversion operation before use and improving work efficiency. - Sealing and heat dissipation advantages: The motor is filled with mechanical oil, which improves the working conditions of the mechanical seal and effectively prevents external water from entering the motor. The oil can quickly conduct the heat inside the motor, with good cooling effect, reducing the temperature rise of the motor and increasing the overload capacity of the submersible pump. At the same time, the bearings work immersed in oil, and lubrication and cooling are guaranteed, making the bearing life longer than other types of submersible pumps. - Safety and durability advantages: The overall mechanical seal is durable, safe and reliable. Key components such as motors have good insulation performance, withstand high pressure, and have a long service life. They can adapt to a variety of complex working environments, reduce the probability of failure, and reduce maintenance costs. - Application scope advantages: There are a variety of calibers and powers to choose from, and a wide flow range, ranging from 10 cubic meters to 550 cubic meters per hour, which can meet the water supply and drainage needs in different scenarios, such as agricultural irrigation and drainage, garden sprinkler irrigation, fountain water supply, well water extraction, water tower water delivery, urban construction, industrial and mining water, aquaculture water supply and drainage, etc. - Material and appearance advantages: The pump body is made of all cast iron, with electrophoresis technology and metal paint design, which can effectively prevent corrosion and rust, extend service life, and has a more beautiful appearance, suitable for various outdoor environments. |

| Product Usage |
Agriculture - Farmland irrigation: In farmland irrigation, QY oil-immersed pumps can transport river water, well water and other water sources to the fields to meet the water needs of crop growth, such as irrigation of rice fields. - Flood control: In the rainy season, it can quickly drain the accumulated water in the farmland to prevent crops from being affected by waterlogging and ensure the normal growth of crops. It can also be used for flood control and drainage in depressions and polder areas. Gardening can be used for sprinkler irrigation and water fountains in gardens to provide precise water supply for garden plants, maintain plant growth, and create beautiful waterscape effects. Industrial - Water supply and drainage for industrial and mining enterprises: Provide production water for industrial and mining enterprises, or discharge industrial wastewater, etc., to ensure the normal production and operation of enterprises. - Mine underground drainage: In general mines, QY oil-immersed pumps can be used to drain the accumulated water in the mine to ensure the safety of the underground working environment. Urban construction - Urban high-rise water supply: Water can be transported to water tanks or water towers in high-rise buildings to provide living water for residents and meet the water needs of urban high-rise residential buildings. - Municipal water supply and drainage: In the city's water supply and drainage system, it is used to extract and transport clean water to ensure the stability of the city's water supply. It can also be used in the city's drainage system to assist in the removal of rainwater and sewage. In the ship field, it is mainly used for drainage of the ship's bottom, timely discharge of accumulated water in the cabin, to prevent the ship from affecting navigation safety due to excessive water accumulation, and to ensure the normal operation of the ship. |
| Product Operation Guide |
Pre-installation inspection - Check the pump specifications and performance parameters, such as flow, head, power, etc. - Check whether the oil hole screws of the upper and lower covers and the special screws for pressure testing in the middle of the outlet box are loose and leaking. It is strictly forbidden for users to move the pressure testing screws. - Check whether the cable is damaged. If it is damaged, it needs to be replaced. Installation and preparation - Ensure that the inner diameter of the water outlet pipe is compatible with the diameter of the electric pump. - Put it vertically in the water, the diving depth is 0.5 to 3 meters, and it must not sink into the mud or be placed horizontally. A bamboo basket or wire basket can be used to prevent debris from clogging the impeller. - The yellow-green two-color core wire must be grounded. If there is no fixed ground wire, a 2-meter metal rod can be buried in a damp place as a ground wire. Pre-start inspection - Exhaust the air in the pump. - Use a 500V megohmmeter to measure the insulation resistance of the motor stator winding to the ground in the cold state. It should not be less than 5MΩ, otherwise it should be used after dehumidification. - Idle for 1 minute on land to check the operation and direction. If it is reversed, exchange any two phases of the three-phase core wire. Operation precautions - The power capacity and voltage must be within the specified range. The cross-sectional area of the wire should be thickened when far away from the power source. - When the pump is powered or pumping water, washing, swimming, and letting livestock enter the water are prohibited to prevent leakage. - Do not pump water with a large amount of sand or mud. - Pay attention to the water level to avoid the pump running dry. |
| Frequently asked questions |
The motor does not start: power failure, motor failure or protection device action. The water pump does not produce water: the impeller is blocked, the water suction pipe has problems, the water level is too low or the water pump is reversed. The water pump has insufficient flow: the impeller is worn, the filter is blocked, the head is too high or the voltage is insufficient. The water pump has abnormal noise: the impeller and the pump casing are rubbing, the bearing is damaged, the water pump is cavitated or foreign matter enters the pump body. The motor is overheated: overload operation, poor heat dissipation or the motor winding is short-circuited and grounded. The motor leaks oil: the seal is aging and damaged, the oil mark tube is broken or the motor end cover bolts are loose. |
