Fountain pump features and installation and use of matters

[Asia Pump Network News] Waterscape Fountain Pump Features 1, the use of high-tech materials, improve motor corrosion resistance. 2, the impeller adopts special material to prevent the impeller from loosening. 3, leakage protection measures: the use of constant potential grounding device. 4, On the basis of the original ordinary pump, according to the request of the special fountain pump, after many tests, the company continuously develops technically and continuously improves the processing materials so that the special fountain pump can be started frequently and is completely suitable for the use of the musical fountain. 5, stainless steel filter shield, three-phase four-wire cable. 6, high-power fountain pump can be lying down. Can provide a variety of models. Waterscape fountain pump QSP fountain pump Notes: 1, equipment grounding submersible pump to take protective ground is the national compulsory standard requirements. Only to take protective ground, in order to ensure the safety of personal use. If there is no protective grounding, once the shell leakage, resulting in submersible pump water outlet and water pumping live, endangering the safety of humans and animals, while wasting a lot of electricity. If the submersible pump metal shell and meet the national standard grounding (grounding resistance is not greater than 4Ω) ground connection, when the submersible pump housing leakage, the current through the submersible pump metal shell, the protection of grounding wire, grounding, earth, the work of the transformer The ground wire and the power supply form a closed circuit. When the leakage current is too large, especially when the fire line hits the shell, the protection device of the submersible pump can be actuated (the fuse blows or the air switch is tripped) to cut off the power supply of the leakage submersible pump. 2, the installation of leakage protection submersible pump work in the water, easy to cause leakage of electricity loss or even lead to electric shock accident. If equipped with leakage protector, as long as the submersible pump leakage current value exceeds the leakage current protection device (usually not more than 30mA), the leakage protector will cut off the submersible pump power supply. 3, abnormal power supply voltage when the boot voltage is too high and too low will make the submersible pump temperature is too high, shorten the service life or even burn the submersible pump. Rural areas due to the low voltage power supply line is longer, the line voltage is too low, the beginning of the voltage is too high. Therefore, when using the submersible pump, the operator must observe the power voltage value at any time. If it is lower than 10% of the rated voltage, higher than 10% of the rated voltage or the current is greater than 20% of the rated current of the submersible pump, immediately Shut down and avoid power failure when the power supply is abnormal. 4, the motor rotates in the opposite direction Now there are many types of submersible pumps forward and reverse can be effluent, but the reversal of the small amount of water, the current is large, reversing a long time will damage the motor windings. Therefore, the submersible pump should be connected to the power before the water to check the rotation direction is correct. If the three-phase submersible pump impeller reversed, should immediately shut down, replace the three-phase cable in the core of any two-phase wiring can be. 5. Long-term overload work To avoid long-term overload work of submersible pump, do not use low-lift pump for high-lift work, do not pump water with heavy sediment (heavy mud), and keep an eye on whether the current value is within the specified range Inside. If you find that the current is too large, should stop checking. In addition, the submersible pump uses water as the cooling source, therefore, the submersible pump should not be dehydrated for too long. 6, frequent switch submersible pumps should not be too frequent start, it is because the submersible pump stalls will produce reflux, if immediately boot, the motor load will start, leading to start-up current is too large. Therefore, after shut down, the water in the tube must be reflowed before it can be started again. Generally, it takes about 5 minutes. 7, the use of submersible pumps in the mud environment If you sink into the mud in use, can lead to poor heat dissipation and burn the motor windings. Therefore, submersible pumps must not be used in silt environments. In order to prevent the submerged pump from sinking into the silt, the silt in the working environment should be removed before the submersible pump launches. If necessary, a fence guard should also be used to cover the submersible pump so as to prevent waste from blocking the water inlet fence and causing the motor to generate heat , Poor water. 8, after long-term deactivation on the water regardless of submersible pumps do not ask if not continuous use after going down, a long time will rust, leading to not start. Therefore, the disabled submersible pump should not be placed on the water regardless of the need to be switched on once a week, run 5 ~ 10min. Long-term non-use, it is best not to soak in the water for a long time, should be placed in water running for a few minutes, clean the pump inside and outside the mud, and then proposed water dry, a major inspection, disassemble all parts for overhaul, scrub, rust Detergents, replacement of wearing parts, and then reassembled, painted rust on the dry, non-corrosive gases in the warehouse.
