Acid pump

First, the stainless steel 316L acid pumps (chemical pumps) Features: Built-in stainless steel, single (three) phase power supply, materials used 316L, is the only alternative to chemical pump dedicated submersible pumps. Second, stainless steel 316L acid pumps (chemical pumps) Use: Warning The pump must not run for flammable and other dangerous liquids warning should ensure that the operation of the pump must not run dry run the pump series QDN / QN running liquid water, micro-polluted water, sea water liquid maximum temperature of 40 ℃ maximum free travel Φ4mm suspension liquid PH value 4.0-10.0 maximum immersion depth of 5m installation elevation (sea level) noise maximum immersion depth of 1000meters (when the pump is diving, the noise disappears) Maximum on / off cycles / hour (equally spaced) power connector, ground warning must ensure that the pump voltage, frequency and power supply network is consistent shock hazard installer must ensure that the ground shock hazard is fitted with an automatic power flow must be guaranteed protection Single-phase single touch phase pump with grounded plug the power cord. Three-phase ground must be connected to the mains. 2, single-phase pump is equipped with overload protection built-in automatic thermal overload overload settings, so other protective devices are no longer needed. 3, three-phase pumps the rotation direction of the motor shaft rotation direction of the pump test will affect the head and water transport. Correct direction of rotation from the pump inlet to see is clockwise. 4, when using an extension cable, shall ensure to avoid voltage drop and keep the joints to dry for 5, outdoor switches or connectors should Covers and moisture measures. Do not touch the wet switch or touch switch with wet hands. 6, the wiring should be implemented professional qualifications electrician and should comply with the relevant safety standards. Run 1, when the pump is running, you have to pay attention to water level (particularly in the small-capacity operation), once the water level is not enough, it must prohibit the pump operation. If the pump is running for a long time in the absence of water, it will burn out the motor or coil. 2. The actual mention long? Degrees (from the surface to the destination) should not be less than a predetermined lifting height of 80% (lift height nameplate). 3, the voltage fluctuation range should be within 10% of rated voltage, otherwise it will reduce motor life, and even damage the motor. 4, when the pump is running, such as abnormal phenomena, such as abnormal sound, water, little or no water, it should immediately turn off the power, stop the pump running. When the pump is energized or wet, do not touch the pump. Starting 1. Before starting, check? Pump installation and power connection is correct. 2. Float switch connected directly to the control of the pump starting and stopping of the pump. Check that the float switch can move freely, and interference from other objects. 3. No float switch for pump structure, when the pump is completely immersed in water, the pump starts. If the motor is not completely immersed in water or run at more than 40 ℃ temperature in too long, the motor will be shutdown. When the motor coil temperature is too cold, thermal protection automatically transferred. 4. Start the pump and let it rotate a few seconds, the prosecution? Its startup, operation and direction of rotation (three-phase pump after, it was found wrong direction of rotation, rotation two phases should then start), found little or no flowing out, indicating the direction of rotation water pump failure, you should swing phase.
