QH type submersible pump motors, pumps, pipes into one, the outer cylinder is both too waterways, but also motor cooling water chamber, compact, easy to install, is the frequent fluctuation of the water level along the river, the lake region drought, drainage, flood control pumping stations and sewage treatment works most scientific and rational models. Greatly simplifying civil works pumping station project cost savings, reduce the mounting area, and high operating efficiency, reliable operation; afraid of drowning, has power that is able to work, especially for post-disaster rescue flood zone; compact structure, flow, good performance, as advanced tech products; pump running, low noise, vibration small, durable, safe and reliable; unmanned pump stations can be achieved through a special control, according to the set level automatic start and stop, but also realize remote automatic control, low management costs with huge economic and social benefits. QH-diving submersible motor pump configuration instructions for dry, at the top of the pump and the pump fused appearance of the work of water flowing from the motor, can better cool the motor. Motor winding has thermal protection devices, motor stator chamber and mechanical seal oil chamber equipped with water protection elements, once overload and water will automatically cut off the power to protect the pump from damage. Installation of water level at the inlet control element, the pump can be automatically turned on, automatically shut down, without someone to run as required. Pump can easily achieve the overall lifting, testing, maintenance, without the machine pit of water to drain away the water without having to plug the machine pit and set the higher cost of the front brakes. Submersible pump components are anti-rust treatment, surface coating epoxy polyester rust, has a good anti-rust properties. QH type of use of premises drought submersible pump, drainage, flood control; municipal engineering; air defense system drainage; agricultural irrigation; rain and mild water; fire, nuclear power plant circulating cooling water supply and drainage; mining, shipyards, urban drainage; sewage treatment works.
