Ningbo and introduce axial flow pump manufacturer

Ningbo and introduce axial flow pump manufacturers, low flow pump is mainly applied to head, large flow, such as irrigation, drainage, drainage canal, ship lock water level control, or used as a power plant large circulating pump. Lift higher axial flow pump ( When necessary into two stage) For shallow water jet propulsion of the ship. As the main equipment of the rain, submersible pump station have QZB type submersible axial flow pump and QH ( B) Type diving mixed flow pump, is the motor with axial flow pump and the combination of mixed flow pump e-machine in one product, is a traditional long axis axial flow and mixed flow pump updated products. Main characteristics: simple construction, low engineering cost, convenient maintenance and management, operation simple and easy to automate work good reliability, beautify the environment and get rapid development. Second, the long axis of the submersible pump with the traditional pump in addition to using occasions, in and out of the water condition, characteristic parameters are basically consistent, also has the following significant advantages: save more than 30% of the pumping station project total investment; Construction cycle to save more than 40%; Installation time, saving more than 95%; The unit weight more than 50%; Save the investment pumping station of flood control wall; Low maintenance cost; No running noise, simple operation, easy to automated operation; Saves the ground building height is low, the pump room construction, even under the ground to build pumping stations. Axial flow and mixed flow pump, therefore, the old and new customers, can easily in the process of construction pumping station project in submersible pump replacement, can be in the old pumping station renovation project to update submersible pump, this pump is mainly suitable for the following occasions: farmland irrigation and drainage; Municipal emissions rain and mild sewage; In the industrial process water, cooling water; Water diversion project in the water. Submersible pump nominal diameter water from 350, 500, 600, 700, 800, 900, 1000, 1200, 1400, 1600, a total of 10 kinds of diameter, flow range 0. 12 - 2-12 m3 / s, lift range 14m； 7 power range. 5 - 630千瓦; 380 v, 660 v, 3 kv voltage level, 6 kv, 10 kv. Three, the structure to explain QZB type submersible axial flow pump and QH ( B) Diving mixed flow pump, water pump by the bell, the water impeller parts, impeller shell and guide vane body four parts. Submersible motor is fully sealed dry type asynchronous motor, chassis closed to motor, motor top cable wire have static sealing device, the motor end cover have a rotating shaft sealing device, under the submersible motor has all the diving operation safe and reliable performance. Of seal leakage, coil and bearing temperature rise are monitoring, alarm and protection, will not affect the normal operation of the motor (early leakage Only alarm) 。 When the coil temperature over 135 ℃, bearing temperature exceeds 90 ℃, using power-off protection, to monitor all protector consists of a submersible pump special protector, to ensure the safety of the submersible pump is used. The sensor output signal received by the submersible electric pump protector. The protector for each output signals, including the switch quantity or analog output a switch signals respectively, and show alarm flares on the protector.
