The device has high forming precision, and is convenient to be assembled, processed and produced, and greatly improves the production efficiency and manufacturing precision, and greatly improves the efficiency of the water pump and saves the energy consumption.
Description
Technical field
The utility model relates to a kind of water pump diversion disk.
Background technique
At present, general water pump both domestic and external, the blade of its diversion disk adopts the monolithic moulding mostly, with the front and rear cover plate welding, forms diversion disk again.Be manufactured with following shortcoming like this:
1. blade needs to adopt corresponding tool locating when welding, and when not only useless, and Location accuracy is poor.
2. the thermal stress that produces when welding makes deformable blade, has changed the design accuracy of original expection after the distortion.
3. the burr that produces when welding makes runner become rough.
Summary of the invention
The purpose of this utility model provides a kind of water pump diversion disk, and this device formed precision height is convenient to assembling and processing, can enhance productivity greatly and accuracy of manufacturing, and pump efficiency is increased substantially, and reaches energy-efficient effect.
The technical solution of the utility model is achieved in that it comprises disk, guide plate, black box, stator and stator cover plate, it is characterized in that: described disc shaft edge part to the inside is provided with and is used to change the guide plate that throws away the flow direction of fluid from the impeller channel outer rim, described disc shaft middle part to the inside is provided with black box, described disc shaft is provided with stator laterally, the described stator outside is provided with cover plate, and described stator is made of single stamping part.
The utility model has the advantages that reasonable in design, structure is unique, there is not distortion in the formed precision height when welding, can not produce burr yet, frock is easy, component are still less enhanced productivity and accuracy of manufacturing greatly, and the entrance edge of blade of global formation becomes thinner (only 0.5 millimeter), after the inlet side attenuation, suction performance and anti-cavitation performance also are improved.
