The stability of pump operation, in the case where ensuring that efficiency is constant, the diameter of outlet discharge particle is improved, realizes high concentration paper
The discharge of slurry, pump housing front side selection open type structure, convenient maintenance.Mechanical seal will not be started using machine for the assembly of unit load seal structure
When the problems such as leaking, and simple installation.Pump cover is positioned using bolt, can effectively prevent the generation of machinery de- phenomena such as damaging,
And quick detachable, convenient maintenance.
Beneficial effect：For the utility model for traditional pulp pump, impeller uses half-opened impeller, can be more preferable
The discharge for realizing paper pulp, impeller is in the diffusion on wheel disc, being more beneficial for paper pulp by multiple upright blades, improves work effect
Rate, manufacturing cost is low, and effect is good, and impeller is coordinated with pump shaft using cone stone, is added tight ness rating, is improved the stabilization of pump operation
Property.Machine internal blocking is not easily caused, and pump cover is detachable, and convenient inside is repaired and cleared up, the installation letter of machine for the assembly of unit load seal structure
Just, being capable of more effective prevent leakage.Production efficiency is improved, reduces the production time, makes operation simpler using advanced
3D printing increases material manufacturing technology, model pump is researched and developed, and the reliability tests such as vibrating noise are carried out to it, ensure the reasonable of structure
Property, solve the problems, such as product reliability；Product fills the domestic gaps, substitutes import.Using advanced 3D printing increasing material manufacturing method,
The R＆D cycle is reduced, saves R＆D costs, impeller, stator and the volute structure finished to design is directly tested to test
Demonstrate,prove design result.Indices, such as tolerance fit, vibration frequency, Oscillation Amplitude, choma leakage are confirmed before product formally produces
Amount etc., convenient further improvement and the extensive manufacture of product, while reduce the manufacturing, it is likely to occur in running
Problem, ensure product quality.
