Description
Technical field
The invention belongs to the mold injection technical fields of impeller, are related to a kind of injection mold of integral type closed impeller.
Background technique
The hydraulic centrifugal pump of impeller, pump case, control ball valve, motor and PCBA electric-control system composition mechanically or electrically, extensively
For civil water pump, automobile fuel pump and heat management system, be divided into two major classes by function: one kind is that trandfer fluid acts on, such as
Civil water heater, automobile fuel pump etc., fluid here are as consumables；Another kind of is temperature control set for adjusting, such as: the people
With air-conditioning heat pump, automobile cooling system pump, heat management system pump etc., these will not or seldom generate disappearing for fluid
Consumption mainly makes fluid generate ringing.
Such as in auto pump, impeller is mounted on pump seat or pump case, and the main line of pump case is connected by mounting base and the pump housing
It connects, motor impeller high speed rotation produces powerful centrifugal force, and liquid is got rid of after being drawn through the pump housing from the entrance of pump case
To casing outlet, respective service aisle or workplace are flowed to.
Such as in automotive temp regulation and control system, the fluid come out from casing outlet is finally collected, and by again
It is sucked into pump case and the pump housing from the nozzle of main line, unless obtaining the instruction of temperature or flow control system, driving is in work shape
Under state, fluid will be run by the mode of this fixation and direction in cycles, form a temperature scaling factor.
Traditional blade wheel structure is relatively easy or is open type；It is plane up and down, seriously affects fluid in this way
Mechanical property, power is small, and lift is short.
Summary of the invention
