Abstract

A full-automatic strong self-priming centrifugal pump relates to the technical field of centrifugal pump manufacturing and comprises a centrifugal pump body. A centrifugal pump body control system is connected onto the centrifugal pump body, and a priming system is arranged at an inlet end of the centrifugal pump body in a connected manner. The centrifugal pump with the self-priming system omits water filling when starting, omits a bottom valve, can reach the highest priming height of eight meters, and is short in priming time.

Description

Full-automatic strong self-sucking centrifugal pump
Technical field
The utility model relates to a kind of manufacturing technology field of centrifugal pump.
Background technique
Before the each work of existing centrifugal pump, all need manually filling water in the pump, with air in the blowdown pump, could proper functioning, so both to have wasted and worked, its working efficiency is also lower.

The utility model has self-suction system, need not pour water during startup, and without bottom valve, suction head reaches as high as 8 meters, and self-priming time is short, and flow is with 100~3600m 3/ h, self-priming time are 10~30 seconds; Reduced engineering cost, avoided because of there being self-absorption function need not build underground pump house because of the corrosion phenomenon of underground pump house humidity to motor and electrical equipment.
Self-suction system described in the utility model comprises body, one-way valve, sucking pipe, floating chamber's body, be connected with the self-priming apparatus of self-priming apparatus control system, described body is connected the feed-water end of described centrifugal pump main body, one opening tributary pipe up is set on described body, described floating chamber body is connected the top of described tributary pipe, outlet end at described floating chamber body connects sucking pipe, the other end at described sucking pipe connects self-priming apparatus, on the sucking pipe between described floating chamber body and the self-priming apparatus, be connected one-way valve, the vacuum pressure gauge with electric contact is set between described one-way valve and self-priming apparatus, and the signal output part of described vacuum pressure gauge with electric contact is connected on the control system of self-priming apparatus and centrifugal pump main body.
When self-suction system of the present utility model is worked, by strong self-suction device the air in intake pipe and the pump is got rid of, made stroke vacuum in the pump, after water is drawn up, water can enter strong self-suction device through pipeline, but the existence of floating chamber's body and one-way valve has avoided water to enter strong self-suction device; The vacuum pressure gauge with electric contact can be connected with electric control box, realizes self-suction system and main pump interlocking, by pressure vacuum gauge vacuum values is set, and after degree of vacuum reached vacuum values, the vacuum system automatic stop was forwarded to main pump work automatically.
Floating chamber described in the utility model body comprises housing, ball float, sealing plate, described ball float is arranged in the housing, upper end at described housing is provided with loam cake, in the connection of the lower end of described housing one sieve plate is set, center at described loam cake is provided with through hole, in the upper end of described ball float guide rod is set, described upper end of going up guide rod is arranged in the described through hole, middle part on described on the guide rod fixedly installs sealing plate, described sealing plate cooperates with through hole to be arranged, in the connection of the lower end of described ball float guide rod down is set, the described lower end of guide rod down is set in the middle part of described sieve plate, fixedly installs balancing weight on the described top of guide rod down.
Floating chamber of the present utility model body, self-suction system bleed reach vacuum after, be used for stoping water to enter strong self-suction device, after water enters floating chamber's body, ball float come-up in floating chamber's body, sealing plate on the last guide rod also floats under the drive of ball float, and sealing plate is sealed the through hole of loam cake, and water just can not enter strong self-suction device like this.
Self-priming apparatus described in the utility model is a vacuum pumping device.By vacuumizing, negative pressure makes water enter in the pump, treat that water is full of after, centrifugal pump just can normal operation.
