Description
Technical field
The invention belongs to Quimby pump equipment technical fields, are specifically related to a kind of split type line with rubber Quimby pump.
Background technique
Quimby pump is with the different left-right rotary screw rod of a pair of of rotation direction and seal cartridge inner wall, in screw rod rotary course
In gradually build up seal chamber, and as screw rod operating seal chamber is continuously from the suction side of pump along axial passage to outlet side, thus
Realize transfer operation, i.e., the screw pump, which is formed by by the pump housing with screw rod, engages spatial volume variation and movement to convey liquid
Or it is allowed to be pressurized.When suction chamber one end screw rod engagement spatial volume be gradually increased, pressure reduction, liquid under differential pressure action into
Enter to engage spatial volume.As soon as liquid is in seal chamber continuously along axial direction when volume increases to maximum and formation seal chamber
Mobile, until discharge chamber one end, the screw rod engagement spatial volume that chamber one end is at this moment discharged is gradually reduced, so that liquid is discharged.Spiral shell
Bar pump has that pumped (conveying) medium is steady, release the low turbulent flow of medium, pressure fluctuation is faint, mechanical oscillation are small, low noise etc. is many excellent
Point.But structure is complex in screw pump and internal screw engagement space is smaller, therefore is not suitable for internal miscellaneous containing solid
On the one hand the conveying of matter medium is easy to cause the abrasion of transfer structure, reduce the transmission effect of subsequent medium, be on the other hand easy
