Multichannel plunger pump and using method thereof

Abstract

The invention provides a multi-channel plunger pump and a using method thereof. The multi-channel plunger pump comprises a pump base unit and a pump head unit. A plurality of conical holes are formedin a locking plate, and the diameters of the conical holes are gradually increased from top to bottom. A locking claw component comprises an integrally-formed locking claw base and a plurality of locking claws located on the locking claw base. The locking claw base is fixed to a driving plate. The locking claws penetrate through driving plate holes, extend to the position above the driving plate and are inserted into the conical holes in the locking plate. The multi-channel plunger pump has the advantages that (1) the pump base unit and the pump head unit are of a split structure, and automatic locking and automatic separation of the pump base unit and the pump head unit are achieved through an automatic locking mechanism; (2) the function of automatically unloading a suction head is realized through a suction head unloading part; (3) the radial automatic aligning function of a plunger is realized through an elastic assembling mode of a plunger component; and (4) effective sealing of aplunger assembly is achieved through multiple sealing modes, and meanwhile the multi-channel plunger pump has the advantages of being good in sealing performance, long in service life, free of maintenance and the like.

Description

technical field [0001] The invention belongs to the technical field of plunger pumps, and in particular relates to a multi-channel plunger pump and a usage method thereof. Background technique [0002] A multi-channel plunger pump, such as a 96-channel plunger pump, is the core component of a large-capacity pipetting workstation. In the prior art, the pump head and the pump base of the multi-channel plunger pump are designed as an integral structure, resulting in a The following problems: (1) When the pump head or pump base fails, only the overall multi-channel plunger pump can be replaced, which has the problems of high replacement cost and low resource utilization; (2) When pump heads with different ranges are required , only the overall multi-channel plunger pump can be replaced, which also has the problems of high replacement cost and low resource utilization. Contents of the invention [0003] Aiming at the defects in the prior art, the present invention provides a m...
