Embodiment Construction

[0028] A precision metering ceramic plunger injection pump of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Such as figure 1 , figure 2 , image 3 As shown, a precision metering ceramic plunger injection pump of the present invention includes a pump head 2, two one-way valves, a pump body, a driving mechanism and a control drive unit. The one-way valve passes through the upper valve seat and the lower valve seat. The thread on the valve cover is connected to the threaded hole in the pump head 2, and the pump head 2 is fastened to the drive shell 4 through the four through holes and the pump casing 3 through the inner hexagonal bolt; the motor base 5 is passed through the inner hexagonal bolt Fasten to the drive housing 4 through four through holes, and the drive motor 6 is fastened to the motor base 5 through four through holes through hexagon socket bolts; one end of the plunger core 15 in the pump body is con...

Abstract

The invention discloses a precision metering ceramic plunger liquid charge pump which structurally comprises a pump head, two single-direction valves, a pump body, a driving mechanism and a control driving unit. The singe-direction valves are connected into thread holes in the pump head through threads on upper valve bases and lower valve covers. The pump head penetrates through four through holes through inner hexagonal bolts, and the pump head and a pump body outer shell are fastened on a driving outer shell. A motor base is fastened on the driving outer shell by the fact that inner hexagonal bolts penetrate through four through holes. A driving motor is fastened on the motor base by the fact that inner hexagonal bolts penetrate through four through holes. One end of a plunger core in the pump body is connected with inner threads of a floating connector in the driving mechanism through outer threads. The driving mechanism is connected with the control driving unit. The liquid charge pump has corrosion resistance and abrasion resistance, impurities are not mixed into ceramic, so that the fact that medicine liquid is not contaminated during a liquid-charge process is guaranteed, the roughness of the surface of the ceramic is low, on-line washing is easy, and accuracy and speed are improved.

Description

technical field [0001] The invention relates to a liquid injection pump, in particular to a precise metering ceramic plunger liquid injection pump. Background technique [0002] Metering pumps, especially more sophisticated metering pumps, have been widely used in filling equipment in the fields of pharmaceuticals, biological reagents, and petrochemical industries due to their high-precision control of fluid metering and strong corrosion resistance. Existing metering pumps generally include three parts: drive motor, drive end and fluid end. The state can change the stroke speed and stroke length or the speed of the drive motor through the control parameters of the drive motor to achieve the purpose of changing the flow rate. The current metering pump has undergone continuous development and improvement, and has formed three mainstream product shapes of plunger, diaphragm and catheter peristalsis. The mature power drive method and liquid end material technology make the cur...
