Embodiment Construction

[0058] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0059] Such as figure 1 As shown, the principle of interconnection of the positive displacement metering pump 1 in the working position with the drive machine 2 is illustrated. The drive machine 2 comprises two arms, a second arm 6 and a first arm 7 , and a stationary body 8 . A positive displacement metering pump 1 comprises a hollow cylindrical pump body 3, a fluid inlet 12 and a fluid outlet 13, wherein a piston 4 is slidably mounted in the hollow cylindrical pump body 3 along the pump axis AA' and rotates around the pump axis AA' A switching valve 5 is installed. The piston 4 and the switching valve 5 are generally cylindrical matched with the inside of the pump body 3 . The piston 4 and the switching valve 5 protrude from one side of the pump body 3 respectively. The sleeve 10 protrudes from the side of the pump body 3 .

Abstract

The invention relates to the technical field of positive displacement metering pump installation, and provides a method for installing a positive displacement metering pump at a working position. Thepositive displacement metering pump comprises a pump body. A piston device is slidably mounted in the pump body, and a switching device is rotatably mounted in the pump body. Both the piston device and the switching device extend out of the pump body. Firstly, the piston device and the switching device are fixed to the pump body; Then any one of the pump body, the piston device and the switching device is hooked to a fulcrum P; finally, the volumetric metering pump is rotated around the fulcrum P to fix the other two of the pump body, the piston device and the switching device to the working support. The invention also relates to the assembly of such a pump with a drive machine comprising a stationary body and a first arm for sliding movement in the machine axis BB' direction. The piston device and the pump body are respectively fixed on the first arm and the static body through special shape matching. The positive displacement metering pump can be safely and rapidly fixed to a corresponding machine.

Description

technical field [0001] The invention relates to the technical field of displacement pump installation, in particular to a method for installing a displacement pump on a mechanical device in a restricted area where an operator has limited access. Background technique [0002] Industries such as food and pharmaceuticals use positive displacement or positive displacement pumps to fill individual containers with liquid preparations, such as injecting pharmaceutical preparations into syringes (vaccines), solutions into IV bags for intravenous injection, pasteurized solutions into The bottle is medium. Among other things, it is critical that liquid formulations remain pure, sterile and volume-dispensed with high accuracy. [0003] For these purposes, high precision positive displacement pumps are developed in various materials such as stainless steel or even ceramics to avoid any metal contamination. [0004] Such pumps are generally manufactured around a main central axis defin...
