Problems solved by technology

[0003] However, the electromagnetic diaphragm metering pumps currently on the market can only transport the liquid in one direction, and cannot back pump the liquid, which will cause those strong corrosive liquids to remain in the pump for a long time, thereby destroying the structure of the pump body and affecting the life of the pump body; In addition, this kind of pump is not accurate for the control of small liquid flow.

Embodiment Construction

[0024] The preferred embodiments of the present invention will be described in further detail in conjunction with the accompanying drawings.

[0025] Such as Figure 1-7 The precision diaphragm pump includes a PLC controller, a machine base 1, a drive assembly 2, an upper push-pull magnetic coil 3, a lower push-pull magnetic coil 4, a sealing assembly 5, and a lower liquid channel 6 and an upper liquid channel 7, controlled by PLC The device respectively controls the upper push-pull magnetic coil 3, the lower push-pull magnetic coil 4 and the drive assembly 2, and controls the upper push-pull magnetic coil 3 or the lower push-pull magnetic coil 4 to be energized or de-energized respectively, so that the drive assembly 2 and the sealing assembly 5 are movably coordinated. , used to control liquid input or output. It is prior art that the PLC controller controls each component, and the present invention does not describe in detail, and the lower liquid passage 6 and the upper l...

Abstract

The invention primarily discloses a precise diaphragm pump. The technical scheme is as follows: the precise diaphragm pump comprises a PLC, a base, a driving assembly, an upper push-and-pull magneticring, a lower upper push-and-pull magnetic ring, a sealing assembly, a lower liquid channel and an upper liquid channel. The PLC controls the upper push-and-pull magnetic ring, the lower upper push-and-pull magnetic ring and the driving assembly separately. By controlling the upper push-and-pull magnetic ring or the lower upper push-and-pull magnetic ring to gain or loss electricity, separately, the driving assembly and the sealing assembly are movably matched for controlling liquid input or output. By controlling the outflow velocity of a liquid by controlling the rotating speed of a steppingmotor, the feeding amount of the liquid can be regulated, so that controllability can be seen precisely and positive and reverse flow directions of the liquid can be changed smoothly, too.

Description

technical field [0001] The invention relates to the technical field of pumps, in particular to a precision diaphragm pump. Background technique [0002] At present, electromagnetic diaphragm pump is the most common pump for transporting strong acid and strong alkali liquid. Electromagnetic diaphragm pump is a kind of metering pump. Metering pump is a special positive displacement pump that can meter the fluid to be transported. The main part is the driving part, the diaphragm metering pump, the metering pump pumps the liquid from the medicine box into the system through the movement of the diaphragm, and the tool for conveying the liquid. When the plunger in the pump reciprocates each time, the volume of the liquid conveyed is fixed, so that Realize the measurement function. [0003] However, the electromagnetic diaphragm metering pumps currently on the market can only transport the liquid in one direction, and cannot back pump the liquid, which will cause those strong corr...
