Abstract

The present invention relates to a streaming potential online measuring instrument probe lower piston improved design, namely a new design of a probe lower piston. The new design of the invention includes an electrode, an electrode check ring, a lower piston boss, a check ring upper surface and an interval. The reason of the collision of the lower piston and the electrode, the electrode check ring (Figure 2) is that the interval between the lower piston and the electrode, the electrode check ring is too small, wherein the interval is defined by a streaming potential measurement principle and cannot be arbitrarily changed. In order to increase the interval without the streaming potential measurement principle broken, the diameter of a part of the lower piston that collides with the electrode and the electrode check ring (Figure 2) is needed to be decreased, such that the lower piston which performs up-and-down movement and back-and-forth swing simultaneously cannot contact with the electrode and the electrode check ring (Figure 2), and therefore, the collision of the lower piston and the electrode, the electrode check ring (Figure 2) can be avoided, and the service life of a probe can be prolonged.

Description

Streaming potential on-line measurement instrument probe lower piston improves

Technical field

The present invention relates to streaming potential on-line measurement instrument and improve design---probe lower piston newly designs.The present invention, by improving the lower piston design of streaming potential on-line measurement instrument probe, effectively extends the serviceable life of probe.

Background technology

Streaming potential on-line measurement instrument is real-time measurement apparatus, needs lower piston 40 move up and down continuously (referring to Fig. 2).Lower piston 40 has relative motion with probe measurement chamber 52, and very little apart from 42 between the two.Due to mechanical drive reason, lower piston is in moving up and down, with swing, clash into electrode 20 and back-up ring 24(Fig. 2 thereof), electrode 20 and back-up ring 24(Fig. 2 thereof) be with glue, itself and measuring chamber 52 to be bonded together, be subject to after continuous shock electrode 20 and back-up ring 24(Fig. 2 thereof) will throw off with measuring chamber, probe damages, and cannot measure.The present invention improves lower piston design, avoids lower piston to clash into electrode 20 and back-up ring 24(Fig. 2 thereof), extend the serviceable life of popping one's head in.

Summary of the invention

1, technical matters to be solved

There is following defect in current streaming potential on-line measurement instrument: when device busy, easily cause that lower piston clashes into electrode and back-up ring thereof, electrode and back-up ring thereof are subject to throwing off with measuring chamber after continuous shock, and probe damages, and causes device to measure.

2, technical scheme

In order to overcome the above problems, to the invention provides a kind of streaming potential on-line measurement instrument and improve design---probe lower piston newly designs, and comprising: on electrode 20, electrode back-up ring 24, lower piston boss 26, above back-up ring 62, spacing 42.Lower piston 40 and electrode 20 and back-up ring 24(Fig. 2 thereof) reason of clashing into is spacing 42 too little (setting of spacing is determined by streaming potential measuring principle, can not arbitrarily change) between the two.Do not destroy again streaming potential measuring principle in order to increase spacing 42 simultaneously, need to dwindle lower piston and electrode 20 and back-up ring 24(Fig. 2 thereof) shock diameter partly, make lower piston cannot touch electrode 20 and back-up ring 24(Fig. 2 thereof when (simultaneously with swing) moving up and down), thus avoid lower piston and electrode 20 and back-up ring 24(Fig. 2 thereof) shock.

3, beneficial effect

The present invention improves lower piston design, avoids lower piston to clash into electrode 20 and back-up ring 24(Fig. 2 thereof), extend the serviceable life of popping one's head in.

Embodiment

Below by embodiment, the present invention is described in detail.

Embodiment 1

Its working method is as follows:

Fig. 2 draws the improvement design of lower piston, in the time that lower piston 40 moves upward to peak, its boss 26 with above back-up ring 62 on par line; In the time that lower piston 40 moves downward minimum point, it is enough large that the spacing 42 of itself and electrode 20 and back-up ring 24 thereof becomes, and makes lower piston 40 can not touch electrode 20 and back-up ring 24 thereof, thereby avoid mutual shock.
