Problems solved by technology

However, in the prior art zirconia gel preparation method, the colloid is not uniformly dried during drying, and the colloid structure is easily destroyed, resulting in cracking and structural shedding of the ceramic plunger rod prepared by calcining, which is not conducive to the ceramic plunger. The rod is connected with the water injection pump, reducing the production efficiency of the water injection pump

Embodiment Construction

[0032] Such as Figure 1 to Figure 7 Shown, be the gel preparation method of a kind of gel forming zirconia ceramic plunger rod of the present invention, comprise the steps:

[0033] (a) Hydroxide-forming sol: first adjust the pH of the aqueous solution, then boil the zirconium salt solution at 120°C for 20-30 hours, and precipitate to obtain Zr(OH) 4 Colloid, then Zr(OH) 4 Colloids are aged.

[0034] (b) Gel preparation: first weld the baffle 2 at the notch of the gel shell 1, and set the slope of the baffle 2 inside the notch. Put swing arm 3 at the notch place again, penetrate rotating rod 4 at the notch place simultaneously, swing arm 3 is arranged on the rotating rod 4 one by one. Then swing arm 3 is adjusted and fixed one by one from left to right, swing arm 3 is rotated on turning bar 4, swing arm 3 keeps vertical state, and the briquetting block 15 of swing arm 3 bottom is against the slope of baffle plate 2. Then buckle the buckle 6 into the draw-in groove 5 of th...

Abstract

The invention discloses a gel moulding zirconia ceramic plunger rod gel preparation method. The method comprises the following steps: a) formation of a hydroxide sol; b) gel preparation; c) primary drying of a gel; d) colloid collection; e) secondary drying of the gel; f) re-collection of the colloid; and g) moulding and calcining of a zirconia ceramic plunger rod. The method is capable of uniformly drying the colloid, can reduce the destroy on colloid tissue structure, reduces the cracking and structural shedding phenomena of the calcimined ceramic plunger rod, increases the preparation quality of the ceramic plunger rod, is in favor of connection of the ceramic plunger rod and a water injection pump, and increases the production efficiency of the water injection pump.

Description

technical field [0001] The invention belongs to the technical field of preparation of zirconia ceramic plunger rods, and in particular relates to a gel preparation method for gel forming zirconia ceramic plunger rods. Background technique [0002] Along with the development of my country's social economy, the development of my country's oil mining industry has also been promoted accordingly. In the actual mining process, in order to further improve efficiency, water injection pumps are needed. For the water injection pump, the choice of the plunger will directly affect the working efficiency of the water injection pump. In terms of the performance of the plunger, the performance of the ceramic plunger rod is better than that of the metal plunger rod. [0003] At present, ceramic plunger rods are mainly prepared by zirconia gel, which is mainly to hydrolyze and polycondense zirconium salt solution to form Zr(OH) 4 The stable sol of colloidal particles is dried, dehydrated an...
