Description

Technical Field

[0001] The invention belongs to the technical field of ceramic pumps, and in particular relates to a wear-resistant and corrosion-resistant ceramic pump. Background Art

[0002] Ceramic plunger pump is a pump used for high-pressure fluid transportation. It uses a plunger made of ceramic material as a key component. It has excellent wear resistance, corrosion resistance and a long service life. Ceramic plunger pumps are widely used in industries that require high pressure, corrosion resistance and wear resistance, such as petrochemical, metallurgy, mining, coatings, food and other industries.

[0003] The working principle of the ceramic plunger pump is similar to that of a general plunger pump, which mainly relies on the reciprocating motion of the plunger to achieve the suction and discharge of liquid.

[0004] Although ceramic pumps have good wear resistance, if large particles exist in the transported liquid for a long time, it will still cause wear of the plunger and pump barrel. As the pump runs, the filter component at the liquid inlet will gradually become blocked, causing the filtration rate of the filter component to decrease and the resistance to plunger movement to increase.

[0027] S1, prompting the output end of the linear motion part to be inserted into the slot;

[0028] S2. The output end of the linear moving part is inserted into the slot. At this time, the motor drives the flat gear to rotate, and the flat gear pushes the filter plate B to slide along the filter plate A, thereby adjusting the area of ​​the filter holes formed by the filter holes A and B, so that the equivalent diameter of the particles of the debris entering the pump barrel is within the particle diameter threshold.

[0029] The present invention provides a wear-resistant and corrosion-resistant ceramic pump, which has the following beneficial effects compared with the prior art:

[0030] 1. In the present invention, if the lifting force information of the pump rod exceeds the lifting force threshold, it indicates that there is a risk of clogging in the filter plate assembly. At this time, the motor drives the crown gear A to rotate forward, and the crown gear A drives the crown gear B to drive the reciprocating screw to perform linear reciprocating motion. At this time, the reciprocating screw drives the filter plate A to vibrate, and the debris on the filter plate A is shaken off. After the preset vibration time, the motor drives the crown gear A to reverse, and the crown gear A drives the crown gear B to drive the reciprocating screw to rotate. The reciprocating screw drives the disc-shaped scraper frame threadedly connected thereto to perform linear motion along the sliding groove, scraping the inside of the Y-shaped liquid inlet pipe, and then pushing the debris shaken off or filtered by the filter plate A to the sewage outlet provided on the Y-shaped liquid inlet pipe, and then discharged from the sewage outlet, thereby improving the filtration rate of the filter plate assembly;

[0031] 2. In the present invention, when the average value information of the particle equivalent diameter of the debris particles obtained by the laser particle size analyzer at regular intervals within a cycle exceeds the particle diameter threshold, the output end of the linear motion part is inserted into the slot, and at the same time, the crown gear A drives the crown gear B to drive the reciprocating screw to rotate, and the reciprocating screw drives the flat gear to rotate, and the flat gear drives the filter plate B to slide along the filter plate A, thereby adjusting the area of ​​the filter hole formed by the filter hole A and the filter hole B, so that the equivalent diameter of the debris particles entering the pump barrel is within the particle diameter threshold, so as to prevent excessively large debris particles from entering the pump barrel, causing damage to the pump barrel and the pump rod, and affecting the service life of the pump barrel and the pump rod;

[0032] 3. The present invention can construct an evaluation model and output an evaluation coefficient based on the mean downward thrust information of the pump rod within a cycle, the mean equivalent diameter information of the particles within a cycle, and the movement speed information of the pump barrel, and then adjust the movement speed of the pump rod or the filter hole size of the filter plate assembly to evaluate the degree of wear of the pump barrel and the pump rod and take corresponding measures.

The laser particle size analyzer located at the outlet of the Y-shaped liquid outlet pipe 6 is used to detect the particle size in the liquid flowing out of the pump barrel 201, and the particle equivalent diameter information of the particles contained in the liquid in the pump barrel 201 is obtained. The downward thrust information and lifting force information of the pump rod 202 are obtained through the support plate A302. If When the lifting force information of the pump rod 202 exceeds the lifting force threshold, it indicates that the filter plate assembly 803 is at risk of being blocked. At this time, the motor 8042 drives the crown gear A8043 to rotate forward, and the crown gear A8043 drives the crown gear B8045 to drive the reciprocating screw 801 to perform linear reciprocating motion. At this time, the reciprocating screw 801 drives the filter plate A8031 to vibrate, and the debris on the filter plate A8031 is shaken off.

When the particle equivalent diameter mean value information of the debris particles regularly obtained by the laser particle size analyzer within the cycle exceeds the particle diameter threshold, the output end of the linear motion member 8063 is inserted into the slot 8064, and at the same time, the crown gear A8043 drives The crown gear B8045 pushes the reciprocating screw 801 to rotate, the reciprocating screw 801 drives the flat gear 8062 to rotate, and the flat gear 8062 pushes the filter plate B8032 to slide along the filter plate A8031, thereby adjusting the area of ​​the filter holes formed by the filter holes A8033 and the filter holes B8034, so that the equivalent diameter of the particles of debris entering the pump barrel 201 is within the particle diameter threshold, so as to prevent excessively large debris particles from entering the pump barrel 201, causing damage to the pump barrel 201 and the pump rod 202, and affecting the service life of the pump barrel 201 and the pump rod 202.

[0056] It also includes a system for evaluating the degree of wear of the pump barrel 201 and the pump rod 202. The evaluation system includes an information acquisition unit, a coefficient output unit and a control unit. The acquisition unit acquires the mean downward thrust information of the pump rod 202 within a period, the mean particle equivalent diameter information within a period and the movement speed information of the pump barrel 201, and imports the acquired mean downward thrust information, the mean particle equivalent diameter information within a period and the movement speed information into the evaluation model in the coefficient output unit after being processed by the amountless steel, and then outputs the evaluation coefficient and compares it with the evaluation coefficient threshold. If the evaluation coefficient is not within the evaluation coefficient threshold, control information is formed. The control unit receives the control information and first adjusts the movement speed of the pump rod 202. If the evaluation coefficient is still not within the evaluation coefficient threshold after the speed of the pump rod 202 is adjusted, the filter hole size of the filter plate assembly 803 is adjusted to make the evaluation coefficient within the evaluation coefficient threshold. The evaluation model is expressed as:

[0057] PG(V,K,F)=VT((V1-δV) 2 +(K1-δK) 2 +(F1-δF) 2 ) -1

[0058]
