ZJ series slurry pump often appear problems
- 1.The selection of the pump is too large, and the flow and head are larger than the actual condition due to improper selection of the coefficient. This situation makes the pump in the operation process, cavitation phenomenon, resulting in premature damage of the pump flow parts under the combined action of cavitation and abrasion, in the case of serious cavitation, the pump will produce vibration and noise, and even lead to a sharp decline in the flow, head and efficiency of the pump can not run; In addition, the pump in the operation of large flow, will also cause motor overload, heat, serious will burn the motor.
- 2. The pump selection is too small, the pump can not reach the user's required working conditions or process pressure, affecting the user's entire production effect or the overflow of the feed pool: in addition, the pump runs under a small flow rate for a long time, and the shaft may be broken.
- 3. The speed of the pump is too high, in the metallurgical industry or heavy medium coal preparation containing large particles, the speed is too high, which will greatly shorten the service life of the pump flow parts, cause the user to increase the cost, on-site maintenance frequency and other problems.
- 4. The average flow rate of the pipeline is too low, and the average flow rate of the pipeline is lower than the critical settlement deceleration, resulting in pipeline blockage and unable to transport slurry normally. Through the above examples, it can be seen that the selection of ZJ series slurry pump is more complicated, and if any link makes a mistake, it may lead to the mistake of the entire selection, causing irreparable losses to users, and having an adverse impact on their reputation. Therefore, in the selection, we must pay attention to the values of several key coefficients and calculate them carefully to achieve accuracy, so that the ZJ series slurry pump can fully reflect its advantages in field application.
