The Design Of Cip Return Pump Is Mainly Based On Market Demand
The self-priming sewage pump designed by CIP Return Pump is mainly aimed at market demand. Simply put, it is a result of a certain market survey and summary, and is closer to market demand. The CIP return pump can be like a general clean water self-priming pump without installing a bottom valve or filling water. It can also pump dirt, sediment, waste mine impurities, feces treatment and all engineering sewage and colloidal liquids with a diameter of 60 times the outlet diameter and a fiber length of 1.5 times the impeller diameter, completely reducing the labor intensity of manpower, and it is easy to install and use, with very little maintenance. The performance has reached the international advanced level and has a broad application market and development prospects.
The CIP return pump has a unique hydraulic design. The impeller is retracted in a separate impeller chamber, and the impeller chamber is connected to the pressure chamber. When the impeller rotates, the liquid in the pump produces a strong axial vortex effect, which creates a vacuum at the inlet and a head at the outlet. Therefore, impurities can be discharged from the pressure chamber, so its flow channel is completely unobstructed, and its sewage discharge effect is unmatched by other CIP return pumps.
Determination of the volume of the gas-liquid separation chamber and the outlet height of the CIP reflux pump Gas-liquid separation refers to the part of the pump body outside the extrusion chamber. The larger its volume, the better the gas-liquid separation effect and the faster the separation. However, when the volume of the gas-liquid separation chamber reaches a certain level, the effect of further increase is not significant, and on the contrary, the pump body will be bulky. Therefore, there is an optimal volume value for the gas-liquid separation chamber. According to existing experience, its value is equal to or slightly greater than the liquid storage volume. Under the condition of ensuring the volume of the gas-liquid separation chamber, the height from the pump body outlet to the impeller centerline can be determined when drawing according to the liquid storage volume and the volume of the gas-liquid separation chamber.
The CIP reflux pump is designed as a two-phase flow impeller with a wide outlet. Therefore, two sets of impellers can be configured for the same volute. A three-dimensional flow impeller is used for clear water, and the impeller is designed using Cai's two-phase flow theory for two-phase flow, which not only guarantees the design performance parameter table of the pump, but also guarantees the efficiency and corrosion resistance of the pump. Especially when used in equipment supporting the main engine, the CIP return pump can better reflect the superiority of the main engine, improve the overall performance of the main engine equipment, and enhance the external image of the main engine. The only difference is that the return water does not flow to the outer edge of the impeller, but to the impeller inlet. When starting the internal mixing self-priming pump, the return valve at the front and bottom of the impeller must be opened to allow the liquid in the pump to flow back to the impeller inlet. Under the action of the high-speed rotation of the impeller, the water mixes with the air from the suction pipe to form an air-water mixture and is discharged to the separation chamber. Here the air is discharged and the water returns to the impeller inlet from the return valve. This is repeated until the air is exhausted and the water is sucked up.
The CIP return pump is a new type of pump that combines self-priming and sewage discharge. There is no need to install a bottom valve, no need to fill water, and it can also pump large solid particles, completely reducing the labor intensity of manpower, and it is easy to install and use, with very little maintenance.
