Production of ZJE/ZJW filter press feed pump centrifugal pump

1Detailed description of filter press centrifugal pumpZJE/ZJW filter press feed pump

The ZJE type filter press feed pump adopts a hydraulic design and impeller installation method, ensuring that its performance curve is steeper than that of a general impurity pump. It is very suitable for achieving high flow, low-pressure feeding and low flow, high-pressure filtration with changes in resistance during filter press feeding. Its special hydraulic performance perfectly matches the gradual process of the filter press from cavity to filling and then to drying. During the initial feeding stage, there is no need to control the motor overload caused by excessive flow rate without valves. At the same time, low pressure will not have an impact on the filter plate frame, reducing the damage of the filter cloth on the filter plate frame and not causing vibration to the filter plate. The small flow rate and high pressure in the later stage of pressure filtration are less likely to cause pump blockage. Especially during the later pressing period, the installation method of the impeller and the role of the secondary impeller of the pump under high pressure ensure that there is basically no leakage at the shaft seal.

The ZJE type filter press feed pump produced by our company is designed and developed by our company and the Fluid Machinery Research Institute of Jiangsu University of Science and Technology based on the feeding conditions of various filter press usage scenariosFilter press feed pumpProduct.

After various trials in coal washing, environmental protection, aluminum plants, smelting and other occasions, its performance has reached a high level in China. Once it is put into the market, its pressure filtration effect, filtration drying time, anti clogging of sewage and pollutants, no leakage, and overall stability have been highly praised by users. It has played a positive role in improving the efficiency of production processes for various users.

IIAdvantages of double impeller filter press pumpZJE/ZJW filter press feed pumpA two-stage pump is named after the structure of the pump, consisting of two impellers and two pump casings, which is equivalent to two single-stage pumps connected in series. However, the conveying effect is different from that of two single-stage pumps connected in series, and the operating conditions are also different.
The two impellers of a two-stage pump are installed on the same shaft and rotate together. During operation, the output of one impeller enters the input of the second impeller. The flow rate does not increase compared to a single-stage pump, but the pressure is the superposition of the impellers at all stages. The filter press is a device that separates moisture by pressing materials under high pressure, so the high pressure output of the two-stage pump is very suitable for the feeding requirements of the filter press.
After further design improvements, the two-stage pump specifically designed for feeding the filter press can not only provide high pressure, but also change the flow rate and pressure with the operation of the filter press. In the early stage, high flow rate and low pressure, and in the later stage, high pressure and small flow rate are more suitable for the working conditions of the filter press. Single stage pumps are far from achieving this effect.
