Core Tip: ZW self-priming non-blocking sewage pump is a novel structure developed on the basis of repeated research on similar technologies at home and abroad. The ZW self-priming sewage pump integrates self-priming and non-blocking sewage discharge, adopts axial recirculation and external mixing, and has a unique design through the pump body and impeller flow passage.
First, ZW self-priming sewage pump overview:
ZW self-priming non-blocking sewage pump is a novel structure developed on the basis of repeated research on similar technologies at home and abroad. ZW self-priming sewage pump integrates self-priming and non-blocking sewage discharge. It adopts axial recirculation and external mixing, and through the unique design of pump body and impeller flow channel, it can be installed like the general self-priming pump without installing the bottom valve. It can be used for municipal sewage treatment projects, river pond culture, light industry, papermaking, textile, food, chemical industry, electrical industry, fiber, slurry and mixed suspension, etc. by pumping water and absorbing liquids containing large particle solids and long fiber impurities. The most ideal impurity pump for chemical media. Compared with domestic similar products, ZW self-priming sewage pump has the characteristics of simple structure, good self-priming performance, strong sewage discharge capacity, high efficiency and energy saving, convenient use and maintenance, etc. The first. The technical performance indicators are leading domestically, reaching the international advanced level, with broad application market and development prospects.
Second, ZW self-priming sewage pump use range:
Compared with domestic similar products, ZW self-priming non-blocking sewage pump has the characteristics of simple structure, good self-priming performance, strong sewage discharge capacity, high efficiency and energy saving, convenient use and maintenance, etc. It is the first in the domestic sewage pump series. The technical performance indicators are leading domestically, reaching the international advanced level, with broad application market and development prospects. 1 Ambient temperature ≤ 45 ° C, medium temperature ≤ 60 ° C. 2. The medium PH value of the cast iron pump is 6-9, and the stainless steel pump is 1~14. 3. The maximum diameter of the particles is 60% of the pump diameter, and the fiber length is 5 times of the diameter. 4. The total weight of impurities in the medium does not exceed 15% of the total weight of the medium, and the specific gravity of the medium does not exceed 1240 kg/m3.
Third, the seal wear replacement:
1. Is the inspection base level before installation?
2. Check if all parts are damaged during transportation?
3. The pump itself is not allowed to be supported as a pipeline?
4. The pump and piping should be well sealed. Check if the fasteners on the pump base, coupling, bearing, etc. are loose? If it is loose, it should be fastened.
â—†Is there any jam or noise in the coupling by hand?
â—† Open the watering valve above the pump, add the reservoir water not less than two-thirds of the pump volume, and close the valve. There is no need to re-inject water after starting up.
â—† Connect the power supply and try to turn it. Seen from the motor end, it is turned clockwise. (reverse rotation is strictly prohibited)
â—† Start work, observe whether the operation is normal? If there is an abnormal phenomenon, the cause should be found and excluded.
