zw self-priming non-clogging sewage pump resolution

zw series of self-priming non-clogging sewage pump is a new product developed successfully on the basis of repeated research of similar technologies at home and abroad. The pump set self-absorption and non-clogging sewage in one, the use of axial reflux mixed outside, and through the pump body, impeller runner unique design, as the general self-priming pump does not need to install the bottom valve and irrigation water, But also suction row containing large particles of solid and long fiber impurities liquid can be widely used in municipal sewage projects, aquaculture, light industry, papermaking, textile, food, chemicals, electricity, fiber, slurry and mixed suspension and other chemical media Ideal impurity pump. Compared with similar domestic products, this pump has the features of simple structure, good self-absorption performance, strong sewage discharge capacity, high efficiency and energy saving, convenient use and maintenance and so on. It is a pioneer in domestic sewage pump products. Each of the top technical performance indicators leading the country, reaching the international advanced level, has a broad application market and development prospects. Product use zw series self-priming non-clogging sewage pump is suitable for the discharge of serious polluting wastewater from factories and factories, the sewage discharge station of the main house, the water supply system of urban sewage treatment plant, the drainage system of civil air defense system, the water supply equipment of waterworks, the hospital , Hotel sewage, municipal engineering construction sites, mining auxiliary machine, rural digesters, irrigation and other industries, conveyor belt particles of sewage, dirt, can also be used for water and with weak corrosive media. Use of 1, the ambient temperature of three 500C, medium temperature blue 80'C, special requirements up to 2000C. 2, medium PH value of cast iron material is 6.9, stainless steel is 2-13.3, heavy medium does not exceed 1240 kg / m304, self-priming height can not exceed the specified 4.5-5.5 meters, suction pipe length of 10 meters. 5, through the ability to suspend the particle diameter of 60% of the pump diameter, the fiber length of 5 times the pump diameter. Structure and working principle ZW series self-priming non-clogging sewage pump is mainly composed of pump body, impeller, back cover, mechanical seal, pump shaft, bearing seat, inlet valve, gas-liquid separation pipe, water inlet valve, Pump structure shown in Figure. The working principle of the pump: The pump body is provided with a liquid storage cavity, which is communicated with the pump working cavity through the upper return hole and the circulation hole below to form a pump axial return external mixed system. Pump stopped working, the pump cavity has a certain volume of liquid storage. When the pump starts, the pump liquid under the action of the impeller, the entrained air is thrown up, liquid through the gas-liquid separation tube grid back to the working chamber, the gas is discharged from the pump, the pump to form a certain Vacuum, to achieve the role of self-absorption. Pre-start preparation and operation 1, check the pump base, coupling, bearing and other connecting parts of the fasteners have loose? If loose should be tight. 2, the rotation of the coupling by hand if there are cassette tapes or other abnormal phenomenon? 3, open the pump above the water valve, add less than two-thirds of the reservoir water volume, close the valve. After boot without recharging. 4, connected to the power trial about, from the motor side, clockwise turn. (Do not reverse) 5, boot work, observe whether the normal pump operation If abnormal phenomena should be found out to be ruled out.
