ZW type horizontal self-priming pump without blocking offers Self-priming sewage pump product overview:
ZW non blocking horizontal self-priming sewage pump is a new structure developed based on similar products at home and abroad study repeatedly on the technology of new products, the pump self-priming function and non clogging sewage in one, the axial circumfluence form, and through the pump body, the unique design of the impeller, can be like the general self suction water pump do not need to install the valve and irrigation water, and suction with large particles and long fiber solid impurities unwrapping. Widely used in municipal sewage works, pond aquaculture waste treatment, waste precipitation of impurities, impurity pump light industry, papermaking, food, chemical, pharmaceutical, power, and other chemical slurry mixture to the medium quality.
ZW type self-priming sewage pump compared with the domestic similar products, has the advantages of simple structure, good self-priming performance, (self-priming height up to 5M), sewage capability, high efficiency and energy saving, convenient maintenance, the sewage pump series products of ZW type self-priming sewage pump is a domestic initiative. The indicators in the domestic leading to reach the international advanced level. Has a broad application market development prospects.
ZW - type horizontal self-priming pump without blocking type meaning:
ZW - type horizontal self-priming pump without blocking offers Self-priming sewage pump working principle:
ZW type self-priming sewage pump, mainly by the pump body, impeller, pump cover, mechanical seal, shaft, bearing seat, inlet valve, gas-liquid separation tube, water valve, inlet and exhaust pipe etc.. The pump structure is shown in figure.
ZW self priming sewage pump works: the pump body is provided with a liquid storage chamber, and through the top of the reflux hole and the bottom of the circulation hole and the pump working chamber is communicated, constitute the pump axial plus flow outside the mixed system. After the pump stops working, the pump cavity has a certain volume of liquid storage. When the pump starts, the relevant authorities in the liquid in the impeller under the action of air entrainment is thrown upwards, the liquid separating tube grid reflux into the working cavity through the gas, gas is discharged out of the pump, the pump to form a vacuum, achieve self absorption effect.
ZW - type horizontal self-priming pump without blocking offers Self-priming sewage pump structure:
ZW - type horizontal self-priming pump without blocking offers Self-priming sewage pump products use conditions:
1, the ambient temperature is less than or equal to 50 DEG C, the special requirements of medium temperature are less than 80 to 200 degrees
2, medium pH value of cast iron material for the 6--9, stainless steel for 2-13.
3, medium severe no more than 1240 kg /m3.
4, ZW type self-priming sewage pump self-priming height can not exceed the specified value of 4.5-5.5 meters, the suction pipe length is less than or equal to 10 meters.
5, ZW type self priming sewage pump through the capacity of suspended particles diameter of 60% of the diameter of the pump, fiber length of 5 times the diameter of the pump.
ZW - type horizontal self-priming pump without blocking offers Self-priming sewage pump product features:
1, ZW type self-priming sewage pump with double blade impeller structure, greatly improving the ability through the dirt
2, ZW type self-priming sewage pump mechanical seal using a new type of friction pair, and long into the oil chamber operation;
3, the whole structure is compact, the volume is small, the noise is small, the energy saving effect is remarkable, the maintenance is convenient, and the user is convenient to change;
4, automatic control cabinet can be based on the required liquefaction changes, automatic control of the pump and the end of the stop, no special care, the use of very convenient;
5, according to the user needs to be equipped with installation, it is to the installation, maintenance of the arrival of great convenience, people do not have to enter the sewage pit;
6, can be used in the design, and ensure that the motor will not overload;
7, ZW type self-priming sewage pump with outdoor motor without pump room, can be installed directly and save money for outdoor use.
ZW - type horizontal self-priming pump without blocking offers Self-priming sewage pump product use:
ZW type horizontal self-priming pump without blocking suitable for factory commercialheavily pollutedwaste water, the main residential area of the sewage station, city sewage treatment plant to send water system, air defense system drainage station, tap water plant water supply equipment, hotel, hospital sewage, municipal engineering construction sites, mines completewithmachine, rural biogas pool, irrigation and other industries, sewage containing particles, dirt, can also be used to clean water and weak corrosive medium.
ZW - type horizontal self-priming pump without blocking offers Self-priming sewage pump use:
1, before use, should check whether the rotation direction of the pump is correct, rotation is flexible.
The liquid plug above the 2 and unscrew the pump body, fill liquid, and then tighten the screw plug. After the boot does not need to add liquid storage. Should not be in the case of insufficient pump storage to start running, otherwise the pump can not work, and easy to damage the mechanical seal.
3, boot, should first open the export flow control valve, in order to facilitate the self absorption process of gas discharge. After the start, opening and adjust the export flow control valve, the pressure gauge reading refers to the specified area (various pump type pressure control table), avoid the pump at work in designated areas within the lower, to prevent excessive shaft power caused by motor overload burned or overloaded and the pump cavitation, influence the normal operation of the pump, the pump strong vibration and noise.
4, the operation process, should always check the pump and motor temperature rise, such as the discovery of noise and other abnormal sound, should stop the inspection, troubleshooting, and then run.
5, shut down, should be the first to close the outlet flow control valve, and then shut down, so as not to siphon the role of the pump in the body of the lack of liquid storage.
6, regular refueling, maintenance, such as long-term cessation of the use of the pump should be disassembled for cleaning oil, properly preserved
