In order to water pump suction pipe, memory, import needs bottom valve pump working, bottom valve caused great losses. So-called self-suction pump, is in start without irrigation (before the first start after installation to infuse water), still for a short time after operation, the effect on pump itself, which can be put into water, the normal work. According to the principle of self-suction pump function can be divided into several categories: 1.the gas-liquid hybrid (including mixed type within and outside the mixed type), 2 water wheel, 3 jetting (including liquid jet and the gas jet). Gas-liquid hybrid self-suction pump working process: because of the pump suction pump stalled after the special structure, the pump body, being a certain amount of water pump impeller rotation due to start again, inhaled air and water pipe, and is fully mixing gas water separation chamber to water, air separation chamber of the upper spillover of water, gas, and the return of impeller residual air suction pipe, the pump suction pipe and until all the gas discharge, complete, and normal self-suction pump. Water wheel self-suction pump water ring round is in a combination of pump impeller and using water loop, wheel, gas discharge self-priming. When the pump is normal work, but through the valve and pump water loop truncate the channel impeller, and put off the liquid water ring round. Jetting self-suction pump, the centrifugal pump and jet pump injector (or on), spray nozzle, vacuum suction caused realization.自吸泵应用范围:  1、适用于城市环保、建筑、消防、化工、制药、染料、印染、酿造、电力、电镀、造纸、工矿冲洗、设备冷却等。   2、装上摇臂式喷头、又可将水冲到空中后,散成细小雨滴进行喷雾,是农场、苗圃、果园、菜园的良好机具。   3、适用于清水、海水及带有酸、碱度的化工介质液体和带有一般糊状的浆料(介质粘度<100厘珀、含固量可达30%以下)。   4、可和任何型号、规格的压滤机配套使用,将浆料送给压滤机时进行压滤的配套泵种。Scope of application: self-suction pump:  1, suitable for urban environmental protection, construction, fire control, chemical, pharmaceutical, printing, dyeing, brewing, electric power, electroplating, papermaking, and equipment cooling, etc.  2, rocking sprinkler, can pour water into the air and become small drips to spray, farms, nurseries, is a good tool for orchard, garden.  3, suitable YuQingShui, seawater and with acid, alkalinity of chemical liquid medium size and general paste viscosity < 100 per cent (medium, including solid volume reaches 30% below).  4, and any type and specification of filter used for pressure filter, size of filter press machine are the most ideal.自吸泵工作原理与结构说明:  该泵均采用轴向回液的泵体结构。泵体由吸入室、储液室、涡卷室、回液孔、气液分离室等组成,泵正常起动后,叶轮将吸入室所存的液体及吸入管路中的空气一起吸入,并在叶轮内得以*混合,在离心力的作用,液体夹带着气体向涡卷室外缘流动,在叶轮的外缘上形成有一定厚度的白色泡沫带及高速旋转液环。气液混合体通过扩散管进入气液分离室。此时,由于流速突然降低,较轻的气体从混合气液中被分离出来,气体通过泵体吐口继续上升排出。脱气后的液体回到储液室,并由回流孔再次进入叶轮,与叶轮内部从吸入管路中吸入的气体再次混合,在高速旋转的叶轮作用下,又流向叶轮外缘......。随着这个过程周而复始的进行下去,吸入管路中的空气不断减少,直到吸尽气体,完成自吸过程,泵便投入正常作业。   在一些泵的轴承体底部还设有冷却室。当轴承发热引起轴承体温升超过70度时,可在冷却室处通过任意一只冷却液管接头,注入冷却液循环冷却。泵内部防止液体由高压区向低压区泄漏的密封机构是前后密封环,前密封环装在泵体上,后密封环装在轴承体上,当泵经*运转密封环磨损到一定程度,并影响到泵的效率和自吸性能时,应给予更换。Self-suction pump working principle and structural description:This pump adopts the axial liquid pump body structure. By the pump body, reservoir, vortex volume chamber, liquid, gas and liquid separation chamber, etc, the pump impeller normal starting, the room will suck the air suction pipe and together, and in the impeller inhaled to compley mixed in only centrificating, liquid entrainment from the gas flow vortex roll in outdoor margin of impeller formed on the thickness of certain white foam and high-speed liquid ring. Gas-liquid mixture through tube into the gas-liquid separation diffusion. At this time, due to the sudden reduced velocity, lighter gases from the mixture of liquid, gas was separated by casting pump body continues to rise. After the degassing liquid storage room, and back again by the backflow into the hole, and the impeller impeller from inhalation of gas pipeline, inhaled again in high speed rotating impeller, and under the direction of impeller tillu... . With the process of the cycle, the air suction pipe, and devoured gas, finish until self-priming pumps and investment, the normal operation. In some of the pump body bottom bearing with cooling room. When bearing heating temperature rise caused more than 70 degrees bearings, cooling room place in any one cooling fluid pipe joints, cooling fluid circulation cooling. By high internal prevent liquid pump seal leakage from the low pressure area is around before sealing ring, in the pump body, after sealing in bearing on the body, when the pump running through long-term ring wear to a certain degree, and affect the efficiency of pumps and self-priming performance, should give change.
