How the pulp pump works
First about the relationship between centrifugal pump and slag pump, and then the principle of slag pump is naturally b. The concept of centrifugalness is originally from the pump. There are many types of pumps that can be divided into dozens of categories according to different angles. The centrifugal pump is divided from the working principle of the pump and is used by centrifugal force to achieve the process of pressurizing the conveying medium. There are also common types including screw principle, plunger principle, etc. can be divided into different from centrifugal principle pump. After speaking of the concept of centrifugal pump, in addition to the slag pump, the slag pump is divided from another angle, that is, from the conveying medium to divide. As the name implies, the slurry pump conveys a mixture of solid particles and water containing slag. However, in principle, the slag pump belongs to a kind of centrifugal pump. So the two concepts are b.
The main working parts of the centrifugal pump are the impeller and the case, where the impeller unit is located on the shaft and is connected to the prime mover to b a whole. When the prime rorlasta drives the impeller rotation, the blades in the impeller force the fluid to rotate, i.e. the blade works on the direction of the fluid's motion, thus forcing the pressure potential and kinetic energy of the fluid to increase. At the same time, the fluid, under the b of inertial forces, flows from the center to the edge of the impeller and flows out of the impeller at a high speed, into the pressure chamber, which is then discharged by the diffusion tube, a process known as the pressure water process. At the same time, because the fluid in the center of the impeller flows to the edge, a low-pressure zone is bed in the center of the impeller, when it has enough vacuum, under the b of the suction end pressure (generally atmospheric pressure), the fluid enters the impeller through the suction chamber, a process known as the absorption process. As the impeller rotates continuously, the fluid is continuously discharged and inhaled, bing continuous work.
The process of working with centrifugal pumps, including slag pumps, is actually a process of energy transfer and conversion. It transmits the mechanical energy of the motor at high speed, through the blades of the pump, and converts it into the pressure and kinetic energy of the pumped fluid.

要求運(yùn)行平穩(wěn)的工況當(dāng)泵的流量要求很高時(shí),如果是單吸泵則要有很大的泵入口和出口口徑,同時(shí),轉(zhuǎn)速不能太大,需穩(wěn)定在1450rmp左右,若采用雙吸泵,泵的尺寸和重量都可以相對(duì)減小,轉(zhuǎn)速也可以提高,容積效率增加。雙吸中開(kāi)泵的拆卸方法:只要拆開(kāi)泵蓋,不必拆卸進(jìn)出水管路,就能拆除整個(gè)轉(zhuǎn)子部件;關(guān)閉進(jìn)出口閥門(mén),打開(kāi)螺塞和放氣螺塞,將水和氣體排出;松開(kāi)泵聯(lián)軸器與電機(jī)聯(lián)軸器之間的緊固件;松開(kāi)并壓出填料蓋;松開(kāi)泵蓋與泵體之間的連接螺栓,拿掉泵蓋;松開(kāi)軸承體和泵體之間的連接螺栓,拆下轉(zhuǎn)子部件;拆下泵聯(lián)軸器和軸承壓蓋;松開(kāi)螺母,從軸上壓出軸承體、軸承體包括軸承,確保壓力均勻,不要用榔頭,否則會(huì)損壞軸承;拆下填料、填料環(huán)和襯套。
