PWDL多吸頭排污泵參數(shù)流量揚程
多吸頭型為單級、單吸、立式離心渣漿泵，該系列泵采用國際上先進的固液兩相流理論，按最小損失原則設計。其過流部件的幾何形狀符合介質的流動狀態(tài)，減少了渦流和撞擊等局部與沿程水力損失，從而減輕了過流部件的磨損，提高了水力效率，降低了運行噪音和振動；多吸頭系列渣漿泵的過流部件采用高硬合金鑄鐵，其材質具有高抗磨性、抗腐蝕性、抗沖擊性能、從而使其壽命提高 多吸頭型渣漿泵一般浸入池內或坑內工作，不需要任何軸封和軸封水。加長軸系列的液下泵，可適用于液位較深的工況。該型泵適用于礦山、冶金、電力、煤炭、化工、建材等行業(yè)，輸送含有固體顆粒的磨蝕性和腐蝕性漿體，其固液混合物最大重量濃度：灰漿45%、礦漿60%。
產(chǎn)品結構：
SP型渣漿泵主要由葉輪、渦殼、后護板、軸套、支架、支撐板、軸、軸承、軸承體等零件組成。葉輪、渦殼、后護板的材質為高鉻合金鑄鐵，葉輪與軸采用螺紋聯(lián)接，渦殼、支架、軸承體用螺栓聯(lián)接。泵軸與電機可采用聯(lián)軸器直聯(lián)傳動或皮帶傳動。SP型泵的軸承采用油脂潤滑。該系列泵為無軸封泵。
Parameter flow head of pwdl multi suction sewage pump
The multi suction head type is a single-stage, single suction, vertical centrifugal slurry pump. The series of pumps adopt the international advanced solid-liquid two-phase flow theory and are designed according to the principle of minimum loss. The geometric shape of the flow passage parts conforms to the flow state of the medium, which reduces the local and along flow hydraulic losses such as eddy current and impact, so as to reduce the wear of the flow passage parts, improve the hydraulic efficiency, and reduce the running noise and vibration. The flow passage parts of the multi suction series slurry pump are made of high hard alloy cast iron, which has high wear resistance, corrosion resistance and impact resistance The multi suction head slurry pump is generally immersed in the pool or pit to work, without any shaft seal and shaft seal water. The long shaft series of submerged pump can be used in the condition of deep liquid level. The pump is suitable for mining, metallurgy, electric power, coal, chemical industry, building materials and other industries, conveying abrasive and corrosive slurry containing solid particles. The maximum weight concentration of solid-liquid mixture is 45% of mortar and 60% of pulp.
Product structure:
SP type slurry pump is mainly composed of impeller, volute, rear guard plate, shaft sleeve, bracket, support plate, shaft, bearing, bearing body and other parts. The impeller, volute and rear guard plate are made of high chromium alloy cast iron. The impeller and shaft are connected by thread, and the volute, bracket and bearing body are connected by bolts. The pump shaft and motor can be driven by coupling directly or by belt. The bearing of SP pump is lubricated by grease. The pump has no shaft seal.
