Use
The DL and DLR s mould series pump is suitable in industry and city plumbing and the high-rise is boosted pressure send Shui s fire fighting supercharge and distant range is sent that heating of the Shui s , bathroom , boiler changes in temperature hydrologic cycle supercharge and air-condition refrigeration system send the occasions such as Shui Ji s equipment is formed a complete system etc . DL s mould medium use temperature does not surpass 80 ℃s , and DLR s mould medium use temperature does not surpass 120 ℃s .
主要特点
1.泵结构紧凑、体积小、外形美观,其立式结构决定安装占地面积小,其重心重合于泵脚中心,因而增强了泵的运行稳定性和使用寿命。
2.泵吸入口和吐出口均为水平方向,简化了管路的连接。
3.可根据需要,吸入口和吐出口可安装成同方向或90°、180°、270°几个不同方向以满足不同的连接场合。
4.泵扬程可根据需要增减水泵级数并结合切割叶轮外径予以满足,而不改变安装占地面积,这是其它泵类所不具有的。
5.电机外加防雨罩,泵可置于户外使用,取消泵房,节省建筑费用。
6.泵转子具有较小的挠度，且所选用的为4极电机,因此运行平稳、振动小、噪声低、使用寿命长。
The major characteristic
1. the pump structure is compact and the volume is small and the appearance is pleasing to the eye , his vertical structure decides the installation to cover an area of the area and is small , and his center of gravity is coincided at the Yu Bengjiao center , thus having strengthened the operating stability and the service life of pump
Simplify the connection of Guan Lu 2. the pump is inhaled the entrance with vomitting the export all for the horizontal direction
3. can inhaling the entrance according to the needs , with vomits the export can be installed into with the direction or several different directions 90 °s , 180 ° and 270 °s are in order to satisfy the different connection occasions
4. the pump lift can the increase and decrease water pump progression union combination according to the needs cut the impeller major diameter and give satisfiedly , and not changing the installation covers an area of the area , that this is other pumps is incomplete some
5. Guarding against the rain cover the electrical machinery is more , the pump can be placed in the outdoor and use , and cancels the pump house , and economizes the building cost
6. the pump rotor possesses the smaller deflection , the person who just chosen serve as 4 utmost points electrical machinerys , therefore moving smooth and steadyly and the vibration is small and the noise hangs down and service life is long
结构说明
DL型泵由电机和泵两部分组成,电机为Y型三相导步电机,泵和电机采用联轴器连接,整体为刚性连接使用时无需校正。泵由定子部分和转子部分组成。泵定子部分由进水段、中段、导叶、出水段、填料函体等零件组成。为防止定子磨损,定子上装有密封环、平衡套等,磨损后可用备件更换。转子部分由轴、中轮、平衡鼓等组成。转子下端为水润滑轴承,上部为角接触球轴承,泵的轴向力绝大部分自平衡鼓来承担,其余小部分残余轴向力由角接触球轴承来承受。进水段、中段和出水段的结合面用纸垫通过拉紧达到密封。轴封采用填料或机械密封,用户可根据需要选择。
泵旋转方向从驱动端向下看为逆时针方向转动。
The structure explanation
DL s mould pump is formed by electrical machinery and two parts pumps , and a step electrical machinery is led for Y s mould three-phase by the electrical machinery , and pump and electrical machinery use the shaft coupling to link , and need not proofread and correct when the whole links the use for the rigidity . The pump is formed by the stator partial sum rotor part . The pump stator part by intakes in the Duan middle section and leads Ye is appeared above water , and the part such as Duan s gland bos aspect etc are formed . For preventing the stator from wearing and tearing , close ring and balance cover etc are made up to the stator , and the available spare parts are changed after the wear . The rotor part is formed by axle , middle wheel and balance drum etc . Holding to the water lubricates the bearing under the rotor , top is for the horn contact ball bearing , and the axial of pump is energetically most , and the drum is undertaken from keeping balance , and all the other small part of remnants axials are energetically born by the horn contact ball bearing . Duan middle section and the section appearing above water intaking combines the face and with the paper pad by way of pulls tightly achieves closely . The axle seals to be used packing or the machinery seals up , and user can select according to the needs
The pump revolves the direction to be seen downward and moves for the contrary hands of a clock direction from the driving termination . |
