3GR85×4W21三螺杆泵/稀油站柴油输送泵

3GR85×4W21三螺杆泵/稀油站柴油输送泵
1.螺杆主杆与从杆.螺杆就相当于螺杆泵的心脏.其主要原理就是相互啮合的螺杆沿轴向输送介质（主要材质为40Cr, 38CrMoAl)
1 screw the main rod and screw rod. From the heart is equivalent to the screw pump. Screwthe main principle is meshed with each other along the axial transport medium (the main material for the 40Cr, 38CrMoAl)
2.衬套螺杆泵的衬套及泵体的长度应至少能覆盖一个导程的螺杆副.（衬套主要材质为HT200/QT450-10/ZCuSn5Pb5Zn5/ZL109外壳为HT200/QT450-10）
Bush and a pump body 2 Bush screw pump length of the screw pair can at least cover a lead.(Bush the main material for the HT200/QT450-10/ZCuSn5Pb5Zn5/ZL109 shell is HT200/QT450-10)
3.泵体螺杆泵的衬套及泵体的长度应至少能覆盖一个导程的螺杆副.（材质为HT200/QT450-10）
Bush and the pump body and pump body pump 3 screw length of screw pair can at leastcover a lead (material HT200/QT450-10).
4.机封座铸件直接加工（材质为HT200/QT450-10）
4 mechanical seal seat casting process directly (material HT200/QT450-10)
5.密封压盖密封压盖一般为车床加工产品.是连接密封件的重要部件.其精度要求非常高。
5 sealing gland gland for the general lathe machining products. Is an important component inthe connection seal. The very high accuracy requirements.
6.前端盖铸件直接加工（材质为HT200/QT450-10）
Direct casting 6 front cover (material HT200/QT450-10)
7.后端盖铸件直接加工（材质为HT200/QT450-10）
Direct casting 7 rear cover (material HT200/QT450-10)
8.安全阀安全阀是起到保护泵及电机不被损坏的一套装置.由于泵出厂前就设定了使用的压力.故在超过此压力时.就会自动开启泄压.起到了一定保护的作用。
8 safety valve safety valve is a device to protect the pump and motor are not damaged.Because the pump factory set using pressure. So in excess of this pressure. Pressure reliefwill automatically open. Played a certain role in the protection of the.
9.易损件为机械密封.轴承螺杆泵密封分为.机械密封（适用于介质润滑性好温度小于80°)填料密封(适用于润滑介质较差粘度大温度小于150°）和波纹管密封（适用于介质粘度大温度在250°）
