混流泵是利用叶轮旋转产生的离心力和推力联合作用工作，斜向出流，又称斜流泵，有蜗式（卧式）和导叶式（立式）两种。当原动机带动叶轮旋转后，对液体的作用既有离心力又有轴向推力，是离心泵和轴流泵的综合，液体斜向流出叶轮。因此它是介于离心泵和轴流泵之间的一种泵。混流泵的比转速高于离心泵，低于轴流泵，一般在300-500之间。它的扬程比轴流泵高，但流量比轴流泵小，比离心泵大。拍门 具有流道正向单向开启和反向关闭的作用。配重式 拍门 借助于配重的平衡作用，
Mixed flow pump is a combination of centrifugal force and thrust produced by rotation of impeller, oblique flow, also known as inclined flow pump, cochlear type (horizontal) and guide blade type (vertical). When the original motive forces the impeller to rotate, the function of the liquid is both centrifugal and axial thrust, which is the synthesis of centrifugal pump and axial flow pump, and the liquid is inclined toward the outflow impeller. Therefore, it is a kind of pump between centrifugal pump and axial flow pump. Mixing pump is higher than centrifugal pump, lower than axial flow pump, generally between 300-500. Its lift is higher than the axial flow pump, but the flow rate is smaller than the axial pump, bigger than the centrifugal pump. The racquet door has a positive flow direction and a one-way opening and reverse closing effect. The weight shot door is used to balance the weight,

 
在水流的作用下使门页自动开启或关闭，或稍加外力作用使门页开启或关闭；浮箱式  拍门 则利用门页在水中的浮力，在水流的作用下使门页开启或关闭。
To open or close the door automatically under the action of water flow, or a little external force can open or close the door. The float box is used to make the door open or close by the force of the water in the water.

Use/installation instructions

 
拍门安装使用注意事项：
Note:

 
1、拍门安装可以与法兰连接，可预埋，也可永插；
1. The door installation can be connected with flanges, but it can be buried, and it can be inserted forever.

 
2、配重拍门使用时，如果正向水力不足，不能开启门页，可根据安装位置需要设置不等重量的配重装置；
2. If the door is not enough to open the door, it can not open the door, but according to the installation position, it can be installed with different weights.

 
3、多台拍门安装时，如因起吊条件限制需分号安装，应注意标记，因每台拍门的门座和门页连接属偶配，不能互换；
3. As for the installation of multiple clapdoor, please pay attention to the mark if the hoisting conditions are required to be installed, because the door and door of each door are connected to the other side, which cannot be interchangeable;

 
4、穿墙管安装轴线与水平方向的夹角应大于或等于零度；
4. The Angle between the installation axis of the wall tube and the horizontal direction should be greater than or equal to zero;

 
5、拍门安装后，门座与门页间有3m不锈钢铸件 保定建筑设计 螺杆式启闭机 保定搬家 电缆挂钩 保定室内设计培训 冲压机m左右的间隙属正常现象，当门页受到反向回流水压时，间隙会减少；
5. After the door is installed, there is a normal phenomenon between the door seat and the door page between about 3mm. When the door is reversed, the clearance will be reduced.

 
6、为防止拍门铰链轴销松脱，拍门在安装后必须将铰链轴处的锁紧螺钉对准铰链轴槽锁紧，再将螺母并紧，并定期检查以防造成危险。
6. In order to prevent the pin release of the door hinge pin, the door must be fastened to the hinge shaft slot after installation, and the nut shall be tightened and checked regularly in case of any danger.
