特征描述
Feature description
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 the use of centrifugal force generated by the rotation of the impeller and thrust joint work, oblique flow, also known as oblique flow pump, there are snail (horizontal) and guide vane (vertical) two. When the prime mover drives the impeller to rotate, the centrifugal force and axial thrust force are applied to the liquid. The centrifugal pump and axial flow pump are integrated, and the liquid is inclined out of the impeller. Therefore, it is a pump between the centrifugal pump and the axial pump. The specific speed of the mixed flow pump is higher than that of the centrifugal pump, which is less than that of the axial flow pump, usually between 300-500. Its head is higher than the axial pump, but the flow is smaller than the axial pump, larger than the centrifugal pump. The utility model has the function of forward unidirectional opening and reverse closing of the flow passage. The counterweight type flap door is balanced by the counterweight,
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
The door is opened or closed automatically under the action of water flow, or the door page is opened or closed by a little external force; the floating box type is opened or closed
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。
The door utilizes the buoyancy of the door page in the water and opens or closes the door page under the action of the flow.

Use / installation instructions
拍门安装使用注意事项：
Door installation, use notes:
1、拍门安装可以与法兰连接，可预埋，也可永插；
1, the door can be installed with the flange connection, can be buried, but also permanently inserted;
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, the counterweight beat the door, if the forward hydraulic insufficiency, can not open the door page, according to the installation position, need to set different weight balance device;
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, the installation of more than a dozen doors, such as lifting conditions should be installed semi colon, should pay attention to mark, because each beat the door door and door page connection is a pair, can not be interchanged;
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 and the horizontal direction of the through wall pipe shall be greater or equal to zero;
5、拍门安装后，门座与门页间有3mm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, the door is installed, and the clearance between the portal page about 3mm is a normal phenomenon, when the page is a reverse flow of water pressure, the gap 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 door hinge shaft pin loose, the door must be installed after the hinge shaft at the hinge screw on the hinge shaft groove locking, and then tighten the nut, and regular inspection, in case of danger.
7、本公司目前生产的拍门主要适用于单向流水的圆形出水口，如用户需要适用于方形出水口的拍门可向本公司定做。
7, the company's current production door is mainly applicable to one-way water circular water outlet, such as the user needs for square water outlet door can be customized to our company.
