    闸门启闭机公司-闸门厂家电话螺杆式启闭机结构非常简单，而且安装也比较的简便，广泛使用在渠道的涵闸以及引水枢纽上的闸门启闭，但是，在使用过程中，常会出现顶闸，这种产生的原因是怎样的呢?顶闸发生的原因：1.人为因素引发的顶闸操作人员工作马虎，不按闸门启闭程序先检查，后操作或原操作人员因事请假，代班人员在不熟悉启闭程序和方法时，盲目操作。如将启闭方向反向，当闸门处在关闭状态时开闸，电动启闭时按错按钮或人工启闭时摇反方向，把闭闸的方向误操作为开闸;有的是在闭闸时操作人员思想不集中、闸到下限位置未能即时停机，有的是螺杆的限位螺母、限位标志移位，不起限位作用。电动启闭机还会遇到供电部门在维修电器设备或供电线路时电源相序变动，致使启闭机上的电动机改变了原运转方向导致启闭机启闭方向的改变，此时如闸门处在关闭状态时开闸，必将发生顶闸。

无需人力操作启闭力来自水源压力，当拍门内的水压大于拍门外侧压力则开启材质分为不锈钢、铸铁、型钢、复合材料(玻璃钢)等多种材料。而拍门又分为很多种，比如，浮箱式拍门，平板式拍门，套筒式拍门等等安装：把拍门门框直接与预埋螺栓联接，调正位置后紧固。注意拍门平面应与竖直面成一定的倾角。若为钢制拍门，用法兰连接或直接焊按连接。拉动门体上的吊耳，拍门启闭应灵活，否则应加以调整。用混凝土二次浇灌把拍门门框与土建接触面间的缝隙填实。每年应作一次防腐处理。定期检查密封止水弹性及密封效果并更换无效密封环。玻璃钢拍门（别称韧性拍门）简介：玻璃钢闸门玻璃钢拍门方型玻璃钢闸门玻璃钢拍门规格分圆形拍门和方形拍门两种。可根据出水口大小形状设产；

2.非人为因素引起的顶闸闸门在运行过程中，树木等漂浮物或石块等障碍物被高速水流带到闸底或冲到闸槽中卡住，若此时关闭闸门，当闸门下缘在未接触到闸底之前已被障碍物阻挡产生反力，但螺杆上的限位标志或限位开关还没有到位，不起限位停机或提醒操作人员停机的作用，故操作人员不会停机，启闭机将带动闸门继续下压，当反力超过启闭机或启闭台的承受耐力时，也必将发生顶闸。在使用过程中，要尤为注意到螺杆式启闭机的顶闸问题，如果出现这种，要及时进行处理，以免导致更严重的发生。

有特殊要求的地方还可以采用镍铬合金铸铁等耐腐蚀性更强的材料。铸铁闸门的止水副采用整体加工，止水效果好，金属止水使用寿命长。铸铁闸门是一种小型平板闸门，广泛使用于取水输水、市政建设，给水排水、农田灌溉等工程中，通常设置在渠道、涵管的进水口，用作工作闸门调节流量、控制水位，或用作检修闸门关闭孔口挡水。特点铸铁闸门一般设置有可调节的楔紧装置，楔紧副（如楔块与楔块、楔块与偏心销等）分别设在门体和门框上。耀禹水利机械厂坐落在人杰地灵的董振堂将军的故乡―河北省新河县（城西工业园区）。我厂是一家从事水工机械研发、生产、销售一体化服务规模型企业。主要产品：螺杆式启闭机、固定卷扬式启闭机、移动式启闭机、铸铁（生铁）闸门、铸钢（熟铁）闸门、钢制闸门、不锈钢闸门、玻璃钢拍门、清污机、拦污栅、橡胶止水等水利机械产品。

Screw hoist is very simple in structure and easy to install. It is widely used in culverts and diversion junctions. However, in the process of use, the top gate often occurs. What are the causes of the top gate? The reasons for the top gate: 1. Man-made factors caused the top gate operator. For sloppy, do not follow the gate opening and closing procedures first check, then operate or the original operator on business leave, the agent is not familiar with the opening and closing procedures and methods, blindly operate. If the opening and closing direction is reversed, when the gate is in the closed state, the opening and closing of the gate will be reversed by pressing the wrong button or swinging the opposite direction when the electric opening and closing is operated manually, and the direction of closing the gate will be misoperated as the opening of the gate; some operators will not concentrate when closing the gate, the brake fails to stop immediately at the lower limit position, and some are the limit nuts and limit signs of the screw. Displacement does not play a limiting role. Electric hoist will also encounter the phase sequence change of power supply when the power supply department maintains electrical equipment or power supply lines, which will cause the motor on the hoist to change its original operation direction and lead to the change of hoist hoist hoisting direction. At this time, if the gate is opened in the closed state, the top gate will occur. When the water pressure inside the door is greater than the pressure outside the door, the opening material can be divided into stainless steel, cast iron, profiled steel, composite material (glass fiber reinforced plastic) and other materials. There are many kinds of clapping doors, such as floating box type, flat type, sleeve type and so on. The frame of the clapping door is directly connected with the embedded bolt and tightened after adjusting the position. Attention should be paid to the obliquity of the slap door plane with the vertical plane. If the door is made of steel, it should be connected by flange or direct welding. Pull the lifting ear on the door body and slap the door open and close flexibly, otherwise adjust it. The gap between the door frame and the contact surface of civil engineering is filled with concrete secondary pouring. Antiseptic treatment should be done once a year. Check sealing elasticity and sealing effect regularly and replace invalid sealing ring. FRP clap door (also known as tough clap door) Brief introduction: FRP gate, FRP clap door, square type FRP gate, FRP clap door specifications are divided into circular clap door and square clap door. Production can be set according to the size and shape of the outlet; 2. During the operation of the top gate caused by non-human factors, obstacles such as floating objects such as trees or stones are carried to the bottom of the gate by high-speed flow or flushed into the gate slot to be stuck. If the gate is closed at this time, the lower edge of the gate will be blocked by obstacles before it touches the bottom of the gate, resulting in reaction, but The limit sign or limit switch on the screw is not in place, and it can not stop or remind the operator to stop. Therefore, the operator will not stop. The hoist will drive the gate to continue to press down. When the reaction force exceeds the endurance of the hoist or the hoist, the top gate will also occur. In the course of using, we should pay special attention to the problem of top brake of screw hoist. If this happens, we should deal with it in time to avoid more serious occurrence. Where there are special requirements, nickel-chromium alloy cast iron and other materials with stronger corrosion resistance can also be used. The water-stop pair of cast iron gate is processed as a whole, which has good water-stop effect and long service life of metal water-stop. Cast iron gate is a kind of small flat gate, which is widely used in water intake and transportation, municipal construction, water supply and drainage, farmland irrigation and other projects. It is usually set at the intake of channels and culverts. It is used as a working gate to regulate flow, control water level, or as a water barrier for closing the opening of overhaul gate. Characteristic cast iron gates are generally equipped with adjustable wedge devices, and wedge pairs (such as wedge and wedge, wedge and eccentric pin) are set on the door body and frame respectively. Yaoyu Water Conservancy Machinery Factory is located in Xinhe County, Hebei Province (Chengxi Industrial Park), the hometown of the outstanding General Dong Zhentang. Our factory is a large-scale enterprise engaged in research and development, production and sales of hydraulic machinery. Main products: screw hoist, fixed hoist hoist, mobile hoist, cast iron gate, cast steel gate, steel gate, stainless steel gate, FRP clap gate, cleaner, trash barrier, rubber water stop and other hydraulic machinery products. Structural Principle: The hoist is composed of electric device, machine base, wire rod, shield, electrical control box, etc. Motors or manual shank drive transmission devices (gears, worm wheels, worm or reducer) to run in vertical upward and downward motion. Thus the gate, fence and filter can be opened or closed. The operation specification of machinery is very important. It can not only ensure the safety of operation, but also maintain the performance of machinery. Closing speed refers to the speed at which a fast gate hoist falls by weight per meter/minute when the motor closes or the throttle oil valve in the hydraulic circuit opens. Operating speed refers to the speed of the motor of the mobile hoist operating structure, which is running along a straight line, per meter/minute at rated speed. Rotary speed refers to the rotating speed of rotary structure motor at rated speed, unit meter/minute. Span span refers to the distance between the running track centers of the movable hoist, i.e. the gauge of the cart. The working level of crane refers to the degree of work idleness of crane, that is, the total running time of hoist within one year. Lightweight work system refers to short running time and long intermission time.  Such as: gate and trash barrier, etc. Intermediate working system refers to the frequent use of boot-and-shut machines. For example, miter gates of ship locks, etc. Manual screw hoist The gate of the hoist can stay at any position to complete self-locking. It is a very advanced equipment. Screw start。
