Application of Water Pump Ship

Description :

　　Application of rubber hose joints, ball joints, and sleeve joints on water intake pump ships

　　Floating activity connection

　　Floating whale style activity connection The so-called floating whale refers to a floating vessel that supports and connects steel pipes The connecting pipe is composed of rubber hoses, steel pipes, and floating whales. Each section of rubber pipe enables the water intake float to adapt to changes and movements in water level

　　This connection form is only suitable for situations where the water intake is small, the water level changes are small, and the water flow is stable.

　　Swing arm type active connection

　　The sleeve joint rocker arm connecting pipe is generally composed of 5-7 rotating sleeves, two sets of clamp shaped pipes, and one rocker arm pipe Both ends are installed on the shore pier and the steel frame support platform on the ship. The function of the 18-480 sleeve in the figure is to allow the water supply equipment to freely move up and down and reduce tilting and swaying under the action of wind, waves or external forces when the ship's hull is swollen. The 50 socket joint has the function of rotating around the axis of the rocker arm tube To reduce the torque experienced by the shaking tube; At the same time, it adapts to the free longitudinal undulations and head to tail bumps of the ship. Especially when the floating boat is located in a turbulent river section and the hull shakes violently, the setting of the sleeve is even more important. 6 and 7 sleeve joints are mainly used to allow the hull to move horizontally towards the riverbank when it moves away from the shore with the rise of water level, in order to avoid the impact of mainstream floods, ships, and floating objects. Secondly, it is to adapt the hull to the rotational displacement that occurs under the impact of rapids.

　　Most rocker arms are made of welded steel pipes. When the span of the rocker arm pipe is large and its own strength and stiffness cannot meet the requirements, additional reinforcement is necessary, such as using steel technology to connect the rocker arm pipe.

　　Floating ship water intake joint form

　　1) Rubber hose connector

　　This type of joint has good flexibility and elasticity, and can withstand a certain amount of internal pressure. It has a simple structure and is easy to process and disassemble. Mainly used for stepped connections of flexible connecting pipes with smaller diameters.

　　2) Spherical joint

　　A spherical joint consists of three parts: the ball seat, the ball center, and the pressure ring. The center of the ball rotates flexibly, but the large turning angle is only 27 on each side. For safety reasons, room must be left, and it is generally only used until 11-22. Spherical joints are generally used for stepped connections and can also be used for rocker arm type movable connections. Spherical joint processing requires high precision, manufacturing is complex, the joint is bulky, and disassembly is more complicated.

　　The ball joint can adjust the tightness of the gland during installation When in use Regularly remove the scale on the surface of the ball center and pay attention to oiling the slope material to make the ball center rotate flexibly.

　　3) Sleeve joint

　　A sleeve joint generally consists of a short tube with a retaining ring, a packing chamber composed of a sleeve, and a packing pressure ring. The various components of the tower free water supply equipment can be welded with steel plates, and the processing accuracy requirements are not high. It has the advantages of simple structure and convenient processing and manufacturing.

　　Due to the fact that the sleeve joint can only rotate along its axis, 5-7 joints are often used to form the rocker arm connecting pipe, in order to meet the requirement that the floating ship can rotate in all directions. However, the combination of multiple joints increases the weight and rotational friction of the connecting pipe. At the same time, when Xiao is subjected to external forces and generates bending moments, the packing is deformed due to compression, resulting in significant wear and serious water leakage The rotation is not flexible Frequently requiring maintenance. Especially for larger diameter sleeve joints, the above situation is more severe. The improved sleeve joint is composed of a pipe seat, a single flange shoulder short pipe, and ball bearings, which can withstand radial thrust, hence it is called a radial thrust flexible joint. The bending moment transmitted from the joint to the sleeve is borne by the ball bearing, and the sealing part only serves as a water stop. The filling material is not easy to wear and is durable in use.
