　　Fixed requirements for resource water intake pump ships

　　To build a water intake pump station near a reservoir in Rivers and Lakes or mountains, the traditional method is to build a dam by cofferdam, drain all the water in the cofferdam area, build a pump house, and then install pumps, valves, pipelines, controls, etc. Its disadvantages are as follows: 1 Long construction period, large cofferdam workload, and high cost; 2. The cost of the pump room is high (the greater the water level drop, the higher the cost of the pump room); 3. The traditional water intake pump station is located below the low water level and extracts bottom level raw water with high sediment content; Once the inlet pipeline is blocked by dirt, it is extremely difficult to detect and clean it; 5. The construction of pump stations has a significant impact on the environment and a low safety factor. Fifth. Only after confirming that there is no one working, can the pressure be increased. The personnel responsible for checking the power-off protection and secondary circuit are not allowed to perform any switching operations without the permission of the on duty personnel. The structure composition and working principle of the rotary arm water intake pump ship mainly include the pump ship hull (carrying pump float), water pump, rotary arm, crane, pipe fittings, valves, electrical components, etc. The pump ship (floating dock) can continuously supply water during the entire water level change and oscillation process. The rotary arm water intake pump ship (floating dock pump station) adopts PLC fully automatic control and manual control, with voltage of 380V, 6KV, 10KV available. The pump start stop operation is simple, the operation is safe and reliable, and the water intake and pump head are determined according to user requirements. Then it is stepped down by a transformer and sent to the low-voltage switchgear, which then goes to various power distribution panels. For the water intake floating pump station, it is very convenient. The pump ship type mainly adopts modular assembled floats, which are designed modularly and manufactured separately for easy land transportation; Transport to the construction site and assemble into a whole. To overcome the shortcomings in the construction and use of traditional water intake pump stations, our company has specially designed and developed various types of water intake pump ships and floating dock pump stations based on the different water intake requirements of different customers and the actual situation of each project. The water intake pump ship and floating dock pump station are suitable for water intake in Rivers and Lakes and stations built near the reservoir. Building a website is simple and convenient, with a short cycle and low cost; High water intake efficiency, good water quality, safe and reliable. Not affected by factors such as changes in water level or fluctuation frequency, the daily water intake ranges from several thousand cubic meters to several hundred thousand cubic meters. It has been widely used in projects such as waterworks, power plants, steel mills, chemical plants, cement plants, biological plants, paper mills, mines, and water conservancy irrigation.

　　Fixed requirements for resource water intake pump ships

　　The water pump ship is mainly composed of water pumps, floating boats, connecting pipes (used to connect the water pump outlet pipe and the onshore water pipeline), onshore water pipelines, valves, power supply and distribution equipment, lifting equipment, and mooring equipment. In addition, there are lighting, communication equipment, ship protection equipment, and water level alarm equipment. The water pump is installed on a floating vessel, which automatically rises and falls with changes in water level. By adjusting the relative connection between the connecting pipe and the onshore water pipeline, it adapts to the influence of geographical conditions and changes in water level drop.

　　The swing arm floating dock pump station is mainly used for parking facilities, farmland irrigation, water transfer in Rivers and Lakes, as well as water supply projects in metallurgy, mining, chemical industry, tanning, paper making, printing and dyeing, power, cold water plants and other fields; Main general operating conditions: The bank slope is steep, and the distance between the water intake and the offshore support pier is ≤ 30m; the water intake and pump head are determined according to customer requirements.

　　Pumps with cutting devices, multi-stage pumps, and submersible electric pumps with corrosive media are still rarely produced, but their market demand is high. Therefore, they have good development prospects. Developing high reliability mechanical seals is a key part of submersible electric pumps. Two single end mechanical seals are used, so that the pressure of the medium can act on the end face, and the leakage direction is internal flow. These are all advantageous, but the structure is slightly complex. Double end mechanical seals should be installed in the oil chamber, and different structural types should be used on both sides of the end face. If the resistance value is lower than the allowed small value, you should pay attention to it. The insulation damage of the winding wire of the water intake pump (floating) ship motor causes a decrease in resistance value, which requires major repairs and timely replacement of the winding; Secondly, overloading of the motor leads to aging of the winding insulation, resulting in a decrease in the insulation resistance of the motor. In addition to major repairs and replacement of the winding, reducing the flow rate of the water pump is also crucial; Thirdly, low insulation resistance of the motor caused by insulation damage or performance degradation of cable joints.

　　The float is designed modularly and manufactured separately for easy land transportation; It is transported to the construction site and assembled into a whole. The product uses of the swivel arm water intake pump ship. The swivel arm water intake pump ship is mainly used for municipal construction, farmland irrigation, water transfer in Rivers and Lakes, as well as water supply projects in metallurgy, mining, chemicals, tanning, paper making, printing and dyeing, power, water plants and other fields; Main applicable conditions: steep bank slopes. Its characteristic is that the circuit is relatively complex, and soft start, also known as thyristor voltage regulating start, uses the variable conductivity characteristics of thyristors to control the "soft start" and "soft stop" of motors. Its characteristics are small starting current (usually 2-3 times the rated current), smooth starting, no contacts, no sparks, small size, and light weight. It is generally used for starting motors above 11KW. Soft start with bypass is to use the soft start device for the starting process. After the start is completed, the water pump is switched to full voltage operation with a bypass contactor. Hunan Zhongda Energy saving Pump Industry Co., Ltd. Water intake pump ship.

　　Location selection of water intake pump ship

　　Fixed requirements for resource water intake pump ships

　　When selecting the water intake location for the pump ship, the following points should be noted:

　　(1) The river surface is wide, the water flow is stable, and there is sufficient water depth. During flood season, it will not overflow the slope, and during dry season, the water depth is not less than 1.0m.

　　(2) The riverbank is stable, with a slope gradient between 1:1.5 and 1:4.

　　(3) In navigable and rafting waterways, pump boats should maintain a certain distance from the main channel to prevent collisions with pump boats.

　　(4) Avoid large backflow areas to prevent a large amount of floating debris from accumulating at the inlet and affecting the inflow.

　　(5) There is a flat riverbank nearby that can serve as a maintenance site.

　　Usage Description of Ningwu Floating Water Pump Ship

　　(2) The water flow should be stable and avoid areas with large currents, rapids, and strong winds and waves; (3) Not affected by river navigation and raft release; The position of the floating ship should be kept at a certain distance from the waterway to avoid collision with each other. (4) During dry season, there should be sufficient water depth; The pump station with floating box structure is mainly applicable to municipal construction, farmland irrigation, water transfer in Rivers and Lakes and water supply projects in metallurgy, mining, chemical industry, paper making, printing and dyeing, power, water plants and other fields. The water level and water level drop are more than 40 meters; The bank slope is relatively flat, and the location of the water intake is more than 40 meters away from the shore; The water supply and pump head can be determined according to user requirements. The floating box structure pump station mainly consists of floating boats, water intake pumps, valves, water supply pipelines, lifting and maintenance devices, floating boxes, vacuum systems, fire protection systems, lighting systems, warning systems, life-saving systems, anchoring systems, electrical control systems, etc. When the water level is high, the floating boats and floating boxes are all floating on the water surface, and when the water level is low.

　　Floating ship water intake pump

　　Other than that, due to the different water intake conditions of any pumping station, the pump station parameters vary greatly, resulting in limited fluidity. The existing floating pump station technology makes it difficult for water intake pump ships to replace fixed pump stations. However, the water intake pump ship can serve as a supplement to the fixed pump station, providing emergency drought resistance measures and improving irrigation and water supply guarantee rates. It is still worth promoting vigorously. The float type water intake pump station produced by Hunan Zhongda Energy saving Pump Industry Co., Ltd. has solved this problem by using float type connections for all pipelines that change with water level changes.

　　If the newly purchased water intake pump (floating) boat fails to produce water or has a small water output during the * * * start-up, the motor should be checked for reverse rotation. Reverse rotation can cause no water output or a small water output. To avoid electric leakage and ensure safety, the power cord of the water intake pump (floating) ship must be selected according to regulations and should not be too long. Before starting, it is recommended to check the motor winding and cable insulation resistance of the submersible pump to confirm compliance with regulations before starting work. The use of the water intake pump (floating) ship is underwater; The medium being transported is a mixture of liquids containing solid materials; The pump and motor are very close, which makes the requirements for sealing, motor bearing capacity, bearing arrangement and selection of the water intake pump (floating) ship higher than those of general sewage pumps. However, we believe that it is necessary to install a protection system in the water intake pump (floating) ship. The wear and damage of flow components caused by high-speed water flow containing solid particles is the main reason for the shortened service life of water intake pumps (floating boats).

　　Material of the hull of the water pump ship

　　The hull materials of pump ships include wood, steel, steel wire mesh, cement, etc., and their characteristics are as follows:

　　(1) Wooden boat. In the early stages of construction, there is less construction and construction is faster, and it can be built in various places. However, it has low strength, is prone to decay, has poor fire resistance, short service life, high maintenance costs, and consumes a lot of wood.

　　(2) Steel ship. Without the drawbacks of wooden boats, and with high strength and long service life, well maintained steel boats can be used for decades. But the construction cost is relatively expensive and consumes more steel.

　　(3) Steel wire mesh cement ship. High strength, good durability, saving steel and wood, simple shipbuilding construction technology, low maintenance costs, low center of gravity, good stability, and long service life.

　　3. The installation method of submersible sewage pumps used for building fire elevator collection pits should adopt two fixed hard pipe connections or two fixed self coupling types, and the effective volume of the collection pit should not be less than 2.0m3, and the rated flow rate of the submersible sewage pump should not exceed 36m3/h. 4. Various series of submersible sewage pumps, such as AS, QW (WQ), and JYWQ, have two basic forms of installation: mobile installation and fixed installation.

　　The main features are applicable to large water intake projects near Rivers and Lakes and reservoirs. When the water level fluctuates, the position of the pump suction port will always remain unchanged with the fluctuation of the pump ship, and the pump operation is not affected by the height of the suction head. The PLC fully automatic control system is adopted, which is simple to operate. Compared with the civil engineering pump house: no cofferdam construction is required, the project progress is fast, the construction period is shortened, the cost is reduced, and the construction is safe and simple, with little impact on the environment. The trestle is connected to the support on the water delivery steel pipe. This situation can only be solved by replacing the new motor rotor or removing the old motor rotor, and then dropping it about 30 microns on the car surface to solve the problem of the submersible pump not rotating. The above five aspects are the main causes of noise and vibration in the water intake pump (floating) ship. You can eliminate them one by one according to the above solutions and solve them. We believe that after learning, you can quickly solve the problems you encounter. If you need to learn more about water intake pump (floating) ships, you can learn more about them on the Central Water Management website.

　　Having sufficient water depth, it is not easy to flood the slope during flood season, and the water depth should not be less than 1.0m during dry season. (2) The riverbank is stable, and the slope of the bank is between 1:1.5 and 1:4. (3) In navigable and rafting waterways, pump boats should maintain a certain distance from the main channel to prevent collisions with pump boats. (4) Avoid large backflow areas to prevent a large amount of floating debris from accumulating at the inlet and affecting the inflow. (5) There is a flat riverbank nearby that can serve as a maintenance site. When navigation conditions are met, a three-dimensional hull is adopted, and the pump ship is produced in a three-dimensional manner and transported by water to the construction site for installation without dead corners. When there are no navigable conditions, modular assembly of the hull is adopted, and the hull is developed and manufactured separately for land transportation; Transport to the construction site and assemble into a 360 degree structure. The hull materials of pump boats include wood, steel, steel wire mesh, cement, etc. (1) Wooden boats. At the beginning, there was less construction and construction was fast, and it could be built in various places. However, it has low strength, is prone to decay, has poor fire resistance, short service life, high maintenance costs, and consumes a lot of wood.

　　a. It is suitable for small water intake projects in Rivers and Lakes and beside reservoirs. In dry season and wet season, the water level drops greatly, the water level rises and falls rapidly, the bank slope is steep, and the water depth meets the water intake requirements. As long as buttresses are built at the bank end, the swing arm floating dock pump station is used for water intake. b. The floating dock can naturally adjust its rise and fall synchronously with the fluctuation of water level, and the position of the water pump suction port remains unchanged. The operation of the water pump is not affected by changes in suction height, and the length of the rotary arm is basically ≤ 30m.
