　　Characteristics and advantages of Shandong water pump ships

　　According to the current regulations of the "Code", except for the use of fabric reinforced rubber hoses for the connection of mobile installation hoses, the discharge pipe materials for water pumps (floating) ships can be made of hard plastic water supply pipes, centrifugally cast ductile iron water supply pipes, steel pipes, composite pipes, etc. The pressure bearing capacity of pipes and fittings should not be less than 0.6MPa.

　　Before stopping the water pump, the valve should be closed. After starting the water pump, gradually open the valve to prevent overcurrent during startup. There are six key points for the construction and installation of water intake pumps (floating boats), and the water intake pumps (floating boats) are automatically controlled by liquid level automatic control devices. In addition to float type liquid level switches, if the sewage does not contain or only contains a small amount of suspended impurities, input pressure sensors and supporting secondary instruments can also be used for automatic liquid level control devices. The automatic liquid level control device installed in the sewage tank (collection well) should be as far away from the inlet as possible.

　　The rocker arm type water intake pump ship automatically rotates and adjusts the slope of the connecting steel pipe during water level rise and fall to match the lifting of the hull, and does not need to interrupt pumping, making management convenient. The hull can also rotate horizontally and dock at the shore during flood periods for easy anchoring, but the sleeve has high friction during operation and is prone to water leakage. Rubber joint steel connecting pipe connects the two ends of the steel connecting pipe with rubber hoses with flanges, fixed on the steel structure's approach bridge. One end of the steel approach bridge is connected with a suspension structure on a pier or frame that is higher than the flood on the shore, and the other end is located on a spherical support on the side of the pump ship. Two sets of springs that can withstand tension and compression are installed on the spherical support to buffer the pump ship's offshore or shore movement caused by wind and waves. This form is suitable for situations with large water intake, fast river flow, and steep riverbanks, and can adapt to the movement and lifting of pump boats without the need to replace joints. Due to the onshore joint being above the * * * water level and the approach bridge serving as a traffic bridge, operation and management are convenient.

　　If in emergency use, the water pump must be adjusted using the outlet valve installed on the outlet pipe, usually using a self operated regulating valve or other methods to reduce the outlet flow and prevent motor overload. Pay attention to the temperature of the motor. If the motor overheats, reducing the water outlet flow or shutting it down can prevent the motor from burning out in a timely manner. Some users force a decrease in flow by reducing the power supply voltage, which will increase the motor load. In fact, on the contrary, the unit outlet pipes of centrifugal pump irrigation stations are equipped with valves to reduce the motor load.

　　(9) Easy disassembly and assembly without the need for specialized tools. For the construction of pump stations in Rivers and Lakes or reservoirs, * * * the traditional method is to build dams first, drain the water in the area, build pump houses, and then install pumps, valves, pipelines, controls, etc. Its characteristics include long construction period, large workload, high cost of pump room, and the higher the water level drop, the higher the cost of pump room; Traditional pump stations have their water intake fixed below the low water level, and the water source is the raw water from the bottom layer, which has a high sand content. The inlet pipe sinks deeper into the bottom of the water, wasting materials. In case of blockage by dirt, it is difficult to detect and clean it; The construction of pump stations has a significant impact on the environment and a low safety factor. In order to overcome the shortcomings of traditional pump station construction and improve economic benefits, our company has specially developed floating ship and float type water intake pump stations based on the requirements of different customers and combined with actual geographical conditions. The pump station structure is based on a floating ship or buoy deck as the working platform, and other facilities such as water pumps, valves, pipelines, and controls are installed on the ship.

　　Used for taking water from the collection pit of building fire elevators

　　The installation method of the water pump (floating) ship should adopt a fixed type with two hard pipes or a fixed self coupling type with two fixed pipes, and the effective volume of the collection pit should not be less than 2.0m. The rated flow rate of the water intake pump (floating) ship should not be less than 36m 3/h. 、 QW (WQ) and JYWQ various series of water intake pumps (floating) ships have two basic forms of installation: mobile installation and fixed installation.

　　For water pump ships, China's water pump (floating) ships, submersible axial flow pumps, pneumatic gate valves and other pump and valve industries will also bring new opportunities for sustained growth. The domestic general machinery industry has made great progress, especially in the continuous improvement of the technical level of pump and valve products, and can provide some intermediate products for the market. Optimize its structural design and further improve the performance of submersible sewage pumps. The development of the sewage pump industry is closely related to the development of real estate, construction, industry, and engineering projects. In recent years, with the continuous deepening of domestic environmental and infrastructure policies, China's water intake pump (floating) ship industry will usher in new opportunities for sustained growth. With its good application, water intake pump (floating) ships have been increasingly valued by people and have a wider range of uses. They have evolved from simply transporting clean water to now being able to transport various types of domestic sewage, industrial wastewater, construction site drainage, liquid feed, etc. They play a very important role in various industries such as municipal engineering, industry, hospitals, construction, hotels, and water conservancy construction.

　　Solved the difficulty of fixed pump station inlet pipes being buried underwater and prone to blockage and difficult to clean; f. The safety equipment is complete. Reduce traffic; Improper assembly of the electric pump may also cause the failure of the thrust bearing of the water intake pump (floating) ship. In this case, it is necessary to align the axis of the two machines and reassemble them. It is not difficult to see that there are many reasons for the failure of the thrust bearing of the water intake pump (floating) ship. Only by identifying the cause can the problem be quickly and accurately dealt with to ensure the normal operation of the water intake pump (floating) ship. Considering that the motor of the water intake pump (floating) ship works underwater for a long time. The water pump ship can achieve surface water intake, and it is generally advisable to maintain a depth of 1.5-2m below the water surface for water intake. It is also suitable to take water in the concave bank of the river where there is less sediment and better water quality, making management and maintenance inconvenient. In addition to managing and maintaining the main body and equipment of the pump ship, every time there is a fluctuation in the water level at the water intake or displacement of the pump ship. Exclusion measures should be taken to control the allowable deviation of the installation elevation of the water pump, and it should not be arbitrarily expanded; Before the trial operation of the water pump, run the motor idle first.

　　Hunan Zhongda Energy saving Pump Industry Co., Ltd. water intake pump ship, inspect valves, and regularly maintain valves; Clean up blockages in pipelines and impellers, frequently salvage debris in the reservoir: clean debris or replace wear-resistant rings; Identify the reasons for changes in water quality and take measures to address them; Strengthen or replace the impeller; After checking the cause, install or replace one-way valves. In order to ensure the normal use and service life of the water intake pump (floating) ship, regular inspections and maintenance should be carried out: replace the sealing ring: after long-term use in sewage medium. But this is not the key to the problem. The protection system is just a remedial measure after the pump fails. It is a relatively passive method. The key to the problem should be to start from the root and thoroughly solve the problems of the pump in terms of sealing, overload, etc. This is the more active method. During the operation of the water intake pump (floating) ship, this may occur. Secondly, the excessive flow rate of the water pump will cause the rotor to move up and down, and the ammeter will also swing abnormally. Thirdly, the dynamic water level will drop near the mouth of the water pump, and the water supply from the water pump will be insufficient.

　　The water pump ship has a high foundation, high center of gravity, poor stability, and high vibration. The through type refers to installing the water pump unit on the bottom frame of the cabin, as shown in Figure 2. Therefore, the center of gravity is low, the stability is good, and the vibration is small, but the management, operation, and ventilation conditions are poor. At the same time, because the suction pipe passes through the ship's side, it is only used for steel structure hulls. Among them, whether the rolling bearings are properly cleaned will also affect the bearing noise and service life of the water intake pump (floating) ship. Before cleaning, remove the anti rust agent used for sealing. Before cleaning the rolling bearings, first remove the anti rust agent used for bearing sealing. For bearings using grease anti rust grease, remove the packaging material first, and then place the bearings in a tank containing 100-120T of No. 3 spindle oil and heat for 10-15 minutes before taking them out. For bearings using water-based anti rust grease for the cage, use water-based anti rust agent for the cage, while for bearings using oil-based anti rust grease for other parts, a sodium oleate soap solution with a content of (2-3)% or 664 cleaning agent solution can be used.
