WHTC series vacuum-assisted trailer-type mobile pumping station is a special mobile pumping station for flood prevention and drainage. Shanghai Weihu Pump Industry Co., Ltd. is the latest product launched after many technical improvements based on many years of experience in instrument rescue and drainage and suggestions from customers. Fast hauling and loading and unloading, simple operation, and strong environmental adaptability. It has intelligent digital control, one-button startup, maintenance-free, all-weather urban road drainage, and is mainly used for emergency drainage drainage in areas without power. Main force.
Conditions of Use:
It has intelligent digital control, one-key startup, maintenance-free, all-weather urban road drainage, and is mainly used for emergency drainage and drainage rescue in areas without power. It is the main force of flood prevention, drainage and drought resistance at this stage.
Structural characteristics and working principle:
1. The double-suction self-priming pump runs smoothly. The double-suction impeller designed to optimize the operation reduces the axial force to a minimum, and has excellent hydraulic performance blades. The surface is precision-cast. Significant resistance to cavitation and high efficiency. The pump body is made of nodular cast iron. The casting efficiency is higher, and the machining and casting costs of nodular cast iron are more prominent. The impeller is made of high-quality ZG1Cr13N19i stainless steel, the pump shaft is made of 3Cr13, and the pump and pipeline connection adopts the standard circular flange in accordance with GB / T17241.6.
2. The support distance between the two ends of the water pump is short. The pump shaft is supported by 2 high-precision rolling bearings. Both the bearing cavity and the sealed cavity adopt rare lubrication. The pump runs stably, with low vibration and noise, and can run at a speed of more than 15%, which makes the water pump adapt to a wider range. The bearings are made of high quality brand bearings to ensure smooth operation, low noise and long service life.
3. The same rotor can run in reverse, reducing the risk of water pump damage caused by water hammer.
4. The design of double suction impeller flow channel + non-blocking impeller can discharge solid particles at 40-60mm, fiber length 50-120mm, strong passing ability, good wear resistance and so on.
5. The excellent hydraulic model is adopted to make the efficiency of the pump 2-3% higher than that of similar pumps, which greatly reduces the operating cost of the pump. The necessary cavitation allowance is reduced by 1-3 meters, and the actual suction distance is greater than 6.5m after third-party field testing, and it has excellent performance in large-caliber self-priming pumps.
6. The mechanical seals are selected from domestic high-quality hard paper alloy mechanical seals. The mechanical seal can ensure no leakage for 8000 hours of operation.
7. It has a dry-running design. The self-priming pump can start pumping without pumping water. The design principle is: the pump cavity is provided with sealing jackets at the front and rear ends of the impeller, and the pump mechanical seal is installed in the sealing clamp. Inside the sleeve, the jacket is separated from the water in the pump cavity by a seal, and high-efficiency lubricating oil is injected into the seal jacket, thereby ensuring that the seal can be fully lubricated and cooled during dry running of the self-priming pump. Ensure that the self-priming pump can continuously dry run for more than 120S.
8. The marine gear ring coupling is selected for the connection between the engine and the pump shaft. The high elasticity can effectively absorb shocks and vibrations, reduce noise, simple structure, and easy disassembly. It can be disassembled and moved without moving the equipment at both ends. Very strong ability and small square force.
9. The engine is produced by Weichai Co., Ltd., a diesel engine enterprise group, which produces engines of Deutz III emissions, which are characterized by fuel-saving, environmental protection, and automatic acceleration of high-pressure common rails.
10. The vacuum auxiliary system is selected, which has a large exhaust volume and quicker water loading.
11. The inlet and outlet of the pumping station adopts a 1-to-5 design and Paul's quick connector connection, which greatly improves the rapid drainage efficiency of the pumping station.
12. Intelligent digital controller: fault alarm, digital LCD display, monitoring engine operation data throughout the process, and ensuring the safe operation of the unit.
