Diesel engine double suction centrifugal pump

SCDiesel engine double suction centrifugal pumpIt is an emergency water supply and drainage equipment powered by a diesel engine to drive a new high-performance double suction open centrifugal pump. It is mainly suitable for water plants, air conditioning circulating water, heating pipe network systems, building water supply, irrigation, etcPlaces where liquids are transported, such as drainage pump stations, power plants, industrial water supply systems, fire protection systems, shipbuilding industries, and mine water supply and drainage systems.

The SC type new high-performance double suction split centrifugal pump has a much higher efficiency than SH, S, SA, SLA, and SAP type pumps, and is an upgraded product of double suction split pumps. Transportable media: clean water, hot water (200 ℃), corrosive liquids, oil, etc.

Diesel engine pump assembly

cost advantage

1. By selecting an excellent hydraulic model, the efficiency of the pump is 2-3% higher than that of similar pumps, greatly reducing the operating cost of the pump.

2. The vacuum height is increased by 1-3 meters, thereby reducing civil engineering investment and extending the service life.

3. Imported bearings are selected, and the material of the parts can be selected according to user requirements, so that the pump can adapt to various on-site operating conditions, greatly reducing costsReduced maintenance costs.

SCDiesel engine double suction centrifugal pumptechnical advantage

1. The support spacing between the two ends of the water pump is short, the pump runs stably, has low vibration and noise, and can be operated at an appropriate speed, making the water pump more adaptable to a wider range.

2. The inlet and outlet are on the same straight line, making the pipeline layout simple, convenient, and beautiful.

3. The same rotor can run in reverse, reducing the risk of water hammer causing damage to the water pump.

4. The high-temperature design of the water pump adopts intermediate support, thickened pump body, sealed cooling, and thin oil lubrication for the bearings, making

The water pump can be applied to operating environments up to 200 ℃, especially suitable for the requirements of heating pipe networks.

5. The pump body can be installed vertically or horizontally according to changes in usage conditions, and mechanical seals or packing seals can be used for sealing.

6. The appearance of the water pump should be industrialized designed with clear lines that conform to modern aesthetic standards.

Maintenance advantages

1. Containerized mechanical seals make replacing mechanical seals an easy and simple task.

2. The application of elastic prestressing assembly makes the assembly and disassembly of rotor components simple and quick.

3. No need to adjust various clearances during assembly.

The diesel engine water pump unit is a driving pump powered by a diesel engine. The pump unit is driven by the diesel engine through an elastic coupling. It is an integrated and highly integrated equipment specially developed by our company to meet the special requirements of domestic and foreign customers for diesel engine emergency pump systems used in industrial emergencies such as boiler feedwater and high-temperature circulating water.
The diesel engine water pump unit has the following characteristics:
1. Automatic start: The diesel water pump unit can automatically start and operate at full load within 15 seconds after receiving a fire alarm/pipeline pressure/power outage/or other start signals;
2. Automatic charging: The battery can be charged automatically by the mains power or diesel engine charging motor to ensure the smooth start-up of the unit;
3. Automatic alarm: It automatically alarms and protects against faults such as low oil pressure and high water temperature in diesel engines, and alarms and shuts down when overspeed occurs;
4. Automatic preheating: put the diesel engine in a hot standby state to ensure emergency operation;
5. Direct connection: The diesel engine and water pump used in diesel water pump units below 360kw are directly connected through elastic couplings, reducing the number of failure points and greatly shortening the starting time of the unit, increasing the reliability and emergency performance of the unit;
6. Users can also request the setting of other alarm outputs: the diesel engine power driven pump (or fire pump set) is securely and tightly installed on a common chassis with horizontal centrifugal pumps and diesel engine electrical instruments and other equipment Connected to the electrical control box through control lines.
The complete set of diesel engine water supply equipment is used for automatic (or manual) water supply systems in various enterprises, as well as for fire water supply and occasions with special requirements
