XBD-HL tangent constant pressure fire pump

XBD-DL Vertical Multi stage Fire Pump Product Overview

XBD-DL vertical multi-stage fire pump is used for conveying clean water without solid particles and liquids with physical and chemical properties similar to water. It is mainly used for pressurized water supply in fire protection system pipelines, and can also be applied to industrial and urban water supply and drainage, high-rise building pressurized water supply, long-distance water supply, mining and heating, bathroom, boiler cooling and heating water circulation, pressurized air conditioning refrigeration system water supply, and equipment matching.

The performance and technical conditions of the XBD-DL fire pump assembly meet the requirements of the newly issued national standard GB6245-1998 "Performance Requirements and Test Methods for Fire Pumps". The product has been tested and qualified by the National Fire Equipment Quality Supervision and Testing Center and has obtained the Shanghai Fire Product Accreditation Certificate. Pu Lang Pump Industry specializes in the production and sales of XBD-DL vertical multi-stage fire pumps

XBD-DL vertical multi-stage fire pump product features

1. Compact structure, small volume, and beautiful appearance, its vertical structure determines a small installation area, and its center of gravity coincides with the center of the pump foot, thereby enhancing the operational stability and service life of the pump.

2. Smooth operation, low noise, and high concentricity of components.

3. Adopting advanced hydraulic models, with high efficiency and excellent performance.

4. The shaft seal adopts high-quality mechanical seal, which has the characteristics of wear resistance, no leakage, and long service life.

5. The inlet and outlet of the pump are on the same horizontal axis and have the same diameter specifications, making it easy to connect pipelines and facilitate loading and unloading. 6. Easy to maintain, no need to disassemble the pipeline, just remove the pump cover nut, take out the motor and transmission components for maintenance.

Application of XBD-DL vertical multi-stage fire pump product

Mainly used for transporting clean water without solid particles and liquids with physical and chemical properties similar to water, mainly used for pressurized water supply in fire protection system pipelines

Service conditions for XBD-DL vertical multi-stage fire pump

1. The medium used should be similar to water, with a kinematic viscosity of<150mm2/s, no hard particles, and no corrosive properties;

Structural Description of XBD-DL Vertical Multi stage Fire Pump

1. The pump has a compact structure, small volume, beautiful appearance, small footprint, and saves construction costs;

2. The suction and outlet of the pump are on the same centerline, simplifying the connection of the pipeline;

3. According to the actual situation, the inlet and outlet of the pump can be assembled in different directions of 90 °, 180 °, and 270 °;

4. According to the actual situation, the outlet of the pump can be assembled into 1-5 outlets to meet different head requirements on the same pump;

Starting, Operation, and Shutdown of XBD-DL Vertical Multi stage Fire Pump Unit

1. The pump unit is used in suction applications, where the inlet is under negative pressure. Water should be injected into the pipeline or a vacuum pump should be used to fill the entire pump and inlet pipeline with water Note that the inlet pipeline must be sealed There must be no air leakage. (It is strictly prohibited to start without water before starting, and water must be added before starting)

2. Close the gate valve and pressure plug on the outlet pipe To reduce the starting current.

3. Rotate the rotor a few times by hand to lubricate the bearings and check for any damage to the impeller and seal inside the pump during operation. If it cannot rotate, check for any rubbing It should not be started Until the cause of the malfunction is identified.

4. Test start, the motor direction should be consistent with the arrow on the pump Open the spinning base.

5. When the rotor reaches normal operation The pressure gauge displays the pressure inch Gradually open the outlet gate valve and adjust it to the desired operating condition.

Operation

1. When the pump unit is in operation Attention must be paid to observing the instrument readings Try to operate the pump near the flow head specified on the nameplate Strictly prevent high traffic operation.

2. The motor current value should not exceed the rated current during scheduled inspections.

3. The bearing temperature of the pump unit shall not exceed 75 ℃.
