XBD-ISG

Product introduction:

The XBD/G-HRZL type axial flow deep well fire pump (long-axis deep well fire pump, vertical axial flow deep well fire pump, electric vertical long-axis turbine fire pump, diesel engine deep well fire pump) produced by Shandong Hairui Zhonglian Fluid Technology Co., Ltd. is based on the safety, reliability and performance of the original HRZL/x vertical long-shaft pump. The vertical long-shaft fire pump is optimized and designed, which is especially suitable for fire-fighting water supply in workshops and plants of industrial and mining enterprises. The performance and technical conditions of the pump meet the requirements of the newly promulgated GB6245-2006 "Fire Pump" standard. The product has been tested by the National Fire Protection Equipment Quality Supervision and Testing Center, and has passed the Shandong Provincial New Product Appraisal, and has obtained the Shandong Provincial Fire Protection Product Recognition Certificate. Obtained CNCA-C18-03:2014 "Compulsory Product Certification Implementation Rules Fire Extinguishing Equipment Products", CCCF-MHSB-08 "Mandatory Product Certification Implementation Rules Fire Extinguishing Equipment Products Fire Water Supply Equipment Products (1) " and other fire inspection reports.

Advantages:

1. Introduce the advanced water conservancy model and mechanism design of American companies, adopt multiple new processes such as Ashland process knowledge, epoxy coating of blade runner parts, etc., and use imported human-oriented bearings for parts selection to reduce bearing loss, which can withstand 120 degrees High temperature; and German Iger Bergman mechanical seal, durable and anti-acid and alkali, high efficiency and long service life.

2. The sand throwing ring device is adopted, and the labyrinth structure prevents the sand from entering the bearing

3. The stainless steel runner impeller with non-welded integrated casting is adopted, and the anti-winding design is non-clogging; the stainless steel pump shaft is finely ground by the fine car, and the radial runout of the shaft is controlled within the American standard of 0.13mm. The pump runs smoothly and has low noise.

4. Select various grades of stainless steel corrosion-resistant materials such as QT450 ductile iron and HT250 to meet various special working conditions and technical requirements of users.

5. The product has high efficiency, the pump head is completely immersed in the liquid, and there is no self-priming time. When the pump is started, the water supply is pressurized synchronously;

6. The pump impeller is immersed in water, and it can be started directly without bottom valve, water diversion and shaft vacuum, which is very convenient and reliable; 3. It is directly installed on the pool, and only two support beams and channel steel beams can be supported and fixed., no suction pipe;

7. The maximum diving and water absorption height of the pump can reach about ten meters. The vertical structure covers a small area and less infrastructure investment.

8. The submerged length can be customized according to the depth of the pool to ensure that the lowest water level can be drawn.

Working principle and structure description

The working principle of the pump: the motor drives the impeller working under the liquid to rotate through the shaft. After the fluid obtains energy through the impeller, it changes the direction through the space guide vane, rises vertically along the flow channel between the inner and outer pipes, and changes to the horizontal direction through the water outlet elbow. Flow out.

The pump is composed of two parts: the central rotating body and the pump body. The rotating body part is composed of an impeller, a shaft, a sleeve-type rigid coupling (coupling and coupling), a bearing, an elastic pin coupling, etc. The pump body part is composed of a filter screen, a space guide vane, an outer tube, an inner tube, a rubber bearing frame, a base, a water outlet elbow, a bearing body, a motor base, etc.

The entire part of the pump is connected with the water outlet elbow and fixed by the baseplate. The double rolling bearings above the rotating body part and the intermediate guide bearing part are connected with the water outlet elbow and fixed by the baseplate. The double rolling bearings above the rotating body part, the intermediate guide bearing part and the lower guide bearing part in the space guide vane are supported. At the same time, clean lubricating water is injected through the lubricating water nozzle on the side of the packing box (the inner tube can be cancelled when the medium is clear water), and the flow channel area between the inner tube and the shaft is continuously lubricated and cooled. The guide bearing (PFC).. This is the key to the normal operation of the vertical long shaft pump when conveying harsh working conditions such as solid particle medium.
