FB50-16 explosion-proof stainless steel centrifugal pump

Explosion-proof stainless steel centrifugal pumps are also supplied - Vertical stainless steel pipeline pump casing Stainless steel vertical multi-stage fire pump Product overview: This unit is a new generation of fire pumps developed based on the original vertical multi-stage pump according to the relatively new standard requirements for fire pumps Medium and low pressure fire pump products. -Vertical stainless steel pipeline pump casing Stainless steel vertical multi-stage fire pump meets the requirements of fire pumps in terms of performance, structure, materials and supporting equipment. Due to the use of excellent hydraulic models, this series of pumps can meet user requirements. The vertical pump structure has the characteristics of high efficiency and wide performance range, which can better save floor space. The use of high-quality bearings and high-quality motors make the pump run more efficiently. Safe and reliable, with low noise and small vibration, the hydraulic balance axial force is used to reduce the balance drum, which can make the operation more stable. -Vertical stainless steel pipeline pump casing The shaft seal of the stainless steel vertical multi-stage fire pump has two forms: mechanical seal and packing seal. The pump has the characteristics of inlet and outlet flange pipeline layout, high speed, and light weight. -Vertical stainless steel pipe pump casing Stainless steel vertical multi-stage fire pump is suitable for fire water supply in various occasions such as residences, hotels, office buildings, commercial buildings, factories, hospitals, etc. - Vertical stainless steel pipeline pump casing The stainless steel vertical multi-stage fire pump adopts the hydraulic model of the highly efficient and energy-saving product pump recommended by the country and is a vertical multi-stage multi-segment structure. The screw clamps the water inlet section, middle section and water outlet section together. Each stage of the water pump is equipped with an impeller and a water guide vane. The axial force is solved by hydraulic balance method. The residual axial force is borne by ball bearings and lubricated with grease. The shaft seal adopts soft packing or mechanical seal. Product execution - "Vertical Multistage Centrifugal Pump Type and Basic Parameters" standard is mainly used to suck dilute, clean, non-corrosive, non-explosive water and liquids with physical and chemical properties similar to water that do not contain solid particles or fibers. 2. Product use: D() type vertical multi-stage centrifugal pump is widely used in fire protection, domestic water supply, air conditioning unit circulation and cooling water transportation in high-rise buildings. 3. - Vertical stainless steel pipe pump casing Stainless steel vertical multi-stage fire pump Product features: Advanced hydraulic model: high efficiency, wide range. . Novel structure and reliable operation: the axial force of the balance drum is eliminated and hydraulic balance is used to completely solve the problems of the balance drum being easy to rust, seize and wear, ensuring more reliable operation. , Less operation and maintenance costs: Using high-quality mechanical seals with wear resistance, no leakage, long service life, low failure rate, and less operation and maintenance costs. . Smooth operation and low noise: The use of low-speed motor makes the pump run smoothly and with low noise. , - Vertical stainless steel pipe pump casing Stainless steel vertical multi-stage fire pump series, the vertical structure occupies a small area. 4. Technical parameters: Flow rate: Lift: - Power: - Speed: r / Caliber: - Temperature range: - + degrees Celsius Working pressure: . 5. Model meaning: #-Pump inlet and outlet diameter (.) Vertical multi-stage centrifugal pump-Flow rate (/). - The explosion-proof stainless steel centrifugal pump is one of the explosion-proof stainless steel centrifugal pumps manufactured by Shanghai Longya Pump Factory. This type of explosion-proof stainless steel centrifugal pump can pump tons of materials per hour and can pump the medium to a height that is the height of the pump. The motor power of this explosion-proof stainless steel centrifugal pump is .kW. Shanghai Tilong brand explosion-proof stainless steel centrifugal pump produced by Shanghai Longya Pump Factory. Longya brand explosion-proof stainless steel centrifugal pump is a single-stage single-suction cantilever-type corrosion-resistant centrifugal pump, which is an improved design based on the new corrosion-resistant pump. It adopts a new type of secondary impeller power shaft seal device. As shown in the figure, the suction port and discharge port are the radial sealing dead points of the suction and discharge chambers respectively. It can be seen that the theoretical discharge flow rate per revolution should be: =-(r - r) [] where - the width of the rigid support ring - the pump body Cavity radius - rigid support ring radius - theoretical volume coefficient mainly considers the impact of the ineffective sealing angle and structural size r on the theoretical flow rate. Usually the ineffective sealing angle is controlled respectively. The internal value can be obtained accurately and generally takes: -. In the design, r = r + where is the eccentricity value. Then the theoretical flow rate of the pump is: Taking into account the influence of the pump's pressure difference, medium viscosity, gap size and pump speed on the flow rate, the rated flow rate of the pump is: r = in the formula - volume coefficient pump speed and pump radial and axial direction Determination of clearance. Pump speed uses a planar peristaltic rigid support ring, so the relative sliding speed between the pump body, pump end cover and rigid support ring is related to the pump speed. Its value can be estimated: =/ It can be seen that reasonable control and reduction of pump speed It can reduce friction and power loss, extend pump service life and improve pump efficiency.
