Tangent tangent pump fire pump XBD yes, yes military to civilian products. XBD fire pump running tangential outlet pressure when gently lift almost constant flow rate changes, especially for variable flow regulator requirements in the fire, there are direct-coupled horizontal and vertical direct connection of two structurally. XBD fire pump tangent entire series are used Y2 acceleration axis motor, impeller radial open, no mouth ring, does not rust, and therefore particularly smooth and reliable operation 2 tangent tangent pump now pumps for life now renamed the converter regulator pump. Using tangent pump to the fire to bring a corresponding change to the water supply network, are: standard relates to the main content fixed fire pumps as follows: (1) fire pump, code-named XB. (2) The prime mover features a motor, three kinds of gasoline and diesel engines, code-named D, Q, C. Motor driven fire pump codenamed XBD. (3) pump nominal flow Qn of 5,10,15,20,25,30,35,40,45,50,55,60,65,70,75,80,85,90,95,100,105 , 110,115,120,125,130,140,150,160,180,200L / s. (4) pumps rated pressure Pn of 0.3MPa ~ 3.0MPa. (5) When the suction deep 0m, should meet the rated flow and pressure rating requirements. 6m deep when the suction pressure of the rated pressure, flow rate should be not less than 50% of the rated flow. (6) The fire pump flow cross-section of the media should have corrosion resistance; should have good vacuum sealing performance. (7) the engine should be good at room temperature startup performance, should ensure a smooth start within 5s, in the 20s, should enable the lead after the Sheung Shui fire pump reach the rated operating conditions, room temperature refers to the 5 ℃ ~ 35 ℃. (8) The pump pressure test at 1.5 times the maximum working pressure, continued 5min. During the experiment should not affect the performance of the pump casing deformation and cracks and other defects. (9) The pump casing made of cast iron, cast aluminum, copper, other flow components made of stainless steel, bronze or aluminum alloy corrosion resistant material high pump may not be anti-corrosion test. (10) The pump should be 10min overload test. During the test, pumps should be working properly, no excessive vibration, oil spills, leaks and other phenomena. 3 tangent pump Inevitable building water supply and drainage project using the pump, are common pump. Whether for domestic water supply, or for the production of water, or water used for fire; and whether it is to the water tanks, water pressure tank or to, or directly to the water supply facilities, covers all using a common pump. In fact different purposes, pumps requirements of different occasions is not the same, you should choose the appropriate pumps, general pumps to pumps direction according to their different circumstances is inevitable. 4 tangent pump characteristics in line with national standards for fire pump performance requirements, successfully developed products by the National Fire Equipment Quality Supervision and Inspection Center, the indicators qualified, and the market has been applied in the project when pushed tangent pump. Tangent pump provides technical parameters and application conditions by the China Architecture Design and Research Northwest Aerospace Corporation Development Research Institute 11. At that time the focus is on the design of a flow - lift curve approaching a smooth straight line pumps can be used for high-rise building fire water supply design in the most ideal pumps to solve overpressure generated when the fire pump low flow or zero flow operation, but while also taking into account other requirements for fire pumps. So tangent pump flow parts made of stainless steel and aluminum alloy, pump and motor coaxial straight, with a compact, small footprint, smooth operation, reliable mechanical seal, low noise, high reliability, easy maintenance, long life and so on. Tangent horizontal centrifugal pumps, its greatest feature is the flow - lift curve is very flat. The maximum flow rate when the pump flow rate within the range from zero to the desired, change its lift within 5%. Driving the pump motor is a normal motor, without shifting. It effectively solves the water pressure changes during fluctuations in flow rate and low flow severe overpressure problems. Compared with multiple pumps operating in parallel to reduce the number of pumps, reduced footprint, easy operation and management; compared with Variable Speed ??Pump, saving investment, easy management, with more advantages, it is to solve the overpressure more perfect approach. 5 tangent pump Sort by category "fire protection design of tall buildings" of the building, building height regulations, indoor fire flow, etc., tangent pump is currently divided into three major series: the first series to meet building 24m ~ 100m , fire flow 0L / s ~ 20L / s building fire water requirements; a second series to meet building 24m ~ 100m, fire flow 0L / s ~ 30L / s of building fire water requirements; third Series meet building 50m ~ 100m, fire flow 0L / s ~ 40L / s of building fire water requirements. Three series of fire hydrant water supply system and the flow rate are automatic sprinkler system independent, separate pumps as a base point. When the two systems share water pumps, fire flow of the two systems require the appropriate overlay. Therefore, the need to increase the current series of new varieties. 6 tangent pump and pump the difference between life tangent pump fire pump is different from life, except that: (1) Fire flow is relatively regular. Fire Hydrant System to 5L / s increments for the series. Sprinkler system corresponding to the light danger level, the danger level, a serious risk level of the flow value is incremented. (2) The fire pump is used to ensure the fire water quantity and pressure, it comes to personal safety and property protection, must be reliable. Requirements pump rational structure, appropriate material, and high reliability. (3) fire pump generally used by the pump directly to the fire fighting equipment (fire hydrants, sprinklers) water ways. In the early fire or self-test run small flow of water in the fire according to the design development phase flow of water. When the pump flow - lift curve is steep, prone to excess pressure flow phenomenon in a small operation, which should take appropriate technical measures. (4) fire pumps for fire fighting, called for the speedy, timely and appropriate requirements fire pump water a short time, startup performance.
