FXP type new rotary jet pump is on the basis of absorbing the latest scientific and technological achievements of similar products abroad, the application of space technology in the stamping stagnation pressurization principle, combined with the domestic application field of the actual development of successful high-tech products and efficient energy-saving products, using the new structure optimization design at home and abroad, So far, it is the most simple structure, the most compact size, high pressure, stable operation of the single stage high efficiency high pressure energy-saving pump. The pump is a high-tech replacement product of reciprocating pump, multistage pump and high-speed pump in the field of low flow and high head. It is mainly used in petroleum, chemical industry, chemical fertilizer, metallurgy, electric power, paper making, pharmaceutical, food, mining, carbon black and other industries. FXP350-R05, FXP350-D12 F: leap pump industry. XP: rotary jet pump 350: pitot tube rotary diameter R: single inlet pitot tube D: double inlet pitot tube 05: pitot tube inlet diameterPower generation industry: cleaning pump, fuel pump, boiler feed water pump. Paper industry: high temperature spray, high pressure spray. Petrochemical chemical fertilizer industry: process pump, hydrocarbon liquid transport, waste liquid transport, hydrolytic feed, oil and gas mixed transport. Other industries: high pressure washing, cooling and cleaning of parts after processing of boreholes for automobile manufacturing industry; As a carbon black production line of raw oil transport; CIP high pressure cleaning system for food processing industry; High pressure cutting for copper pipe manufacturing, cleaning system before packaging; Used for aircraft tires and other automatic large washing system; Other use of vortex pump, high speed pump, small flow multistage centrifugal pump occasions. Product features high safety and reliability: FXP type new rotary jet pump rotor cavity using cantilever structure, rotor components cantilever ratio is small, stable and reliable support, to overcome the traditional structure of the rotor weight, cantilever ratio is too large. Long seal life, low maintenance costs: FXP new type of rotary jet pump structure optimization design, pump parts fewer, more than the current multistage pump and ordinary rotary jet pump simple structure, very convenient installation and disassembly and maintenance, and low maintenance costs. The machine is sealed at the pump inlet, only need to seal the inlet pressure, easy to achieve sealing, long service life; Easy to operate, simple and easy; The main shaft does not contact the medium, no sealing problem, so do not consider the corrosion resistance of the shaft;

Long bearing life: FXP type new rotary jet pump because of the special structural design of the pump, the pump rotor almost does not produce axial force, fundamentally overcome the multistage pump axial force is large and difficult to balance. Bearing adopts imported bearings, bearing lubrication adopts oil bath lubrication, bearing selection rich quantity, bearing is equipped with cooling chamber, bearing long service life; Good stability: FXP type new rotary jet pump growth, there is a separate gear box growth, gear ratio is not big, the growth box and bearing, seal, gear requirements are not too high, gear box easy to maintain, stable and reliable work, long service life. ≤75kW can also use the belt growth is more simple and easy, and the cost is relatively low; Easy flow regulation: FXP new rotary jet pump has a smooth flow head curve, can be operated from zero flow to maximum flow range, no minimum flow limit, wide operating range. Because of the special design of the impeller, the liquid flows through the impeller into the rotor cavity, in the rotor cavity has a stable process, flow head fluctuation is small, flow change when the head change is relatively small, with variable flow pressure stability characteristics, liquid pressure output without pulsation. High efficiency and energy saving: FXP type new rotary jet pump high efficiency, pump rotor cavity with the impeller along with the main shaft rotation, no multistage pump as the disk friction loss, pump efficiency is high, its efficiency in the small flow high head range than the multistage pump, high speed pump is more than 3~5% higher, belongs to energy-saving products; Strong versatility: FXP type new jet pump cavitation allowance is low, different from the general centrifugal pump, speed increase and NPSHr value does not increase, can handle the entrain 15% gas liquid, can be steam liquid mixed transport;The product is easy to serialize: FXP new rotary jet pump can change the flow rate by changing the diameter of the throat of the collector pipe, change the pump speed or change the length of the diffusion section of the collector pipe (or impeller diameter) to change its head, the whole series of only three basic pumps can realize the stepless modular combination of the whole series of performance; Less operation and maintenance costs: FXP type new rotary jet pump usually only need to change the machine seal, low operating cost, unlike multistage pump, reciprocating pump as many vulnerable parts, manufacturing and processing relative to multistage pump, reciprocating pump, high-speed pump is simple, fewer parts, low cost.

Figure shows rotary jet pump essence. The shell is composed of a rotating circular shell, the center of the shell is equipped with a fixed airfoil collecting tube, namely the pitot tube, from which the liquid enters the shell along the axial direction. At the outer edge of the shell, the liquid increases its pressure and velocity due to centrifugal force. The collector nozzle has an opening in the direction of rotation and is placed close to the outer wall of the shell, so that most of the kinetic energy of the liquid can be converted into static pressure. The fluid is then returned to the center of the pump through a hole in the support arm of the collector and to the discharge pipe. The cross section of the collector tube is shaped like a wing in order to reduce the resistance of the high-speed rotating fluid medium. By using this principle, a relatively high outlet pressure can be obtained at a single stage. The pump produces a non-pulsating flow and has a stable NPSHR curve over a wide flow range. The pump collector tube is made of high-tech aerospace materials, wear resistance, corrosion resistance and high temperature thermal expansion coefficient is small, high safety and reliability, its advantages: under the same conditions of use, than positive displacement pump or multistage centrifugal pump size is small, low cost, with smooth flow (namely, the head curve is flat, has the characteristics of variable flow stability), pump outlet pressure without pulsation phenomenon.
