Pitot tube pump, jet pump, rotary jet pump, screw pump shell, pitot tube pump, pump, bits, series production rotary jet pump is the independent research and development of enterprises. New type of rotary spray pump is in absorbing foreign similar products on the basis of the latest scientific and technological achievements, application of new special pump fluid system of science and technology, combined with the actual development of success in the application of the domestic high and new technology products and high efficiency and energy saving products, adopt the similar structure was optimized, pump small size, light weight, high efficiency and energy saving, the pump with independent intellectual property rights, has to declare the patent for utility model, pump product development center according to the needs of the market, through the unremitting efforts, has successfully developed TRJ series rotary jet pump, its technical level is a world leading level, beyond the international similar products excellent performance, fill in the blank of Chinese production into series rotary spray pump, the pump efficiency leading domestic like product from 10% to 20%.
Pitot tube rotary spray pump is a kind of small flow high lift pump, can be successfully applied to the conveying flow 0.1 ~ 160 m3 / h, lift 1600 m or less, the medium of medium condition of temperature 350 ℃ or less and pump speed in RPM, 3000-5000 growth means has frequency growth, gear box growth and belt growth is chosen.
Pitot tube pump working principle: the rotor rotate cavity (shell), in the middle of the header pipe motionless. Rotors rotating impeller into liquid with the rotor cavity, and then enter the header pipe entrance, header pipe collects the rotor cavity high kinetic energy of the liquid, the liquid kinetic energy into pressure energy output.
The pump in the field of small flow high lift is the upgrading production of reciprocating pump, multi-stage pump, mainly used in petroleum, chemical industry, chemical fertilizer, metallurgy, paper making, pharmacy, mining, carbon black and other industries.
Pitot tube rotary jet pump is suitable for processing technology of medium are: coal tar, condensate, amino acid potassium ammonium liquid, ammonium solution, potassium permanganate solution, acid, ammonia water rinses, tetrahydrofuran, methanol, sewage, ring ding sulfone, reforming generated oil, benzene, lean amine liquid, lye, hexene/hexane/isopentane/butene/a lot of process media such as butane, suitable for boiler feed water pump, circumfluence pump, tank bottom pump and so on, is to replace the pump, multi-stage pump, plunger pump of choice.
New type of rotary spray pump has the following characteristics
The rotor cavity structure of cantilever than small new, stable support to overcome the disadvantages of too much heavy rotor cantilever support is not smooth;
New structure optimization design, pump parts, less a multistage pumps and current common rotary spray pump has simple structure, installation and maintenance is very convenient, and low maintenance cost. Machine is located in the pump inlet, only seal inlet pressure, easy to implement sealing, long service life; Easy to operate, simple and feasible; Spindle out of touch with media, no sealing problem, so don't consider shaft corrosion resistance;
Due to the special structure design of the pump, the pump rotor almost do not produce axial force, fundamentally overcome a multistage pump axial force and the balance of the problem of poor; Using large amount of bearing rich and bearing external is equipped with water cooling cavity, bearing service life is long;
Growth, there are separate gear box, gear ratio is not big, the growth of body and bearing, seal, the requirement of gear is not too high, gear box easy maintenance, stable and reliable work, long service life. Using belt growth is more simple, and the cost is lower, is conducive to competition in the market;
Lift curve smooth flow, flow can range from zero to maximum flow range are operational, no minimum flow restriction, fan k 'uan wide operation. Due to the special design of the impeller, and the liquid into the rotor cavity, the impeller has a stable process in the rotor cavity, head flow fluctuation is small, the flow changes when the head is relatively small, with variable current voltage characteristics.
High efficiency, rotor cavity pump with the impeller with the spindle rotation, no multistage pump that disc friction loss, high pump efficiency, the efficiency within the scope of the small flow high lift a multistage pump, high-speed pump higher than 3 ~ 5%, belong to high efficiency and energy saving products.
Products facilitate series, can be achieved by changing the header pipe throat diameter change its flow, change the pump rotation speed or change the header pipe diffusion length (or the impeller diameter) to change the head, full range of only three basic pump (4) specifications can be achieved all series stepless modular combination of performance;
Use less maintenance costs, often only need a replacement, operation cost is low, not as much as multistage pump, reciprocating pump parts.
Manufacturing process relative to the multistage pump, reciprocating pump, the pump is simple, less components, low cost.
TRJ series: there are three basic rotary spray pump belt after growth into four high-speed rotary spray pump 75 kw or less; Gear box after growth into four; TRJ series rotary spray pump parameters: n = 2950 r/min: Q = 0.5 m3 / h ~ 28 and h = 100 ~ 300 m, 11 ~ 55 kw motor; N = 3400, 3850, 4300, 4750 r/min: Q = 0.5 ~ 160 m3 / h, h = 150 ~ 1600 m, 18.5 ~ 250 kw motor; Medium temperature is 280 ℃ or less.
