Trash Self Priming Pump Characteristics of eu-flo pump

The TSP series Trash self-priming sewage pump is a new generation product developed by the latest technology of Domestic and foreign. The pump is single-stage, single-suction, horizontal, application for gas-liquid mixture. The rear pull structure eliminates the need to remove the pump body and piping.

The TSP series of self-priming pumps are specifically designed to handle solids-containing liquids for economical and trouble-free operation. The pump features anti-blocking, No winding, and strong sewage pass through ability. The front sealing plate of the pump is designed with a removable and clear-up hole structure to ensure quick and timely removal of strong dirt.

Structural features

  1. One-time irrigation, lifetime use: just fill the pump cavity through the irrigation hole before the first run, no need to refill after starting.
  2. The semi-open non-blocking impeller with hydraulic optimization design can pass the larger size solids and has strong sewage capacity.
  3. The connection mode of the threaded pipe without bolts greatly reduces the installation time.

4, self-priming ability: Nearly impossible sealing gap, to ensure that the self-priming height reaches nearly 8m, while running high speed, greatly shortening the self-priming time.

5, easy external adjustment: even if the gap between the impeller and the front sealing plate is increased, it can be easily adjusted by the outside to ensure stable self-suction height and performance.

  1. Quick and easy maintenance: The routine maintenance service is fast and easy to effect, thus saving time and labor. It is specially designed for the specialized sewage maintenance , and can be easily adjusted without removing the pump cover and auxiliary pipeline to ensure the pump runs at Efficiently working conditions.pump manufacturers in china|eu-flo pumppump supplier in china|eu-flo pump

Inducer Impeller Pump

 Inducer Centrifugal Pump
Inducer Centrifugal Pump

The front inducer, because the inducer has much higher cavitation resistance than the centrifugal impeller, so in some pumps with high cavitation performance requirements, the front inducer is widely used (ie, an inducer device is installed in front of the first stage impeller).

  Why does the inducer have much higher cavitation resistance than the centrifugal impeller? This is because in the centrifugal impeller, when the liquid enters the blade head, the direction should be sharply turned, the flow rate is increased, so the pressure is reduced, which is extremely It is prone to cavitation and separates the vapor from the liquid. After the initial cavitation is generated, the centrifugal impeller cannot limit its development because the flow direction of the liquid in the impeller is along the direction of the centrifugal force, and the liquid is under the action of centrifugal force. The high speed outwards, which accelerates the separation of the vapor and the liquid. However, in the inducer, this is not the case. First, the liquid does not go through the turn when entering the inducer, and the dynamic pressure drop is small, so that cavitation is less likely to occur; that is, cavitation occurs (mainly occurs at the outer edge of the inlet, because here The relative velocity is the largest), the bubble will be immediately attacked by two aspects: on the one hand, when the outer edge bubble flows to the high pressure region in the axial direction, the pressure is immediately condensed; on the other hand, under the action of the centrifugal force, the hub The liquid rushes toward the outer edge of the inducer, which also causes the bubble to condense under pressure.

  The inducer is actually an axial flow propeller, but it has the following characteristics compared with the general axial flow pump propeller:

  1. The ratio of the outer diameter of the propeller to the hub is small;
  2. The number of blades is small;
  3. The blade placement angle is small;
  4. The cascade density L/t is large.

  When the inducer works together with the centrifugal pump impeller, the lift generated by the inducer wheel pressurizes the centrifugal impeller.

  The inducer blade type has two types of flat type and curved type. The flat blade type has the same angle of the blade at inlet and outlet, and is also called the Equal pitch inducer. The inducer with a curved blade has a small angle of the blade at inlet and a large angle at outlet, that is, β1<β2, which is called an increased pitch inducer. The first flate type of inducer is often seen in cylindrical inducer, and the second curved type is often seen in tapered inducer. Compared the cylindrical inducer with the tapered inducer, the cylindrical inducer is better, the tapered inducer with higher efficiency , better cavitation resistance (because of the large outlet angle, and has a tapered shape, which is conducive to re-condensation of the bubble), and the stable operation without noise.

   General inducer:

  Length to diameter ratio hi / dt = 0.3 ~ 0.4 (dt = (d + d1t) / 2);

  Number of blade Z = 2-3;

  Cascade density L/t≈1.5 (L is the cascade length, t is the cascade spacing);

  Blade inlet edge rounding R=0.32d;

  The hub and rim shape is cylindrical or 15° tapper.

  In the power plant, the inducer is mostly used in the newly buit condensate pump. due to adopt inducer, the pump can increase speed, so that can reduce impeller Diameter and stages of the pump under the same flow rate and head. to make The condensate pump structure is simplified and in smaller size.

High Performance Balanced Pump

High Performance Balanced Pump
High Performance Balanced Pump

Higher Performanced Self-balancing horizontal multi-stage centrifugal pump impeller adopts a back-to-back arrangement to substantially eliminate the axial force, and the residual axial force is bear by a pair of back-to-back angular groove ball bearings. Because there is no balance device, that is, eight the disc friction loss no balance return loss, the pump efficiency is increased by 5-1% compared with the multi-stage pump of the same category, and the various failures of the pump caused by the failure of the balance device are completely solved. Greatly extend the life of the pump:

High-performance sealing, mark: traditional mining multi-stage pumps are filled with packing. The advantages of packing sealing can resist solid medium, but there are leakage problems in the use of engineering, mechanical seals are leak-free, but used in medium with solids. The service life is very short. our new developed mining multistage pump produced The seal used is a high-performance seal that combines the advantages of a packing seal and a mechanical seal in a medium with solids.

Long-term use without leakage, this seal is a new type of patented high-performance seal resistant to solid medium and developed by our company.

The bearing housing never enters the water. This technology is a newly developed patented technology by our company, which ensures that the pump is in use and in a static state without liquid entering the bearing housing. This further extends the bearing service life of and reduces the user’s Maintenance costs.
