Improve the self-priming non-clog sewage pump self-priming ability and the self-priming performance measures

ZW self-priming non-clog sewage water pump is also called the solid-liquid pump or impurity pump. This series of pump hydraulic design is unique, the impeller is in single leaf indoor, connected to the impeller chamber is pressurized water chamber, when the impeller rotates, the liquid in the pump produce strong axial eddy current effect, make the import vacuum, export to produce lift. Thus impurities can be from a pressurized water chamber, so its port is completely open, the other self-priming sewage effect is incomparable. Installation and use, easy to move, stable performance, repair rate is extremely low, favored by the users.

improve self-priming non-clog sewage pump self-priming performance measures:

1) Increase export maximum rotational speed and impeller impeller blade outlet width, the impeller outlet largest circumferential velocity can increase through enlarging the impeller impeller speed method. But the earth to ensure the increase in export maximum rotational speed and impeller impeller blade outlet width will change the basic performance parameters of the pump flow, head, etc. So should meet the needs in the capacity and head of the pump down the premise of appropriate increase export maximum rotational speed and impeller blade impeller outlet width.

( 2) Water content and the self-priming performance relationship: when water content increases, the pump self-priming height increased significantly, but the water yield is too big, will slow down the process of gas discharge, which can increase the self-priming time. So when time self-priming height but high demand is not too strict, can increase the pump of water, which increase the liquid storage chamber volume, but relatively strict with self-priming time, shall reasonably determine the size of the liquid storage chamber.

( 3) Reflux hole area and the self-priming time and the relationship between the self-priming height: within critical backflow hole area, when the reflux hole area increases, the self-priming time reduced, and the self-priming height decreases. So when the self-priming time requirements are strict requirements and self-priming height is not high, can increase the area of reflux hole appropriately, on the contrary, should be properly reduce reflux hole area.

( 4) Set the gas-liquid separation accelerating device can accelerate the separation of gas and liquid, which can shorten the self-priming time, accelerate the simplest gas liquid separation device for gas-liquid separation chamber in baffle type. As shown in figure 1. In gas-liquid separation chamber in baffle type of self-priming height have little impact. So, as long as the structure, should be allowed when the gas-liquid separation chamber set baffle to accelerate the separation of gas and liquid, shorten the self-priming time.

improve self-priming non-clog sewage pump self-priming ability:

1) Self-priming non-clog sewage pump suction pipe end suction bottom valve installation. Suction bottom valve is actually a check valve, it ensure that water can only be by the pool in suction pipe and cannot put back the clock, so if the suction tube filled with water, although the pump axis elevation above the pool water level, but with the role of absorbing water bottom valve, the suction tube of water will not flow into the pool, can make the suction tube has been filled with water, ensure the pump automatically, rapid start. The reliability of this way of absorbing water is affected by bottom valve water quality, for example, closed lax, leaks, the suction tube of water can flow slowly sink, time grew, the suction tube, there is no water, causing the pump starts still need artificial irrigation ( The public number: pump pipe home) 。

( 2) Self-priming non-clog sewage pump to reduce water pipe bend, gap between height and horizontal distance.

( 3) Self-priming non-clog sewage pump set before the pump suction tank. This way needs to be on the water pump suction pipe to set up a water tank, pump before the first run, the tank should be artificial filled with water, after the first run to stop, because of the water tank inlet pipe height above the tube surface height, although the water level below the height of the tank water in tank, tank of water will not flow back, into the pool, so the water tank can store a certain amount of water, and because of the water tank outlet pipe ( The pump suction pipe) Height below the tube surface height, so to make sure that the suction tube filled with water pump, pump running again, the water in the pitcher is draining pump, negative pressure inside the tank, the water in the pool under the action of atmospheric pressure, added water tank, by absorbing water tank inside the pool.

( 4) Self-priming sewage pump set vacuum pump in the pump suction pipe on the road, before starting the pump, vacuum pump to start, first make the pump suction tube filled with water first, ensure the water pump automatically, rapid start. This way of absorbing perfect automatic control system is needed to guarantee the normal work.

The use and installation of submersible pump is compared with most other systems for managing the pool cover drain pump effectively and no doubt submersible pump have won the race so many times.
