Abstract
A motor and a diving tubular pump apparatus with a front motor segment belong to the technology field of a tubular pump. The diving tubular pump apparatus with a front motor segment comprises a water inlet channel, a water pump impeller chamber, water pump impellers and a water outlet channel which are connected in sequence. The diving tubular pump apparatus with a front motor segment is characterized in that the motor segment is arranged between the front of water pump impeller chamber and the water inlet channel. The motor segment comprises a motor and a motor segment housing, wherein the motor is arranged in the motor segment housing, and the motor is connected with the motor segment housing through a metal backing sheet. The motor segment housing is formed by the welding of steel plates, the water inlet side of the motor segment housing is connected with the water inlet channel, and the water outlet side is connected with the water pump impeller chamber. According to the utility model, the structure is reasonable and simple, the conception is novel and ingenious, the horizontal length of the pump is largely shortened, the construction investment of a pumping station is minimized, and the defects of the prior motor and the diving tubular pump apparatus with a back motor segment are overcome. According to the front arrangement of the motor segment, current adjustment is carried out to a water flow field through the motor segment, the motor segment plays the effect of a water inlet channel, and a better water flow state is obtained.
Description
Technical field
The utility model relates to the structural type of tubular pump or through-flow pumping plant, and particularly the layout of the motor of submersed three-flow pump-unit and motor section belongs to the tubular pump technical field.
Background technique
The submersed three-flow pump-unit is the integrated pump-unit pattern of a kind of horizontally-mounted novel electromechanical; Adopt submersible motor; Have that runner is straight, hydraulic performance is excellent and simple in structure; Advantages such as convenient for installation and maintenance, construction investment province are improved and be used widely in aspect such as agricultural drainage and irrigation in water resources allotment, urban flood defence, water environment, and application prospect is very wide.
The submersed three-flow pump-unit of using at present all is installed in (see figure 1) between water pump diffuser and the outlet passage of water pump section with submersible motor and motor section.But the pump-unit of this pattern because the diameter of motor section is constant, needs after it, to set out in addition water flow passage; So that the smooth-going diffusion of current, reclaim the kinetic energy that current had; Cause the horizontal length of entire pump device very long, increased the construction investment of pumping plant, have influence on further and apply.
The model utility content
The purpose of the utility model is exactly the deficiency to above-mentioned existing technology, provides a kind of motor and motor section preposition submersed three-flow pump-unit, utilizes motor section that the current adjustment is carried out in the water inlet flow field, and the effect that improves water inlet flow channel obtains better water inlet fluidised form.
The purpose of the utility model is to realize like this; The submersed three-flow pump-unit that a kind of motor and motor section are preposition; Comprise water inlet flow channel, water pump vane chamber, water pump diffuser, outlet passage and motor section; Water pump vane chamber, water pump diffuser, outlet passage are installed connection successively, it is characterized in that said motor section is arranged on before the water pump vane chamber and between the water inlet flow channel.
Said motor section comprises motor and motor section shell, and motor is arranged in the motor section shell, and motor is connected with the motor section shell through the metallic support sheet.
Said motor section shell is made up of the steel plate welding, and its influent side and water inlet flow channel join, and water outlet side and water pump vane chamber join.
Be provided with fair water cone behind the said water pump diffuser, the metal shell and the outlet passage of water pump diffuser join.
The utility model is rational in infrastructure simple, novel ingenious, can shorten horizontal length, the minimizing pumping plant construction investment of pump-unit greatly, has overcome the defective of the rearmounted submersed three-flow pump-unit of motor and motor section, and application prospect is more wide.Motor and motor section are placed between water pump diffuser and the outlet passage (postposition) to be changed into and is placed on (preposition) between the place ahead, water pump vane chamber and the water inlet flow channel.Motor section is rearmounted to be with preposition difference: when motor section is rearmounted, because the diameter of motor section is constant, so can not play the effect of divergent flow, need the fully recycle-water energy of flow of a complete outlet passage be set at the back at it; When motor section was preposition, motor section capable of using was carried out the current adjustment to the water inlet flow field, plays the effect of water inlet flow channel, not only can significantly reduce the length of water inlet flow channel, but also obtain better water inlet fluidised form.
