Abstract
The utility model relates to a double-suction type geothermal pump assembly which is characterized in that a water injecting aperture is opened on the outer wall of a mixed flow knot, and the water injecting aperture is communicated with a guiding gutter of the lower pump body, then the guiding gutter is entered in a generator on the bottom portion of the generator through a guide conduit, further a subsidiary blade is installed on a pump shaft in a connecting knot. The utility model has the advantages of reasonable structure, convenient use and simple technique, further the self cooling of the generator is guaranteed. The dirt in the generator is purified by the double-suction type geothermal pump assembly which is a novel double-suction geothermal pump.
Description
Technical field
The utility model relates to the water pump field, especially a kind of double suction type terrestrial heat pump assembly.
Background technique
Existing terrestrial heat pump, because motor self needs from cooling, and existing cooling water-filling in motor just, awfully hot underground, this mode is the cooling that can not guarantee motor self.And, because the water self that charges into motor can have the grinding between impurity and motor shaft, can produce some dirty dirt and even metal impurities, influenced the proper functioning of motor.In addition, terrestrial heat pump can produce the pump housing when in place, influenced the normal use of terrestrial heat pump.
Summary of the invention
The purpose of this utility model is to overcome the prior art deficiency, provides a kind of structure more reasonable, can effectively guarantee the cooling certainly of motor, and can purify the double suction type terrestrial heat pump assembly of motor internal dirt.
The purpose of this utility model is achieved in that
Have water injection hole on mixed flow joint outer wall, this water injection hole is communicated with the lower pump body water chute, and this water chute enters by conduit in the motor of motor bottom, connects on the pump shaft in the joint attached impeller is installed.
Described attached impeller enters lower pump body by the guide hole of water inlet joint; In motor bottom the deploying type blade is installed, and correspondence is equipped with two upper saw pulleys between the deploying type blade; Motor carries out end face seal with the water inlet joint; One-way spiral type filter screen, vortex type gyro device, permanent-magnetic clamp between motor bottom and deploying type blade are equipped with a leather cup in vortex type gyro device bottom.
Advantage of the present utility model and good effect are:
Employing is provided with water filling hole and attached impeller is installed, and realizes the mode of the cooling water of injection in the self-loopa cooling of motor internal, can guarantee that the cooling water in the motor does not have temperature rise; In addition, deploying type blade and upper saw pulley are installed, prevent that the pump housing from producing in motor bottom; Adopt one-way spiral type filter screen, vortex type gyro device, permanent-magnetic clamp, leather cup between motor bottom and the deploying type blade, realize the filtration of dirt dirt and metal impurities.The utility model is rational in infrastructure, and is easy to use, and technology is simple, is a kind of novel double suction terrestrial heat pump.
Description of drawings
Fig. 1 is a general structure schematic representation of the present utility model;
Fig. 2 is a left view of the present utility model;
Fig. 3 is that the utility model A-A is to sectional view.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:
This terrestrial heat pump unit by the dual-purpose joint 1 of sucking-off, upper pump casing 3, mixed flow joint 7, lower pump body 8, water inlet joint 10, connect joint 13, motor 14 constitutes and by bolt 25 linking together with upper member.On the dual-purpose joint of sucking-off, be shaped on water intake 26, also be shaped on water intake 24, form the double suction function at the water inlet joint.Impeller 4 and stator 5 all are installed in lower pump body and the upper pump casing, and in the present embodiment, the impeller of upper pump casing and lower pump body and stator are two groups and opposed installation.Be sealed with sealing bolt 6 having on the mixed flow between lower pump body and the upper pump casing joint outer wall on water injection hole and its, this water injection hole is communicated with lower pump body water chute 9, and this water chute enters in the motor of motor bottom by conduit 15.Being connected on the pump shaft 2 in the joint between water inlet joint and the motor is equipped with attached impeller 12, and motor seals by sealing 11 with the end face seal of water inlet joint.
The cooling water that enters motor enters lower pump body by the water chute that attached impeller, water inlet save, and is recycled in the motor through conduit again.
In motor bottom deploying type blade 21 is installed, correspondence is equipped with two upper saw pulleys 22 between the deploying type blade.One-way spiral type filter screen 16, vortex type gyro device 17, permanent-magnetic clamp 18 also are installed between motor bottom and deploying type blade, in the leather cup overcoat 23 of vortex type gyro device bottom, a leather cup 20 are installed.One buffer disc 19 is installed between leather cup overcoat and permanent-magnetic clamp.
The working principle of this model utility is:
At first in motor, inject cooling water, be screwed into the water filling bolt by water filling hole; Then unit is put into well,, can set upright unit, cushion and prevent to block by buffer disc by the guiding and the deploying type blade of upper saw pulley.When extracting geothermal water, cooling water enters lower pump body by attached impeller, enters motor after the cooling, can make motor keep good working order; The foreign material that the impurity of cooling water and grinding back produce enter in the leather cup by vortex type gyro device, and ferrormagnetic substance is adsorbed by permanent-magnetic clamp, and one-way spiral type filter screen can prevent that floating dirty dirt from entering motor internal.
Geothermal water enters upper pump casing and lower pump body by two water intakes, through the supercharging of impeller, stator, enters the mixed flow joint along the upper pump casing tank, pumps through the dual-purpose joint of sucking-off.
