Description

Submersible pump

The utility model relates to a kind of submersible pump.

For the efficient, the water lift lift that improve submersible pump, people have adopted the submersible pump of the pump type that utilizes reciprocating motion of the pistons, and the pump of this kind form also has little, the lightweight advantage of volume.But this pump exists shortcoming also clearly, and promptly piston is because high-frequency motion causes working life short, and the bore seal of pump is unreliable to cause the electrical appliance part short circuit of making moist easily.These drawbacks limit applying of this pump.

The purpose of this utility model just is to provide a kind of and keeps the advantage of said structure pump and have long service life, the non-damageable submersible pump of electrical appliance part.

The purpose of this utility model is achieved in that it is mainly by upper pump seat, following pump seat, decide magnet, moving iron core, vibrating shaft, piston, one-way valve, Sealing is formed, by iron core line pack decide magnet and lighting outlet is installed in the pump chamber of upper pump seat, the termination, lower end of following pump seat is provided with water intake and one-way valve is housed, moving iron core is installed in decides the magnet below, the bottom of moving iron core is connected with vibrating shaft, the other end of vibrating shaft is connected with the piston of profile for dish, vibrating shaft is with stuffing box gland outward, the upper and lower end face of stuffing box gland is rubber seal ring, vibrating shaft just passes from the sealing ring hole does motion up and down, moving iron core can contact with upper sealing ring when vibrating shaft drops to lowest order, and piston can contact with lower sealing ring when vibrating shaft rises to highest order.For making the integral pump compact structure, can utilize upper sealing ring simultaneously upper and lower pump seat inner chamber to be separated.

The principle that the utility model is finished goal of the invention is: produce alternating magnetic field when iron core line bag and power connection, thereby iron core is driven by vibratory shaft drive piston to pump, when piston rises, in the pump housing, produce negative pressure, make water from entering the pump housing by one-way valve, the water that will enter down when piston descends in the pump seat is pressed into the outlet pipe discharge.In general, because when vibratory shaft moves up and down, the pump housing can produce frequent impact force to piston, thereby can make the piston fatigue damage, for avoiding the generation of this phenomenon, when making reciprocating motion of the pistons, the structure of the utility model design contacts with upper and lower seal ring that rubber is made, play sufficient buffer function, thereby can prolong the working life of piston effectively to the piston off-load.And designed stuffing box gland has the effect of off-load do except making upper and lower seal ring, can also play twice sealing and stop water and bleed and produce ill-effect in the electrical equipment of upper pump seat.

For the intensity that can guarantee seal ring makes the pump body structure compactness simultaneously, strengthen off-load ability to the vibrations part, its thickness of the part of upper and lower seal ring in stuffing box gland is greater than the thickness at other position of seal ring.Can also in upper and lower seal ring, imbed metal insert.

In order to guarantee the intensity of piston, piston is formed by stacking relatively by two dish-shaped rubber body.Plunger designs is become dish, not only can guarantee the intensity of piston but also can make the piston edge produce distortion and the pump housing fully identical.

In order to make the pump structure compactness, be equipped with passage on the upper and lower pump seat sidewall, the passage of upper and lower pump seat is to being connected into outlet pipe, and its water intake is positioned at the bottom of pump seat down, and water outlet is positioned at the top of upper pump seat.

The utility model with existing technology relatively, it is except having efficient height, the water lift lift is big, volume and weight is little advantage, structure is compact more, seal more reliable, not moisture-sensitive damage of electrical equipment; Particularly, therefore can increase the service life significantly because the force-bearing situation of piston is improved.

Below by way of embodiments and drawings the utility model is further described.

Fig. 1 is the example structure schematic representation.

Wherein: 1, upper pump seat; 2, decide magnet; 3, triple core wire lighting outlet; 4, moving iron core; 5, stuffing box gland; 6, dish-shaped piston; 7, vibratory shaft; 8, bolt; 9, one-way valve; 10, following pump seat; 11, outlet pipe; 12, go up packer ring; 13, metal insert; 14, lower seal rubber ring; 15, outlet pipe water intake; 16, pump water inlet mouth; 17, outlet pipe water outlet.

Referring to accompanying drawing, upper pump seat 1 internal fixation is sealed and installed with the iron core line bag as deciding magnet 2, triple core wire lighting outlet 3, and the single line of triple core wire lighting outlet 3 is a ground wire, and in addition two one ends join with the line bag, during the other end use and 220V voltage join; All offer a pipeline that forms water pipe 11 after involutory on upper pump seat 1 and following pump seat 10 sidewalls.Upper and lower pump seat 1,10 junction points are provided with Sealing 12, last Sealing 12 plays the separated effect of inner chamber with upper and lower pump seat 1,10, both prevented down that the water in pump seat 10 chambeies is seeped in the inner chamber of upper pump seat 1, prevented down that again the water in pump seat 10 chambeies is penetrated into outside the pump.The top of last seal ring 12, it is the below of upper pump seat chamber magnet 2 decided at the higher level but not officially announced, moving iron core 4 is installed, a vibratory shaft 7 vertically is equipped with in moving iron core 4 belows, vibratory shaft 7 the other ends are installed the central thick thin piston 6 that is formed by two involutory backs of dish-shaped rubber body all around, there is the stuffing box gland 5 that is enclosed within outside the vibratory shaft 7 piston 6 tops, the upper-end surface of stuffing box gland 5 promptly is a upper sealing ring 12, upper sealing ring 12 correspondences are embedded with metal insert 13 at the binding site of upper and lower pump seat 1,10 housings, play a part fixing and the enhancing seal ring.The lower end surface of stuffing box gland 5 is also by lower sealing ring 14 sealings, vibratory shaft 7 passes from the ring hole of upper and lower seal ring 12,14, the Design of length of vibratory shaft 7 becomes when vibratory shaft 7 drops to lowest order can make iron core 4 touch upper sealing ring 12, when vibratory shaft 7 rose to highest order, piston 6 can touch lower sealing ring 14.Upper and lower seal ring 12,14 towards stuffing box gland 5 inner chambers one towards the chamber a projecting inward part.The below of following pump seat 10 is water intakes 16 of pump, and water intake 16 places are equipped with one-way valve 9 by bolt 8.

When iron core line bag 2 and power connection, produce alternating magnetic field, thereby iron core 4 is driven by vibratory shaft 7 drive pistons 6 to pump, like this when piston 6 rises, in the pump housing, produce negative pressure, make water enter the pump housing from the following water intake 16 of pump seat 10 bottoms by one-way valve 9, the water that will enter down when piston 6 descends in the pump seat 10 is pressed into outlet pipe 11 and from water outlet 17 discharges from water intake 15.Contact with lower sealing ring when piston moves upward, impact force is cushioned, and when piston moved downward, moving iron core contact with upper sealing ring, produced buffer function, thus avoid piston directly and the pump housing collide effectively to the piston off-load working life of prolongation piston.
