Abstract

A novel submersible aerator motor with a rod device comprises a motor housing 4, a front end cover 1, a back end cover 2, a back cover 5, a petrol cover 6, a motor rotor 7, a negative pressure chamber 8 and a rod 11. The front end cover, the back end cover and the back cover are all provided with rod holes through which the rod is tightly fixed. In the fixed state, planes of the front end cover and the back end cover with a closing face of the motor housing are in the same plane. When the petrol cover is equipped at a port of the motor housing, a seal ring on the petrol cover contacts the port plane of the motor housing, and when the back cover is equipped at the port of the motor housing, a seal ring on the back cover contacts the port plane of the motor housing, thus the sealing effect is obvious. The front end cover and the back end cover of the utility model are unexposed, thus tending not to rust and not to pollute natural environment. The submersible aerator motor with a rod device of the utility model has a beautiful shape.

Description

The novel submersible type aerator motor of band pull rod device

The utility model belongs to the parts that use on electromechanical equipment----the submersible type aerator, relates in particular to a kind of novel submersible type aerator motor with pull rod device.

The submersible type aerator is widely used in aquaculture, highly effective oxygen dissolving is in water, the fishes and shrimps that are beneficial to large-area high-density are raised, the oxygenation function makes Chi Shuizhong contain the required oxygen of enough aquatic products growths, shorten the culture-cycle, simultaneously since water quality can decompose its most of harmful substance by oxygen and be purified, reduce the generation of disease to greatest extent, existing aerator, motor is hung by floating drum and air inlet pipe, the motor high speed rotating that pulls the plug, drive propeller negative pressure is found time to form by negative pressure chamber, link to each other with emersed air inlet pipe with ring flange through isocon again, by the air of negative pressure in air inlet pipe suction atmosphere, return through time isocon and enter negative pressure chamber, whole pond oxygen is evenly distributed after propeller hollow space suction spirt is gone into Chi Shuizhong.

As shown in Figure 1, existing motor is made up of motor housing 4, front end housing 1, rear end cap 2, bonnet 5, oil cap 6, rotor 7, negative pressure chamber 8, front end housing 1, rear end cap 2 are installed in the two ends of motor housing 4, rotor 7 is installed in the motor housing, oil cap 6 is installed on the front end housing 1, negative pressure chamber 8 is installed on the oil cap 6, and bonnet 5 is installed on the rear end cap 2.

Common O RunddichtringO 3 all is housed on front end housing 1, the rear end cap 2, press fit over the inner place of the mouth of pipe of motor housing 4, reach sealing effectiveness by expanding naturally of O RunddichtringO 3, because being thin ripple type corrosion resistant plates, motor housing 4 is rolled into type by furling plate round machine, also has certain not slick and sly or out-of-flatness at weld, like this, O RunddichtringO 3 can't definitely reach sealing effectiveness.The place's perforate of motor housing mouth of pipe cylindrical in the screw that tapping is made in advance of bolt 9 screw-in front and rear covers again, is fixed on the motor housing front and rear cover, like this, in fact O RunddichtringO 3 does not reach the effect of mutual extrusion, thereby, reduced pressure expansion, leakproof is undesirable.Because water inlet, leaky in use often appear in above mechanical structure, the motor of existing submersible type aerator.In addition,, when water or sea-farming use, easily get rusty because front and rear cover all is the ironcasting that adopts, the one, pollute natural environment, the 2nd, outward appearance is not attractive in appearance.

The purpose of this utility model is exactly in order to overcome the deficiency of above-mentioned technology, and a kind of novel submersible type aerator motor with pull rod device is provided.

The novel submersible type aerator motor of band pull rod device, comprise motor housing 4, front end housing 1, rear end cap 2, bonnet 5, oil cap 6, rotor 7, negative pressure chamber 8, it is characterized in that also comprising pull bar 11, tie rod hole is all arranged on front end housing, rear end cap and the bonnet, pull bar passes bonnet, front end housing, rear end cap and is strained and fixed, when stationary state, the face that heals up of the plane of front end housing, rear end cap and motor housing in one plane.

Because this structure of the present utility model, pull bar passes bonnet, front end housing, rear end cap and is strained and fixed, and fastening force is strong, and when stationary state, the face that heals up of the plane of front end housing, rear end cap and motor housing in one plane.When oil cap is installed in the motor housing port, sealing ring and motor housing port plane contact on the oil cap, when bonnet is installed in the motor housing port, sealing ring and motor housing port plane contact on the bonnet, significant sealing affection.The utility model front end housing, rear end cap do not expose, thereby are difficult for getting rusty, and can not pollute natural environment, good looking appearance.

Fig. 1 is the structural representation of existing submersible type aerator motor;

Fig. 2 is a structural representation of the present utility model.

The 1st, front end housing, the 2nd, rear end cap, the 3rd, sealing ring, the 4th, motor housing, the 5th, bonnet, the 6th, oil cap, the 7th, rotor, the 8th, negative pressure chamber, the 9th, bolt, 10 mechanical shaft seals, the 11st, pull bar.

As shown in Figure 2, the novel submersible type aerator motor of band pull rod device, comprise motor housing 4, front end housing 1, rear end cap 2, bonnet 5, oil cap 6, rotor 7,8,4 pull bars 11 of negative pressure chamber, tie rod hole is all arranged on front end housing, rear end cap and the bonnet, 4 pull bars pass bonnet, front end housing, rear end cap and are strained and fixed, when stationary state, the face that heals up of the plane of front end housing, rear end cap and motor housing in one plane.

Front end housing 1, rear end cap 2 are installed in the two ends of motor housing 4, and rotor 7 is installed in the motor housing, and oil cap 6 is installed on the front end housing 1, and negative pressure chamber 8 is installed on the oil cap 6, and bonnet 5 is installed on the rear end cap 2, so front end housing, rear end cap do not expose.

Oil cap is taper, the oil cap vertex of a cone is placed static seal, the sealing of vertex of a cone internal mechanical, first, second seal groove is arranged in the oil cap, sealing ring is installed in the seal groove, the internal diameter of oil cap is slightly larger than the dynamo-electric shell mouth of pipe, makes first seal groove of oil cap aim at dynamo-electric display pipe mouth plane, and second seal groove is aimed at the oil pocket plane of front end housing.

When oil cap was installed in the motor housing port, oil cap and motor housing port plane contact under the fastening effect of pull bar and bolt, were close on the plane of front end housing and with the motor housing port sealing sealing ring of winning, thereby reach the optimum efficiency of leakproof; Second sealing ring in the oil cap chamber also is close to front end housing, prevents lubricated leaking outside in the chamber.

Bonnet is the garden cylindricality, and the bonnet internal diameter is greater than the dynamo-electric shell mouth of pipe, and place, bonnet endoporus plane is provided with seal groove, and sealing ring is installed in the seal groove.When bonnet was installed in the motor housing port by pull bar, bonnet and motor housing port plane contact were carried out protection against leakage by sealing ring, since the fastening effect of pull bar, significant sealing affection.
