Abstract

The utility model relates to an attachment for a submerged pump, solving the problem that after the connection in series, general submerged pumps can extract the low water level groundwater for irrigation. The connector of two lifting submerged pumps is composed of an upper part of the connector, a lower part of the connector, and a connecting piece and is characterized in that the former part is a pipe fitting with one end provided with a joint and the other end provided with a flange, and the latter part is a water pump chamber with one end provided with a flange and the other end provided with a joint. A grade A submerged pump is arranged under the water pipe of a pumping well, a grade B submerged pump is arranged in the water pump chamber, and the upper part and the lower part of the connector are combined into integration by flanges, easily meeting the actual demand of the extraction of the low water level groundwater for irrigation. The construction is easy, and the cost of the well construction is reduced.

Description

Connector for two-stage water-raising submersible pump

The utility model relates to the submersible pump annex.

To surpassing under 70 meters the situation, if adopt the submersible pump one-level to pump up water, its lift has not reached 70 meters height in some regional groundwater recession, if adopt more high-lift submersible pump, then owing to the restriction of well casing diameter, the water pump volume is big, be the diameter that its diameter surpasses well casing, can't install.As enlarge the well casing diameter and also be subjected to the restrictions such as cost, technical specifications of digging a well, the motor-pumped well construction is difficulty relatively also; If take the submersible pump series connection relay water lift of two general lifts, still be not a reasonable technological scheme, but must solve the connector issue of its series connection.

The purpose of this utility model just is at the above-mentioned situation and the problem that exist, designs for the pump up water submersible pump connector of usefulness of two-stage.

The purpose of this utility model is achieved in that the two-stage submersible pump connector that pumps up water, and is made up of connector top and connector lower tube and coupling, it is characterized in that connecting product top and is a upper end and take the pipe fitting that water swivel, lower end are established the upper flange dish out of; The discrepancy water pipe adapter that the connector bottom is a upper end band lower flange dish, establish the lower end joins with first class submersible pump outlet pipe in order to the tubular container of second class submersible pump to be installed, it is pump chamber, and on the upper flange dish, be provided with the water pump attachment hole that the second class submersible pump is installed, synthetic as a whole by being connected of upper flange dish and lower flange dish connector top and connector lower junction.

Though above-mentioned design proposal structure is simple, solved the series connection problem of two submersible pumps dexterously, successfully satisfied the actual demand that low water level underground water is irrigated by lifting water to a higher level with a water pump, etc., to build easily, the shaft building cost reduces, the very big economic value of tool.

The utility model is described in further detail below by drawings and Examples:

Fig. 1 is the utility model decomposition texture schematic representation.

Fig. 2 installs in conjunction with schematic representation for the utility model.

Mark among the figure: 1. titting water outlet, 2. water pump attachment hole, 3. pump chamber, the water pipe adapter of 4. coming in and going out, 5. first class submersible pump outlet pipe, 6. second class submersible pump, 7. water outlet, 8. motor-pumped well bassoon, 9. upper flange dish, 10. water inlet pipe, 11. lower flange dishes, 12. motor-pumped well tubules.

As shown in the figure: the two-stage submersible pump connector that pumps up water, form by connector top and connector bottom and coupling, it is characterized in that connecting product top and be a upper end and take the pipe fitting that upper flange dish 9 is established in water pipe adapter 1, lower end out of; The discrepancy water pipe adapter 4 that the connector bottom is a upper end band lower flange dish 11, establish the lower end joins with first class submersible pump outlet pipe 5 in order to the tubular container of second class submersible pump to be installed, it is pump chamber 3, and on upper flange dish 9, be provided with the water pump attachment hole 2 that the second class submersible pump is installed, synthetic as a whole by being connected of upper flange dish 9 and lower flange dish 11 connector top and connector lower junction.

Claims
