Description
Technical field
The utility model relates to the pump technology field, especially a kind of new type mining flame proof sand discharging pump.
Background technique
The utility model is a kind of being used for to contain silt in the shallow water conveying water under the coal mine, and is using the on-the-spot mode of connection that need change motor windings to adapt to the built-in type mining flame-proof type submersible sand discharging electric pump of supply voltage conversion.At present, built-in type mining flame-proof type submersible sand discharging electric pump is in order to adapt to colliery drainage underground demand, its water outlet, the position majority of outlet above the unit be the unit overcoat above, as Fig. 1 is the accompanying drawing of the specification of 200420015632.7 patents, its major character is outlet and water outlet on the same lid and the shaft axis of outlet not on the shaft axis at unit, it is bad that its major defect is that outlet shaft axis and the shaft axis of unit overcoat loam cake of the motor loam cake mode of connection do not overlap manufacturability, and the terminal box that can change motor windings is not set, so can not adapt to the demand that supply voltage is 380V and 660V or 660V and 1140V in the mode of connection of the on-the-spot conversion motor windings of user.As patent 200620084577.6, its major defect is to be difficult to the terminal box that can change the motor windings mode of connection is set, and just can not use if user's supply voltage changes.As patent 200920018000.9, though this patent is provided with the terminal box that changes the motor windings mode of connection on top, but extremely bother at user's execute-in-place, and above three patents exist jointly thrust that pressure medium makes progress at the outlet pipe place very big (cause that the area of contact that medium makes progress is big) just overcoat might be drawn back like this, do not draw back and the thicker and ribbing of outer Analysis of Nested Design will be handled if do not make, the manufacture cost and the cost of material of pump are increased, do not meet energy-conservation needs.Also exist the terminal box simultaneously in high-pressure medium, increased medium and entered and make electrical machine insulation reduce the possibility that burns out motor in the motor.
The model utility content
In order to overcome the deficiency that existing built-in submerged motor pump exists, the utility model provides a kind of new type mining flame proof sand discharging pump, the new structure mode that described a kind of new type mining flame proof sand discharging pump is water outlet and outlet, described a kind of new type mining flame proof sand discharging pump goes out line position above pump, water outlet is in the middle and upper part of pump, and a terminal box that can make things convenient for the conversion motor windings mode of connection arranged on the top of pump, not only make, install, keep in repair very convenient, and can adapt to the demand that supply voltage is 380V and 660V or 660V and 1140V in the mode of connection of user scene conversion motor windings very easily, be provided with the needs that overcoat not only can play draining in shallow water simultaneously, also the thrust that makes progress because of medium little (area of contact that medium makes progress is few) makes this product safe and reliable under coal mine, manufacture cost, cost of material is relative also lower, and energy-saving effect is remarkable.
The technological scheme that its technical problem that solves the utility model adopts is: described a kind of new type mining flame proof sand discharging pump, it is characterized in that being provided with a terminal box on the unit top of built-in type mining flame-proof type submersible sand discharging electric pump, 6 wiring terminals are arranged in the described terminal box, the mode of connection that is used for the conversion motor windings, the bottom of terminal box is provided with electric machine casing and cooperates seam, the bottom of described terminal box cooperates seam coaxial with the unit shaft axis with electric machine casing, the top of terminal box is stamped with terminal box and is cooperated seam, described terminal box top cooperates seam coaxial with the unit shaft axis with connector cover, and the elastic cable paper of unit is drawn from the top of connector cover.Described a kind of new type mining flame proof sand discharging pump, its outlet pipe setting on the coat, be set in the unit middle and upper part of built-in type mining flame-proof type submersible sand discharging electric pump outward, and outlet pipe does not exceed the overall dimensions of unit base, overcoat is provided with volute, electric machine casing, terminal box Spielpassung and cooperates seam, and be provided with the O RunddichtringO and prevent the medium leakage, described overcoat shaft axis is coaxial with the unit shaft axis.When the user needs the mode of connection of conversion motor windings, as long as it is just passable to open the connector cover conversion mode of connection on request.
The beneficial effects of the utility model are not only adapt to the conversion of user's supply voltage, and terminal box not to contact high-pressure medium, the probability of motor unit inner inlet is little, and the thrust that makes progress of medium little and use safe and reliable, low cost of manufacture, save material, energy-saving effect is remarkable.
