Abstract
The utility model relates to a chemical underwater shielded electrical pump, which relates to a pump, particularly the pump for conveying liquids with strong causticity. According to the design proposal of the utility model, a rotary shaft of a motor is connected with an impeller in a pump body and an outlet of the pump body is connected with an outlet pipe. The utility model is characterized in that corrosion resistant shielding sleeves are respectively arranged on the surfaces of a motor rotor and a motor stator, a liquid guide pipe is arranged on the outlet pipe and one end of the liquid guide pipe is connected with the motor. A passage is arranged between the shielding sleeves of the motor rotor and the shielding sleeves of the motor stator, an inlet and an outlet which are communicated with the passage are arranged on a casing of the motor and the liquid guide pipe is connected with the inlet of the passage. When the pump works, the pump body and the motor can be sunk into corrosive liquids, thus thoroughly eliminating problems of leakage, etc., simplifying the structure of the utility model and improving work efficiency.
Description
Technical field
The utility model relates to a kind of pump, specifically a kind of pump that is used for transporting strongly corrosion liquid.
Background technique
When chemical industry is transported the stronger acidic materials of corrosivity, usually utilize a kind of water pump that is referred to as major axis chemical industry Under Water Pumps, during work, motor is positioned at the top of corrosive liquids, directly do not contact with liquid, the long rotating shaft of motor utilization extends the pump housing that is positioned at liquid, is connected with impeller in the pump housing.The defective of this pump is that structure is big and complicated, and working efficiency is low, is unfavorable for maintenance.
Summary of the invention
The purpose of this utility model is to design shielded electric-pump under a kind of chemical industry liquid, and this pump is in when work, and the pump housing and motor all can sink in the corrosive liquids, thereby has thoroughly stopped problem such as leakage, and makes structure obtain simplification, and working efficiency is improved.
According to design proposal provided by the utility model, impeller in shaft of motor and the pump housing is connected, outlet at the pump housing connects outer pipe, it is characterized in that: corrosion resistant housing is set respectively on the surface of motor rotor and the surface of motor stator, liquid guiding tube is set on outer pipe, the other end of this liquid guiding tube is connected with motor, between the housing of motor rotor and the housing of motor stator passage is arranged, the import and export of setting and this channel connection on the housing of motor, liquid guiding tube is connected with the import of this passage.
Axle sleeve is set on shaft of motor, corrosion resisting bearing is installed, the bearing support that is used to locate corrosion resisting bearing is installed in the end of motor field frame at motor field frame and shaft room.The installation flexible joint reaches oneself and washes filter on liquid guiding tube, and liquid guiding tube is washed filter with oneself and is connected.At the end of liquid guiding tube installation outlet flange, the protective tube that is used to protect cable is installed on motor, in the end of protective tube explosion-proof outlet box is set.
The utility model has the advantages that because the motor and the pump housing all utilize resistant material to make, and the housing of shielding and corrosion-resistant effect has been set respectively on the surface of motor rotor and motor stator, therefore, in use, the pump housing and motor all can be sunk in the corrosive liquids and work, avoid original major axis, make structure obtain simplifying, improve working efficiency simultaneously, made things convenient for maintenance.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
Embodiment
As shown in the figure: the impeller 10 in shaft of motor and the pump housing 9 is connected, outlet at the pump housing 9 connects outer pipe 7, on the surface of motor rotor 16 and the surface of motor stator 17 corrosion resistant housing is set respectively, liquid guiding tube 6 is set on outer pipe 7, the other end of this liquid guiding tube 6 is connected with motor, between the housing of the housing of motor rotor 16 and motor stator 17 passage is arranged, the import and export of setting and this channel connection on the housing of motor, liquid guiding tube 6 is connected with the import of this passage.During work, impeller 10 in the motor drives pump housing 9 rotates, liquid is sent in the outer pipe 7, by outer pipe 7 liquid is delivered to the destination, wherein have in the passage of 17 of small amount of liquid process liquid guiding tube 6 anti-inflow motor rotors 16 and motor stators, because the surface at motor rotor 16 and motor stator 17 is provided with housing respectively, therefore the corrosive liquids of being introduced by liquid guiding tube 6 can not impact motor rotor 16 and motor stator 17.
At the end of liquid guiding tube 6 installation outlet flange 2, the protective tube 11 that is used to protect cable 12 is installed on motor, in the end of protective tube 11 explosion-proof outlet box 3 is set, with the blast problem of avoiding occurring.
