The technical scheme of the utility model is that: an acid and alkali resistant delivery pump with good safety comprises a pump body, wherein a transmission shaft arranged outwards is arranged in the pump body, an impeller is arranged in the pump body through the transmission shaft, the part of the transmission shaft extending out of the pump body is in power connection with a motor, the motor is fixed on the outer side of the pump body through a motor frame, and two semicircular protective covers are arranged on the outer side of the pump body; the protective cover is cross-sectionally personally submitted "C" type, the protective cover front end passes through fastening screw to be fixed in the pump body side, the mounting groove of placing the motor is left to the protective cover rear side, the mounting groove between place the casing of motor.
Furthermore, a shock pad is arranged between the mounting groove and the motor.
Further, the pump body and the transmission shaft between be equipped with the first sealing washer that closely sets up, first sealing washer make for acid and alkali-resistance material.
Further, the safety cover and the pump body between be equipped with the second sealing washer, the second sealing washer be two semi-circular sealing washers, the second sealing washer is arranged in between the safety cover and the pump body, the second sealing washer is made for acid and alkali-resistance material.
Further, the motor frame include two semi-circular solid fixed rings of parcel in the motor outside, solid fixed ring between put through the welded and fix together, be equipped with the blotter between solid fixed ring and the motor.
Furthermore, a containing groove with the depth of 3-5 cm is arranged at the bottom of the protective cover.
Advantageous effects
The utility model discloses an acid and alkali-resistance delivery pump that security is good is equipped with acid and alkali-resistance material between the pump body and the transmission shaft and makes first sealing washer, and the leakage of the inside liquid of the at utmost reduction pump body, liquid after the leakage is detained in the holding groove of guard shield bottom, can not spill the work place, does not influence operator's health.
