Abstract

The invention relates to a mobile lifting drainage device, which comprises a vehicle body and centrifugal pumps, wherein each centrifugal pump is arranged on the tail part of the vehicle body and is provided with a lifting device; a self-priming pump pre-device is connected with the outlet of at least one centrifugal pump; and a solenoid valve is respectively arranged between pipelines for connecting the self-priming pump pre-device and the outlet of each centrifugal pump. According to the mobile lifting drainage device, one self-priming pump pre-device of a turbine can drain when a plurality of self-priming pumps are started, installation space is saved, the mobile lifting drainage device is more suitable for vehicle-mounted requirements to realize the purpose that the pumps and a vehicle can be cooperated optimally, cost is lowered, efficiency is improved, and the mobile lifting drainage device is suitable for popularizing and applying.

Description

technical field [0001] The invention relates to a drainage device, in particular to a mobile lifting drainage device, which is mainly suitable for flood control and fire protection fields such as municipal rainwater, waste water, accumulated water and fire-fighting water absorption. Background technique [0002] The pumps on the existing pump trucks mainly include mixed-flow pumps, centrifugal pumps with additional vacuum pumps, and submersible sewage pumps. The height of the body is 1.5m, the height of the pump center is 0.5m, the total is 2m, then the actual suction of the drainage pump will be reduced by 2m, resulting in a suction depth of only 3-4m. Moreover, the vehicle-mounted pump with the above structure has low head, small flow rate and low efficiency. Contents of the invention [0003] Aiming at the problems existing in the above-mentioned prior art, the present invention improves the structure of the turbo self-priming pump and the pump truck, and provides a mo...
