Slurry pump for building construction

Abstract

The invention introduces a slurry pump for building construction, which includes a pump body, the inner side of the pump body along the longitudinal direction and the outer side along the longitudinal direction are arc-shaped, and There are openings at the lower end, and an impeller is installed in the pump body. There is a protrusion in the middle of the impeller. A slurry delivery channel, the slurry delivery channel has openings at both ends of the impeller, and a transverse feed inlet is provided on the right side of the pump body, the feed inlet is directly opposite to the protrusion on the impeller, and the feed inlet The feed port communicates with the slurry channel on the impeller, and there is a connection hole on the left side of the pump body. The connection head on the left side of the impeller is snapped into the connection hole, and the transmission shaft passes through the connection hole from the left. After the hole, it is fixedly connected with the impeller. The invention improves the flow rate of the pump, reduces the vibration and noise when the equipment is in operation, reduces the friction and reduces the failure rate of the equipment at the same time.

Description

technical field [0001] The invention relates to a construction tool, in particular to a slurry pump used for construction, and belongs to the technical field of construction engineering. Background technique [0002] The power consumption of water pumps accounts for a large proportion of the country's total electricity. The energy saving of water pumps has an important impact on the national economy. Water pumps not only play an active role in energy saving, but also play an important role in the process of thermal power generation emission reduction. In addition to pumping water, the water pump can also pump gas, solid, and solid-liquid mixture, so the slurry pump came into being. [0003] Slurry pump refers to the pump that contains suspended solids in the conveying liquid (water). It is a kind of centrifugal pump in terms of working principle. Conceptually speaking, it refers to the centrifugal force (rotation of the pump impeller). A mechanical device that increases the...

Problems solved by technology

[0004] Aiming at the above-mentioned deficiencies in the prior art, the main purpose of the present invention is to solve the current problems of the slurry pump due to the aging of the structural design, resulting in insufficient pump flow and relatively high working noise, and to provide a method that can obtain a larger Slurry pumps for building construction with high pump flow rate, good sealing performance and low working noise
