Single-suction horizontal type oil pump

Abstract

The invention discloses a single-suction horizontal type oil pump comprising a pump body, an impeller rotationally arranged in the pump body, a pump shaft driving the impeller to rotate, a motor driving the pump shaft to rotate, a middle support fixedly connected with the pump body, and a fixing base used for fixing the pump body and the middle support. The side edge of the pump body is provided with an oil inlet communicating with the pump body. The top end of the pump body is provided with an oil discharge outlet communicating with the pump body. An abrasion-resistant rubber sleeve wrappingthe pump shaft is arranged in the middle support. A cooling water chamber surrounding the pump shaft is further arranged in the middle support. The surface of the bottom end of the middle support is provided with a water inlet communicating with the cooling water chamber. The surface of the top end of the middle support is further provided with a water discharge outlet communicating with the cooling water chamber. The pump body is fixedly connected with the fixing base through a first damping rubber pad. The middle support is fixedly connected with the fixing base through a second damping rubber pad. The motor is fixedly connected with the fixing base through a third damping rubber pad.

Description

technical field [0001] The invention relates to the mechanical field, more specifically, to a single-suction horizontal oil pump. Background technique [0002] In the field of petrochemical industry, when using an oil pump, the pump shaft is prone to heat after long-term use, which will affect the working efficiency of the oil pump and may also cause safety accidents. Simultaneously, during the working process of the oil pump, the vibration is severe, and the vibration is easily transmitted to the fixed base, causing the fixed base to become loose, resulting in a safety accident. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a single-suction horizontal oil pump for the above-mentioned defects of the prior art. [0004] The technical solution adopted by the present invention to solve the technical problem is to construct a single-suction horizontal oil pump, which includes a pump body, an impeller rotatably arr...
