New detachable direct connection horizontal single-stage pump

Abstract

The invention relates to a new detachable direct connection horizontal single-stage pump. The single-stage pump consists of three parts, which are a pump, an elongated shaft motor and a pedestal, and is characterized in that the pump comprises a pump body, an impeller, a pump cover and a mechanical seal, wherein the part for mounting the elongated shaft motor of the pedestal is provided with a dovetail groove sliding guide rail; the pump body is fixedly arranged at one end of the pedestal by bolts; the bottom of the elongated shaft motor is provided with a dovetail groove; the dovetail groove at the bottom of the elongated shaft motor is formed in the dovetail groove sliding guide rail on the pedestal. The impeller, the pump cover, the mechanical seal and the elongated shaft motor are assembled into an integrated component. The single-stage pump has the advantages that the disassembly is flexible and convenient during maintenance or replacement of a spare part since a back opening door type structure is adopted, the maintenance or replacement of the spare part is also extremely easy and no special lifting appliance or personnel are required even if a high-power motor pump unit is arranged so that the maintenance time and cost are saved, the motor is in direct connection with the pump so that the middle structure is simplified and the stability of operation is enhanced, the pump has a simple structure and is easy to implement, the defects of the conventional direct connection single-stage pump are overcome and the requirements for field use of clients can be fully met.

Description

technical field [0001] The invention relates to a new type of detachable direct-connected horizontal single-stage pump. Background technique [0002] Conventional direct-coupled horizontal single-stage pump, integrated with pump, consists of three parts: pump, extended shaft motor and base. The pump structure includes pump body, impeller, pump cover, mechanical seal and other parts. The pump is a single-stage single-suction horizontal centrifugal pump. The pump body and the pump cover are divided from the back of the impeller, which is the rear door structure. The pump and motor are coaxial, directly assembled, and have a common base. (if attached figure 1 shown), and the extended shaft structure using this whole shaft structure will have the following disadvantages: [0003] This series of direct-coupled horizontal single-stage pumps has a rear door-opening structure. When repairing or replacing accessories, the pump body can only be disassembled for inspection or repla...

AI Technical Summary

Problems solved by technology

[0003] This series of direct-coupled horizontal single-stage pumps has a rear door-opening structure. When repairing or replacing accessories, the pump body can only be disassembled for inspection or replacement of accessories by disassembling the motor and removing the motor. If it is a larger pump set, Equipped with a high-power motor, it is quite difficult to disassemble and move, requiring professional lifting equipment and personnel, thus increasing maintenance time and cost
