CN2399540Y - High pressure spiral centrifugal pump vane - Google Patents

Abstract

The utility model discloses an impeller for high pressure spiral centrifugal pumps. Side walls of the impeller are fixedly connected in a symmetry plane spiral shape by two pressurizing isolating sheets. The utility model overcomes a traditional method that pumps in the class of high pressure blades need a plurality of sets of impellers to reach requested pressure, and thus, the utility model is a novel blade type impeller in the class of pumps and can complete the working pressure of a plurality of sets of general impellers by a set of impellers for high pressure spiral centrifugal pumps.

Description

The high-pressure spiral centrifugal pump impeller

The utility model belongs to a kind of main working parts of vane type oil pump---impeller.

Before the utility model was made, designs fix was in ward off in substantially radially by impeller side for the impeller blade of pump class of the same type, and its working pressure depends on the centrifugal force that the impeller rotation is produced fully.If when needing elevated pressures then must adopt the multi-stage impeller work in combination just can finish.

This practical task provides a kind of high-pressure spiral centrifugal pump impeller, high-pressure spiral centrifugal pump and common blade formula pump class by this high-pressure spiral centrifugal pump impeller assembly are made under the conditions such as volume, weight, power, cost equal, compare have simple in structure, sealing is reliable, working flow is big and stablize, raise (suction) journey advantages of higher, particularly work and raise (suction) journey, can reach and raise more than 2 times of (suction) journey under the equal operating conditions of common blade formula pump class.

This practical task is finished by following technical proposals: a kind of high-pressure spiral centrifugal pump impeller, respectively be provided with impeller negative pressure suction nozzle and connecting shaft end body on the sidewall of both sides, and it is affixed and be integral to be the snail type by 2 supercharging partitions between the sidewall of both sides.

By embodiment, the utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model embodiment plan view

Fig. 2 is the I-II sectional view of Fig. 1

Fig. 3 is the II-II sectional view of Fig. 1

The central upper portion of seeing Fig. 1, Fig. 2, Fig. 3, round impeller sidewall 2 is with concentric, requirement is provided with round impeller negative pressure suction nozzle 1, the bottom of round impeller sidewall 3 requires to be provided with round connecting shaft end body 5 with concentric, and it is affixed and be integral that the top of the bottom of round impeller sidewall 2 and round impeller sidewall 3 is the symmetry plane screw type by two supercharging partitions 4.

Tell use working principle of the present utility model below:

The high-pressure spiral centrifugal pump impeller is equipped with other part of pump class, form high-pressure service pump: during work by the pump shaft transmission, direction high speed rotating and produce two kinds of power on request, be centrifugal force and by the outside spiral thrust effect of supercharging partition 4, with in the impeller negative pressure suction nozzle and the liquid in the impeller liquid chunnel 6 constantly inhale and press to release the impeller periphery and form pressure difference, reach raising more than 2 times (suction) journey when working under the equal operating conditions of common blade pump work.

Claims (1)

1. A kind of high-pressure spiral centrifugal pump impeller is characterized in that: respectively be provided with impeller negative pressure suction nozzle and connecting shaft end body on the sidewall of both sides, it is affixed and be integral to be the snail type by 2 supercharging partitions between the sidewall of both sides.
