Embodiment Construction

[0021] In order to make the technical means, creative features and objectives of the present invention easy to understand, the present invention will be further elaborated below in conjunction with specific examples

[0022] like figure 1 As shown, a pulsation-free rotor pump (Q type) includes a rotating shaft and a bearing connected to the rotating shaft. The rotating shaft is arranged in parallel with the bearing. At least one helical rotor is arranged on the rotating shaft, and the helical rotor is uniformly Distributed on the rotating shaft 2, the rotating shaft 2 is fixed on a rotor pump housing 1. And the other end is fixed as a whole through a rotor cover 4 .

[0023] The helical rotor includes a rotor body 32 and slanted wings 31 , any two adjacent slanted wings are helically connected at any angle. Two adjacent oblique wings are in the shape of an "S". The upper and lower sides of the spiral body are provided with the inclined wings, and the upper and lower incline...

Abstract

The invention discloses a pulseless rotor pump (Q type). The pulseless rotor pump comprises a rotating shaft and a bearing connected with the rotating shaft, and is characterized in that the rotating shaft and the bearing are arranged in parallel, at least one spiral rotor is arranged on the rotating shaft, and the spiral rotors are uniformly distributed on the rotating shaft. The pulseless rotor pump disclosed by the invention can be quickly repaired on the site, and wearing parts at the part of a pump chamber, including the rotors, a wear-resistant plate and machinery can be sealed by axially moving an end cover easily, so as to realize replacement on the site under the situation of not detaching pump inlet and outlet pipe fittings and a pump body.

Description

technical field [0001] This invention relates to rotary lobe pumps, more specifically to a pulsation-free rotary lobe pump (type Q). Background technique [0002] Usually positive displacement pumps, including rotor pumps, need to dismantle the pump inlet and outlet connecting pipelines and remove the pump as a whole during maintenance. This increases the work intensity on the one hand, and on the other hand increases user downtime losses and costs. [0003] On-site rapid maintenance type, detachable rotor pump (Q type), replacement of pumping chamber spare parts including rotor, wear-resistant plate, mechanical seal, no need to disassemble the pump inlet and outlet connecting pipelines, one person on site, the replacement can be completed within 2 hours , the rotor pump resumes operation. Greatly reduce user downtime losses. At the same time, the non-helical rotor is used, which limits the maximum output flow of the pump. [0004] The pump casing can be moved radially a...
