Abstract

The utility model relates to the technical field of water pumps, in particular to a self-absorbing no-plugging sewage discharging pump of a novel fixing structure sealing device. The utility model is characterized in that the self-absorbing no-plugging sewage discharging pump of a novel fixing structure sealing device comprises an inlet connection tube, an inlet valve, a middle connection tube, a watering bolt, an outlet connection tube, a pump body, a gas-liquid separating tube, a rear cover, a bearing seat, an impeller, a machine seal, a pump shaft, a flat key, a coupler, a bearing, a bearing cover, an impeller pad sheet, an impeller fastening bolt and a water discharging cover. The machine seal is composed of a moving ring and a static ring to connect the impeller, and the static ring is connected with the rear ring. Thus, a problem that a middle sealing ring is easy to loosen to affect efficiency when the pump shaft and the impeller work is solved.

Description

A kind of self-priming no-blocking pollution discharging pump of novel stationary structure seal arrangement

Technical field

The utility model relates to the pump technology field, especially a kind of self-priming no-blocking pollution discharging pump of novel stationary structure seal arrangement.

Background technique

Tradition self-priming pump blowdown mechanical seal does not have stationary structure, and is loosening easily during work, causes gas leakage, and pollution discharge pump was lost efficacy, thereby influenced the working efficiency of pump.

Summary of the invention

A kind of self-priming no-blocking pollution discharging pump of novel stationary structure seal arrangement, it is characterized in that comprising (Fig. 1) entrance sleeve 1, inlet valve 2, middle adapter 3, add timber bolt 4, discharge connection 5, the pump housing 6, gas-liquid separation pipe 7, bonnet 8, bearing support 9, impeller 10, mechanical seal 11, pump shaft 12, flat key 13, coupling 14, bearing 15, bearing cap 16, impeller pad 17, impeller clamping bolt 18, discharge water and cover 19, described mechanical seal structure is divided into rotating ring (Fig. 2,3) and stationary ring (Fig. 4,5) two-part.Design has 2 fixing pins (Fig. 2) 21 on the rotating ring, is connected with impeller (Fig. 1) 10 fixed grooves; Design has 2 fixed grooves (Fig. 4) 41 on the stationary ring, is connected with bonnet (Fig. 1) 8 fixing pin fixed pins.Overcome the problem of loosening gas leakage like this, and then running and stationary ring is motionless of rotating ring guarantees the sealing proper functioning when impeller operation.

The utility model effect is: 1. when having overcome the work of pump shaft and impeller, the intermediate seal ring is loosening easily, and pump efficiency is low; 2. it is loosening easily to have overcome seal ring, causes the problem of leaking gas; 3.. simple and practical, easy for installation, reduce cost, improved working efficiency and provided cost savings.
