The utility model discloses a high-speed pump exhaust apparatus can see clearly the exhaust condition of high-speed pump, just so can rationally arrange carminative time according to the production actual conditions. The shell of the high-speed pump is provided with a vent pipeline, and the vent pipeline is led to the reflux tank or the tank body at the inlet of the high-speed pump, so that the waste is reduced.
Description
Technical Field
The utility model relates to a chemical industry equipment field, specifically speaking, the utility model relates to a high-speed pump exhaust apparatus.
Background
High-speed pumps are often used in chemical enterprises, and are generally used in places with small flow and high lift. The most important link before the high-speed pump is started is air exhaust, and each air exhaust needs a great deal of time, otherwise, the high-speed pump cannot be normally started. The high-speed pump air exhaust method generally opens an exhaust valve between an inlet pipeline and an outlet pipeline for exhausting air, because the air exhaust condition is not clear, the pump is started by feeling each time the pump is started, the pump is started when the air exhaust is good, sometimes the pump has to be stopped for exhausting air again because the air exhaust is not thorough, so that a large amount of time is repeatedly wasted, sometimes the time is urgent, the high-speed pump cannot be normally started all the time, and great troubles are brought to production personnel.
Disclosure of Invention
The utility model aims to solve the technical problem that a high-speed pump exhaust apparatus is provided, the exhaust condition of high-speed pump can be seen clearly to the device, just can rationally arrange the exhaust time according to the production actual conditions.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: the utility model provides a high-speed pump exhaust apparatus, includes backward flow jar, high-speed pump, discharge valve and backflow pipeline, the backward flow jar passes through the pipeline and is connected with the high-speed pump, and the high-speed pump passes through the pipeline and is connected with discharge valve, and discharge valve passes through the pipeline and is connected with the backward flow jar, set up the sight glass on the pipeline of being connected between discharge valve and the high-speed pump.
Adopt the technical scheme of the utility model, can obtain following beneficial effect:
the utility model discloses a high-speed pump exhaust apparatus can see clearly the exhaust condition of high-speed pump, just so can rationally arrange carminative time according to the production actual conditions. The shell of the high-speed pump is provided with a vent pipeline, and the vent pipeline is led to the reflux tank or the tank body at the inlet of the high-speed pump, so that the waste is reduced.
Drawings
The contents of the description and the references in the drawings are briefly described as follows:
FIG. 1 is a schematic structural view of the apparatus;
the labels in the above figures are: 1. a reflux tank; 2. a high-speed pump; 3. a sight glass; 4. an exhaust valve; 5. a return line.
Detailed Description
The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings, in which the shapes, structures, mutual positions and connection relationships of the respective members, the functions of the respective portions, the operation principles, and the like of the respective members are described.
The housing of the high speed pump 2 typically has a vent line that discharges the gas to a flare or direct venting, which is also the vent line for the high speed pump 2. If the material is directly discharged to a flare emptying pipeline, great waste is caused. Therefore, we have modified this vent line by first adding a sight glass 3 to the return line 5 and then reintroducing the vent line to the return tank 1 or tank at the inlet of the high speed pump 2.
As shown in fig. 1, when exhausting, the operator opens the exhaust valve 4, and starts exhausting, and the operator can see the exhaust condition at any time through the sight glass 3. If the pump body is aerated, obvious bubbles can emerge from bottom to top in the sight glass 3, and discharged gas carries liquid to enter the reflux tank 1 at the inlet of the high-speed pump 2, so that the waste of materials is avoided. Once the air exhaust is finished, air bubbles are not generated in the sight glass 3, meanwhile, the sight glass 3 is filled with materials, the air exhaust can be considered to be complete, and the operator can close the air exhaust valve 4 to prepare for starting the high-speed pump 2. The method has three advantages that firstly, the condition of early exhaust is provided, once the high-speed pump is ready to be started, the operator can greatly advance the exhaust time, open the exhaust valve 4 to exhaust in half a day or even longer, the exhausted entrained liquid returns to the reflux tank 1 through the reflux pipeline 5, the liquid level of the reflux tank 1 cannot be influenced, and therefore, the exhaust is finished before the high-speed pump 2 is started, and the production efficiency is greatly improved; the exhaust condition can be observed at any time by an operator, the exhaust condition is clear at a glance, and the method of exhausting gas by feeling in the past is changed; and thirdly, production eyes are provided for operators, the previous pump is only considered to be incomplete in air exhaust once being started, the result is repeatedly exhausted until the last pump cannot be started normally, and the operators can accurately find reasons from other aspects if the reasons are not the air exhaust reasons.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements can be made without modification to the method and technical solution of the present invention, or the present invention can be directly applied to other occasions without modification, all within the scope of the present invention.
