FIG. 2 is a schematic structural view of a bushing;

FIG. 3 is a schematic structural view of an outer wire;

fig. 4 is a cross-sectional view of the cannula.

The device comprises a sleeve 1, an outer thread 2, a glass tube 3, a gasket 4, a water pump connecting flange 5, a vacuum tube connecting flange 6, an observation hole 7, an outer threaded tube 8 and a flange 9.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments, and it is to be understood that the described embodiments are merely illustrative of some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The first embodiment is as follows:

referring to fig. 1 to 4, the full water detection device for the non-self-priming pump comprises a sleeve 1, an outer wire 2 and a glass tube 3, wherein a stepped hole is formed in the center of the sleeve, the stepped hole is composed of a large hole and a small hole, the glass tube is arranged in the large hole, a gasket 4 is arranged at each of two ends of the glass tube, four observation holes 7 are formed in the wall of the sleeve and correspond to the glass tube, a water pump connecting flange 5 is arranged at the opening of the small hole, one end of the outer wire is in threaded connection with the opening of the large hole, and a vacuum tube connecting flange 6 is arranged at the other end of the outer wire.

Referring to fig. 1 and 3, in the present embodiment, the sleeve 1 is integrally cast and formed of copper, one end of the external thread 2 is provided with an external threaded pipe 8, an opening of the large hole is provided with internal threads, and the external threaded pipe is in threaded connection with the opening of the large hole.

Referring to fig. 3, in the present embodiment, the tail of the external thread is provided with a rib 9. When outer silk and sleeve pipe threaded connection, the flange plays limiting displacement, prevents that outer silk screw in is excessive, leads to glass pipe and packing ring to damage.

In this embodiment, the outer thread of the outer thread has an inner diameter equal to the inner diameter of the glass tube and the inner diameter of the small hole. The gasket is an asbestos gasket. The observation hole is a long hole arranged along the length of the glass tube. The observation hole and the glass tube wall form an observation window.

The full water detection device is connected with an air outlet pipeline on the top of a non-self-priming pump through a water pump connecting flange, and a vacuum pipe connecting flange is connected with a vacuum pipeline of a vacuum pump system. The vacuum pump system pumps air out of the non-self-priming pump casing to fill the pump body with water. And when the observation window observes that water flows through the observation window instead of the gas-water mixed solution, the water pump shell is judged to be filled with water and can be started. The air-water mixed liquid means that when air is sucked out under the condition that part of air in the pump shell is part of water, the water and the air are simultaneously pumped out, and the water and the air are in the form of air-water mixed liquid, namely the water is in the form of a large amount of bubbles. This full water detection device can be accurate, timely judgement water pump whether full water, avoids the water waste to when detecting instrument takes place the problem and need overhaul in vacuum pump system, also do not hinder the water pump normal operating.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
