Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of twin-screw pumps, and in particular relates to a high-temperature and high-pressure twin-screw pump. Background Art
[0002] A twin-screw pump consists of two intermeshing screws and a pump body. Its main components include pump head, twin screws, bearings, seals, inlet and outlet flanges, etc.
[0003] When a twin-screw pump is transporting high-temperature and high-pressure media, it is necessary to ensure its own sealing. However, the existing twin-screw pumps do not have a device to detect leakage. When a twin-screw pump has a slight leak, the high temperature and high pressure will cause the leakage point to expand, thereby causing the twin-screw pump to be damaged more severely and increasing the cost of subsequent maintenance of the twin-screw pump. At the same time, the leaked medium will pollute the environment and is not conducive to subsequent cleaning. Utility Model Content
[0004] The purpose of the utility model is to provide a high-temperature and high-pressure twin-screw pump to solve the problems raised in the above-mentioned background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-temperature and high-pressure twin-screw pump, comprising: a twin-screw pump body, a collecting bucket and a detection mechanism are sequentially installed along the longitudinal direction below the twin-screw pump body, the detection mechanism comprises a collecting bucket and a weighing mechanism arranged in the collecting bucket, the collecting bucket is detachably installed at the bottom of the collecting bucket, and the weighing mechanism is used to weigh and detect the collected medium.
[0006] Preferably, the weighing mechanism comprises a collecting cup and a pressure sensor with signal transmission, and the collecting cup is arranged on top of the pressure sensor.
[0007] Preferably, the bottom of the collecting hopper is connected with an interface, and the top end of the collecting barrel is screwed on the interface.
[0008] Preferably, a filter screen for filtering is provided on the inner side of the top of the collecting bucket, and a handle for holding is provided on the top of the filter screen.
[0009] Preferably, a support seat for support is also provided at the bottom of the twin-screw pump body, and the support seat is a U-shaped structure. The inner walls on both sides of the U-shaped structure of the support seat are horizontally provided with slide grooves, and the outer walls on both sides of the collecting bucket are symmetrically provided with sliders that can be detachably installed in the slide grooves on both sides.
[0010] Preferably, a mounting hole is opened inwardly on the outer side of the slider, and a limit pin and a spring are installed in the mounting hole in sequence from the outside to the inside. A limit hole coaxial with the limit pin is opened on the inner wall of the slide groove, and one end of the limit pin can be movably inserted in the limit hole.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] (1) The utility model adds a collecting bucket and a detection mechanism that cooperate with the twin-screw pump body. The leaked medium is guided to the weighing mechanism in the detection mechanism through the collecting bucket. When the weighing mechanism detects that the weighing medium reaches a predetermined threshold, the weighing mechanism sends a leakage signal to the outside, so that maintenance personnel can be informed of the equipment leakage as soon as possible.
[0013] (2) The utility model adds a collecting cup and a pressure sensor that cooperate with each other, and the leaked medium acts on the pressure sensor through the collecting cup, so that the medium can be weighed easily.
[0014] (3) The utility model adds a filter screen to prevent substances other than the medium from entering the collection bucket, thereby improving the accuracy of equipment detection. BRIEF DESCRIPTION OF THE DRAWINGS

When the twin-screw pump body 1 leaks, the leaked medium is collected into the collecting bucket 5 by the collecting bucket 3 under gravity. At this time, the medium falls onto the pressure sensor 7 through the collecting cup 6. When the pressure detected by the pressure sensor 7 exceeds the threshold, the pressure sensor 7 sends a signal to the external mobile end through its own signal transmission device, and the maintenance personnel can promptly repair the twin-screw pump body 1.
