Description

Technical Field

[0001] The utility model relates to the field of pump speed monitoring, in particular to a coupling collar for monitoring the speed of a pump. Background Art

[0002] The rated speed of a pump is calculated and set by designers at the beginning of its design. Therefore, when the pump is running, the speed input by the driver to the pump should match the pump. Otherwise, problems such as vibration, inability to operate, rotor loosening, and component damage may occur. In severe cases, it may even cause the pump set to jam and the equipment to be scrapped. Therefore, it is very necessary to monitor the water pump speed for the operation and maintenance of the pump. Summary of the Invention

[0003] The purpose of the utility model is to provide a coupling collar for monitoring the speed of a pump.

[0004] To achieve the above purpose, the technical solution of the utility model is: a coupling collar for monitoring the speed of a pump, including a set screw, a coupling collar, a pump coupling, a speed measurement probe, and a probe bracket. It is characterized in that: the coupling collar is sleeved on the outer circle of the small end of the pump coupling, and the end faces of the coupling collar and the small end of the pump coupling are flush. The coupling collar is circular, and a sunk groove is provided on the outer circle surface of the coupling collar. A threaded hole pointing to the axis line is provided at the bottom of the sunk groove, and the coupling collar is fixed to the pump coupling by the set screw in the threaded hole. The speed measurement probe is installed on the probe bracket, and the speed measurement probe points to the outer circle surface of the coupling collar.

[0005] When the utility model monitors the pump speed, it is not necessary to damage the pump coupling body. The structure is simple and easy to install, convenient for mass production, and reduces the manufacturing and operation and maintenance costs. Brief Description of the Drawings

[0011] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0012] In the figure, a coupling collar for monitoring the rotational speed of a pump includes a set screw, a coupling collar, a pump coupling, a speed measurement probe, and a probe bracket. It is characterized in that: the coupling collar is sleeved on the outer circle of the small end of the pump coupling, and the end faces of the coupling collar and the small end of the pump coupling are flush. The coupling collar is circular, and a counterbore is provided on the outer circle surface of the coupling collar. A threaded hole pointing to the axis line is provided on the bottom surface of the counterbore, and the coupling collar is fixed to the pump coupling by the set screw in the threaded hole. The speed measurement probe is installed on the probe bracket, and the speed measurement probe points to the outer circle surface of the coupling collar.

[0013] During implementation, as Figure 1 and Figure 2 shown, the speed measurement probe 4 points to the coupling collar 2. During the process of the coupling collar 2 rotating along the axis line together with the pump coupling 3, every time the counterbore 201 on the outer circle of the coupling collar 2 appears, the distance between the speed measurement probe 4 and the coupling collar 2 changes once, that is, the rotational speed of the pump coupling 3 is monitored by relying on the speed measurement probe 4.

[0014] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
