Abstract
The utility model discloses an equipment cooling water return monitoring device. The device comprises a connecting plate and a rotating shaft which is fixed on the middle part of the connecting plate, wherein one end of the connecting plate is connected with a return funnel, and the other end of the connecting plate is provided with a bolt; the bolt is provided with a balance weight; and a limit switch is arranged below the connecting plate and connected with a control system. By using the technical scheme, the device has a simple structure, can adjust balance for equipment needing different cooling water quantities by changing the balance weight and meets the actual requirements of the process.
Description
Technical field
The utility model relates to a kind of monitoring device, specifically relates to a kind of monitoring device of monitoring equipment chilled water backwater state.
Background technology
The cooling of equipment is directly connected to the safe operation of equipment itself, also has influence on safe, the stable operation of whole production system simultaneously.The chilled water detection method of using mainly contains following several at present.
1, thermometer: by measuring the cooling effect of return water temperature judgment device, if use liquid-filled thermometer, temperature signal can not long-distance transmissions, the automatic monitoring of inconvenient system.Use thermopair or thermal resistance, can realize the long-distance transmissions of temperature, but the time certain hysteresis is arranged, chilled water may work the mischief even the equipment major accident occurs unusually equipment.
2, flowmeter: the circling water flow rate meter can accurately detect circling water flow rate, detect promptly and accurately, but the disposable input of equipment is too big, and expense is too high, troublesome maintenance.
3, range estimation: by state to the observation judgment device chilled water of the chilled water water yield.This method requires the employee to have the sense of responsibility of height, and expends a large amount of time, is easy to occur because the problem of employee's sense of responsibility causes component cooling water unusual.
Summary of the invention
The purpose of this utility model provides the component cooling water backwater pick-up unit of a kind of economic and reliable, easy maintenance.
For achieving the above object, the utility model is by the following technical solutions:
The rotating shaft that the utility model comprises web joint and is fixed on the web joint middle part, at the end connection backwater funnel of described web joint, the other end erection bolt at web joint is provided with counterweight on the bolt; And limit switch is set below described web joint, and limit switch is connected with control system.
Described counterweight is made up of the corrosion resistant plate of at least one homalographic.
Adopt the utility model of technique scheme, simple in structure, can take to change counterweight for the equipment of the different cooling water inflows of needs and how much carry out the balance adjustment, satisfy the actual requirement of technology.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is a vertical view of the present utility model.
Embodiment
As shown in Figure 1 and Figure 2, the rotating shaft 3 that the utility model comprises web joint 2 and is fixed on the web joint middle part is installed axle sleeve and can be rotated freely along surface level afterwards.
End at above-mentioned web joint 2 connects backwater funnel 1, and backwater funnel perforate one fixes on the below of funnel.The other end at web joint 2 punches with erection bolt 5, and counterweight 4 and nut 6 are set on the bolt 5.Above-mentioned counterweight 4 is made up of the corrosion resistant plate of at least one homalographic, and perforate in the middle of the counterweight 4 is so that install.Need to prove that the quantity of corrosion resistant plate can be set according to actual needs in the counterweight 4, can take to change counterweight for the equipment of the different cooling water inflows of needs and how much carry out the balance adjustment, satisfy the actual requirement of technology.
And limit switch 7 is set below described web joint 2, and limit switch 7 is connected with control system.Web joint can contact limit switch when counterweight 4 descends, and the switching value signal is sent to control system, detects the chilled water state.
Principle of work of the present utility model is:
Claims (2)
1. component cooling water backwater monitoring device, it is characterized in that: the rotating shaft (3) that it comprises web joint (2) and is fixed on the web joint middle part, end at described web joint (2) connects backwater funnel (1), other end erection bolt (5) at web joint (2) is provided with counterweight (4) on the bolt (5); And in the below of described web joint (2) limit switch (7) is set, limit switch (7) is connected with control system.
