Brake, also known as electric motor brake, is a braking device attached to an electric motor. Its core function is to use a braking device to prevent further rotation of the motor when it stops working, in order to achieve rapid stopping or accurate positioning.

The working principle of motor brake can be divided into two types according to different designs: electromagnetic brake and spring brake. Electromagnetic brake operates based on electromagnetic principles. When the motor stops working, the current passes through the electromagnetic coil to generate a magnetic field, which attracts the brake disc or brake pad, thereby generating friction and causing the motor to quickly stop rotating. The spring brake uses the elastic force of the spring to push the braking device. When the motor stops, the spring releases its elastic force, pushing the brake pad to tightly contact the brake disc on the motor shaft, thereby achieving braking.

For example, in some automated equipment that requires precise position control, the motor brake plays a key role. When industrial robots perform precise grasping or placement tasks, the motor brake can ensure that the robot can stop immediately after reaching the position without any positional deviation. In addition, in vertical transportation equipment such as elevators, the motor brake also plays an important role in ensuring safety. When the equipment malfunctions or is abnormal, the motor brake can quickly brake to prevent further movement of the equipment, thereby protecting the safety of passengers and equipment.

In general, the motor brake is a safety device in the motor system, which uses electromagnetic or spring force to quickly brake when the motor stops working, ensuring the accuracy and safety of the equipment.

The principle of water flow switch is to measure the water flow rate. The accurate flow rate can be obtained by measuring the pressure drop at both ends of the valve, orifice plate, etc., and then checking the pressure drop and flow curve of the valve or orifice plate. The flow rate can be obtained through the pressure drop method, which has been widely used in HVAC water side systems and flow measurement instruments. The application of differential pressure switches in HVAC systems is mainly controlled based on the resistance and flow curves of HVAC equipment. Water side heat exchangers (sleeve type, shell and tube type, tube plate type, and commonly used plate heat exchangers), water filters, valves, and water pumps in HVAC all have their pressure drop and flow performance curves. As long as the measured pressure difference on both sides of the differential pressure switch is compared with the pre-set value, the flow can be accurately controlled. The differential pressure switch used for flow control in HVAC has the characteristics of accurate flow control, no additional resistance to the water system, no requirements for pipe diameter, and no water flow disturbance interference. It can replace any form of target flow switch. Compared with target flow switch, it can avoid false flow caused by pump cavitation and has very accurate reset flow and disconnection flow.

In some large equipment and machines, circulating water is usually used to cool the unit in order to ensure that the operating temperature of the unit is within a reasonable range. When the cooling water system malfunctions, if the water flow stops, it will cause the temperature of the unit to rise, affecting the normal operation of the unit, and in severe cases, it may cause the unit to burn out. Usually, a water flow switch is installed in the pipeline of the cooling water system to monitor the flow status of the cooling water in real time. Once the cooling water stops flowing, the water flow switch sends an alarm signal to the central control room for timely processing and to avoid accidents.

edit

There are many ways to detect the flow state of fluids. Generally, water flow switches can be roughly divided into three types. One is the early mechanical flow switch, also known as the baffle flow switch. Its principle is to push the baffle to deflect through the flow of water, and then trigger the micro switch action. The advantage of this mechanical flow switch is that it is easy to use and inexpensive, but the disadvantage is that the mechanical structure may experience wear and tear, and the action may not be very stable in poor water quality; One type is a thermal flow switch, which operates on the principle that the amount of heat carried away varies depending on the size of the liquid flow. By detecting the magnitude of heat loss, the flow of water can be monitored. The advantage of this water flow switch is that it has no movable parts, no wear and tear, greatly enhancing its lifespan and stability. The disadvantage is that it is slightly more expensive than mechanical ones; The last type is the differential pressure flow switch, which innovatively controls the flow rate accurately based on the pressure drop and flow curve of the heat exchanger, without causing any pressure drop to the air conditioning system.

Infrared water flow switch

edit

function and role

Also known as infrared water flow sensor, it is applied to the newly emerging high-tech industry in the water heater industry, namely the inlet of thermal electric water heaters, to detect the incoming water flow into the instant electric water heater and control the start and stop functions. Especially suitable as a matching device for constant temperature instant electric water heaters, it can timely transmit the detected inlet flow rate and temperature to the control system, achieving the goal of rapid constant temperature. It is also suitable for traffic detection needs of similar products.

Product Description

Infrared flow sensors are installed at the inlet end of products such as water heaters to detect the inflow rate. When water flows through the product, the impeller rotates and its speed changes with the flow rate. The infrared flow sensor outputs corresponding pulse signals to the controller, which issues corresponding commands based on the size and on/off of the water flow rate. The internal design of this product adopts a physical principle structure and has the function of anti backflow signal, which eliminates the dry burning phenomenon of signal generation in the case of water flow backflow; Due to the nature of product design, the control of magnetic cores is not used, which can effectively prevent magnetic impurities in water from adsorbing onto the impeller. The long-term use signal will not change with the prolonged use of the product. In addition, without a magnetic field as a signal source, the shaking of the impeller does not affect the strength of the signal, so the gap between the impeller and the housing can be increased to ensure that the impeller will not stick or get stuck due to poor water quality during long-term use.

Within a unit flow rate, the more pulse parameters emitted, the higher the accuracy and consistency of the product. When the infrared flow sensor has a flow rate of 1 liter/minute, it emits about 20 pulse signals per second and can emit about 1200 pulse signals per minute.
