The characteristics and working principle of the refrigeration solenoid valve

The refrigerating solenoid valve is suitable for non-pressure difference or low pressure system. The pulse solenoid valve inputs the coil of the solenoid valve into the forward pulse signal through the wire, and the working magnetic flux generated by the coil makes the moving core suck and open the valve.

Characteristics

One: applicability

The fluid in the line must match the medium calibrated in the selected solenoid valve series.

The temperature of the fluid must be less than the calibration temperature of the solenoid valve selected.

Solenoid valves allow liquid viscosity to be generally below 20 CST, and greater than 20 CST should be noted.

Working pressure difference, the maximum pressure difference of the pipeline should be less than 0.04MPa, such as ZS, 2W, ZQDF, ZCM series and other direct-acting and step-by-step direct-acting type; when the minimum working pressure difference is greater than 0.04MPa, the pilot type can be used. Differential) Solenoid valve; the maximum working pressure difference should be less than the maximum calibration pressure of the solenoid valve; the general solenoid valve is one-way work, so pay attention to whether there is a back pressure difference, if there is a check valve installed.

1. A combination of direct-acting open-valve and pilot-operated open-valve two-piece recoil-type special structure;

2. The zero pressure can also open the main valve, the low pressure difference flow is large, and the application range is wide;

3. Different mediums are used, and the targeted sealing is used to improve the rationality of the solenoid valve;

4. The valve plug adopts a molding process to further improve the life and reliability of the solenoid valve;

5. The use of precision cast copper body, the appearance is exquisite and beautiful.

working principle

The refrigerating solenoid valve is an automatic basic component used to control the direction of the fluid. It is an actuator; it is usually used on mechanical control and industrial valves to control the direction of the medium to control the valve switch. There are closed chambers in the solenoid valve. There are through holes in different positions. Each hole leads to different oil pipes. The middle of the cavity is a valve. On both sides are two electromagnets. Which side of the magnet coil is energized and the valve body will be attracted. On which side, by controlling the movement of the valve body to block or leak different oil drain holes, and the oil inlet hole is normally open, the hydraulic oil will enter different oil drain pipes, and then the oil pressure will push the oil cylinder. The piston, which in turn drives the piston rod, drives the mechanical device. This controls the mechanical motion by controlling the current of the electromagnet. Only the electromagnetic valve is applied by the electromagnetic force to the iron core sealed in the magnetic isolation bushing of the electric regulating valve. There is no dynamic seal, so the external leakage is easy to block. The electric valve torque control is not easy, it is easy to produce internal leakage, and even the stem of the valve stem is broken; the structure of the electromagnetic valve is easy to control the internal leakage until it drops to zero. Therefore, solenoid valves are particularly safe to use, especially for corrosive, toxic or high temperature media. The solenoid valve itself is simple in structure and low in price, and is easy to install and maintain compared to other types of actuators such as regulating valves. What's more remarkable is that the self-control system is much simpler and the price is much lower. Since the solenoid valve is controlled by the switching signal, it is very convenient to connect with the industrial computer. In today's era of computer popularization and price drop, the advantages of solenoid valves are even more obvious.

Micro Coreless Motor

Micro Coreless Motor product introduction:

Micro Coreless Motor in structure broke through the traditional motor rotor structure, USES is no rotor, also called the hollow rotor cup type.Hollow cup motor with brush and brushless divides into two kinds, brush with hollow cup motor rotor iron core, without brush hollow cup motor stator iron core.Winding adopts delta connection.


Coreless Motor


Function: fast speed, suitable for aircraft model, electric toothbrush,USB fan and other products.
Coreless Motor

Characteristic: the volume is 6MM 7MM fast.
Features: small size, fast speed, dc high speed motor starting voltage 0.6v is not possible for other motors.Wear shaking head, strong vibration feeling.

Coreless Motor


Operating temperature range:

Micro Coreless Motor should be used at a temperature of -10~60℃.

The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.

If a Micro Coreless Motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.


Storage temperature range:

Hollow cup motor should be stored ta a temperature of -15~65℃.

In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.


Service life:

The longevity of hollow cup motor is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.

●Use with a load that exceeds the rated torque

●Frequent starting

●Momentary reversals of turning direction

●Impact loads

●Long-term continuous operation

●Forced turning using the output shaft

●Use in which the permitted overhang load or the permitted thrust load is exceeded

●A pulse drive ,e.g.,a short break,counter electromotive force,PWM control

●Use of a voltage that is nonstandard as regards the rated voltage

●Use outside the prescribed temperature or relative-humidity range,or in a special environment.

●Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.
