The solenoid valve is composed of a solenoid coil and a magnetic core. When the coil is energized or de-energized, the operation of the core will cause the fluid to pass through the valve body or be cut off to achieve the purpose of changing the direction of the fluid. The electromagnetic component of the solenoid valve is composed of a fixed iron core, a moving iron core, a coil and the like, and the valve body portion is composed of a slide valve core, a sliding valve sleeve, a spring base and the like.

The electromagnetic components of the electromagnetic valve are composed of a fixed iron core, a moving iron core, a coil, and the like, and the valve body portion is composed of Spool, slide sleeve, spring base and so on.
After a long period of operation of the industrial chiller, it is normal for the parts to wear occasionally. If the solenoid valve of the chiller does not work, it may affect the operation of the switching valve and the regulating valve, thus affecting the operation of the entire chiller. Therefore, the operator of the unit should regularly check and record relevant data to detect problems in time. Solve the problem.
The common faults of solenoid valves are as follows:
1. The power supply voltage is too low, so that the solenoid valve cannot be normally opened and operated;
2, the circuit is in poor contact, that is, the circuit breaker or coil short circuit, so that the solenoid valve can not work, can be tested with a multimeter;
3. The installation direction of the solenoid valve is reversed, that is, the flow direction of the fluid is opposite to the flow direction required by the solenoid valve, so that the valve closing is not strict;
4, the solenoid valve chip has dirt, so that the chip is stuck, causing the closure is not strict or can not be closed;
5. The pressure difference between the inlet and outlet of the fluid is greater than the valve opening capacity, so that the solenoid valve cannot be opened;
6. The sealing gasket of the solenoid valve is damaged or the sliding valve is worn to cause several cavity helium gas, which will cause insufficient air pressure, which makes the forced valve open and close difficult.
Although the solenoid valve is only a small and small accessory in an industrial chiller, its role is unmatched. Therefore, Dongyuejin chiller factory mainly uses the American ALCO brand solenoid valve to ensure the safety and ensure its safety.

Planar beam loadcells, also known as planar force sensors, are used in low profile solutions where space is limited. These loadcells can be used as single or multiple loadcell structured platform scales.
Applications with planar beam loadcells
Most of the applications using planar beams are suited with 3 or 4 pieces for each application. which are used for point-of- sale scales/weighing systems in the 10 to 400 pound range. The low profile weighing equipment can be found in many different applications like medical applications (hospital bed and chairs, baby scales, incubators), checkout counters, agricultural devices, retail scales, bench scales and many other weighing devices.
