Nowadays, the parking problem has been plaguing people's lives. Many first- and second-tier cities have started to increase the construction of parking lots to ease the current problem of parking. We often encounter congestion problems at the entrances and exits of parking lots, causing part of the congestion phenomenon. Because of the problem of our equipment itself, the other part is the problem that many people do not understand when installing parking systems.
There are many factors that need attention in the parking lot system: the choice of coil material, the shape of the coil, the number of turns of the coil, the length of the output lead, the method of embedding, and the installation method. If we buy a car park system that manufacturers have installed for us, these may be issues that we rarely care about, but if we install the parking system ourselves, we need to pay special attention to these issues such as the choice of the ground line. The installation of geomagnetic coils needs attention. Here we briefly introduce them.
First of all, the cutting of the inductive coil concave groove is performed with a width of approximately 5-10 mm and a depth of 30-40 mm, and a 45-degree chamfer is cut at the four corners to prevent the destruction of the sense coil with a sharp corner. At the same time, the coil lead should be cut into the same concave groove or other pipeline wiring to the roadside. The detector can be connected to the test run first. If it is normal, it can be sealed with cement mortar or asphalt. Secondly, in addition to the common wiring needs to pay attention to the wiring of the ground coil, it should also be noted that when there is a strong metal object under the road surface, the inductance of the coil will be significantly reduced, which will lead to lower detection sensitivity. Therefore, the number of turns of the coil should be lower than It is usually increased by 2 åŒ to compensate for the effects of strong metal. In addition, the best connection between the coil and the feeder should not be, if the conditions do not allow, the contact should be welded, and must be done waterproof treatment, otherwise it will seriously affect the stability and reliability of the car detector, in the use of long feeders When places or feeders are wired together with other wires, it is strongly recommended to use twisted-pair shielded cables as the feeder and ground the shield at one end connected to the detector.
As a supporting device in the parking lot management system, the geomagnetic coil is the same as the floodgate. It works uninterruptedly 24 hours a day. Its stability directly affects the operation of the parking lot. Therefore, it is installed and used. The parking lot management system must strictly comply with the requirements for the use of the equipment and prevent it from happening.

R22 Refrigerant Gas
R-22, also called HCFC-22, has been a refrigerant mainstay for many years. This
is suitable for a wide range of refrigeration and air conditioning applications
across a wide range of temperatures. Therefore it became the most common
refrigerant in many applications after the phase out of CFCs.
Zhejiang Zhonglan Refrigerants Co.,Ltd is a professional R22 refrigerants gas manufacture.
