川消講解如何調節消防壓力開關壓力

壓力開關是我們生活中經常使用的東西。有很多種開關我們不知道，比如壓力開關。壓力開關具有壓力檢測、顯示壓力尺寸、報警和控制壓力信號輸出的多種功能。今天川消小編為您解答：
Pressure switch is often used in our life. There are many kinds of switches we don't know, such as pressure switches. The pressure switch has the functions of pressure detection, pressure size display, alarm and pressure signal output control. Today, Sichuan Xiaobian answers:
壓力開關精度高，性能穩定。廣泛應用于石化、冶金、電力、供水等行業測量不同液體等表面壓力和絕壓。金寶和控制是一種智能檢測和控制儀器。
The pressure switch has high precision and stable performance. It is widely used in petrochemical, metallurgy, electric power, water supply and other industries to measure the surface pressure and absolute pressure of different liquids. Jinbaohe control is an intelligent detection and control instrument.
壓力開關的工作原理是，如果壓力開關系統中的壓力高于或小于初始設定的壓力值，壓力開關中傳感器中的光盤可以及時感應和報警，同時移動。通過與導桿連接，壓力開關的接頭可以連接或斷開。
The working principle of the pressure switch is that if the pressure in the pressure switch system is higher or lower than the initially set safety pressure value, the optical disc in the sensor in the pressure switch can sense and alarm in time and move at the same time. By connecting with the guide rod, the connector of the pressure switch can be connected or disconnected.
當壓力開關系統中的壓力恢復到初始設定的壓力值時，光盤可以及時感知，然后在瞬間恢復到原始位置，開關將自動恢復到原始位置和狀態。需要注意的是，我們需要了解壓力開關的調整方法。讓我們具體看看：
When the pressure in the pressure switch system is restored to the initially set safety pressure value, the disc can be sensed in time, and then it will instantly return to the original position, and the switch will automatically return to the original position and state. It should be noted that we need to understand the adjustment method of the pressure switch. Let's take a specific look:
1.選擇0.1~1.0Mpa的壓力控制器(JC-210，HNS-210)
1. Select 0.1~1.0mpa pressure controller (jc-210, hns-210)
2.旋轉頂部右側的壓力調節螺釘，將指針指示在0.8Mpa(8kg或8bar)的上限切換值。
2. Rotate the pressure adjusting screw on the right side of the top to indicate the upper limit switching value of 0.8MPa (8kg or 8bar).
3.旋轉頂部左側的壓力調節螺釘，使指針指示在0.3mpa標準尺上，下限切換值=上限切換值-開關壓差=0.8-0.3=0.5，為下限切換值。
3. Rotate the pressure adjusting screw on the left side of the top to make the pointer indicate on the 0.3MPa standard. The lower limit switching value = upper limit switching value - switching differential pressure =0.8-0.3=0.5, which is the lower limit switching value.
川消壓力開關主要包括常開式和常閉式。其主要特點是：采用螺紋快速接頭或銅管焊接安裝結構，安裝靈活，使用方便，無需特殊安裝和固定。插入式導線連接可供用戶選擇。密封不銹鋼傳感器。根據客戶需要的壓力在壓力范圍內制造。
Pressure switches mainly include normally open and normally closed. Its main features are: the use of threaded quick connectors or copper pipe welding installation structure, flexible installation, easy to use, without special installation and fixation. Plug in wire connection is available for users to choose. Sealed stainless steel sensor. It is manufactured within the pressure range according to the pressure required by the customer.
