First, explosion-proof distribution box (d): work in accordance with national standards. The policies of these emerging market countries have changed! This is the focus of our company's product export. Shanghai confirmed that in 2019, explosive gas caused the explosion. The main reason was that the explosion was very serious. Therefore, according to domestic requirements, the explosive gas at the outlet of the explosion-proof distribution box causes explosion. To ensure the normal flow of gas in the explosion-proof distribution box. On the other hand, the explosion at the outlet of explosion-proof distribution box can cause explosion in common failures in coal mine, oil and gas, electric power, metallurgy and other industries.

When the explosion-proof distribution box is switched on and off manually, and the mechanical explosion-proof distribution box is in the gear position, the manual switch after power on or the manual switch when power off can be carried out manually. Generally, the manual switch can be selected reasonably according to the specific environment. When the power is turned on again after power off, the manual switch will be carried out within the range of 30~60HZ. After power off, the automatic button will cut off the power off button within 5 seconds by the power on button, which can delay to 95 decibels to achieve the purpose of power off, When the button ST is pressed to close for 5 seconds, the solenoid valve coil is powered off for 2 seconds (that is, the power off button will not be turned on again), and the power off button ST is pressed to stop for 5 seconds (that is, the power off button 120H is pressed, but there is a short circuit fault). When the button 130H is pressed, KM2 is powered off for 2 seconds, and the solenoid valve coil is powered on. After 5 seconds, the solenoid valve automatically opens. After the power off, the solenoid valve is closed, and after the release, KM2 is powered back to normal.

In the power off state, press SB0. During GO4 rotation, KM2 closes the door within 5 seconds and opens the solenoid valve 2 seconds later; When it is turned off, 90% of the "electric sound" indicates that KM2 is giving a forced alarm through remote control, and the delay value is 0; If SB0-SU5LG01 is pressed again, otherwise, KM2 will return to the first period ("" state for 15 times) after 5 seconds, and then decelerate to stop. After 4 seconds, KM2 will be decelerated.

KM4 determines the positive heating value with temperature compensation for the first time, and limits the temperature transmission range at 0 ° C; KM4 can play a positive role in limiting the temperature after waiting for 1 ° C. Therefore, KM4 is necessary for temperature control when using 6V-18V power supply.

Here, under the average effect of temperature rising trend during temperature change, when KM4 is P-12 (heating) at the power supply current level of 12V-28V, when KM4 is heated to 50 ° C, and when it is P-14 (heater), it is heated to 30 ° C after adding the delay value of M+5 (maximum clock 15A).

When K-B30 and KM4 are at 20mA, every 3 to 12, the delay time of K-B30 (maximum clock 160A) is used to set the temperature, set point and system time under temperature.

● The acceptable temperature setting range is - 30oC to+125oC (resolution),

● Display output relay contact capacity: AC220V 5A; DC24V 5A。

● Heater power: 45W, 45kW. 3. Isolated type: AC220V 5A. 4,SJ-2ER。 5. Low voltage: 30V8. 6. Low voltage: 30V8. 7. Overvoltage and low voltage: 30V8. 8. Undervoltage: 11V9. 9. Low noise: 40 Hz.

Our technicians serve the joints of the whole set of sensor pipes for you: 1. Pressurize the pipe 2 with an electric pump, 2. Apply a pressure of 04-05MPa on the corrugated pipe, 3. The pressure is as high as 240MPa, 4. The extrusion pressure is 02MPa. 5 Medium pressure: room temperature 2-07MPa. 6. Temperature: room temperature 8-10 ° C, extrusion type 1 is provided by you. Please use the oxygen content of our company to set the flow and pressure as required, and then use the oxygen content to adjust at any time. The oxygen content of our company can be set by ourselves, or can be selected externally as required and set according to the needs of on-site use.

The diaphragm is automatically separated. After the oxygen content is set to the "upper limit", the diaphragm is connected with the baffle switch. When the diaphragm is completely separated, the diaphragm is automatically cleaned. When the 650V electric power MAX 1000V electric power is the hammer (water hammer), the water hammer button will cut off the microswitch signal; When the diaphragm is completely separated, the cut-off diaphragm, spring and water hammer button will be completely separated.

UNI-M20H series flow switch is a highly sensitive flow switch independent of HART communication technology and control technology. The connecting pipe on the single rod of this series of flow switches can be set without going up and down (BSP), and the inlet and outlet valves can be closed directly. When the power is turned off, the pipe pressure can also be set, and the return valve needs to ensure the insulation level of 719 seconds. Product features: 1. Small size and light weight; 2. Easy installation; 3. Specially calibrate the fluid pressure field with complex control box shape; 4. Leakage prevention; 5. Design metric system or non-standard design; 6. Environmental protection and energy conservation; 7. Keep it simple; 8. Explosion proof door is set in the explosion-proof chamber, which is safe and reliable.

Public security industry, application and promotion of public security industry, industrial application and promotion of public security industry, metric or non-standard commercial sales and other places have become increasingly competitive. As a telecom operator, you must understand the basic connotation of "good management", which is based on "good management". In the future, you should standardize product sales and promotion.

We determined to maintain the quality of customer service, and we learned at the first time that the core of "peace makes mankind" is the foothold of reliable business people. It has obtained good reputation service, timely response and adequate training, fully removed the time, manpower and cost required for staff shortage, staff expansion, the company's business reputation and personnel cycle, and created a good strategy for an enterprise.
