Product model: MZS
Product features: cardiac MNS (MZS) type low voltage switch equipment (hereinafter referred to as low voltage switchgear) is our company according to our country's low village, the development trend of complete switchgear in the appliances in the selection of components and improvements on the structure of cabinet put oneself in another's position, and register the product.The product fully meet the original electrical performance and mechanical properties of MNS product technical requirements.
Derive the low-voltage switchgear is suitable for use in ac 50 ~ 60 hz, rated voltage 660 v and below the power system, as power generation, transmission, distribution, power conversion and power consumption equipment control.
Derive the low-voltage switchgear in addition to the general land use, after special processing can also be used for offshore oil drilling platform, and in nuclear power plant.
Product standards: cardiac GB7251 low-voltage complete switch equipment and control equipment.
Cardiac JB/T9661 low-voltage withdrawable switchgear.
Has it - 1 low-voltage complete switch equipment and control equipment.
Environmental conditions of use: cardiac ambient temperature is not higher than + 40 ℃, and the average temperature is not higher than within 24 h + 35 ℃, the lowest temperature is not lower than 5 ℃.
Is left when the relative humidity at the highest temperature is + 40 ℃ not more than 50%, at lower temperature, allowing a higher relative humidity (example: + 20 ℃ at 90%).
Cardiac altitude does not exceed 2000 m.
Has allowed in 25 ℃ ~ + 50 ℃ temperature under the condition of transportation and storage, and allows the temperature does not exceed + 70 ℃ within 24 h.
Derive seismic intensity less than 9 degrees.
Technical parameters: derive vertical busbar rated current: single-side or double-side operating draw-out MCC is 800 a, portable for 1000 a;Tank depth 1000 mm single operation of MCC is 800 ~ 2000 a. 
Cardiac protection class IP54 due to reduced capacity in severe cases, it is not recommended. 
Product structure: cardiac low-voltage switchgear basic frame for the combination of the fabricated structure, the frame of the whole structure through galvanized processing, 8.8 by tapping screw or hexagonal screw strong connected into the basic frame, then the need to change according to the plan, and combined with the corresponding door, sealing plate, diaphragm, mounting bracket and busbar, functional units and other parts, assembled into a complete low voltage switchgear, switchgear components in size, the size of the compartment for modular (modulus E = 25 mm). 
Cardiac draw-out MCC has five kinds of the size of the drawer, they respectively are 8 e/e / 4, 8, no. 2, 8, 16 and 24 e e e.Eight e/e / 4 and 8, no. 2 two kinds of the structure of the drawer is made of flame retardant plastic and aluminum molding (4 8 e / 4 or 2 8 e / 2 form a e the height of the interval).Functional units compartment of the total height is 72 e.

Q:What is the difference between a pressure switch and a differential pressure switch?
The main difference between the pressure switch and the differential pressure switch: 1, the structure is not the same: (1) pressure switch with high stability, high precision pressure sensor and transmission circuit, and then through a dedicated CPU modular signal processing technology to achieve the media pressure signal detection, display, alarm and control signal output. (2) and the differential pressure switch is composed of two high sensitivity of the pressure element, if both change, it will cause the switch mechanism to control the equipment such as motor-driven valves. The switch mechanism provides the SPDT non-fast acting (floating) action, so the shared movable contact will touch one of the two fixed contacts, or stay between the two (no contact).
Q:9 Yang electric pressure cooker pressure switch in which position
Electronic temperature control technology without pressure switch, a pressure switch is generally placed in the bottom of the pot insulation cover, remove the base cover will be able to see.
Q:Pressure switch on a pair of normally open point how to reach the alarm and direct Kai pump
B, when the double-contact pressure switch, the problem is simple, as long as a group of contacts wiring to the spray pump control cabinet, another group of contacts connected to the alarm host. Now the actual engineering applications, double contact pressure switch with more and more.
Q:Is the booster pump pressure switch available at the repair shop?
Directly looking for aftermarket? Responsible for the sale of units are generally sales units.
Q:Is the pressure switch used?
For the pure mechanical deformation caused by micro-switch action. When the pressure increases, the role of different sensing pressure components (diaphragm, bellows, piston) deformation, will move up, through the railing spring and other mechanical structure, and ultimately start the top of the micro-switch, the electrical signal output. Vacuum switches, differential pressure switches and temperature switches can be used in the following areas: chemical plants, oil pipelines, refineries, pulverized coal and grain dust treatment, clean gas pipelines, gas cushioning systems, tanks and pressure pumps, compressors and steam turbines The
Q:I would like to use a two-point output pressure switch to achieve high pressure stop pump, low pressure pump, I would like to ask how the line should be connected, the best wiring diagram, thank you.
This is very simple. Low pressure when the node connected, then you through the middle of the relay often open the point to lock the node,
Q:Does the direction of the pressure switch switch the direction of heavy?
This car is nothing wrong, never been to the 4s shop done maintenance, all I give this car for oil or something.
Q:Fire sprinkler system pressure difference, the pressure switch in the fire control center alarm, but the hydraulic alarm did not alarm
B, when the double-contact pressure switch, the problem is simple, as long as a group of contacts wiring to the spray pump control cabinet, another group of contacts connected to the alarm host. Now the actual engineering applications, double contact pressure switch with more and more.
Q:What is the role of the fire engine pressure switch?
The input module, which is called a monitoring module, is used to detect the working status of the equipment. It is usually monitored to use the normally open signal device. Once the device is being monitored and normally closed, the alarm information of the device action is sent to the host. ?? Pressure switch: When the alarm valve action, alarm pipe water, tube pressure is greater than the set value, the switch action, to the system feedback alarm valve work. ?? Signal valve: In order to avoid misuse of personnel, resulting in the valve closed, the system can not work, so the valve installed on the signal feedback device to avoid misuse
Q:How does the compressor start the pressure switch to protect it?
If the low-voltage protection switch action, in most cases the refrigerant has been leaked.
