Product Description:

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:Pressure switch and electromagnetic valve operating principle
Simply put, the pressure switch is a switch, as long as its inlet pressure exceeds its set value, you can open or the pressure signal into electrical signals to control the work of other components. The electromagnetic valve is to use the electrical signal to control the work of the spool, as long as the access to a certain current, you can achieve changes in the direction of liquid flow, thus controlling the commutation of the implementation of components. The source of the electrical signal can be a pressure switch or a trip switch.
Q:Can the pressure switch of the pressure tank be installed with the inlet pipe?
Can not, when the water into the water pipe will have a certain pressure led to the pressure of your pressure can not be measured.
Q:Home tap water self-priming pump work in the pressure switch in the contact da da da frequent contact,
Automatic switch in the spring I have been adjusted, whether to install the check valve and pressure? To answer Do not know how your pump is installed, the pump installed in front of the water pipe? Whether the water supply is caused by the municipal pipe network or the kind of water supply in the village? Self-priming pump has a feature that is automatically empty the suction pipe gas. Therefore, if you adjust the pressure difference after the situation you also said that it should check whether the import pipe leak. If the leak pump will work for a while to empt the leak into the steam, the performance is about what time off the water, so check the leak is non-critical, especially the joint seal to carefully check the bolt. You first try to try it! If your home is rural rather than municipal pipe network, then the pipe network will be there, there is trouble. But the check valve is of little significance. Not yet welcome to ask!
Q:Switch mechanical pressure switch and electronic pressure switch what is the difference
Electronic pressure switch is a first-class quality of a three-in-one product, which sets the liquid crystal pressure gauge, mechanical pressure switch and pressure transmitter as a whole. It is through the welding 316l diaphragm pressure, through the pressure sensor to convert the physical signal into electrical signals, amplification and processing as a standard analog signal output or solid state relay output. The product itself has a self-diagnostic function, and because it is an integrated product, anti-jamming capability and seismic strength increased significantly
Q:What is the pressure switch inside the rice cooker?
Rice cooker pressure switch, in fact, is to increase the pressure inside the pot, increase the boiling point, such as water is a hundred degrees on the boiling, and then how will not heat up again, only evaporation, but this is a standard atmospheric pressure, if increased Pressure, the boiling point may reach one hundred and one, that is to say that the pressure switch is to improve efficiency, make rice cooked faster,
Q:How does the air conditioning pressure switch check?
Low-voltage switch, not connected in the system, it should be disconnected High voltage switch, not connected in the system, should be closed
Q:Car 4-wire air conditioning pressure switch principle, 4 lines were then received there, and the role.
Low-voltage switch control air conditioning pump work or not, and high-voltage switch is to control the high-speed fan. Please refer to the 2 valve and 5 valve air conditioning system circuit diagram. Four-wire pressure switch works are the same, About two high and low pressure switch, the upper and lower pressure switch;
Q:Self-suction pump without pressure switch control can be
Understand the circuit can be modified, do not understand the circuit can simply plug the pressure switch to the maximum pressure (but should pay attention to when the water is not the time to pull the plug to prevent idling),
Q:What is the difference between a pressure switch and a pressure transmitter?
Pressure switch: When the system pressure is higher or lower than the rated safety pressure, the sensor inside the disc instantaneous movement, through the connecting rod to push the switch connector connected or disconnected, when the pressure dropped to or rise rated recovery The switch is automatically reset, or simply say that when the measured pressure exceeds the rated value, the free end of the elastic element displacement, directly or after comparison to push the switching element, change the switching element on-off state , To achieve the purpose of controlling the measured pressure. The pressure switch uses elastic elements such as single-ring spring tube, diaphragm, diaphragm and bellows.
Q:Fire automatic sprinkler system pressure switch in the role of pipe network and working principle?
The pressure switch is usually located in the top of the wet alarm valve buffer, when the sprinkler action, the wet alarm valve is the top of the water flow, all the way into the buffer water, and then start the hydraulic alarm, and flow to the pressure switch.
