- Q: Our unit has a 2.2kW water supply motor, running with EV1000. How to control according to the remote pressure gauge? Is to control the pressure within a certain range. Read the instructions, there is a process closed loop control parameters, but not quite understand.. please expert advice. It's best to say what parameters you need to change.Added 15 points to answer satisfaction.
- Method for controlling water pump by remote pressure gauge by Emerson frequency converter:The remote contact signal is first transmitted into the PLC, and after the arrangement, the starting signal of the frequency converter is uniformly sent through the PLC. PLC can judge or delay method to control the frequency converter start and stop pump action, to achieve not only switch control water pump, but also soft soft stop pump effect. As for the wiring, relatively simple, PLC contact is connected to the frequency converter to start, stop contact. Of course, the water pump protection circuit is completed. Logical control is done by PLC.Note: it is not suitable to control the frequency converter directly with the contacts of the remote pressure gauge. First of all, the contact jitter, will damage the inverter, and secondly, the number of contacts is not enough.
- Q: The pressure gauge is red, yellow and green to indicate the pressure. When the needle points to the green area, what does it mean?
- The pressure of the lift extinguisher is designed according to the maximum pressure of the storage tank. Work pressure is defined as the internal balance pressure of a fire extinguisher rated and filled 20 hours after being placed in the environment for 18 hours. The situation you describe is qualified. Domestic fire extinguishers generally pressure gauges are divided into three grades, both three colors. The pointer undervoltage condition in the red zone, in the middle of the green zone generally reach fire extinguishers work pressure, and in the yellow zone that is overpressure, each fire extinguisher has its own working pressure, pressure is too low will affect the use of.
- Q: What do you think of the air conditioner liquid pressure gauge? How much pressure does it add?
- The number corresponding to the pressure in the fluorine 22 pressure gauge refers to the evaporation temperature of fluorine 22 under the corresponding pressure. Any Freon 22 air conditioner operating in a refrigeration environment, the ambient temperature of 25 degrees to 45 degrees, the pressure should be 0.45-----0.6MPa.Outside the red circle, -30 to 350LB/IN2, this is the British unit of force, and the inside is -0.1 to 2.5MPa, this is what we often say pressure, unit is MPa (MPa).Now the table is in the position of no pressure, that is to say, the table pointer is on the 0 bit. Under normal operating conditions of the air conditioner, the meter should point to the 0.5MPa. 0.1MPa is approximately equal to 1.0197 kg / cm, 2 (kg/cm2) =0.987 atmospheric pressure (ATM), that is to say, the normal operating pressure of the air conditioner is 5.0985kg/cm2.
- Q: The indicator of the extinguisher pressure gauge points to green, indicating whether the extinguisher pressure is normal or not?
- Remember, red bottle, green, normal green bottle, red normal oxygen bottle
- Q: How do you recognize the pressure gauge?
- To recognize the pressure gauge units, the general units are Mpa, mbar, bar, PA, and so on. Then see where the pointer points.
- Q: What is the range of use of a pressure gauge? Why is it at its measuring range of 1/3-2/3?
- Pressure gauges are common range instruments, the statutory use of membrane pressure gauges should be used. (2) when the pressure of the pressure is stable, the normal operating pressure shall be at 1/3 2/3, 2 of the upper limit of the measuring range of the instrument
- Q: 11 kw frequency conversion, plus an electric contact pressure meter to control a water pump motor. It requires low 4 pressure, high point and 8 pressure. How can I connect it?. Manufacturers to the approach of water pump to low-end wine began to maintain pressure, but not rising in opposition, the motor does not stop, what is the reason?. Also, I bought the electric contact pressure meter, there are 4 terminals, red at the bottom of the electrical contact, green in the middle, yellow in the above, the producer said I received the wrong end of the public, but I have three lines have been inverted. The motor is not automatic stop, master pointing what happened
- You can use a multimeter before starting to start out a line close point for inverter (low voltage to low voltage pointer must be required to adjust), but do not use inverter panel wiring, control operation, until the pointer pressure gauge pressure to coincide, volume out of a closed point, so that you can find public line. Then access to the converter can be put into normal operation.
- Q: How do you see a vacuum gauge?
- The units on the vacuum pressure gauge are bar, MPa, kPa, and the readings are mainly visible;The vacuum meter is divided into pressure vacuum meter and vacuum pressure gauge. Vacuum pressure gauge: Instrument Based on atmospheric pressure for measuring less than atmospheric pressure. Pressure vacuum meter: an instrument based on atmospheric pressure for measuring greater than or less than atmospheric pressure.There are two ways of expressing pressure. One is the absolute pressure, which is called absolute pressure, and the other is the pressure expressed on the basis of atmospheric pressure, which is called relative pressure. Since the pressure measured by most pressure gauges is relative pressure, the relative pressure is also called the gauge pressure. When the absolute pressure is less than the atmospheric pressure, the absolute pressure in the container is less than the value of one atmospheric pressure. Vacuum".They are as follows: the relationship between the absolute pressure = + atmospheric pressure relative pressure; vacuum degree = atmospheric pressure and absolute pressure; pressure units in China legal Pa (N/ m), known as Pascal, referred to as the PA. Since this unit is too small, it often uses its 10^6 times unit MPa (Zhao Pa).
- Q: What's in, Hg, VAC on the R134 air conditioner pressure gauge?
- In.hg stands for inches in mercury, and cm.hg stands for centimeter hg. VAC - vacuum
- Q: The difference and relation between the electric contact pressure gauge and the remote pressure gauge
- The use of the two is different. One is used to control the other, and the other is to send the signal to the farther end of the monitor.The electric contact pressure gauge consists of measuring system, indicating system, magnetic auxiliary contact device, shell, adjusting device and junction box (plug seat), etc.. The working principle of electric contact pressure gauge is spring pipe in the measuring system under the action of the pressure of the measured medium based on the force generated by the end of spring pipe corresponding elastic deformation displacement transmission rod through a gear transmission mechanism with the help and amplification by the fixed gear instructions (along with contact) by the measured value indicated in the table. At the same time, when the contact and set on the pointer (upper or lower) contact (break or close) instantaneous, resulting in the circuit control system can be switched on or off in order to achieve the purpose of automatic control and alarm.The remote pressure gauge is suitable for measuring the pressure of liquid, steam and gas which can not corrode the steel and copper alloy. Because the resistance transmission pressure gauge is arranged inside the sliding line resistance transmitter, so the measured values of two meters on electricity to far away from the measurement, in order to realize centralized monitoring and remote control. In addition, the pressure gauge is capable of indicating pressure in place so as to facilitate on-site inspection.
