| Â The problem of Jiang Zhong Apartment Miss Mao |
Installed electric water heaters at home, back to open, ready to take a bath in the evening, obviously the indicator light is also off, how every time when washing is quickly turned cold, summer is okay, now are late autumn, day by day Cold, can not be dragged on again, would like to ask what the supervision of the master, I feel no problem with the water heater, ah, but also very new, is not installed in place or how?
| Â Supervision question |
Water heater burning hot water? Have you ever encountered such a situation? Obviously, the indicator light has gone out, and you have spent enough time to burn hot water. When you wash it, it is still hot and cold, or just before it is washed, the water starts. Chilling, under normal circumstances, the first thing to consider is whether the water heater has a problem. If there is no problem, then what part of the installation did not pay attention to, and today to Miss Mao analysis of the installation of water heaters need to pay attention to what links you Did you see it?
First, install the filter
Instant water heaters must be equipped with a strainer at the inlet, as there is a small amount of debris in the tap water to avoid trapping float magnets (dry burn, no heat) or clogging the shower (the water is getting smaller and smaller). If the filter is clogged, the flow rate will decrease, the water will become smaller, and the floating magnetic heater will not heat. Use the filter after a period of time to remove it for cleaning.
When installing the water heater, the staff must remember to check whether the "floating magnet" is at the bottom, so that it is free to move to ensure the normal use of the water heater. Because the floating magnetic is a hydroelectric linkage switch, open the water valve to automatically heat, turn off the water to stop heating, if there is debris stuck magnetic float, water heater will appear dry or not heating phenomenon, clear the floating magnetic debris, in order to normal jobs.
Third, without mixing valve
Instant electric water heaters do not require the use of mixing valves, because if the mixing valve is used, cold and hot water will mix and flow out at the same time. In this case, the flow of hot water will become smaller, resulting in the water temperature of the water heater being too high. Temperature (thermostat action), the phenomenon of hot and cold water changes. The staff should inform the customer who uses the mixing valve to switch on the water directly to the hot water side without mixing the cold water, so that the service life of the product will be longer and it will not be easy to foul.
Fourth, control the flow of water
When installing the water heater must use the factory equipped with a special shower, water heaters in normal working conditions, can adjust the water flow or increase the high-grade water temperature. The average user does not have the habit of controlling the flow of the faucet, so that the water temperature does not reach the predetermined effect.

Water heater appliance installation
The liquid level transmitter can convert the changes of various level parameters into analog signals, and transmit them to the control room remotely for centralized display, alarm or automatic control of secondary instruments or computers. Its good structure and installation method can be applied to the continuous detection of liquid level, material level or material level under special conditions such as high temperature, high pressure, strong corrosion, easy crystallization, anti-clogging, anti-cold junction, and solid powdery and granular materials. , can be widely used in detection and control in various industrial processes.
Liquid level transmitters can be applied to liquid Level Measurement and control in industrial sites, rural water supply and sewage treatment, petroleum, chemical industry, power plants, hydrological monitoring, reservoirs, dams, hydropower construction and other fields of liquid level measurement and control. Liquid level transmitters have input type, straight rod type, flange type, threaded type, inductive type, screw-in type, floating ball structure design, with anti-blocking type design, simple device, convenient use and strong interchangeability , The high-quality sensor has high sensitivity and fast response speed, accurately reflects the slight changes in the flow or static liquid level, and has high measurement accuracy.
Advantages of Level Transmitters
1. The device is simple, easy to use, and has strong interchangeability.
2. It is suitable for measuring the liquid level and interface of the liquid medium in the container. In addition to on-site instructions, it can also be equipped with remote transmitters, alarm switches, and complete detection functions.
3. The reading is intuitive and eye-catching, and the direction of the observation indicator can be changed according to the user's needs.
4. The measurement range is large, not limited by the height of the storage tank.
5. The indicating mechanism is completely isolated from the measured medium, with good sealing performance, high reliability and safe use.
6. Simple structure, convenient installation, convenient maintenance, corrosion resistance, no power supply, explosion-proof.
7. The high-quality sensor has high sensitivity and fast response speed, accurately reflects the slight changes of flowing or static liquid level, and has high measurement accuracy.
8. With intrinsically safe explosion-proof and isolated explosion-proof capabilities, it can be used in various dangerous places.
9. With anti-blocking design, it can realize the measurement of the liquid level of paste medium.
10.100% equal division scale, LED/LCD indicator head, very convenient to read on site.
11.4~20mA two-wire signal transmission, strong anti-interference ability and long transmission distance.
12. Exquisite and unique zero point, full scale, and nonlinear compensation ensure the accuracy and stability of the instrument within the range of operating conditions.
13. The Pressure Sensor directly senses the liquid level pressure and is not affected by the foaming and accumulation of the medium.
14. Wide range of tested media can be used, such as oil, water and paste, with certain anti-corrosion ability.
Classification of liquid level transmitters
1. Single flange liquid level transmitter
Single-flange liquid level transmitters have flat flanges and flange liquid level transmitters with insert barrels, both of which are suitable for single-flange liquid level transmitters that use the gravity of the medium to be measured to measure the height of the liquid level. For medium with high viscosity and easy crystallization, it is generally used in open containers or equipment installations.
2. Double flange liquid level transmitter
The double-flange liquid level transmitter is a Differential Pressure Transmitter, which provides a reliable measurement method to prevent the measured medium from directly contacting the isolation diaphragm of the transmitter. The main features are the need to isolate the high-temperature medium from the transmitter, the measurement medium has a corrosive effect on the sensitive components of the transmitter, the suspension liquid or high-viscosity medium, the measured medium solidifies or crystallizes due to changes in the environment or process temperature, and the measured medium is replaced It needs to be strictly purified to measure the first class. Double flange liquid level transmitter is mainly used in the measurement of liquid level in sealed pressure vessels.
3. Submersible liquid level transmitter
The submersible liquid level transmitter has rod type and arm type. Its principle is based on the principle that the measured liquid static pressure is proportional to the height of the liquid. It uses the piezoresistive effect of diffused silicon or ceramic sensitive elements to convert the static pressure into electricity. Signal. After temperature compensation and linear correction, it is converted into 4~20mA current signal output. Due to the characteristics of this transmitter, such as convenient installation, strong adaptability, etc., it can perform high-precision measurement from water, oil to paste with high viscosity, and is not affected by the foaming and accumulation of the measured medium. It is generally used in open Devices for mouthpieces or equipment.
