Because there are so many brands and types of towerless water heaters on the market today, for those who have no experience in buying towerless water heaters, how to choose the right one is undoubtedly a very nerve-wracking issue. Then the editor of the Qi family will teach you the difference between the waterless material and the waterless one.
Which is better
1. Enamel carbon steel towerless water supply
In principle, enamel has the highest cost performance, moderate price, and long-lasting durability. However, during the long-term installation and use, its products have two flaws.
1. Because the sealed type has only a small mouth, the internal and external enamel levels of this product are very different. The external appearance is very good. Generally, there is nothing wrong. In fact, the enamel is processed after welding. Generally, it is very small, which will increase the difficulty of inner enamel. There will be dead corners or uneven enamel in a certain part. I have seen a lot of these products. This is all the case. The improvement method is to add a combination of flange and cushion to achieve internal and external consistency, but The difficulty of processing has increased, so the company has not implemented it.
2. Because it is an enamel product, x1bjb will have shortcomings during transportation, installation and use. At present, the packaging is not good. Generally, it is wrapped with a film and wrapped with straw rope. After a collision, it will cause the enamel to fall off and cannot be enameled twice. It cannot be repaired internally, and its service life is greatly shortened. In addition, during installation and use, especially in summer, special care must be taken not to be exposed to the sun. The consequence is that the internal temperature is too high. When water is supplied, due to the low water temperature, the cold and hot will increase. It causes internal enamel frosting, which will fall off in severe cases and the life will be reduced.
2. External spray paint and anti-corrosion carbon steel type towerless water supply
This type of product has been used for many years. The advantage is that the price is not high and it is easy to accept. However, the anti-corrosion function of this type of product will be reduced within 5 years of use. The thickness of the plate used for household type is generally 3 meters, which is long. The phenomenon of water leakage will need to be repaired, and it will rust when the external time is long. Therefore, I suggest that this product is best to choose a thicker product, which will extend the service life. Once the external rust, it needs to be polished. Paint, prevent trouble, this type of product is suitable for most people.
3. Stainless steel water supply without tower
The price of such products is relatively high. The material is different, there are 201, 202, 304, 304 is currently the best on the market, but the price is higher than 201 202, so many manufacturers choose 201 or 202 to sub-fill it, which requires the customer ’s eye-catching eyes The product should pay special attention to the welding method. The manual welding method will cause water leakage after use. You must find the machine welding. This can be distinguished by eyes. The machine welding is very smooth and round. The manual type can be felt by hand. There are irregularities.
Advantages of towerless water supply
1. Significant economic benefits: The use of this equipment can eliminate the need to construct water towers or roof water tanks, which not only reduces the construction cycle of the project, but also solves the shortcomings of high project cost, and overcomes the shortcomings of large air pressure fluctuations and frequent pump startups. Office.
2. Strict design: The equipment adopts water pump frequency conversion constant pressure control, no matter how the water consumption of the system changes, it can keep the pipe outlet pressure constant.
3. Reliable operation: The equipment adopts frequency converter and domestic high-quality water pump, with perfect protection function and automatic and manual conversion function, making the operation very reliable. And good performance, flexible control methods, anti-interference ability.
4. Efficient and energy-saving: The equipment can adjust the speed of the water pump according to the change of the user's water consumption, so that the water pump always works in the high-efficiency area, and the power saving effect is obvious, which can save 35% of the power than the constant speed water pump.
5. Simple operation: The device adopts full automatic control, PID adjustment, keyboard operation, and display of human-machine interface (text, numbers). The operator only needs to switch the switch of the electric control cabinet to realize the working conditions required by the user and realize the fully automatic unattended operation.
6. Complete protection function: it has perfect automatic protection functions such as overload, short circuit, overvoltage, undervoltage, phase loss, overcurrent, short circuit, water shortage and so on. Under abnormal conditions, it can carry out signal alarm, self-check, fault judgment, etc.
7. Small footprint and convenient installation: The whole set of equipment has only one set of water supply control cabinet and pump unit, which is very simple and convenient to install.
Daily maintenance of towerless water supply
1. Before removing the inlet valve for the first time without tower water supply equipment, the manhole cover, pressure gauge and safety valve should be installed. And close the sewage valve and the total stop valve to prevent the air in the supercharger from being discharged with the entry of water;
Second, the installation of this equipment should choose a well-ventilated, less dusty, non-humid place with an ambient humidity of -10 ℃ -45 ℃. Outdoor facilities for rain and lightning protection should be provided.
3. To facilitate equipment installation and maintenance, 80cm space should be left around the equipment, 1.5m space should be reserved at the manhole, and drainage trenches should be set around the ground.
4. After the site is selected, the foundation must be properly handled, and the tank support should be poured with concrete or masonry; after the initial setting of the base, the tank should be hoisted and stabilized, and then install the accessories and turn on the power.
5. When everything is normal, you can open the stop valve and use it. For more knowledge, see how to adjust the water pressure of the water supply. When the pressure drops gradually and reaches the lower pressure limit, the black needle and the red needle coincide; then the pump can automatically run water supply.
Summary: The above is what kind of good content is the towerless water supply introduced to you by the editor. I hope to help you effectively; if you have any good suggestions, partners, I look forward to communicating with the editor. For more information, please pay attention This website.
