Wall drain method: repair the original structure of the waterproof line structure waterproof, its function is to make the water dispersed.
When the cavity structure is partially destroyed, the use of restorative repair works well.
Repair with waterproof material: This method is suitable for a wide range of applications, ie, the use of oil-soluble or water-emulsion-type waterproof materials for caulking or brushing in the interior of rainwater.
Take waterproof measures on the outer side of the outer wall panel.
The method of water blocking inside the outer wall is to adopt waterproof measures on the inner side of the outer wall, and to block rainwater intrusion through waterproof materials.
Second, exterior wall architectural paint construction: new wall paint construction: the construction of the outer wall of the coating requires a sufficient period of conservation, the new water mortar concrete surface must be a reasonable curing time, so that 'spike alkali', fully dry . The surface of the bottom layer should be dry, solid, and firm, and there should be no defects such as sanding, cracks, and looseness.
Construction method: The exterior wall coating should not be used to scrape putty on large areas, and the putty layer should not be too thick. The material is made of polymer cement putty. Generally used once again primer, two times overcoat construction. According to the quality requirements of the project, the number of overcoatings can be increased. The painting construction is generally performed from top to bottom. Each time brushing should be bounded by a dividing line, a wall surface, a junction between the yin and yang corners, or a falling water pipe.
Operating tools: Roller, brush or air spray and airless spray are generally used.
Maintenance refurbishment: The use of paint to decorate the surface of a building, the biggest advantage is that it can be refurbished in a certain period of time, and the general maintenance of the building is generally done in 4-5 years. A comprehensive survey of the renovation of the external wall before construction, the development of a construction plan.
The above is the introduction of the outside of the wallboard waterproofing measures, the steps are very clear, it is not difficult to operate. Hope to help you.
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.
