1 Ultrasonic level gauge.

Instruments and equipment do not need to be calibrated. If there is an abnormality, you can check the flatness of the camera installation, the spacing of the spacing side wall, the abnormal support point, the slow secondary connection, the output signal of the remote control signal is appropriate, and the main parameters are appropriate.

7 kinds of environmental protection equipment maintenance skills that the master doesn't know.

The maintenance scheme is as follows:

The inspection of the composite glass measuring electrode is generally once every 3 months with self-flushing, and once a month without self-flushing, mainly to check whether the composite glass measuring electrode is damaged and whether the measurement is invalid. In your application, to prevent common failures of the electrode, immerse the top of the head of the electrode in liquid from start to finish.

Wash the nozzle to ensure that the pH meter remains clean at all times during normal measurements. Inspection, flush testing can be carried out during commissioning.

Check the credibility of the intermediate connection between the camera mounting support frame and the immersion maintenance pipe, and check whether there is any water leakage, so that it is not possible to detect the liquid entering the maintenance pipe according to the level or electrode support frame, and then endanger all normal applications of the instrument and equipment.

Calibration: The pH meter must be calibrated at two points to determine the measurement slope before it is officially put into operation. This shows that these two standard low-speed battery charging solutions must be available before calibration, and ensures the accuracy of the calibration.

What are the precautions for the installation and maintenance of environmental protection equipment?

Exhaust gas treatment source and environmental protection.

When arranging the workshop, the possibility of installation, overhaul and dismantling of the equipment must be taken into account. The ways and means of installation, maintenance and dismantling of equipment must be considered.

Consideration must be given to how the equipment will be transported in or out of the workshop. When the equipment is transported in or out a large number of times, it is advisable to set up a gate. Generally, the width of the door of the plant is about larger than the width of the equipment that needs to pass through.

However, when the equipment is transported into the plant and rarely needs to be moved out as a whole, the installation hole can be set up, that is, the hole is reserved in the outer wall, and the equipment is transported in, and then sealed.

When the equipment passes through the floor or is installed on the second floor or higher, mounting holes can be provided in the floor slab. The mounting hole can be set up with or without a cover, if there is no cover, a detachable railing should be set around the hole. Generally, the equipment that is relatively fixed can also be equipped with an installation hole on the outer wall of the floor, and the equipment can be transported through the installation hole on the outdoor hanging.

There should be a certain area and space in the plant for equipment maintenance and disassembly, the centralized arrangement of similar equipment can be uniformly set aside for maintenance sites, the manholes of tower and vertical equipment should be empty or maintenance channels, and try to be arranged in the same direction, and the tubular heat exchanger should be set aside at the detachable end in order to extract the pipe for maintenance, especially should prevent the manhole, instrument nozzle and other nozzles from touching the beam.

When the number of equipment in the workshop is large and the weight is large, it is necessary to consider setting up the lifting and transportation height of the lifting and transportation equipment for disassembly and maintenance, which should be greater than the highest equipment height on the transportation line.

Fourth, meet the requirements of the building.

All very bulky equipment, or equipment that can produce great vibration during operation, such as compressors, centrifuges, large general machines, crushers, etc., should be arranged at the bottom of the plant as much as possible, and the weight of the equipment foundation should not be less than 3 times the weight of the equipment to reduce the load and vibration of the plant. The party must be laid out in.

In the second and third floors, it should be placed on the upper side of the beam.

For machinery with severe vibration, the operating table and foundation should not be connected with the columns and walls of the building, so as not to affect the safety of the building.

When arranging the equipment, the position of the columns, main beams and secondary beams of the building should be taken into account, and the columns and main beams must be avoided, and the main beams must be avoided if there is no perforation.

All the operating platforms in the plant must be considered in a unified way to avoid the scattered repetition of the platform pillars, save the area occupied by the structure in the plant, and achieve a more reasonable organization of operations and traffic routes.

The entrances and exits of the plant, traffic roads, and stairs should be carefully arranged. Generally, the width of the door of the plant is larger than the width of the fully loaded equipment.
