1. The Operation of the Diaphragm Pressure Tank

1. First fill the tank with water and open the bleed valve. Filling pressure should be controlled at ≤ 1Kgf / cm2, when the water chamber when the air discharge to stop filling water, and close the release valve).
2. Adjust the pointer of the electrical contact gauge to the required maximum pressure and minimum pressure position. If the system is equipped with a pressurized pump, two pressure gauges should be set. Pressure gauge
3. Used to control the fire pump, the pointer to the minimum pressure position; table
4. Used to control the charge pump, the pointer to the highest pressure position, the next pointer to the pressure pump to start the pressure position. (3) open the inflatable valve, fill the tank with nitrogen, charge to the pressure gauge
5. When the maximum pressure (P2), the inflation is completed, close the inflatable valve. At this point, the inflatable phase is completed.
6. When the electrical contact pressure gauge line is completed correctly, slowly open the drain valve, so that the pressure inside the tank slowly down to the pressure gauge (Ⅱ) on the pointer and the next pointer coincide, the fill pump should start immediately, and then Manual control to stop the pressurized pump pressure transport operation.
7. In the case where the drain valve remains open, the tank pressure continues to drop to the pressure gauge
8. When the pointer is the minimum pressure (P1), the fire pump should start immediately, then close the drain valve and manually control the fire pump to stop running. The pump control switch to the automatic control position.
9. Start the pressurized pump, so that the pressure inside the tank to its start pressure, the pump is put into self-control operation. At this point the full charge debugging work is completed.


2. The Causes of the Diaphragm Air Pressure Capsule Damage

Diaphragm type pressure tank is made of steel shell, rubber diaphragm composed of energy storage devices. The rubber diaphragm completely separates the water chamber and the air chamber. When the outside pressure water is filled into the liner of the diaphragm type air tank, the air sealed in the tank is compressed and the volume of the gas is compressed and the pressure is increased. Energy, compressed gas expansion can be rubber within the diaphragm pressure out of the tank.

We may sometimes encounter diaphragm-type pressure tank instability situation, usually, the problem is likely to be because the tank airbag is damaged, need to replace the new airbag.

The main reason for the damage of the diaphragm is the problem of the air pressure in the diaphragm. Some new pressure tank to the site site, no one care, on the random storage, may cause the inflatable mouth was deliberately unscrewed. Also in the installation process, there is no intention to drain the gas. And some of the original quality of the airbag was poor, the tank wall weld on the leak, and so installed, the pump a dozen water pressure, the gas gave the basic squeeze. At this time the jar formed a water reservoir, did not play the role of regulation.

Reveal a replacement diaphragm tips: for good diaphragms, be sure to tighten the upper and lower bolts, according to the diaphragm pressure tank pressure and the pressure of the pump to choose a balance point value. And then inflated, after the replacement of air pressure tank air bag with soap and water in the bolt mouth and weld repeatedly smear, check to see if it leaks.

3. Selection Recommendations for Diaphragm Pressure Tank, Fire Booster Regulator Equipment

1. The diaphragm pressure tank fire boost pressure regulator system is better than the home type. On the home with a booster pump head low, the choice of air pressure tank inflatable pressure is small, large volume of regulated water, will reduce the construction costs and booster pump operating costs. But on the home-style isolation, noise reduction problems.
2. Although the total volume of the diaphragm can be smaller, but increased the booster pump power consumption, booster pump efficiency will be reduced.
3. With pressurized and pressurized equipment, fire water supply system, the fire process is actually by the high water tank, boost regulator equipment, fire pump common burden. In the event of a fire, the boost regulator system will alarm quickly and start the fire pump. So that the role of the high water tank is only to meet the pressurized water pump on the water tank of the water, and lost the temporary high pressure fire water supply system in the role of high water tank. Its volume can be reduced worth exploring.
4. Calculate the value of the absolute value of pressure, equipment selection is the use of gauge pressure, should pay attention to conversion.
5. Architectural design for the convenience of overhaul Diaphragm pressure tank pressurized pressure regulator equipment, often set two high water tank, the design should take measures to ensure that the fire boost regulator equipment can always work properly. If the high water tank for the fire, life sharing, pay attention to the booster pump suction pipe should be located below the fire water level.
6. In the design of high-rise building fire, the static pressure of the fire protection system should take into account the head of the regulator pump. If the height of the building (between the basement and the high water tank) plus the head of the regulator pump exceeds /% m, the fire system partition Water supply.
7. Diaphragm type pressure tank fire booster regulator can be used as non-self-absorption with a bottom valve fire water pump water supply device, the regulator device outlet should be connected to the fire pump outlet to check the pipe between the pipe, so that To ensure that the fire pump at any time to start.

4. Our Advantages

1 Double-sided welding for all the connecting pipes
2 All the connecting pipes are sealed by plastic parts
3 Section design for the air inlet
4 Sewage valve with elbow design
5 Longitudinal seam, ring seam welding, double - sided submerged arc welding
6 Surface treatment: sandblasting , primer (2 times), finish

5. Description

Our diaphragm pressure tank maximum working pressure were 0.6mpa, 1.0mpa, 1.6 mpa. Fire storage capacity of more than 150L, 300L, 450L. The volume of regulated water is greater than 50L. For the fire hydrant system, the water gun per share flow of 2.5L / S, 5L / S, enrich the water column length of 7M, 10M, 13M. For automatic sprinkler system, each nozzle flow is 1.0L / s, nozzle pressure is 0.1MPA. The device can make the fire water supply pipe system the most unfavorable point to always maintain the fire pressure, and the use of air pressure tank always stored 30 seconds of fire water. The equipment uses the operating pressure set by the pressure water tank to control the pump operating conditions, to achieve the function of boost regulator.
