DETAILED DESCRIPTION

[0012] The utility model will be specifically explained in connection with the drawings and specific implementation.

[0013] The utility model provides a kind of double-loop gas pump water supply system with water shortage alarm function, as shown in Figure 1 It is a structure schematic drawing of the utility model discloses a kind of double-loop gas pump water supply system with water shortage alarm function.

[0014] The water outlet of cooling water tower 4 is connected to high-level water tank 5, and high-level water tank 5 is connected to the cooling water inlet of gas pump 7; the cooling water outlet of gas pump 7 is returned to the cooling water pool.

[0015] Wherein, circulating pool 1 is used to supply water to cooling water tower 4 through main pipe or standby pipe; high-level water tank 5 is used to collect cooling water and output to the cooling system of gas pump 7; gas pump 7 is used to return the used cooling water to the circulating pool. Through double-loop water supply system, it can avoid the water supply not in time and lead to the gas pump water shortage operation, and provide the guarantee for the safe operation of gas pump.

[0016] In some embodiments, a liquid level sensor 6 is arranged on the high water tank 5, and the liquid level sensor 6 is communicatively connected to an alarm. The water level of the high water tank is monitored, a liquid level sensor is installed in the high water tank, an alarm is installed in the duty room, the alarm is controlled by the liquid level sensor, when the liquid level sensor is away from the water surface, the alarm is powered on to alarm, and the height of the sensor can be adjusted as required to control the minimum water level. If the liquid level sensor 6 detects that the water level in the high water tank 5 is lower than the monitoring value, an alarm signal is sent, and water needs to be supplemented in the high water tank 6 in time.

[0017] In some embodiments, the liquid level sensor 6 is at least two, one is arranged at the second low water level, and the other is arranged at the minimum water level. When the water level of the water tank is lower than the second low water level, the alarm will alarm; when the water level of the water tank is lower than the minimum water level, the alarm will alarm again. The two-stage alarm gives the post worker sufficient preparation time to supplement water, and ensures the normal operation of the water supply system of the gas pump.

[0018] The use method of the double-circuit gas pump water supply system with the water shortage alarm function is as follows:

[0019] Usually, the water in the circulating water pool 1 is sent into the cooling water tower 4 through the centrifugal pump 2.

[0020] If the centrifugal pump fails, power supply fails, or the pipeline is frozen in winter, etc., the submersible pump 3 in the standby pipeline is started to continue to supply water to the cooling water tower 4.

[0021] The cooling water tower 4 supplies water to the cooling system of the gas pump 7 through the high-temperature water tank 5.

[0022] The gas pump 7 outputs the used cooling water back to the circulating water pool for recycling.

[0023] If the alarm alarms, the post worker will supplement water to the high water tank in time, so as to avoid that the gas pump runs out of water due to the delay of water supplement, and to provide protection for the safe operation of the gas pump.
