Description

Technical Field

[0001] The utility model relates to the technical field of liquid supply devices, in particular to a large-displacement intelligent digital constant-pressure and constant-displacement liquid supply device. Background Art

[0002] The air pump liquid supply system can be divided into two types according to the different pressurized materials: gas pressurization and liquid pressurization. In addition, it can also be divided into double tank type and single tank type according to the number of pressurized tanks. In the single tank type, there are constant pressure tank type and alternating type. After throttling and reducing the pressure, the high-pressure ammonia liquid enters the circulation barrel. The liquid level of the circulation barrel is controlled by the telemetry float liquid level controller. At this time, the working states of tanks A and B are different. The solenoid valve on the pressure equalizing pipe of tank A is opened to connect it with the circulation barrel, and the solenoid valve on the high-pressure air pipe is closed to cut off the high-pressure gas source. The solenoid valve of the pressure equalizing pipe on tank B is opened to connect it with the circulation barrel, and the solenoid valve on the high-pressure air pipe is opened to send high-pressure gas into the tank. The liquid in the circulation barrel enters tank A by gravity, and the liquid level moves from the lower limit to the lower limit. When the liquid level in tank A reaches the upper limit. The liquid level in tank B is just at the lower limit, and the liquid supply process of a cycle ends. The solenoid valves on tanks A and B immediately alternate between the open and closed states, so that tank B starts to inject liquid, and tank A supplies liquid to the evaporator, and the next cycle of liquid supply begins. This system uses only one tank in the dual tank system. The filling and draining of the single tank is exactly the same as the working process of one tank in the dual tank system. During the filling process of the single tank, the liquid is supplied to the evaporator by direct expansion.

[0003] The application number is 201811205065.4, which discloses a liquid supply device, which is used to supply liquid to a user end, and the liquid supply device includes: a liquid storage tank, which is used to store liquid to be supplied, and there are multiple liquid storage tanks, and the multiple liquid storage tanks are used to be selectively connected or disconnected with the user end; a pneumatic drive system, which includes an air supply part, which is used to communicate with the liquid storage tank, so that when the air supply part provides gas to the liquid storage tank, the gas drives the liquid to be supplied in the corresponding liquid storage tank to flow to the user end; wherein the air supply part can be selectively connected or disconnected with each liquid storage tank. The liquid supply device of the present invention solves the problem that the liquid supply device in the prior art needs to stop supplying liquid for secondary liquid addition during the liquid supply process.

[0004] However, there are some shortcomings. The device can be selectively connected or disconnected with each liquid storage tank through the air supply part, which solves the problem that the liquid supply device in the prior art needs to stop supplying liquid for secondary liquid filling during the liquid supply process. However, the device does not have a protective device on the power component part, the power component is easily damaged, and the device cannot realize the intelligent digital constant pressure and constant discharge function, and has limitations.
