Description

Technical Field

[0001] This utility model relates to a reciprocating compressor water softening station. Background Technology

[0002] The existing reciprocating compressor water softening station has problems such as unstable operating temperature and poor pump operation safety, which need to be further improved. Utility Model Content

[0003] The purpose of this invention is to provide a reciprocating compressor water softening station with stable operating temperature and good pump operation safety.

[0004] The technical solution of this utility model is:

[0005] A reciprocating compressor water softening station includes a water tank, characterized in that: the water tank is connected to two parallel main and auxiliary water pumps, one in operation and one on standby; the outlets of the main and auxiliary water pumps are respectively equipped with overflow shut-off valves, which are adjusted to meet the minimum continuous and stable flow rate of the centrifugal water pumps; the water pumps are divided into two paths, the first path leading to the cylinder through a first bypass maintenance valve, and the second path leading to a cooling device, which consists of two parallel coolers, followed by a filtration device, which consists of two parallel Y-type filters, with the filter outlet leading to the packing material; a mixing valve is connected between the rear end of the cooling device and the front end of the first bypass maintenance valve, with the outlet of the mixing valve leading to the cylinder and through the second bypass maintenance valve to the filtration device.

[0006] The filter is connected to a differential pressure gauge.

[0007] This invention employs a self-regulating temperature control valve (mixed-flow valve) to regulate temperature, automatically adjusting the temperature by varying the valve opening to achieve temperature stability during the operation of the softened water station. Overflow shut-off valves are installed at the outlets of both the main and auxiliary water pumps. By adjusting these shut-off valves, the minimum continuous and stable flow rate of the centrifugal water pumps is ensured, protecting them and allowing them to operate under safe pressure. Attached Figure Description

[0008] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0009] Figure 1 This is a structural schematic diagram of one embodiment of the present invention. Detailed Implementation

[0010] A reciprocating compressor water softening station includes a water tank 1, which is connected to two parallel main and auxiliary water pumps 2 and 3, with one pump in operation and the other on standby. Overflow shut-off valves 4 and 5 are respectively installed at the outlets of the main and auxiliary pumps, and the minimum continuous stable flow rate of the centrifugal pumps is met by adjusting the shut-off valves. The pumps are split into two paths: the first path 6 leads to the cylinder via a first bypass maintenance valve 7, and the second path 8 is connected to a cooling device 9, which consists of two parallel coolers. A filter device 10, consisting of two parallel Y-type filters, is connected to the filter device, which is equipped with a differential pressure gauge 11. The filter device outlet leads to the packing material. A mixing valve 12 is connected between the rear end of the cooling device and the front end of the first bypass maintenance valve, with the mixing valve outlet leading to the cylinder and through a second bypass maintenance valve 13 to the filter device.

[0011] Temperature is regulated by a mixing valve. The softening water station uses a self-regulating temperature control valve to control the water supply temperature. The regulating valve will automatically adjust according to the change of its own opening degree, so that the softening water station can always maintain a stable temperature during operation, which improves the safety and stability of the equipment.

[0012] The main and auxiliary water pump outlets are each equipped with an overflow shut-off valve. By adjusting the shut-off valve, the minimum continuous and stable flow rate of the centrifugal water pump can be met, which can protect the centrifugal water pump to operate under safe pressure.
