[0018] To make the above - mentioned objects, features, and advantages of the present utility model more obvious and understandable, the following will make a detailed description of the specific implementation manners of the present utility model with reference to the drawings in the specification.

[0019] Refer to Figure 1-2, A double - pump skid for an evaporative condenser provided by the present utility model. This double - pump skid for an evaporative condenser includes a base frame 1. At both ends of the base frame 1, there are respectively arranged circulating pumps 2. The two circulating pumps 2 are arranged symmetrically left and right. At the inlet end of the circulating pump 2, there is an inlet pipe 3. The other end of the inlet pipe 3 is provided with an inlet control valve 4. The other end of the inlet control valve 4 is provided with an evaporative - cooler inlet connecting pipe 5. At the outlet end of the circulating pump 2, there is an outlet pipe 6. The other end of the outlet pipe 6 is provided with an outlet control valve 7. The other ends of the two outlet control valves 7 are provided with an outlet connecting pipe 8.

[0020] Specifically, the two circulating pumps 2 are arranged symmetrically left and right and share the same outlet connecting pipe 8 of the evaporative cooler. The circulating water in the evaporative - cooler water tank enters through the inlet connecting pipe 5 on one side of the double - pump skid, flows through the inlet control valve 4 of the pump and the inlet pipe 3 of the pump, and then enters the circulating pump 2. After being pressurized by the circulating pump 2, it passes through the outlet pipe 6 of the pump and the outlet control valve 7 of the pump, and flows into the upper part of the heat - exchange tube bundle in the evaporative - cooler equipment body through the outlet connecting pipe 8 of the evaporative cooler for cooling and heat - exchange; the two circulating pumps 2 are respectively located at both ends of the pump base frame 1, and are arranged symmetrically left and right along the length direction of the pump base frame 1. The outlet end of each circulating pump 2 faces the outlet connecting pipe 8, and the inlet end faces away from the outlet connecting pipe 8.

[0021] The base frame 1 is welded into a rectangle with channel steel. Bolt holes are opened on the channel steel extending from one side of the base frame 1 in the width direction, and fastening bolts are pre - installed in each bolt hole.

[0022] Specifically, the base frame 1 can be directly bolt - connected and fixed to each equipment body of the evaporative cooler.

[0023] A flange is provided between the inlet end of the circulating pump 2 and the inlet pipe 3, and a flange is provided between the outlet end of the circulating pump 2 and the outlet pipe 6.

[0024] The size and aperture of the flange are consistent with the size and aperture of the inlet end and outlet end of the circulating pump 2.

[0025] The inlet control valve 4 and the outlet control valve 7 are preferably wafer - type butterfly valves and flange - type butterfly valves.

[0026] Specifically, the structural form of the circulating pump 2 includes but is not limited to vertical centrifugal pumps; the structural forms of the inlet control valve 4 of the pump and the outlet control valve 7 of the pump include but are not limited to wafer - type butterfly valves and flange - type butterfly valves.

[0027] The two circulating pumps 2 at both ends of the outlet connecting pipe 8 are connected in parallel with each other.

[0028] Specifically, the two circulating pumps 2 are designed to be connected in parallel with each other, and either one of them can be selected as the working pump and the other as the standby pump.

[0029] During the use process, when the working pump fails, immediately close the inlet control valve 4 of the water pump and the outlet control valve 7 of the water pump at both ends of the inlet and outlet of the working pump. At the same time, open the control valves at both ends of the inlet and outlet of the standby pump, open the water path on the standby pump side, and the standby pump immediately starts to work to ensure the continuous and stable operation of the evaporative cooler equipment; in addition, bolt holes for the circulating water pump 2 are provided at corresponding positions at both ends of the water pump base frame 1. During actual installation, the circulating water pump 2 can first be bolted and fixed to the water pump base frame 1 through the bolt holes on the water pump base frame 1, and then the inlet end and the outlet end of the circulating water pump 2 are respectively bolted to the inlet pipe 3 of the water pump and the outlet pipe 6 of the water pump. Finally, the inlet connecting pipe 5 of the evaporative cooler and the outlet connecting pipe 8 of the evaporative cooler are respectively installed. Since the bolted connection method that can be disassembled later is adopted, when the working pump fails and the standby pump starts to work, the faulty working pump can also be disassembled and replaced, which is convenient for later maintenance and repair.

[0030] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
