Abstract

The present disclosure provides a fracturing equipment. The fracturing equipment includes: a plunger pump, a main motor and a noise reduction device. The plunger pump is used for pressurizing liquid. The main motor is connected to the plunger pump by transmission for providing driving force to the plunger pump. The noise reduction device is constructed as a cabin structure and covers outside the main motor and isolates the main motor from the plunger pump. With the fracturing equipment according to the present disclosure, the fracturing equipment is driven by the main motor with relatively low noise during operation. The noise reduction device isolates the main motor from the outside, which can effectively reduce the noise intensity transmitted to the outside during operation, thereby achieve the effect of noise reduction. In addition, the plunger pump is isolated from the main motor by the noise reduction device, thus realizing isolation of high-pressure dangerous areas and ensuring safe operation.

First claim

We claim:

1. A fracturing equipment, comprising:
a plunger pump for pressurizing liquid;
a main motor connected to the plunger pump by a transmission and configured to provide a driving force to the plunger pump;
a noise reduction device configured as a cabin structure, wherein the noise reduction device covers the main motor and isolates the main motor from the plunger pump;
an oil tank containing lubricating oil; and
a lubrication driving device for driving lubricating oil from the oil tank to the plunger pump to lubricate the plunger pump, wherein the lubrication driving device includes a lubrication pump and a lubrication motor, and wherein the lubrication pump or the lubrication motor is arranged inside the noise reduction device.

2. The fracturing equipment according to claim 1 , wherein the fracturing equipment further comprises:
a primary exhaust silencer connected with an exhaust port of a cooling fan configured to cool the main motor, wherein the exhaust port of the cooling fan is connected to the primary exhaust silencer via a soft connection, and wherein a flow area of an airflow passage in the soft connection gradually increases along an airflow direction.

3. The fracturing equipment according to claim 1 , wherein the fracturing equipment further comprises:
a cooler having a fan and configured to dissipate heat from the lubricating oil by air blast cooling; and
a cooler motor connected to the cooler and configured to provide the driving force to the cooler;
wherein, the cooler and the cooler motor are arranged inside the noise reduction device.

4. The fracturing equipment according to claim 3 , wherein the cooler is arranged above the main motor, and a top of the noise reduction device is provided with a cooler window at a position corresponding to the cooler.

5. The fracturing equipment according to claim 3 , wherein the cooler is configured as a cuboid and comprises at least two fans arranged along a length of the cuboid.

6. The fracturing equipment according to claim 3 , wherein at least one side of the noise reduction device is provided with at least one air inlet, and an air inlet silencer is provided at the at least one air inlet.

7. The fracturing equipment according to claim 1 , wherein the main motor comprises a cooling fan configured to cool the main motor through air suction cooling.

8. The fracturing equipment according to claim 7 , wherein the fracturing equipment comprises a primary exhaust silencer arranged inside the noise reduction device and connected with an exhaust port of the cooling fan.

9. The fracturing equipment according to claim 8 , wherein the exhaust port of the cooling fan is connected to the primary exhaust silencer via a soft connection.

10. The fracturing equipment according to claim 8 , wherein the fracturing equipment further comprises a secondary exhaust silencer which is provided on the noise reduction device and corresponds to an exhaust port of the primary exhaust silencer.

11. The fracturing equipment according to claim 1 , wherein an outer surface of the main motor is wrapped with a noise reduction material.

12. The fracturing equipment according to claim 1 , wherein a wall of the noise reduction device is constructed as a sandwich structure filled with a noise reduction material.

13. A fracturing equipment, comprising:
a plunger pump for pressurizing liquid;
a main motor connected to the plunger pump by a transmission and configured to provide a driving force to the plunger pump;
a noise reduction device configured as a cabin structure, wherein the noise reduction device covers the main motor and isolates the main motor from the plunger pump;
a cooling fan configured to cool the main motor; and
a primary exhaust silencer arranged inside the noise reduction device and connected with an exhaust port of the cooling fan, wherein the exhaust port of the cooling fan is connected to the primary exhaust silencer via a soft connection, and wherein a flow area of an airflow passage in the soft connection gradually increases along an airflow direction.

14. A fracturing equipment, comprising:
a plunger pump for pressurizing liquid;
a main motor connected to the plunger pump by a transmission and configured to provide a driving force to the plunger pump;
a noise reduction device configured as a cabin, wherein the noise reduction device covers the main motor and isolates the main motor from the plunger pump;
an oil tank containing lubricating oil;
a lubrication driving device for driving lubricating oil from the oil tank to the plunger pump to lubricate the plunger pump, wherein the lubrication driving device includes a lubrication pump and a lubrication motor;
a cooler having a fan and configured to dissipate heat from the lubricating oil; and
a cooler motor connected to the cooler and configured to provide the driving force to the cooler, wherein the cabin covers the cooler and the cooler motor.

15. The fracturing equipment according to claim 14 , wherein the cabin covers the lubrication pump or the lubrication motor.
