CEMENTING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/122952
Kind Code:
A1
Abstract:
Disclosed in the present application is a cementing apparatus. The cementing apparatus comprises a plunger pump, hydraulic transmission assemblies, a first transfer case, a gearbox and a chassis engine, wherein the hydraulic transmission assemblies are connected between the plunger pump and the first transfer case; the first transfer case is connected between the gearbox and the hydraulic transmission assemblies; the gearbox is connected between the first transfer case and the chassis engine; and the chassis engine is configured to output power, and the power outputted by the chassis engine is transmitted to the plunger pump via the gearbox, the first transfer case and the hydraulic transmission assemblies. In the cementing apparatus of the present application, the plunger pump is driven by the power outputted by the chassis engine, such that a platform engine does not need to be additionally provided on the cementing apparatus, thereby reducing the weight of the cementing apparatus, and also making the output power of the cementing apparatus more suitable for working conditions with low pressure and small amounts of displacement.
