Abstract

The invention discloses an electric drive well cementing cement truck, which comprises a car chassis, an inspection platform is fixedly connected to the girder of the car chassis, a mud mixing tank is fixedly connected to the repair platform, and a mixer and agitator are arranged on the upper part of the mud mixing tank. The mixer is connected to the water channel and the ash channel through pipelines; there are two outlets at the bottom of the mixing tank, one outlet is connected to the first sand pump and the circulating mud manifold in turn, and the outlet of the circulating mud manifold is respectively connected to the density meter and the second One end of the secondary mixing manifold, the other end of the secondary mixing manifold is connected to the slurry inlet of the mixer; the other outlet of the mixing tank is connected to the second sand pump, booster manifold, and plunger pump in sequence , Discharge manifold, and the discharge manifold is also connected with a pressure relief manifold. The beneficial effects of the present invention are: convenient installation and connection of equipment; high power density; high working efficiency of the whole vehicle; clean energy and zero discharge.

Description

technical field [0001] The invention belongs to the technical field of cement trucks for well cementing, and in particular relates to an electrically driven cement truck for well cementing. Background technique [0002] With the continuous development of shale gas resources in my country, the frequency of cementing operations in ultra-deep wells and complex formations is increasing. High pressure, large displacement, and long-term uninterrupted cementing operations have gradually become the norm. Conventional single-machine single-pump, double-machine double-pump and even thousand-type pump cementing trucks cannot fully meet the construction requirements due to power limitations. [0003] When a conventional cement truck is in operation, the diesel engine drives the cementing plunger pump through the gearbox through the transmission shaft, and the hydraulic system of the vehicle is driven by the chassis engine. The diesel engines and gearboxes commonly used in the market are...
