Description

The Hydraulic Pump power takeoff

Technical field

The utility model relates to a kind of Hydraulic Pump power takeoff, and it belongs to corollary equipment field, oil field.

Background technology

In corollary equipment field, oil field; Horsepower output is the main flow trend that the diffusing fracturing truck of the horizontal water of the employing of 2500hhp has become the fracturing truck Future Development; Because this fracturing truck power is bigger, its change speed gear box can be selected the tor-con and the change speed gear box of Twin Disc Inc. usually for use.

The hydraulic efficiency pressure system that is used for the FC Fan Control of ride cooling system on the fracturing truck; Because its variable piston pump capacity that needs is very big, cause the volume of Hydraulic Pump also very big, and the power taking mouth that the output flange of dicyclo tor-con and tor-con itself carry is too near; Cause the Hydraulic Pump of big discharge capacity can't install herein; In addition, be used for the lubricated lubricating pump of big pump power end and also be installed in power taking mouth wherein, this more makes the installing space epitonos of Hydraulic Pump.

Adopt the fracturing truck of dicyclo tor-con and change speed gear box at present both at home and abroad; Its power taking that is used for the hydraulic efficiency pressure system of FC Fan Control has two kinds of schemes: the one, and through the chassis power taking, so just cause fracturing truck must guarantee that when construction operation engine in situ is in running order; The 2nd, drive Hydraulic Pump through on the ride engine crankshaft belt pulley, installing transmission shaft additional, will take the preceding space of ride driving engine like this.Adopt the drawback of first kind of scheme to be: the power of the ride driving engine that fracturing truck adopts is 3000bhp; The fracturing pump that adopts is that maximal input is the Five-cylinder piston pump of 2800bhp; The power that is used for the hydraulic efficiency pressure system of FC Fan Control is about 100bhp; The power of engine in situ is generally 450bhp～500bhp, if adopt engine in situ drive fan controlled hydraulic system, then can make the engine power on ride and chassis can not get effectively utilizing and the waste resource; Adopt the drawback of second kind of scheme to be: the space before the driving engine is taken by Hydraulic Pump, can influence rational deployment and effective utilization in space between the car load parts.

The utility model content

The utility model can cause the wasting of resources to available technology adopting engine in situ drive fan controlled hydraulic system, installs transmission shaft additional and drives Hydraulic Pump and can make and car load parts layout and the relatively poor deficiency of space utilization a kind of Hydraulic Pump power takeoff is provided.

The technical scheme that the utility model solves the problems of the technologies described above is following:

A kind of Hydraulic Pump power takeoff comprises tor-con, and said tor-con is provided with power taking armatine, power taking mouth second and power taking mouth third; Said power taking armatine place is equipped with big pump power end lubricating pump, and said power taking mouth second place is equipped with dump pump and all has Variable plunger pump first, the Variable plunger pump second that tail drives, and said power taking mouth third place is equipped with the tor-con oil pump.

Compared with prior art, the beneficial effect of the utility model is: thus the Occupation coefficient that has reduced engine in situ has reduced its wearing and tearing, and saved fuel; Saved the space before the driving engine, for the rational deployment of car load and the rational Application in space have been created condition; Make full use of the power taking mouth that the dicyclo tor-con carries, need on the chassis, not increase extra power takeoff and transmission shaft, thereby reduce equipment cost.

On the basis of technique scheme, the utility model can also be done following improvement.

Further, the front end of said Variable plunger pump second is installed on the Variable plunger pump first, and the rear end is equipped with dump pump; Said Variable plunger pump first is installed on the power taking mouth second.

Further, said Variable plunger pump first, Variable plunger pump second and dump pump single-piece installation site can exchange with the installation site of tor-con oil pump.

Adopt the beneficial effect of above-mentioned further scheme to be: for being connected in series, to make layout more reasonable between Variable plunger pump first, Variable plunger pump second and the dump pump, saved the space greatly.
