Features
• The original Mercedes Benz chassis imported from Germany ensures the
excellent mobility of the unit in various working conditions; proper
power matching, reasonable load distribution, compact structure,
humanized design and manufacturing bring the high performance. The
maximum displacement of the unit is up to 20 m
3/min (130 bpm).
•
Power system: compared with competitors' two-engine layout, this unit
has only one horizontal engine, which provides large space for the
maintenance of engine. The filter element and oil dipstick can be
observed and maintained conveniently.
• Manifold system:(1)By
switching butterfly valves, either side can be used as suction or
discharge and temporary acidizing bypass can be achieved, which meet
different operation requirements and makes the arrangement at well site
more flexible;(2)Optimize the manifold through 3D design and fluid
analysis to have compact structure and reasonable layout so as to
guarantee smooth flow and enough pressure of the discharged
fluids.(3)High-performance flowmeter is used to meter the suction and
discharge flowrate at different displacement operations accurately. The
flowmeter can be chosen from electromagnetic flowmeter and turbine
flowmeter as needed.
• Mixing system: (1)The tub adopts advanced
vertical tub-within-a-tub design: the turbine blades and tank wall fin
are optimized after fluid analysis to ensure slurry of high sand ratio
can be completely and continually mixed; the design uses high surface
area to ensure even mixing at small sand ratio. (2)Adopt guide wave
radar level meter to eliminate the influence from bubbles and swirling
flow to liquid level and achieve high-precision liquid level control;(3)
Proved through site operations, the unit can meet the requirements of
large displacement operations with not only conventional base fluid but
also slickwater.
• Chemical additive system: (1) Equipped with four
liquid additive systems of different displacements. The chemical
additive pumps are imported rotor pumps which feature stable and
reliable performance and high conveying precision to convey chemical
additives of different viscosity;(2)Two stainless steel liquid additive
tanks (300L each) are installed behind operation platform, which are
connected at the bottom by pipelines, so the liquid additive pumps can
suck in liquids from either of them;(3)Liquid additives can be added
into sand blending tub or the manifold between sand blending tub and
discharge centrifugal pump by switching ball valves; The control of
function ball valves are integrated on the operation platform, which is
easy, convenient and reliable; EMD encoder is adopted to realize
accurate measurement of the flowrate of liquid additive pumps;(4)
Residual liquid purging device is equipped to purge the residual liquid
in the manifolds after operation.(5)Two high-precision dry powder
feeders meet the adding requirements of different displacements.
•
Sand conveying device:(1)the high-precision augers designed with
independent lifting and splitting function meet requirements of
different site arrangements and operation.(2)The auger adopts new
technology to improve conveying precision and meet the operation
requirements of starting with load but without getting stuck.
•
Hydraulic system:(1)All of the hydraulic components are imported parts
with stable and reliable performance as well as long service life.(2)
The suction, discharge, sand conveying system are all closed-loop
hydraulic systems, which have higher efficiency.(3) The liquid additive
system, dry additive system and blending system adopt load sensitive
system which achieves stepless speed regulation of each parts by
proportional control and is good for energy saving and environment
protection;(4)Oil temperature is automatically controlled by oil cooler
and there is no need of manual control.
• Electric control system:
(1) Totally self-developed and patented control system is able to meet
personalized demands of customers.(2) High-level automation realizes the
automatic control of liquid level, adding chemical additive, sand
concentration and discharge. (3) Multiple redundancy guarantees various
control styles including manual, automatic and screen control.(4) The
clear and simple HMI design with the idea of "what you see is what you
get design” realizes humanized operation as the switch status,
manual/automatic status are displayed on the screen. (5) Program is
designed to set up to 100 operation stages, which meets the requirements
of step and ramp sand adding. (6)Excellent compatibility realizes
online data transfer with data vans of other brands. (7) Intelligent
maintenance system can be provided according to customer requirements
and it can achieve engine maintenance reminding and automatic trouble
diagnosis; (8)Adopt imported flowmeter, level meter and HMI with high
performance and reliability.
• Others:(1) Equipped with spare tire
hoisting mechanism to lift the spare tire through one button;(2)Equipped
with two large tool boxes installed on the driver side and passenger
side respectively for storing tools and other materials
conveniently;(3)Comfortable control cabin with air-conditioner; (4) Fuel
tank of 1000L provides sufficient fuel for both deck and chassis
engines.
