Background technique
It the use of fracturing technique is one of the important technical produced in oil gas field increasing the storage during exploitation of oil-gas field, benefit
So that stratum is formed crack with high-pressure fluid, to enhance oil-gas Layer permeability, achievees the purpose that improve oil and gas production.Make in pressure break
When industry, the superiority and inferiority of corollary equipment performance directly determines the efficiency and quality of well fracturing construction.In pressure break corollary equipment, far
Journey water supply liquid supply equipment is that upstream water source is supplied to other with the key device of water liquid corollary equipment, constructs links all
It needs largely to supply water with the complete well link of liquid, especially pressure break, water consumption has all reached tens of thousands of side's meters substantially.
Currently, the domestic long-range water supply liquid supply equipment generally used only has a set of liquid-supplying system, by adjusting feed flow system
The revolving speed of motor changes the discharge capacity of pump in system.It needs additionally to connect a set of manifold system when water supply feed flow operation, to realize to not
With the water supply feed flow of equipment, often there are the following problems in use:
1, the supply arrangement big from water demand amount, when turning again to as the small equipment of other water demand amounts, due to the discharge capacity of pump
Change it is excessive, cause connection motor long-time excess load low-speed running.
2, because being only equipped with a set of liquid-supplying system, so that long-range water supply liquid supply equipment can not be two or more equipment simultaneously
Feed flow, only for a kind of equipment feed flow after the completion of, could be to another equipment feed flow.
3, it when long-range water supply liquid supply equipment works, needs additionally to connect a set of manifold system between each liquid supply equipment, lead to
Valve group different in manual switching tube remittance system is crossed, realizes and feed flow is carried out to different equipment.Artificial cost is increased, is made
The industry period is long, operating efficiency bottom.
Summary of the invention
The technical problem to be solved by the present invention is to overcome existing long-range water supply liquid supply equipment function present in background technique
Can it is single can not for two or more equipment simultaneously feed flow the problem of, and provide a kind of branch liquid supply equipment, the branch liquid supply equipment,
