Background technique
During the operation of pressure break pump truck, there is pressure high, the working condition that discharge capacity is large, require during operation that the parts such as the gear reduction box to fracturing pump, bearing, crosshead and pull bar carry out lubrication and cooling, and owing to there is attrition in transmission, the iron filings existed in lubricant oil and copper scale can affect the lubricating pipe of fracturing pump self, even can block the injection system of fracturing pump, cause lubricant oil cannot normal supply, if lubrication system goes wrong, fracturing pump internal moving parts will be caused to occur burning seize phenomenon to death.
The fracturing pump lubrication system of existing massive hydraulic fracturing pump group equipment adopts the additional safety valve of gear pump to control lubrication pressure usually, Stress control requirement accurately cannot be reached, and be generally arranged on the filler opening of fracturing pump due to safety valve, effectively can not form the protection to fracturing pump filler opening front end component (as radiator); In addition, lubrication oil filtration is generally adopt fuel tank built-in filter, is difficult to reach the turbidity test requirement of fracturing pump to lubricant oil.
Model utility content
The purpose of this utility model is to provide the fracturing pump lubricant oil road structure of a kind of triple burden protection, solves in prior art and adopts the additional safety valve of gear pump to control lubrication pressure, cannot reach Stress control requirement accurately; And adopt fuel tank built-in filter, be difficult to reach the problem of fracturing pump to cleanliness of lubricating oil requirement.
The technological scheme that the utility model adopts is, a fracturing pump lubricant oil road structure for triple burden protection, comprise vane pump, vane pump outlet end is divided into two-way, relief valve one of leading up to takes back fuel tank, and filter two of separately leading up to is communicated with thermostat valve entry end;
Thermostat valve outlet end is divided into two-way, and a road is directly communicated with the filler opening of fracturing pump, and another road is communicated with the filler opening of fracturing pump by radiator and one-way valve successively;
Be provided with safety valve before the filler opening of radiator, be provided with relief valve two and pressure transducer before the filler opening of fracturing pump, safety valve is all communicated with fuel tank with relief valve two outlet end.
The fracturing pump lubricant oil road structure of triple burden protection of the present utility model, is further characterized in that:
The entrance point of vane pump is provided with filter one, and filter one is positioned under the liquid level of fuel tank.
The beneficial effects of the utility model are, accurately can control the pressure of whole oil circuit all parts, all parts on protection oil circuit, and safety valve adopts tubular type to connect, and installation and maintenance are simple, and field adjustable is convenient.Adopt secondary oil filtrating, all mounting filter on fuel tank and pressure oil pipeline, ensures the turbidity test of fluid, and detects the pressure size of fracturing pump filler opening in real time, ensure pressure and the flow of lubricant oil.This oil circuit simplicity of design, Operation and Maintenance is simple, and safety reliability is high, meets the requirement of fracturing pump to the turbidity test of lubricant oil, flow and pressure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1. vane pump, 2. filter two, 3. thermostat valve, 4. relief valve one, 5. safety valve, 6. one-way valve, 7. relief valve two, 8. pressure transducer, 9. fracturing pump, 10. fuel tank, 11. radiators, 12. filters one.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
With reference to Fig. 1, structure of the present utility model is, comprise vane pump 1, the entrance point of vane pump 1 is provided with filter 1 and is positioned under the liquid level of fuel tank 10, vane pump 1 outlet end is divided into two-way, relief valve 1 of leading up to takes back fuel tank 10, and filter 22 of separately leading up to is communicated with thermostat valve 3 entry end; Thermostat valve 3 outlet end is divided into two-way, one tunnel is directly communicated with the filler opening of fracturing pump 9, another road is communicated with the filler opening of one-way valve 6 with fracturing pump 9 by radiator 11 successively, safety valve 5 is installed before the filler opening of radiator 11, be provided with relief valve 27 and pressure transducer 8 before the filler opening of fracturing pump 9, safety valve 5 is all communicated with fuel tank 10 with relief valve 27 outlet end.
Working principle of the present utility model is,
First, the lubricant oil that vane pump 1 oil outlet produces arrives the filler opening of thermostat valve 3 through filter 22, and when overpressure, fluid is through relief valve 1 off-load; Then, thermostat valve 3 carries out fluid passage selection according to the temperature of lubricant oil, and when temperature is lower than 65 DEG C, the filler opening that lubricant oil directly enters fracturing pump 9 lubricates pressure pump 9; When temperature is higher than 65 DEG C, lubricant oil enters the filler opening of fracturing pump 9 successively through radiator 11 and one-way valve 6, at the filler opening of radiator 11, safety valve 5 is installed, restriction enters the lubrication pressure of radiator 11, at the filler opening of fracturing pump 9, pressure transducer 8 and relief valve 27 are installed, ensure the pressure stability entering fracturing pump 9 lubricant oil;
In oil circuit, adopt secondary oil filtrating, fuel tank and pressure oil pipeline are separately installed with a filter (filter 1 and filter 2 2), ensure the turbidity test of fluid;
3 pressure protection valves (i.e. relief valve 1, safety valve 5 and relief valve 2 7) are provided with in oil circuit; wherein the outlet pressure of relief valve one 4 pairs of vane pumps 1 controls; safety valve 5 pairs of radiators 11 carry out overvoltage protection, and relief valve 27 accurately can control the lubrication pressure entering fracturing pump 9.Relief valve 1, safety valve 5 and relief valve 27 three cooperating, can control the pressure of whole oil circuit, maintains the flow needed for lubrication system and pressure.Due to the back pressure effect of one-way valve 6, the lubricant oil entering radiator 11 fully can be dispelled the heat, ensure good radiating effect.Safety valve 5 and relief valve 27 adopt tubular type to be connected, easy for installation.Pressure transducer 8 detects input pressure in real time, and owing to being provided with 3 pressure protection valves, can realize triple burden protection, reliability is high, and site examining and repairing is convenient.
Oil channel structures of the present utility model, arrange simple, reliability is high, convenient operating maintenance, meets the requirement of fracturing pump to the turbidity test of lubricant oil, flow and pressure completely.
