Abstract
The utility model relates to a closed static drive system oil supply device of a sand mixing vehicle, which belongs to the field of driving system oil supply devices. The utility model is composed of a hydraulic oil tank, a coarse filter, a hydraulic hose, a quantitative hydraulic pump, a safety valve, a fine filter, an oil collecting pipe, a one-way valve and a two-way volume-adjustable hydraulic pump. The closed static drive system oil supply device is characterized in that hydraulic oil is filtered through the coarse filter and is output through the quantitative hydraulic pump, and then, the hydraulic oil enters a liquid filling port of the two-way volume-adjustable hydraulic pump through the one-way valve; thus, the disadvantages of the two-way volume-adjustable hydraulic pump that the hydraulic oil leakage is increased and the supplies oil provided by an oil supply pump is insufficient due to the abrasion of a flow distribution disk, a swash plate, a plunger piston, etc. are made up when the two-way volume-adjustable hydraulic pump is under the condition of low rotating speed or after the two-way volume-adjustable hydraulic pump works for a period of time. The utility model solves the problems of the two-way volume-adjustable hydraulic pump of the existing closed static drive system under the condition of low rotating speed that the supplied oil flow provided by the oil supply pump is reduced, and the supplied oil flow of the system is insufficient, causing the whole mechanism to be unable to work or the damage to the hydraulic pump or the reduction of the service life for the hydraulic pump. The utility model is widely suitable to be used in a drive mechanism of a sand mixing vehicle in an oil field.
Description
Affiliated technical field:
The utility model relates to a kind of fracturing blender truck closed type static pressure transmission system recharging oil device, belongs to transmission system recharging oil device field.
Background technique:
The most of closed type static pressure transmission system that adopts of the driving mechanism of fracturing blender truck, its main device---bidirectional variable oil hydraulic pump also has slippage pump except that main pump, and main pump and slippage pump are formed one.It is to replenish main pump, motor, control valve leakage and control oily consumption that slippage pump mainly acts on.Because slippage pump is that manufacturer configures according to intermediate value, the shortcoming that so just has two aspects: one, the bidirectional variable oil hydraulic pump is under slow-speed of revolution situation, the repairing flow that slippage pump provided reduces, can there be the problem of repairing deficiency in the closed type static pressure transmission system, thereby can cause that entire mechanism can't work or damage oil hydraulic pump.Two, the bidirectional variable oil hydraulic pump is after work a period of time, because wearing and tearing such as thrust plate, swash plate and plungers, hydraulic fluid leak increases, and the repairing that slippage pump provided certainly will be not enough, and the expensive bidirectional variable hydraulic pump works life-span is shortened, and damages in advance.
Summary of the invention:
The purpose of this utility model is to provide a kind of and can makes bidirectional variable oil hydraulic pump proper functioning under slow-speed of revolution situation, can improve the closed type static pressure transmission system recharging oil device of its operating life again.
The utility model is to solve the problems referred to above by following technical solution: this closed type static pressure transmission system recharging oil device is made up of hydraulic oil container, coarse-grain filtering device, hydraulic hose I, quantitative hydraulic pump, safety valve, hydraulic hose II, fine filter, hydraulic hose III, oil collecting pipe, one-way valve, hydraulic hose IV, bidirectional variable oil hydraulic pump.It is characterized in that: the coarse-grain filtering device inlet opening is connected with hydraulic oil container by bolt, its delivery outlet is connected with the quantitative hydraulic pump inlet opening by hydraulic hose I, the quantitative hydraulic pump delivery outlet is connected with the safety valve inlet opening with bolt by flange, the discharge capacity of quantitative hydraulic pump is the 5%-10% of main pump, and the pressure of safety valve should be higher than the safety valve pressure 0.2-0.4MPa of slippage pump.The safety valve delivery outlet is connected with the fine filter inlet opening by hydraulic hose II, the fine filter delivery outlet is connected with the oil collecting pipe inlet opening by hydraulic hose III, the oil collecting pipe delivery outlet is connected with the one-way valve inlet opening by screw thread, and the one-way valve delivery outlet is connected with bidirectional variable oil hydraulic pump implementation of port by hydraulic hose IV.This recharging oil device is that hydraulic oil filters by coarse-grain filtering device, export through quantitative hydraulic pump, and enter bidirectional variable oil hydraulic pump implementation of port by one-way valve, thereby remedy the bidirectional variable oil hydraulic pump under slow-speed of revolution situation or after work a period of time, because wearing and tearing such as thrust plate, swash plate and plunger, hydraulic fluid leak increases, the repairing deficiency that slippage pump provided.
The utility model compared with prior art has following beneficial effect:
1. the bidirectional variable oil hydraulic pump the repairing quantity not sufficient can not occur under slow-speed of revolution situation, and causes that entire mechanism can't work or damage the problem of oil hydraulic pump.
2. remedy the bidirectional variable oil hydraulic pump automatically under the slow-speed of revolution situation or after work a period of time, because wearing and tearing such as thrust plate, swash plate and plungers, hydraulic fluid leak increases, the problem of the repairing deficiency that slippage pump provided.
