Abstract
The utility model relates to an automatic protection device of safe work of a fracturing pump, which comprises a pressure sensor and a pressure controller. The automatic protection device is characterized in that a braking device is connected between a generator and a pump through a transmission box output flange, a mechanical safety valve and a pressure sensor are mounted on a fracturing pump discharge manifold through a triplet, and the pressure sensor and a pressure control device are electrically connected, the pressure control device is respectively and electrically connected with the generator and the braking device. When a fracturing pump works, a control device is used to regulate to lead the fracturing pump to work in a preset pressure range, discharge pressure exceeds a set value, the mechanical safety valve is automatically opened to decompress, thereby effectively preventing pressure from continuously ascending, when the pressure control device is out of control, the braking device is started to lead the fracturing pump to stop working and lead the generator to return an idling state. The automatic protection device solves the problems that when the generator is in idling, the fracturing pump continuously works because of the inertia function, fracturing fluid is continuously injected underground to cause pressure to continuously increase and endanger the security of work.
Description
Technical field:
The utility model relates to the fracturing pump automatic safe protective device in the fracturing unit.
Background technique:
The pressure break pump truck is the key equipment in the pressing crack construction operation, fracturing pump is the core component on the car, the glue connection liquid that under the condition of high voltage of 70MPa-140MPa the pressure break fracturing blender truck mixed need be injected the oil gas well after by the supercharging of pressure break pump truck during operation and press off oil reservoir, play the effect that increases oil, fracturing work plays a very important role in oil, gas field volume increase stable yields.The working pressure that presses off oil reservoir produces bigger variation because of the difference on stratum; especially in " broken pressure stage "; need could press off the stratum than higher working pressure; when the rapid rising of working pressure and ultimate pressure value that surpass to set; can cause fracturing pump that serious security incident takes place; therefore on the pressure break pump truck, be provided with safety stop gear.Existing safety installations is that a pressure transducer is housed on the exhaust manifold of fracturing pump, detect the fracturing pump head pressure and form pressure signal with it, pressure signal is passed to controller by cable, controller is by judging whether that relatively need provide control signal makes motor get back to idling, when working pressure surpasses setup pressure value, controller provides control signal makes the fracturing unit truck motor get back to idling conditions, stop operation, then by resetting pressure limit value or taking other measure operation again again.Mainly there is the deficiency of two aspects in this safety control: 1, motor receive stopping signal that controller sends progressively return idling during this period of time in, fracturing pump is because action of inertia is still working on, and the continuation that fracturing fluid can continue to inject shaft bottom and build-up of pressure raises and jeopardizes job safety; 2, in the equipment test process, experimental pressure can reach the peak of equipment, smaller or have under the situation of reducing at fracturing pump exhaust manifold diameter, this moment the variation in pressure electrical signal that sends of the controller pace of change of pressure that seriously lags behind, working pressure can rise and surpass the pressure-bearing limit of equipment moment, for safe construction hides some dangers for.
Summary of the invention:
The utility model is to provide a cover novel fracturing pump safety work automatic safety device, makes shutdown, the pressure release in time in the operation process in executing of pressure break pump truck, fracturing pump and operator's safety in the assurance pressing crack construction operation process.
Realize the fracturing pump safety work automatic safety device of above-mentioned purpose; comprise pressure transducer, pressure controller; it is characterized in that: between motor and pump, connect braking device by the transmission case output flange; on the fracturing pump exhaust manifold, mechanical safety valve and pressure transducer are installed by threeway; pressure transducer and pressure control device electrically connect, and pressure control device electrically connects with motor and braking device respectively.2 standard unions of mechanical safety valve band are buckled, and an end is connected with manifold, and the other end is installed emptying pipe; Pressure control device is installed in the fracturing unit truck control box, includes A/D converter, PLC main controller, RS232/485 module, computer, D/A converter.Braking device mainly comprises brake disc, friction plate and brake cylinder, brake disc rotates with the transmission case output flange, friction plate is controlled by brake cylinder, and by the opening and shutting off of electromagnetic valve brake cylinder source of the gas, solenoid valve and pressure control device electrically connect.
When pump work, the pressure signal of pressure transducer collection is transferred to pressure control device, the pressure signal that pressure control device receives is changed, is compared, when on-the-spot pressure is higher than setting pressure during force value, pressure control device provides two path control signal, one the tunnel transfers to motor, makes it get back to idling immediately; Another road transfers to the brake solenoid valve and starts braking device, cuts off motor and gets back to the power source that causes because of inertia in the idling process, and fracturing pump is quit work immediately; If the situation that control pressurer system lost efficacy, be installed in the mechanical safety valve releasing pressure automatically when fracturing pump high pressure occurs and is higher than the exhaust manifold setup pressure value on the pump, solve the problem of pressure break pump truck safety work by machinery and automatically controlled mode.
The utility model compared with prior art has following beneficial effect:
1, by braking device being set between motor and fracturing pump and controlling motor and braking device respectively by control gear; solved when fracturing pump occurs exceeding setup pressure value; lag behind pressure signal and the problem that can not shut down rapidly in the engine idle process that causes to the electrical signal that control gear sends, make the safety of fracturing pump be in effectively Guaranteed.
2, the exhaust manifold at pump increases mechanical safety valve; can prevent under pressure control device situation suddenly out of control as backup safety device; mechanical safety valve also can be protected pressure break pump truck safety by releasing pressure automatically, has thoroughly eliminated the potential safety hazard that present fracturing unit truck safety control exists.
