Description
Technical field
The utility model relates to a kind of safety protection device of oil drilling corollary equipment pump group, specifically is a kind of slurry pump superpressure open flow arresting gear.
Background technique
The pump group is the important component part of oil-well rig, and the pump group mainly is power with the diesel engine, drives slurry pump drilling fluid is input in drilling tool, drill bit and the well with certain pressure and flow, realizes the circulation of drilling fluid of whole drillng operation.When the drilling liquid pressure superpressure threatened to slurry pump, the safety valve open flow pressure release of installing on it was played the safety protection effect to equipment.In the known technology; the pump group only has the safety valve of installing on the slurry pump to play effect to the pressure release of mud circulating system open flow; but do not control the device of diesel engine autostop simultaneously; still need the manual operation diesel engine to shut down; and the mud of discharging behind the slurry pump open flow is directly got back in the slurry tank; the staff is difficult for finding; after finding, go to close diesel engine again; diesel engine is in for a long time has big load carrying capacity; but the state of working under low-load easily causes the damage of diesel engine.
Summary of the invention
The purpose of this utility model provides a kind of slurry pump superpressure open flow arresting gear, control power engine autostop when can be implemented in after the slurry pump superpressure pressure release of safety valve open flow, and then slurry pump is also shut down.
Realization the utility model purpose is taked following technological scheme: a kind of slurry pump superpressure open flow arresting gear, comprise sensor, box body, data processing system, display device, alarm, relay, solenoid valve, power supply, be installed in the safety valve on the slurry pump, data processing system, display device are contained in the box body, described sensor is installed on the safety valve body, induction piece is embedded on the shear plate of safety valve, during the slurry pump normal pressure, sensor and induction piece position align; Described data processing system is connected with sensor cable; described data processing system is connected with the alarm cable; described data processing system is connected with the relay cable, and described relay is connected with the solenoid valve cable, and described electromagnetic valve drives the engine shutdown of slurry pump work.
Described box body is made of inner casing, shell, is provided with thermal insulating material between the inside and outside shell, is provided with device for automatic electrical heating in the inner casing.
The utility model is at safety valve not during superpressure; sensor just in time aligns with induction piece; indicator gate shows " normally "; when the slurry pump overpressure; when the safety valve shear plate is upspring; the one side shear plate is cut off safety pin open flow drilling fluid and is carried out pressure release; on the other hand; induction piece does not align with sensor with the shear plate displacement; sensor sensing is less than signal, and at this moment sensor sends electrical signal and gives data processing system, and data processing system receives and makes this device, display window show " superpressure " after electrical signal is handled; export electrical signal simultaneously and give alarm; make the alarm warning of ringing, also export the adhesive of electrical signal control relay simultaneously, the adhesive of relay control electromagnetic valve; the engine shutdown of controlling and driving slurry pump work after the solenoid valve adhesive, slurry pump are also shut down simultaneously.After removing fault, restart engine operation.Automatic electric heating and thermal insulation apparatus are set in the box body, can make this device be used for low temperature environment.
The beneficial effects of the utility model are: in the time of the pressure release of slurry pump superpressure safety valve open flow, and may command power machine, slurry pump autostop, thus guarantee device security.
