Technical field
The utility model relates to a kind of rig pump, and particularly a kind of slurry pump is suppressed pump pump trip device.
Background technique
The state-detection of slurry pump is mainly and measures slurry pump pump pressure at present, and pump pressure detection device is generally supporting by drilling machine instrument or automatically controlled producer, mainly pressure transmitter, pressure signal processing unit, signal transmission unit and display device etc., consists of.Although pump pressure detection device can detect in real time and show pressure signal, cannot control the working state of slurry pump when pressure signal is abnormal.Can only be to tell driller that present pump pressure is abnormal by demonstration, then by driller, be controlled the working state of slurry pump, have certain hysteresis quality.
The drilling mud pump that machine dimensions drill and electric drilling machine use at present all adopts safety valve as safety protection.Safety valve is a kind of safety protection valve; its flap is normally in normally off, and the pressure medium in slurry pump raises, and while surpassing specified value, flap promotes stem shear latch; safety valve is opened, by discharge mud outside system, prevented that in slurry pump, pump pressure surpasses specified value simultaneously.
Mud relief valve is commonly used Lever and weight loaded safety valve, due to slurry pump work under bad environment, the reason such as vibration is large and weather conditions are poor, often can cause the flap of mud relief valve and valve rod to be stuck.At this moment as long as suppress pump phenomenon, be just easy to cause occurring life accident and equipment accident.At situ of drilling well, staff also must per tour inspection and is maintained once safety valve, if maintenance also may cause the open-shut device rust of safety valve dead not in time.
There is following deficiency in existing slurry pump:
1. in slurry pump working procedure, while safety valve being opened if there is abnormal rising of pump pressure, if field personnel not in time do not find and termination of pumping, also may cause relief tube to come off because of overpressure, this bring life risk also can to the staff on side.
2. slurry pump, when suppressing pump or when pump pressure raises extremely, cannot cut off slurry pump power source automatically, can only lean on mud relief valve work to shield; but after mud relief valve work; relief tube pressure is larger, easily causes security incident, and this is also precedented at each elephant.
3. larger to slurry pump and staff harm when mud relief valve lost efficacy, when serious, may cause air bag to fly away, the water hose phenomenon such as come off, thus cause the generation of casualty accident.
4. cannot and need to select slurry pump protection setting value (0-35MPa) according to field working conditions.
5. existing slurry pump Protective system, needs maintenance every day, time-consuming, effort.
