Description
Technical field
The present invention relates to a kind of wiper brake gear.
Background technology
In pigging and detection process are carried out to oil-gas pipeline, the general laws and regulations requirement pigging equipment speed of service is 3.5~
5m/s；Pipeline detection equipment preferably detects the quality of data to obtain, it is desirable to which the speed of service of equipment is less than 5m/s；Electromagnetism
The equipment such as detection, ultrasound detection then require that its speed of service is less than 2m/s.Wiper by pipeline climb and fall section, bending section,
Speed is changed greatly when hydrops, product sand and fouling section, and directly using conventional wiper, it is impossible to meet speed control requirement.
Existing oil-gas pipeline wiper speed control method is active control mode and passive control mode.
Active control uses by-passing valve control mode, and its technical scheme is：Wiper speed or use are gathered with mileage wheel
Acceleration transducer obtains wiper speed；Electric-control system is to signal transacting；The opening degree of eduction valve is adjusted by motor；
Again by pressure difference before and after eduction valve aperture regulation wiper, wiper motive force is adjusted, so as to control the wiper speed of service.
Passive control mode is by adjusting the pressure medium and flow of arrival end and the port of export in pigging operation come indirectly
Control wiper speed.Because the compressibility of gas, passive control mode is often difficult to reach preferable speed control effect, clearly
Pipe device easily causes impact because speed is excessive, the problems such as causing wiper and pipe damage.
Patent CN201310496586.0 discloses a kind of mechanical tube cleaner speed control, and the program uses semidecussation
Belt transmission obtains complex working condition in the wiper speed of service, pipeline and easily causes belt slippage.
Patent CN201410708220.X discloses a kind of wiper speed control with hydraulic system, patent
CN201520301095.0 discloses a kind of wiper speed control, and scheme described in above-mentioned two patent brakes hydraulic control masterpiece
With on the scroll wheel of controller rear end, when accumulator Preliminary pressure-filled is too high or pipeline in have wax deposition or wiper speed mistake
When fast, the easy locking of controller trailing wheel causes trailing wheel eccentric wear to deform, speed control is had undesirable effect.
Current active control mode controlled motor consumption electric energy, the accumulator electric-quantity that wiper is carried is limited therefore long
It is restricted apart from pipeline cleaning.On the other hand, the by-passing valve control program of automatically controlled mode is because it is contemplated that pipe interior medium, pipeline shape
The factors such as shape and become complicated.It is general to insulate one section of liquid using two closed type wipers when pipe ultrasonic ripple is detected
Post, ultrasonic detecting equipment, which is immersed in liquid, uses fluid as couplant.Under such a operating mode, wiper front and back end medium
It can not communicate, so by-passing valve control mode is using being restricted.In pipeline discharge opeing operation, promote clear from rear end using gas
Pipe device is run forward, and liquid is pushed away and scans out pipeline by wiper.In such a operation, wiper front and back end medium can not equally connect
Logical, otherwise liquid can aerial drainage time wiper rear end.State's internal bypass valve active control mode wiper is still immature, and external such is clear
Pipe device rents expensive, and country's oil-gas pipeline pigging is still based on passive control mode at present.
Therefore, develop that the wider array of wiper active controller of applicable working condition is significant and prospect of the application.
