Service life is longer；On the contrary then reliability is lower, the service life is shorter.After testing, the existing hydraulic actuator fluid grades of FAST have generally exceeded the standard,
Serious actuator fluid grade reaches NAS14 grades.It has been found that there are several actuators to can not work normally because gear pump is worn, there is number
Hundred actuator pressure holding functions are lost.And gear pump abrasion and the forfeiture of pressure holding function with oil cleanliness is exceeded direct pass
System.Therefore extremely urgent to the oil strain work of live 2225 hydraulic actuators.But the debugging efforts of FAST telescopes can not be because
This delays, so in the case that ensureing that normally debugging completion actuator oil strain is that actuator maintenance work needs to solve to FAST telescopes
Certainly the problem of.
FAST projected lives are 30 years simultaneously, and the actuator service life is at least 10 years.Therefore clear to the fluid of live actuator
Detection, filtering and the replacement of cleanliness are the routine works of actuator maintenance.And there are the following problems for existing product：
1, it has a single function.Most of product only has a function, such as detects or filters, or even has detection and filter one
Equipment.But it has no and replaces function for fluid, be unsatisfactory for the demand of FAST maintenance works.
2, volume is larger, and product is heavy.Most of product element is more, system complex.Therefore small product size is big, and product is heavy
Weight.It is not suitable for FAST actuator maintenance works.
Utility model content
For problems of the prior art, the purpose of this utility model is to provide a kind of big radio hydraulic oil to detect
Filtering and the portable unit replaced, not influencing debugging and in the case of observation mission, it is convenient, effective, economically solve it is existing
Topic is sent one's regards to, to improve actuator reliability and service life.Meanwhile for FAST look in the distance mirror actuator long term maintenance and maintenance worker
Make.
To achieve the above object, the utility model uses following technical scheme：
A kind of big radio hydraulic oil detection filtering and the portable unit replaced, the portable unit include motor, gear pump,
Particle collector, flowmeter, filter, safety valve, check valve, three quick-release connectors and differential pressure pickup；Wherein,
The motor is connect with the gear pump, and the first quick-release connector is connect with the oil inlet end of gear pump；Gear pump
Oil outlet end is connect with the oil inlet end of the particle collector；The oil outlet end of particle collector is connect with the flowmeter oil inlet end；
The oil outlet end of flowmeter is connect with the oil inlet end of the filter；The oil outlet end of filter is connect with the second quick-release connector；It is described
The oil inlet end of safety valve and the oil outlet end of gear pump connect；The oil inlet end of safety valve oil outlet end and gear pump connects；Third quick change
Oil circuit connection between connector and flowmeter and filter；The oil inlet end of the check valve and the oil outlet end of filter connect, single
The oil inlet end of oil outlet end and filter to valve connects；One end of the differential pressure pickup is connect with filter oil outlet end, another
End is connect with filter oil inlet end.
Further, the Opening pressure of the check valve is more than itself damping of the filter.
Further, the set pressure for safety valve is higher than the Opening pressure of the check valve.
The utility model has following advantageous effects：
The utility model can solve the current fluid cleaning of actuator in the case that not influencing FAST telescope debugging efforts
Excessive problem is spent, while the utility model also meets FAST actuator long term maintenance maintenance work demands.For there is similar demand
Large Hydraulic System, also can accordingly increase the size and specification of each element in the utility model to meet.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Specific implementation mode
Hereinafter, the utility model will be described more fully with reference to the accompanying drawings, shown in the drawings of showing for the utility model
Example property embodiment.However, the utility model can be presented as a variety of different forms, it is not construed as being confined to describe here
Exemplary embodiment.But these embodiments are provided so that this disclosure will be thorough and complete, and by the utility model
Range is fully communicated to those skilled in the art.
Applicant is according to FAST telescope hydraulic actuator maintenance work demands, it is proposed that a kind of portable liquid pressure oil
Detection filtering and more exchange device.To solve current hydraulic oil cleannes excessive problem, while being also that FAST hydraulic actuators are long
The work of phase care and maintenance provides safeguard.
As shown in Figure 1, the utility model provides a kind of portable unit of the big detection of radio hydraulic oil filtering and replacement, it should
Portable unit includes that motor 1, gear pump 2, particle collector 3, flowmeter 4, filter 5, safety valve 6,7, three, check valve are fast
Changing-over head and differential pressure pickup 9；Wherein,
Motor 1 is connect with gear pump 2, and the first quick-release connector 8.1 is connect with the oil inlet end of gear pump 2；Gear pump 2 goes out
Oily end is connect with the oil inlet end of particle collector 3；The oil outlet end of particle collector 3 is connect with 4 oil inlet end of flowmeter；Flowmeter 4
