Description
Technical field
The utility model belongs to provides high pressure, the continuous pressurized test instrument of high-volume hydraulic oil, particularly a kind of pressurized test platform continuously.
Background technique
The developing trend in colliery is in maximization, and the mechanization degree that colliery uses is more and more higher, and medium-and-large-sized mine achieves mechanization comprehensive exploitation substantially, along with the oil cylinder, the jack that increase a large amount of use all size of down-hole support apparatus.Need the feed flow providing high pressure, large discharge during large-scale support apparatus test experience, common pumping plant can only provide the low pressure of below 40MPa, cannot meet user demand, it is little to there is boosted flow in the existing supercharging equipment in market, the defects such as discontinuous, efficiency is very low, and feed flow is unstable.
Model utility content
The purpose of this utility model is to provide a kind of pressurized test platform continuously, and it is rational in infrastructure, easy to operate, when can realize detecting the equipment such as oil cylinder, jack, provides high pressure, the hydraulic oil of large discharge, and realizes providing hydraulic oil continuously.
The purpose of this utility model is achieved in that a kind of pressurized test platform continuously, the table top of test stand arranges pressure gauge, the Joystick of 3-position 4-way P type hand-operated direction valve and operating button, oil hydraulic circuit pressurizing cylinder, hand-operated direction valve, one-way valve and safety valve connected to form by connecting pipeline is installed in the inside of test stand.
The accessories such as pressurizing cylinder, control valve, one-way valve, safety valve are connected to form pipe-line system by the utility model, two pressurizing cylinder and other pipeline valve part, pressure gauge, main control valve are installed in test-bed and form continuous pressurized test platform, realizes the object of large discharge continuous high-efficient supercharging by the alternately supercharging of two pressurizing cylinders.
Working procedure of the present utility model is:
External pumping plant realizes supercharging to pressurized cylinder upper and lower cavity feed flow by the pressure difference of upper and lower cavity by one-way lock, makes two pressurized cylinder alternately operatings realize continuous high-efficient supercharging work by the alternately manipulation of control valve.
Delivery pressure is shown by the pressure gauge that test stand is installed.
The utility model provides a kind of large discharge, high pressure, continuous, efficient pressurization system, and it is rational in infrastructure, easy to operate, achieve when the equipment such as oil cylinder, jack is detected, there is provided high pressure, the hydraulic oil of large discharge, and achieve and provide hydraulic oil continuously.
Accompanying drawing explanation
Be further described the utility model below in conjunction with accompanying drawing, Fig. 1 is main TV structure schematic diagram of the present utility model, and Fig. 2 is the left TV structure schematic diagram of Fig. 1, and Fig. 3 is hydraulic scheme of the present utility model.
