Description
Technical Field
The utility model relates to a coal mine machinery especially relates to a concrete pumping mechanism pressure flow detection device for coal mine.
Background
At present, the pressure and flow detection of the pumped concrete of a mining concrete pumping mechanism has two measurement modes, wherein the first mode is theoretical measurement: the theoretical pumping flow is obtained by measuring the swinging times of the oscillating cylinder per minute, multiplying the swinging times by the volume of the concrete cylinder and dividing the multiplied value by the suction rate; the other is to pump a certain volume of concrete, and the concrete pumping flow is obtained by lengthening the length or height of the delivery pipe under the corresponding length or height. The first detection method is too far from the actual pumping flow rate and cannot detect the pressure; the second detection mode has the disadvantages of high labor intensity, long time consumption, poor accuracy and great concrete waste.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a pressure and flow detection device of a concrete pumping mechanism for a coal mine, which reduces the test cost; the pumping mechanism achieves the most efficient use efficiency.
In order to solve the problems, the utility model discloses a pressure and flow detection device of a concrete pumping mechanism for a coal mine, which comprises a pumping mechanism, wherein the pumping mechanism is connected with a water return pipe through a straight pipe, and the pumping mechanism is detachably connected with the straight pipe through a sealing ring and a pipe clamp; the straight pipe and the water return pipe are also detachably connected through a sealing ring and a pipe clamp, a damping block is further arranged between the straight pipe and the water return pipe, a pressure gauge is arranged on the straight pipe, and a flowmeter is arranged at one end, close to the straight pipe, of the water return pipe.
Further, the manometer is connected with the straight tube through a flared straight-through joint body.
Furthermore, the tail end of the water return pipe is arranged above the pumping mechanism.
The beneficial effects of the utility model reside in that:
when the pressure flow detection device of the concrete pumping mechanism for the coal mine is used for detection, the used pump is used for feeding water and is recycled, so that the test cost is greatly reduced; the size of the damping hole is changed to simulate different industrial and mining environments to measure pressure, the length or the height of a corresponding conveying pipe can be calculated and simulated, and the flow value of the flowmeter is read, so that the use performance of the pumping mechanism is accurately tested, corresponding hydraulic and electric debugging is carried out, and the pumping mechanism achieves the most efficient use efficiency.
