Abstract
The utility model relates to a weighing meter for continuously reducing liquor material. The utility model is characterized in that the utility model is composed of a frequency conversion liquor pump 2, a weighing liquor box 4 which is connected with the frequency conversion liquor pump 2 through a pipeline, a pressure balance cap 3 arranged on the weighing liquor box 4 and a weighing sensor 5. The utility model has high metering accuracy, can not be influenced by the factors such as liquor nature, pressure, etc., and the metering error can be controlled from +0.5 % to-0.5%.
Description
(1) technical field: the utility model relates to a kind of liquid material decrement measuring apparatus, the continuous decrement Weighing device of especially a kind of liquid material.Be mainly used in continuous measurement and the functions of physical supply of realizing Stabilized Soil, concrete macrotype set of equipments liquid material, as the weight metering and the feed of continous way Stabilized Soil, concrete mixing plant water and liquid additive.
(2) background technology: existing Stabilized Soil, concrete macrotype set of equipments liquid material continuous metering device adopt generally that the volume type measurement Law is common two types: a kind of employing liquid pump adds the adjustable fluid flow metered valve, by regulating the flow that flow valve changes liquid.Owing to there is not Displaying Meter, lack demonstration directly perceived, set and adjust very trouble, can only the dependence experience determine the flow of liquid.This device is subjected to the influence of liquid revolution speed, pressure, the measuring accuracy instability, and error in dipping is bigger.The another kind of liquid pump that adopts adds intelligent turbo flow meter, by regulating the flow that the liquid revolution speed changes liquid.Displaying Meter is housed on flowmeter, can shows the flow of liquid.Though overcome the trouble of setting and regulating, its measuring accuracy still is subjected to the influence of factors such as liquid essence, pressure, measuring accuracy is lower,
(3) summary of the invention: the purpose of this utility model is intended to improve the deficiency of above-mentioned prior art, and provide a kind of instantaneous delivery and integrated flow of can in good time dynamically showing, it is high and stablize to possess measuring accuracy again, and is not subjected to the continuous decrement Weighing device of liquid material of environmental factor interference.
The purpose of this utility model can reach by following measure: the continuous decrement Weighing device of liquid material is characterized in that it is the liquid case 4 of weighing that is connected by pipeline by frequency conversion liquid pump 2, with frequency conversion liquid pump 2, is installed in air pressure balance cap 3 and LOAD CELLS 5 on the liquid case 4 of weighing.
Compared with the prior art the utility model has following good effect: owing to take this structure to make liquid material decrement measuring accuracy height, and the not influence of factors such as liquid body essence, pressure, error in dipping can be controlled in ± 0.5% in.
(4) description of drawings: accompanying drawing is the utility model and liquid reserve tank 1 and working host 6 syndeton synoptic diagram
(5) embodiment: the continuous decrement Weighing device of liquid material, frequency conversion liquid pump 2 is connected with liquid reserve tank 1 by pipeline, and weigh liquid case 4 bottoms and working host 6 join.Filled with fluid in the liquid reserve tank 1 at ordinary times, having up and down, liquid level meter control feedway adds liquid.When the metering beginning, the LOAD CELLS 5 on the liquid case 4 of weighing is constantly imported the decrement controller with weight signal, after comparing through the processing of decrement controller and with setting value, and controlling liquid revolution speed, thereby the measuring accuracy of controlling liquid.Along with the outflow of liquid, the detected value of LOAD CELLS 5 constantly diminishes, and the changing value in the unit interval is exactly the flow of liquid.
Claims (1)
1, the continuous decrement Weighing device of liquid material is characterized in that it is the liquid case (4) of weighing that is connected by pipeline by frequency conversion liquid pump (2), with frequency conversion liquid pump (2), is installed in air pressure balance cap (3) and LOAD CELLS (5) on the liquid case (4) of weighing.
