Embodiment Construction
[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0027] Such as Figure 1-Figure 2 As shown, the water meter calibration device includes the water meter calibration device with a voltage stabilizing device in the application number "201720642433.6", the application date is "2017.06.05" and the patent name is "water meter calibration table with a voltage stabilizing device". The water meter calibration platform with a voltage stabilizing device includes a control cabinet, a meter calibration platform body, a pressure tank and a water pump. The water inlet of the meter calibration station at one end of the meter calibration table body is connected to the water outlet of the pressure tank through a water pipe, and the water outlet of the meter calibration station at the other end of the meter calibration table body is connected to the top of the water storage tank through a water pipe. Between two adjac...

According to a water meter calibration device, a control cabinet comprises a cast iron base and a cabinet body, and a cabinet door is arranged on the front face of the cabinet body. A cast iron seat is arranged at the bottom of the cabinet body, the cabinet body is connected with the cast iron seat through the rubber block, the rubber block is bonded on the cast iron seat, and the screw rod is screwed with the rubber block through the bottom wall of the cabinet body. The cast iron seat comprises a pair of horizontal cast iron rods, a pair of vertical cast iron rods and a plurality of cast ironrods, wherein the included angles between the cast iron rods and the horizontal plane are acute angles or obtuse angles larger than zero, and the pair of horizontal cast iron rods and the pair of vertical cast iron rods are welded to form a rectangular structure. In combination with other structures, the defect of unstable performance caused by impact on an internal PLC control system and a frequency converter due to the fact that a control cabinet shakes without vibration reduction performance in the prior art is effectively avoided.
Description
technical field [0001] The invention relates to the technical field of water meter calibration, in particular to a water meter calibration device. Background technique [0002] After the water meter is assembled, it needs to be calibrated, that is, to check whether the water meter is accurate. The water pumps in the existing meter calibration stations pump water according to the natural frequency. When the water consumption changes, it is easy to cause the pressure to be too high or too low. At present, the manual valve on the pressure tank is used to release the pressure. Not only the efficiency Low and very unsafe. [0003] To solve the above problems, a water meter calibration device with the application number "201720642433.6", the application date "2017.06.05" and the patent name "water meter calibration platform with voltage stabilizing device" was launched. [0004] The water meter calibration platform with a voltage stabilizing device includes a control cabinet, a ...
