Maintenance of piston manometer

Maintenance of piston pressure gauge: 1. Always keep the pressure gauge clean and do not put it in an environment with excessive humidity to avoid corrosion. 2. The quick connector and O-ring at the lower end of the piston cylinder are easy to be damaged. If leakage is found, it should be replaced. 3. The liquid level in the oil cup should always be higher than the upper end face of the oil cup filter cover. If it is ignored, air will enter the preload pump, resulting in the failure of the preload pump. At this time, the oil inlet joint of the preload pump should be loosened to make the air flow out with the liquid. When the liquid continuously flows out, the joint can be tightened to restore the function of the preload pump.

Beijing Million Electronic Science and Technology Center is a large-scale instrument manufacturer and seller. Its business fields mainly include: gas detectors, metal detectors, environmental protection equipment, medical care, laboratory instruments, chemical instruments and equipment, agricultural instruments, electromechanical equipment, fire safety equipment, power communication equipment, etc., covering almost all industries. The piston and cylinder of JC50 1-CV-600T piston manometer are finely ground, with minimal roundness error and clearance. The working medium is sebacate, which has low viscosity, greatly improving the piston rotation duration, correspondingly reducing the piston descending speed and improving the piston resolution. Low price, high cost performance and convenient use.
