KMJ SF6 Gas
Density Relay
It is
applicable for monitoring the SF6 gas density in a sealed vessel. It can show
gas density values on the site. When the gas density reaches the preset value,
the contact-making device will send alarm and control signals. It can be widely
used in electric equipment including SF6-insulated composite apparatus, circuit
breakers, pole-mounted switches, transformers and mutual inductors. It provides
solutions for new construction of transformer substations and inteligent reconstruction
of existing transformer substations.

What is the principle and characteristics of the pump test system?
Today, the level of science and technology is getting higher and higher, all kinds of products must be tested before production, to ensure the normal sale, now to say the principle and characteristics of the pump test system. Pump Test System Pump test system control of the main equipment for the 12 pumps, a group of six, a total of two groups, 12 pumps can work at the same time, long run, mainly used to test the reliability of the pump. The system in the design fully take into account the scalability, maintainability, high reliability, energy conservation, one-time investment to ensure long-term benefits. First, the pump test system principle 1, the purpose of this test is to examine the long-term failure mode of the pump, such as wear and tear, deterioration of performance, leakage and so on. 2, according to product characteristics, the pump daily continuous, trouble-free, in the closed tank circulation system to the end of the trial, the medium is clear water or coolant, the upper tank may be appropriate to join the abrasive, temperature and pressure can be adjusted. 3, the pump start, run, stop time and speed adjustable, as much as possible to simulate the actual working state of the car engine, such as start delay time, different speed of operation, stop delay time. 4, adjust the pressure on the import and export, so that the pump displacement to achieve the required lift or flow, observe and record the pump running status parameters, automatic recording pump running time, starting times, downtime, study the quality of use and life. Second, the characteristics of the pump test system 1, each pump own a heating tank, the main control of the temperature control part of the automatic control of the tank heating or constant temperature, constitute an intelligent temperature control system, each pump has its own temperature control system, Energy saving. 2, a set of 6 test pumps, sharing a set of water inlet and outlet control devices, pressure and speed measurement instruments, control units, enabling on-site display and adjustment of test parameters and test curve of the man-machine interface. Each group can be controlled separately. 3, Each group consists of programmable controller, man-machine interface, frequency conversion velocity modulation system, each water pump own temperature control system, the pressure examination and the rotational speed measurement control system, and the host computer union, realizes the centralized control, the record, the test report Print and real-time curve and historical curve display and other functions, constitute intelligent reliability testing and control system. 4, the use of virtual instrument detection technology to ensure that the process of control and control process parameters display and read data consistency, improve test accuracy. 5, Reliable testing and testing instruments and sensing system, according to the specification finishing calculation of the performance parameters to ensure the reliability of the test data, the test calculation accuracy of <= 0.5. 6, monitoring test process, automatic alarm and shutdown. What the experimenter did, just installed the pump, the switch button, and the computer. 7, good system scalability, maintainability and reliability of design, to ensure a one-time investment, long-term benefits.
