VB-Z720 dual channel water swing monitor I. Overview
The HZD-L/W vibration monitor can be connected to a variety of vibration sensors, such as magneto-electric speed sensors or eddy current sensors. When connected to the speed sensor, it can measure the vibration intensity (vibration speed RMS) or displacement (vibration amplitude) in the vertical or horizontal direction of the casing or housing.
When connected to an eddy current sensor, the radial and horizontal radial vibrations of the rotating machine shaft can be measured. The digital display can separately display the vibration values ​​of the two channels. Each channel has an independent alarm, hazardous circuit and relay contact output. Accurately set alarm and hazard values, alarms and dangerous delay times, and view alarm and hazard settings at any time.
The standard voltage (1~5V) or standard current (4~20mA) corresponding to the vibration value can be independently output for use by a computer, data collector, recorder or other automatic control system. Other voltages or currents can also be output as needed. The gain of each channel is automatically adjusted for easy calibration of the system.
All functions are controlled by a single computer, and the parameter settings are all completed by the buttons. The adjustment is convenient, the precision is high, stable and reliable.
The VB-Z720 dual-channel water swing monitor measures the vibration of the casing or structure relative to the free space, ie absolute vibration. It is especially suitable for machines with ball bearings. In this machine, the vibration of the shaft can be transmitted more. On the case, the monitor can be equipped with a magneto-electric speed sensor for continuous measurement and protection of the rotating machine. The sensor should be installed with special care, without causing the sensor amplitude to be reduced, and the frequency influence to be changed or generated. The signal does not represent the actual vibration of the machine. This is especially useful for motors, compressors, fans, etc. where a large number of vibration points need to be measured.
The main function realizes intelligent processing: alarm I value, II value can be adjusted by panel button to adjust the range value, no potentiometer adjustment, convenient on-site debugging
30 seconds without pressing the operation button, you can return to the running state. The rear panel has a current output terminal proportional to the vibration amplitude value. The recording output has an alarm delay function (any setting is 0~25.5 seconds).

Bearing vibration monitor
Introduction:
It is equipped with an eddy current sensor to measure the radial vibration of the shaft of various rotating mechanical rotors. Suitable for the design of the rotating mechanical device TSI, it can be widely used in electric power, machinery, chemical, metallurgical and other industries. Provides measurement of various parameters and prediction of early faults for safe operation of rotating machinery
RDXZ-2/2N/2NA axis vibration monitor
The main function:
Monitoring and protection of bearing bush vibrations of rotating machinery such as steam turbines, coal mills, fans, reducers, pumps, centrifuges, balancing machines, and air compressors.
Function Description:
The measured value and alarm set value can be displayed on the LED digital tube.
When the alarm setting value is exceeded, the alarm indicator lights up, and the switch signal is output on the rear panel to protect the monitored equipment. The alarm setting delay adjustment is in the range of 1-60 seconds to prevent false alarms caused by on-site interference. .
It has a current output interface that can be connected to devices such as computers, DCS, PLC systems, and paperless recorders.
It has upper and lower power detection function, sensor drop detection function, and cut off alarm and stop output circuit at the same time, effectively suppressing instrument false alarm.

Pneumatic Pump is a new type of transport machinery, is the most novel type of pump in China.Using compressed air as the power source, all kinds of corrosive liquids, granular liquids, high viscosity, volatile, inflammable, highly toxic liquids can be exhausted by light absorption.Invented by American engineer William wilton, the pneumatic pump was introduced to China.There are five kinds of materials commonly used: plastic, aluminum alloy, cast iron, stainless steel and teflon.According to different liquid media, Diaphragm Pump adopts buqing rubber, chloroprene rubber, fluoro rubber, polytetrafluoroethylene, polytetrafluoroethylene respectively.The early domestic customers bought through the importer agent, the price is expensive and the maintenance is complicated.With the development of industry, the market share of domestic Pneumatic Diaphragm Pump has exceeded that of imported products.In order to install in a variety of special occasions, used to pump a conventional pump can not pump the medium, all achieved satisfactory results.
