The BC-200A pump stroke counter produced by Shenyang Xinyulin Petroleum Machinery Co., Ltd. is a professional instrument for oil drilling operations, mainly used to monitor the working status of reciprocating mud pumps. The following is a detailed analysis of its features, working principle and main functions.
I.Main Features
The BC-200A pump stroke counter has the following outstanding features:
Excellent moisture-proof and waterproof performance: It adopts a fully sealed structure. The signal connectors and buttons are all designed as waterproof types, with a waterproof rating of IP68. It can be immersed in water at a depth of 1 meter for 12 hours without water ingress. Intrinsically safe explosion-proof: the overall power consumption is very low (about 150 mu), small signal current sensor (about 5 mu), compliance with the safety standards of nature, suitable for oil drilling and other inflammable and explosive environment. Multi-channel independent measurements: support up to three channels signal input, can connect three mud pump at the same time, and shows that the pump stroke data independently. Data memory function: after shutdown automatically save all the data (such as the total number of stroke), replace the battery while the operation quickly (suggest no more than three minutes) also can retain data. Strong environmental adaptability, wide working temperature range (- 30 ℃ ~ 70 ℃), able to adapt to the drilling site conditions. Low power consumption and long life: adopt two ER26500 3.6 V industrial lithium battery power supply in parallel, random cells usually can use about 1 year.
II.Working Principle
The working principle of the pump stroke counter is based on magnetic sensing technology:
Signal acquisition: Install magnetic blocks on the piston or reciprocating motion parts of the mud pump, and correspondingly install HR-3V magnetic sensors. When the piston moves back and forth once, the magnetic sensor will detect a change in the magnetic field. Signal conversion and processing: sensor converts mechanical movement to a square wave signal (low level 0 v, high level 3 v). This signal is transmitted to the main controller via a cable. Calculation and shows: the controller inside the microcontroller (such as 51 series) and timer/counter (e.g., 8253), by the signal processing calculation per unit time of pulse number (namely frequency, unit times/min) and the total number of pulse (i.e., the accumulative stroke). Data output: the final result, through the LCD display shows, for the driller's personnel to provide real-time, accurate pump stroke frequency and the total number of stroke, and estimate the instantaneous flow rate and the total injection of mud.
III.Main Functions
The BC-200A pump stroke counter has the following core functions:
Multi-pump independent measurement and display: It can simultaneously measure and independently display the real-time pump stroke numbers (0-19999) of three slurry pumps (Pump 1, Pump 2, and Pump 3). Pump stroke frequency switch display: "choose" button on the panel, recycled switch shows three pump of pump stroke frequency real-time (0-999 times/min). Accumulative total shows: automatic calculation and displays the total number of pump stroke three pump (0-99999), the sum of the total injection to mud. Data memory and reset: data is automatically saved after shutdown. Can be through the "reset" button will all count goes to zero. Power management: adopt double lithium battery, battery is enough, long battery life. It is equipped with a power switch that can turn off the display screen separately to save power.
The BC-200A pump stroke counter of Shenyang Xinyulin is a reliable and professional oil drilling instrument. Its features such as multi-channel independent measurement, intrinsically safe explosion-proof, excellent waterproof performance and data memory function enable it to accurately and reliably monitor the working status of the mud pump, providing key data support for driller personnel. It is an indispensable tool in drilling operations
