Before using the pressure test pump system, simply set the upper limit pressure value on the electric contact pressure gauge, set the time required for holding pressure on the digital display time relay, and then use the remote control or press the test pump start button. When the size of the tested container is not equal, the operator can arbitrarily change the rotation speed of the pressure test pump motor by twisting the inverter knob during the pressure test, thereby achieving the purpose of adjusting the boosting flow rate and the boosting time of the pressure test pump. When the pressure reaches the target value set by the test pressure in advance, the system will automatically stop entering the pressure holding state. When the pressure keeping time reaches the equipment, the device will alarm through the buzzer and then automatically relieve pressure. The test water is directly returned to the pressure test pump water tank. The pressure recorder pressure acquisition system has the following features:
1. During the pressure test, the pressure test pump manufacturer can display the real-time pressure value and the real-time pressure curve, automatically record the pressure value and the curve change of the boost pressure-holding process and store and print it to the micro-printer, or export the data through the USB flash drive. Computer and other functions.
2, pressure test pump digital display recorder pressure acquisition system can be directly connected to the computer (laptop) through the data line, through the computer background software to observe the test situation and pressure values ​​and pressure curve in real time, and can be printed at any time through the computer to import data Test report, test report format electronic file can be edited at any time. The computer (laptop) is provided by the customer.
3. Remote control of pressure test pump manufacturer: The portable recorder pressure acquisition system is connected with the pressure test pump through the pressure sensor data line, which can be extended to achieve the purpose of remote data acquisition and safe pressure test!
4. The installation and commissioning of the equipment of the pressure test pump manufacturer shall be guided by the supplier's technical personnel at 7X24 hours. If the telephone guidance can not complete the installation and commissioning, the two parties agreed to collect the travel expenses of the installation technicians as appropriate, and the company can immediately send people to the demand side for installation and debugging.
2, how to use
(1) Preparation before use
a. Add enough lubricating oil in the gearbox to make the oil level reach the position of the oil level indicator line. The lubricating oil is N46 mechanical oil (or 40# mechanical oil).
b. Check for looseness at each threaded joint.
c. Check the insulation of the motor and starter to meet the electrical code requirements. For safe use of electricity, the whole machine must be reliably grounded.
d. Set up a clean water reservoir and ensure adequate water supply. Put the inlet pipe filter into the water reservoir and notice that the filter screen should not be exposed to the water surface.
Pressure test pump (2) operation process
A. Operation of specifications below 31.5 MPa (with relief valve)
a. Open the pressure relief valve handwheel and the relief valve adjustment nut.
b. Start the motor and run it under normal pressure for 5 minutes to check if the pump is running normally. If there is no abnormal sound and the pump discharge medium does not fluctuate significantly, the boosting operation can be performed at this time.
c. Close the pressure relief valve handwheel, slowly adjust the relief valve to slowly increase the system pressure. After the test pressure is reached, loosen the relief valve adjustment nut to remove the pump discharge pressure, and then stop (if the user needs it, it can be stopped) At this time, the pressure test pipeline is in an automatic pressure holding state.
d. After the pressure test is completed, open the pressure relief valve handwheel and remove the pressure of the pressure test line.
e. If used for constant pressure output medium, close the pressure relief valve handwheel, adjust the relief valve to reach the test pressure, and lock the lock nut.
B. Operation of 40MPa or more (without relief valve)
a. Open the pressure relief valve handwheel.
b. Start the motor and run it under normal pressure for 5 minutes to check if the pump is running normally. If there is no abnormal sound and the pump discharge medium does not fluctuate significantly, the boosting operation can be performed at this time.
c. Stop, close the pressure relief valve handwheel, jog the motor to increase the test pressure and stop. At this time, the pressure test pipeline is in the automatic pressure holding state.
d. After the pressure test is completed, open the pressure relief valve handwheel to remove the pressure in the pressure test line and the pump.
(3) Precautions during use
A. For specifications below 31.5MPa (with relief valve)
a. During the boosting process, if the pressure gauge pointer swings too much, the user's test piece volume is too small. At this time, * a pressure vessel with sufficient capacity is attached to the system (should comply with relevant national standards) or Other corresponding energy storage devices.
b. The boost can be performed by pre-adjusting the pressure jog boost.
c. If you accidentally overpressure, you can open the pressure relief valve handwheel, remove some pressure and then boost the pressure.
d. The test pressure shall not exceed the rated working pressure of the pump. Before the system is used, simply set the upper limit pressure value on the electric contact pressure gauge, set the time required for holding pressure on the digital display time relay, and then use the remote control or press the test pump start button. When the size of the tested container is not equal, the operator can arbitrarily change the rotation speed of the pressure test pump motor by twisting the inverter knob during the pressure test, thereby achieving the purpose of adjusting the boosting flow rate and the boosting time of the pressure test pump. When the pressure reaches the target value set by the test pressure in advance, the system will automatically stop entering the pressure holding state. When the pressure keeping time reaches the equipment, the device will alarm through the buzzer and then automatically relieve pressure. The test water is directly returned to the pressure test pump water tank.
