High Flow Test Pressure PumpWhat safety issues should be noted during use?
When purchasing, pay attention to the Model and flow rate of the high flow test pressure pump. If the selected Specification is not suitable, sufficient water output cannot be obtained, and the efficiency of the unit cannot be realized. If the test pressure pump does not start, it cannot output water. Check if there is a power outage, and if the plug is properly inserted; check if the low-pressure switch is malfunctioning and cannot be connected; check if the pressure switch or water level controller has a fault; check if the transformer and fuse are burnt out.
High Flow Test Pressure PumpThe function is to convert the mechanical energy of the power machine (such as electric motors, internal combustion engines, etc.) into liquid pressure energy, driven by the motor to rotate the cam. When the cam pushes the plunger upward, the sealing volume formed by the plunger and the cylinder body decreases, and the oil is squeezed out of the sealing volume and discharged to the required place through the one-way valve. When the cam rotates to the descending position of the curve, the spring forces the plunger downward, creating a certain degree of vacuum, and the oil in the oil tank enters the sealing volume under atmospheric pressure. The cam causes the plunger to rise and fall continuously, and the sealing volume periodically decreases and increases, allowing the pump to continuously suck and discharge oil.
When installing the high flow test pressure pump, the cable should be overhead, and the power line should not be too long. Do not pull the cable forcefully when the machine is emitting to avoid breaking the power line. Do not submerge the test pressure pump in mud, as this may cause poor heat dissipation and burn out the motor windings. If the solenoid valve malfunctions, it cannot effectively stop the water; check method: close the pressure tank ball valve, if there is still wastewater, it can be determined that the solenoid valve is faulty); in another case, close the inlet solenoid valve and then reopen it. If the machine operates normally, it indicates that the water pressure is too high, causing the solenoid valve to close inflexibly. Then consider adjusting the inlet valve to reduce the water pressure. Check valve pressure relief (check method: close the inlet solenoid valve, if there is still wastewater, it can be determined that the check valve is leaking pressure).
Do not letHigh Flow Test Pressure Pumprun for a long time under overload, do not pump water with a high sand content, and do not let the test pressure pump dehydrate for too long to avoid overheating and burning out the motor. During the operation of the unit, operators should always observe whether the working voltage and current are within the range specified on the nameplate. If not, stop the motor, identify the cause, and eliminate the fault. Regularly check the motor. If cracks are found on the lower cover, or if the rubber sealing ring is damaged or ineffective, it should be replaced or repaired in time to prevent water from entering the machine.
In addition to the different requirements of the conveyed object on the structure of the high flow test pressure pump, there are new requirements forHigh Flow Test Pressure Pumpthe internal or external structure in terms of installation form, pipeline layout, maintenance, etc. At the same time, various manufacturers have incorporated their own ideas into the structural design, further enhancing the diversity of the test pressure pump structure.
