The benchtop pressure pump is an indispensable auxiliary device in the pressure generating system. However, when it comes to the problems in the specific operation and operation of the pressure pump, there are not many users who can truly solve it. So today we have the following suggestions for pressure pumps:
Hope to give users some help.
The correct operation method of the pressure pump and the solution to the common problems: Pressure source leakage
1. The gauge connected to the threaded surface is not even (straight thread)
2. Internal leakage of pressure source
3. When the instrument being checked is a tapered thread
4. There are foreign objects in the system, there are stolen goods on the sealing surface of the valve
5. The pressure source outlet seal is damaged
6. The detected instrument has a leakage solution
1. Connect with a transition joint, add PTFE flat pad on the end face and tighten the tool with the inspection table
2. Connect the standard instrument to the pressure source. Other output ports are screwed tightly with random screw plugs. Pressurized to test the tightness. If none of the above phenomena are observed, the internal components will be damaged. If necessary, they will be returned to the manufacturer for disposal.
3. Must use the corresponding transition joint plus raw tape with tools to tighten
4.Multiple step-up, rapid pressure relief flushing seal surface, if necessary, return to the manufacturer for repair
5. Replace the seal
6. Replace other instruments and try again to determine whether the meter is leaking II: Difficulties in pressure creation
1. The seal is damaged
2. Positive/negative pressure switch position
3 exhaust valve does not close
4. Lifting pressure handle off (2000B)
5. The regulator valve does not open
6. The detected instrument does not tighten the corresponding solution
1. Replace the seal again
2. Reconfirm the positive/negative pressure position
3. Close the exhaust valve
4. Turn the handle clockwise
5. Open the regulator valve
6. Tighten the standard and the instrument to be inspected by three: the correct operation method of the bench-top liquid pressure pump
1 Positive detection Open the output 1 and output 2 plugs, open the regulating valve, adjust the fine adjustment to the appropriate position to lock the emptying valve, gently operate the lever to make the pressure-guiding liquid to the output port, install the standard table and be calibrated, The operating lever is boosted to the vicinity of the verification point, and the verification point is approximated by fine adjustment, and the full range is detected point by point.
2 Backhaul inspection According to the regulations, after two readings at full scale, slowly depressurize to the verification point with fine-tuning, point by point detection, until zero, when the fine-tuning operation can not be reduced, you can gently open the empty valve buck. When the pressure drops slowly under high pressure, the regulator valve can be locked.
Four: Precautions for bench-top liquid pressure pump
1 Select a flat and easy-to-operate countertop to avoid entering the environment with highly corrosive gas and dust particles.
2 output 1, output
2 is a dedicated quick interface, face seal, when the instrument is installed, without any tools, tighten evenly and tightly, about when the sealing surface is tight,
Twist 2~3 turns.
3 The instrument to be inspected shall be properly cleaned to prevent contamination from entering the detection circuit.
4 When leverage pressure is heavy, it is easier to fine-tune the pressure.
5 Regularly check the lower lock nut, the connection is firm, the connection is not reliable, in case of high pressure, may cause collapse.
MORGAN series steel rolling guide is a kind of equipment used in the steel rolling process, it helps to guide and control the rolling direction and position of steel in the rolling mill. This equipment usually consists of a set of rolling guide wheels that can be adjusted as needed to ensure the correct position and orientation of the steel in the rolling mill.
MORGAN series rolled steel rolling guides have the following features and advantages:
1. High precision: The guide wheel adopts high-precision bearings and transmission devices to ensure the smooth and accurate movement of the guide wheel, thereby improving the rolling accuracy of steel.
2. Wear-resistant and durable: The surface of the guide wheel has been specially treated, which has good wear-resistant performance, and can be used for a long time without damage during high-speed rolling.
3. Flexible adjustment: The guide wheel can be adjusted according to different rolling requirements, including adjusting the position, angle and spacing of the guide wheel to suit steel products of different sizes and shapes.
4. High efficiency: The design and movement of the guide wheel can minimize the sliding and deflection of the steel, and improve the rolling efficiency and output.
5. Safe and reliable: The guide wheel is equipped with a safety protection device, which can prevent the steel from falling off the guide wheel or the guide wheel fails, ensuring the safety of operators and equipment.
In a word, MORGAN series steel rolling guide is a key equipment, which can effectively guide and control the rolling of steel in the rolling mill, improve rolling precision and efficiency, and ensure the quality and safety of steel.
