Explosion-proof electrical contact pressure gauge: explosion-proof electrical contact pressure gauge flameproof enclosure has good flameproof performance, so the explosion-proof electrical contact pressure gauge has the effect of spark or arc in the normal working process, in addition to being able to withstand the explosive gas inside the shell. In addition to the explosive pressure generated in the event of an explosion, the mixture can effectively prevent the heat energy generated from this from spreading to the outside, but can only slowly spread outward inside the housing along the tiny gaps between the flameproof joints. At this time, the temperature that has been transmitted to the outside of the housing has fallen below the ignition temperature of the explosive gas mixture, so it does not cause the explosion.
Explosion-proof digital (pointer) display pressure gauge: high precision, high stability, error ≤ 1%, internal power supply, micro power consumption, stainless steel shell, strong protection, beautiful appearance. Explosion-proof digital display pressure gauges are widely used in petroleum, chemical, metallurgy, power stations and other industrial sectors or electromechanical equipment to measure the pressure of various fluid media with explosion hazard. 
1. Preparation: Clean the working surface and seals, and check if the seals are damaged or deformed.
2. Apply lubricant: Apply a layer of lubricant to the seal and sealing groove.
3. Install the seal: Place the seal into the sealing groove, ensuring that the seal is fully embedded in the groove.
4. Install O-ring: Install the O-ring above the seal, ensuring that the O-ring is fully inserted into the groove.
5. Install the piston rod: Insert the piston rod into the seal and O-ring, ensuring that the piston rod fits tightly with the seal and O-ring.
6. Install the sealing sleeve: Place the sealing sleeve on the piston rod to ensure that it fits tightly with the piston rod.
7. Tighten the nut: Use the nut to fix the sealing sleeve on the hydraulic cylinder, ensuring that the sealing sleeve is secure.
8. Check the sealing effect: Operate the hydraulic cylinder and check if there is any leakage in the sealing element. If there is any leakage, reinstall the sealing element.
