Product Introduction: Pressure Gauge Cover Pressure gauge cover is a protective matching part for mud pump pressure gauges in oil drilling, geological exploration and horizontal directional trenchless construction. It is mounted outside the pressure gauge to shield the gauge core from external collision, mud splashing, sand impact and mechanical vibration damage. Integrally formed with high-strength cast steel or thick alloy steel and precision machined, this cover features high structural toughness and impact resistance. The reserved transparent observation window allows real-time reading of pressure data without removing the cover. The built-in sealing groove fits with rubber gaskets to block mud, rainwater and dust infiltration, preventing internal gauge failure caused by slurry contamination. Optimized curved structure disperses instantaneous hydraulic shock and external impact force, avoiding deformation and cracking. Standard thread and mounting hole sizes realize great interchangeability, matching most common mud pump pressure gauge assemblies. The whole surface undergoes anti-rust paint treatment to resist erosion of acidic and alkaline drilling fluids and outdoor humid environments. Quick-release installation structure enables convenient disassembly for gauge inspection, calibration and replacement, greatly improving on-site maintenance efficiency. It effectively prolongs the service life of precision pressure measuring instruments, ensures accurate and stable pressure monitoring during construction, reduces instrument damage and replacement costs, and enhances the safety of mud pump pressure control system. It is an indispensable protective accessory for drilling slurry circulation equipment.
