It is mainly used to indicate the change and quantity of pump pressure. Pump pressure is an important parameter to calculate the hydraulic parameters and pressure loss of the borehole, and an important factor to affect the drilling efficiency. In addition, it is also an important parameter to help operators understand whether drilling is normal. When the drill string leaks in the hole, the drill bit water hole is blocked, the drill tool is twisted and the pump fails, there will be abnormal reflection on the pump pressure gauge. The experienced operator can judge the cause of the failure according to the change of the pump pressure gauge to ensure the safety and smooth drilling. Therefore, pump pressure gauge is one of the most basic drilling parameter instruments.
The Vibration-resistant Slurry Pressure Gauge
We have a young, high-quality, pioneering scientific research team that combines modern information technology to research and develop high-quality Stainless Steel Hydraulic Digital Pressure Gauge,Dial Pressure gauge,Torque Pressure Gauges. We continue to improve our own technical strength, so that some of our technical fields have even approached or reached the advanced level of the same industry. The competitive society makes us breathless sometimes. The life full of bitterness and bitterness makes us confused sometimes. My team makes every product with sincerity. We insist on spreading us to the whole world with good products and infecting the people around us with sincere heart. Our products meet international quality standards and are extremely cost-effective.
The pump pressure gauge is a pressure gauge used to measure the fluid pressure, which is mainly used to indicate the change and quantity of the pump pressure. Pump pressure is an important parameter to calculate the hydraulic parameters and pressure loss of the borehole, and an important factor to affect the drilling efficiency. In addition, it is also an important parameter to help operators understand whether drilling is normal.

The isolator is mainly composed of two parts. One part is the space inside the rubber spacer, which allows the well flushing fluid to enter and is isolated by the rubber spacer. The other part is the upper space of the rubber spacer, which has two outlets. One is connected to the pressure gauge (or through the damper), and the other is used to fill the upper space with clean transformer oil or drain the oil. During normal operation, the upper space of the entire spacer is filled with pressure oil. Therefore, when the well flushing fluid enters the rubber sleeve at a certain pressure, it will exert force on the elastic rubber sleeve to make it deform, thus transforming the pressure of the well flushing fluid into the pressure of hydraulic oil without loss, which is reflected by the pressure gauge. The structure and working principle of pressure gauge are the same as that of general liquid pressure gauge.
