When the diaphragm pressure gauge measures pressure, the working medium to be measured acts directly on the isolation diaphragm, upward deformation of the diaphragm occurs, and the medium pressure is transmitted to the spring tube through the filling liquid in the spring tube, so that the spring tube end is elastically deformed. By means of the linkage mechanism, the axis of the gear shaft is rotated so that the pointer indicates the measured pressure value on the dial.

Diaphragm pressure gauges and equipment are connected in the following forms:

A) Screw connection Diaphragm pressure gauge connection thread specifications are: M14*1. 5, M20*1. 5, G1/2, G3/8, NPT1/2, etc., also can be produced according to user requirements.

B) flange connection (including flange)

According to the Ministry of Chemical Industry HG, GB GB and Japan JIS, the United States ANSI and other standards.

C) Hygienic interface The sanitary interface is: nut type, bolt type, clamp type.

Diaphragm Pressure Gauge Use When measuring the pressure of general gases, water, and oil, we can use the general pressure gauge; when measuring the pressure of nitric acid, phosphoric acid, strong alkali, you can use stainless steel pressure gauge. However, the medium to be measured is highly corrosive (such as hydrochloric acid, wet chlorine gas, ferric chloride), has a high viscosity (such as glue), is easy to crystallize and solidified, and when a solid floater is used, the pressure gauge is used again. This is not feasible because 316 stainless steel will also be corroded by hydrochloric acid. Asphalt and solid floater will clog the pressure guide hole of the pressure gauge and make the meter inoperative. Diaphragm pressure gauges can solve these problems. We can choose different corrosion-resistant isolation diaphragms according to different strong corrosive media, so as to play the role of anti-corrosion. Due to the isolating diaphragm, it can block the high viscosity, easily crystallized and solidified medium from flowing into the pressure guiding hole to ensure the normal operation of the instrument. Therefore, diaphragm pressure gauges are widely used in the pressure measurement of the production process in the chemical industry, chemical fiber, synthetic fiber, petroleum, dyeing, alkali, food, pharmaceutical and other industrial sectors.

Someone may not clear that it would change the time, resulting in poor engine performance even damage to valves, if the teeth on the belt jump over the teeth of gear. So that`s why Tensioner Bearing exists. It keeps belt tension never be too low or too high.

The tensioner Bearing should be replaced when replacing the timing belt. And we are professional for the United States, Europe, Japan and other countries, to provide high quality and affordable tension bearing.

belt Idler Pulleys are provided with a series of radial reinforcing ribs to prevent deformation caused by the wedging action of the belt. 

The Timing Belt Tensioner is used to keep tension on the timing belt. The timing belt is a rubber belt that runs over and through a series of pulleys and gears. Over time, due to age and heat, the belt will stretch out. As the belt stretches it can become loose, so the tensioner needs to adjust the belt as needed to keep it tight.
