One of the features of the hydraulic drive is that it is easy to achieve overload protection. This means the overflow valve is active. It is through the opening of the valve port to keep the pressure of the system constant or limit the maximum pressure. The overflow valve can not only used as a s...

Cleaning method: The most common fault: the welding slag, rust, slag, etc. in the pipeline cause blockage or jam in the throttle hole, the guiding part, and the balance hole of the lower bonnet, causing strain and scratches on the curved surface of the valve core, the guide surface, and sealing. ...

The work of a vacuum tanker is hard and dirty. It exerts a lot of wear and tear on the materials, because it takes place in tough environments with tons of substances and liquids that may be inflammable or explosive. The suction task demands that the vacuum truck pump on the vehicle is as low-noi...

Like the 2BV water ring pump and the 2BE water ring pump, the SS304 material and SS316L material are often used. Most end users do not have professional material testing equipment. Many customers prefer to use magnets to simply test the raw materials are stainless steel or cast iron. 2BV water ri...

Overload refers to exceeding the specified carrying standard, that is, exceeding the rated load of the equipment itself. The general phenomenon is that the current become large, the electrical equipment temperature become higher, and the long-term overload of the line will reduce the line insulat...

The fluid should be filled in the casing before the pump work. The impeller will be rotated by the bearing with high speed. The fluid in the casing will be rotated at the same time.The fluid will absorb the energy when it be throw from the center of the impeller to the outside within the centrifu...

As it known to all, water ring vacuum pump in the general case use water as working fluid, in the process of water into the discharge to achieve the purpose of pumping air into vacuum state, and in the process of water absorption into sent by the pumping action of the water hitting the wall, impe...

When developing modern screw vacuum pumps the reduction of energy consumption has been given a high focus— it is now at about the same level of established oil-sealed rotary vane pumps or rotary piston pumps. To energy savings through modern screw vacuum pumps, similar opportunities arise when us...

Introduction: JZJX series roots-rotary pump system contains ZJ series roots pump as main pump and single or double stage rotary vane pump as fore pump. It is an ideal machine to achieve for low or high vacuum degree. Besides, the whole system will match the connecting pipe, valve, electric cabine...

1. Open cylinder and installation (1) Before dismantling the cylinder. Discharge oil from the vacuum pump (including liquid ring pump, rotary vane pump , rotary piston pump ,oil diffusion pump, dry scroll pump and so on ) Manually rotate the fan belt, discharge may have been gathered in the vacuu...
