PISTON

Piston

1. The piston is the core components of reciprocating pump types such as drilling mud pump it is generally a structure composed of a polyurethane outer layer and a metal framework inside and outer layer wear-resistant resistant to corrosion by various media inner layer metal provide strength support and base sealing ring safeguard cavity sealing property mainly applied to performing reciprocating motion within the pump body come true fluid transportation it is oil drilling solid control system corollary equipment one of the key vulnerable components

   

2. The piston is installed inside the pump driven by the power end perform reciprocating motion when the piston moves backward the pump cylinder volume has increased and loss of pressure the inlet valve open the medium is sucked into the pump cylinder when the piston moves forward the pump cylinder volume has decreased pressurizing the drainage valve is open the medium is pushed out of the pump cylinder pass the repetitive cycle come true the continuous transportation of the medium at the same time reduce wear and tear of the outer layer material improve the sealing effect
3. During installation it is necessary to ensure a reliable connection between the piston and the piston rod and adjust the coaxiality avoid uneven grinding before operation examine cleanliness of the inner wall of the pump cylinder ensure there are no impurities start by conducting a low-pressure test run initially confirm no leakage no congestion as the pressure gradually increases in service detect pressure and temperature regularly check the wear condition of the piston pressure needs to be released during shutdown and flush pump chamber avoid residual media corrosion of the components. Replace them promptly after they have become excessively worn

   

4. The piston is mainly applied to oil drilling mud fluid transporting drilling fluids containing sand and solid particles it can also be used for other reciprocating pumps are used to convey corrosive media containing solid particles ensuring the mud circulation in the solid control system provide power for sand and mud removal equipment it can also be used for fluid transportation in processes such as oilfield water injection fracturing adaptive various types of reciprocating pump equipment under harsh conditions
5. The piston is adopting a polyurethane + metal composite structure outer layer wear-resistant and corrosion resistance adaptive the medium containing solid particles and long service life good sealing performance and reduce medium leakage the volumetric efficiency of the booster pump and compact structure easy installation and replacement reduce maintenance costs can be adapted to different types of mud pumps broad application range, resistant to impact and fatigue can adapt to high pressure high-frequency reciprocating working environment and ensure the stable operation of the equipment
