Thermal oil pump to stop pumping how to solve

Improve the service life of circulating oil- conducting oil pump , there are a variety of techniques used in pumping oil pump, which includes the use of long plunger short pump cylinder structure, an increase of scraping sand tank, spiral groove, rotary piston, double-travel valve , O-ring seals on the end face and other structural improvements as well as the piston plunger carbon steel chrome, carbon steel spray welding, pump cylinder using carbonitriding, nitriding, boronizing, WC carbide seat and other materials improvement of. Oil pump stop working, the oil return valve should be slowly loosen until the pressure gauge slowly back to zero before the unloading of the pipe jack nut. It is forbidden to change the tubing or pressure gauge during load. Pump with double-acting jack heat transfer oil pump, dual-use oil pump with two ways at the same time is appropriate.
Structural improvements in reducing the cycle of heat pump components and grit contact probability and scaling has played a certain role, but the pump material is always in place, ubiquitous wear and corrosion problems can not be fundamentally eliminated. Various surface measures on metal materials such as plungers and pump tubes are also limited due to limitations of the metal material itself in terms of high temperature resistance, wear resistance to sand particles, corrosion resistance and the like. In this case, choosing a new type of material that is more wear-resistant, corrosion-resistant and heat-resistant than metallic materials to manufacture the various components of the pump becomes a fundamental solution to the above pump failure problem. Before the operation of the heat-conducting oil pump, the oil control valves should be released and then the oil pump should be started. After the air-load operation is normal, close the oil return valve and gradually screw in the oil valve stem to increase the load and pay attention to the gauge pointer Is it normal?
