The present invention has the following key assemblies:
Plunger pump and high-pressure discharge system: including the plunger pump, the plug valve, the high-pressure safety valve, a discharge pipeline, etc., which can convert low-pressure fluid such as mud, drilling fluid, acidizing fluid and slurry replacement, etc. into high-pressure fluid, and different pressures and displacements are obtained by changing plunger diameter, thus realizing liquid pumping and meeting operation requirements.

Alternatively, an automatic mixing system can be used to automatically control an engine throttle and a gear of a gearbox according to pressure and displacement requirements, so as to completely liberate operators.

The operation situation on the cementing equipment can be observed through a camera at a distance, so that the operators can be immersive and achieve the operation experience of what you see is what you get.
Hydraulic and air path system: mainly including a hydraulic pump, a hydraulic motor, a hydraulic oil tank, a hydraulic valve, a lubricating gear pump, a dryer, a air cylinder, etc., so as to provide power for the centrifugal pump, a pneumatic head and lubrication of the equipment to ensure normal operation of the equipment.
Main functions of the electrical system are:
(a) controlling the engine to start;
(b) controlling the mud mixing system;
(c) supplying power to electrical components to ensure that all indicator lights are on during operation, such as a touch screen, the instruments, a locking indicator light and an overpressure indicator light, etc;
(d) supplying power to all lighting lamps to ensure that the equipment can work at night; and
(e) realizing power supply by a storage battery. After the engine is started, a generator of the engine will charge the storage battery. The voltage of all electrical devices on the equipment is 24 VDC.
One plug valve of the air path system is the main switch of the air path system. The filtering pressure reducing valve connected afterwards can not only adjust the working pressure of the whole air path system, but also filter the gas entering the system to ensure the normal operation of air path components. Its main functions are:
(a) controlling on/off of the pneumatic actuator;
(b) controlling an air horn;
(c) providing air for the packing lubrication system; and
(d) providing air for a diesel spray bottle.
The hydraulic system is an open/close system, and the pressure of the hydraulic system during working depends on an external load, so as long as the system works normally below a design pressure, it means that the hydraulic system operates normally. An engine starting system, a motor drive system of a centrifugal pump, a motor drive system of a mud mixing tank agitator, a drive system of a cement discharging cylinder and a drive system of a hydraulic plug valve of the present equipment are all of a hydraulic drive type. All hydraulic components of the hydraulic system are from world-famous brands with stable and reliable performance.
A lubrication system adopts plunge pump power end lubrication and packing lubrication. Power end lubrication is composed of a set of independent systems. A gear pump is driven by the transmission side of an on-platform gearbox to apply continuous oil pressure forced lubrication to bearings and gears at a power end of the plunger pump. The gear pump sucks lubricating oil from the oil tank, the lubricating oil flows to the power end through a pipeline after passing through a pipeline filter, and then is divided into two paths: one path enters a main shaft to lubricate rolling bearings and sliding bearings of a connecting rod through holes of the main shaft, and the other path enters the gear box for lubrication, and finally the lubricating oil returns to a big pump lubricating oil tank. A safety valve is installed in front of the pipeline filter, which adjusts the pressure of the whole lubrication system. When pressure exceeds a set value, the lubricating oil flows back to the oil tank through the safety valve. The system is equipped with an automatic cooling device, which conducts cooling by means of an engine fan. When the temperature of the lubricating oil reaches a set temperature, the lubricating oil enters a cooler for heat dissipation. For packing lubrication, lubricating grease can be used to lubricate a plunge pump hydraulic end packing or centrifugal pump packing. An electric lubricating device forcibly presses the lubricating grease into the plunge pump or centrifugal pump packing. In order to avoid waste of the grease, the electric lubricating device is set to run intermittently to provide the most reasonable amount of lubricating oil for the packing. In this system, a one-way valve plays a role in preventing backflow of the lubricating grease. This lubricating fluid can use the “gas cap oil” lubrication method.
The plunger pump system mainly realizes different plungers, pressures, etc. to obtain different pressures and displacements required by end customers, so as to meet customer requirements.
The high-pressure manifold system is the general name of high-pressure pipe fittings of the equipment, which mainly consists of a 2″ plug valve, a 2″×1″ plug valve, a 2″ safety valve, a pressure sensor, an integral straight pipeline, a high-pressure tee, a high-pressure elbow, etc. The high-pressure manifold system mainly realizes the connection between the plunger pump and various plug valves, and extends the discharge port to a suitable position for external connection to a well site, and has other functions such as pressure measurement, manifold switch control, pressure relief and overpressure protection, etc.
The mixing system assembly is mainly used for mixing cement slurry, and mainly includes a mud mixing tank, a spray mixer, a cement discharge valve, a diffusion box, a defoamer container, a stirring shaft, a cement adding manifold, etc. A high-energy mixer is a core component of the whole mud mixing system assembly. Clear water entering from the clear water manifold, cement entering from the cement discharge valve and cement slurry circulating through a secondary circulation manifold are mixed in the high-energy mixer, which is a main component for mud mixing. The cement adding manifold is a pipeline which provides dry cement for the mud mixing system of the equipment, and includes a connecting pipeline, a cement adding hose and a control butterfly valve, etc.
