Mechanical checks, utility checks, filtration, membrane squeezing, and cake washing are separate verification steps. The final sequence depends on the approved equipment, slurry, site procedures, and local safety requirements.
When to Use This Service
Use installation and commissioning support when a new filter press is being placed in an existing dewatering line, when a feed and filtrate arrangement is being built, or when a replacement machine must match an established site. The service is also useful when the equipment will be operated by a local team that needs a documented start-up sequence rather than informal advice.
- Confirm machine layout, access, lifting, foundations, drainage, and cake-removal route before delivery.
- Match feed, filtrate, compressed-air, wash-water, hydraulic, and electrical interfaces to the site design.
- Separate dry mechanical checks, water checks, slurry trials, optional membrane squeeze, and wash steps.
| Project stage | Decision to record |
|---|---|
| Before shipment | Approved layout, utilities, lifting plan, drawings, and responsibility matrix |
| On arrival | Package condition, parts list, identification, and storage or preservation needs |
| Before first feed | Mechanical, electrical, hydraulic, interlock, drain, and emergency-stop checks |
Installation Scope and Site Information
A practical installation review starts with a marked-up general arrangement, not a generic checklist. The customer should provide the available room dimensions, access openings, floor or foundation information, overhead lifting capacity, cake handling method, and the positions of existing tanks, pumps, drains, and control panels. The process owner should also identify whether filtrate is returned, treated, sampled, or sent to a separate collection point.
- Send layout drawings, foundation or floor details, delivery route photographs, and lifting information.
- Mark nozzle, pipe, drain, cable, compressed-air, wash-water, and control locations with units and elevations.
- Identify local electrical standard, available voltage and frequency, isolation points, and panel location.
- Confirm who supplies feed pump, air system, wash system, cake conveyor, filtrate tank, and guarding.
Commissioning Sequence
Commissioning should proceed from safe, low-risk checks to a controlled slurry trial. First inspect the delivered equipment against its identification and packing record. Then verify that the frame, plate pack, cloths, hydraulic closing unit, feed manifold, filtrate outlets, guards, sensors, and control cabinet correspond to the approved configuration. Do not introduce slurry until the installation team has recorded the pre-start checks.
A dry run confirms movement and control logic; it is not proof of filtration performance. A clean-water or utility check can reveal leaks and drainage problems without confusing them with slurry behaviour. The slurry trial should use an identified sample and a defined objective. Feed pressure, hydraulic system pressure, and any membrane squeeze pressure are different values and must be recorded separately. If cake washing is specified, washing and filtrate collection should be confirmed as a separate step rather than mixed into the default filtration cycle.
| Step | Practical check | Record |
|---|---|---|
| 1. Receipt | Inspect frame, plates, cloths, controls, accessories, and transit condition | Exceptions and missing-item list |
| 2. Mechanical | Check alignment, plate movement, fasteners, guards, manifolds, and drains | Pre-start checklist |
| 3. Utilities | Verify power isolation, hydraulic unit, air or water connections, and emergency stops | Measured site values and open actions |
| 4. Dry function | Run approved movements and control sequences without slurry | Alarm, interlock, and movement results |
| 5. Trial | Introduce identified slurry under the agreed operating boundary | Feed observations, filtrate, cake release, and next steps |
Operator Handover and Safety Boundaries
Never open a plate pack under pressure. Never perform electrical work while energized, and never bypass a guard, sensor, emergency stop, or other interlock to continue production. Before inspection, cleaning, or maintenance, stop the cycle, isolate the relevant energy sources, release stored pressure according to the approved site procedure, and verify a safe state. Chemical cleaning must be selected for the actual cloth, plate material, slurry, and site rules; Shengqi does not provide a universal chemical recipe.
- Use a signed pre-start and shutdown checklist for each shift or agreed operating period.
- Keep feed pressure, hydraulic pressure, squeeze pressure, wash steps, and alarms in separate records.
- Escalate leakage, abnormal movement, damaged cloths, plate damage, unusual noise, or repeated alarms before restarting.
Information to Request Support
For a site-specific review, send the equipment nameplate or purchase reference, general arrangement, photographs of the installation area, utility details, and the slurry information already available. Include the intended process objective, operating hours, cake-handling route, and whether a trial sample can be provided. If the request concerns a replacement plate or cloth during installation, add clear front, rear, side, handle, hole, sealing, and connection photographs before any part is ordered.
| Send first | Why it matters |
|---|---|
| Site layout and photographs | Checks access, working clearance, lifting, drainage, and cake handling |
| Utility schedule | Separates available services from equipment that must be supplied |
| Slurry and process data | Sets the boundary for trial planning and operating observations |
| Approved drawings and scope | Prevents assumptions about included modules and interfaces |
Frequently Asked Questions
Can commissioning confirm a fixed filter press capacity?
A site trial can document the tested slurry, cycle observations, filtrate behaviour, and cake handling. It should not be treated as a universal capacity promise. Capacity depends on the selected plate pack, cloth, slurry properties, operating sequence, and site conditions.
Does installation support include every auxiliary machine?
No. A feed pump, polymer system, conveyor, cake breaker, wash-water equipment, tanks, and controls must be listed in the approved scope. Installation planning identifies interfaces and responsibilities; it does not silently add unconfirmed equipment.
Can an automatic press also use membrane squeezing?
Yes, automation and membrane squeezing describe different aspects of a system. The control sequence and the selected plate and membrane configuration must be confirmed for the material and process objective.
